Hard Fault blinking red sos, can't get into safe mode

Troubleshooting
1

Hey everyone,

I am trying use ParticleDev. When I try to flash and it says “Flashing via the cloud…”, it comes back with an “undefined…”

The device looks to be blinking 1 time after the SOS. I can get into DFU mode (blinking yellow), I see it blink magenta but when I release RESET it goes directly to the red hard fault.

What should I do with this blinking red hard fault?
Thanks.

Try DFU Mode with

npm update -g particle-cli
particle update
particle flash --usb tinker

particle update

particle flash --usb tinker
running dfu-util -l

Error writing firmware…dfu-util is not installed

I’m following Tutorial: Installing DFU-Driver on Windows [24 Feb 2015]

I have Zadig and installed the libusbK driver on Photon DFU Mode. I could not find CORE DFU.

I still need the dfu-utils, which I would expect to be in the installation…why do they need to be distributed separately in this strange .xz which I am unsure how to install/uncompress, which the tutorial link doesn’t detail installation instruction.
https://s3.amazonaws.com/spark-assets/dfu-util-0.8-binaries.tar.xz…
7zip was able to open the archive, i copied to a path and added that path to env path.
particle update now succeeds and particle flash --usb tinker also work.

So my bad code actually requires me to flash a new firmware…lol.

Thanks for the help,
