Hi
I was asked to reset an Cisco 3650, but when i started it up then it wont boot.
Is it possible to just wipe the flash, and then just download a new IOS image, and copy it over with usb to the switch?
Best greetings from Christian Josiassen.

- You don't need to wipe the flash completely , make sure that there is a bootable image on it : copy usbflash0:image.bin flash:

- Erasing flash completely is overkill , you may delete vlan database or core directory amongst other stuff (e.g.)

No, that is incorrect thinking.
Each IOS-XE version operates differently. Some leave crashlogs in the crashinfo directory, some in the tracelogs, some in the core logs.
The safest way to wipe an IOS-XE is the command "factory-reset all" and then use "emergency-install" to put the firmware back in.

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