Hello, I tried to install the French custom firmware on my mind band 3. But once I did what is said I got another update and I'm back to the official version... After that, my band was not detected on mi fit, I bind it with gadget bridge, then it's connected on mi fit but after a few hours I don't have the "no Bluetooth" sign on the band but my phone says it is not connected? And by the way, I thought it was ok so i turned the Bluetooth in invisible mode... What can I do? Thanks a lot.
