I don't think it's toast. It's still booting, obviously. I'm guessing that it blew some fuses and then stalled, causing the old dash to not boot up. What could you try doing is making stock dashboard images from your original image and flashing those to see which one boots up. That way you know specifically what fuses have been blown.
Little bit confused.. I've been trying to write my original NAND dump to the system and nothings booting... again, quite noob to the 360 haha, I'm more use to the simple Original Xbox ways.
