    Recently I was attempting to restore my iphone from the newest 4.3.1 jailbreak using itunes. It got all the way to the end of the restore process but a window would pop up saying i had a 1303 error. The only message i get on my iphone screen is the one that shows a picture telling me to connect my iphone to itunes. I have tried putting it in recover/dfu mode but nothing seems to work.
    Any help would be greatly appreciated

    You have to use TinyUmbrella to fix recovery. Once you open TinyUmbrella all will come clear.

    Good luck

    Your PC's host file has been modified or you have Tiny umbrella installed on your PC.

    Here is the steps to modify your host file;

    Mac OS X:

    Step 1. On your Mac, go to your “Applications” folder.

    Step 2. Now navigate to the “Utilities” folder.

    Step 3. Launch "Terminal".

    Step 4. Type "sudo nano /etc/hosts" (without quotes) and hit return.

    Step 5. Enter your password

    Step 6. Use the down arrow key to find the “gs.apple.com” entries. Once the cursor is in front, make sure you comment out the line(s) by entering “#” in front of the text.

    Step 7. Save the file by pressing CONTROL+O.

    Step 8. Exit the nano editor by pressing CONTROL+X.

    Step 9. Restore your iDevice.


    Step 1. Start –> Programs –> Accessories
    Step 2. Run Notepad or WordPad
    Step 3. Click “Open..” from File menu.
    Step 4. Browse to Windows/System32/drivers/etc
    Step 5. In "files of type:" select all documents
    Step 6. Open "hosts"
    Step 7. Delete all line that has "gs.apple.com" or something like that
    Step 8. Hit Save
    Step 9. Restore your device

    Or you can open TU, click advance tab and uncheck the box it say set host to Cydia.
