    Hi.
    Mine iPhone 3Gs is in iOS 4.2.1 stock and I would like to jailbreak it.

    I remember I saved my SHSH on Cydia when mine 3GS jailbreak during iOS 3.1.3.

    I downloaded tinyumbrella but there is not checking button available. How do I able to check mine SHSH still with Cydia?

    Run TU and make sure your iPhone is plugged in.
    Then click save shsh.
    It will retrieve and display all available blobs for your phone.

    Hi Applejuiced,
    Yes, I did that.

    I can see mine iPhone 3Gs listed from iOS 3.1.3 to 4.2.1 in the TU.
    After that I tested mine new iPhone 4 which never been jailbreak before, it also show iOS 4.0.1 and 4.2.1. Is TU connected to Cydia to retrieve these information or it just retrieve from the phone itself?

    No theyre all pulled from Cydia and apples servers.
    Shsh are not located on the phone.
    Whatever is displayed on TU is all you have available to restore to.

    No, if you never did it before the only shsh you will get now is 4.2.1 and higher.
    So you will not be able to downgrade it.

    plug your phone into your computer and fire up tiny umbrella.
    hit the "save SHSH" button and see what blobs it saves for you.
    if all you see if 4.2.1, then you're stuck on that firmware.
    if you see anything lower, then you are able to downgrade.
    simple.

    a much easier way is the following:

    download TU
    plug iPhone into your computer and fire up TU
    once connected, click "Save SHSH" and TU will save ALL blobs cydia has saved in the past
    click on "Enter Recovery"
    click on "Start TSS Server"
    load itunes
    download previous firmware from http://www.felixbruns.de/iPod/firmware/
    shift + restore

    you can only downgrade to a firmware listed in the "saved SHSH" section of tiny umbrella.

    i've never bothered with bootroms as i'm from australia and we can buy factory unlocked phones.
    read up on bootroms yourself and downgrade if applicable.

    Hi barneyevo,
    That mean i should download the firmware base on the SHSH listed?

    If I able to make download to 4.1 and with new bootrom, can I restore back the stock firmware in future incase I change mind?

    Thanks barneyevo.
    Thanks Applejuiced.

    One more thing, this is safe process, if anything goes wrong, i always can restore via iTunes with stock firmware?

    Correct.
    You can always go back to factory spec firmware just by restoring.
    Good luck bro.

    Hi,
    I managed to download mine iPhone 3GS iOS4.2.1 to iOS 4.1 with your help.

    On my main iPhone 4 which I TU and it found only:
    iphone4 4.2.1 (8C148)
    iPhone4 4.3b2 (8F5153d)

    This mean I cannot downgrade to iOS4.1?

    Downgrade not working

    I accidentally upgraded my iPhone 3GS to 4.2.1 without holding the option key and thus my baseband was upgraded to 05.15.04. I have SHSH 4.1 (8B117) according to Tiny Umbrella, but when I try to follow the aforementioned instructions nothing happens. iTunes displays the following error message "The iPhone could not be restored. An unknown error occurred (1015)" I click 'ok' and then 'Exit Recovery' on Tiny Umbrella, but to no avail. It's still locked and there is no jailbreak software (greenpois0n, redsn0w, limera1n) that will unlocked it. They all fail midway through.

    Is there anything I can do?

    You can't downgrade bb. Your only option is to use the iPad bb. Hope you don't need your GPS or need to take it into apple.
    Ultrasnow is the only software that unlocks.
