Default Bloatware Must Die! (My noob rooting journal)

I finally reached my saturation point, deleting apps I like because of megs and megs of bloatware on my Optimus T. All I want to do (at this point at least) is delete the bloatware, and maybe run a low-level backup using (root-only) Titanum Backup. I don't want to overclock the poor thing -- it wasn't built to be a sports car, and I don't want it to become a $200 space heater. I don't want to install new ROMs so that I can flash it at my buds and pretend it's an iPhone with a purple case. I just want to get rid of the crap.

So, for the benefit of my fellow noobs, here's the step by step process I followed.

* Research the crap out of the whole concept.
Although I'm a programmer, and I'm familiar with Linux, I've never gone to the trouble to root any of my devices. The most I've done is helped my son understand that the mass of digits on the Game Shark 64 screen are actually DWORDs, and that you can spell things like 4AC0FFEE and DEADBEEF with hexadecimal numbers. So I wanted to make sure I had some clue what I was doing. (By the end of this process, I'll know if I succeeded in that task!)

* Download z4root
All roads seem to lead to this post on xda-developers.com. Thanks to the handy QR code in the post, I was able to drop the .apk file directly onto my SD card.

* Install z4root
Astro wasn't working -- it's on the SD card, and this phone frequently loses track of SD apps (which is one reason I want to free up phone memory space). But I was able to open the z4root apk file from my browser (xScope).

Note: if you're not familiar with installing outside the Android Market, a good start is to go to Amazon and follow the process for installing *their* market app. For obvious reasons, you can't get it from the Android Market.

* Unmount the SD card
I saw this advice somewhere, and it seems like a good idea. z4root installed to the phone, so it's still available at this point.

* Run z4root
So, I have the choice of Temporary Root or Permanent Root. There's no promise that Temporary will actually work -- well, there's no promise in any case, but Permanent at least has been tried more often. So I just jumped in and hit the Permanent button.

* USB debugging
Oops, I forgot to turn on USB debugging. z4root sent me to the settings page, where I turned it on.

* Run z4root again!
After some grinding, and some messages at the bottom of the screen, I was taken to a blank white screen showing only the notification bar. Then the phone rebooted. At this point, I wondered if I should have taken out the SD card physically, since rebooting of course re-mounted it.

* Wait wait wait
The phone normally takes a while to load everything after a reboot, but this time it seemed to take even longer. But once I looked away to type this, my gadgets finally reappeared. Everything seems normal; Gmail works, txt receiving works. I'm wondering how I can even tell that I've changed anything?

* Delete something!
So, can I just delete the crap now? Went into Applications and headed straight for the biggest offender: 10MB behemoth ThinkFree Office. Can I uninstall it? NO, not from the app list, not from the app info page. It's not going to be *that* easy.

* Whoa, what's that?
There's a new application showing up in the list with the other non-deletable "Applications": Superuser. YES! But clicking it doesn't cause my phone to leap tall buildings; it's where I set things up. Unfortunately, I don't know *how* to set things up at this point.

* Take a break
That's enough excitement for one playdate. I'll do some more research and see how I can use my new, Godlike powers. Meanwhile, I'll watch for any strange behaviors that would prompt me to back out. But the bloatware's days are numbered.

I'll post an update when I get back to poking on the phone. Meanwhile, any suggestions (and cautions, especially those) are heartily welcomed!

Ok, I couldn't wait any longer to try out *something*, and it occurred to me that the next logical step was:

* Install Titanium Backup
It's a biggie, so I moved it to the SD card (at the suggestion of App 2 SD Pro, one of my favorite time-savers).

* Run Titanium Backup
Lo and behold, the Superuser program popped up! That's when I figured I should log back in to androidforums and make sure I added more info.

* Learning from Dawdling
I got to learn an interesting tidbit about Superuser: it doesn't wait forever for you to answer. Good security feature. It closed without granting SU, and Titanium told me to try again later.

* Try again
It took a while to figure out that I had to re-open Titanium and pick "Reload application" from the menu. This time, it worked! It told me to go tick the USB Debugging checkbox -- which I had done earlier, but sure enough, it wasn't ticked (probably because of reboot). Looks like there's lots of cool options to learn about, yay!

Gotta go now, will do some more after son's sports activity.

No time to play over the weekend... had to wait until I got to work today. Wait, something seems backwards there...

