updateExploit:
C:\xboxdash.xbe Dashboard 4290s xodash\update.xbe renamed.
C:\bert_ate_ernie.xtf rmenhals new update.xbe font exploit.
All you need to
boot a habibi signed E:\default.xbe! (Linux loader, PBL, Evox, etc.)
Optional extra:
C:\MODxboxdash.xbe Dashboard 4290s xboxdash.xbe renamed, and Hex edited to change "fonts\" to "f0nts\" (note the zero in place of the 'o') there are 2 occurrences.
C:\f0nts\XBox Book.xtf - Dashboard 4290s original font from C:\fonts\
C:\f0nts\Xbox.xtf - Dashboard 4290s original font from C:\fonts\
The M$ Dashboard 4290 can now be reached by launching C:\MODxboxdash.xbe (via Evox, etc.) - for setting ya clock

or copying custom sound tracks, etc.
Its actually technically possible to launch the XBOX!Live console from the modded 4290 Dashboard Ive discovered it doesn't require C:\fonts\ folder! but dont or youll get banned. (at the moment
)
