Honor 8 Pro was one of the very best devices in its price range, right up there with the OnePlus 5. One of the many differences between the devices was the software experience. Honor is a subbrand of Huawei, and thus their smartphones run Huawei’s EMUI Android skin whereas OnePlus 5 provided a near-stock Android experience with OnePlus’ OxygenOS. If you thought you could always flash a custom ROM and went for the more aggressively priced Honor 8 Pro, you and I think alike. Unfortunately, developing an AOSP ROM for the device is perhaps more difficult owing to the entirely different chipset used. Not to mention stock Android still has nothing that can make use of dual camera sensors. So while you could install an AOSP ROM, it came with major disadvantages.
There have been a couple of AOSP custom ROMs for Honor 8 Pro before based on Android Nougat. The major problem being the camera quality, since the camera software couldn’t take advantage of the dual camera setup. When Android Oreo-based AOSP ROM came about, it had many bugs but they were soon squashed out with an update. This update not only brought stability to the ROM but also brought the stock Huawei camera app. This means you can enjoy most of the features that the dual camera sensors bring like you would with stock Huawei software. The beauty mode on the front-facing camera is an exception to this, but I don’t see why it can’t be fixed with future updates.
The ROM also supports project Treble which is perhaps a reason why the development was as fast as it was. Many variants of the Honor 8 Pro are yet to receive the official update that was promised by the end of 2017. Project Treble requires that the devices should be able to run an AOSP build of Android. Huawei may not be the fastest when it comes to Android updates, but the company is leading the way when it comes to supporting Project Treble. Huawei has brought project treble support to all its older devices through EMUI 8.0 even though that was not compulsory. This only shows that the 3rd largest smartphone maker is serious about providing updates.
For us, this means we can easily flash a system image and enjoy our stock Android just the way we like.

You can refer to those via the links below.
- Once you are on the EMUI 8.0 beta ROM, go to Settings > System > About phone and tap the build number several times to enable developer options. In the developer options, enable USB debugging.
- Connect your phone to the PC and grant USB debugging permissions on your phone when asked.
- Launch the ADB command interface and use the following command to boot your device in fastboot mode.
adb reboot bootloader
- Now flash the downloaded system image using the following command.
Replace /path/to/ with the location of your system.img file.
- Wait for the process to complete then disconnect your phone.
- Hold the Power and Volume Up button together until your phone reboots. Let go of the Power button once the phone vibrates. It should boot into stock recovery, assuming you haven’t flashed a custom recovery after installing EMUI 8.0.
