HT201263 unknown error (1015) is showing on my iphone 3 when im trying to restore settings

unknown error (1015) is showing on my iphone 3 when im trying to restore it

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.

HT201263 my iphone 4 went into recovery mode & will not restore. Unknown error 21 comes up on iTunes. Please can someone offer any ideas for a solution?

I have an iphone 4 nearly 2 yrs old. It has worked perfectly for that time. On Friday last (whilst away on holiday) I took the phone out of my pocket & it was lifeless. I tried switching it on, no joy, I tried the power/home button reset no joy. I plugged it into a mains charger & it came on but had a banner across the screen saying "verification required". I removed the charger & decided I would try again when I got home so I could connect to my PC & iTunes.
At home I went through the whole above process again but when I plugged it into the mains again it just had the Apple logo going on/off repeatedly. I plugged the phone into my PC & the apple logo appeared followed by the "connect to iTunes". In iTunes I get the banner "iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes". So I click on "OK" the "Restore" then a banner asking if I'm sure I want to restopre the iPhone appears, press "Restore & Update". iTunes starts to remove the software, veryfies it with Apple & then another flag "The iPhone could not be restored. An unknown error occurred (21) which appears to be a security issue.
I thought the above problem was something to do with O2 because I picked up my new iPhone 4S last Tuesday but was unable to set it up until I got back from my holiday, O2 say it isn't anything they've done.
My question is has it happened to anyone & can anybody offer a solution, is it a hardware or software issue?

HT201263 My ipod touch does not restore properly and comes up with an unknown error (9). What do I do?

My ipod touch does not restore properly and comes up with an unknown error (9). What do I do? I have tried restoring it a few times and it keeps coming up with this error. Yet on Itune on my computer, it tells me that the ipod software is up to date. ipod screen is just showing the itune logo and a usb connector.

Error 9
This error occurs when the device unexpectedly loses its USB connection with iTunes. This can occur if the device is manually disconnected during the restore process. This issue can be resolved by performing USB troubleshooting, using a different USB dock-connector cable, trying another USB port, restoring on another computer, or by eliminating conflicts from third-party security software.

Hi msclaude,
Welcome to the Support Communities! I'm not sure from your post what steps you have tried, but it sounds like you may need to use recovery mode to address the issue with your unresponsive iPod touch.

http://support.apple.com/en-us/HT201263
If you can't update or restore your iPhone, iPad, or iPod touch
You can put your iOS device into recovery mode, then restore it using iTunes.
Use recovery mode
You might need to use recovery mode to restore your device in these cases:
iTunes doesn't recognize your device or says it's in recovery mode.
You see the Apple logo onscreen for several minutes with no progress bar.
You see the Connect to iTunes screen.
Learn what to do if you see the progress bar onscreen for several minutes.
To put your device into recovery mode, follow these steps:
Turn off your device and leave it off.
Plug in your device's USB cable to a computer with iTunes.
Hold down the Home button on your device as you connect the USB cable. Keep holding down the Home button until you see the Connect to iTunes screen.
When you see this screen, release the Home button. If you don't see this screen, try steps 1 through 3 again.
When your device is connected, iTunes will open. You'll see a message saying that iTunes has detected an iPhone, iPad, or iPod touch in recovery mode.
Use iTunes to restore your device. Restoring in recovery mode will erase your device. If you previously synced with iTunes or iCloud, you might be able to restore from your backup.Get more help
Learn what to do if you don't see your device in iTunes for OS X, or in iTunes for Windows.
If you put your device into recovery mode by mistake, restart it. Or you can wait 15 minutes and your device will exit recovery mode by itself.
I hope this information helps ....

Unknown Error during Recovery - iPad no longer Recognized by iTunes

I have a 3rd Generation iPad which I was attempting to perform a factory reset. I received an "Unknown Error" during the process and from that point on I have been unable to get iTunes to recognize my iPad in recovery mode (or otherwise).
I have tried every thread on the subject, but I found one interesting thing. If I connect the iPad with the same cable, etc. to another computer it immediately recognizes it in recovery mode and offers to restore the iPad.
It seems like my computer is not recognizing the iPad because it was in the process of restoring the device when the error occurred. Does anyone know if there is a way to reset or fix this issue. I would prefer not to update iTunes and download both the new iTunes and iPad software again and use another computer if it is not necessary.
Any help would be appreciated.
Thanks

Hey KSHItunes,
That was a good test to try your iPad on another computer. It does seem to isolate the issue to something with your computer setup.
Although you would prefer not to update iTunes, there may be steps in this article which can help.
