I was reading the "easiest way to start over" thread, and I'm wondering. After that's all done with, could I then downgrade to 4.2 and reinstall the right ioses and cioses and get everything to work right? USB loaders, emulators, media players, everything? As of now, mplayer freezes and so does wiimc. If I downgrade the hermes and waninkoko cioses to v4 and rev 19 respectively, they'll play some dvds, but they're really difficult to operate and tend to malfunction.
