X Neo unlock bootloader

Hi!
I want to unlock X Neo globals bootloader, but it not working.
I set the oem unlock in developer options, than reboot to bootloader.
There I try both
fastboot flashing unlock
fastboot flashing unlock_critical
On the new “window” I accept the risk, than the tablet make an hardreset, but it is still locked

Same problem

Flash chinese stock firmware first and unlock bootloader using that, you can’t unlock using global firmware

So this is a bug, what must be corrected. (And if it is working with the chinese one, must probably not a big work)

Agree, it can be fixed but not sure if it will be a priority.

Chinese stock firmware is uncomfortable in Europe.   Waiting for decision.
