Xiaomi Mi5 bypass Mi Account I got an old Xiaomi Mi5 from a friend that has a Mi Account lock. 

He forgot his password so I am not able to use it because the phone is bound to his account.

Is there any chance for me to flash a new firmware on the phone and bypass the account lock? 
Do I need to unlock the bootloader first?

Thak you for your kindness!
you won't be able to unlock the bootloader without the mi account &amp; password ... &amp; without an unlocked bootloader you won't be able to do a fastboot flash
