    I'm currently on 4.2.1 and have the SHSH of 4.2.1 saved. Now I would like to do a fresh restore of 4.2.1 but I cannot do it through iTunes because 4.3 is released. Can I just shift-restore the 4.2.1 firmware in iTunes or do I need to do it another way? Thanks.

    Is it true that you can't do a fresh restore because 4.3 is released? Restore is for factory settings and 4.3 isn't factory.

    I have my 4.2.1 SHSH blobs locally and on Cydia, the 4.2.1 ipsw but I am still getting error 1013.

    Which host am I supposed to put in the hosts file? Or is their an alternative method?

    use Tiny Umbrella to trick Itunes into thinking it's talking to the Apple host.

    I assume you have an ip4. Kick the phone out of recovery using tiny umbrella and you should be okay.

    So I Start TSS Server? Does it matter what gs.apple.com is in my hosts file?

    If you run TU and start TSS the program will take care of the rest for you.
    You dont need to edit your hosts file. Tinyumbrella will do it for you.

    You might need to kick it out of recovery.
    Follow TU's instructions.
    You might have to put your iphone in DFU mode.


    Restore SHOULD error with a 1013 error. Click the "ok's" and close iTunes.
    With your device sitting with the usb pointing to iTunes (recovery mode), enter DFU by pressing and holding HOME + POWER until your screen goes black... then after a count of 2 (1.5-2 seconds) let go of POWER but keep holding HOME. If all goes well you will see nothing but a black screen. If your timing is even a LITTLE bit off, you will see the apple logo and your phone will boot back into recovery mode... Go back and try again
    Put your device into DFU mode and then click 'Fix Recovery' on Tinyumbrella.
    Click 'Yes'
    Your device's screen will turn white and you'll see debug boot information.
    Eventually your device will boot into the activation screen.
    Congrats. You're on 4.2.1 (again)? :)
