totally possible (tiny unfortunate tear, not easily seen)
more likely and easy (enough) solution:
re-seat the connectors
pita remove front assembly, remove cables, re-snap them back on (I like a good click, then a sort of tiny swirl push, not as much as getting fingerprinted!)
then, before you re-double sided tape that back, turn on and test (front assembly does jot have to be glued back to work); if all well, then stick it back together!
hopefully makes sense, and good luck
(and if you fail, it may be possible for the genius bar (apple store), to backup without working digitizer)
