How to Update Huawei P9 B390 Android 7.0 Nougat

Compatibility Summary: This update will only work on devices already running a C432 based firmware. Since this is only available as a multi-file download, you might not be able to install it manually using the procedure written here.

  1. For this method, you’ll require TWRP custom recovery and an unlocked bootloader.
  2. Download the files given above and copy them to your phone’s memory (without extracting).
  3. Turn your phone off and reboot into TWRP mode by holding Vol up + Power for a few seconds.
  4. In TWRP, take a full backup of all the partitions and store it in the external microSD card.
  5. Go to Install, find the update.zip package and confirm its installation.
  6. Upon completion, go ahead and flash the remaining two zip files (cust and public data) too. Wipe the Dalvik cache after installation
  7. Finally, return to the main screen and reboot the system.
