Flip the phone back over. First, unlatch the charging port flap at the bottom of the device with your finger.

Press firmly on corners of the midframe while holding on to the plastic bezel (the outer plastic ring).

Hold the device in one hand. Then apply pressure with your fingers to the back of the frame at the top of where the battery was. Then remove the midframe by pulling it outwards and towards the top of the phone.

When putting the phone back together, insert the bottom first by inserting the charging port into the notch shaped for it. You must do this first or the midframe will not fit in the plastic bezel.
