I've done the screen before, it just plan sucks. The plastic is very brittle around the lcd.and it will break most of the time. If you need a screen and your on mdl, buy one that is original and assembled. If your on mf3 or above just pay the $200 deductible and be done, because a original screen is $200 anyways. If you want to try the loca glue route I will advise you not to. The heat gun, temp gun,uv light, will almost cost as much as a good screen, or replacement phone from assurion.
