If you could make a backup of the internal files system then YOUR device didn't need a cure firmware because it could still be seen in MSM. So why flash Cure3?
Please explain EXACTLY what the problem is. We have experts posting in this thread presently, and there's not many ppl who understand the peculiarities of both the hardware and software of the Kenwood-Garmin marriage. However there's even fewer ppl in the world with psychic powers [Caty does go close though].
