Amazfit Cor Firmware Update
Andreas Shimokawa edited this page 3 months ago

CAUTION

This feature has the potential to brick your Amazfit Cor! That said, this has never happened to any of the developers, but remember you’re doing this at your own risk.

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.

The Amazfit Cor requires the Mili_tempo.* files. For tested versions and known issues check below.

Installing the firmware

Copy the desired Amazfit Cor firmware and resource files as a *.res and *.fw file to your Android device and open it from any file manager on that device. The Gadgetbridge FW/App Installer activity should then be started and guide you through the installation process.

  1. Mili_tempo.fw
  2. Mili_tempo.res (The Cor will tell you when needed)

Flashing the *.fw triggers a reboot and will show a screen which will ask you to flash the .res if your version is outdated.

Note 1: Both upgrade and downgrade of firmware versions is possible.
