Thanks for the quick replies!
I tried using another SD card and voila! I feel like a bit of an eejit... I/O error is pretty obvious even for a non-coder!
I had used the original SD for ages with no problems so didn't even think about that being the problem.
Cheers guys! :)
I hope someone can help with this...
I bought 2 pandoras, 1 for me and another for a friend. They both worked fine until 1 decided to not boot into either GUI.
I initially thought it was the brightness problem detailed in another thread but having tried everything suggested there the problem...
