No cellular reception, wifi just fine

텍스트:

Hi guys, i posted on this matter befor but im going to start an thread on my own for better visibillity.

I got an defective iPhone 6 Plus and want to try and repair it myself. The problem is that i cant get any GSM reception. Here is what works and what i tried to resolve the problem:

All wireless connections like wifi and bluetooth are working (except but cellular ofc).

Everything else also works just fine. When i take out the sim card, it immediatelly tells me "no sim". If there is a sim installed, it either searches for reception like forever or just says no service. I also can see the imei and baseband number in settings. There are no signs of waterdamage whatsoever.

Today i replaced the upper antenna (the one with the plastic housing), the dock connector and the antenna cable connecting the dock with the logic board.

None of that worked.

Im starting to get a little desperate here :(

Does anyone have another idea which part could be broken? Is it the logicboard itself? Is there any way to further run some tests to find the source of the problem?

Maybe the simcard reader itself is damaged?

I would really appreciate some help/suggestions what to do.
