Emil sounds like a random reboot. Try looking for some program to erase the eeprom then flashing again.

To all that are having trouble after rebooting, try to change the ‘eeprom magic number’:

static const byte settings_version = B00000001;

Have in mind that the variable is a byte in binary format so it must have a total of 8 random 1 and 0 like this:

static const byte settings_version = B10110100;
