    Default Restoring custom 3.1 IPSW on a factory 3.1 iphone - works?

    Hi,

    I just purchased a 3GS today.
    I tried searching the forums but the information I found is unclear.
    My iphone is locked to at&t and came with 3.1 out of the box.
    if I restore a custom 3.1 IPSW using itunes, will it jailbreak?
    I am not interested in an unlock so I know redsonw wont work, by question is about using a restore of a custom IPSW.

    Thanks!

    No

    Unless you have your SHSH blobs on Cydia server ( & you want have if its new 3.1 OTB device) you cant downgrade to 3.0/3.0.1 fw.

    With the pwnagetool 3.1.3 released today you need to be able to downgrade to 3.0/3.0.1 & jailbreak 1st

    Then you'd apply the latest 3GS pwnagetool custom firmware & it would work correctly.

    In another word, to be able to use custom firmware 3.1 for iphone 3GS; your iphone 3GS HAS TO BE in PWNED state from a previous firmware version. Meaning your iphone 3GS has be already in a Jailbroken state.

    Custom firmware will not work in a "new in box" iphone 3GS with firmware 3.1

    And for those who has jailbroken 3GS with firmware 3.0/3.0.1 and the phone is not booting / hanging at Apple logo and you cannot perform a restore. If you have been waiting patiently and resist the urge to restore with Apple orgininal 3.1 fw, you now can create custom firmware 3.1 and use it because iboot on the device is still pwned.

    For any reasons, if you encounter error when restoring custom firmware 3.1 to your pwned device. Do not panic if you are stuck in recovery mode. You can use irecovery to kick it out and restart the restore over in "Recovery mode" not DFU mode

    Thank guys.
    I thought that if I followed this guide : http://www.hackint0sh.org/f203/87785.htm and get my 00.shsh generated for 3.1 and get tinytss running I would be able to since I am trying to restore from 3.1 to a custom 3.1.

    I guess I was wrong since this took is only if in the future I would like to downgrade to 3.1 from a higher version.

    So can I upgrade to Apple official 3.1 and then downgrade and jailbreak if I have my SHSH blobs on Saurik's server?

    If you're Officially unlocked like your signature says you are & you have your blobs with Cydia server, Yes you can

    But make sure you use a non activating 3.1 custom IPSW so that itunes activates the phone otherwise your have no signal.

    In order to restore iPhone to factory settings, you can try the following steps, hope it can help you indeed.
    1. Connect the phone to your computer with a USB cable. Use a port on the computer, not a hub.
    2. Click on the name of the phone in iTunes.
    3. Click the "Restore iPhone" button
    4. When the restore finishes and you are given a choice to restore from backup or restore as New, choose Restore as New.
    After restoring you can manually add back your apps and music. All other content will be lost, unless you synced your contacts, calendar, notes and photos with apps on your computer or with iCloud.
