After 6 hours of futzing around, it is done. And I can charge my phone again... But I just want to point out that an operation that literally takes out almost every component in the phone, then puts it all back in again is more than "moderate difficulty". It's difficult. There doesn't seem to be much more out there that's worse than this procedure, as far as invasiveness is concerned.

Got caught up with things not fitting properly while putting back together. Just remember: don't force anything. Just keep looking to see what's caught or if you've got it slightly improperly positioned.
