I was trying to pass from the A version to Global one and suppose i did a mistake.
I used the 2nd method as it’s said and in the terminal emulator step i wrote the correct text. However i thought that i did a mistake with a dot and rewrote it.
The phone turned black after 10 minutes and when i rebooted it, it is stuck on the screen with the Meizu logo. It’s not proceeding to the flyme boot.

Any thoughts whats wrong with it, or what could i do to save the device?
