Do you mean error 11556? Try the steps outlined in this help document and post back with the results. Hope you get everything working 🙂.

I have the same problem of 1156 error after the ios 5 updat for my iphone and my ipad.

This is not a 11556 error. I cannot sync anything.

Any suggestion? anyone else in my case?

Thanks

yes me as well, i tried to sync photos from my my laptop (which habe been already taken by iphone 4) it worked the first time, however i received this error message: unknown error 1156....any clarification for that? thanks Nancy

I resolved my problem that come from an old xcode version installed. I updated it to the last version that is ios 5 compatible and the sync work well after that. The xcode install do change to the itunes application so my itunes was not compatible with ios 5 cause of that.

Hope it help.

It's been a while since the post above, but I wanted to say thanks for putting some reason behind the issue I was having. I am on 10.6.8 and recently installed xcode for the first time. It definitely was the culprit and the solution was to download iTunes and install it again. Then my phone synced first try.

what is xcode and how do you download it

Mac only

For me, what did the trick was:

1. Connect the device by cable and let the error happen.

2. Switch off Sync over Wi-Fi and Apply the change.

3. Disconnect the device.

4. Quit iTunes and start it up again.

5. Reconnect the device and let it sync all over again.

6. Then you can turn on Wi-Fi syncing again if you want.

This fixed my issue of error 1156. Thanks!

This has also fixed my error! thank you very much!
