This guide should also apply to any other recent Xiaomi phone with fastboot support.
This is an A-only device without Xiaomi's newly introduced anti-rowback (downgrade) mechanism. Originally shipped with Android 8.0 in June 2018. Supports dual-SIM VoLTE on stock firmware with Snapdragon SDM 710 SoC. available in 4/64, 6/64, 6/128. GSI images relies on the stock vendor partition to work properly. So stick to the GSI image with the same Android version as the MIUI. At this moment, May 2019, Xiaomi has released pie based firmware for this device. In the future, if you want to upgrade the system of your phone, the whole procedure described on this page will need to be performed again to avoid problems. (And search for the TWRP works with future release, in case the one on this page is outdated) Before you do anything, please BACK UP YOUR FILES!!!

- Enter
TWRPand performWIPE > FORMAT DATAandFACTORY RESET - Copy the ZIP file (MIUI 10) to
DEVICE / TWRPfrom theWindows Explorer(Drag and Drop) - Next go to
INSTALL > INSTALL ZIP, enter the directory/data/media/0/TWRP, flash ZIP file and finish by pressingSWIPE TO CONFIRM FLASH - Wait for the installation to finish (the system starts in initial MIUI screen)
Alternatively you can just extract the boot.img file from xiaomi.EU ROM zip file and flash it as the description of AOSP system image flashing.
Note: Actually this step replaces stock boot.IMG with the one from xiaomi.eu, Since GSI image doesn't boot with the stock one. And if the xiaomi.EU version doesn't match with the stock MIUI version on device (I.e. boot.IMG doesn't match other blobs), the device will kick into fastboot to force you to perform a fresh installaion of stock MIUI, or exhibiting unforseeable problems eg. touchscreen not working.