* I fire up Titanium Backup. It checks for SU access and finds it. It also tells me again about the USB developer mode, so I hop over and check it again. Titanium seems to be generating more "Superuser mode granted" options than it did before.

* A "#" shows up in the Notifications area, telling me "su binary outdated". I click the message, expecting a Market update... silly rabbit! A Linux-style screen displays and I'm asked whether I'm ready to upgrade from a 2.x.x to a 3.x.x binary. That's a pretty big jump, so I back out.

* I was actually away from my PC when I tried that, but I wanted to poke a little more. So I tried the "Clean up the Dalvik cache" function. It did a lot of work, as far as I could tell, popping up "Superuser mode granted" over and over (assumably, for every Dalvik cache). Then at the end of several minutes, Titanium grinned to itself and told me it would have freed up over 9MB, but since I hadn't upgraded to Pro, NO CAKE FOR YOU! Gee, maybe I should have been told that *before* the cache purge process started? (But I'm still planning to fork out the dough once I've proven to myself that this process is worth it.)

* So I'm back at my desk, avoiding any real work (o hai boss), and I'm hitting the "Backup/Restore" button. After the one-time plug for Titanium Media Sync (which sounds kinda interesting), I see the big list of stuff to back up. Interestingly, the pre-installed apps (including crap like "Diner Dash 2 Demo 1.4.2") are in red. What I don't see is a way to actually DO a backup.

* Schedule doesn't seem to have an option to change what's listed as scheduled backups, and I don't see anything saying "Back up the whole blasted phone". The "Add new schedule" adds a bunch of identical functions that I can't get rid of.

* But "Edit Schedule" seems to give me what I need. I take the first added schedule (leaving the two originals, since they're probably the ones I'd actually want to schedule) and change it to "Backup all user apps + system data". I cross my fingers and hit RUN.

* Titanium minimizes itself, leaving an icon in the notification bar, which I can pull down to see the status. With each app, the "Superuser permission granted" box displays. It'll be doing this for a while, I can tell, so I'll post what I've got so far and look busy for the boss.

Next up, hopefully: Search-and-destroy the bloatware that sparked this odyssey in the first place.

Well, the backup worked... and now the Titanium Backup app list is populated with interesting information about each app. I especially like the distinction between "System service" (red) and "System service with useful data" (green).

Time to terminate with extreme prejudice.

* First victim: Diner Dash Demo. Listed as a System Service (lol). For fun, I hit Freeze, just so I could see Titanium beg for money.

* Ready, fire, aim: I hit Uninstall. A warning displays pointing out that if I bork the phone, it's my own stupid fault. Yes, I want to uninstall this critical system application.

* Titanium is granted SU, several times, and Diner Dash Demo is Dead. It shows on the list with a line through it.

* A check with DiskUsage (another favorite app) still shows the corpse there (com.glu.android.diner2demo), still 452kb being taken up. But the app is gone from the Applications list. App2SD reports 24MB free now. (Note: at this point, I didn't actually realize that the app seemed to still be there...)

* Tried to order by size, but the "ordered by (click to change)" doesn't seem to have that as an option. Or at least, it's not in the first few options. I would have quit trying after it went through several minutes of "Building data freshness information" for a sort method I really don't care about at this point... but then it was stuck on that. So I hit it again, and it spend another several minutes building "exact app size" information. Which isn't totally useless -- though I really don't care that my next victim is 10MB vs 9,655,350 bytes, I just want to kill the big, useless apps. Guess I could have used the Filter function, but I'll save that for another time.

* Time to jump ahead several levels and defeat the boss: ThinkFree Office, app = 15.9mb.

* Result: Success! But App2SD still reports just 24MB free. DiskUsage shows a big, ugly com.tf.thinkdroid.lgeglobal as taking up 10.0MB. Did I not have the tools to defeat the big boss?

* Being a Windows programmer, I did what we always tell our clients: reboot and try again. Will come back to the thread after that task (and at least one look-busy email to the boss) is complete!

Strangeness... clearly, I don't fully understand the intricacies of Android OS memory allocation. Rebooting removed both Diner Dash Demo and ThinkFree Office from the phone, and they no longer show up in DiskUsage. But I still only have 24MB free. However, I think the "System data" box in DiskUsage has increased in size -- it's now 48.4MB (but I don't know what it was before.

