I had an original design refresh that was having volume button issues with, and a broken speaker. Anyway, a few days before getting my replacement device under warranty I get the 6.0.1 update. I upgraded without issue on my original device. I get my replacement device a few days later, and now it says, that it is update to with version Marshmallow 6.0. I have factory wiped the device from the bootloader and from within the OS at least 5+ times. I wiped a twice before my trip, twice while on my trip, and once since I have been back home. I have even contacted Verizon support via Twitter. They suggested that I wipe it. Which I did. I have even wiped and restored without restoring my apps or data. Does anyone else have any ideas? Sreenshot below for proof.
