Hello!
Currently I have FlameOS 4.5.4.1I. I try update it to newer version but every time I receive error "Firmware corrupt".
I already try to redownload firmware file. I also try different version of firmware(Flyme 5.1.5.0G, Flyme 5.1.3.0G and other). But result always the same.

What can I do to resolve the problem?
