Guide on how to unlock the bootloader on your Samsung phone if you have not already

WARNING: YOU WILL LOOSE ALL OF YOUR DATA FROM DOING THIS.

IF YOU WOULD LIKE TO BACKUP ALL YOUR DATA USE Samsung Smart Switch PC

Enable Developer Options

  • Firstly, Open settings
  • Then, select About Phone, then hit the Software information tab.
  • Next, tap on the Build Number 7 times to activate developer mode on your device.

Enable OEM Unlocking

  • Go back to the Settings screen, scroll down and tap on Developer Options.
  • Now, find and turn on the switch beside Enable OEM unlocking.
  • A confirmation prompt will come up, press Enable.

Unlocking the phone

Power off the phone, then hold down the Volume Up + Volume Down buttons simultaneously while connected to a PC via USB.

Once a blue screen appears, hold volume up for about 3 seconds.

Press volume up again to confirm and then you're done.

Your device should reset after this and boot back into stock.

1. Restock your device

Firstly, Please flash the latest stock Bootloader (BL) and Modem (CP) on your device with Odin3. If you are unsure as to where you can get your stock firmware from, we recommend Samfw.

Be sure to flash the Odinpack for your device in the USERDATA slot

Tip: to save time, turn off Auto Reboot in the options tab in Odin. Once Odin says Pass carry on to the next step.

2. Reboot to TWRP

While the phone is still connected to the computer (and on Download mode), hold the Bixby + Power + Volume Down buttons at the same time. After the screen goes black carry on holding Bixby and Power but instead of Volume Down hold Volume Up instead.

3. Prepare for flashing

Now that you are in TWRP, navigate to the wipe button, then press format data.
