Replace your nifty Kevlar-clad back cover that you recently discovered isn't actually bulletproof.
Insert a plastic opening tool between the back cover and rear case at the lower left edge of the back cover.
Pry the back cover up with the plastic opening tool to free the plastic clips.
Continue prying along the left edge of the back cover towards the top of the phone.
Work the plastic opening tool across the top of the back case to free the plastic clips.
Continue prying down the right side of the back cover to free the remaining clips.
Pull the back cover away from the phone to remove it.
