EMUI 8.0 on Huawei Mate 9
 

EMUI 8.0 builds, based on Android 8.0 Oreo has been seeping out slowly onto Huawei and Honor devices lately. Some officially and some through beta channels. Huawei Mate 9 is one of the devices to have received a full-fledged official update to Android Oreo and EMUI 8.0. The update brings the usual Android 8.0 features such as Picture-in-Picture while EMUI 8.0 brings in a set of its own unique new features. We’ve already discussed what’s new in EMUI 8.0. This is not a post about that but about how to install the Android 8.0 Oreo-based EMUI 8.0 on Huawei Mate 9.

You should already have received the OTA. But if you haven’t, or for whatever other reasons, you want to install it manually, here’s how. The original guide was put together by mankindtw but it could get a little bit confusing if you have never done this before. So here’s our guide based on his, hopefully, a bit more elaborative.

Warning

First things first, flashing software on your phone yourself can be a bit risky. It probably won’t void your warranty but it could send you to the service center. In most cases flashing the original stock firmware almost always restores a device. Nevertheless, you must own up to it in case things do go south. DroidViews is not responsible for any damage to your phone. Proceed at your own risk.

Note

  1. Backup all of your important data – Call logs, messages, apps, everything on your internal storage. The entire slate on your phone will be wiped clean during the process.
  2. Make sure your Huawei Mate 9 has an unlocked bootloader. This is required to install the TWRP custom recovery. After the update, your device’s bootloader can be locked again.
  3. On your PC, install ADB and Fastboot along with any necessary USB drivers if you’re using a Windows PC. This is not a necessary requirement but the lack of ADB and USB drivers could potentially lead to some error later. Better safe than sorry.
  4. The firmware available for download below and the method to install them are both meant only for Huawei Mate 9 (MHA-L29/MHA-L09). Do not try it on any other device.
