I have a Mi Band 7 Version M2129B1 with Firmware 1.27.0.4. How do I update the device? I found https://mega.nz/folder/Y4c0DZTJ#I3NBPacQlCfJGOZ5hKI5WA/folder/5ok1WaoA where you can download zip files, but the Gadgetbridge wiki says something about *.fw files. Don’t want to brick the device. Any recommendations?
Try asking in the Matrix room, as that’s the official channel where the knowledgeable people are.
