My iPhone 6 shows no service or searching...

This is an extremely common issue, I've tried all you have tried and more, the only solution i have found to fix it involves micro-soldering. You have to "rehash" the service module on the actual phone which is an absolute pain in the ass, your honestly better off putting your money towards a new phone, the only other solution i have had work is to remove/re-insert the sim card about 80 times until it picks up signal

I have a very strange experience as well. Replaced the dock connector had no problems whatsoever for almost 2 weeks, now started all over again. Yesterday no signal, no imei when typing *#06#, carrier setting disappeared. Today gave it another try, put sim-card in and had signal immediatly only odd thing, the carrier setting still missing, I can make phone calls, everything seems alright. when typing *#06# it shows imei....

Since I don't really trust it now, I wanted to hear what you'd suggest? Is it possible, that the baseband ic sometimes works and sometimes doesn't?

regards and thanks.

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.

Changing the charging dock worked like a charm!
