thx for the reply Robinsod, tried that but for some reason my console will not boot up. I'm thinking it may have been a bad flash.
Sounds like a bad flash to me if your console will not boot and if Infectus cannot detect your nand. I would have a look at Arakons external power diagram as it explains how to provide external power to your 360 so that infectus can detect your nand. http://www.infectus.biz/forum/index.php?topic=160.0
I had the exact same issue, read the flash correctly but when I went to write it, infectus flashed some bad data. My Xbox 360 wouldn't power on and Infectus couldn't detect my nand. I read up on the external power fix and unsuccessfully flashed my 360 another 15-20 times before I found the correct 360 Nand Installation diagram that included the V wire. Without the V wire Infectus corrupted my flash, after installing it, everything worked perectly and still doeshttp://www.infectus.biz/diagrams/Xbox360_1b.JPG
I installed my Ground wire to the right of the 5V
Hope that helps
thx for the reply and thx to Uberfry's advice, I just successfully did Arakons bad flash method and I got my console to boot!!!
