OK my portable hotspot is essential to my home setup. After this upgrade, or downgrade rather, I lost all functionality of my hotspot. Does anybody know how to root with this so-called upgrade? I was looking forward to getting jb but this is ridiculous. I finally get it and it thwarts my tethering. PDAnet does not work with most jb devices and that is the case for the Reverb with jb. I am told if I was root that I could use another app which would effectively disable Sprints internal blocking. So that everybody knows, the BIN4RY method DOES NOT WORK. Waste of time. It goes through the process and reboots this device, but when you try to confirm with Root Checker there is no root. Any ideas? Anybody?
