Boron in infinite loop of Purple to Yellow (DFU) to listening

Firmware
1

So we got it provisioned but could not get it programmed correctly. Then it started the infinite loop of purp, yel, blue listen, then SOS 8. So I did the evil deed of Unclaiming the device. Now it just seems bricked. I have downloaded CLI for my Win 7 but have no idea what to do. Any thoughts?

You can try this

  • make sure you got the antenna and the charged LiPo connected
  • put the device in DFU Mode
  • run CLI particle update tinker -v
  • put the device in Listening Mode
  • run CLI particle usb setup-done
  • put device in DFU Mode
  • run CLI particle flash --usb tinker -v
  • check whether device can now connect correctly
  • it not, put device in Listening Mode and run particle serial inspect and post the result here

BTW, SOS+8 (Out of Heap Memory) is an odd error for a fresh device. Are you sure you never flashed your own code to it?

I attempted to put it in DFU mode and it keeps going past DFU. No way to stop it. I held RESET and MODE and released RESET when flashing yellow. It goes to White quick flashing and then blue flashing (listening). So non-starter.

It’s got a bad mode button. Replicated same function on another working Boron by holding the mode button down at power-up.
