As some of you may know, my Nitecore D11 went poof a while ago and after the past few months of discussing the return of the light to Nitecore for warranty repair/replacement the outcome is that I don't have proof of purchase and they're not accepting it under warranty. So, I threw in the towel and opened the head on the light up the other day to have a nosey around inside and see if I could find what exactly went wrong with it. So far I've discovered that some of the small components (I believe they were SMT resistors) on the battery terminal side of the board are missing - how this happened I have no idea but that's probably what went wrong with the light. I also know that the LED works, I connected it to a 3v source briefly to make sure that it was illuminating, so I have an XP-G R5 led on a 14mm board for my spares bin. I have the spring and brass heatsink, reflector and everything else that the light is made up of - it's fully disassembled. I was thinking of buying a new driver circuit from kaidomain and building a new light using the bits that I have. I've no idea what I would build though. There seems to be a nice 5 mode AA/AAA 13.5mm driver circuit on KD (see below) but how could/should I switch this if it was installed in the head and heatsink of the D11?
Any help would be much appreciated folks - so far my only experience with building flashlights has been adding dropins/different bodies/different bezels to existing lights

As promised, here are pics of the driver board:
As you can see, there are some components missing from the front (battery terminal side) of the board. At least two SMDs are missing from what I can see - C3 and R9. There also seems to be a 3 pin component missing from the board at about 4 o'clock, a voltage regulator perhaps?
