Are you talking about an actual ribbon cable (gray rubber looking flat cable) or the (sort of) gold and yellow "soft board"?
I have never had any real issues with ribbon cable getting messed up.
If you are talking about the "soft board", yeah they are pretty sensitive to bending.
When you installed it, did you make a 180 degree flat bend or did you gently loop it back over?
If you made a hard bend with it the it may very well be damaged.
I would much rather go to my grave not needing my gun, than go there wishing I had it.
