@anotherthing, Me too. I've watched video guides in another language, I can understand certain bits and watch them perform the job so that I can easily follow.
Getting your user set up, the internet working, and so on is the hard part in jailbreaking the Japanese consoles. Especially with the 3DS ones where it does the 3D settings also.
