Get root on T-Mobile LG G2 running Android 4.4.2 KitKat (D80120a)

Following the AT&T, T-Mobile branded LG G2 (D801) also has an official KitKat update. Unlike the others, the update is currently not available via Over The Air (OTA), but you have to manually download the official firmware file (*.kdz) about 1.5GB of file size from LG’s site or PC Suite application, then we need to flash it by using the LG Mobile Support Tool. So for those who are less familiar with the manual firmware flashing, it is advisable to wait for an update via OTA.


One of the challenges that make some users think twice before updating is root, since up to now there is no working root method for T-Mobile LG G2 running Android 4.4.2 KitKat (D80120a ​​software version). The IOroot’s developer who previously constantly been successful in providing root access to G2, also have not found an exploit in this firmware, most likely because LG upgrade its security-related features to block any root Attempts.

UPDATE!! Easy method for official Android 4.4.2 has been found by using Towel roo, read it here.

For those who are still running the stock Jelly Bean and rooted with a custom recovery, it seems you don’t have to worry about losing superuser access on KitKat, as now we have stock rooted Android 4.4.2 ROM for T-Mobile LG G2, build based on official KitKat update, so you do not need to wait for an OTA update, it also updates your radio, recovery, etc.


  • A rooted LG G2 device (T-Mobile / D801).
  • To be safe, make sure you utilize a custom recovery suggested by the dev: TWRP v2.6.3.3.
  • Get the flashable official KitKat ROM from the dev’s thread here, 1.47GB of file size.
  • And also get the flashable SuperSU from Chainfire.

Update T-Mobile LG G2 to Android 4.4.2 KitKat (D80120a) and get root access

Here is a guide that we made based on the dev’s thread on xda, you need to remember, during the flashing process, your custom recovery (TWRP) will be replaced with the stock recovery.

  1. Move the downloaded ROM and SuperSU package files to the internal SD card.
  2. Turn off your phone then boot into TWRP recovery.
  3. Once enter into TWRP main menu, tap Install button, then point to the ROM file, and swipe to flash. Flashing process takes quite a long time considering the size of the ROM is quite large. If you get an LOKI error and FAILED message, just ignore it.
  4. Perform the same steps to flash SuperSU package.
  5. After doing flashing, head to main menu and tap Wipe button then wipe dalvik and cache.
  6. Reboot and your T-Mobile LG G2 should run Android 4.4.2 KitKat and rooted now.
