RecBoot – Put iPhone Into, Out Of Recovery Mode (iTunes Error 1015)
While downgrading your iPhone, you may come across an iTunes error 1015 saying that your device cannot be restored, showing you a ‘Connect to iTunes’ screen. Since iTunes does not let you come out of recovery mode, you need a tool such as RecBoot.
RecBoot, available for both Windows and Mac OSX lets you do only two things – enter and exit recovery mode on your iPhone.The Windows version requires .NET framework 4.0 to be installed on your PC. Also you may have to run the program in compatibility mode if you are using Windows 7 Or Vista. Windows XP users can run the program right away without any issues.

Using the tool is pretty simple. With your iDevice connected to your Computer, hit the Enter Recovery Mode or Exit Recovery Mode to kick your iPhone into or out of recovery with a single click.
RecBoot for OS X does not support 10.4.x machines and PowerPC machines.
