Unable to flash conbee 2 on windows

deCONZ General Support

Hi, I can not upgrade my conbee stick

I have downloaded the latest GCFFlasher and latest software but I have this error ‘query bootloader failed’ every time

logs:

GCFFlasher.exe -d COM3 -c -t 100 -f deCONZ_RaspBeeII_0x26780700.bin.GCF

I don’t have deconz running on this computer but i did try to upgrade the stick from deconz that is running in a VM a couple of times before realizing it could not work.

Any help would be appreciated

Hi,
for the usb stick you have to use the firmware for conbee2.
Should be: Index of /deconz-firmware/ → https://deconz.dresden-elektronik.de/deconz-firmware/deCONZ_ConBeeII_0x26780700.bin.GCF

And check the documentation for firmware updating.
