    Default Upgrade a jailbroken 3GS from 3.0 to 3.1.2

    I've jailbroken few phones, different configurations, I rarely ask but I am now stuck.

    I have my 3GS jailbroken on 3.0 and I want to upgrade to 3.1.2 as I need some applications which are not currently working on 3.0.

    Following the tutorial from iClarified, I think my best option is redsn0w but when I try to SHIFT+Restore the 3.1.2 (iPhone2,1_3.1.2_7D11_Restore) I got "This device is not eligible for the requested build".

    What should I do? Upgrade it to 3.1 and then 3.1.2? Downgrade the iTunes version? (my current version is 9.0.3.15, on Vista)?

    Googleing the error didn't gave me any solutions. Thanks.

    See Apple stopped signing 3.1.2 for an explanation.

    You are lucky as you have old bootrom and are jailbroken. You can restore with pwnagetool custom 3.1.2 (I don't recommend custom 3.1.3 but it is possible) see iClarified - iPhone - How to Jailbreak Your iPhone 3GS Using PwnageTool [Mac]

    Thank you for the info.

    I should have done this couple weeks ago :/. (upgrading to 3.1.2)

    Is using Pwnage Tool the only option I have at the moment? I really wanted to go to 3.1.2.

    I'm a Windows user.

    Custom IPSW made with pwnagetool can be restored to an already jailbroken iPhone via windows. It is against the rules of this forum for me to link to already made custom IPSW that people may have uploaded to the web. Google for this.

    I have found some custom IPSW's. Now it's all about trust as I am not really decided whether to use one or not but I might give it a go.

    As far as I understand, it's not even possible to return to the factory settings as iTunes checks and installs 3.1.3 anyway, isnt't it? I mean, I was thinking not to restore a custom ipsw but do a normal restore to the original settings but seems iTunes looks for a updated firmware first!

    You are very confused about this.

    1. iTunes checks for updated iPhone OS versions and prompts you to download and install this. You can turn this mostly off.

    2. Resturn to factory settings is either the following:

    Erase all content and settings then restore ipsw and setup phone as new

    Or restore ipsw and setup phone as new if you are less paranoid.

    On old bootrom 3GS that is pwned before the reset factory settings either of these approaches can be used to restore a custom ipsw or an apple IPSW

    3. It is the iPhone that verifies the SHSH during restore. iTunes just resquests the SHSH information from Apple (or cydia/tiny TSS) and then passes it to the iPhone for verification. So the place to patch out the SHSH checks is in the iPhone.

    4. If you don't have a copy of the SHSH that is unique for your iPhone to load OS 3.1.2 then you can never restore to non custom 3.1.2 again . This is because Apple has stopped processing such SHSH requests.
