Issue in Home Assistant on linux doing the update from v1.0 to v1.1.0 of the ZWA-2

I wondering if there is a step by step on how to finish/repair my ZWA-2 that is in bootloader mode?

Below is firmware to reflash

Did you get nvm backup
Before you tried update?

Hi tmjpugh,

No backup, it’s my first Z-Wave integration :sweat_smile:
Thanks to point the location of the firmware, but I need the command line to complete the upgrade.

I hope someone will have a solution.

Same problem
I think they had flash method

I guess in zwavejsui there is advanced action that will allow you to flash bootloader

Install this add-on.
