IPhone 4s can not be restored. A unknown error occurred (1)

My phone decided to turn itself off, and now wont restore,just getting the message "iPhone can not be restored. An unknown error occurred(1). I've tried the hold power and home button together but doesn't work.
Any ideas anyone?

Hoping someone has an answer for this as well. Some of the things I've tried are:
- Installing on different machines
- Using different USB cables
- Using different USB ports
- Restoring while the phone is in DFU mode
- Connecting the computer directly to the router
- Restoring on Windows 7 and Windows XP (no access to a Mac)
Each and every time I get the same Unknown Error (1) message.

Try to restore your iOS device two more times while connected with a cable, computer, and network you know are good. Also, confirm 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.

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)

(note: please do not reboot your phone unless necessary, i realize at times after reboot, it goes back to sq1)

"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.

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..

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!!!

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?

TS3694 Hi the iphone iphone could not be restored. an unknown error occurred (56). what mean that?

Hi the iphone iphone could not be restored. an unknown error occurred (56). what mean that?

More than likely a hardware issue. You will need to take your phone into Apple.
You can also use the search function type error 56 and you'll see other threads about the issue. You can read for yourself, if other solution will help.

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.

Hi there vienna.hassan,
You may find the troubleshooting steps in the article below helpful.
iTunes: Specific update-and-restore error messages and advanced troubleshooting
http://support.apple.com/kb/ts3694
Error 9
This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if you manually disconnect the device during the restore process. You can resolve this issue by using USB troubleshooting, using a different Dock Connector or Lightning Connector to USB cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.
