I’m having trouble with some code that works fine on 0.4.9, but doesn’t seem to run on 0.5.0. I setup a new photon, and it updated to 0.5.0, and I noticed some issues. I upgraded my working version to 0.5.0 to see if I noticed the same issues, and I do.
I now want to downgrade to 0.4.9, but can’t seem to do that. If I enter dfu mode and manually flash 0.4.9, it works, but then the Photon resets and I see lots of flashing magenta, which I believe means it’s updating to 0.5.0. When I enter setup mode after that and do a serial identify, it reports 0.5.0.
I guess I’m not positive it’s updating back to 0.5.0 immediately, but the 0.4.9 flash seems to work, but then it’s back to 0.5.0.
I’d prefer to disable automatic updates, as I don’t want devices in the field to stop working if I have a firmware-related issue in my code.
