Bootloader upgrade to 02.04.0005 fails with CRC error

[aLiEnHeAd]

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"

I updated to the latest 5.0.2 nightly and added the following patch to
/opt/z-way-server/automation/modules/ZWave/index.js

after that I succesfully updated the bootloader and then I updated the firmware from 7.42 to 7.46
Now my RaZberry 7 Pro is bricked

When I start the Raspberry Pi no LED activity on the RaZberry...
I really hope I can bring it back to life. Any ideas?



here's the patch I got from PoltoS:
