How to repair Corrupted IOS image in Rommon mode without remove all files in flash

[hansfry.ko]

Hi ,

Every time I do tftpdnld on ROMMON mode. why it always delete all my flash files? is there anyway for me to just copy bin file to the flash without having flash directory deleted, as there is some files that I want to keep there.

Hi All,

     So actually there were two discussions that I post. it was merged to this one post.

  Ok the first problem. was solved 

  I have Cisco that goes to the Rommon because of Image bin file issue, whenever I do tftpdnld (copying bin files from my computer to flash: ),the  flash directory was cleaned up first. I don't want  that happens. so After searching again from internet. I found that I can boot from usb, with command:   boot  usbflash0:c881imagefilename.bin

after I can boot normally, then I could just copy bin file from Usb to flash as usual.

so my first discussion was cleared.

The switch could wind up in ROMmon mode due to these reasons:

1. A switch reload or crash after the image was corrupted or deleted. See the Recover from a Corrupt or Missing Image section of this document for more information.
2. See the Recover from a Continuous Reboot section of this document to determine if a valid system image is present in the bootflash:. If there is no file present, see the Recover from a Corrupt or Missing Image section of this document.
3. The boot variable is incorrect, but a valid image is still present. See the Recover from a Continuous Reboot section of this document for more information.
