However, if you choose to utilize TWRP backup to upgrade, the bootloader of your device won’t get updated and you can easily downgrade back to Nougat. Following are the known bugs present in the build:

  • The camera is pretty slow on the first boot and it takes considerable time to launch.
  • Switching between the front and rear camera takes a significant amount of time.
  • Google Play Store displays the device as ‘Un-certified‘ as this isn’t a final public release.

  • If you are going to follow the Method 2 (restoring from TWRP backup) then the your G4/G4 Plus device should have an unlocked bootloader and TWRP installed.
  • Also, make sure that you boot your Moto G4/G4 Plus into TWRP recovery and take a backup of your EFS [TWRP -> Backup -> Select EFS -> Swipe to Backup]. Copy the EFS to an external SD Card or on the hard drive of your PC.
