We recently pushed out an update to our Photon-based devices and maybe like 10% have died. I just got back the first one (we’re having to replace them) and the only thing I can get is safe mode or DCA mode. I can get it to DCA mode and download the firmware by wire but cannot get it out of safe mode after that.
My first concern is that it happened at all. Seems doubtful it is a coincidence. At first I was guessing that the power supply was inadequate to burn new firmware – so it would work just fine until the PS was taxed – but the power supplies we use are rated 500mA which I believe is USB standard. Next guess is that if a customer has an iffy WiFi, that the update was interrupted and it corrupted the firmware. I’m guessing here. Ideas?
My second concern is getting the bad one(s) to work again. There is not “factory reset” on a Photon so how do I totally start from scratch??
