How to Install Latest OTA and Stock Firmware on OnePlus 3T

From the design standpoint, the OnePlus 3T looks exactly the same as the original OnePlus 3. It’s a full metal unibody design with a slightly curved backside rounded corners, and because of the back tapers along the edges, it allows the phone to feel a lot thinner. Despite being made almost entirely of metal it’s surprisingly lightweight making the phone feel very comfortable to hold, it’s also not a very wide or tall phone, so it’s pretty manageable to use in one hand even with this fairly large 5.5-inch screen.
