have you tried using white rabbit nv items on the echo? we need to be carefull writing motorola nv items to phones other than motorolas,just for the simple fact that the same things are not stored in the same address's when you jump from manufacturer to manufacturer.so if there is something else important is written to an address you change w/white rabbit nv's whatever that is,is gonna stop working.so at least be smart and backup nv's before trying w.r. on phones other than moto.
