Charging port, taptonic etc not working after housing repalcement

You should definitely be testing your parts before installing them—check your spare charge port by plugging into the logic board without installing. This would have been a good idea to do with your replacement charge port that you already installed. Replacement parts are notoriously bad out of the box, and original parts are easy to damage during transfer—-so always test first.

If you have no dock functions at all, no charging, no headphones, no bottom microphone then you have a few possible faults—MOST likely would be damage to the charge port connector on the logic board so that you can’t get a solid connection due to the plastic being misshapen. Look at it very closely with magnification to see if the charge port connector looks damaged.
