Getting root rights on Samsung devices isn’t easy compared to devices from other brands.

But it’s not impossible, as many developers have found that only a few steps need to be added to the usual rooting methods. And to get root rights on the Samsung A51, you must first unlock the bootloader on the Samsung Galaxy A51.

Unlocking Samsung Galaxy A51 bootloader

Unlocking the bootloader is a necessary step or you won’t be able to root your phone. By default, all phones come with a locked bootloader, unless you buy phones with unlocked status. It prohibits users from changing or writing anything on the system level in the device. So if you plan to root your phone or install custom ROMs, follow these steps.

  1. First, be sure to make a full backup of your data because unlocking the bootloader will delete all data from your phone.
  2. After a successful backup, open “Settings” on your phone.
  3. Go to “About Phone” and then press Build Number continuously until the message “You are now a developer” appears.
  4. Now go back to the main settings and go to Advanced Settings > Developer Options. If you don’t find developer options, search for developer options in the search bar.
  5. In developer settings, turn on OEM unlock and USB debugging.
  6. Turn off the phone completely. Then press Volume Up + Volume Down together and while holding both buttons, connect the phone to the PC with the USB cable.
  7. When Warning screens, release both buttons and press the Volume Up button once to enter boot mode.
  8. Once your device has booted into Download Mode, press and hold the volume up button to unlock the bootloader. It will erase all data from your phone and unlock the bootloader on Samsung A51.
  9. Now reboot your device into the system and re-enable the developer options by following the same steps as above.
  10. In the developer options, make sure OEM Unlocking is greyed out. If yes, you have successfully unlocked the bootloader on your Galaxy A51, and if not, try again in a few days.

Now that the bootloader is unlocked on the Samsung A51, you can start installing the custom recovers and rooting the phone. But before going through the steps, read the requirements.
