How to root T-Mobile LG G2 that is running Android 4.2.2 Jelly Bean:

Remember that your device has to be running the same ROM version that it was installed on the day it was shipped.

  1. Download the Root package from here.
    - save this file on your computer.
  2. Extract the Root Package for TMO LG G2 archive.
    - place the extracted folder on your desktop.
  3. Use the USB Cable and connect your smartphone with your PC.
    - the phone has to be powered on.
  4. Go to IORoot folder, the one created in step 2, open it and launch a command prompt window.
    - to open the command prompt directly in this folder use this: press and hold Shift key, at the same time right-click on the folder’s white space, then select ‘open command prompt window here’ from the right-click context menu.
  5. Now, you have to see if your LG G2 is detected by your computer. Do it by entering the following line in the command prompt: adb devices
    if a serial number is shown, then the device was detected and you can continue to the next step.
    - in case the serial doesn’t show up, then you will need to switch between USB ports or re-install the LG USB Drivers. Also, check and see if the USB Debugging option is enabled in Developer Options.
  6. Return to the IORoot folder. Double click the ‘root.bat’ file.
    - press any key to continue when the new command prompt asks you. It detects the smartphone.
    - now you will need to stop for a moment and apply the actions in the next step, but don’t close the command prompt screen.
  7. Disconnect the T-Mobile LG G2 from your computer.
  8. Go to Developer Options section, disable and then re-enable USB Debugging.
  9. Use the USB Cable to re-connect your device with your computer.
  10. Now you can ‘press any key to continue’. Root will be started.
  11. When the Root is completed you can close the command prompt window.
  12. Return to the first command prompt window, the one you opened in step 4. Enter the following command lines:
    adb shell
    su
    id
  13. The following line has to appear for you to know that the root was successful:  uid=0<root> gid=0<root>.

These were all the steps you had to take in order to root your smartphone. If you have any questions, then you should ask for more help in comments.
