How is it that bootloaders of mx4, mx4 pro, pro 5 and m2 were possible to unlock and not that of mx5? I know meizu restricts from unlocking the bootloaders but how was Pro 5 able to get it unlocked and not MX5? Can someone please explain? Is it ever possible to unlock MX5’s bootloader? Should we all remain in Flyme for the phone’s life time?
