Introduction
What you need
Step 1
Back Cover
- Power down the phone.
- There is a screw located inside the 3.5mm headphone jack that needs to be loosened. Use a Torx T5 screwdriver for this.
- The screw does not come out. Once loosened, It will unlock the lock bar inside the phone. You will break it if you do not complete this step properly.
- Remove the sim card tray on the top of the phone.
- Remove the 4.5 mm Torx T5 screw highlighted with a red circle in the picture. (Note: all screws that you will remove in the phone will be the same)
- There is a sticker located on the screw that needs to be peeled off. This voids your warranty.

- It can be useful to flip the plastic opening tool upside down in certain areas of the phone to make releasing the plastic clips easier.
- Once all the clips are released, remove the back cover of the phone.

Be carefule in step 4, the red circled connector’s other side is attached by a pair of small plastic hooks to the motherboard. One of the hooks is very small and can be easily bent if that side comes off and has to be reattached.
