I have a few sealed Photons from 2017.
I get many weird errors trying to update firmware.
I've attempted running particle doctor and it says:
! An error occurred while attempting to update the system firmware of your device:
dfu-util: Warning: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release
dfu-util: No DFU capable USB device available
I am only able to see the device on my computer via USB when in DFU mode.
When it is in nominal mode, particle list usb returns nothing. It also does not show up in System Information on Mac or Device Manager on Windows.
Initially I set up the device with the phone app and it looked good, connected to wifi, the cloud. But when I tried to load tinker it just hung with the spinning indicator. In the console and Web IDE, I could see it. On both app and Web IDE, I could identify the device w the LED.
CLI attempts at flashing tinker (--usb tinker) return this:
Error writing firmware: dfu-util: Warning: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release
dfu-util: Error during download get_status
Web IDE attempt to flash return this:
Device is likely offline, has poor RF Signal, or is running debug firmware which does not support OTA. Please rule these potential issues out and try again.
At this point, I've attempted to regenerate keys and get it back on the web, but now it just blinks blue (not breathin).
Fresh install Particle 3.7.0. Attempted Intel Mac, Win10 PC, and M1 Mac.
I'm stumped. What am I missing here?
Update: I opened another sealed Photon. Similar situation (except this one is still connected to the cloud).
