"-Baseband Version VS740MVB.5210.1015: (new radio.img) Flash this just like a kernel. You must reboot into recovery once more after installing to wipe your cache. *Only flash once! I cannot be held liable for any damage caused to your device by flashing this!" If you back rev to Velocity 0.2 from Velocity 0.3, do you need to redo the Baseband update, or is it permanent?
