Yeah, bored thread, i just answer to try to not relate "JTAGged box" with bans. Is not a correct use
A JTAGged 360 probably can be safely connected to live... using several and clean "nands" (i.e. XD cards)
Not actually, because if you try to connect to live... it will force you to update... and this update will ruin your "exploit"... but we cant be sure what will happen in the future
Free JTAG, is innocent !!
