Root Optimus V Rooting,Roms,Tutorials thread

[asadullah]

This thread as the title suggests will be dedicated to rooting, roms, tutorials and other optimus v development related discussions. Please do not clutter it with idle chat or things like download link doesn't work. I have thoroughly checked everything that I post and will continue to do so. I take no responsibility for what you do to your phone.

This thread is a work in progress and will hopefully continue to grow as well as the optimus v community.

Anyways onto to the good stuff I'm breaking this thread down into different sections as such:
1 rooting and installing adb
2 available roms/ recoveries
3 general development (tips)

 

[asadullah]

Reserved so I can fill it out in a second

Okay so there's actually two ways to root the optimus v. For both ways you have to install the android sdk so lets get started on that first.

First go here and download the lg drivers then plug in your phone and turn usb debugging on I made a video on this awhile back here on how to install the gingerbread sdk. This will still work. While you watch the video you will have to replace the htc drivers with the lg drivers. There will be a remake on this just for lg so there is no confusion.

Root method One:
I like this method cuz it's pretty simple and I'm the first to post it . Plug your phone into your computer and make sure usb debugging is turned on. Download this zip file unzip it and place the .img files in your adb tools folder. Open up a command prompt and type

cd/
cd androidsdk/tools
adb reboot bootloader

Your phone will boot into a blue screen which is bootloader but will not be recognized. Install the fastboot drivers in windows by going to start/devices and printers/android device I clicked it and chose hardware/properties/change settings/driver/update driver/
It gives you two options automatically search and manual search. Choose
automatically search. It will install the fastboot drivers. Then in command prompt type this

fastboot erase system
fastboot erase boot
fastboot erase recovery
fastboot erase userdata
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot reboot

You can actually just copy paste this into command prompt

Here is the zip with the images and batch you'll need here

all done with method one.

Method two:
Go here and get superoneclick then grab this zip here. Then run super oneclick
I do this while super one click is still on but to each his own
unzip the file you downloaded and push shift and right click your mouse on the file
select "Open command window here"
copy and paste this into the command window

adb push tools/recovery.img /sdcard/
adb push tools/flash_image /sdcard/
adb push tools/boot.img /sdcard/
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
cat /sdcard/flash_image > /system/bin/flash_image
chmod 755 /system/bin/flash_image
mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
flash_image recovery /sdcard/recovery.img
reboot recovery

done

Right now there are several roms that can be used on the optimus v and some that are made specifically for the optimus v. I'll only list the ones made directly for the optimus v:

1) Stock Rom here
2) Pure Android here
3) Rhodimus Rom here
4) Stock Overclocked Rom here
5) AOSP's gingerbread Rom here
6) Zefies cm7 build here
7) Mobius Rom here
8) Aphrodite 1.x here
9) Aphrodite 2.x here
10) ZOMG! here
This is all that are available as of 3/31/11 If I missed some then pm me with the link and I'll post it

He got banned for God knows what reason and he probably won't be back to finish this

 

[pastafarian]

He's not banned, the "banned" thing is an avatar picture.

Also, all the links I tried appear to be fine, unless I'm missing something?

 

[michaeljr10wv]

NO, the zip on the second method after downloading superone click doesnt work...takes u to another page and when you click download file it's give a error.

Well then I'm an idiot. Sticking with the idiocy, you can only load one ROM at a time, correct? There's no merging or anything?

Im getting cannot load boot image and cannot load sytem img, and now my phone keeps booting into fastboot.

You are correct about the rom, but I don't think missing an avatar makes one an "idiot", unless there's something else you're not telling us?

I don't know the scope of Optimus development, but usually someone develops a "kitchen" that makes it easy for non dev's to make their own roms. Essentially picking the features you want from a list and then the software makes a flashable rom with those features for you.

A couple of good places to get an education on rom development

I think im not that smart either. I was trying to use the wrong zip file for the first method but the other one appears to be gone. Anything i can do or am i stuck at fastboot mode without the file.

I swore to myself I wouldn't reply to posts like this but watch the video on how to root your phone in the video tutorials section it will fix your phone if it's stuck in bootloader.

Please don't post this kinda stuff all my stuff works I been doing this for long enough to know when something is broken and when it's a user error. I'm talking about the past couple of posts I'm not pointing you out merlin.

 

[Merlin1]

I was not saying something doesnt work i just need the zip file for the first method and i cant seem to find it. Anything that happened to my phone was user error not fault of the ops.

I started using the first method as well and was well into the commands before I realized what I had done. I think the zip file is missing, but I used the recovery.img, boot.img, and system.img from this link: [How-to] Return your phone to stock(mostly)! - Android Forums to return it to stock.

I then used superoneclick and rooted it easily enough. This is my first time flashing an android device, so I'm probably just missing something extremely obvious.

I know. I just put up the fastboot files a minute ago here they are again here

Neither method works for me. Are there instructions for the newer Android SDK? I moved files around to allow me to use the adp command on the command line. But the USB drivers will not work. Following the first method I encountered driver issues. I downloaded the expansion for the Android SDK, but my phone (LG Optimus V) is not supported. The manufacturer's drivers won't work either. When trying the second method the "su" command is not recognized and the mount line is followed by correct usage instructions.

I'm running XP and failing hard.

1) Stock Rom here

First sentence from the linked post:

This is a slightly modified stock rom.

Any links to an unmodified, stock ROM?

 

[bigsupersquid]

...Any links to an unmodified, stock ROM?

you could look at http://forum.sdx-developers.com/optimus-guides-and-tips/how-to-return-your-optimus-v-to-stock(tested-by-me-needs-other-testers-please)/
I used the stock ROM from there together with xefie's Xionia kernel for the V and it worked fine.

I tried several different links to drivers which wouldn't recognize my V before using the lg download tool.
I captured these drivers after the lg download tool pulled 'em from the factory site. Running XPsp3.
you can get them here:

Perfect. Thanks!

Bigsuper - I tried the drivers you included and still no luck. The phone shows up as "android" in device manager, and it will not accept the drivers as being valid. I can reboot the bootloader from the command prompt, but when running the fastboot commands it hangs at "waiting for device". Any suggestions?

 

[funkwaffle]

a little more info...

Here's what the screen on my phone says:
Fastboot mode started
gpio_i2c: Invalid khz: 0
bl: i2c write error
udc_start ()
-- suspend --
-- reset --
-- portchange --
-- reset --
-- portchange --
-- suspend --

Your phones in boot loader you need to install the fastboot drivers. I did a write up on it somewhere. You can actually use my root method to install a custom recovery, rom and boot image. As a matter of fact it's in the video I made please read before you post or mess up your phone. Cuz it leads to these kind of situations when you don't.

 

[funkwaffle]

I was really hoping that the instructions would be covered in writing. The fastboot drivers do not automatically install themselves. Heck, they don't even manually install. Nowhere above is there anything explicitly stating where or how to get the fastboot drivers.
