It’s usually caused by a software modification like when a user tries to jailbreak the device improperly, or when there’s an attempt to unofficially modify the operating system. We don’t have your phone’s complete history but boot loop problem does not just occur out of the blue. But since your iPhone has also a more serious boot loop issue, it’s a clear sign that the cause of both must be phone-related. While losing signal reception can happen from time to time, it usually fixes itself as long as the issue is from the network side. I have tried restarting, updating, taking out the SIM card, everything. I finally was able to reset the whole phone and that worked for a day, but now both of the problems are back again. My iPhone started off by losing cell service, it was really spotty off and on in places where it had always had good service before and then after I tried resetting it, it got stuck in an endless loop of reseting and wouldn’t let me do anything.
