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.

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 can't dial as I can't activate the phone .

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

Soluzione Prescelta

After you have eliminated antennae or network locks as the possible culprit, searching issues on the iPhone 6 are usually related to the baseband IC. The baseband IC is very sensitive, just like the Touch IC's on the 6 Plus; it also suffers from poor quality traces and pads.

Go to your phone’s dialing keypad and dial *#06#. You should see the IMEI displayed.

If the IMEI is not displayed, the Baseband IC has to be reballed and two small copper traces (U1/V1) have to be rebuilt and solidified. This is commonly referred to as the “long jumper” solution. You can check out this answer by @teetopp (Service is "Searching" indefinitely) as it summarizes the issue really well.

Reballed baseband ic. Now I'm getting error 50. Any ideas about that ?

You're reball may not have been successful or you may have dislodged or bridged some surrounding components.
