I’m glad to welcome all Mi A1 owners here! This post is completely dedicated to Xiaomi Mi A1 unofficial firmware and custom ROMs. I really hope that you’ll find here all required information, download links and installation guides. Let’s also continue with discussion in the comments below. Feel free to share any ROMs that we’ve unfairly missed and tell us what is the best ROM in your opinion.
Latest Custom Android ROMs for Mi A1 (tissot, tissot_sprout)
dotOS is a custom ROM which was developed to provide the maximum performance and stability. Everything about this ROM is perfect and every small detail is polished. This ROM version is pretty similar with AospExtended.
Here are a few thing which are required before you’ll start flashing any custom ROM. Before start I will highly recommend you to disable all pin-codes, graphic keys and fingerprint locks. Pay attention, that by installing any custom ROM version on your phone, you take all responsibility for any possible issues!
Next you’ll need to download and move to phone internal memory and internal SD card:
In TWRP go to “Wipe” > “Advanced Wipe” > Select “Dalvik” and “System” partitions. Swipe right to confirm.
Go back to main menu, tap on “Install” and select ROM .zip archive. Press “Add more Zips” and select twrp-3.2.1-2-installer-tissot.zip.
Swipe right to confirm installation.
Go back to TWRP main menu and tap on “Reboot / Recovery”.
Go to “Install” menu and select Gapps (ARM64, Android 8.1), press “Add more Zips” and add “Magisk.zip”.
Swipe right to confirm, then reboot into system.
How to enable Ok, Google on Xiaomi Mi A1 Custom ROM
Here’s a short step-by-step tutorial on how you can install Google Play app on Mi A1 with Custom ROM installed. If you already have “Google” app installed, then delete the installed app completely (you can use Sd Maid application for removal).
Download Google.zip, extract and copy files to “/system/app”.
Set up required permissions for “Google” folder – 755, and for Google.apk – 644.
Reboot your device.
If the apps crashes, go to the “Google” folder and manually install the .apk file.
