Probably a hardware failure. Take it to the Apple store for evaluation.

i cannot get my phone out of recovery mode, when I tried to restore on itune it gives me error 1608. please help me
While YOU may not have attempted to jailbreak the phone, SOMEONE ELSE did. Error 1015 occurs by attempting to restore a previously jailbroken phone.
It's very likely you may NEVER get your phone out of recovery mode and your phone may be rendered permanently bricked.
Terms of Use of this forum prohibit the discussion of jailbroken phones. You'll have to scour the internet for a solution to your problem, if indeed one exists. -
Forgot my passcode lock tried to restore it but kept getting an error code 3194
Forgot my passcode lock tried to restore it but kept getting an error code 3194
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.

Hey everyone, I have an old school Iphone 3G, it restarts itself right in the middle of a restoration so I keep getting unknown error message. I don't know why but no matter what usb port I plug it into, the white bar underneat the Apple logo on the iphone will get right close to the end but then like I stated earlier the phone restarts randomly, so it won't let me restore the product because it keeps getting reset by itself.
please help meThanks for helping out, but I already tried these steps.
I even tried this on a iMac with similar results. The only difference was that the errorcode was called 2001 instead of 21.
Today I took the phone to www.iphoneambulancen.dk. A guy (in Aarhus, Denmark) that specializes in iPhone repairs. I figured, that given his occupation he'd seen most errorcdes. Two hours later, he called me back, and told me that he had replaced the battery.
So, it turns out that a broken battery can cause this behaviour.
But thanks again -
My Ipod 4th Gen will not turn on. When I hook it up to the computer I get the ITunes symbol and the usb device on the screen of the Ipod. When I go to restore the Ipod it will not restore. I am getting unknown error code 6.

There may be third-party software that modifies your default packet size in Windows by inserting a TcpWindowSize entry into your registry. Your default packet size being set incorrectly 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 photos.apple.com is not blocked by a firewall, or other Internet security setting.

Errors related to downgrading iOS
The required resource cannot be found: This alert message occurs when your device has a newer version of iOS than what is available in iTunes. When troubleshooting a device that presents this alert message, go to Settings > General > About and check the version of iOS on the device. If it is newer than the latest released iOS version, the device may have a prerelease developer version of iOS installed. Installing an older version of iOS over a newer version is not supported.
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. -

Those error messages are indicative of the Device being Hacked / jailbroken.... If this is the case then you are on your own.

my iphone 4 will not restore when i try to do it i get a error 21 message , what do i try next
Check for hardware issues
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 alert when you update or restore, contact Apple support.

Dear all,
I have created a document on my iPhone, and stored it on iCloud. I have updated the document both on my iPhone and on my iPad. Now, I cannot open the document on my iPhone anymore, even a reset of the phone did not help. Via iPad I also cannot open the file, and when I try to download it to my PC via icloud.com I get an error message.I suspect that the file has become corrupt as I have updated it on the iPhone while I did not have network connectivity.
I have two questions:
1.) Is it possible to recover an earlier version of the file?
2.) What can I do to prevent this from happening again in the future?
3.) Does the iPhone sync changes to iCloud in the background or does the application need to be active?
Thank you,
NiftanWelcome to the Apple Community.
I have seen previous versions mentioned in a pop up message before on iCloud.com, but I'm not really sure at all how it would help, as I couldn't get it to do anything.
The best advice I have at this time is to back up your work on your iOS device by regularly saving it to iTunes, if anything goes wrong you can then either load it into the numbers app again on the device or recover it via iTunes on your computer.
My syncs are immediate, I never get chance to see if it works in the background, sorry.