But heck, it feels good to get rid of the crap I don't use, seeing as how it's MY DANGED PHONE. So I'll go ahead and put a gun to the head of the following (thanks to http://androidforums.com/this ROM thread for a list of stuff I likely don't need):
* AppPack
* DoodleJump
* DriveSmart (deleting this one is said to help performance, battery life, startup time)
* DualClockWidget (what an amazingly useless dual clock!)
* Live Wallpaper Picker (also "Android Live Wallpapers" and "Magic Smoke Wallpapers")
* Pacman
* Google Talk
* Web2GoHome

Stuff from that list that I don't see on my phone:
* GenieWidget
* Protips
* Visualization Wallpapers (Maybe that's "Magic Smoke", above)

Stuff not on that list that look deleteable
* Alarm clock
* Analog clock
* Car Home (two versions shown, but both are 2.2!)
* Home Screen Tips (n00b that I am, I do think I've outgrown this)
* Telenav GPS (seriously, you want me to pay for what Google does better for free?)
* Something called "Power Off 2.2", that looks totally useless. (j/k)

Pre-installed apps that I actually use, and will keep:
* Facebook
* Maps
* My Account (not very useful, but wouldn't want to make T-Mo... I mean AT&T&T mad)
* StreetView
* Twitter (though I only use it for syncing contact icons)
* YouTube

There's a few others that I might delete, once I'm sure of what I'm doing. I think I'll let the phone mellow for another few days before plucking more than the low-hanging fruit.

BTW: Titanium's order-by is saved between reboots, so it started up with a long recalculation again. But it turns out that a long-press pops up a list of sort orders. I think I flunked the n00b test (again).

I picked a few more low-hanging fruit, including "Drive Smart", and I'll know over the next few days whether getting rid of that one will help performance and battery usage.

Some Googling ("android system partition") has taught me a bit more about the /system partition vs the /data partition. I'll try to learn more before I do any deep poking there. It seems like I should be able to move apps from /data to /system, but I'm sure it's more involved than that. (Heck, I don't see why I can't just resize the partitions, except for the change of completely losing my data like I did when I "just" resized my hard drive partitions one time!)

And I'm updating that su binary now:

* Click the Notification message.
* Console-style window displays showing that I'll be updating installed version 2.3.1-ef to 3.0.3.
* Google around, find androidsu.com and a peaceful, easy feeling.
* Say ok, watch cool command line messages scroll past, smile inwardly at the developer's wit.
* Run Titanium again. SU asks to verify root access (permission list got reset, which I think is a Good Thing).

No problems with the SU update. I know, anyone who's installing custom ROMs and overclocking their phone wouldn't have even hesitated, but maybe this note (like this thread) will help give other noobs like me the confidence to void their warranties.

Edit (instead of new reply): I've noticed a huge improvement in the accuracy of my Graffiti text input. Previously, it seemed like the CPU couldn't keep up with my finger swiping, which often led to problems. In fact, it's the reason I quit using the Swipe keyboard -- a stroke from point A to point B would be broken or drop out somewhere in between. This is definitely a change since I rooted out Drive Smart -- I can't imagine any of the other apps I smashed today could have had a similar impact. ROOT FTW!

First real glitch encountered!

I tried to use Titanium Backup to delete WiFi Calling, a useless "feature" that I couldn't even get to work, but which always starts up. If I recall correctly, it lets you use your wifi to make calls, but still takes the minutes out of your account, which makes it almost entirely useless. Of course T-Mobile's coverage stinks -- my living room is an "emergency calls only" zone -- so maybe I'd have used WiFi calling if I could have made it work. The only good thing I see coming from the AT&T&T merger is getting access to those additional cell towers.

Anyway, I hit the kill switch on WiFi Calling, and it appears to have been successfully deleted. But then I get a Force Close message on com.android.kineto (the WiFi Calling app). I hit the FC button, but the message appears over and over and over. I was afraid I was going to have to do a battery-out reboot, because the message appeared over the "Power Off" dialog, but by pushing the button and pushing the "power off" option quickly enough, I was able to get it to shut down -- despite the FC message appearing over the shutdown screen.

Powering back on... no problems noticed. Just a little bit of excitement! It's probably a good sign... if the app was holding on to the edge that desperately, it was probably dragging the system down the whole time.

