    I Have a 4700 where both the flash and boot flash are corrupt
    boot flash has a bad checksum
    flash has wrong magic number

    It only has bootstrap rommon 5.3 and doesnt support ymodem or tftpdnld
    commands!
    there is a command called dnld that says its used for downliad via serial
    but cant get it to work and cant find any info on how to use it
    anybody got any ideas how it works or a way out of this problem

    Thanks in advance

    No can do. 4500's and 4700's require a working bootflash. There is no
    way to download anything from rommon.
