OT: Contixo android device

[Mike Bonner]

Hey all, I was given an android device. A Contixo kids tablet.  The owner
things there is a hardware issue (white screen, touch works, sounds work,
but can't see anything.)  I suspect a horked update has caused issues.

Since I can't get to any settings (on purpose)  does anyone know of a way
to use ADB to force a factory reset? Assuming of course that I can't go in
and turn on the developer options..

Any and all suggestions welcome.  I'd really like to get it working again
so i can give it back.
