Hi, I recently was stuck in a boot loop with error 4013 and saw online that it could be the proximity sensor. I opened up my iPhone XS, unplugged the sensor, and my iPhone could finally boot up. However, now my touch screen isn’t responding, and I’ve tried unplugging and replugging the other sensors. Do I need to replace the screen?
Unfortunately it sounds like the digitizer may have been damaged if none of the other connectors or sensors return function to the device when unplugged/plugged. You could try hard resetting the device to see if that helps but if not, it’s likely the screen that needs to be replaced. Does the phone boot normally now with the proximity sensor plugged in or will that cause it to boot loop again?
