Unable to flash firmware past 2022

[e1w00db1ue5]

Hi,

I'm unable to flash any firmware past 2022, I am using V4.04 for all of these test.

I get the following message;

C:\GCFFlasher_Win_V4_04_00\GCFFlasher_Win_V4_04_00>GCFFlasher -d COM3 -t 60 -x 3 -f deCONZ_ConBeeIII_0x26450900.bin.GCF
read file success: deCONZ_ConBeeIII_0x26450900.bin.GCF (174270 bytes)
flash firmware
connect \\.\COM3, baudrate 115200
command UART reset done
connect \\.\COM3, baudrate 115200
query bootloader id V3
query bootloader id V3
query bootloader failed
retry: 56 seconds left

I did notice when using older firmware it would say "query bootloader id V1".

When I try to do GCCFlasher -r -d COM3 to see the versio number the only output is;

connect \\.\COM3, baudrate 115200
command UART reset done

Any advice is helpful, this is connected via USB extension cable direct to my Windows 11 PC, tried different ports but as I said, earlier firmwares appeared to flash ok.

TIA

Same issue as the original poster.

[manup]

Is there already a working firrmware on the ConBee II?

Can you please try again with a following sequence:

• Unplug ConBee
• Run the command GCFFlasher -d COM3 -t 60 -f deCONZ_ConBeeII_0x26780700.bin.GCF
• Attach ConBee

This forces to reboot into bootloader mode after attaching. And should make the update work, in case a protocol firmware reset isn't working.
