–My water monitoring station in northern Minnesota was cut down in its prime by beavers. It ended up half submerged and flooded with river water. It sat in the river for 3 weeks before I could make the 7 hour trip to rescue it. Since rescue I dried, toothbrushed and dried it again. Amazingly the LEDs come on when I plug it in and it connects by the libusbK port on my Windows system. But the beaver attack seems to have traumatized the electron and I can’t get past DFU mode.
–This is probably hopeless but since the electron seems to go into DFU mode, I thought I’d try to recover it. Symptoms are:
–When power applied,
red power LED on.
blue D7 LED on.
multi-color LED flashes multi-color for 2 seconds and then yellow (DFU mode)
I tried particle doctor at the CLI.
Device Doctor responds “Updating system firmware” and states the firmware update successful.
Device Doctor then responds “Flashing the Device Doctor app” and “Flash success!” but then reports “The Doctor didn’t complete successfully. Could not find serial device.”
I also tried using the CLI to flash the system over usb, The effort went:
G:>particle flash --usb system-part1-0.7.0-electron.bin
G:>particle flash --usb system-part2-0.7.0-electron.bin
G:>particle flash --usb system-part3-0.7.0-electron.bin
Even with all these successful flashes, I still only get the DFU mode.
Is there a step I’m missing or is the electron toast?
