I don't believe there is a way to abandon a quest if I am wrong I hope someone can tell me how quickly.

The reason I need this so badly is because I've aligned myself with the Brotherhood of Steel, after getting through a certain period in the main story line I had to abandon all hope with against the Institute. When I did this it didn't abandon all my Institute quest. I am now at a point in the quest where I will get teleported back out of the zone I'm suppose to go and can't continue with the quest because I can never reach the next checkpoint since its in a "area off the map" so to speak.

I've had this issue for a couple weeks now hoping that patches would fix this, and nothing.

Now I've read somewhere that the fix for this issue is to go WAYYYYYYYYYYY back into my save files and continue at a period and basically do the quest that it didn't abandon and then continue on.

That's hours of gameplay lost because of the inability to abandon a quest.

Sorry needed to vent
