1 iPhone 6 no service/ searching with or without SIM
So I'm very new in microsoldering and learning stuff just from YouTube/ ifixit forum.
I bought an iPhone 6 (64gb) which didn't charge. Replaced TriStar , turned on, it was charging, everything works.
As this was used iPhone I did factory reset. Since then I can't activate the iPhone , it says servers are down.
It is not showing NO SIM when there is no SIM card, and just keeps searching/ no service. I tried to restore it via iTunes , but after the update I get a message on iTunes that it failed to restore because iTunes was unable to read activation data, and I have to ensure SIM card is correctly in the phone.
I did replace every antenna in the phone, tried different dock with no luck.
I'm stuck here.
ANY help will be more than appreciated. Thank you
Edit:
After couple of hard resets and slight smack against the desk it ask for a SIM card during the activation process, I entered the pin code but it keep saying Unlocking please wait . But it never did.
Tried to change for SIM without lock but it keeps asking me for pin code. Like it read the SIM card for a second and then got stuck on it.
Ist dies eine gute Frage?

is the phone unlocked to all networks or on a certain network as the code it is maybe asking for is the unlocking code for the phone to accept any sim

No this is unlocked for all networks.As I said to me it looks like it recognise the SIM for a nano second at the very beginning of the boot and then it lost connection to it or something. I can't unlock the SIM / can't get service, iTunes does say there is no SIM, I just don't get it .

I have this issue too, here is how did i fix it and what happened after: mine is iphone 7, it all happened one day there is an error message pop up : "Cellular Update Failed - Your iPhone cannot make and receive calls or access cellular data until it has been updated "; i thought iOS update will fix it which it did ( like the original post saying, you need to be extremely careful when factory reset it, as you might facing phone can't be activated, i guess i was lucky, I only tried like 5 times ... somehow it gets activated ) ... same message pop up again after couple days ... so, according to above , i think i can make a logical assumption: it's the hardware issue, the chips in charge of controlling cellular signal/data is having problems ( somehow it lost its firmware at certain condition , i guess might be high temperature or sudden heavy vibration ) ...anyway, that chip is basically broken ...
When iOS has new update, it is your chance to bring the phone back to work... but only for couple days.

It’s not a broken chip it could be baseband ic needs reballed or the baseband power ic is going bad
