D4V2 firmware flashing issue

I just received my flashing kit from Hank.

I have a problem : I tried to update my D4V2 E21 2000K with the following firmware :
anduril.2021-12-13.emisar-d4v2-nofet.hex

But the flashlight does not start; I have the aux led which lights up but nothing by pressing. I tried reseting but nothing.

I put back the old firmware that I had saved by reading through the kit and it’s all good again.

Any suggestions ? wrong firmware ?

Try anduril.2021-12-13.noctigon-kr4-nofet.hex

Yup, that is the fix.

This light uses a 5 amp CC driver, not the D4V2 driver due to the LED choice.

Thank, I will try this

That works thanks !

For my Noctigon KR1 W1 Yellow (Osram KY CSLNM1.FY) should I use the same firmware (anduril.2021-12-13.noctigon-kr4-nofet.hex) ?

That is a config I have never used and have never researched. I suspect that it will be no-fet firmware based on the drive current max for that led. So, if that is the case… you are on the right track.
