I'm guessing the problem people have with no WiFi using that method to root has something to do with the kernel that is flashed. It used to be the only method to get around the locked kernel in the MDL T-mobile update. There's another metro member used my guide in the Tmo root forum who has the same no WiFi problem. Would it be a problem to flash a different Tmobile kernel on the metro? Is there an odin flashable stock firmware for the metro? I've looked but can't find one.
