Glad to see you got it.
I have added how to downgrade to 3.55, in my guide. Since a lot have asked. There is lots of info about how to, but I guess I should of had it in there.
If you followed METHOD 1 OR 2, Do Not Continue. You are Done. Or if you want to downgrade to 3.55, you can install CEX_DOWNGRADER_PS3UPDAT.PUP, and continue with Part 2 Qa Flag.
