Red hydrogen one

I bought a Red Hydrogen One from an estate sale and is locked. Apparently it has been erased but the previous owner did not delete his password.
It charges and is practically unused but I can’t get in to it to use the camera.
I erased the data and keep trying cosset up a new password but It keeps asking for the previous password before it will let me go any further.
Is there anyone who can work on them? Help!
