Daewoo 7" Tablet [Need Help!]

Need help with this tablet.

Since this is my first post, i can't provide a link but search for daewoo archive tablet and you'll get some hits for it for sale.

Is what it is (approximately) the model number is DTA-07HDAH

I can't find anything on it. I'm a friend of the owner and their son put a password on it which he forgot (he's 13). Now, we have a useless tablet that we can't access..

I've tried doing all the "normal" factory reset procedures.

1: Power up, hold down volume up and/or volume down during boot up. (doesn't do anything) one of them booted it up in "Safe Mode"
2: There is a reset button that is accessible with a pin. Pressed that, held it down all the works, nothing...
3: Searching the internet for this is near impossible...

Any help would be greatly appreciated! Thanks.
