This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode,put it into Recovery Mode.
Restore and wait for the error.
When prompted, click OK.
Close and reopen iTunes while the device remains connected.
The device should now be recognized in Recovery Mode again.
Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.
Error 1600, 1601, 1602
Follow the steps listed above for Error 1604. This error may also be resolved by disabling, deactivating, or uninstalling third-party security, antivirus, and firewall software. See steps in this article for details on troubleshooting security software.

"The iPad could not be restored an unknown error occurred (1604) This i have discovered probably a USB timing problem ?
I have followed all suggestions but still my iPad screen is locked with a iTunes logo and a USB cable beneath it, wish I had never bothered

i have an apple 3g, tried to upgrade it to a 4.2 version, (previously it was 4.1). it wasnt successful, the computer asked us to restore it to the version which was last operational, and while restoring an error message appeared "the iphone could not be restored, an unknown error occured

"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."

Plug your iPhone into iTunes and update it to the latest supported version, which is 4.2.1.

I'm having trouble with my Ipod- I tried to restore it but keep getting a message - the ipod could not be restored. an unknown error occurred(1413)

Mt computer has been freezing up on me lately and I think it messed up my Ipod when it quit right in the middle of downloading and got shut off.

That's because you jailbroke your phone. You can't get help here.

The iPod 'iPod' could not be restored.An unknown error occured(9).

I got my iPTouch 16 GB on Oct.13 and on hooking to XP SP2 PC got it on the iTunes ver 7.4.3.1, was able to download music after charging. iTunes showed that a new software ver 1.1.1 for iPTouch was available(of150MB).Got it downloaded to iTunes but when it started to download to iPTouch, it failed and asked to do resotre. All this happened in just few hours of getting it.
Since then, even after reinstalling the iTunes, my iPTouch is not going beyond showing the icon of a plug and a CD.Every time iTune is able to detect the iPTouch saying that it has detected an iPod in recovery mode, you must restore it. And on doing so that error of 'The iPod 'iPod' could not be restored.An unknown error occured(9).' comes up and it again asks to restore.
Though every time iTunes is able to detect an iPTouch, my XP does not show it in 'my computer' as any hooked device or drive.
May I request Apple and other members on this forum to help me out. It is clearly a software problem.
Many thanks in advance.

Thanks to all members for sharing in. In my case finally, I got a brand new replacement from Apple through their Authorised Service Provider,A-1 Infotech, Mumbai. Since in India, Apple does not have a widespread presence,the service and support I got was amazing.
In my case though I never came to know whether the problem was of software or hardware, but the simultaneous step I had taken was to call the toll free number of Apple in India and got my problem registered. Since the iPod Touch was under warranty, I got it replaced without much hassels. I advise the same path for other users and if possible get the additional Apple Care Protection Plan for additional one more year.
Though I have yet to find out how to avail that Protection Plan in India.
Best wishes,
Jetavya

"the iphone could not be restored an unknown error occurred (2)"

Yesterday I connected my iPhone 4 to my Windows 7 laptop, and went through to install the latest security update for iPhone through iTunes. When it was installing the software update, the phone froaze, and then this happened:"the iphone could not be restored an unknown error occurred (2)"
Now, I have uninstalled and reinstalled both Bonjour and iTunes, to no avail. I have done the iPhone reboot method, and the phone will be identified as "iPhone" but not recognised as mine. iTunes states this phone is in recovery mode and I have tried numerous times to restore it.
Windows doesn't detect the phone while this is happening. It will not restore and the error is still popping up. I have followed as many threads to rectify this but nothing seems to be working.
I can resore it on my iMac but the reset date for the iPhone on this computer is six months old.
Any suggestions?

When you say you uninstalled iTunes and reinstalled it, did you follow the directions in this Apple support document exactly? http://support.apple.com/kb/HT1923
That will make a difference on Windows computers. After that, try and reconnect and restore.

I have tried to hold the "home" and "power" button to reboot
I have tried powering it off
I have tried, to unplug the cable, hold the "home" button and then plug it in.
Can't check the SN or warranty, cause it is stuck in restore mode.
Is the hard drive gone? Should there be something replaced.

This may indicate a hardware issue with your device. Follow Troubleshooting security software issues, and restore your device on a different known-good computer. If the errors persist on another computer, the device may need service.
Usually this is caused by your antivirus or firewall blocking iTunes access to the Internet. It can also occur if the phone is jailbroken or if the computer you are using was ever used to jailbreak an iDevice.

Instructions to get the phone back working temporary.. till there is a real fix.
1. turn off the phone
2. fire up iTunes
3. press and hold the home button, plug in the cable, hold till you get to see the recovery mode
4. iTunes will the allow to choose restore the phone back to 5.0.1 ( no other choice)
5. iTunes will then ask you to choose which previous backup to would like to recover.
(note: please do not reboot your phone unless necessary, i realize at times after reboot, it goes back to sq1)

Are you using a valid Apple charger that came with the iPad?
Attempting to use a computer USB port, an incompatible charger, or attempting to charge via a wall socket that only receives power from a wall switch — can all lead to a low, or depleted battery condition. Has this iPad been wet, or dropped?
Verify all of the above, and correct. If the iPad still cannot hold a charge, consider taking to an Apple Store, or authorized service provider to evaluate it.

Could not be restored. an unknown error occurred (1669)

Dears,
Thank you in advance for your usual support as a community.
Here is my issue,
When I try to restore my iPhone 5 from a backup using iTunes, I get an error message 'could not be restored. an unknown error occurred (1669)’.
I tried Apple articles and everything fine with my mac.
please help me as I have been checking this issue for 5 days with no luck.
I am pretty sure that there is a solution for such an issue and for sure it does not make sense to through this device away with no solution.
Thank you again.

The apple support articles doesn't mention anything about the MAC.
Is your iphone jailbroken? Per apple support page this is a hardware issue.

These errors mean that your device or computer may have a hardware issue that's preventing the update or restore from completing.
Check that your security software and settings aren't preventing your device from communicating with the Apple update server.
Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
Confirm that your security software and settings are allowing communication between your device and update servers.
If you still see the error message when you update or restore, contact Apple support.
Check for outdated or modified software

Your device has a beta version of iOS.
You're trying to install an earlier version of iOS (downgrading).
