Did this mean the manufacture use is own private key? not default one?

^^ Basically, I got the same output but for different device - ZTE Nubia Neo 5G (model: 8150N; CPU: Unisoc T820)
except being on Linux machine where $PATH differ.

The results are same for both user (in wheel group) and root.
This one's for root:

python3 -m unisoc_unlock unlock

unisoc_unlock.bundled_adb.fastboot.FastbootRemoteFailure: ("FAIL: b'Unlock bootloader fail.'", b'Unlock bootloader fail.')

FWIW the output of the fastboot devices command is:
32xxxx77 fastboot Data <<< Never seen this Data output

and there is NO fastboot screen, just the same (this time static) boot logo.

So, this is going to be quite a journey with my first ever Unisoc device. :)

Sorry if this looks like issue jacking. @AlterCreator
Feel free to move it to separate thread if needed. @patrislav1
Cheers!
