Sorry for the double post, I chose to post again instead of editing to bump the topic and mark it as updated on the main board.
Alright, so I followed everything, and though I ran into many bumps on the way, mostly using consaver to reassign my saves (my KV was the wrong size, and I don't have my cpu key anymore, nor are my LPT wires still soldered) but everything's up and running now, forza 3 saves nuked though, haha.
Anyway, I did notice that I do need that avatar update since none of my profile avatars are showing up. Thing is, I didn't remove the R6T3 resistor nor did I do the solder bridge. Now, I plan on popping my 360 open tomorrow anyway to reseat my CPU heatsink (RRoD is gone, but the CPU idles at 80C and the fans are constantly spinning in what seems like turbo mode), so should I wait off on the update until tomorrow night when I can protect my NAND, or is it safe to apply the update now, even with XBR 8955 on my NAND?
