Accidentialy deleted entire flash: on C1000

[aerrpunkt]

Hello everyone,

I just deleted the entire contents of the flash: on a Catalyst 1000 out of stupidity. A system message popped up during autocomplete and instead of tabulator I pressed enter after "delete /f /r flash:"

Of course, the system no longer boots, "error loading "flash:c1000...."

any chance of getting it repaired?

Thank you guys, any help is much apreciated

can you share complete console output after reboot? 

if it loads to rommon mode, you can use below guide (it is made to 9400 but should be the same for 1000 series).

this should work.

Thanks!

I already found this, but there are two issues. I've got no mode button on my C1000, and there is no flash_init option available.

that may because of new OS. you can skip that and try 

switch: dir flash:

also, you may need to upload matching OS to switch. first download the OS file from cisco downloads and prepare it for uploading, can use Flash drive (which is easier)

Thank you Kasun Bandara, really helped me out - appreciate that!

I was able to regain access to the switch. Afterwards i updated the firmware using this manual:

Log into the switch through the console port or a Telnet session.

(Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC command:

Switch# ping tftp-server-address
For more information about assigning an IP address and default gateway to the switch, see Table 3.

Download the image file from the TFTP server to the switch.

If you are installing the same version of software that currently exists on the switch, overwrite the current image by entering this privileged EXEC command:

Switch# archive download-sw /overwrite /reload tftp://location /directory /image-name.tar
The command above untars/unzips the file.The system prompts you when it completes successfully.

The /overwrite option overwrites the software image in flash memory with the downloaded one.

If you specify the command without the /overwrite option, the download algorithm verifies that the new image is not the same as the one on the switch Flash device. If the images are the same, the download does not occur. If the images are different, the old image is deleted, and the new one is downloaded. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message displays.

The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.

For // location, specify the IP address of the TFTP server. or hostname.

For /directory/image-name.tar, specify the directory and the image to download. Directory and image names are case sensitive. The directory is for file organization and it is generally a tftpboot/user-ID path.

This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite the image on the switch:

Switch# archive download-sw /overwrite tftp://198.30.20.19/image-name.tar
You can also download the image file from the TFTP server to the switch and keep the current image by replacing the /overwrite option with the /leave-old-sw option. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message displays.

to restore the HTML Directory.

One little issue I haven't fixed yet is that the WebUI shows some strange header, but the switch is operating normally
