LEDVANCE PLUG EU EM T not updating

[MirkoKas]

Similar to #941 I have a couple of LEDVANCE Smart Plugs (PLUG EU EM T - indoor) that show a new update to version 0x03483712 within Homeassistant (ZHA), but are impossible to upgrade. HA reports after reaching 100% that the file is invalid.

Sorry for the few information. Not sure what else could help here.

Same here.
When I try to upgrade the firmware of my LEDVANCE smart plugs (Zigbee) (from 0x033d3674 to 0x03483712. ), I keep getting a problem. The connection is fine as the upgrade moves to 100%, but then I get the error: Error during service call to update.install: Update was not successful: <Status.INVALID_IMAGE: 150>.

I have reached out to Ledvance, there answer was: https://www.youtube.com/watch?v=v7ERyT31KCM
when I metioned it should be done via ZHA their answer was: "At the moment it is all that we can offer. You could reach out to the HA community for assistance."
