The Xiaomi Poco F1 comes with Android 8.1 Oreo software, and yes, Xiaomi promised to bring the Pie update for this device in the Q4 of 2018. But if you can’t wait, you can choose the unofficial route to update Poco F1 to Android 9.0 Pie firmware. Thanks to the Project Treble for which this update is available.

Since this is not an official firmware by Xiaomi, you can not install this ROM using stock recovery. Your phone must have unlocked bootloader with a custom recovery like TWRP installed from before. If not, we have a complete guide for it. Check out:

Additionally, if you want to install GApps, you can flash it using TWRP Recovery. Do this right after installing the ROM (before first boot). Otherwise, you may face bootloop issues. So you need to have this TWRP installed from before. But this won’t be required to do separately in future as the developer clearly said, he will integrate GApps in the OS.

If you wish to root your Poco F1 on Android 9 Pie GSI ROM, follow this guide on How to Root Project Treble ROM using Magisk. The guide is Oreo-based, but still working on Android Pie.
