I have a POP and an IMAP (mobile.me) mail account on my Mac which I also have on my iPhone. Email works fine on both devices but on every iPhone Sync attempt in iTunes I get the same error message as per the following image.

An unkown error occurred -1

Hi Everyone,


Im in desperate need of help if possible.  My iphone suddenly stopped working today (for no reason) and told me that it needed to be plugged into itunes for a restore.  I tried to reset the phone thinking this was an odd error but upone reboot, the phone gave me the itunes symbol and would do nothing else.  Upon connecting to itunes, the phone fails restoring at updating firmware and gives me an error code of (-1).  Im at a complete loss..and its christmas eve.  Im in a panick on what to do and apple stores are closed until monday.  If anyone can help me, id really appreciate it.

Unknown Error Occurred

I am new to iTunes and iPhone. I had purchased some items from iTunes and I was wanting to transfer them to the iPhone, but I mustve done something wrong.
The iPhone shows a small rotating dial at the bottom of the screen like its trying to download a page or something, and I think its frozen. It wont cut off or do anything. I tried unplugging the USB cable and plugging it back in and then I got an message that says iTunes could not connect to the iPhone because an unknown error occurred (0xE800028).
I tried powering down my computer, but nothing has changed. Anyone have any idea what I did wrong or is my connection speed so slow that its taking forever for my iPhone to complete a task?

An error occurred while backing up this iPhone -54

iPhone 3GS 16GB on 4.3 Software... trying to update to iOS 5


Can anyone tell me what the this is?


Frustrating - tried it last night when I got home from work, several times, figured Id try it tonight since maybe it has to do with traffic somehow, but still it persists. Tried different USB ports, different cables - Ive never had issues upgrading before.

An error occurred while backing up this Iphone -50

Hello all,
Ive downloaded IOS4 and am trying to upgrade by 3G, but when I hit the upgrade button, Im told repeatedly that theres an error backing up the Iphone (-50). Ive reset the Iphone, turned off my firewall, rebooted, but I get the same message.
The thing is, I remember several months ago that my syncing was taking an hour every time because of the back ups. (I keep a large amount of data in a third party app.) I came here and learned how to prevent my 3G from backing up every sync, and my syncs have gone really fast since then. The problem is that Ive forgotten what I did or how to change the settings. If I right-click Iphone under Devices in Itunes, I dont get any option to create a backup, nor can I find any backup command anywhere in Itunes (latest version).
I cant even figure out where to go (assuming there is a place to go) to check when my Iphone was last backed up. Itunes is giving me the option to go ahead and update without a backup, but I dont want to do that until I at least know when was the last time my Iphone was backed up.
Can anyone tell me (a) where to go to check my backup history, and (b) how to get my phone to back up, assuming that its not doing so? Thanks!

I keep getting Unknown error occurred 21 while trying to restore

My iphone 4 will not turn on after being dropped. It wants to restore, I can connect to itunes and it detects my phone but at the end of the process after a minute of itunes saying preparing iphone for restore the phone goes back to the apple screen, disconnects from itunes and the error message pops up. Phone goes back to the itunes plug in screen. I have tried everything suggested on here, even had the battery removed and replaced because I saw on here that helped some people. I could pay for a new battery but if that doesnt work I have wasted my money. Any ideas?

I keep getting 'Unknown Error occurred 21' while trying to restore

It started with the apple logo just flashing on and off. So I went to reset my daughters iPhone by pressing the on/off button and the menu button simultaneously until the iTunes logo and the USB cable was shown on the screen. At that point, iTunes wrote;


iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.


I clicked OK and then Restore. ITunes then went on by extracting software... for a minute or two and then Preparing iPhone for restore...  The apple logo was then shown on the iPhone and a message box i iTunes;


The iPhone iPhone could not be restored. An unknown error occurred (21)

The message box leads to More Information that says that the error 21 typically occur when security software interferes with the restore and update process




Thats it. I have tried everything. (I think);


Checking for iTunes updates

Checking for OS (Win7) updates

Restarting the computer

Changed the USB cable

Changed the computer

Ensuring that I have administrator privileges and that iTunes has it as well.

Disabling the antivirus

Disabling the firewall


If you have any advice, please let me know.

an error occurred while backing up this iphone

trying to update iPhone 3G 16GB to IOS4 (from 3.1.2)
Have succeeded with one, but the second is having trouble.
It comes up with the following message
an error occurred while backing up this iphone (-402636798). Would you like to continue without backup?
Continuing without backup will result in the loss of all contents on this phone.
Has anyone else come across this?
Any solutions?
Can I just do it anyway and then restore from a previous backup?

