For 1 year and 7 months I successfully nailed putting the Nexus in my jean pocket but the day my car radiator sprang a leak and my car started steaming I compounded my bad luck by distractedly missing said jean pocket - the parking deck nailed the glass. Dang. I didn't fix the car radiator myself but I figured maybe I'd try the phone.

Unscrew size #0 screws, FAIL. Dang.
Even though I'd bought the size #00 screwdriver (pro version) half of those little guys were stuck in tight and I was just stripping them. Maybe it was just my weak code-typing forearms because I didn't manage to get them out but a friend of mine used my itty-bitty super-small flat-head screwdriver to get those guys out (I don't know the technical size for that screwdriver.)
After that the transplant of the internals from my phone over to the replacement phone's LCD went like clockwork. Turned it on and it was business as usual. Awesome.
I had a lot of fun opening my phone up and seeing what made it tick - and it was broken anyway so I didn't have too much to lose. Instead I gained a working phone and a little knowledge. Maybe I'll try my car radiator next time.
