Hi everybody! :)
After the precious advice of user ndt192, I managed to unlock my SKR-A0 which, until this day, seemed un-unlockable.

THIS PROCEDURE WILL WIPE YOUR PHONE MEMORY SO REMEMBER TO BACKUP EVERYTHING
TL;DR
In developer options, OEM Unlocking must be ticked (if present), then I just issued a fastboot oem unlock while in fastboot mode.
I'm on the latest OTA (29-12-18, v. G66X1812291CN00MPX).

Full Tutorial
  • Enable developer options by tapping 7+ times on Settings -> About Phone -> Build Number
  • Enable USB Debugging and OEM Unlocking (if present) in Developer Options (Settings -> Other Settings -> Advanced Settings -> Developer Options)
  • Open a terminal and issue the command adb devices
  • On the phone, allow the access from your computer on the dialog that will be shown
  • In terminal adb reboot bootloader
  • Wait for the phone to reboot in bootloader mode
  • STOP AND THINK - DID YOU BACKUP EVERYTHING?
  • Issue the command fastboot oem unlock and wait for the OKAY in the terminal window
  • Reboot your phone with fastboot reboot

Now, you will be informed that because of the unlocking your phone memory is "corrupted" (aka not decryptable anymore) so the phone needs to be wiped. Agree and wait.

Hopefully, your bootloader will be unlocked now. You can check that by returning to fastboot mode and checking that the Status is Unlocked.

If you want TWRP/root, check out this thread.

This procedure didn't seem to work until a few months ago so I don't know exactly if this procedure works only on newest Joy UI versions or not. Try it out (at your own risk).

IMPORTANT - if you can't unlock with these steps, please post here with the version of Joy UI installed and the message shown after the fastboot oem unlock command
