what are the requirements for an unbanned nand dump?

[stuntpenguin007]

I have an xbox 360 that has the rrod and it way beyond repair.  I hope to find a new falcon to buy, and then check out the jtag hack.

If I dump the nand of my rrod xenon (fairly recent dash, haven't been on live in a month) would I be able to use one as a "dirty" flash that I wouldn't mind getting banned on, and a backup nand dump for just in case?

edit: And while I'm running around the newbie forum, as I cant seem to find it on any other forums,  when did the blocking update for the jtag hack happen?  I'm looking at refurbished 306s right now, wondering how long ago they should have been refurbished, to still work with the jtag hack.

as long as the console hasnt had the summer 09 update you can do the JTAG hack

to my understanding, that was released august 11th, so I should try find a falcon manufactured before july factoring in that they started using the new bootloader in a few consoles before the update.

Also, the cygnos Version 1 should be programmable with the 7 wire lpt thing right?  I should just be able to bust out the multimeter and figure it out.
