For some reason, all of the image files on my C3560CX-12PD-S switch got corrupted so when I reset my switch, it would not boot to an image file. I tried copying an image file several USB drives to the flash but was unsuccessful. I received the output attached. Are there any other ways to get the image file onto the switch?
is the USB formatted for FAT32 ?
Try FAT16 to i think only some switches support that in rommon
Also not all USB models are supported try another one as FAT32 if you have any spares just in case
