The G series of Motorola has been one of the most successful smartphone lineups of the company. Unfortunately, most of the phones are lagging of getting the major system update from the company. The Moto G4 and G4 Plus were released back in 2016 with Android 6.0 Marshmallow. But later, both the device received Nougat update from the OEM. Despite promising an update for Android Oreo, they exclude the G4 in their Oreo update timeline. However, the company backtracked their decision now, because of the strong negative reaction of their users.

We are finally getting much closer to receive a major system update for both the device. The Moto G4 Android Oreo update is being soak tested by users, and one of the beta build has been leaked online.

Thanks to the senior XDA member rajatgupta1998 for sharing Android 8.1 Oreo build with November security patch. The build number is OPJ28.128, but keep in mind, you can’t downgrade after installing if your device bootloader is locked.

With this guide, you will be able to update your Moto G4 / G4+ to Android 8.1 Oreo firmware using sideload method. Read ahead; we have download links for all necessary files along with the OTA link. Tutorials are given below with detailed steps. If you are the first time playing with sideloading, please do read the entire article once before performing this experiment.

Moto G4 and G4 Plus Android 8.1 Oreo Soak Test

The OTA has been captured by XDA user rajatgupta1998. He also created a TWRP backup, in case you have a custom recovery installed, you can easily restore it to get the fresh Android 8.1 Oreo on your Moto G4 / G4 Plus.

But keep in mind that this is a major system update. The newer software comes with an updated bootloader and modem version. Once you install this update, you can’t get back to Nougat. So, you need to wait for the stable release from Motorola. However, if you restore the TWRP backup, it will not update your bootloader and modem. So you can easily downgrade if you want.

Spotted bugs

  1. The camera seems very slow on the first boot. It also lags sometimes.
  2. Switching between the primary camera and the secondary camera needs time.
  3. Since this is not the final build, SafetyNet is not passed yet. Therefore, Play Store shows device as “Uncertified”.

We hope these bugs will get fixed as soon as the OEM release a stable update via OTA. Now you are aware of these bugs. If you are okay with them, just follow the instruction below in order to update your device.
