Detailed Solutions for Apple iPhone, iPad, iPod touch iTunes errors (2)

Postby Jacob Black » 03 Aug 2016 14:50

Previously we released a post “iPhone iPad iPod iTunes Errors with Solutions”, and if you can't solve iDevice's problem after viewing that post, please view this post with more detailed solutions for Apple iPhone, iPad, iPod Touch with iTunes errors.


Error 1 or -1
This may indicate a hardware issue with your device. Follow Trouble shooting 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.
This device is not eligible for the requested build (Also sometimes displayed as an "error 3194")

1.Update to the latest version of iTunes.
2.Third-party security software or router security settings can also cause this issue. To resolve this, follow Troubleshooting security software issues.
3.Downgrading to a previous version of iOS is not supported. If you have installed software to perform unauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. Uninstall the unauthorized modification software from the computer.
4.Edit out the "gs.apple.com" redirect from your hosts file, and then restart the computer for the host file changes to take affect. For steps to edit the Hosts file and allow iTunes to communicate with the update server, see iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store. If you do not uninstall the unauthorized modification software prior to editing the hosts file, that software may automatically modify the hosts file again on restart.
5.Avoid using an older or modified .ipsw file. Try moving the current .ipsw file (see Advanced Steps > Rename, move, or delete the iOS software file (.ipsw) below for file locations), or try restoring in a new user to ensure that iTunes downloads a new .ipsw.

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.

Error 20, 21, 23, 26, 28, 29, 34, 37
These errors typically occur when security software interferes with the restore and update process. Follow Troubleshooting 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.

I have encountered itunes error 9 before, and I exhaust most pracitical solutions I can find on the Internet.
I was unable to restore my iPhone because of the error 9, so I thought everything will resume normal if I can just restore my iPhone somehow.
I searched for how to restore iPhone without iTunes, then I found tuneskit ios system recovery, which successfully restore my iPhone and it works properly again.
So I think anyone who has the similar issue should try this program, it's pretty effective and charges only a reasonable sum of money.
