When i plug my phone into my computer itunes says it cannot read the contents of my device

Question

When i plug my Iphone into itunes, it tells me it cannot read the contents of my device and i must reset it, so i did. I had to o this a few months back and it gave me the option to keep my pictures etc. This time all my pictures and everything got erased, and to top it all off when i plug it back in it tells me it cannot read my device again and i need to reset again. What is happening?! and can i reset mt phone to a previous time/ate like you can with a computer?

Answer 1

Worked for an iPad 4 (Retina) running iOS 7.0.3. connected to a Mac (Mavericks, iTunes 11.1.2). Although the file system is a bit different than what is shown on the video, the basic same steps can be carried out: download iFunbox (for Mac, obviously), go into "Raw file system", then "iTunes_Control" (you may want to switch to list view to see the complete name), then iTunes. There there was no iTunesDB file but I deleted iTunesCDB (was 0kB, expect that might have been the problem) and iTunesControl (0kB as well). Also deleted the Music folder in the previous directory.
After that I disconnected the iPad from iTunes, quit iTunes, relaunched, and it started sync'ing :-)
Note that now it's telling me that it cannot sync because an additional 10GB is required! Not sure what the problem is because the bar at the bottom of the iTunes window says it still has another 4GB available. I'm expecting there's a problem with how the size of the music is calculated (perhaps because I also sync Genius playlists and mixes), so I disabled music sync'ing for now so it can complete it once. Then I'll hand-pick the music again and hope it works!
