I received this Droid 4 in a lot of phones and am having troubles figuring this one out. Ive looked around the web, found a few similar problems, but i cant get mine to work. The Droid will not detect any sim card installed into it. Ive tried the following: -Removing the battery for a period of time. -Removed and reinserted sim card multiple times -Positioned the sim card in a milliion different ways, rebooted each attempt. -Hard reset -Soft reset -Hold power / volume down -Start in safe mode -fastboot -just reboot Im nearing the end of my options here, not sure what else to do. There has been no water damage to the phone, all indicators are clean Please help!!!
