Anyone have a good speedhacked version of US0J for the 812s they can give to me?
A "good" speedhacked version? My speedhacked US0J will be just the same as your speedhacked US0J; there is no "good" US0J vs. "bad" US0J.
Just download the official US0J firmware and apply whatever hacks you want to it using the available tools...
I never could understand how someone can read and find about about speedhacking and then ask a question like that..
