Recovering from a Software Failure

We just got our shipment of 3850 Switches in and Im upgrading all of them to the latest IOS and its a real treat to do. If you were use to doing it via tftp you will be blown away on how easy it is.
Steps
1) Down load new IOS-XE bin file from Cisco
2) Save it to a USB drive. Usb Drive must be formatted with FAT16 or 32. Mine was 32
3) Plug into 3850 Switch
4) dir usbflash0:
5) Make sure your IOS is there. "cat3k_caa-universalk9.SPA.03.06.02a.E.152-2a.E2.bin"
6) copy from usb to flash "copy usbflash0:cat3k_caa-universalk9.SPA.03.06.02a.E.152-2a.E2.bin flash:"

8. Run the command Switch#software install file flash:cat3k_caa-universalk9.SPA.03.06.02a.E.152-2a.E2.bin switch 19) When is done doing the upgrade you will need to clean up the old files that are in flash
