iTunes could not restore the iphone because an error occurred -1
Hello,
After upgrade an iPhone 4 to os 5.1, I can't restore the backup : while restore I get the error iTunes could not restore the iphone because an error occurred -1. I tried to reset the iPhone, but it restores alwayds whit os 5 and not 4. Each time I connect the iPhone, il runs un recovery mode, but recovery fails with error -1.
Any help ?
Thx
iPhone 4, iOS 5.1
