Upon reassembly, I had inadvertently routed the cellular antenna cable under the speaker (next to the back of the case). I had to do a bit of backtracking to free it up, and correctly route the cable *above* the speaker so it could reach the connector on the logic board.

Worked great for me, thanks! My phone was no longer charging, and unfortunately it wasn’t just a dirty Lightning connector for me - there was a burned pin on the connector which necessitated the replacement. The only (minor) trouble I had was that upon reassembly I discovered that I routed the cellular antenna cable under the speaker - between the speaker and the back of the phone. This necessitated taking some steps backward (remove logic board again after reassembling it) to free the cable, but once done it was smooth sailing after that. I’ve since upgraded to a newer iPhone and my iPhone 5 is no longer connected to cellular service, so I cannot test cellular connection; but everything else that I’ve tested (display, digitizer, home button, headphone jack, speaker, microphone, front and back cameras, and lightning connector) all work as they should. Very satisfied!
