Motorola is currently soak-testing Moto G4 Android Oreo update and a beta build has recently been leaked. If you’d like to test the new update, then follow the instructions below to install Android 8.1 Oreo on Moto G4/G4 Plus. You can either sideload the Soak Test OTA via stock recovery or restore the TWRP backup.
Android smartphones from Lenovo-owned Motorola aren’t the best bet when it comes to regular software updates. Most of these phones have been criticized for delayed software updates and broken promises. Talking about updates, last year Motorola publically disclosed the list of their phones that were designated to get Android Oreo update. Most of these phones including the Moto G5/G5 Plus, Moto G5S, Moto G5S Plus, Moto Z, Moto Z Play, Moto Z2 Play, and Moto X4 have already received the Android Oreo update. Motorola decided to directly jump to Android 8.1 Oreo, skipping 8.0 as the company was already behind the schedule.
However, both the Moto G4 and Moto G4 Plus were not present in the list. The phones were released back in 2016 and came with Android Marshmallow out-of-the-box. Seeing the outrage among the users, the company reconsidered its decision and is finally testing Android 8.1 Oreo on Moto G4/G4 Plus.
Updated on 13 February 2019: OTA package and TWRP Flashable zip of stable Android 8.1 Oreo for Moto G4/G4 Plus is now available. The new firmware comes with the OPJ28.111-12 build number.
Moto G4/G4 Plus Android 8.1 Oreo Update
XDA Senior Member rajatgupta1998 was able to capture the leaked Android 8.1 Oreo soak test build for the Moto G4/G4 Plus. The new software comes with OPJ28.128 build number and November 2018 security patches. The member also made TWRP Backup of the build. So users who have an unlocked bootloader with TWRP can easily restore the provided backup to install Android 8.1 Oreo on Moto G4/G4 Plus.
Since the leaked OTA updates your phone’s bootloader and modem to the newer Oreo version, you will NOT BE ABLE TO DOWNGRADE back to Nougat if you choose to sideload the OTA and will be forced to wait for the stable Oreo update. For the same reason, it is best to use the Android 8.1 Oreo TWRP Flashabe zip to upgrade. Using it will not update your Moto G4’s bootloader and thus allow you to downgrade easily, should you ever want to do it.
Now before you head on to the instructions, take a note of the bugs that have already been discovered in this update.
- The camera is slow on first boot and lags often. It also takes time to open.
- Switching between the front camera and rear camera takes some time.
- SafetyNet does not pass since this isn’t a final public release and hence Play Store shows device as “Uncertified”.
You are now aware of all the details about this update and the issues/bugs that it has. If you can overlook them, then follow the steps below on how to install Android 8.1 Oreo on Moto G4/G4 Plus using two different methods.
- Irrespective of the method you choose (Method 2 will completely wipe your phone including the internal storage), I strongly suggest you take a complete backup of all your data on the phone. We also covered a detailed tutorial on how to backup Android devices completely.
- Charge your Moto G4/G4 Plus to a sufficient battery level to avoid any sudden shutdown during the update process.
- For method 1, your phone must be on Nougat firmware with build number NPJS25.93-14-18 (Download here)or Oreo 8.1 Soak Test with build number OPJ28.111-12.
- In order to use method 2, you must have an unlocked bootloader and TWRP (You can download it here) installed on your phone.
- Important: Also, boot your Moto G4 into TWRP recovery and take a backup of your EFS (TWRP > Backup > Select EFS > Swipe to Backup). Make sure to copy the EFS backup to an external SD card or your PC.

The leaked beta build clearly indicates that the stable release is not so far now. However, nothing could be said for sure right now. Of course, the list of issues we mentioned above will first need to be fixed. Once everything is ready, the Android Oreo update will be rolled out to the users over-the-air.
