Itunes cannot read contents of the iphone

Well since I didn't have iFun-Box but iTools, I solved my problem with that (on Windows 7). Maybe try iTools and see if that gives the same unknown developer error. Here is the download link:

Best of luck...

Thanks SlimWithATiltedGrin, this worked for me too! I only deleted the iTunesCDB file, and in iTunes I removed one playlist from syncing to me iPad. Not only did this work, but it reclaimed a lot of free space and got rid of a large portion of my file system called "Other".

Your solution worked perfectly for my iphone 5. The i-funbox was not available in the apple store for download to my phone but I did download it to my Windows PC and found the the 3 files in the iTunes_Control\iTunes library. My "iTunesCDB" "iTunesContol" were both 0KB so I deleted them and then renamed iTunesPrefs to a different name.

I reconnected the iPhone and it sync'd perfectly. You are awesome!

Hi, first leap into a forum so just tell me if this is posted incorrectly.

Teh iFunbox fix is a real lifesaver.....but...(always a but) when i reconnect with iTunes, my phone sync settings are a mit of a mess and i have to reload all music etc and movies. Is there something i can change to avoid this. I have to use ifunbox a few times per week.

THANK YOU SOOOO MUCH!! I don't understand how these errors happen & always get so upset that the solution is always restore. I tried all other solutions, didn't work & was sceptical about downloading a program off the internet that wasn't from a familar site. I did & used i-Funbox & only had to rename the iTunesCDB. Then went to iTunes & it was recognized! Don't t understand how that worked but it did. Thank you so much.🙂

Wow!!! You are my hero! Thank You, Thank You, Thank You, Thank You, Thank You, Thank You! So easy, and it works. I didn't lose anything.

I have tried every fix i could find...nothing worked. And then I came across your post 🙂 My last resort would have been Apple 😕

You saved me from that agony

Please Help!!

I have deleted the CBD file multiple times, restored my ipod nano multiple times and nothing. Itunes loads the music onto the ipod but the ipod says there is not music there. When I delete the CBD file the music turns to other but the ipod is still full. Both my IPOD nano 5th and 7th generations are giving me this message but my IPod touch and IPhone 5s are working fine. I downloaded iFunBox and it does not recognize either nano as being connected but it works with my 5s. Any suggestions anyone????

Will you ever get tired of people telling you are AWESOME?!?! naaahhh right!?! AWESOME!!! I was looking how to fix this problems for so many months! THANK YOU!

Ps. for anyone else with this ****** problem.. Just had rename "itunes CDB" to itunes CDBX and none of my music were deleted. 😀

Just want to add this tidbit to this thread for posterity.

My iphone 4 was failing with this message and some others about not being able to be identified etc. Turns out it's due to a 3rd party USB cable I was using. The cable is long etc and works great for charging but apparently it's not good enough for data syncing. I only found this out by trying another normal cable and seeing it work and then repeating the process to be sure.

Good grief, THANK YOU SLIM!!! I spent forever trying to solve this problem. This same solution using i-funbox worked with my iPhone 5c that i just bought used a couple of weeks ago. This is my first apple device. and so far i'm not too thrilled with it. I thought everybody liked them because they were supposed to be super-duper user friendly? so far that's not what i have experienced....i think i might stick to samsung in the future.

Thanks again!

Oh my goodness, thank you for mentioning this Andrew Diamond! I was having trouble with itunes not recognizing my phone and i was kind of freaking out about it, but as soon as I read your reply...I was so relieved! I just bought a new 10 foot long charging cable and was trying to sync with that hooked into my laptop. As soon as I switched back to one of the regular short cables, the problem was gone!

Thank you!!

Hi, deleting the files with ifunbox works, and I'm able to sync again but I end up losing all my music and playlists on my iphone in the process. Is there anyway to not lose my music and playlists to sync again ?

OK, I have this issue. I tried deleting a track and restarting - that didn't work. I downloaded iFunbox and it doesn't work with the latest version of iTunes so I can't use it. I tried stepping back through the iTunes versions but this didn't work. I don't know what is going on with iFunBox - their forum link has been dead for the last couple of weeks so I don't know if it is even being worked on any more? I tried to follow the link to iTools but that didn't work. I did find the original site for this application but couldn't find a link to an English version. So what are my options to get into my iPhone 6 - delete the file - and re-sync without restoring my phone? Thanks.

This worked for me:

"First try to delete one song from your playlist, and turn off/on your device. This will hopefully overwrite the corrupt database file. Try connecting to itunes again and see if that does it."

Thanks, SlimWithATiltedGrin!

Oh god it works perfectly!!! This problem has depressed me so badly tonight. I don't know how to reply you, but thank you very much!! I wish you a lot of success ahead of you that you've never imagined before!! 🙂
