Hi guys, I brought a faulty iphone 5s. It was stuck on “searching”, however once I heated it up with a hair dryer the service came back, so I put the sim in it was locked to and activated it. However the service went again around five minutes after once it cooled down. The phone also restarts every two to three minutes, Any help to fix it would be greatly appreciated!
This is probably a cold solder joint under the baseband, if you know how to reflow it or Reball it try that.
