How to keep root on T-Mobile LG G Flex running Android 4.4.2 KitKat (D95920h)

Finally T-Mobile LG G Flex (D959) has received an official update to Android 4.4.2 (KitKat) with D95920h software version, a bit late compared to the other carrier. The 20h update is the long-awaited update by its users who wish to experience the latest and greatest Android OS at the moment. But hold out, especially for rooted G Flex users, because until now there’s no working method to root T-Mobile LG G Flex on Kitkat running D95920h software version, the former IOroot method also isn’t able to provide superuser access when you on Android 4.4.2.


The 20h update not only gives you the latest Android 4.4.2, but also new features like KnockCode, which lets you bypass the lock screen altogether. LG also claims that the software is now more stable than ever, and you can expect to get better battery life with this new update.

Fortunately, there is an a dev from xda – D-FUSE, who built D95920h stock rooted ROM for TMO LG G Flex. It’s the only method that is currently able to provide this smartphone superuser privileges. Since this is a stock KitKat firmware, then after flash it, your phone will lose ability to install a custom recovery (CWM or TWRP).

The following is the requirements and step-by-step how to keep root on T-Mobile G Flex running KitKat.

  • T-Mobile variants of LG G Flex (D959) running Jelly Bean firmware. For those who are already upgrading to Android 4.4.2 via OTA, then you must first downgrade to JB.
  • Custom recovery (CWM or TWRP) installed.
  • Freedom Flex App (optional), it will help you install custom recovery and let you boot into recovery mode.
  • Get the flashable stock rooted KitKat ROM from DFUSE’ thread on xda.
  • More than 60% of battery life.

Keep root on T-Mobile LG G Flex Android 4.4.2 KitKat (20h)

  1. Put the stock rooted ROM into the phone’s internal storage
  2. Reboot into recovery mode, you can use any method to do so. But Freedom Flex app can make it easier.
  3. Perform a Nandroid backup, however, it’s optional.
  4. Wipe everything from recovery, but do not wipe the whole internal storage.
  5. Now flash the stock rooted KitKat ROM by DFUSE. Flashing process will take quite a while, so remain calm.
  6. Once flashing done, wipe Dalvik cache.
  7. Next, reboot system.

Let it take the first boot, it might be a little longer than usual because the phone needs to re-setting its software for the first time.
