Bootloader bug in Device Restore USB in Argon

Firmware
1

When I use the Device Restore USB utility to update firmware on my Argons, the utility does not upgrade the Bootloader. Is this a known bug? I have a client who needs to update firmware on many Argons, and they are going to blinking dark blue because the bootloader was not updated during the upgrading process.

I tested this with a couple of Argons by updating the default Tinker user firmware from Device OS 4.1.0 to 5.9.0. Here is how I tested:

Start with Argon on Device OS 4.1.0 with default Tinker program AND no WiFi Credentials saved. Inspect dependencies (all good):

Use Device Restore USB to upload the default Tinker program on Device OS 5.9.0

After complete, inspect dependencies again.

Shows the bootloader did not update to version 2300 or greater, which is required for this to run.

When I update using CLI commands, the bootloader updates fine:
particle update --target 5.9.0
particle flash --local tinker

On Gen 3 devices, Device Restore DFU would sometimes not restore the bootloader when the target Device OS version was 5.3.0 or later. This should be fixed now.

Thanks for the reply. Do you mean it was just fixed, like today?

If I'm going from Device OS 4.1.0 (or earlier) to Device OS 5.9.0 (or later), then the bootloader should get restored to the correct version?

Yes, the bootloader will be upgraded or downgraded when going in either direction now between 4.1.0 and 5.9.0 on Gen 3 devices.

Fantastic...I just tested and it's uploading the correct bootloader version now. I think I see a new message in the tool that displays "Flashing bootloader" as well, which is a nice additional confirmation. Thanks for fixing that so quickly, @rickkas7
