Restore a 5.1 backup

Here is a little guide to help you with using an old backup on your downgraded iOS Device.
If you’ve already backed up your data using iTunes, skip to step 3.

1. If you did not Update to iOS 5.1.1 (-_-)”
2. Backup your data using iTunes, not iCloud.
3. After that, locate your backup on your computer.
4. For Windows, it’s at “C:/Documents and Settings/[USERNAME]/Application Data/Apple Computer/MobileSync/Backup”. For Mac, it’s “~/Library/Application Support/MobileSync/Backup”
5. Locate your latest backup and search for the info.plist file. Edit it with a text editor and look for this string: Product Version
6. Change 5.1 or 5.1.1 to 5.0.1 and save.
7. You can now restore to this backup on 5.0.1.
