quite easy to do unstall the currect softmod then install the new soft mod but only do this if you have your ms dash backed up when you first softmoded your xbox
u can do this if u have your linux files in your xbox hopefully u didn't delete it...and that u backed up you MS and epprom if u didnt shame on u..and also the game u used to install the soft mods...GO to the mod screen u know when it says stuff like create ms backup and mod backup and stuff like that [bold]pick Uninstall Soft mods[/bold] and if u backed up your erppom and MS then you should have a ummoded xbox cheers
