Cisco 3850 Recovery

[waubie]

I'm currently experiencing an issue where my 3850 is no longer booting with the IOS is goes directly to the switch: prompt.

When I do a DIR command it doesn't show the Flash: directory.

I tried to perform the Flash_Init with the Emergency-Install using usbflash0: with no luck.

It comes up with no such device for the Flash.

The USB is working I'm able to do a listing of the contents.

Is it possible that the IDE drive is corrupt?

Thanks

here is the guide to recovery from Switch: prompt

make sure you formatted the USB  right format, try use differnet vendor USB if not working.

The USB is working fine, and I went through the recovery procedure.

The problem is that I don't have any Flash: directory when I perform the DIR command at the SWITCH prompt

[balaji.bandi]

1. Boot from usbflash0: and after successful boot from usbflash0:

2. Format flash:

3. Copy the IOS XE what you looking to upgrade from usbflash0: to flash:,

4. change the "boot system switch all flash:version.bin.

5.reboot
