Hi...i am also facing the issue. I tried using different USB cables,and removed all other USB connections from the PC. Nothing changed. I'm beginning to think the Pandwarf is not communicating with the PC for purposes of updating the firmware.
I have a PandwaRF (unbonded) with Nordic FW 0.10.1 and get in the app every time a message that 0.10.3 is ready. So I go to FW, press Update Firmware, and the following happens: 1) PandwaRF will be disconnected during update [OK] 2) Initializing DFU process... 3) PandwaRF turns off and app says (X Disconnected) 4) Waiting for bootloader... 5) Connecting... 6) (X Gollum firmware update failed)
I can press SW5 while in at step 5), then the process goes back to step 2).
Recovery procedure doesn't work anymore as the newest FW there is 0.10.0...
