回答“My iPhone 6 shows no service or searching...”I have the same problem. And, like most folks here, I have tried pretty much everything from changing the charging dock to moving the mainboard to another working frame. The phone would work for a few days then mysteriously goes into the searching mode, then eventually no service. The software is up to date; the phone has been fully and network reset so many times but the problem persists. The temporary solution I have found is that whenever the phone loses the connection, I would open the phone up and unplug the charging dock connector and wait a few minutes before reconnecting it, then the phone would work again. Not a very ideal fix but it works.
