Can't update Electron firmware from Windows [Solved]

Troubleshooting
1

Hey there all, here’s my environment:
-Win 7 machine
-Electron at 0.4.8 firmware currently
-Electron in DFU mode (flashing yellow…but the red portion of the LED is also flashing)

I’m following these instructions to update to v0.5.3 firmware:

Zadig reports that my device is running WinUSB v6.1:

Particle CLI is reporting the following when I try to push the part1 and part2 binaries:
“Invalid DFU suffix signature
A valid DFU suffix will be required in a furture dfu-util release!!!
No DFU capable USB device available”

Where could I be screwing up?

Try doing:

dfu-util -d 2b04:d00a -a 0 -s 0x8020000 -D system-part1-0.5.3-electron.bin
dfu-util -d 2b04:d00a -a 0 -s 0x8040000 -D system-part2-0.5.3-electron.bin

No luck, same feedback.

You could try another driver via zadig.
I have good results with libusbK

And as @nrobinson2000 pointed out the Electron needs 2b04:d00a - you’ve used the Photon’s PID d006

Tried it with libusbk - same message “No DFU capable USB device available”

6

Can you repost your actual command and error message?

7

I copied nrobinson2000’s lines into a cmd file and ran it.

parts 1 and 2 of the firmware binary are in the same directory.

8

Maybe you can try another USB port and other USB cable.
Can you also post a screenshot of your DevMgr showing the device?

9

When loaded with libusbk the Electron appears here in the Device Manager:

When loaded with WinUSB it appears here as Photon DFU Mode:

Okay I found a successful combination by switching the USB cable, USB port used and then back to WinUSB. It still reports an invalid DFU suffix but I suppose that’s normal? Thanks all!

@pNrie, I guess you deleted all your posts since you found a solution?
Instead of editing away what you wrote earlier, it might be good to know what you found to be the reason and the solution - even if it was on your own side :wink:

@ScruffR Yes, sorry, the original question posed by @markjones.cpe looked like the issue I was having and after an hour of debugging I was certain it was. Turned out to be a faulty *.bin file I was trying to load to the Electron via CLI and had nothing to do with the original post. I thought it better not to embarrass myself or distract from the original issue.
Maybe it should be possible to delete posts to the forum altogether?

It is possible to delete your own posts.
You should find a dustbin icon in the bottom line of your posts (maybe hidden behind the … ellipse) - but honesty isn’t embarrassing and might help others who fell for a similar misconception.

I agree with @ScruffR, I feel like this can be helpful for others and if you don’t want to delete it, you should leave it up. I’m glad you were able to fix the problem @pNrie!

Tis true, the dustbin hides under the ellipses
