hey guys. first i'' say that i own mi9, works great - connecting to my pc and laptop, adb, and fastboot devices works excellent .
NOW - to the problem.
my friend gave me his mi9, totally stock, miui12 global. to backup his internal card and wipe clean and flash eu rom with root.
easy job i said.... hmmm..is it ??
when connecting the mi9 to my pc (tries several cables, originals, blitzwolf, front socket, rear socket, laptop) nothing..
tried to uninstall the driver and manually install,
tries enabling usb debugging and connect it via adb.. nothing (waiting for device)
same goes in bootloader.

what the hell ?? lol..

any one have any ideas ??

thanks!

Have you used the Mi Unlock PC application and waited for the timeout period?
