ROOT LG Thrill 4G:

1.Make sure your phone is not set to read mass storage only.

Setting>SD card & phone storage setting>uncheck “mass storage only”.

2.Turn on Usb debugging

Setting>application>development>check “USB debugging”

3.Connect phone to PC via USB cable.

4.Be careful don’t click “turn on mass storage” and leave the phone as it is.

IF you are on stock ANDROID 2.2.2(froyo)

:both megatron_windows and super one click roots your phone.

{however I prefer megatron_windows than super one click as it has less probability to freeze than super one click.when I was on froyo I had to try 2nd time by super one click to root}

IF you are on stock ANDROID 2.3.5(gingerbread):only megatron_windows roots your phone.

Megatron_windows” root:

-After you have followed upto step 4 & connected your phone to PC,open “run” batch file as administrator,from the extracted folder.

-when batch windows pops up press enter .It will start rooting.It will reboot 2 to 3 times your phone while rooting.After it finishes rooting,it will prompt to press any key on batch windows.Hit enter and your phone is rooted.

“super one click” root:

- After you have followed upto step 4 & connected your phone to PC,open main super one click app from extracted folder and click “root”,wait for sometime until a message box “ says your phone is successfully rooted “and Run SU test,when it says SU test success your phone is rooted.

Now you can enjoy any root needing powerful apps such as “Titanium backup”.

FLASHING CWM RECOVERY & MAKING YOUR 1ST NANDROID BACKUP:

Flashing CWM is very vital for playing around with custom ROMs and before you flash any custom ROM by CWM it is must to make nandroid backup so that you can flash back to your custom ROM in case anything goes wrong.

Until there’s nandroid backup on your SD card and you don’t replace CWM recovery with your stock recovery you can go to your stock ROM any time you wish and hence there’s no risk of phone brick.
