Factory Reset 9200L

[slyfoxx]

I've gone through several discussions on this board of different folks trying to reinstall or repair a corrupted ios. I'm effectively in the same boat but can't seem to get passed my issue. I've tried loading in ROMMON but can't seem to get it there. I've read holding mode down while plugging it in, hitting the mode button three times when the front LED blinks. I've tried booting from USB and TFTP. I can't access flash: because it's read-only. Can't access anything plugged into the USB, have tried several in FAT, partitioned to a smaller partition, just in case the size of the disk causes issues. I'm at a lost at the moment.

Below is what I see in flash:

switch: dir flash:

Attributes Size Name
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
drwxr-xr-x 4096 .prst_sync
-rw-r--r-- 4003 lateshutdown.log
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Currently using Terra Term for most of this and have used TFTP64 when trying to boot from TFTP. Any and all help would be great. Can provide more info if asked.

This is everything you have in the flash? Can I see the command "set" ?

switch: dir flash:

Attributes Size Name
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
drwxr-xr-x 4096 .prst_sync
-rw-r--r-- 4003 lateshutdown.log

I have not personally dealt with a 9200, but we use 9300s. I had a user format the flash years ago and I believe this was the procedure to repair.

boot to ROMMON, and then boot from a USB. The hard part here is they don't usually like large drives and I have a couple old 4GB USB2 drives in FAT32. Finding 4GB drives is a bit hard these days. Examples below, but change to whatever code you are installing.

boot usbflash0:cat9k_iosxe.17.09.05.SPA.bin

now, if I remember correctly you can't install from the booted file, so need to copy it to the flash.

copy usbflash0:cat9k_iosxe.17.09.05.SPA.bin flash:

From here you should be able to install and is should set the boot variable.

request platform software package install switch all file flash:cat9k_iosxe.17.09.05.SPA.bin auto-copy

**New code**

install add file flash:cat9k_iosxe.17.09.05.SPA.bin activate commit

If the switch is in ROMMON, post the complete output to the command "set".

Try to change the flash to RW, find the below post.
