That's just a sort of BS again... OMG I know why i left the 360 scene.. Damn.
What they offer will NOT work, or work at least for some weeks and then its done!! That littly tiny Mainboard is such a bad manufactured thing, its not reliable! And for those dont trust me... I know the manufacturing company for the 360Key and their dumb MB. I know that guy a long time and get a sample of him.
DONT TRUST THIS!!! You will be screwed within 1-2 MONTH!!
Stay on Jtag or flash your drive but stay faaaar away from that Moneymakin BS!!!
(YES, 360KEY team remember us)
