Update firmware on leviton decora zwave switches

[NoWon]

I followed this process

Z-wave Switches Failing

I have had 2 Leviton DZ15S-1BZ Decora Smart Switches go bad (quit working completely) in the past 2 weeks or so. Weird thing is that they were both in the same location. One went bad and I replaced it and now it has gone out. Won't even turn on the lights. The first time, the lights were on and I had to replace the switch late at night to get them off. Does anyone have any idea what might be causing this to happen? Thanks!

but there is also this file you can use from Leviton you will still have to use the process above and use the Hubitat stick
