Desperately need help with da:o bug

[Revan1993]

I'm stuck in the brecilan ruins. How? Well, if you check the walktrough, you'll see that you have to complete the ritual at #7, so you can open the door to #8, however, for some reason I suddenly got a cutscene of a shade, fought it, and that heppened before I could do the ritual. Now hte door back to #7 won't open. Is there perhaps a cheat system for PS3 that lets me open the door, or another solution. I'd be very grateful if someone knows, cause my last backup save was at Ostagr so I lose hours of progress if there's no solution

Well, to be honest.... The Elven Ritual isn't exactly part of the Main Quest.

Spoiler

It's only necessary if you want the complete set of Juggernaut Armor

(End Spoiler) AFAIK, no cheats on the Consoles.
