Amazing! Bro
But What do you mean by saying use it at you risk.What is the risk what problem can it bring up if I use it tell me so that I can take the decide to take a risk or not
Well, the risk is basically bricking your mi band!
by brick your device means that if you flash an incorrect file, you device will stop working. But resources/themes don't usually brick device until the developer has messed with the header.json file.
And for this theme, i think there must not be any problem as many people have used it including me but make sure that you flash the correct resource version with the respective firmware and yes, do everything at your own risk ?
