i installed morden's audio package v3 on a friend's xbox (mechassault version) yesterday. i tried everything out and it worked like a charm. today he told me, when he presses the "standard button combo" (hope you know what i mean this time), he get's the service screen with error code 21. i confirmed that and had to reinstall the audio exploit with the mechassault-exploit to make it work again. does anyone know what happened? did he turn the xbox off at the wrong time? i hope that won't happen again, because he does not have an exploitable version of mechassault and i have to help him out every time...
