thank you very much, works like a charm. @sica1 , you should try this to. only unlock bootloader again using mi unlock tool and thats it, phone will reboot to miui v9.Solved. I send the request to unlock the bootloader of my device (this locked again when i update to miui9). when i received the autorizathion y unlock my phone and reboot and now i have miui 9 in my phone.
Unlock bootloader with mi unlock and the device must start. I try flash with fastboot whit my bootloader locked and the program throw me the same error. Unlock the bootloader here http://en.miui.com/unlock/I tried flash with mi flash but give me this error:remote:critical partition flashing is not allowed.
What can I do?
