There are this variants of x551 16+1 that came pre loaded with lolipop and their bootloaders are locked and no custom recovery can boot.
I have the phone oem unlocking is activated but when you restart the phone it automatically gets deactivated and so you can't unlock it via fastboot
When you try the volume up and down freezes and you can't confirm the unlock, and this doesn't mean my volume keys are faulty
I'd appreciate if I get the way to disable auto disable of oem unlocking
