Guide Unlock Bootloader & Root Galaxy Tab A7 Lite

Unlock Bootloader for Galaxy Tab A7 Lite SM-T220/ T225
1: Enable OEM Unlocking
- First, enable ‘Developer options’ by going to ‘Settings‘ > ‘About tablet‘ > ‘Software Information‘ and repeatedly tap on the ‘Build number’ section five times. If you have a lock screen security set, you will need to input your PIN/Password/Pattern when prompted.
- Once that is out of the way, go to ‘Settings‘ > ‘Developer options‘ and turn ON the toggle next to “OEM unlocking“. You will instantly be prompted to enter your PIN/Password/Pattern, so do it. Then select “Enable” to allow OEM unlocking.
2: Unlock the Bootloader
- Then while holding the Volume Up and Volume Down keys together, connect it to your computer using the USB cable. This should take you to the bootloader screen (I call it that because logically that’s what directs you to either Download Mode or Device Unlock Mode). Long-press the Volume Up key to enter the ‘Device unlock mode‘.
- Your tab should now prompt you with a confirmation screen, so press the Volume Up key to confirm and unlock the bootloader.
- Your Galaxy Tab A7 Lite SM-T220/T225 bootloader is now unlocked and it should reboot automatically. You should also see a warning message right before the Samsung splash screen, just as shown in the picture below. Don’t worry, it’s completely normal. And no, there’s no way to get rid of it (unless of course, you relock the bootloader).
