Update firmware on
Xiaomi Mi MIX 3

perseus

Warning: Make sure to download exact firmware for your model. You can discern your model from Settings > About phone > MIUI version (Eg: In MIUI version V13.0.6.0 SKHMIXM ‘MI’ represents your phone region, which is Global). You can also verify your Xiaomi phone at official site.

Tip: Some devices might have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar ..., fastboot flash ... you may have to try a different USB port (preferably a USB Type-A 2.0 one) or use a USB hub.

Download the required firmware for your model.
- Mi MIX 3 China - V12.0.3.0.QEECNXM
- Mi MIX 3 Global - V12.0.2.0.QEEMIXM
- Mi MIX 3 Russia - V12.0.3.0.QEERUXM

Note: The version in the settings screen of both LineageOS and the stock ROM do not reflect the new version number. Assuming every command worked and neither your computer nor the device shows an error, the firmware update was successful!
