2 days ago I got what I was told "earlier version of 770". I tried to reflash it with the latest OS (2006_3). The process was succesfull, but the OS will not load completely, and the 770 was restarting continuously. The same happened when I loaded 2006_2. Finally with 2006_1 I made it load, but the touch screen does not respond. When I got the tablet the screen was responding just fine.
I don't know what "earlier version of 770" this is, but it works with normal MMC cards. But after the reflash the devise will not power on if the cart is inserted. So I took it off, but the touch screen still does not respond.
Is there something I can do to make it work?

p.s. I have other Nokia 770 which is working perfectly fine. This one is just for testing.
