I wanted to revert back to miui 10 , so i flashed the fastboot rom via miflash tool. But it locked my bootloader. Now when i try to unlock the bootloader again from the same mi account on my redmi note 4. I get this error in chinese which roughly translates to “ UNABLE TO UNLOCK WHEN THE PHONE IS NOT USED FOR SPECIFIED TIME”
Like how much time i have to wait? I have unlock permissions and have unlocked my phone a momth ago.
