Need some answers if possible. I have an iPhone that does not recognize if a SIM is in the phone or not. It is stuck in a searching mode. It states that it needs an update, but after hooking it up to iTunes and updating, it just goes back to saying the same thing? Any ideas?

The iPhone 7 has several design issues. The Qualcomm baseband version logic board has multiple issues that can cause “searching” or other connection issues. At this point it sounds like a hardware issue so you will need to have it looked at by an experienced micro-solderer. However, if the problem is within the baseband IC itself, it will not be repairable.
这个答案有帮助吗？
If no IMEI is displayed via dialing *#06# in dialer, modem and IMEI missing in settings general about phones those are symptoms of baseband circuit failure.
