Hey so i have some original particle cores that use to work like a dream. I last plugged the one in in july and all was good.
I tried to revived it today and it just flashes slow cyan and wont connect. I cannot get it to change to the flashing blue light.
I can get it in to dfu mode and run particle upgrade and it says there is no updates available for it.
Ive tried doing a hard reset and that doesnt change anything different.
Any ideas on how to revive it?
