How to Install MIUI 9 on Xiaomi MI A1 [Ported from Mi5X/Redmi 5 Plus]

MI A1 is a mid-range phone from Xiaomi that comes with Stock Android (Android One). The phone is backed up by Snapdragon 625 with 3080 mAh power backup.

The device runs on Vanilla Android 7.1.2 Nougat OS, and Google has already started rolling major system update, Oreo. Google Stock app suite handles Everything, (excluding the Camera and the IR Blaster). This may not be appealing to everyone.

The feature-rich Xiaomi’s MIUI is missing here. Since the firmware is pure Android, there are no Add-on or customizations, and Xiaomi only packs three of its app – Mi Remote, Feedback, and Mi Store. Also, the Camera App is built by Xiaomi because Google Stock Camera App does not support dual camera module.

Moreover, you will get all the goodness of stock Android with the regular security patch. Google also offers unlimited video and photo storage on Google Photos on this device.

But those who are missing MIUI on this device can now install MIUI 9 (built by XDA Developers). MIUI 9 for MI A1 is ported from Mi5X and Redmi 5 Plus.

The developer has ported Chinese Official MIUI 9 Dev 8.4.12 and MIUI Global Stable 9.5.4.0 from Mi5X and Redmi 5 Plus respectively. You can install any one of your choices.

However, the ROM is quite unstable for now and is not suitable for the daily use. The ROM is still in the cooking mode, and the stable version is yet to be released. If you are an Android enthusiast, and still you want to try out this port, we have a guide to install with download links. In that case, you need to have a TWRP recovery installed from before. If not, please do it from the guide below:

→ How to install TWRP Recovery [latest] on any Android device

[Since this is not an official firmware by Xiaomi, but a custom ROM, it requires a custom recovery. MI stock recovery can’t install this firmware because the flashable ZIP is unsigned.]

So, before starting the tutorial, I recommend you to make a full backup of your existing ROM via TWRP for a safe side.

You can try out this MIUI 9 ported ROM on your MI A1 using the tutorial below! Let’s proceed with the guide! We have covered an entire steps-by-steps tutorial with all necessary tools (download links are given below, keep reading to grab and install).
