That’s what that guide is for, to make your computer recognise the photon. Give it a shot before writing it off prematurely.
Alternatively, have you given safe mode a try yet?
The reason the buttons don’t trigger a factory reset is because there is no factory reset on the photon, as documented.
@RickardP, I had similar issues in the past - Windows can be a pain. I ended up doing a few things:
Use a good USB cable
Removed ALL the Core/Photon devices and drivers I had on my system. To do this, I used these command in a small batch file:
Once in Device Manager, you need to show hidden devices to reveal all the unconnected devices. Open the “Ports (COM & LPT)” item to see the COM ports assigned to Particle devices. You may also see other drivers setup by Zadig. I then uninstalled all the COM devices associated with Particle devices, including deleting their driver files (check box on the uninstall).
After clearing everything, I rebooted. Then connect you Photon, ideally to a USB2 port, put the Photon in Listening Mode and install the Particle Windows Serial driver for the Photon. Do this by manually selecting the driver (not auto detect). Then, put the Photon into DFU mode and install the Zadig driver for it. Repeat for each device you have.
If after all this Windows dosen’t properly find the Photon on USB then I have no more advice (install Win 10?!).
Not any help but just an observation.
The device shown in your zadig screenshot does not have a valid VID/PID combination.
For a Photon you should see 2b04:d006
So either the device “forgot” who it is or you’ve got something wrong with the USB link (Photon socket, cable, PC port).
I remember some post where a member had a bent pin inside the USB socket.
