How to flash MIUI 9 ROM on Xiaomi Redmi 4X with Global ROM 8.2.10

  1. First of all you’ll need to download both ROMs – Global ROM 8.2.12 together with Global Developer 7.8.31 MIUI 9 ROM from here. Download these ROMs using your phone (recommended way) or PC and then copy downloaded .zip archives to your phone memory.
  2. Open “Updater” application and press the three dots icon at the top right corner.
  3. First select and install Global Stable 8.2.12 ROM, after updating to 8.2.12 make backup of all your data and important files (you can use Mi Account for a backup), because after flashing to the latest developer ROM all data will be deleted.

  5. Wait until installation process is completed.
  6. Don’t forget to restore your personal data from the backup!
