the phone can be fixed but it need a lots of time
 
I am ready to give the time for this I purchased the mobile here in Qatar
The problem is probably the following:
Your device is a CN version with the bootloader unlocked because a Global ROM is installed.
If you lock the bootloader on a CN version with a ROM other than CN, the device is bricked.
solution provided that:
(with a little luck the options necessary for unlocking have remained activated)
USB debugging is enabled and the device is linked to your Xiaomi account.
Use Miunlock to unlock the bootloader.


If debugging is not enabled and the device is linked to your account (not free):
