Saw this on ixtreme.net last night.
http://www.ixtreme.net/open-forum/20126-heads-up-dont-update-phat-consoles-youre-planning-rghing.htmlIf anyone has a PHAT XBox 360 console they are planning on installing the Reset Glitch Hack on - DO NOT UPDATE IT PAST DASH VERSION 13604!
The new beta dashboards have been updating every PHAT console's firmware to a CB version that makes the RGH useless on dash versions above 13604! There's absolutely no reason to believe the new dash releasing tomorrow won't do the same thing. Until a workaround is discovered, any PHAT consoles updated with the new dash released on Dec, 6 2011, will be blocked from the RGH.
This doesn't affect SLIM consoles as the RGH exploits them in a slightly different way.
Obviously if you have a Xenon console, this doesn't apply as updated ones are non-exploitable.
