Cannot factory reset the locked Android OS (Hi10)

Hello!

I have a problem where I cannot factory reset the locked Android OS. I’ve managed to reset the Windows version as well as changed language but I cannot get the android terminal up by pressing volume up/down and the power button.

My question is, how can I factory reset the password-protected Android OS without actually accessing the terminal? Is there another way to access the android terminal?

Thanks in advance,

Daniel.
