My phone has no service does searching for signal tried other sims still an issue did a factory reset I wasnt signed into my icloud account when I reset it but now phone is bricked will not activate what do I do?

Not much you can do, since all points to a hardware issue that needs a microsoldering repair where skills and tools are needed. If the iPhone was dropped in the past or the audio IC was previously repaired that would explain the why, although it would not change the picture.

Im having the same problem, I even changed the busted antenna chip at the local store. Still bricked. Do you think theres a brute force way to activate it? A third party program maybe?
