I bought an old xbox 360 falcon that had been apparently "rgh'ed". But I suspect it is a JTAG due to it booting instantly. I decided to update it from 16203 to 16537, dumped the current glitched NAND got the CPU key (which I checked four times to ensure it was correct) and put it into xeBuild. In xeBuild, it stated that it was an RGH 1 console so I decided to go with it and flashed it onto the xbox using simple NAND flasher.
It did not state any bad blocks and it came up with a smiley face after the process was completed I then shut the xbox down (manually by turning off the switch because it froze when I clicked turn off console). Just as a note, I forgot to wait 30 seconds before turning it back on. Anyway, at first when I turned it on, it was green but just did not boot up and I left it like this for about 10 minutes. At first when I turned it on the was a loud fan noise. I then restarted it (manually) and the 1st and 3rd lights turned on red. I proceeded to get the secondary code and found out that it was 0023. People have stated that it may be because of a short but do you think it could be a bad NAND flash? I have a copy of the 16203 NAND which was working fine and the original non glitched NAND that the seller gave me.
