I have a problem with mine. I treid 3 clicks from off to get to the to the thermal config. After that light did nothing. On one moment I got it to do momentary with moonlight. But now nothing. The battery is 4.1 volt so that is not it. When I put it together it does give one flash. Have taken it apart for more then 10 min. in the hope it would get back to normal but, no. Also strange when I close the head there is a gap of about 1 mm.

What am I doing wrong?

Pay special attention to the driver retaining ring part. Sounds like yours could be loose.
