we are preparing for production of a device with a p1. the p1’s we have have a old device os (0.5.3) and the normal way to get them in dfu mode (“particle usb dfu”) does not work on these 0.5.3’s.
i keep “destroying” them (startup - no led, can get them in dfu mode with the buttons) - seems the default application is corrupted or something. i can flash them with 1.5.2 no problem
but it would be great if i could reflash them to “factory state” to try to fix my factory test
are these (old 0.5.3) system and application files somewhere to be found?
