Well I'm wanting to install the custom kernel with the jtag hack. But my 360 is on the latest kernel, however I'm looking to purchase a banned 360 to install the custom kernel on. Because, well, they're cheaper. And an unbanned 360 with the custom kernel is likely to get banned anyways, and a banned 360 is more likely to have an exploitable kernel version since it can't update from LIVE.

So once I get a banned system, what would I need to do to get a flash dump?

Also, if anyone has a banned 360 with the exploitable kernel they want to get rid of, let me know.
