Happening periodically, sometimes shuts the module off, sometimes not. I'm sure factory reset/ firmware update are my only options. Hate to lose my settings. Anyway, other than brick by brick, to restore?
Can you please confirm the specs of the power supply you're using with your DM6? If you're in the US, you should be using a 9V DC 500mA pin-positive power supply.
If you're using the correct power supply with your module and are still experiencing this issue, you may need to service your product. Warranty and non-warranty claims are not handled here on the forum, but I can point you in the right direction! Here are a couple of options that you could choose from:
