Hello.
I got Zebralight H600 MK III XHP35
Recently it stopped working on H-level. H has same output as M2 sub-level . And it doesn't have sublevels at all.Batteries are fine. I got plenty of different 18650. And another zebra works on H with them as expected.

Is there any way i can reset "brains" of light?
What can i do with that?
