the 5.30 update for the handheld (dakota 20). also caused numerous issues. it began to boot, then would just power off. I assumed the batteries were dead….. so right before my trip, I popped in a new set, same thing…… after several hours of research, I was able to start the device in mass storage mode and manually delete the update file, and manually install it. after several attempts, i was able to get it to start, but if I shut it down, i would have to pull a battery to get it to turn back on. now the maps no longer work…… I'm going to reformat memory card as step 1. and try and reinstall….. however the device still will no longer be recognized by the computer unless it is in mass storage mode.
Bottom line, DO NOT update your device firmware…. unless i seem to be an anomoly here. Has anyone been able to complete this update without issue? I found a host of the same complaints in numerous forums worldwide and hence have been able to get this far…. i'm hoping i can get this fixed for good soon. NOT what I wanted to do returning from my overnight…..
