I installed itunes 12.3 on my computer and updated the iphone 4 to ios 7.1. Now when I used your method to downgrade the itunes 12.3 to earlier version itunes 10.7 I get an error message that iPhone cannot be used since it requires itunes 11.1 or later. What should I do to resolve this error?
However, even though this release is still available on apple's website to download iTunes 10.7 for Windows (64-bit) as soon as I try to login my account either on the store or simply to playback some purchased tv shows it won't let me authorize the computer and will pop up an unknown error 11111 saying to try again later.
