Catalyst 2960L-8PS - Switch Fails to Verify MCU Firmware

Hi, I restarted Catalyst 2960L-8PS switch today, but the switch never came back up. I consoled in and found that the switch was constantly restarting. The error messages are:

 

1.) Verifying MCU firmware... Fail

2.) MCU firmware Upgrade Fail - failed to get MCU data

3.) Invalid parameter block. Using Mac address of 0:0:0:0:0:0

4.) POST: ACT2 Authentication: End, Status Failed driver class subsystem initialization failed.

5.) Cloud not get Msemi to gracefully enter recovery state.

6.) nand bad command - shows bad blocks

 

Here are the screenshots

Is there a way to recover the switch?

Only nand bad shows as available command.

Switch is in a limited ROMMON.
