Wait a minute? So the ETC developers changed the algo to prevent E3 from mining on it and all it took was a firmware patch to get them going again? Pretty bad coming from the ETC devs part in my opinion. Congrats on actually being able to achieve this. At first I saw the thread and assumed you are some newbie trying to scam a few people but you seem to have some merits.
My advice is you try and contact that VoskCoin guy, he has a Youtube channel and he might make a review about your patch if you give it to him for free. He has a big audience there and his videos are entertaining to watch. He might have an E3 laying around his place somewhere to test it out on.
I have low participation on the forum because I moved everything to Discord. Much easier to communicate and offer support
