tried to update to new ios and lost my usb loader
i recently got brave and decided to try and update to "d2x cIOS v7 Installer v3.1" since a lot of the newer games dont work for me anymore. i followed the quide on this site to the T , and i thought it went well until i tryed to load usb loader and i get nothing for 10 seconds, just black followed by a stack dump screen then i says reloading in 5 seconds a just freezes.
what did i do to it, and is there anyway to undo, or would i need the original wad files that i no doubt overwrote.
