I upgraded to 4.2E using zektor's offline guide, but now I can't load my 8gb SDHC to play VC/Wiiware. It keeps giving me 'The SD card inserted cannot be used' . I moved some of my games to a 2gb SD and they show up fine. When I was on 4.1E the SDHC worked flawlessly. If N's reasoning for the 4.2x update was performance enhancement, then this is a shitty enhancement. I do have a NAND backup of the 4.1E setup, but I'm one of those people who would rather find out why it's not working than give up. Ive restored the backup to make sure its not the card and the SDHC works as normal, it's just on 4.2E that the problem arises.
