OTA update of 0.8.0-rc.4 app on 0.8.0-rc.2 device


I had trouble performing an OTA update of an 0.8.0-rc.4 app on two devices today that were running 0.8.0-rc.2 with an older version of the app.

It would enter SAFE MODE after the update. I manually placed it in SAFE MODE and tried again with no luck. Also tried to download Tinker 0.8.0-rc.4 with the same result (entered SAFE MODE).


Solution was to OTA 0.8.0-rc.4 system firmware only. At this point, the device came up as expected, running the new app.

OTA Firmware update trouble
Photon stuck in safe mode while upgrading to 0.7.0

How do you OTA update the firmware only?
I tried with particle CLI, but after flashing system-part-1 the device is no longer online, so I cannot flash the other parts. (Using a 3rd party SIM).


Did you wait long enough between the flashing system-part-1 and the next part? It can take some time.
