Hi all, I'm in need of your help. Basically I had the big block Jasper booting fine. I threw a backup copy of Tekken Tag Tournament 2 in to test the drive mod. It showed up, but then it asked me for an update. Well apparently this is the first game to contain the 15574 Dash update, as the console was running the newest freeboot. So I said ok to the update as it was just the avatar update. the first half of the update went fine, but when it restarted to continue the update, it said dirty disc, unable to update. Any way, now it throws e71 without the disc in the drive when I attempt to boot it, and it gives me the dirty disc error if it's in the console. Updating from usb and regular dvd have both resulted in cannot process updates errors. Really need help to sort this out. By the way, I have two matching 64mb dumps, not 512mb. Thanks
