1 - 2 hours
A friend sent this to me to fix a digitizer that was cracked/shattered in one corner.
The repair went much better than I expected, but it looks like it had been repaired at least once before. There was a little bit of debris stuck to the adhesive beneath the digitizer screen in places.
It went back together and everything worked like it should. The repair guide helped a lot.
I used a fresh/clean razor blade from a construction knife to remove as much of the old adhesive as I could to get a clean surface for the new adhesive.
