Stuck, can't set wifi credentials on photon ('s)

Firmware Device OS
1

I’ve got 5 or so photons laying around, the symptoms are the same for all five. when connected to a windows 10 machine the photon blinks green, I can hold the setup button to get it to blink blue and can get into dfu mode, so im able to run commands in the particle-cli, and am also able to communicate via serial. To date i’ve uploaded 2.3.1 bootloader, system parts 1 & 2, as well as tinker on 4 devices but no joy when I try to load wifi credentials.
This has been an issue for me in the past when a device has been sitting on the shelf for awhile but usually particle doctor seems to work. This time not so much despite repeated tries, This is true of all four of the devices i’ve got handy, ive got a programmer but unfortunately no workin photon to use it with. I’ve scoured the web for ideas but have come up short, help please!

edit- forgot to mention that when I try to do a setup with the app on my phone I get as far as connecting to photon then error’s out

If you hold the SETUP button down while plugging the device into USB, does it blink magenta (red and blue at the same time)? Continue to hold down SETUP. Once it blinks yellow, release SETUP. If it stays in that state, you should be able to use web device doctor to restore it.

Alternatively, when using the Particle CLI and the device connected to USB to your computer, can you force it into DFU using:

particle usb dfu

If you have the programmer shield for Photon you can restore it using JTAG/SWD, but that will be more difficult.

I holding the setup button whil plugging into the computer results in "an error occured while attempting…ect
I also was not able to force it into dfu mode thru usb

Ok, I guess I didnt know that these devices either don’t like or don’t do 5Ghz, I switched from 2.4 to 5 some time ago due to local congestion, didn’t know photon won’t play that way.
Thanks though

The P2 and Photon 2 do both 2.4 GHz and 5 GHz, but yes, the Argon, P1, and Photon are 2.4 GHz only.
