Frequently Asked Questions

What does iTunes Error 1473 mean?
It means there is a hardware failure with the iPhone's cellular modem chip or its connection to the logic board.
Can I fix Error 1473 without going to Apple?
You can try a DFU restore to rule out software issues. If that fails, the hardware is faulty and requires professional soldering repair.
Will a factory reset fix Error 1473?
No, a factory reset alone won't fix it. You must perform a full restore via iTunes or DFU mode. If the error is hardware-related, no software reset will help.
Is Error 1473 covered under warranty?
Yes, if the iPhone is under warranty or AppleCare+, and there is no accidental damage (like water damage), Apple will repair it free of charge.
Can I still use my iPhone with Error 1473?
You can use it with Wi-Fi only, but cellular calls and data will not work. Restoring via iTunes may temporarily fix the error, but it often returns.
