回答“No signal after screen repair, Searching... NEW”I have an iPhone 4s and tried replacing the battery yesterday. Kept powering on and off. Still working on that problem but in the mean time I put the old battery back in. It did the "searching..." and stayed that way. Friend suggested trying the network reset. Worked like a charm! I have a 64Gb running iOS 7.1.2. WiFi is back up, it found the network and everything is fine. Now to just solve the battery issue.
