I’ve just manually updated three of my four cores to the latest firmware using dfu-util on ubuntu successfully.
I’ve just fired up the last one, and it looks like I have a boot loop.
(1)flashes white for 3 seconds
(2) solid blue for 1 second
I’ve tried doing a factory reset, but I can’t get that to work (it won’t go to the flashing yellow stage).
Any ideas anyone?
