During custom firmware restoration or iPhone OS downgrade, you may encounter various kinds of iTunes errors. Yesterday, I got an email from a reader about an annoying iTunes error during firmware restore:
The iphone “iphone” could not be restored. An unknown error occurred (1015)
Probably you also encounter the same error. To resolve the error, someone has developed a tool called “Error 1015 Fixer”. It’s a very simple tool that comes with a single function, that is to fix the iTunes 1015 error. You can follow the procedures to download and install the tool:
1. First, download “Error 1015 Fixer” from here.
2. The tool depends on LibUSB. So, please also download LibUSB and install it.
Note: For installation procedures of LibUSB, you can refer to its installation guide.
3. When you encounter the iTunes 1015 error, simply launch the tool and click “Fix my Error” button.
4. Then click “Done! Click to exit!”.
That’s it. The iTunes 1015 error should be vanished. Let me know if this tool works for you.
Note: The guide is for reference only. For some reasons, it may not work for you. Use it at your own risk.