I've also started breaking other rules, moving downloaded applications to the SD card. That was a little exciting too... on my first try, Titanium Backup got stuck in "Processing" and I had to power cycle to get it to quit. But the app did get moved!

It looks like it's about time for me to upgrade my Titanium Backup. It's definitely worth the six bucks and change for what it's done already (even though the app itself claims a $5.99 price, lol). It looks like that would let me move the apps I actually do want to keep on my phone into that increasingly-empty System partition (54MB free now vs 23 MB in regular space), using the pro-only "Convert to system app" option.

If that works, I may move some "System" apps, like Twitter and Facebook, off to the SD card. It looks like the process would be to use the "Convert to user app" pro-only option, then move the app to SD (voluntarily or otherwise). That should be smoother than the free alternative: delete the app and then get it from the Market, which would have the same effect but would lose my settings.

Basically, root access and Titanium Backup are letting me actually manage my phone's three memory spaces:
* SD card for non-widget apps that I can live without if needed
* Data partition for apps that I might delete
* System partition for apps I'm going to keep

Of course, it would have made more sense for the System partition to actually contain, well, System apps. But they made it so big (thanks to bloatware), I don't think I can justify just letting that space go to waste.

(Side note: Nobody has replied to this thread, but it's getting plenty of views. I've found that such a condition means either my brilliant prose has answered everyone's potential questions fully and completely, or else I'm full of crap and everyone's laughing to themselves cuz they're too polite to say STFU NOOB. I'll go with the first one, at least in my own mind.)

Robert,
I was in the same situation as you...I only wanted to root & remove the bloatware. I have no desire (at this point, anyway) to install a custom ROM. After reading your posts it prompted me to root my phone as well. I followed the guide at Android Central [How-To] Root, Recovery, ROM without touching a computer. Although everyone says this method is outdated I found it very simple to follow. Everything worked perfectly.

I too have found that simply removing the bloatware via Titanim Backup doesn't automatically increase the disk space. The Dalvik cache needs to be cleaned, which the free version of TB won't do. However, you can boot into recovery mode by opening Android Terminal Emulator (Free) and typing "reboot recovery" (without quotes), or by powering off the phone and when the phone is off press and hold (Volume down + Home button + Power) until the recovery screen comes up. Once in the Android System Recovery use the volume button to scroll and the menu button to select. Choose wipe, select Dalvik cache. Doing this gave me back 25mb of internal storage.

Hope this helps someone,

You're not kidding about the Dalvik cache cleanup. I did upgrade to Titanium Pro, and the first thing I tried was the Dalvik cache cleanup. I figured it would unload a few meg -- but it was more like 30MB! Holy crap, that more than doubled my puny available space.

I was guessing that the cache would just get rebuilt over time, but it's been about a day and I still have the space. At this point, I hardly even need to bother moving stuff around between /data and /system, because I've got more space than I've had since I got the phone.

So I tried moving an app from User to System... and it didn't go quite as expected. Fortunately, the first "beneficiary" of the process was one I could live without: "Barcode Scanner" (the ZXing app and library used by many other barcode apps). I figured if something went wrong, it could be easily reinstalled, and I wouldn't lose any setup parameters.

But when I told Titanium to move the app to "Convert to system app", it just stayed at "Processing" forever. After five minutes or so, I even tried Astro File Manager's task killer to kill all the Titanium processes, to no avail. I had to power-cycle the phone.

When I got back, Barcode Scanner was gone. Not a user app, not a system app... it was gone, and apps that use it (like BarClone, the only no-GPS grocery card app) complained that it wasn't there any more.

So I got to try out Titanium Backup's eponymous Backup function! It worked like a charm, brought it right back.

Then, I noticed Titanium has a "Problems?" button right on the opening page. One hint the button includes is, "If it hangs during some operations, hit 'Preferences' and set 'App processing mode' to 'AUTO, Indirect'". That's *exactly* what's been happening, so I did what it said (the option is way down the Preferences list).

Tried again: move Barcode Scanner to System. Poof, it's now a red-letter application! "Uninstall" is no longer an option, either from the app info page or from the Market.

I'll do some more poking when I have time, but so far, rooting my Android has been a fun and educational process, and it's left me with twice the phone I started with.

Interesting tidbit on moving an app to System. I converted Barcode Scanner and App 2 SD to both be System apps, but then I noticed that they no longer showed up in the Android Market when I listed "My Apps". Bad news, I thought: if the Market didn't see them installed, I wouldn't be able to get updates! So I figured I'd just use the freed-up Dalvik Cache space and be happy.

