i was reading another topic then saw the 631 thing...so i made one i copied to my garmin device. lols
Right now, it boots straight up into normal mode ( No map)...wont be recognized by Garmin express ( on Mac/ or Windows- i also check the cable with my other nuvi 50LM- works).
i tried multiple, can not access the Pre-boot mode any more ( it was easy for me to enter pre-boot mode and flash the cure/ original firmware)...
device just go straight up into loading map/ calibration...Iam losing hope now.
i just cleared nonvol as well, no help.
