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.

This means that either your firewall/antivirus is blocking access to Apple's servers, or you have used your computer to jailbreak an iDevice in the past. The link above tells you how to resolve this issue.

I have an apple 3g, tried to update it to 4.2, but it wasnt successful, then they asked me to restore it .. to which im getting an error message of "the iphone could not be restored an unknown error has occured (error 1015), any solutions?

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.

"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.

That error is from jailbreaking your phone. It's now unfixable.

The Iphone could not be restored.An unknown error occurred(1604)

I'm trying to restore my iphone as my iphone suddenly stopped working.I just see silver colour apple symbol when i switch on then it displays usb to itues symbol. thats all..
so when i trying to restore the iphone i get the below message.
The Iphone could not be restored.An unknown error occurred(1604)
i have tried from diffrent computer but i still get the same error.
can someone help...please...thanks

Try the following, which worked for someone else:
Disconnected all other USB items (ext. hard drives)
Disabled Symantec Anti Virus
Reset the iPhone to get the screen with the lead pointing to iTunes (Hold down lock button on top)
Plug iPhone in when this image of Lead/iTunes showing
Start iTunes
iTunes recognised iPhone in Recovery mode, offered to restore
Clicked Restore, it unpacked then tried to run
iPhone flashed then went to black screen, eventually iTunes gave the dreaded 1604 error.
I then unplugged iPhone, but instead of resetting it again (which I've tried about 20 times already), I left it with black screen (although black, screen is definately on as not totally pitch black).
Shut down iTunes
Plugged phone back in (Still with black screen)
Started iTunes, again noticed recovery mode, pressed Recover
The black screen then popped in to life and had a small recovery icon at the bottom in the middle and the restore worked perfectly!!!

These errors typically occur when security software interferes with the restore and update process. FollowTroubleshooting 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.

The iphone could not be restored. an unknown error occurred 1015

Hello everyone,
After upgrading to ios 4, my iPhone 3GS is stuck recovery and I am asked to restore it. However the operation cannot complete since at the end I get an error message that " the iphone could not be restored. an unknown error occurred 1015". What should I do? I am not close to any apple store and I cannot go there? Also, does the warranty allows me to get this fixed?
Thanks in advance

So that means that there is no way this thing can get fixed? How about degrading the ios 4.3 to 4.2? Is there any legal way to do that? Any comment/help is appreciated
P.S: I was thinking about jail breaking it since it is the only way that Google is suggesting. Would that be a better approach since I am tired of living with out a phone?

From the article the question was posted from:
Errors related to third-party security software
Error 2, 4 (or -4), 6, 1000, 9006
Follow the steps to troubleshoot security software. Often, uninstalling third-party security software will resolve these errors.
There may be third-party software that modifies your default packet size in Windows by inserting a TcpWindowSize entry into your registry. An incorrectly set default packet size can cause these errors. Contact the manufacturer of the software that installed the packet size modification for assistance or follow this article by Microsoft: How to reset Internet Protocol (TCP/IP).
Verify that access to ports 80 and 443 are allowed on your network.
Verify that communication to albert.apple.com or phobos.apple.com isn't blocked by a firewall or other Internet security setting.
Discard the .ipsw file, open iTunes and attempt to download the update again. See the steps under "Advanced steps > Rename, move, or delete the iOS software file (.ipsw)" below for file locations.
Restore your device while connected to a different network.
Restore using a different computer.