Well, over the weekend, App 2 SD had an update. Lo and behold, it showed up on in the Market after all! I installed the update, and App 2 SD now shows up in "My Apps". And strangely, so does Barcode Scanner!

I figured this was good news, though. At some point, the phone does see apps that are added to the System partition. So I moved the app that I really do want to keep safest of all: Titanium Backup. And sure enough, it doesn't show up on "My Apps", but now I know that I'll (most likely) get my updates. So I'm going to start moving the rest of my most-have apps to System.

One thing did break, though: my App 2 SD widget now says "Problem loading". Well, actually it says:

Prob
lem
load
ing

... because the text is crammed into a 1x1 widget space. But re-adding the widget worked without a hitch. It's good to know that, though, before I add Beautiful Widgets to my System folder (and break all its little friends).

It's a whole new phone these days. My friend has a new Android with gigs of memory, compared with the tiny 200MB on our Optimus T's, so I don't think he's going to be pushed to root for a while. But for this entry-level phone, I can't imagine going without rooting and aggressively managing the apps.

I've seen another nice side effect. I was having constant problems with my SD card apps. They would randomly go away, leaving a generic icon on the desktop that claimed "not installed". Unmounting and re-mounting the SD card (in Settings) would sometimes fix the problem... but sometimes it would just result in a different set of SD card apps going AWOL. I was worried that my SD card was going bad, but it was the second card to have the same problem.

Now that the bloatware is no longer hogging CPU time at bootup, my SD apps are no longer going randomly missing.

I assumed I would never need to root my phone, because I never planned to be an uber hacker with a pocket full of custom ROMs. Turns out that my low-end phone pretty much requires root to unlock its full potential. Huge thanks to this forum for pointing me in various directions, most of them right , and pushing me to take the plunge.

A few quick updates:

* I thought I'd converted Titanium Backup to a System app. I was wrong! Titanium Backup isn't included in Titanium's list of apps it can back up. What I thought was the app was actually just the Pro unlock key. Silly me, but sillier Titanium for not letting it back itself up. (Of course, how would you restore it?)

* One of my favorite "Freeze" victims is Voice Dialer. I never use it, but the easily-pressed button on my Bluetooth headset starts it automatically. Not any more.

* For some reason I can't figure out, Titanium won't let me move the "Graffiti" text entry method to System (or SD, for that matter). I wonder what they did to block it? I was able to move other keyboard apps to System with no problems.

Hello,

I got a kick out of reading your journal. I read it straight through to this post. If I counted the times I cracked up, I would need more hands! Last year around this time, I embarked on the same path you have taken. There are some eerie similarities--in your experiences and your experience (I was an assembly language guru back in the days of DOS). I especially enjoyed your "resize partition" mention! Having two older sisters, you could have evened the odds if we were brothers. <WEG> [wide, evil grin]

Thanks for sharing!

P.S. One disappointing fact about the Optimus T is that the processor is only 600 MHz. Had it been a full GigaHertz processor, it would run Adobe Flash. Flash is the reason I wanted to get an Android phone over a year ago. Boy, was I disappointed when I went to check it out and discovered it wasn't available. Neither is Firefox

Interestingly enough, this latest replacement unit shipped with a 4GB SDcard, whereas the previous unit shipped with a 2GB SDcard. Too bad I already purchased an 8GB card this summer.

I also fell victim to the phantom app syndrome. It usually happened with Opera Mobile. I would be browsing (with eight or nine tabs open) and the phone would slow to a crawl and then reboot. When it came back, Opera was gone! Good thing Opera Link saved all my settings and bookmarks. I find it unfathomable that LG even considered providing less than a gigabyte of internal storage. I mean, it is a camera phone, a web browser, and is a platform for graphical games! It's like manufacturing a bicycle with 4-inch tires! Hello?!?

Default Addendum instructions

Great write-up RobertB-DC, thank you.

I would like to add a few items to your excellent description / instructions.

1) If you are running Android Version 2.2.2 then z4root may not work. I had to use GingerBreak-v1.20 to root my phone.
2) Strangely, I see Superuser when I press the Apps button but not when I look under Setting -> Applications -> Manage Applications.
3) DO NOT PRESS Volume down + Home button + Power as suggested by mn1968. This reset my phone… oops.
4) For some reason Titanium Backup did not back up all of my apps and settings when I first ran it. (This became a problem when I accidentally reset my phone.) To avoid this problem, look for yellow triangles after your backup is complete.

