3 - 7 Minuten
The screen was cracked and glass falling out, still worked fine though.
It was so easy, ridiculously easy!! Only took about 10 minutes, and that was with me being super cautious. Nothing exploded, no rogue ravens or anything. Seems a lot of people were having problems with putting it back together, but I just slid the flex cable back in and snapped the little black tab down.
Takes a bit to get the screen halves apart, be careful.
