I was performing an IOS upgrade when we got hit by a major storm. We had a blackout in the middle of the upgrade and lost power. Now the switch just keeps restarting itself. I have provided below the screen shoot of what is going on:
Front-end Microcode IMG MGR: found 1 microcode images for 1 device.
Image for front-end 0: /tmp/microcode_update/front_end/fe_type_8_1 mismatch: 1
Front-end Microcode IMG MGR: Preparing to program device microcode...
Front-end Microcode IMG MGR: Preparing to program device[0], index=0 ...88424 bytes.
Front-end Microcode IMG MGR: Programming device 0...
% Front-end Microcode IMG MGR: address 0, Could not enable sys_poll
% Front-end Microcode IMG MGR: unable to program device: 0
% Front-end Microcode IMG MGR: malformed microcode cache
Waiting for 120 seconds for other switches to boot
Can anybody help me with this. I have tried to format the flash and no good. I have tried to reboot from usbflash and nothing. I come to you for guidance and help.
Thank you

what is the current version, what is the target version you try to upgrade?

So the current version was 16.6.8 and going to 16.6.9. As you can see below, there are no traces of 16.6.8, just 16.6.9:

Is the boots up or keep rebooting?
Looks like you hitting with Bug :
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCva30394/?rfs=iqvred
Contact TAC for RMA here i guess?

Agree with @balaji.bandi and it could be CSCva30394.
Is the switch boot into ROMMON? If it is, download any other IOS-XE version, like 16.9.10, and then proceed to load the firmware using emergency-install.
If the switch boots 16.9.8 successfully, then downgrade to 16.6.10.
If the switch does not boot into ROMMON or does above method does not work, contact Cisco TAC and arrange for an RMA.

You need to go into ROMMON and "set BOOT_LOADER_UPGRADE_DISABLE=0"
