Are you trying to downgrade your iPhone?
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.
(from iTunes: Specific update-and-restore error messages and advanced troubleshooting)
If not, try to move or delete the IPSW file and let iTunes download it again.
Rename, move, or delete the iOS software file (.ipsw)
iTunes uses "ipsw" files to restore your device. If those files are unusable, then try deleting them, renaming them, or moving the file to a different directory. This will cause iTunes to download a new copy of the IPSW. When a restore issue is specific to a user, it is likely due to an unusable .ipsw file. If removing the .ipsw file does not resolve a user-specific restore issue, then the issue is caused by other user-specific security software settings or iTunes preferences. Creating a new user will also cause new .ipsw restore files to be downloaded in the new user. You can find the ".ipsw" files in these locations:

Error Code (-1) Can't Restore iPad
Tried updating to the latest OS. It failed and itunes says iPad needs to be restored. Tried restoring and get error code (-1). tried restoring again. It goes through the restore process, completes, then says it needs to be restored (as if that's not what I just did). So I try again and get error code (-1)
I have:
Restarted the pc
Restarted the ipad
Hard reset
Uninstalled and reinstalled the latest itunes
Tried all the different usb ports
Created a new user for the pc
none of which works... still getting the same error or it just finishes and states that it needs to be restored
This is a freshly unboxed iPad 32GB wifi (original ipad) that was given as a replacement for another non functioning ipad
called customer service (the guy was patient and very friendly by the way) but they were unable to find any info on an error code (-1).
Has anyone else received this error code or heard of it? anyone know a cause or a fix?If you can't update or restore your iPad: Press and hold down the home button for five (5) seconds, then (without letting go of the home button) hold on to the sleep button until the apple sign shows up on your screen, and finally (still holding on to the home button) let go of the sleep button, and in a few seconds the image with a USB cable and the iTunes logo should appear.
This process puts your iPad into DUI mode which means that it has been un-bricked and should work properly once you put it into iTunes. Keep in mind though: it won't start up untill you plug it into your computer, let it start up, and sync it to get everything you need.
Best of luck!
Note: If your iPad, iPhone, or iPod Touch ever crash and refuse to work; you can do this process at any time to get it going again. If you're running iOS 5 you don't need to connect it to a computer at all, just configure your device like you did when you installed the software for the first time.

I GOT ERROR 40 AFTER TRYING TO RESTORE MY 5S PHONE THROUGH I TUNES
Hey flo74,
Thanks for the question. I understand that you are receiving an error 40 when restoring your iPhone 5s. The following resource provides information on this error code, along with a potential resolution:
Resolve specific iTunes update and restore errors
http://support.apple.com/kb/TS3694
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.
Common errors: 1, 10-47, 1002, 1011, 1012, 1014, 1000-1020.
Thanks,

My ipod touch encountered some water and wont turn on. Is there anything we can do to get it working? It says error 3104 when trying to restore. thank you
Maybe here:
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.
Test restoring while connected to a known-good network. -

Getting error -34 when trying to restore my ipad
I am getting an error (-34) when trying to restore my backup to my ipad after update to ios 5. Seems to be the same issue as: https://discussions.apple.com/thread/3374362
I have plenty of free space on my 64gb ipad but the settings keep getting defaulted to not downsample my music to 128kb. that would over fill my device. I have been on the phone with apple for over an hour with no end in sight. I have lost many data files including a recorded meeting from this week.
If anyone has any ideas I would love to hear them.
Thanks,
RAConfigure your security software
Check your security software and settings, which can block ports and prevent connection to Apple servers during update and restore.
Common errors: 2, 4, 6, 9, 1000, 1611, 9006, 9807, 9844. Sometimes as a result of this issue, a device might stop responding during the restore process. -
Error occured while trying to restore this iphone (-50)
I was trying to update my iphone 3G software to 4.2.1 (I was running 3. something before then) and I got a message that said "an error occured while trying to restore this iphone (-50)," and my phone has been wiped clean. This happened after updating my itunes to the latest update. In itunes, I now have two options, Set up as a new iphone, or restore from "unkown." Not cool! Any suggestions?
This did not solve the issue for me. I am trying to update to 4.0.1
My hosts file says
# Copyright (c) 1993-2009 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
I also tried it with the second to last line completely removed, so it was
# 127.0.0.1 localhost
# ::1 localhost
Any other thoughts? -
I am getting this error code when trying to open an mpeg4 file "OSStatus error -12909"
Has anyone had this happen to them.
I am new to the support community.
ThanksIs this coming from a link, or from something you are trying to type in the address bar?
Try replacing the "html" at the start with "http",
so if you have html://somesite.edu,
change it to http://somesite.edu. -
