After 4 hours of working on my iPhone 8 Plus, I finally finished replacing the screen and housing but, I noticed that the charging connector was a only connecting to the logic board on one side, I got the other charging port that came with the housing and the same happened. How can I fix this without changing the whole logic board?
Try doing these: Try using a USB Ammeter, and check if the iPhone draws more than 0.5A, if it doesn’t draw more than 0.5A then the charging connector is not properly plugged into the logic boardTry putting it to DFU Mode or Recovery mode, then connect it to a computer with 3uTools or iTunes.Try turning on the phone then connect it to a computer with 3uTools and check if it sees the iPhone. If none of the above works then: A plug or connector might not be plugged or seated properly.The connector might be dirty, causing poor connection.The Lightning Connector Assembly might got damaged.The logic board might got damaged From my experience, a connector might look like it is connected, but sometimes its not seated or plugged-in properly. Try checking if a connector is completely plugged by lightly pulling the plug (as if your trying to disconnect it) using a pry tool or fingernails. If the plug easily disconnects, then it was not plugged properly. Also try closely looking at the connector if it is completely flat and you don’t see any contacts or gold traces.
