This spell allowed me to stay in DFU long enough to flash 1.5.0, firmware that does nothing except serial out a counter. I reactivated my SIM, and I’ll remove manual connection as soon as I think the SIM has been activated so I can see if it’ll connect to the cloud.
I’m reading about 85-140 F across the device, 120F on the QR code, 140F down around C1.
I burnt my fingers putting into DFU mode and learned to use tweezers, but trying to do device doctor I get this:
> particle device doctor
The Device Doctor will put your device back into a healthy state
It will:
- Upgrade system firmware
- Flash the default Tinker app
- Reset the device and server keys
- Clear the Wi-Fi settings
The Doctor will operate on your Electron connected over USB
PLEASE DISCONNECT ALL OTHER DEVICES BEFORE PROCEEDING
You'll be asked to put your device in DFU mode several times to reset different settings.
Updating system firmware
Put the device in DFU mode
Tap RESET/RST while holding MODE/SETUP until the device blinks yellow.
? Select Continue when ready Continue
> Your device is ready for a system update.
> This process should take about 30 seconds. Here it goes!
! System firmware update successfully completed!
> Your device should now restart automatically.
Flashing the Device Doctor app
This app allows changing more settings on your device
Put the device in DFU mode
Tap RESET/RST while holding MODE/SETUP until the device blinks yellow.
? Select Continue when ready Continue
The Doctor didn't complete successfully. Could not find serial device. Ensure the Device Doctor app was flashed

Oh, and if I repeat the device doctor steps again, it says I’m in need of a system update. Rinse, repeat.
