Can't update iphone. unknown error (-23) help pls!

I cant seem to update my iphone 4. keep getting an error message "unknown error (-23)" anyone can help?

Hi, I've just manually updated mine SUCCESSFULLY! Make sure you SYNC ALL your data first
This was the method I used (courtesy of http://www.nickpan.com/2011/10/15/iphone-ios5-upgrade-unknown-error-23/):
Download the iOS5 manually. See http://osxdaily.com/2011/10/12/ios-5-download-available/
Copy the iOS5 file to (For Windows 7 users) “C:\Users\YourUsername\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates”.
Go back to iTunes and hit “Update”.

HT201263 What does can not restore iphone unknown error occured (3005) mean? is it dead?

I have an Iphone 3. Yesterday it was working fine then Itunes said it had an update. The update was unsucsessful and it said the phone needed to be restored. I went through the restore steps and recieved an error. Any suggestions?

From this support document http://support.apple.com/kb/TS3694
Errors 3000-3999 (3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the update server (gs.apple.com) on ports 80 or 443.
Update to the latest version of iTunes.
Verify the computer's date and time are accurate.
Check that your security or firewall software is not interfering with ports 80 or 443, or with the server gs.apple.com.
Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.
An entry in your hosts file may be redirecting requests to gs.apple.com (see "Unable to contact the iOS software update server gs.apple.com" above).
Internet proxy settings can cause this issue. If you are using a proxy, try without using one.
Test restoring while connected to a known-good network.
Error 3002: If you experience this error while updating an iPod touch (2nd generation) or iPhone 3G, please use the standard update or restore process in iTunes (click Update or Restore).
Error 3014 may indicate that you need to free up more disk space on the computer before trying to restore again.

Please tell us what kind of computer you have, what operating system and what version of iTunes. Not just "the latest version of iTunes", the exact version number.

Try:
iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
Or it could be an Apple problem and you will have to wait.

Iphone ios6 update could not be updated an unknown error has occured 1602

Hello,
So I have an iphone 4s, never had any issue until I tried updating to the new ios6 and shortly while it was applying the ios6 update, it stopped and gave me this error:
could not be updated an unknown error has occured 1602.
To which my Win 7 64 pc would not see it anymore, and itunes would not see it. Went through what apple suggested removed everything and reinstalled itunes, did not work. The only way I could get my iphone working was plugging into another pc running an older version of itunes and restore it. Once done I went back to the original PC worked fine to sync, but when I tried yet again to update to IOS6 it crashed again.
I have spent way too much time on this, spent way too much money on apple products (still need to update another iphone, and ipad, an itouch and an iphone 5), I need this fixed, who can help?
Image shows what happens:

"This error is caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple."
Taken directly from this article http://support.apple.com/kb/TS1275.
Plug your iPhone into iTunes and update it to the latest supported version, which is 4.2.1.

ITunes could not sync ^0 to the iPhone Unknown Error(-19) during 2.1 update

iTunes could not sync ^0 to the iPhone Unknown Error (-19) during 2.1 update
Anybody getting this? On a Win XP iTunes 8/ iPhone 3G
Thanks for any help!

I got this message. After several hours of frustration...
I finally did a successful update by following various recommendations in this thread.
Maybe all or only a combination were necessary:
1) Deleted my backups. This DOES appear to be necessary, I noticed that the update was always failing when the update was going through the backup process. It was only after I deleted my backups that the update finally worked. To do this, in iTunes go to Edit > Preferences. Click on the Devices tab. Click on (select) the iPhone in the window. Click on the "Delete Backup" button.
2) Disable automatic syncing for the iPhone (don't know if this was necessary but it's one of the steps I took)
3) Make sure all your Apps are updated before trying the iPhone update. (Again I don't know if this was necessary but I did it). I updated my apps over wi-fi from the iPhone rather than via iTunes.
Important!!!!! After you run the update there will be no backup of your iPhone. You need to create a new one. To do this, right click (option-click) on your iPhone in the "Devices" list of iTunes. Select "Back Up" from the context menu.
Hope this helps!!!!

if itunes can no longer pickup your ipod, and you cant even do anything to your ipod, your best option is to either call apple care, or just take it to the nearest apple shop. i had a similar problem, mines currently at apple care repairs and they might just end up giving me a replacement.

HT4623 my ipad can't be updated because unknown error (-23) appear in status how can i updated it

my ipad cant be updated because unknown error appear in status of my ipad software unknown error (-23)

I don't see -23 on this support site, but this is what it says about error code 23. It can't hurt to try these suggestions.
Error 20, 21, 23, 26, 28, 29, 34, 36, 37, 40
These errors typically occur when security software interferes with the restore and update process. Follow Troubleshooting security software issues to resolve this issue. In rare cases, these errors may be a hardware issue. If the errors persist on another computer, the device may need service.
Also, check your hosts file to verify that it's not blocking iTunes from communicating with the update server. See iTunes: Advanced iTunes Store troubleshooting—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > Mac OS X > The hosts file may also be blocking the iTunes Store. If you have software used to perform unauthorized modifications to the iOS device, uninstall this software prior to editing the hosts file to prevent that software from automatically modifying the hosts file again on restart.

Make sure you have the latest version of iTunes. You can download it from here -> http://www.apple.com/itunes/download/
If that doesn't work, check out this Apple article -> iOS: Unknown error containing '0xE' when connecting to a Windows PC

I get an error message stating can not update iPhone because an error occurred

Search the forums for the exact error that is occurring and follow the steps found.

Ipod cannot be updated, an unknown error has occurred. (-48)

I'm at the end of my tether right now. I updated iTunes to the newest version, then updated my iPod. Now I'm getting the error message "Ipod cannot be updated, an unknown error has occurred. (-48)". I've searched the site and other forums and I can't find anyone with that same message who can help me. I've tried installing an older version of iTunes but I can't use it because my iPod has been updated to work with the newest one. I've uninstalled and reinstalled iTunes, nothing helped.
So my questions are:
1) Any way I can uninstall the update I did for my iPod? That is, so it is compatible with older versions again.
2) What could be causing this message?
3) Is there an e-mail address for apple, who seem wholly uninterested in what happens with their product once the £235 has been paid for it?
Any help is appreciated.

Interesting, that error code doesn't seem to appear on the iPod support pages. Since it's saying "The iPod cannot be updated" it sounds like it's indicating there's a problem with the iPod... although with "unknown error" it's hard to say for sure. My recommendation would be that you try restoring your iPod, and then giving it another go. If you're uncertain about the restore process, take a look at this article, it should answer your questions.
http://docs.info.apple.com/article.html?artnum=60983
Once you restore it, try updating it again in iTunes. If you have any more problems or questions, feel free to reply, and I'll see what I can do to help.
Best wishes!
