Huawei’s child company, Honor released their latest smartphone in the flagship series which was named as the Huawei Honor 9. This smartphone is also the successor to the Huawei Honor 8 which was announced by the company last year. The Huawei Honor 9 resembles the Honor 8 in every way possible as the design of the Honor 9 is same as the Honor 8. Also, there is still a dual camera setup on the back which was also seen on the Honor 8. However, the smartphone was released on Android Nougat and the latest update to Android Oreo was pending on the smartphone.

Now, we have known that the company has started to roll out the official update to Android Oreo which is based on EMUI which is a custom skin from Huawei and the latest version of EMUI along with the latest version of Android has started to reach the Huawei Honor 9 devices around the world. Talking about the latest version of EMUI, we have known that the update comes with EMUI 8 which is based on Android 8.0 Oreo and it will bring many features to the smartphone apart from all the goodness that comes with Android 8.0 Oreo.

One thing to note, however, is that the update has already been released by the company but only a few of the Huawei Honor 9 smartphones have received the update so it is possible that the update may be rolled out in patches. Thus, it would be a long time until your Huawei Honor 9 gets this update based on your current location. Also, we have known that installing this update is a little tricky task even though you have the packages so we have compiled a guide down below so that you can find it easier to follow this guide step-by-step and install Android Oreo on your Honor 9.

Also, we would like to tell you that the official update builds for all the regions are not available yet and we have only received the builds of Android Oreo for the C900 variants of the Honor 9 as well as the Chinese variants so there would be some tweaking that needs to be done in order to install Android 8.0 Oreo on the variants other than the ones that have been mentioned above.

This guide was provided by XDA recognized member, OldDroid who says that all the files that have been included in the guide apart from the update files have been compiled during the process of installation and the TWRP recovery that has been included below is not recommended to be used for daily usage.
