T-Mobile LG G5 Android Oreo Update – Changes and New Features

Earlier this month, the manufacturer started rolling out Android Oreo for the G5 users in South Korea. T-Mobile, on the other hand, has yet to make an official announcement regarding the same. However, XDA recognizer contributor/developer autoprime was able to capture the official T-Mobile LG G5 Oreo KDZ and also managed to create a TWRP flashable package for those with root.


Before you head to the instructions to install T-Mobile LG G5 Android Oreo update, let us take a quick look at the changes and new features that will accompany.

Since this new update is based on Android Oreo, it carries all the standard features including Picture-in-Picture mode, Smart Text Selection, Autofill Framework, and more. The update also focuses on bringing a faster software experience with improved performance. To add, the new 30c firmware also brings August 2018 security patches, which is good, but still a slight disappointment since many other Android phones are now getting the September patches.

It would be wise to check for the OTA notification before you install T-Mobile LG G5 Android Oreo update using this tutorial. To do so, go to the ‘Settings’ -> ‘General’ -> ‘About phone’ -> ‘Software info’.

The new T-Mobile LG G5 Oreo firmware (30c) comes with Anti-Rollback Version 01. Which means you will not be able to downgrade to an older firmware with ARB version any lower than 01.


  • Perform a full backup of your personal data. Manually flashing can often lead to data loss. We suggest that you follow our guide on how to backup Android devices.
  • Charge the LG phone to at least 60% battery level to avoid any sudden shutdowns during the upgrade process.
  • The instructions will only work for LG G5 (model: H830) on the T-Mobile carrier.
  • Download and install LG USB drivers on the PC (Very important!).
    • Connect your LG phone to the PC.
    • Go to ‘Control Panel’ > ‘Device Manager’ > ‘Ports’ and check that the phone is detected as ‘LGE Mobile USB Serial Port’.
  • Install LG UP tool on the PC (Very important!).
  • If you are going to flash the TWRP package, you must have TWRP recovery installed on the LG G5.

  8. Swipe the button on the screen to install T-Mobile LG G5 Android Oreo update.
  9. Important: Once the flashing process finishes, install the ‘’ file in the same manner.
  10. Finally, press the ‘Reboot system’ button.

Wondering why we made you install Magisk? That’s because when you simply flash the package and reboot your phone, TWRP will be replaced. To avoid that, you have to flash Magisk to modify the boot.img (kernel). On the other hand, if you do not want to keep TWRP, you can simply skip the step to flash Magisk.

When the phone boots, it shall be running Android 8.0 Oreo with all the latest features for you to enjoy. So, go ahead and explore all the new goodies that you just got on your LG device.
