This guide will utilize Z-WaveJS UI to set your Z-Stick 7 into bootloader mode, and how you use this mode to downgrade your Z-Stick 7 or Z-Pi 7.
You will need access to Z-WaveJS UI to perform these steps either through Docker or Home Assistant.
It is recommended, that if you do not have a backup of your Z-Stick 7, make sure that you create a backup in case anything goes wrong.
1. Download the attachment "SLUSB7000A-bootloader-nolimit.gbl", and use this to firmware update your Z-Stick 7 / Z-Pi 7.
This will cause your Z-Stick 7 to go into bootloader mode once the firmware update is finished - ZWaveJS UI at this time will not be able to connect yet.

- Click UPDATE (under firmware update OTW)
- Choose the file "SLUSB7000A-bootloader-nolimit.gbl" (Which you downloaded before finishing this step)