Did you have a custom recovery flashed flashed when did this? I am by no means an expert but I have used this procedure many times without incident. Or could you have possibly navigated to the factory reset within the custom recovery and accidently hit that?

On a side note, I have flashed a custom ROM (Cyanogenmod 6.5.8) and let me tell you...it is absolutely impressive! There are so many tweaks and settings...not to mention the amount of internal storage it frees up. I do reccommend it.Just be sure to save all contacts, etc... as flashig the ROM will wipe all existing data.

P.S. Why didn't my highlighted quote from matiasch get formatted into a nice grey box?

You didn't format it correctly. It should have ended with [/ QUOTE] (without the space) instead of QUOTE]. Hit edit and add the [/ in front of 'quote' and it will be fine

That's something I hadn't thought to try! Sure enough, DriveSmart is still listed there. Clicking it generates a Force Close on Settings (process com.android.settings). But deleting DriveSmart hasn't caused any issues beyond that glitch, which is easily avoided. Though now that I know about it, I may go in to Settings and hit DriveSmart occasionally, just to show the phone who's boss.

Have you tried to remove Carrier IQ? That's the program that manufactures secretly put on all phones to spy on you with (see this page for more information).

Actually, according to the Lookout Carrier IQ detector (market link), my Optimus T doesn't have Carrier IQ. I got mine in June 2011 -- I wonder if newer purchasers have it, and I wonder if rooting my phone and killing the bloat prevented T-Mo from adding it? I think I'll make a thread for that question, cuz I'm curious now.

They probably called it something else back then I think it's listed under IQRN and I couldn't find any such listing on my Optimus, so that's one more reason to love this phone

I think it would bog down the little 600Mhz processor so they didn't use it. There is probably a more primitive version of it on our phones though... something worth looking into

I've been using SMS Popup (market link) almost since I got my phone, because it's lightweight and efficient. I gladly sprung for the $2 donation, too, even though it's totally voluntary (the app isn't crippled or ad-driven). I even used Titanium to move it in to ROM.

But now that I've got more space, I'm trying GO SMS, the hugely popular SMS replacement for the clunky messaging program on the Optimus T. I decided I'd had enough when I saw that nobody else's Android seems to be without a bubble-style conversation interface. And GO SMS seems to have all the features of SMS Popup... in fact, it looks as though they copied the configuration options word for word! That's not very nice.

Despite that moral twinge (ameliorated somewhat by the small donation I made to SMS Popup), I think I'm going to move SMS Popup out of ROM, freeze it, and move it to SD. I don't want to delete it, in case Go SMS doesn't work out. Then, I'll move GO SMS to ROM, because it's darn near 10MB! I couldn't have even considered installing it without going through the rooting and pruning process.

You know you can always delete it and still download it again from "My Library" if you want

Well, I figured that wouldn't make much difference, but I did it anyway.

Then I got to looking around, since my memory was hovering around the magical 20MB mark again. When I looked at memory use with DiskUsage, I found that all the apps I'd downloaded from Amazon's Free App of the Day -- and moved to SD, and frozen -- still had massive Dalvik caches that Titanium wouldn't get rid of. Turned out that freezing them only prevented them from starting at boot. That was great, but I didn't know they were still hogging memory even while encased in carbonite.

So I sent them all to the great beyond... and now I have 45MB free. D'oh!

I'd say I can't believe I was that dumb... but now I've got enough experience being dumb to *totally* believe it.

I only use the 'freeze' option for testing purposes. I thaw out the app and delete it once I'm certain that it won't cause any issues. I also do a backup and then store a copy of the backup just in case I need to restore the app again if it's not available.

Notsure After zroot4 installed, wifi and sd card not working

* Run Titanium Backup
Lo and behold, the Superuser program popped up! That's when I figured I should log back in to androidforums and make sure I added more info.

* Learning from Dawdling
I got to learn an interesting tidbit about Superuser: it doesn't wait forever for you to answer. Good security feature. It closed without granting SU, and Titanium told me to try again later.

