CAUTION
This feature has the potential to brick your Mi Band 4. You are doing this at your own risk. That being said, it did not happen to us yet.
Getting the firmware
Since we may not distribute the firmware, you have to find it elsewhere :( Mi Band 4 firmware updates were never part of Mi Fit, but are only made available via OTA updates.
Choosing the right firmware version for your Model
At least up to firmware 1.0.5.55, it is possible to use the non-NFC firmware with the NFC variant! It is also probably possible to do the other way (using NFC firmware on the non-NFC model), but we did not test that
Device Name | HW Revisions | Codename | Default Language |
---|---|---|---|
Mi Band 4 | V0.25.129.5, V0.25.130.5, V0.25.131.5 | Cinco M | Chinese |
Mi Smart Band 4 | V0.25.17.5, V0.25.18.5, V0.25.19.5 | Cinco M | English |
Mi Band 4 NFC | V0.25.131.21 | Cinco L | Chinese |
Installing the firmware
Copy the desired Mi Band 4 .fw and .res files to your Android device and open the .fw file from any file manager on that device. The Gadgetbridge firmware update activity should then be started and guide you through the installation process. Repeat with the .res file (you don't have to do this if the previous version you
flashed had exactly the same .res version).
If you get the error "Element cannot be installed" or "The file format is not supported" try a different file manager. Amaze should work.
