TS3694 what is unknown error 3194

Whilst trying to restore my 3GS the message 'unknown error 3194 occurred'. What does this mean?

It sounds like security software may be interferring. I would try to disable or uninstall any 3rd party security software installed.

Usually occurs on devices that have either been jailbroken or attempts have been made to downgrade the iOS. You can try putting it in DFU mode to restore but you may not be able to fix it. If you phone has been jailbroken we can't support you in these forums as it is against the terms of use.

Also a good idea to do a little research through the 'More like this' panel to the right of your initial post. Each of the threads also contains more leads so it is amazing how much you can learn from them.
Good hunting.

TS3694 I have unknown error (-42110). What does this mean and what can I do about it?

Everytime when I start iTunes I get the message about an unknown error -42110. It has probably to do something with importing music, because I add some new music, but can't find it in my library. When I search I found it, but can't play it or click on it.

What is "unknown error -50"?

I deleted iTunes and a bunch of other iTunes related files and downloaded the latest version and now it works (if you saw my previous post) but now it says "The iTunes Library file cannot be saved. An unknown error occured (-50)." I could just say "Do Not Warn Me Again" but I worry that that will delete my whole library or something if I ignore it long enough. Any guesses as to what I should do? I have a feeling I deleted an important file or something...

redgirl, I had the same error message when trying to sync and backup my iphone. I called apple support and they suggested I turn off my computer and my iphone, restart both, and give it another try. It worked. When I restarted my iMac, the only program I had running was iTunes. It's possible that I had too many programs open before and I just didn't have enough memory or something to do the sync/backup. Who knows. The rep at Apple said he just got off the phone with another user who had the same problem as I did and the "shutdown/restart" option worked for that caller too. Hope this helps.

TS3694 What is iTunes error -42110 ?

Each time my computer launches iTunes (to sync with my iPhone 4S), a message appear mentionning error code -42110, but no solution or explanation provided... So, what is error code -42110 on iTunes (for Windows)?

Unknown error (46) iPhone 3Gs

My friend's iPhone 3Gs is in restore mode and each time I try to restore it I get the message
"The iPhone "iPhone" could not be restored. An unknown error occurred (46)."
I have tried all number of things. Sometimes the code is (47), but 99% of the time the error is (46)
The iPhone will not restore, Software recognises it, but it will simply not restore. I have had this phone previously for a similar issue and I was able to fix it by performing some actions which I can't recall now. I think the code was different that time, but there was some messing about in the registry involved from memory. If anyone can help My friend would appreciate it!
So would I too...
Thanks in advance,
Rudolph

Hello All,
My iphone 3 shut itself down. I tunes would then try to restart the phone, but when it got to the point of saying "contacting the phone" the error message number 46 would come up. So frustrating,
To fix it:
1. I did a unexpected shut down of my computer (holding the power button).
2. I re opened itunes.
3. I connected my home to itunes.
4. I pressed and held the home (bottom button on iphone) and the top button on the iphone, at the same time.
5. After exactly ten seconds I released the top button (your iphone screen may be blank and the phone will disconnect from itunes).
6. I then held the home button (I think thats what it's called, it's the only buttom on the face of the iphone), I held this button until the phone was re-recognized by itunes.
7. I then followed the itunes promts to restore and was elated when it worked. (I also pressed home a couple times out of pure frustration at the point when the iphone screen has a apple on it with a progress bar on the bottom, but I don't think that effected the process.)
I think the real change in the process that worked for me, was putting the phone in DFU mode after the phone was already connected to itunes (DFU process described in steps 4-6).
All the best, LP

Help - Unknown Error 2006 "iPhone could not be restored"

Hi there - has anyone else been plagued with this? I tried to sync my iPhone 3G (less than a year old) and it wouldn't sync. I tried to restore it and it went partially through the process and bailed returning an error. I went to the discussion boards who recommended (not necessarily in this order) rebooting, using a different USB cable, a different computer, reinstalling iTunes, turning off Little Snitch, turning off Firewall, using an on-board USB port. Absolutely NOTHING worked and my phone is bricked. Now, despite everything all I get is "iPhone" could not be restored An unknown error occured (2006).
Can anyone help?
