I think mi band 3 is capable of much more than it is now so I want to create custom firmware that is nothing like the original. but for that I need to see the original code. I am a programmer so I think I would be able to but I don't know how to get to code of the firmware and compile it so I can install it. Does anyone have any suggestions on that ? I tried hexadecimal editor but it didn't work for me so I am looking for something like a source code or something and of course some way to compile it.
