I've just had the same problem on the same iPhone model. Took the same steps and replaced the dock but without any result at all. Checked the connector on the board under a microscope and it shows no damage.

Full restore didn't bring any result either.

Unfortunately I came to the conclusion that is a logic board problem, some component went bad and needs deeper diagnostic and high microsoldering repair skills.

这个答案有帮助吗?
