If you can't reset it through the regular phone settings in the phone's menu, you'll need to go through the recovery menu. Do a Google search for accessing the recovery menu for your phone.... it's a very easy process.
I have The Moto G Stylus. I did a reset through the recovery menu and now when I plug my phone into the computer. It sees it as Motorola XT 1097 .. What gives ??
Welcome to Android Central! The model number in Settings>About Phone is still XT2043, right? It probably has more to do with the PC's drivers rather than the phone.
