@MHM Cisco World So to reset the 3110 ASA, can we give 0x20?

Make sure you have the backup of the running configuration prior following the given steps.

After changing the confreg value to 0x21, I am getting the below screen after rebooting. Not able to break it to get in rommon and even not able to do factory reset by pressing the button in ASA.

Try cold reboot the device and see if you are able to break into rommon post that.

for cold reboot perform below steps:

1) power off the device physically.

2) remove the power cables and wait for 5 mins.

3) replug the power cables and switch on the device.
