When removing the P2 tiny screws from the antenna assembly, make sure you press firmly and twist very slowly first, in order to avoid stripping your P2 driver, which can happen very easily. We've lost a couple to this already, and we use them to open iPhones too, so take care of them! Also if you break your P2 tip in the middle of this job and you have none other, you're literally SCREWED! hahaha :)
