How do I fix bugged quests on consoles?

I know that PC has console to fix their bugged quests, but is there a way to fix bugged quests on the 360 or for that matter, the PS3?

My bug is I got a companion quest from Falkas to intimidate someone in Markarth. I didn't do it right away, got sidetracked with other things in the game, and finally went and completed the quest. The quest now says "Return to Falkas" and adds a marker over him. He doesn't allow me to complete the quest, he says "aren't you running a job for Vilkas? Come to me when you finished that."

I'm going to assume that I'm SOL since the 360 doesn't have a console to run commands from.

EDIT

It seems as though I had another quest from Vilkas where I had to retrieve a Steel Dagger from Southfringe Sanctum. I completed that quest and was able to complete the quest for Falkas.

Solution 1:

The Xbox is a closed system. Your PC is an open system. The Xbox is centered around the experience and Microsoft / Bethesda control the content available to you. This is not the case with PCs. There is no console option for the Xbox.

One strategy to deal with bugs is to load a previous safe point.
