In the z-wave.me -> trident upgrade instructions it says
Make sure to install the latest firmware in your Z-Wave radio module. For this, navigate to Firmware Upgrade page and upgrade to 7.42, then upgrade the bootloader to 02.04.0005, then upgrade to 7.46, and finally to 7.47.

I successfully updated the firmware from 7.28 -> 7.36 -> 7.42
But updating the bootloader of my RaZberry 7 Pro fails: "Unable to update data. /ZWave.zway/ZMEBootloaderUpgrade"
