I've installed the PS3-Addict.fr PS3A Rev 2 CFW firmware, which has built in 3.66 spoofing, and I'd like to switch back to another firmware. Only problem is, I can't stop it spoofing 3.66. Using Rebug's Spoofer, you could disable it and uninstall it. With Rebug's firmware you could do the same. I've actually tried putting Rebug's spoofer on to see if it cleared some kind of setting when I disabled/uninstall it, but no joy.

Since 3.66 is being spoofed, I can't downgrade back to another CFW as the console won't let me go backwards. The whole QA flag downgrader thing doesn't work either. Can anyone tell me how I stop this firmware spoofing itself as 3.66?
