Here’s the step-by-step instruction on how to fix Xiaomi Mi3W when it is turned to brick and started to bootloop after firmware upgrade.

  2. Use “Power” button to turn off your device. As soon as screen goes black, press “Power” & volume up button at the same time.
  3. Make all the wipes (three of them: all data, user data, cache)
  4. Load in reboot – Reboot in system two.
  5. Connect device to the PC and download the required firmware (for ex: miuisu_v4.3.0_cancro_4.1.17 or 4.1.24 from miui.su), rename the file to “update”.
  6. Use “Power” button to turn off your device. Enter the recovery (power button + vol. up)
  7. Load in reboot – Reboot in system one.
