I have an electron that appears to be stuck in DFU mode - yellow flashing. When I remove all power and reapply power - USB power and/or USB + battery - it come up in DFU mode. Pressing the reset and / or mode button have no effect - always returns to DFU mode.
particle flash --usb tinker -v
particle update -v
all give the same errors message
Error writing firmware: dfu-util: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!
dfu-util: Error during special command “ERASE_PAGE” get_status
Since I can not get the device in “listen” mode - blue flashing, I can not attempt to reload the boat loader. I have been through the community suggestions and attempted all suggestions but always end up in the same place.