* Try again
It took a while to figure out that I had to re-open Titanium and pick "Reload application" from the menu. This time, it worked! It told me to go tick the USB Debugging checkbox -- which I had done earlier, but sure enough, it wasn't ticked (probably because of reboot). Looks like there's lots of cool options to learn about, yay!

Gotta go now, will do some more after son's sports activity.
Hi,

Kindly help me out please...

Thank you for the detailed information, and I am a new to android and rooting. I have LG optimus T unlocked phone.

I have installed zroot4 and selected permanent root. Phone rebooted looks good.
I have downloaded Titanium Back up and try to remove carhome2 and my nightmare started.

Phone rebooted and wifi is not working it says connecting and disconneted.

It does not recognize SD Card and no app is visible, but when I connect it to my laptop and all the apps are visible except zroot.

Your help is appreciated. What I need to do ? Is there any way I can uninstall root from laptop ? or what I should do ?

Thanks

I had trouble with my phone reading my SD card, and I've assumed all along that it was because it had so much bloatware starting up at boot. But I also replaced the SD card at about the same time (I think). The old card was an old card I'd had laying around, but the new one was an 8GB SDHC card. I've been wondering if the phone does better with the newer SDHC interface. If you're continuing to have SD issues, I'd suggest trying a new SDHC card. They're dirt cheap now!

It depends what you're doing at the time. If you're taking pictures then a class 10 will help. But for using apps it won't matter all that much. It's basically how fast you can record to the card. The higher the card, the faster the response. I'm using a 16gig class 10 and it hasn't made much difference. But as you said the cards are cheap so why not use them?

My new favorite feature of Titanium is the recently added Batch Function list. In particular, the function to integrate all system app updates into ROM. Just today, Google updated Maps and Search, and I'd already been sitting on updates for Twitter, GO SMS, and App 2 SD (all of which are in System). I could have integrated them one by one, but this is much easier. And there's a confirmation screen that lets you check/uncheck apps to integrate, so it's perfect. Integrating those apps got me back at least 10MB.

Noob note: I don't know if I mentioned it earlier (long thread is long), but this is a huge space saver, even if you never get rid of Diner Dash 2. Turns out that when you update a "system app", the update actually goes into your Data partition. So if the old version of Diner Dash 2 was 5MB, and the new version is 6MB, you actually end up with 11MB of space being used (5MB in /System, 6MB in /Data). That also explains why you can "uninstall updates" but not the app itself -- the pre-update app is in System and "can't" (lol) be deleted.

robertB-DC, wow, all I can say is thanks, I followed your post word for word and my Optimus T is now bloatware free. It rooted my phone perfectly. I have never done this before, but have always wanted to use my phone my way, not tmobiles way. And reading your post gave me the courage to try it.
Now, do you know and what it is to ROM a phone. I now feel the urge to try that next. People like you is what makes forums cool, so thanks again.

I successfully rooted my LG Optimus T tonight by following the instructions on this thread as well as other threads I found in this forum and elsewhere.

I too was only interested in getting rid of the bloatware and freeing up phone memory. Trying to keep my internal phone memory above 20mb had become a daily chore. I have had to uninstall apps that I wanted to keep more times than I care to remember.

However, now I have a few questions. My concern is in uninstalling apps I don't want, like Diner Dash, TeleNav, etc.

This thread says to uninstall, while others say to upgrade to Titanium Pro and freeze the apps. I did uninstall the Diner Dash and Doodle Jump apps, but then got nervous and restored them from the Titanium Backup. It is interesting that the apps seemed to have been restored to the SD card, instead of back on the phone where they were.

I'm so scared I'm going to uninstall something crucial and my phone will stop working. So which is it? Uninstall, or freeze?

Thanks in advance.

P.S. also tips to free up space....in this thread when you were talking about partitions, I got lost.

Can you imagine *any* core function of your phone that would possibly be impacted by not having Diner Dash 2 installed?

It's pretty easy to figure out the low-hanging fruit and pluck it. If it's a game, you can safely delete it and not even look back. If it's a handy app that you don't use (or that wants you to pay, like TeleNav), you can blow it away and not care.

If you don't know exactly what it is, leave it alone. For example, you might not recognize something called "LG Home", so don't delete it! (It's your home screen manager: kill it and you've got yourself a $200 paperweight.)

