Respuesta a "*#06# no imei no service"If you heated a chip and it worked for a week, you need to pull the chip, reball the pads & reinstall it. The problem is a bad solder joint (look also for lifted pads). By "the IMEI ic", are you talking about the baseband CPU?
Respuesta a "Touch ID not working after screen replacement?"The fundamental cause of losing touch ID when you still have the original home button is that the connector isn't cleanly seated. This is the reason for moving the metal plate underneath the connector and it's also the reason people suggest moving the button over with the heat shield intact, so that you never have to disconnect the home button. In addition, Yes, I often have to do a restore to get the touch ID function back.
Respuesta a "TouchID not working after rear camera replacement"Not exactly an answer, but I've not been able to restore touch ID on two phones since the arrival of iOS 10. Original home button on both. Would therefore very much like to hear if you resolve this.
