I actually have done a massive amount of research but most of the instructions I’ve found are vague in some respects, sometimes they’re outdated, and sometimes they just assume too much. I’ve literally seen ones that say like “1. Unlock boot loader. 2. Load new rom. 3…. Etc” I was like “uh… how about any clue on how to do those things? Even a link to sub-procedures where it’s already documented.
I’m sorry to hear that you’ve had issues like that, I can imagine how that would be upsetting. If you do hit a roadblock like that, I’m sure that people can help if you post here. I only said my original comment because I didn’t understand the question right. I misinterpreted and thought that you were asking for something like my second comment, with every single device listed and a guide or something on how to root it. Guides really do vary in quality, and your mileage really will vary with them.
