LG G Flex 2These are the instructions to root LG G Flex AT&T H950 smartphones running Android 5.1 Lollipop or Android 5.0 Lollipop. Once you root the device, you can install all of the apps that wouldn’t work without access to the root file system on your device.

REQUIREMENTS

  • The following guide is made for the LG G Flex 2 AT&T H950 only. Each model number of the G Flex 2 smartphone has a unique code string to use during the guide. Therefore, by flashing these codes in the command line on a different device, you are risking bricking that device.

BEFORE WE BEGIN

  • Download the LG USB Drivers from our drivers page here. The LG drivers should definitely work since they are made for all LG devices. However, you may also install the ADB driver on the page and it will work for your device also.
  • Check that the Developer Options menu is unlocked on your device. You should see that from the Settings menu. Those who do not see it from the Settings must navigate to the Menu > Settings > About Device > tap the build number 7 or 8 times until that menu is unlocked.
  • Now that you have unlocked the Developer Options menu, head to the Menu > Settings > Developer Options and enable the USB Debugging Mode.

    Nice step-by-step.
    Can it be assumed that this works for AT&T 5.1.1 v11x and v11z ? Or only 5.1?
    If I have v11x, it is not clear whether the rooting image in the download of Step 1 is for v11x or v11z – will it brick the device if the versions do not match?
    I’ve read on xda that v11x cannot be upgraded to a rooted v11z without bricking the phone.

    Do I just leave the rootedsystem.img file in the “Internal storage”?

    Is there a stock unrooted “system.img” somewhere that I can copy off for a backup first?

    Is booting between rooted and unrooted images (for getting the eventual v11z and future updates) as simple as interchanging Steps 13 and 14 while rerunning the entire stepped procedure?

    Thanks!
