Mi A1: All Android One ROMs and Custom ROMs

We have collected all available direct download links to grab stock Android One ROM for Xiaomi Mi A1. All links to the official stock ROM are original, untouched, and unmodified since they are hosted on Xiaomi’s cloud servers. However, if for some reasons you cannot download the file from its original location, feel free to drop a comment requesting a mirror. We will be happy to provide your with mirror links whenever asked.

We also add some of the available custom ROMs compatible with the device either with Project Treble supported or not. Custom ROMs are good for some people since it might offer better stability, awesome features, and a smoother experience. Nevertheless, it might be not so useful for other users. Therefore, please be wise when switching from stock Android One to another ROM.

Mi A1 is the first Xiaomi’s device released running Android One operating system which is claimed as the purest form of an Android mobile OS. However, there’s also some other “vanilla” Android OS that offers a pure version of the OS. The biggest advantage of using Android One compared to both MIUI ROM and Custom ROM is its direct support from Google. Yeah, that Google, the one creating, making, developing, and maintaining Android OS.

That being said, its users can enjoy regular updates with latest security patches. It is surely the biggest advantage especially for those who concern about their device security the most.

Custom ROMs

In a nutshell, an Android ROM is an operating system build that runs on your device with basic applications such as an address book, calendar, camera, etc. It’s just like MIUI. When it comes to “Custom ROM”, it is a term generally meant for not the official OEM-version of ROM. Usually, it is developed by Android geeks out there whether individuals or as a developers team.

Q: What is needed to install a custom ROM?

The first thing you will need is, of course, a phone with bootloader unlocked. You can apply for the official permission to unlock the bootloader from the Xiaomi website. We have wrapped up all the necessary steps on how to unlock a Mi A1 bootloader here. The second thing you need is custom recovery. You can use either the official TWRP Recovery or Red Wolf Recover (RWRP). This interface is needed to flash the ROM package on your phone. The last thing you will need is Google Apps (GApps). Most of the custom ROMs do not come with gapps pre-installed. In this case, you can simply use OpenGapps and flash it through TWRP as well.
