SBG6580 twerking help

Hi all,

I am a newbie to this forum but not to werld of console, phone, misc electronic tweaking and twerking. My question is what do I need to gain access to my modem for modifying? Is jtag the only way or can gain access via ethernet connection/network.

I have done some searching but my ADD has me going in circles trying to make sense of it! A tutorial would be awesome if someone could please point me in that direction.

Short story is I want to change my docsis 2.0 modem to a docsis 3.0 and I need to change it's mac.

thanks
