So I got DVD Read Error 324. I'm using TDK DVD's that are made by Ritek, so they're supposed to be decent. As I said, I installed the safe 3.3 update and cIOS36_rev7, but it still doesn't work. I hear I need to reinstall the cIOS, but how do I do that? I heard I need to downgrade my firmware, then use IOS Downgrader, then uninstall IOS249, install the IOS again (which one?) and then install safe 3.3. Is that what I should do? How do I downgrade my firmware? Which IOS Downgrader (custom 1.2 or 1.0)? Which IOS?
