You saying you've spent years with 0 progress on such matter directly means you're not capacitated for this kind of things; a fish will never be able to climb the Himalayas so long as they remain above ground without liquid water even if it spends years trying to leave water.
And also, you've "spent years", but I learned that stuff soon after I started learning modding. Noone ever spoonfed that info to me; so I wonder wether this is ineptitude or you just lied to try to be spoonfed.
Yes; spoonfeeding means to have someone do something for you, because you are not capable of doing it yourself.
Modding consists on testing, trying and acquiring knowledge through public sources and by investing time; those who get spoonfed don't learn and don't develop the right mindset to become modders.
Learning about Arm assembly will teach you how to write and code in assembly, aka, how to write the instructions you need. The way to learn will be reading. Assembly languages are a niche because are meant to be used by computers; don't expect thousand videos explaining and spoofeeding up to the smallest detail as happens with common languages like python or c++.
