Thread: Tutorial : Which bootROM ( boot loader ) do i have 3GS

    Default Tutorial : Which bootROM ( boot loader ) do i have 3GS
    Lot of people asking this question, though i would help out.

    Method 1

    Put into DFU mode, robotic instructions here, lol.
    On your computer... Start > Control Panel > System > Hardware > Device Manager
    Find "Universal Serial Bus (USB) Controller", subitem Apple Mobile Device USB Driver.
    Right click, choose Properties, go to Details, select
    Device Instance Path from the dropdown box. The end of this info string will tell you the bootrom version, e.g. iBoot-359.3.2

    iBoot-359.3.2 is the NEW BOOTROM
    iBoot-359.3 is the OLD BOOTROM

    Method 2

    Install usbview link here
    Put the iPhone 3GS in DFU Mode
    Run the Application usbview
    Check if you find:

    iBoot-359.3.2 - then its the new bootrom
    iBoot-359.3 - is the old one

    Now, how do you exit DFU without restoring the FW?

    Hi All,

    I've just tired both methods mentioned above and I cannot find the iBoot listed at all.

    This is what I get when I use USBVIEW with iPhone in DFU:

    Device Descriptor:
    bcdUSB: 0x0200
    bDeviceClass: 0x00
    bDeviceSubClass: 0x00
    bDeviceProtocol: 0x00
    bMaxPacketSize0: 0x40 (64)
    idVendor: 0x05AC (Apple Computer)
    idProduct: 0x1227
    bcdDevice: 0x0000
    iManufacturer: 0x01
    iProduct: 0x02
    iSerialNumber: 0x03
    bNumConfigurations: 0x01

    ConnectionStatus: DeviceConnected
    Current Config Value: 0x01
    Device Bus Speed: High
    Device Address: 0x02
    Open Pipes: 0


    Any ideas.

    Thanks

    Are You Sure That is on DFU Mode or Recovery Mode?
    For DFU Mode There is nothing on the screen (totally blank) for recovery mode theres a picture telling you to connect to itunes to restore.

    Yep, the iPhone was in DFU mode.

    I've sorted it out now anyways,

    In USBVIEW, I had to ensure that 'Config Descriptors' and 'Location IDs' were ticked under the 'Options' menu. Once I had done that and refreshed my view I could then see the iBoot version, which is the new one :-(.

    I've jailbroken with Spirit, but I can't update to IOS4 until they find an exploit for the bootrom.

    Thanks for the reply ;-)

    yes it is...in the longest string in the end it is....[iBoot=359.3]....you have old bootrom

    Hey, I tried to see my bootrom using f0recast (without putting the 3GS in DFU), and this is what it says:

    - Baseband: 04.26.08
    - Bootloader 6.4
    - Model MC135

    I purchased the 3GS back in August 2009, meaning I should have the old bootrom, but 6.4 seems too new. What do you guys think? I think f0recast is wrong....

  11. #11
    On mine, f0recast says the samething about the bootloader.... best way to tell is to follow the guide above by using USBVIEW or Device Manager in Windows.

    This is all I have..... and I show the same with the usbview....

    So, what's wrong? the usb and itunes icon is on the screen, aka recovery mode....

    Any help would be appreciated....

    TheeApostle - you need to put the phone into DFU mode, and not Recovery mode.

    Also, once you do this and get into the Devices screen in Control Panel, remember to select "Device Instance Path" as shown in the screenshot.

    I think that's an iPhone 3G and not 3GS.

    Old and new boot room testing is only needed for 3GS models (in any case, remember that if you are updating to iOS4, do not do so from iTunes if you want to JB/Unlock).

    well.... not sure now.... I will definitely ck it out and get back to you. thanks so much for your comments.
