Hello, just received a Redmi Note 3G from b2cbuying.com. It came with a non-standard V96 something multilang firmware (not upgradeable). For some reason, there is no updater app. Additionally, trying to select manually a firmware from about phone, crashes to the home screen... Upon further inspection, the phone had a serial number 01234567890abcdef! Obviously, this had nothing to do with the number on the box. Any idea what might be happening here? Perhaps a refurbished unit?
