    You cannot use 3.1 blobs for 3.0.

    Use common sense.

    Edit, see what semaphore said, however if you are using 3.0 blobs, then If you've tried restoring in DFU mode try Recovery mode, if you tried Revovery mode try DFU mode.

    I have tried what you said on normal restore mode and in DFU, also did a mixture of both
    (1st time. DFU first then restore mode, 2nd time. restore mode first then DFU).

    none of those worked, so I'm going to try it on a different machine and see if there is any change.

    I gave an answer to the 1600 error at the top of the last page (post 46).

    For 3.0 I get 00.shsh with +-64kb - I believe this is ok! Right???
    For 3.01 I get 00.shsh with +-1kb - I believe is fake.
    For 3.1 I get 00.shsh with +-64kb - This mean that I also have ECID SHSH for version 3.1 ????

    tks.
    I am now on 3.0.1, assuming that I need to downgrade for any reason to 3.0 can then upgrade to 3.0.1 ???

    Tks

    No, you only have the 3.0 ECID SHSH, therefore you can only downgrade to 3.0, you can not update to 3.0.1 without the 3.0.1 ECID SHSH.

    If you get error 3002, it means you do not have a 3.0 ECID SHSH, and therfore you will not be able to downgrade. Sorry.

    You need a 3.0 ECID SHSH to downgrade to 3.0, 3.0.1 to downgrade to 3.0.1, and 3.1 to downgrade to 3.1.

    Apple is no longer signing 3.0/3.0.1 ECID SHSH files.
    Therfore unless you have them on Saurik's server there is currently no way of downgrading to these versions.

    Default iphone 3gs 3.1 downgrade to 3.0
    I succesfully downgraded my new iphone 3gs that "by mistake" upgraded with itunes to 3.1.
    I did all the steps to downgrade to 3.0 and all worked ok (lucky for me i storage the shsh to the server before) then I jailbroked it with redsn0w 0.8. All ok for then.

    I installed all the essentials upgrades and install the ultrasn0w 9.0 but my phone is not able to read the chip yet.

    What could be wrong????!!!!! I'm one step to make history!!! hahaha

    Ultrasn0w does not work on the 3.1 Baseband.
    When you updated to 3.1, the baseband for the phone was updated.

    The baseband can not currently be downgraded, therefore you can not use ultrasn0w.

    You need to work out what is using port 80 your self. It will generally be something like Apache, IIS etc.

    Assuming you're on Windows, goto start -> run -> type: services.msc and then look for either of those, if they are there switch them off.
    If that does not work, no one else is going to be able to help you as you need to work out what is using it.

    You can not downgrade that unless you backed up your 3.0 ECID SHSH via Cydia.

    And if you actually read the instructions you would know the answer to this, either read, or stop asking questions.
    I am not going to help people that do not bother to follow the instructions.

    You need to read the guide. It is not possible to do this anymore.
    You are out of luck, you can not downgrade your phone.

    Now be patient and wait for the 3.1 jailbreak.
