Here’s the obligatory disclaimer and warning:

• Unlocking the bootloader will erase all the data on your tab, including all the data that’s on the internal storage. So, make sure that you have taken a complete backup of all your important data.
• Flashing a custom binary (such as Magisk patched TAR in this guide) will trip the KNOX counter. Your device’s official warranty will be void once KNOX is tripped.
• You will not be able to use apps and services like Secure Folder, Samsung Pass, and anything that relies on KNOX.
• Although I have tried this on my Root Samsung and can confirm that this works, I will not take any responsibility of any bricked/toasted devices. Make sure that you fully understand what you’re doing and accept the consequences if anything goes wrong.
• If you do land your tablet in trouble, feel free to ask, I shall try my best to help.

Unlock Bootloader for Samsung Z Fold3 SM-F926B

1: Enable OEM Unlocking galaxy z fold 3 unlock bootloader

1. 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.
2. 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

1. 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‘.
   
2. Your tab should now prompt you with a confirmation screen, so press the Volume Up key to confirm and unlock the bootloader.
   
3. Your Samsung Z Fold3 SM-F926B  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).
