Hello friends, After i upgraded my dna200 to v 1.2 sp3 the battery level from 3% went down to 0%. I tried to reset it but still the same. I also tried the usb recovery option which turned it to 1% but then it went back to 0. Any ideas or help? PS the cell 2 and 3 are at 3.77v while the cell 1 is at 3.33
