Update: it seems that USB connection doesn't working , only charging
I can't even transfer my files...
Update 2: the problem was the cable, now it works
I have the same problem. I tried to do the jump from miui v5 to v7.
I downloaded a fastboot rom version, and tried a flash_all. Remote: data too large error
so i tried with mi pc suite, stable rom. It flash correctly, and miui boot great.
but there's no way with fastboot, i need to flash that...
