While replacing my broken screen, I probably ripped something!

[igby]

My screen broke, in many pieces, while I was removing to replace I think I broke something else! that flex thing was so glued to the glass that I teared a piece... my question is, can this possibly be related to the POWER/SLEEP, VOLUME and LOCK buttons? They are not working anymore, and even though all the circuit that connects those buttons seem to be fine, since they're not working I can only assume this is relatable.

Here's the picture, any input would be muuuuch appreciated!
