OEM stands for Original Equipment Manufacturer. This is the company that made your phone or tablet and it’s usually the same company that sells you a service warranty. When you buy an Android phone, you can go to the Google Play Store and download a variety of apps, but some programs are not available to download unless the device is unlocked. Unlocking your phone in this sense means to remove restrictions on what can be downloaded.

What is OEM Unlock?

OEM unlock is a setting that allows you to unlock the bootloader of your Android device. This is necessary if you want to root your device, or install a custom recovery or ROM.

Some manufacturers lock the bootloader of their devices in order to make sure that only their software can be used on the device. This can be frustrating for power users who want to customize their devices.

Luckily, most manufacturers allow you to unlock the bootloader of your device if you request it. In some cases, you may need to provide them with your IMEI number or other information. Once you have unlocked the bootloader, you can follow our guides to rooting and installing custom ROMs.
