iPhone 4S wifi greyed out/ no signal after button replacement

Hello

My iPhone had a broken Power button, which I replaced.

But after I opened the iPhone and fixed the button, the iPhone shows most of the time a greyed out wifi and it keeps showing "Searching" and it does not recognize the SIM card.

Now I replaced the wifi antenna but this didn't fix it.

The problem must be on the logicboard.

How can I try to fix it (reflow etc?)

Which part of the logicboard is faulty?

Thanks in advance for your help.

Answer this question I have this problem too

Is this a good question?

Does the device pick up a phone signal? If not, your problem could be related to your baseband. It controls your WiFi, Bluetooth and phone signal. What baseband are you on? Check by going to Settings>General>About>Modem Firmware.
