I'm afraid this is a situation where no one can hold your hand and guide you through the process. If you want to help, you'll have to educate yourself to be able to achieve it. You can learn an awful lot, but getting up to speed requires great motivation, patience and plenty of time. This is especially true in the case of the Nano 2G, because of the encryption.
Basically, if it were simple enough that someone could tell you what to do to get things going, they would already have done it.
