I have a problem with the touch screen ( no response anymore), so I upgrade my Zenithink with new firmware hopefully it works again. I have have firmware standing on from march 2012 (I have firmware included with my zenithink on a sd-card), and I upgrade to the newest firmware from august 2012, downloaded from zenithink website (version 1a). But I still have the same problem with my touchscreen. I saw in the forum that there is no other way to fix it, I think? Also I want to ask where I can see which firmware update I have on the zenithink, because I see nothing standing. Thanks for reply.
