How to Install Android 8.0 Custom ROM on Xiaomi Mi 3 & Mi 4

Important: As always, backup any important file stored on your device before flashing the ROM. Also, do not forget to make a system backup from TWRP recovery.

  1. Copy and save all zip files (ROM and Gapps) to your phone’s internal storage.
  2. Disconnect your phone from PC (if connected), turn it off and boot it into TWRP recovery by pressing and holding Volume Up & Power buttons together.
  3. In recovery, perform a full data wipe by selecting Wipe Data/Factory Reset, wipe Cache Partition and Dalvik Cache.
  4. Now, return to main recovery menu, choose “Install”, and flash ROM and Gapps one by one.
  5. Finally reboot your device. It will take few minutes to complete the first boot. Troubleshooting: If you have got error while flashing the ROM, go to TWRP, select mount and unmount system. Then mount system again. Now, go to Advanced /File manager /system/bin/devicecheck.sh and tap to chmod. Repeat the ROM installation again without wiping anything.
