  • We assume that you’ve followed all the requirements and download all the files.
  • Flash OxygenOS 10 or H2OS 10 or DP3 Q – any one of them.
  • Reboot to fastboot mode and make sure that the bootloader should be unlocked.
  • Next, flash the TWRP Recovery (Guide)
  • Boot into TWRP and make sure that you’re on Slot ‘A’.
  • Now, connect your device to a PC via a USB cable.
  • Unpack Mi Mix 3 MIUI 11_9.11.21 OnePlus 6T (rar) file.
  • Double click on Clean Flasher.bat file to flash. (may take 5-10 minutes)
  • Now, the device will boot into the new MIUI 11 system automatically.
  • That’s it. Enjoy!
  • You don’t have to flash anything like GApps. Just install the Magisk APK if you need root access.


DON’T install MIUI OTA. It will brick your device easily. If in case, your device is bricked, you have to use the EDL mode or fastboot mode to revert into the Stock ROM again.
