    Corrupt Cisco Catalyst 3550 – Can’t Boot IOS

    Locked

    by forums · about 15 years, 1 month ago

    Hi all,

    I have a Catalyst 3550 48 EMI whose boot image was corrupted. I was
    given no choice but to try to upload a new image via console.

    I followed the advice from the Cat 3550 Config Guide –
    Troubleshooting section, and at the “switch:” prompt, used ‘copy
    xmodem: flash:myimage.bin”

    The image I was trying to upload first, was my primary image –
    c3550-ipservices-mz.122-44.SE.bin
    After 2 hours, it would successfully upload, but when trying to boot it,
    using ‘boot flash:c3550-ipservices-mz.122-44.SE.bin’ I received the
    following:

    switch: boot flash:c3550-ipservices-mz.122-44.SE.bin
    Loading “flash:c3550-ipservices-mz.122-44.SE.bin”…flash:c3550-
    ipservices-mz.122-44.SE.bin: magic nu
    mber mismatch: bad mzip file

    Error loading “flash:c3550-ipservices-mz.122-44.SE.bin”

    Interrupt within 5 seconds to abort boot process.
    Boot process failed…
    switch:

    I tried this twice, and both times didn’t work. I then downloaded an
    earlier IOS version, and tried with that file:”c3550-i5q3l2-mz.121-
    22.EA1.bin”
    Same problem. Here’s my most recent attempt:

    switch: copy xmodem: flash:c3550-i5q3l2-mz.121-22.EA1.bin
    Begin the Xmodem or Xmodem-1K transfer now…

    Any advice? I’ve tried this at 9600, 19200, and 57600 baud, each with
    the same result. I’m using a Dynex USB > Serial adapter, and ZTerm on
    a MacBook Pro.

    Any thoughts or advice?
