Since then I've gone through the instructions in that thread several times and even posted there with no luck. I've restored to stock every way I can find including the 8 failed boots method and have tried damn near everything else I can find. I've swapped out drivers on the PC, reinstalled the Android SDK more than once and have verified this same thing occurs on multiple PCs and with multiple cables. I will say that the one time I got it to work was by rolling the NC all the way back to 1.1.0 but if I update after that it stops working again.
As it stands now my NC is completely stock as far as I can tell it just won't let me transfer files to it. If I transfer a book to the SD Card on the PC and then plug it into the NC and try to open it all I get is a blank white screen with a small black arrow at the top and the NC becomes unresponsive.
Is there some change I'm missing that would cause this or anything else I might have done? Please offer any help you can think as I've tried everything I can find. Also, sorry for the wall of text.
