Particle Web Device Doctor fails to create a backup file of the user firmware

Hi,

I've been trying out the Web Device Doctor with a Boron and Chrome on macOS Sonoma 14.7.1. The tool flashed the doctor firmware & Device OS 6.3.3 fine. I was able to download the cloud debug logs using Chrome and also view the logs via Particle CLI "particle serial monitor".

However, a backup file containing the user firmware was not saved in the "Downloads folder", as per the Device Doctor documentation. On attempts to restore the original firmware on the Boron, the Device Doctor instructions gave an option to "Restore firmware from backup file" but there was no "firmware_xxxx.bin" file for selection.

Has anyone come across this issue? Thanks.

I'm sorry; a backup isn't actually created in web device doctor mode and the message is incorrect and has been fixed. Unfortunately since a backup wasn't created there isn't one to use for restore, but you can flash your original source again for a sandbox device. For a product device, disabling developer device mode for the device or using lock and flash can be used to restore product firmware.

Hi Rick,

Thanks for removing the incorrect message in the "Device Doctor" documentation. I successfully restored my firmware using J-link.

@rickkas7,
Is the source for the Particle Device Doctor firmware locked down or available? Thanks.

The actual web device doctor firmware source isn't public, but it's a modified version of the cloud-debug firmware which has many of the same features.
