    "Downgrading/Restoring to 3.1.2

    If you find you need to restore or downgrade back to 3.1.2 then you just open up the 'hosts' file under C:\Windows\System32\drivers\etc\ on Windows or /etc/ on Mac (via Go->Go To Folder).

    Open up the hosts file in NotePad (Win) or TextEdit (Mac) and add the line:

    Code:

    74.208.105.171 gs.apple.com

    ..at the end. Save it. Then put your iPhone 3GS or iPod touch 3G into DFU mode and shift+restore to your 3.1.2 firmware. If you get any errors ignore them and repeat the shift+click restore process. The line you added in the hosts file will spoof the activation to Cydia's server for activation. I'm presuming Rock uses the same address to save your ECID SHSH signatures.

    Note that you may need to use an earlier version of iTunes. If you're having problems then download and install iTunes 9 from filehippo.com.

    For more details on ECID signing see Saurik's article here"

    Hasn't worked for me. Seems saurik's method only works for 3G's who backed up previously.

    I tryed saving the host file and it says
    cannot create the C:\Windows\System32\drivers\etc\hosts file.

    make sure the path and file name are correct.

    What should i do? Im running Vista Btw.

    hmm, I'm guessing this won't work if your ipod touch 3g shipped with firmware 3.1.3, will it? (because there is no 3.1.2 to revert back to)
