Photon losts its credentials!

@peekay123 @frlobo I will apply given solution post Photon setup flashing cyan with a “quick red burst” (now orange burst) [Solved] … it’s not convenient at all when photon has been cased in a difficult to access place…
If you have more explanations about brown out / flash-eeprom erase I’m very interested! I have not yet attached a debugger to photon, but during startup, does any erase/write operations are done on flash pages/eeprom containing credentials or keys?
