What is OEM Unlock in Android Devices?


OEM is the acronym for “Original Equipment Manufacturer”. It is also called “Jailbreaking” sometimes.

OEM unlocking is the process in which the unlock ability flag is set to 1 instead of 0, of your device. Generally, this is locked by the original manufacturing company, so the name given to it is OEM Unlocking.

The bootloader is locked by the manufacturer so that there shouldn’t be any unauthorized access to your device which we will discuss next.
