Photon flashing yellow after powerup, particle CLI cannot load firmware

I’d appreciate any help updating my firmware.

When I plug my Photon to the USB port, it starts with no lights on (except the D4 LED that is constantly on). Then it enters flashing yellow. I cannot update its firmware using Windows CLI particle.

C:\Users\k>particle --version
1.47.0

When I run particle device doctor, it asks me to put the device in DFU mode, which it is, and I press Enter. It stays for about 4 seconds on the line saying “updating system firmware on the device…”, and then gives up with an error as shown below. After I hit enter, the device shows a solid yellow (not flashing) for about a second, then again starts flashing yellow.

C:\Users\k>particle device doctor

You’ll be asked to put your device in DFU mode several times to reset different settings.

Can you try this

particle update -v
particle flash --usb tinker -v

Thanks for getting back to me. Here’s the log. (more comments by me way at the bottom after the tinker load attempt)

C:\Users\k>particle update -v

Flash success!

The status LED light went dark (D4 LED constantly on) after tinker load.
I can see very tiny blinks of red on the status LED, but mostly dark.
After about 16 seconds, it starts blinking yellow again.
