My home button was acting up and the battery was weak.
Overall, went well.
Had some problems with reinstalling the logic board. Both issues were covered by the guide but I didn't pay close enough attention. 1. The ribbon connector for the digitizer got pinched between the LCD module and the frame. Had to remove screws, loosen the LCD and pull the connector through completely. 2. I didn't put install the top of the logic board into the slot in the frame first. As a result, I ended up cracking the tab on the board when I screwed down the standoff. Luckily I didn't destroy the board and was able to reinstall it correctly.
