I have a Proscan PLT7777 and I flashed the firmware from the Curtis website, but now the touch screen will not work. I read somewhere on a different sight about changing some code in the firmware update to match the touch screen decoder chip in my tablet. How do I figure out which decoder chip is in my tablet? I have another working Proscan PLT 7777 that maybe I could get the info from, but don't know where to look.

It also says MID710-K-main ver.1.0 on the motherboard

Any advice would be greatly appreciated, thanks
