Cisco switch stuck at switch: prompt

[DAVID]

I mistakenly did the factory reset-all on my Cisco 9200 switch and now the switch is only showing the switch: prompt at start-up.  How do I get the switch back to where it belongs with no config  and booting from the packages.conf?

[Seb Rupik]

Hi there,

Does 

boot flash:packages.conf

...work?

cheers,

Seb.

[DAVID]

No.  Looks like the factory-reset all completely wipes out entire switch including NVRAM and flash: 

[Leo Laohoo]

The command "factory-reset all" will completely wipe the Flash and some portions of the NVRAM.  

The only way to put the firmware back into the switch is to use a USB thumb drive and the command "emergency-install usbflash0:firmware_filename.bin".

Emergency-install returns a command not found

Is the switch in ROMMON?

If it is in ROMMON, post the complete output to the command "?".

Boot the firmware using USB:  boot usbflash:filename.bin

Once the switch has boot into IOS, copy the firmware into the flash and unpack using Install Mode.

[balaji.bandi]

factory reset-all  - This command remove all config and IOS image.

Download image from Cisco or from Local Drive and copy to USB stick

switch: dir usbflash0:  ( check the image available on USB)

boot usbflash0:IOS.bin (IOS.bin the file you see on USB)

Install the image using install command.

Well ROMMON mode (SWITCH:) commonly comes after power failure or sudden shutdown or software upgrade, try this

switch: flash_init

switch: load_helper

switch: Dir Flash:

switch: rename flash:config.text flash:config.old

switch: boot

-------------------------------------------------------------------------------------------------

if switch didn't boot properly, then you need to reset the switch but you will loose all the DATA, to proceed follow below 

Step 1.

Connect up your console cable and power on the switch, whilst holding down the “mode” button:

Step 2.

Initialize the flash file system with the command: flash_init

Step 3.

Delete the config.text file from the flash directory:

switch: del flash:config.text

Are you sure you want to delete "flash:config.text" (y/n)?y

File "flash:config.text" deleted

Step 4.

Delete the vlan.dat file from the flash directory:

switch: del flash:vlan.dat

Are you sure you want to delete "vlan.dat" (y/n)?y

File "flash:vlan.dat" deleted

Step 5.

Reboot the switch and you’re done:

switch: boot

-------------------------------------------------

if still you are facing issue, then your FLASH file might be corrupted, you need to download a new flash file from your Cisco account and transfer to the switch via TFTP server, always use Tera Term tool to console switch you will get more options like XMODEM, YMODEM etc for transfer files
