I don't find this to be that hard, what I find is most people don't bother reading. You can tell by the number of people with Old 3/2DS's that keep saying it doesn't work on their. (no shit, it says for New 3DS only), people who can't bother reading all the help in the various threads, since most problems people been having have been discussed and figured out, and yet people keep asking the same questions over and over.
People, learn to read. Take your time. Go thru the threads. Use your brain. And if you don't like the steps or aren't sure, then don't install it. We still have 2 other methods of getting Gateway working on our New 3DS's.
Me, I've been taking my time. Like all updates, I wait to see what everyone else has to say. This time waiting really paid off because Gateway did another update that made it even easier (don't need to take my mSD out now). So unless there is another update today, I'll probably install the MSET exploit this weekend.
Those that English is a second language, well, I can understand why it would be a bit harder for you, English sucks and Gateway instructions appear to be written by someone who English is a second language.
