I have a brand new device with a DNA250C board that will not charge internally. While I know it's better to charge externally, I am worried this may be indicative of a board issue, as I've also had a few issues with the ohms jumping from time to time. Occasionally it will begin to charge, but then cut off. This happens whether I am charging with my computer or through a plug in the wall, etc. I've both restored the device to defaults (to no avail), and performed USB Battery Recovery, but with no luck. Any help to enable charging on the device would be appreciated. Cheers!
