I have a problem and I am hoping someone can help me. I got the DuoX3, I installed with out any problems, soldering that is. The chip works great. The problem is I flashed one of the banks with a new bios and the chip doesn't like it. The chip will not "ARM", it just goes to the MS bios (hold power button for 2 sec to arm it, tries to boot but the system turns off for a sec then come back on with the chip off). This xbox will not boot to the dash because of a bad hard drive, yes the original hard drive is fried. Also it will not boot a cd/dvd with out the modchip armed. I got a new hard installed and all ready working but I want to use a different bios. I still have the original bios that came with the chip on the other bank AND I WANT TO KEEP IT. My question is, since this has two banks for two different bios, can I switch to the other bank so I can "ARM" the chip and switch back the bad flashed one so I can reflash it WILE THE XBOX IS STILL ON. A sort of "how swap" trick if you know what I mean. I would go ahead and try this, but I don't want to damage the chip as in "oops, lost all the data in the mod chip so no more mod chip". Basically, I want to know if the bad flash is doomed or not. Any help would be great. THANKS!!!
