Unable to flash Conbee II firmware

I’m unable to flash by Conbee II stick to the latest firmware. Tried rebooting and switching USB ports, but the error message stays the same:

Running the device on a headless Debian 10 install on bare metal.

Can you try to flash this firmware on a windows PC? You can download GCFFlasher here: Index of /win/

the procedure is nearly the same: https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Update-deCONZ-manually

I’m sorry, but I don’t have a Windows pc at hand. Only machines running Linux and Mac OS.

Sry, my bad. It is of course also possible on Linux (Ubuntu/Debian).

Hm, but isn’t that what I tried already?

sudo GCFFlasher_internal -t 60 -d /dev/ttyACM0 -f deCONZ_ConBeeII_0x26720700.bin.GCF -x 3

I am just curious if it works on another sysystem.
Edit: Or you already tried this on Ubuntu? I assumed your system was a RPI.
I see, you wrote it in your first post… well lets see…

Ok antother try. I asked another developer and he said that problem could occur with the new firmware and GCFFLasher v3.xx

You could try GCFFlasher v4 (https://github.com/dresden-elektronik/gcfflasher) but you have to download the source and build it on your system. There is a manual at the github page.

Or you wait until deCONZ 2.13.0 is released it will contain the new version.

Or another option is to try to install an older fw version with GCFFlasher v3.17. e.g. 26700700 or 26680700 (Index of /deconz-firmware/)

Is there more of these “known” issues? As a community, having a list of known issues and - more importantly - workarounds is key.

Thanks, I’ll just wait for the release of 2.13.0 and report back.

Not really. I just have this information from @manup. I hope the problem just disapears with the new GCFFlasher.

So finally updated my Debian system to version 2.13.01-debian-buster-beta. Unfortunately, updating the firmware to build “deCONZ_ConBeeII_0x26720700.bin.GCF” still fails.
