I’ve had my Core for 2 years and it’s been running a simple code, flawlessly. Over the weekend it seemed to get stroppy and wouldn’t connect to the internet (flashing green light).
Following Particle docs, I tried to perform a reset through CLI. CC3000 & USB Tinker worked without problem but when I try to run >particle flash --factory tinker I get this :
>particle flash --factory tinker

Make sure your device is in DFU mode (blinking yellow), and that your computer is online.

I’m completely out of my depth with this and would really appreciate any help at all.
Yes it was working great for 2 years. I cannot complete >particle setup because it won’t connect to wifi to allow me to claim the core. Wifi credentials are correct.

I tried to flash my core again with a different computer with particle CLI installed. I still get a DFU error when I try to run this command >particle flash --factory tinker

The error is constant.
When I use >particle flash --USB tinker that completes but does not resolve the problem.
After that completes I am still unable to connect to wifi or flash --factory tinker
Try this…Take a deep breath. Don’t flash it.
Type:
npm update -g particle-cli
particle update
!!! I was unable to detect any devices in DFU mode...
> Your device will blink yellow when in DFU mode.
> If your device is not blinking yellow, please:
1) Press and hold both the RESET/RST and MODE/SETUP buttons simultaneously.
2) Release only the RESET/RST button while continuing to hold the MODE/SETUP button.
3) Release the MODE/SETUP button once the device begins to blink yellow.
Still the same symptoms :
When I "particle flash --factory tinker" I get this:

The CC3000 update works normally
The USB Tinker update works normally.
I still have a flashing green led and a core that is useless! Thanks for your help anyway
