I've come across cases like these before and usually installing a custom firmware fixes them right up. Unfortunately, this may not work as it isn't always a 100% fix.
Like I said its a Craig model-cmp738b
If installing custom firmware doesn't do the trick do you know of any other tricks that may get the job done? They also reported that they have tried the reset button combinations with no avail.
I haven't actually received the tablets yet but when I do I'll keep you updated. I'd just like some extra plans to fall back on just in case mine dont work.
So... Any ideas?
