wallace at anypoint did you flash anything to 0x0? as i had this same issue when i tried to debrick the old one. (simply put the partition table was bad.) though before you tried did you make a backup of the devid? (cause you can safely flash teh backup found floating around the partition table. here to safely recover)
if you manage to do that and kernel let it sit for atleast 12hrs. thats how i got mine to finally boot when i ended up w/ a blank rootfs & Bad partition table.
