You can do one thing there. Power off the switch and power it on again by holding the mode button on the switch. Hold the mode button for approximately 15 - 20 secs from the power on until you get the "switch:" prompt.
Once you are in "Switch: " prompt, enter the following commands "flash_init" and "load_helper".
After this do a "dir flash:" to see if you have any image on the flash device. If there is an image then boot that image using the "boot flash:imagename".
