Another video from, Tech James.
In Summary, he guides you through the whole process on how to setup the R4i Gold Plus. He clearly points out how and where to download the kernel and even how to extract the files.
In addition he also shows you how to transfer the files to your micro sd card from your PC or Mac.
He makes mention of the NTR Boot mode, that the R4i Gold plus is capable of launching for those who use this card to install custom firmware on the 3ds and 2ds consoles.