Any one else seen this and have a fix?
I found a quick work-around.
Go to iTunes 8 Menu Bar
Store>Turn off Genius (irony anyone?)
Turning Genius back on brings the problem back.
Looks like iPod touch users who got this on Tuesday have been having the same problem.

Remote app - An unknown error has occurred

So I have Remote installed on my iPhone. I tried to use it today for the first time. I saw my shared library, got the passcode on the phone and entered it in iTunes on my MacBook Pro. When I try to use the app on the phone it connects, I see my iTunes library and I can view songs, playlists, etc. But as soon as I select a song, a window pops up on my iPhone that says, An unknown error occurred. Please check your library and try again. Okay, what in the world is that supposed to mean?

Restore Failure to 2.0.1 - unknown error occurred 6

After downloading the new 2.0.1 update, with my iPhone 3G connected iTunes tried installing the new software update. It somehow failed, after deleting the old 2.0.0 software, and said, The iPhone iPhone could not be restored. An unknown error occurred (6). After turning my iPhone off and on, attempting many times to run the restore, it kept giving me the same error?
What do I do? Any related input would be much appreciated.

An error occurred while restoring this iPhone -402620415

When will I learn not to do upgrades while Im traveling? Sigh...
Im on the road, and without thinking, clicked OK to the upgrade this afternoon. After a while of downloading, backing up, and verifying, eventually things hit a snag with An error occurred while restoring this iPhone (-402653091). Restarted the phone, got the message iTunes was interrupted while restoring, asked if I wanted to continue. That seemed promising, so I said yes. However, now it continues to just say An error occurred while restoring this iPhone (-402620415).
My full back-up is still on my hard drive in ~/Library/iTunes/Mobile Backups, and I can do a restore to some default OS 4 install (in ~/Library/iTunes/iPhone Software Updates, but after doing the restore, I always still get the same error message when its actually trying to restore the data.
Sometimes after this, the computer says it doesnt recognize the phone (once, it had to go through ATT activation? I got a message to wait a while during activation, and eventually a message that my iPhone was ready to use- but iTunes was asking whether I wanted to set it up as a new phone, or restore from a backup)
So, it looks like I can get it to a point where it can boot and probably send/receive calls, but my data is hosed, and I cant manage to make it restore from the backup that it made. Ideally Id find a way to get around the error and restore, since Im on the road and wont be back on the home computer for a bit. At this point, anything that lets it recognize my phone as an instance of my old phone would be good, though.

The iphone cannot be synced An unknown error occurred 13019

After reading discussions on this error, I found a fix and had to share.
I have the iPhone 3G (16G). I upgraded iTunes and iPhone 3.0 When I tried to sync, it gave me the error The iphone cannot be synced. An unknown error occurred 13019
I unchecked the Music> Sync Music option. It gave me the Are you sure you do not want to sync music? I chose the Dont Sync Music button and the sync was successful.
I then checked Music> Sync Music option and was able to successfully load all of my music back... granted, it took time to reload.
Im no expert, but since it worked for me... I figured it was worth posting.

Can't add page to Home screen because an error occurred

I finally had a moment to upgrade to 1.1.3, and everything works great, except for web clips, which is the one thing I really wanted to do! I go to a web page, click the plus sign, and choose Add to Home Screen. It shows the icon for the page and lets me change the name. Then when I click add, I get the following error message:
Could not add this page to the Home screen because an error occurred.
This happens so far on any site I try it on, whether or not the site has a pre-made iPhone icon. I have already tried restoring my phone with no luck. Anyone know whats going on?

ITunes could not back up the IPhone phone name because an error occurred

I just tried to do a sync on my iPhone 4 to my IMac where my ITunes are actually stored. For some reason I got the error that is the subject of this post. My IMac is up-to-date, and I normally sync every Sunday to keep my IPhone as up-to-date as possible.
The only things that I have done differently this week: I installed Apple TV, I cant imagine that this makes any difference, other than I have another Home Sharing device in the house. Other than that, I updated my apps separately on both the IPhone and the IMac prior to syncing. The numbers waiting to be downloaded on ITunes was irritating me, but I didnt feel like syncing at the time.
Is anyone else getting this error, and if so, have you been able to resolve it, and how?
