I am trying to restore software on my iPad which is connected to my PC with iTunes when i'm in recovery mode a warning comes up
"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
to update it now. Any help would be appreciated. rg

When I restart my iPad the connect to iTunes comes up and stays on until it shuts down again, I have read a report from Apple support suggesting I reinstall iTunes so I might try that again and also your suggestion which i shall also try, but thanks again - rg1547

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..
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?

This is usually a bad Hardware Error, most often the result of Water Exposure. Sometimes it is baseband chip damage which is fatal to iPhone. Some have fixed this Error with Battery Replacement or Dock Connector Replacement. If you have Warranty or AppleCare Coverage take iPhone to Apple for resolution.

Hey cellocan!
I have two articles for you that can help you address this issue:
Resolve iOS update and restore errors in iTunes
http://support.apple.com/kb/ts1275
Resolve specific iTunes update and restore errors
http://support.apple.com/kb/TS3694
Check for hardware issues
Related errors: 1, 3, 10-47, 1002, 1011, 1012, 1014, 1000-1020, 1669.
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.
Error 1015 might happen after making unauthorized modifications to iOS, also called "jailbreaking."
Take care, and thanks for visiting the Apple Support Communities.

"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.

the iphone could not be restored. an unknown error occurred (1015).

Error 1015: This error is typically 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. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state.
