How to flash Custom ROM on Mi Mix 2 with TWRP Custom Recovery

Let’s assume you’ve already unlocked bootloader and successfully installed TWRP on your Mi Mix 2 device. Now you’ve selected Custom ROM you want to try and ready to proceed with installation:

  1. Download ROM you want to flash.
    • Select and download the Google Apps (optionally).
  2. Copy downloaded ROM .zip archive and other patches and additional tools to phone internal memory.
  3. Boot into TWRP Custom Recovery to backup your data and wipe all required partitions.
    1. In TWRP main menu tap on “Backup” and proceed with system backup.
    2. Tap “Wipe” and select the following partitions: Dalvik/ART Cache, System, Cache & Data.
    3. Swipe to confirm wiping.
  4. Go back to TWRP main menu and select “Install”.
  5. Locate downloaded .zip archive and follow the instructions on screen to flash ROM files.
    1. Optionally you can install all additional files like Gapps and Magisk archives. Pay attention that if you’re going to install Gapps, you must do it before the first boot into system.
    2. If you need to have root enabled on LineageOS based ROM then install addonsu application for arm64, otherwise use any other method you can find in different sources.
  6. After ROM installation is finished, select “Reboot” > “Reboot into system” in the TWRP main menu.

If everything was done successfully you can now experience a newly installed ROM on your device! Share your opinions on which ROM you think is the best one.
