How to recover iPhone(iTunes) library data from backup applications iPhone is an “almost” perfect, you know. Yet it may happen that due to some applications too demanding in terms of system resources or poorly designed software, the operating system crashes and your iTunes library is corrupted.
In this situation you should create a new iTunes, but, unfortunately, purchased applications on the App Store, will be lost with all their data.
Restore the application is quite easy, because the files are still present in the library, the adress is here:
“~/Music > iTunes > Mobile Applications”
Simply drag and drop these files in the iTunes window, after selecting “Applications” sidebar. At the next sync with iPhone, iTunes will copy the applications to your iPhone by.
Despite this, all settings and application data have not yet been restored: the to have the last save is not helpful. One solution is to use an older backup Time Machine or another backup system.
The procedure of recover iPhone(iTunes) library data is as follows:
1) Disable automatic syncing in iTunes preferences, under “Devices”.
2) Replace ~ / Library / Application Support/MobileSync/Backup/abc123 with an older version taken by Time Machine. 3) Please note that abc123 on your iPhone is a key alphanumeric identification much longer and since it is closely associated with the device, make sure you get the right one if you sync multiple phones or iPods
4) Connect iPhone.
5) Press Control-click (in the iTunes sidebar) at the iPhone and select “Restore from Backup”. At the end of the process iPhone will reboot automatically.
6) Now everything should be in place and the iTunes library completely restored. Do not forget to re-enable automatic sync in iTunes preferences.
