Hello, i'm New to mod firmware for a Action cam. So i want to ask anyone here how to mod the firmware for the Firefly split 4k. I have read here some posts and topics about how to modifications of novatek firmware but i Don't know where to Start. Is there a chance to got a tutorial or anything Else to Do this?

I wanted to make some colorcorrections or a flat color Profil like nutsey has done it. Some brightness correction for brighter lens.

Many thanks in advanced,
Schimi

Unfortunately I've lost all of my Split 4K studies when my main HDD died several months ago. Good thing is my cam is flashed with the latest custom fw. But I don't know how to dump it as the flash memory is WSOP8 type which is not so easy to deal with.
