My experience:

This tool really works on my LG Thrill 4G. Once you open the all-in-one tool and it says wait five seconds, count to five then put your battery back in. If you do it correctly it will vibrate when you insert it. If not, then restart the procedure. From here you can install the WKparks bootloaders and custom recovery. I installed the TWRP recovery manager, I like it way better than CWM. Easier to use IMO. After you install the recovery boot into it and make a backup. Install the Su_Bbox zip file on your SD card then boot back into recovery and install the zip. That’s it.

There is another way to root the device: (I haven’t tried it yet.)

1.- Download both files to the PC:

  • [Download]
  • Instalar Recovery ICS Europeo [Download]

2. Extract “Instalar Recovery ICS Europeo”, install the OMAP4430 drivers (you can find them in the folder)

a) Open device manager
b) Plug the device to pc by using usb cable without the battery,
c) You will see “omap4430 device” appearing and disappearing
d) As soon as you see it right click on it and chose proprieties
e) Click on the drivers tab and select update driver
f)Sselect the driver on the folder “usb_drv_windows” from the file you downloaded and install them
g) wait till it finish installing them

3. Now run the file “Instalar Recovery ICS Europeo.bat”, then

a) Connect the USB cable from the phone to the PC without the battery
b) Wait until the message “Wait 5-Seconds…”, then put the battery in.
c) Wait until installation is complete and you’ll see the green screen and the message.

Installed recovery!
Please remove the USB cable

d)Now you can disconnect the cable USB, remove the battery, return the battery, and boot the phone.

Follow the instructions and you will have CWM on the phone

4. Copy the “” file to memory (either internal or external SD card)

5. Boot into Clockwork Mod, shut the phone down all the way
a) hold down the 3D button, the VOL DOWN and POWER at the same time. (some say hit vol up but this didn’t work for me)
b) when the backlight comes on the screen, let go of the power and vol DOWN ONLY, keeping the 3D held down until you see the clockworkmod touch interface come up.
c) choose install zip from sdcard, find the file using the vol + and – keys.. then scroll down past the No’s to the YES and tap it on the screen.

Congratulations! Now you have a rooted ICS V30B.
