49 Mi Band 3 Firmware Update
rffontenelle edited this page 3 months ago

NOTE

Our policy in the known firmware lists is to list every firmware only once, and name the first stable Mi Fit version where it can be found (version scheme A.B.C not A.B.C.D). If the a firmware can only be found in beta versions, then name the fist beta version where it can be found.

CAUTION

This feature has the potential to brick your Mi Band 3. You are doing this at your own risk.

It seems that the Mi Band 3 (non-NFC) Firmware 2.2.0.14 is a transition firmware that should be flashed before going to a newer firmware!!

Getting the firmware

Since we may not distribute the firmware, you have to do a little work. You need to find and download a Mi Fit APK file. There is an APK Mirror Web site that might help you find Mi Fit. Extract the downloaded .apk file with “unzip”, and you will find an assets/ directory containing *.fw files, among others.

Choosing the right firmware version for your Model

Device Name HW Revisions needed files
Mi Band 3 V0.18.3.2 V0.18.3.4 V0.18.3.6 V0.18.4.1 V0.18.4.3 Mili_wuhan.fw,
Mili_wuhan.res
Mi Band 3 (with NFC) V0.20.131.33 Mili_chongqing.fw
Mili_chongqing.res

Note: After flashing some firmware versions the first time coming from prior versions you have to remove the pairing in Android Bluetooth settings, then press the + button in Gadgetbridge to pair again. Do this if you have problems connecting after a firmware update, you wont lose any data. After that continue with flashing the .res file.

Installing the firmware

Copy the desired Mi Band 3 .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.

About Languages and fonts

There are two font files for the Mi Band 3, Mili_wuhan.ft (the normal, pre-installed one) and Mili_wuhan.ft.kj which is only for Japanese and Korean. In older firmware versions language set in Gadgetbridge has to match the font file (.ft.kj file for Japanese and Korean, .ft file for everything else) - else the menu text is blank and the Mi Band will ask you to update if you reconnect, which means you have to install the matching font file. This is no longer the case since at least firmware 2.3.0.6, Flashing the .ft.kj font allows to use ALL languages. Still language switching will change the available characters, even if they share the same font. For example switching to German will enable ä,ö,ü but disable all Chinese characters.
