Like I said before, sounds like your tsop

...Best bet is to do what HackDaBox said. And yes, you can boot a retail bios from the chip and use it to go on live without getting banned.
If you get a regular duox2 (2 banks, cromwell or the blue), you can wire up an external bank switch and flash one bank with hacked and one with retail.. Or you could buy a slightly more expensive chip like the x2.6CE that already has an external bank switch...
