Fastboot Unlock

VAR-SOM-MX6 - Android Nougat - Fastboot unlock

OEM unlocking via Fastboot

If you are using the user debug build, it behaves like a standard Android device and says device is locked.
You may need to unlock the device by following below steps:

• Settings => System => About Tablet => Build number
• Keep on tapping until you see a prompt that says "You are now a developer!"
• Settings => System => Advanced => Deveoper options => OEM unlocking
• Reboot to bootloader via

$ adb reboot bootloader

or on the Serial terminal

# reboot bootloader

• Type "fastboot 0" in the U-Boot command line
• Run "sudo `which fastboot` oem unlock" from the Host PC
• Wait until the unlock process is complete

Now you should have your device OEM unlocked, and from now onwards you can flash your custom-built AOSP images generated from your Android build.
