I understand, but we are talking about exceptions here isnt it?
And may I ask what experience I'm lacking here in unofficially unlocking the bootloader? There is no definite solution to this. Each thread told to do something and all suggestions were different from each other. I was very desperate to unlock my bootloader. I tried all clean methods to unlock it. Tried each and every solution that was posted. None worked. And after that MI ended support for this device. There was no hope left other than using unofficial ways to unlock the bootloader.
