Hello, thanks I want to do that. A question, is this the order in which I can realize your advice:
Step 1: Flash custom English firmware 1.3.0.8 with Gadgetbridge
Step 2: Unpair und remove Gadgetbridge (in Gadgetbridge you push delete for deleting the band from the app. Remove app Gadgetbridge
Step 3: Unpair band on custom Mi Fit App dutch. Remove Mi Fit app
Step 4: install Mi Fit 3.4.6.8 (Resources version 37 are installed automatically)
Hi, I should do it this way.
Step 1: download Mi Fit 3.4.6.8.
After installing, open the Mi Fit app. It will update you Mi Band 3 to firmware 1.3.0.8 and resources to version 37.
Step 2: Connect the band with GadgetBridge (I never unpaired the band from Mi Fit and everything still works fine)
Step 3: Install the Dutch firmware. Since your band is already updated with resources 37 you don't have to install the resources again, just flash the firmware
Step 4: Delete GadgetBridge and you're fine. I also don't unpair, I just delete it and it always worked perfectly!
