my friend gave me his sd card to put the necessary files so he can upgrade to 4.0 (homebrew way via nintendo update). he knows how to install the hbc via twilight, but he doesnt know which ios/cios files to use. i have the majority, if not all, the ios/cios files on my pc since i started softmodding my console, but i dont remember whats required anymore either. i have all the files to upgrade to 4.0 (ie patched ios60, 1.3 wad manager, preloader .29, ios downgrader) since i just upgraded a couple days ago, but what ios/cios do i need so he can run the gamma loader and usb loader, if i need any at all since he'll be upgrading? thanks in advance.
