Hi.
I woke up 1 morning after no problems with my jtag for over a year, and it would not boot upafter 100 or soo attempts i get a e78 error occasionally if anything at all usually just black screen...
I bought my jtag over a year ago and can longer get in contact with seller.. I have CD with original NAND but dont know how to reflash and get this thing back up and running...

Thanks
Tony
