time 7 minutes read

Do you want to unlock bootloader on your Android devices? Do you know what OEM unlocking is? Should you enable it on your Android device? This restricted unlocking feature is quite a handful if you are a tech enthusiast and want to try innovative things, like unlocking or rooting the phone. 

In this article, we will shed some light on what OEM unlocking is and how to enable OEM unlock on your phone. Let’s have a look.

Part 1: What Does OEM Unlocking Mean?

OEM is “Original Equipment Manufacturer” and refers to the company that originally manufactured an Android phone, its software, and hardware. The OEM unlocking process unlocked this originally built software security by the manufacturer and enables factory access that you won’t usually have. In this way, you can get more access to your device.

To understand it deeply, when you power an Android device, it boots up using bootloader software. The bootloader loads the operating system and gets all the phone’s components up and running. Most manufacturers keep the bootloader “locked” as a security measure by default. A locked bootloader only allows the phone to run software cryptographically signed by the OEM.

Enabling OEM unlocking allows you to bypass this signature verification and unlock the bootloader completely. For example, with an unlocked bootloader, you can root the phone to access superuser permissions, flash a custom OS ROM like LineageOS, or convert your phone to a fully-fledged hacking machine.

  • Bootloader unlocking allows gamers to overclock their phone’s CPUs to get more performance from their phones using custom kernels.
  • Users can delete the bloatware and adware apps packaged within the phone’s firmware.

Cons

  • You will not receive the latest firmware updates from the manufacturer.

Part 4: No OEM Unlock in Developer Options? How to Fix?

This option is helpful for the new Samsung phones, whose OEM unlocking option is missing from the developer options. Follow the given steps to enable OEM unlock:
