I have several Photons and all are working as expected on this network/router less one. This Photon was working fine September 2017 and then sat unused until yesterday. When I powered it up yesterday it failed to connect and was fast blinking cyan with intermittent red flash. I assume I have a corrupt key but have had no luck resolving that. Feedback welcomed.
I tested the following;
uninstalled CLI reinstalled new (win7 installer)
Particle update, success, still flashing cyan/intermittent red.
Particle doctor [failed at very end with “New key created! The Doctor didn’t complete successfully. undefined”].
Firmware 0.7.0, firmware flashed from CLI (part 1 & part 2), success, still did not connect to cloud.
reflashed bootloader-0.7.0-photon
flashed clouddebug.bin from rickkas7;
