Now that we’ve got that the antenna cover off we’re gonna take that aluminum case backing off. This part is the hardest part! Again if you have a case cracking tool, use it. Be very careful since the silver bezel is right next to that curved aluminum back cover.Run the tool along the bottom edge of the aluminum backing on both sides of the phone. When you are able to crack it open enough, you’ll be able to pull it apart. See pics below.
