Some of you may have wanted to test iOS 5 and want to return to iOS 4.3.x. You should know that iOS 5 requires iTunes 10.5 beta to synchronize your device and perform other manipulations. We will therefore explain how to get iTunes 10.3.x back on Windows only.
1. To back up your iTunes data, copy the iTunes folder – located at C: Users YOUR NAME Music – on the desk or in a safe place.
2. Go to Start> Control Panel> Programs and Features and uninstall in order:
- Apple Application Support
- Apple Mobile Device Support
- Apple Software Update
3. Open CCleaner and go to “Register” in the tabs on the left then click on “Check for errors”
4. When the analysis is finished, click on “Repair selected errors”
5. When this dialog box appears, click “No”
6. Another dialog box will appear, click on “Correct all selected errors”
7. Restart the PC
8. Meet at C: Users YOUR NAME Music. Open the iTunes folder then rename “iTunes Library.itl” to “iTunes Library.itl.old”.
9. Open the folder “Previous iTunes Libraries” then find the last file with a date (preferably the most recent) where you did not already have iTunes 10.5 beta (example: “iTunes Library 2011-06-15.itl”> imagine that the June 16 you had iTunes 10.5 beta, this file was created on June 15 in iTunes 10.3.x).
10. Copy this file (in the example, “iTunes Library 2011-06-15.itl”) to the root of the iTunes folder located in C: Users YOUR NAME Music.
11. Rename it to “iTunes Library.itl”
12. Install iTunes 10.3.1 downloaded at the start of the tutorial!
