I had The "Searching" Issue. I gave it ten minutes and nothing. So I reset the network settings via Settings>General>Reset>Reset Network Settings and the problem persisted. However plugging it into my PC seemed to work and it found the network (thank god since this is my work phone). However I do have the problem of the phone resetting itself every minute (quite literally, every minute). I don't know what this could be I've taken another look inside but nothing looks out of the ordinary. Any help would be appreciated.
