T-Mobile LG Leon updated to Android 5.1.1 Lollipop, root possible with iRoot

When compared with other US carriers, T-Mobile is quite fast in approving a software update for their devices. That does not only apply to the flagship one, but also for mid-range phone like LG G Stylo and now the LG Leon that updated to the most recent of Lollipop – Android 5.1.1, with software version H34510e. It’s quite special as not all LG smartphones have the opportunity to run this hottest Android version.


But it seems that not all users are happy with this, especially for geek users who require superuser access on this device. The previous one-click tool now can not work to achieve root on the Android 5.1.1 for LG Leon (H345), most likely because the vulnerability that previously utilized by the tool on initial Lollipop firmware, now has been patched. This would also reduce the possibility of being able to use a custom recovery.

If you’re already apply the updates and would like to get the root LG Leon running Android 5.1.1. We recommend you to wait and see until someone expose a new method, you also should not try to use the former one-click tool, because some users find their phone soft bricked after utilize the old root method.

The Android 5.1 brings quite a lot of bug fixes and performance improvements over the initial Lollipop version, you can expect a stable software with no lags after installing the official OTA. Besides loads with the newest Android core, based on the T-Mobile support site, the Wi-Fi calling feature and battery life have also improved.

Update: New method has been found to root the T-Mobile LG Leon runs Android 5.1.1. However, we need to downgrade the phone’s software to version H34510d. We Realize that this software version (10d) is not the newest one, but this version also has the latest Lollipop (5.1.1) identical to OTA-released software (10e). Thanks to Yazuken1 – an Xda member who found this method and share it.
Here’s an overview on how to prepare it and execute it:

  1. Get the H34510d KDZ (stock firmware) file.
  2. Grab the LG FLashtool 2014 and also the USB device drivers.
  3. Flash the 10d firmware with flashtool.
  4. When the flashing’s done, download iRoot utility and install it on your computer.
  5. Run iRoot desktop app, connect the phone then start rooting procedure.
  6. Once rooting completed, you should notice a new app installed, Kinguser. It’s a superuser management app, you can also replace it with SuperSU.

For complete step by step and the required files, read the Yazuken1’s post on xda.

    I have a brand new LG Leon LTE through T-Mobile. I rooted it with the LG Root Script v1.2 from XDA. Everything seems to be working as planned. But for the past week T-Mobile has been sending me the upgrade to 5.1.1. Every time I recieve it I try to let it install but it fail with an error. It doesn’t give any error code, just a dead driod laying there and text under him saying ‘error’.

      As far as I know, you can’t update rooted device via official OTA, you need to restore to stock.
      And also, a custom recovery could break OTA update installation.