Here's a hint: if you can download it from the Android Market, you can probably get away with deleting it. Example: all those T-Mobile specific applications. They worried me the most, because I was concerned that they might be interacting with the network in some way I needed. Turns out they didn't -- they were just another way of letting T-Mo bug me to upgrade to Caller Tunes and other stupid "features". (Caller Tunes: Subject your friends to your crappy musical tastes for just a few bucks a month!)

If you're wondering why Diner Dash 2 is now on your SD card (where it belongs): Titanium deleted it from the System partition, but restored it to the SD card because there's an additional step required to stuff it back into System.

Don't worry too much at this point about all the partition stuff, though. Just getting rid of the bloatware will make you a much happier phone owner. Come back after you've done the easy stuff, and it'll make more sense.

Thanks for the tips!

So far I have uninstalled Diner Dash, Pacman, TeleNav, Visual Voicemail, Doodle Jump, App Pack, and Email.

But yet, no increased space on my internal memory.

What am I doing wrong???

Clearing the Dalvik Cache will take care of a big chunk of memory that they were taking up. Unfortunately, that function of Titanium Backup comes only in the paid version. It's worth it, trust me. Paying $50 for your unlimited data plan is pretty worthless if you can't download anything, so it's $6 well spent.

Also, don't forget to install "App 2 SD", which will let you clear the (regular) cache. And upgrade that one to paid, too, so you can have the handy widget to show you how much memory you have at any time.

Okay next step:

Now somewhere I read that rooting your phone allows you to move apps from the internal memory to the SD card, even if the developer did not specifically allow it.

How do you do that?

Thanks in advance.

That's where Titanium Backup comes in. You pick the app, and Titanium Backup moves it to the SD card, whether the developer likes it or not!

But be sure you won't give yourself unexpected headaches by moving the app. SD card memory is not guaranteed to be present, and is explicitly unmounted when you connect your phone to the PC and say "Turn on USB storage". That's part of why Widgets aren't very compatible with SD-based applications. But if you don't use an app's widget, it may be ok. I moved MLB 11 to SD, and didn't have any ill effects because I didn't use its widget.

Also, SD-based apps aren't available at bootup, so moving them to SD "breaks" activate-at-boot functionality. That may be a desirable side effect, though, on a low-end phone like the Optimus T. The more crap tries to activate on boot, the longer the boot process takes.

MLB...Major League Baseball??? At least that's what Google tells me.

When you say "widget" is that including shortcuts too? Or are you talking about the larger widgets, like for instance the Evernote widget that can take up to 8 spaces on the home screen?

By "widgets", I mean the things that you put on your home screen by long-pressing and selecting "Widgets". The big difference between a Widget and a Shortcut is that a Shortcut is a static link to run a program, while a Widget is an active content area. The active content can be anything:
* The MLB 11 program's widget simply displays your favorite baseball team's logo, and takes you directly to their page in the app
* GO SMS shows how many unread messages you have
* App2SD has a widget showing free memory and clearable cache
* There are any number of weather and news widgets

Since widgets are actively running programs, their parent needs to be available at boot time. The SD card on our underpowered phone can take several minutes to come up, so apps on the SD card aren't available to their widgets, which could generate errors. I'm not widget-crazy, myself -- the phone doesn't have the spare processing power to run a bunch of active content -- so I haven't noticed much problem.

Hi, all. Thanks Matiasch and Robert B.

I'm unclear about the reference to Android version vs. kernel version and choice of rooting ap. I'm running Android v2.2 Kernel 2.6 32.9. Should I go with Robert's root software choice or the one that you referenced?

Thanks again

Android is built on Linux, so the Android version and the Linux Kernel version are (I think) somewhat independent of each other.

It might be oversimplifying, but it's kind of like looking at your PC, where you might be running MSWord 2007 on Windows 7. If you have a Word add-on that requires MSWord 2007 or greater, the add-on probably doesn't care if Word is running on Windows 7 or Windows 8 (or whatever), as long as the Word version is compatible.

Does that help? (And to the experts: did I get anything wrong, other than the terrible faux pas of referencing Windows?)

Question

just a question sorta pertinent to the OP's P.
Maps/Latitude: I have this set to NOT autostart, I Have unchecked every plausible think I can come up with that might invoke it anyway, and still it cranks off at bootup.
Uninstall via Titanium will work, but I want it to use, or I shall replace it with something from Market that I can actually control [might be the better plan].

can someone advise as to what worked for you?
