Upgraded to 1.3.0-rc.1 using build.particle.com y cannot downgrade to any other firmware available.
This is the first time I had this problem. I need to go back since upgrading I don’t get the blynk library to work correctly.
I tried this on another Photon with a basic program (don’t use any library) and have the same results.
Is this a known problem? Is there a way to fix it using web interface? It isn’t easy to access them from USB.
