OEM Unlock on Android

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 (Yes) instead of 0 (No) of your device. Generally, this is locked by the original manufacturing company, so its name is OEM Unlocking.

The manufacturer locks the bootloader, so there shouldn’t be any unauthorized access to your device, which we will discuss next.

Booting is nothing but a process of running system image files on your device and the program that runs it is called a “bootloader.”

The process of making a bootloader to run that image is called “booting.”


Is Unlocking Bootloader Safe?

Yes, it is safe only if you are techy, as it may cause your device to break.

The only complication in the bootloader comes when it is tried to be locked again.

The process of OEM Unlocking from the manufacturer follows the standard process as and when required. As it may be the case due to software changes, the manufacturer may reject your warranty request.

So, it is recommended only if you know the process well.


Does Unlocking the Bootloader Voids My Warranty?

Yes, in some cases, unless some software complications occur while installing custom ROMs and thirty-party apps.

Some smartphone companies like Xiaomi allow it, but others don’t.
