Step-by-step Rooting & Flashing guide for Optimus S.

[RazzMaTazz]

Does this work for the Optimus T.

I'm pretty sure that this won't work for the Optimus T. You should check out THIS Optimus T forum.

Can the optimus be flashed for boost?

I don't know. I'm pretty sure that it can be flashed to MetroPCS, but I don't know about Boost.

I love this guide and thanks a lot for taking the time to write it but I'm having a problem with the optiauto-sfx program. It always ends up saying that the "zerglings did not leave interesting stuff" which according to it means it failed? I've tried this about 5 times now and it still hasn't taken.
Also I don't have any of the baseband versions you've listed. Mine comes up as LS670MVJ_6150. Any help? I really don't care in the slightest about keeping the phone functionality since this "phone" is just a cheap iPod Touch and will never make a phone call again. In fact the reason I'd like to root it in the first place is to get rid of some of the Sprint and Android phone applications like the Gmail app that's taking up internal space.

Razz, why don

...I don't have any of the baseband versions you've listed. Mine comes up as LS670MVJ_6150.

I didn't list all possible basebands. In my original post, I wrote, "It'll be something like, "LS670ZVD..." or "LS670MVD..." or "LS670ZVH...", etc. There's no meaningful difference between a "Z" and an "M" so, for example, as far as this guide is concerned, consider "MVD" to be "ZVD" and "MVH" to be "ZVH", etc..." You have "ZVJ".

...I'm having a problem with the optiauto-sfx program. It always ends up saying that the "zerglings did not leave interesting stuff" which according to it means it failed? I've tried this about 5 times now and it still hasn't taken.

Optiauto-sfx.exe doesn't work with ZVJ so you have to follow the instructions for ZVJ.

I have a LG Optimus S phone. It will not come on. I have 3 fully charged batties. I have a car, home, and usb charger that I tried all 3. All 3 work with my other lg phone so I know it is not them. When I plug it into a charger, It flashes the LG light and the 4 buttons at the bottom will flash on and off. I tried the reset where you hold the home, volume, power botton down. That did nothing. Can someone please help.

Does this have anything to do with rooting or flashing the phone? If not, I'd suggest that you post a new thread in the main Optimus S forum. The only thing that I can suggest is pulling the batter for a few minutes, pushing the power button, and reinstalling a known-good, fully-charged battery.

Thanks for the step by step. Used cm7 and it's fantastic I won't have an android without cm again. Thanks again can't wait for cm10.

Windows should see your phone via USB regardless of USB debugging being turned on or off. (I just tested mine both ways.) Without USB connectivity Optiauto-sfx.exe has no chance.

Maybe try using a different USB port on your PC, or try with a different PC.

You may also want to try putting Optiauto-sfx.exe at the top level of your boot drive (probably your "C:" drive).

Razz,

Great post...I now have the confidence to attempt this.

I started with ZVJ, so I've downloaded the update.zip, and added it to the highest level of the SD card. I've done

Wow, look at all these new members - WELCOME to Android Forums, folks!

Hope you enjoy your Optimus and hanging out with like-minded enthusiasts!

Hello Razz,

I'm new to rooting. I followed the steps that you outlined and it seems my optimus s will not root. I tried several times with no luck. I went back to stock ZVD and when I run optiauto-sfx it finds my device but it seems most of the lines state that it is unable to chmod or data is read only or operations are not permitted. I pasted as much of the log I could copy below. Thanks for your help.

I'm not sure what you're asking. Usually if opti-auto-sfx ends up saying "It's a GG man!" then it worked. Are you saying it didn't work? When you start in recovery mode, is it the stock Sprint/LG recovery?

But your log does seem to indicated that optiauto-sfx can't write to your file system. If so, I'm not sure why. You could try launching optiauto-sfx from your top-level directory. Maybe that will help.

I tried launching the optiauto-sfx from the top level directory and from the desktop. I also tried running it as an administrator and still no luck. I did notice that when I turn on mass storage and check my sd card that a 000root folder is created and within the folder it has the files busybox, flash_image, su, superuser.apk, etc. I think I will try another USB cable or try launching from other directories and see if it takes. I would think since others had success mine should root as well. I'll just keep trying. Oh, and when I go into recovery mode it is the stock/Sprint recovery (Android system recovery <3e>. Thanks for your help on this. I greatly appreciate it.

 

[RazzMaTazz]

Hmmm... You've probably already done this, but maybe go into "Applications" settings and make sure "USB debugging" is turned on?

Yup. I have it on but I got it to work. I believe my anti-virus was blocking the program from executing properly. The first time I tried it the malicious software warning came on and even after trying when turned off it wouldn't work. I uninstalled my anti-virus, rebooted my computer, and it worked! Thanks a lot for your help on this!

 

[RazzMaTazz]

Thanks for letting us know about the anti-virus issue. I'll add that to my guide. Although I didn't have that problem with my Microsoft Security Essentials (MSE) antivirus software, it makes sense because when I do an antivirus scan, MSE red-flags Optiauto.sfx.exe as an Android "exploit". Of course that's exactly why we use Optiauto-sfx.exe-- BECAUSE it's an exploit. But antivirus software is made for normal people, not people like us who hack their phones.

Can someone give me a link to find a Cm7 mod download with the ls670? I couldn't find it on the website for this device! Thank you!

It should be on Razz's guide when he discusses about downloading a custom ROM. That's where I got it. I'm using it now and I think it's a really nice ROM.

 

[RazzMaTazz]

Thats rght. The main custom ROMs are listed in my guide.

Hey everyone,
First off, thanks for this guide. I'm having a problem getting started, and I'm hoping for some help. I need to downgrade VJ before I can do anything, but I can't seem to get the rooting to work. I enabled Debugging, and my computer sees the phone as a "Removable Disk (E: )" drive, but when I click on it, it says "Please insert a disk into Removable Disk (E: )". My phone says "USB connected" and "USB debugging connected", so I tried to run optiauto-sfx.exe, then when it finished I downloaded the Titanium Backup, but when I tried to run the Titanium Backup, it said my phone wasn't rooted. So I thnk the optiauto-sfx.exe failed because my computer isn't fully "seeing" my phone... Any ideas how to fix this?

EDIT: I should probably mention I've downloaded and run the newest drivers for the phone. I first tried the one linked in the first post, but when that didn't work, I Googled it and found someone else posted another Driver elsewhere on the forum, but that didn't work either so I went to the LG website and downloaded one. But it still isn't working right.

EDIT AGAIN: I figured I probably should say I'm running Windows 7. Also, when I turn on USB Storage, I can view the files on the phone (the E drive), but the guide says it turn USB storage off, so I don't know what to do...

EDIT AGAIN, I KNOW, SERIOUSLY?: Ok. I reran the .exe (this time as admin from my computer's root drive) and paid more attention to what it said, and mine said the same as Goalie30's posted above. Goalie30 says his problem was caused by an anti-virus, but I don't have an anti-virus, so I have no idea how to fix it...

As I mentioned in the guide above, if you were (are) on ZVJ, then you first need to downgrade to ZVD (using the instructions in the Appendix) in order to root using opti-auto.exe. Did you successfully downgrade to ZVD using the instructions in the Appendix? You didn't say. To determine which baseband you have, see the guide's section called, "How do I determine which baseband version I have?"
