I just did this with my N7 13. I ordered this

1/2 the tools i found useful and 1/2 were not.

I ended up also running to Microcenter and getting this heat gun and also some fine tipped tweezers which i ended up using a lot for pulling ribbon cables and tape off.

I used this video as a guide.

Took me about an hour. Biggest pain the the ass was the removing the glass from the frame. The adhesive is strong and the glass constantly cracks and breaks. Use the heat gun a lot.

If you want to save yourself from the biggest pain in the ass you can get~~ this Screen that comes with a frame ~~ which means you dont need to buy a heat gun but still might need to get fine tweezers.

Good luck dude.

Edit* actually thats a real good deal that Riresurmort listed I'd defiantly get that.
