WS-C3650-24TS-E USB Boot

Hi, 

So here is my issue...

I need to update the firmware of my router. To do this, my manual requests to remove the old one before and copy the new one with TFTP. I don't know what happen but the TFTP was not working on the server i received the request but on the router he was already showing that the transfer was failed. 

I know that there is also the possibility to copy the new firmware from a usb key. When I try I received this message : 

 

Booting...call dfs_loadpartitions, retry = 1
call dfs_loadpartitions, retry = 0

usbflash0: contains unexpected values in partition table or boot sector.
Device needs formatting before use!

Interface GE 0 link down***ERROR: PHY link is down
flash:/cat3k_caa-universalk9.16.09.03a.SPA.bin: no such file or directory
Cannot open file flash:/cat3k_caa-universalk9.16.09.03a.SPA.bin

The system is unable to boot automatically. The
BOOT environment variable needs to be set to a
bootable image.

 

I format my Usb key in different format (NTFS and FAT32) and used different brand however I still received this message or the ubs key is not detected... 


Do you know a solution to copy the firmware of the switch with a USB key ? 

 

Thank you by advance for your help !
