This is exactly what happened to my Linx 7 tablet, I did a reset a few days ago, which fixed the camera, after loading the linx drivers only partially worked for me and then stopped.
I cleaned the tablet up got rid of the windowsold folder, which was tough, eventually used CC! just to maximise the disc space. So I thought I was all set to start to set it up, but then I get the linx logo and reset, then nothing. I can see when I put my finger on the screen there is a small dot moving under it, so the screen is partially active.
I've read on other sites that this might be a drive problem. I'm also wondering whether the system was accessing the old system folders in the old installation in some way? If this is a driver problem, which is strange as I had several successful boots with the reset, is there any option to boot into a safe mode? Is there a combination of button that can be pressed? Or is that it?
