I have had my dual nand RGH 360 for about a year now and has been working flawlessly. I havent used the RGH mode for a while and tonight selected the RGH Nand to use. Upon bootup after a few seconds i got a grey screen with white writing and i think an error code of E71, i turned the 360 off and back on again at which point the internal fan was really loud and nothing happen on the 360 so i turned it off again, left it for about a minute and now when i try and turn the 360 on i get the power on audio sound (ding) but no light comes on on the 360. If i turn back to retail nand mode the 360 works fine any ideas what up with the RGH nand side of things??
