Hello,

your switch is stuck in the rommon mode.

can you do a dir flash: and verify if there is any valid image available in the flash or not.

If not, then you would need to perform xmodem recovery. Use the following link:

Switch didn't boot the file because it's either corrupt of it's not "complete".  You need to do an xmodem upload with the proceedure posted by Pronoy.
