An error occurred while restoring this iPhone (-48)

Updating iPhone 4 to iOS 5.

An error occured while restoring this iPhone (-48). Looking for a solution.

I have just upgraded my iPhone 4 with iOS5. The phone tells me that the upgrade was successful but then I try to restore from backup and get the message:

"iTunes was interupted while while restoring the contents of the iPhone "****". Would you like to restore this iPhone again now?")".

(There were no interuptions, unless there was an interuption when the first backup was created.)

iTunes then gives three options: Cancel; Continue Restore; Delete Backup. Meanwhile:-

The iPhone Asks a few setup questions and tells me my iPhone is now set up. All looks good but the all the apps dont open, there is no music, photos etc , just mail and safari and the phone are working. Contacts are there.

After chosing "Continue Restore" in iTunes and after 15sec This message apears:

"The iPhone "******" cannot be synched. The required file cannot be found."

then

"An error occured while restoring this iPhone (-48)."

Any soulutions or work arounds? What is error (-48)? Where can I find the required file? Should I set up iPhone as new IPhone?

I've tried repeating the restore process with all the backups I have but the error loop is the same each time. So I am unable to synch. (I'm using the latest iTunes etc etc and followed Apples kb HT4972 on Updating your device to iOS 5 to the letter.)

If you have any tips let me know. Thanks. Eyes on the road.

Update – Successfully restored my iPhone 4 today! Everything is back!

First the problem:

Updating iPhone 4 to iOS 5.

I have just updated my iPhone 4 with iOS5. The phone tells me that the update was successful but then I try to restore from backup and get the message:

"iTunes was interrupted while restoring the contents of the iPhone "****". Would you like to restore this iPhone again now?")".

(There were no interruptions, unless there was an interruption when the first backup was created.)

iTunes then gives three options: Cancel; Continue Restore; Delete Backup.

Meanwhile:-The iPhone asks a few setup questions and tells me my iPhone is now set up.

On the iPhone, the apps appear but don’t open, there is no music, photos etc, just mail and safari and the phone are working. Contacts are there.

After choosing "Continue Restore" in iTunes and after 15sec. this message appears:

"The iPhone "******" cannot be synched. The required file cannot be found."

then

"An error occurred while restoring this iPhone (-48)."

If I choose “Cancel “instead of “Continue Restore” then I cannot sync. I must restart the restore from backup again… and again.

I've tried repeating the restore process with all the backups I have but the error loop is the same each time. So I am unable to sync. (I'm using the latest iTunes etc etc and followed Apple’s kb HT4972 on Updating your device to iOS 5 to the letter.)

Now the fix.

I repeated the restore process from the earliest backup after the iOS 5 update.

This time I did not do step 3 above.(Meanwhile:-The iPhone asks a few setup questions and tells me my iPhone is now set up.) I left the phone. I did not start the setup on the iPhone and instead chose the Cancel option as at step 2.

Then iTunes usual sync screen appeared. I hit sync or (because I deselected and reselected a sync option) I hit apply. Then iTunes did a sync and all was restored.

Lastly, I went to the iPhone and followed the setup questions and licence agreement and all is well. All apps are working with all my data saved. The music and videos have returned and the contacts are fine.

Summary

Do not do the isO 5 setup on the iPhone until the very end.

Choose “Cancel” after the error message "iTunes was interrupted while restoring the contents of the iPhone "****". Would you like to restore this iPhone again now?")"

Hope it works for you, before you start messing round starting your phone as new or copying hidden backup files.

I have been trying to upgrade my ssoftware from version 4.1 to 5 for the last few days now and I'm not having any luck. When it first begins the download the est. time is 59 minutes. Then when it gets about halfway done, the est. time goes to 3 hourrs and it just stays like that. Now I can't get any apps to work, I lost all my music I had, and I can't get it ervery time I try it does the same thing. I don't know what to do. Can anybody help?

I have the exact same issue. Tried to upgrade iphone 4 from iOS 4 to iOS 5, and cannot get back anything. I tried to cancel and do sync before doing mobile setup, but the sync button is disabled. When I tried to restore again, now the error -50 is coming. 😟.
