Hello, I have a similar problem to an old old thread.
I tried updating firmware, and it took an extremely long time.
It seemed to have finished, but my color 1000 bulb no longer worked.
I tried to reset it, but it flashes bright/dim, instead of the normal red, green, blue, etc.
I read that meant it was in rescue mode.
BUT how do i fix this issue?
My bulbs are very old and I cannot find help on LIFX support site regarding rescue mode.
