Help operating Fireflies ROT66: Narsil or Anduril?

Howdy all, I’m looking for some help here.

The good news is I found my long lost ROT66 that I bought five years ago. The bad news is that I don’t remember how to operate it.

According to google it’s supposed to be either Narsil or Anduril, but I can’t get it to match how either of those are supposed to behave. A single click from off turns it on in moonlight. Press and hold from either off or on goes to a high brightness for less than a second then to strobe.

Any ideas?

Firmware is (NarsilM Version 1.2)

Ramping (default setting, like the BLF Q8):

From OFF:

Single click for ON
Click + long press =starts from moon and ramps up
From ON:

Single click for Off
Long press = ramps up or ramps down
2x clicks =full max brightness level
3x clicks = battery check
4x clicks= lock out on/off (4x short blinks)
5x clicks= momentary setting
How to reset to factory settings:

Do the following clicks from either OFF or ON:

3x , 2x , 2x, press&hold (for 1.2sec) till 4 blinks… HAHAHA… you bet that was easy right!?

If you use ramping UI only, do not hold the button for over 8 sec, it will enter programming mode. If you are in it by mistake, do not click the switch, but keep pressing the button, to get out of the setting. Better to write that here, than to get completely lost.

Mode memory:
Yes. When you press and hold the button to ramp up the output, you can release the button to memorize this setting. Turning off the light with a single click, and enable the light again with a single click will bring it back to last memorized output.
Lock out:
4 clicks will put the light into Lock-out mode. Another 4 clicks to re-enable the light again.
PWM:

Not that I could notice.

Click + long press definitely doesn’t ramp. It is high for less than a second then strobe.

I tried the factory reset sequence but no response.

I did dscover that if I continue to do short clicks after turning on it will cycle through six brightness levels
