Switching between Global Firmware on a POCO X3 NFC with locked bootloader

We recommend you to use XiaomiTool V20. 7. 28, which can be downloaded here at https://www.xiaomitool.com/V2/#download

Pay attention, if the installation stuck on 5% or 90% percentage, do not remove USB and do not exit! Just wait until the process is completed. In case you see a message that unlocked bootloader is required, then try to restarting XiaomiTool software, also you can try different versions in case of this issue.

  1. Disable USB debugging on your phone.
  2. Download and install XiaomiTool, start the tool and select the corresponding region.
  3. Connect your phone to PC.
  4. Confirm the connection and find your device in XiaomiTool interface window.
  5. Your phone should reboot in fastboot mode.
  6. Once Recovery mode is opened, select “Connect With MiAssistant”.
  7. Select “Xiaomi Official Firmware” and the list of available firmware versions should start to load.
  8. Select the Global ROM from the list.
  9. You’ll see a warning that all data will be removed during the process.
  10. Firmware should start downloading.
  11. After download is finished, reboot into recovery, select “Connect with MiAssistant” and wait until the firmware is fully installed.
  12. In the end you’ll see a successful message and your phone will automatically reboot with the new ROM installed.

Second method:

Download Recovery ROM version manually, then copy downloaded archive to the folder with XiaomiTool, for ex. “C:\Xiaomi\XiaomiTool2\res\tmp”.

Open XiaomiTool and select “Local Official ROM File” and then locate the previously copied file. Installation should start.
