    Default BUS ERROR while Downgrading 1.1.1 to 1.0.2: "ZHS: BUS ERROR iEraser"
    Hello,
    I am trying to unlock an out-of-the-box 1.1.1 iphone, i follow the Downgrading guide, and on Step 13 I get this error:

    # ieraser
    Resetting the Baseband...Done
    Opened: /dev/tty.baseband
    iEraser: tool by geohot
    thanks to gray and the dev team for the implementation
    thanks to nightwatch for the awesome toolchain
    and thanks to anonymous, iProof, lazyc0der, and dinopio for the idea for this cool trick
    this tool erases your main fw, starting at 0x20000. you need this for the testpoint to work
    you need a file called secpack matching your current firmware version in this folder
    see http://iphonejtag.blogspot.com for instructions on finding this file
    Waiting for data...

    no i think the problem is the secpack you have to make sure its not secpac.txt change the ending and you will be fine if its hidden go to windows folder options and change the hidden setting
