Be very careful during this step. You could hurt yourself on broken glass. Use gloves or cover the display with tape.

1. Put the suction cup as far down on the display as possible, for example where it says “Huawei.” If the glass is too cracked for the suction cup to generate a vacuum, you can cover the display with tape.
2. Pull on the suction cup while using the pick to push the back cover against the table. As soon as a gap appears between the display and the enclosure, you can carefully insert the pick.
3. Also move the pick along the edges to disconnect the display on the sides. Continue to pull carefully on the suction cup.

The fingerprint sensor is installed in the back cover. A flexible flat cable connects this sensor to the motherboard. Be careful when you take off the display to avoid damaging the cable or board.

4. Carefully lift the display. Slowly open the device at the short upper edge like a book. Now you should be able to see the connection cable.
5. Disconnect the cable from the motherboard by carefully inserting the spudger below the contact and disconnecting it.

1. Remove the two screws that hold the black plate in place.

2. Disconnect the plate from the motherboard. The plate is hooked on in three places. Insert the tweezers below the plate and carefully unhook it.
3. Disconnect the battery contact from the motherboard. Carefully insert the spudger below the contact and disconnect it from the socket.

1. Carefully detach the headphone jack’s plug connector using the spudger.
2. Then remove the jack from the enclosure.

3. Remove the rear-facing camera.

1. Disconnect the plug contact for the control buttons from the motherboard.
2. The control buttons are glued to the display frame on the side. Insert the steel laboratory spatula between the frame and the cable to detach the glue. Start with the individual button. The cable’s very delicate.
3. Then disconnect the other two buttons from the frame.
4. Remove the cable.

1. First disconnect the display connection from the motherboard. Insert the spudger below the contact and disconnect it.
2. Disconnect the connection cable for the lower board.
3. Disconnect the coaxial antenna cable from the board. Don’t pull on the cable because you could break off the connector.

1. Four screws hold the motherboard in the enclosure. Remove the screws.

2. There are also hooks holding the board in place. Carefully detach the board on the right side by using the spudger as a lever.
3. Repeat this step on the left side.
4. Remove the board.

1. Use the spudger to disconnect the speaker contact from the lower board. Insert the spudger below the contact and carefully disconnect it from the socket.
2. Remove the connection cable for the motherboard.
3. Carefully disconnect the coaxial antenna cable. Don’t pull on the cable because you could break off the connector.

2. The board is also hooked onto the frame. Using the spudger, carefully detach the board from the fixture.
3. Remove the board.

1. There are two adhesive strips holding the battery in the enclosure. The ends of the adhesive strips are attached to the top (blue ends in the picture). Use the tweezers to detach them.
2. Once you’ve detached the ends, you can slowly and carefully pull on them at a straight angle and steady speed. Pull out one strip after the other. Don’t worry if one of the strips tears and you can’t remove it all the way.
3. Use the spudger to detach the battery from the enclosure and then remove the battery. Insert the flat, blunt end of the spudger below the battery and lift it.

1. Using the steel spatula, detach the earpiece from the enclosure. Put the spatula on the right side and pry out the earpiece.

1. The vibrator motor is glued to the enclosure. Using the steel laboratory spatula, carefully detach the motor. Carefully insert the spatula below the contacts and detach the glue.

1. Remove the two screws that attach the speaker to the enclosure.

2. The speaker is also lightly glued in place. Detach the speaker by inserting the spudger below it and lifting it up.
3. Remove the speaker.

1. You have to stick the display cable to the frame. There’s still red protective film (arrows) on the adhesive surfaces.
2. Uncover the adhesive surfaces.
3. Stick the display cable in place. Make sure the entire cable is lying flat.

1. Remove the red protective film to expose the adhesive surface.
2. Then put the speaker back on. Make sure it’s positioned correctly. Put the speaker at the middle strip first and then tilt the speaker downward.
3. Press it on firmly with your fingers so the glue will stick better.
4. Then fasten the speaker with the two screws.

1. Remove the red protective film to expose the adhesive surface.
2. Then put the vibrator motor back in. Make sure you guide the two holes in the cable onto the two tabs in the frame. Gently press the motor onto the glue.

1. Remove the red protective film covering the adhesive ring.
2. Put the earpiece back in and press it gently against the adhesive ring.

In this guide, we use adhesive strips from the iPhone 6. No original adhesive strips were available when we took the pictures.

1. Before you can install your new battery, you have to attach the adhesive strips. Turn the battery so you can see the back of it. The adhesive strips keep the battery from rattling around in your device. Attach the adhesive strips so the ends stick out past the battery on the side with the display contact. This is important because you have to be able to stick the ends to the top of the battery in the next step.
2. Turn the battery around and remove the protective film from the ends of the adhesive strips. VStick them to the top of the battery. This way, you can easily remove the battery if you need to repair your phone again.
3. Turn the battery back around and remove the protective film from the adhesive strips. The battery is now ready for you to install.

Before you can install your battery, you have to attach new adhesive strips to it.

1. Put the battery in the compartment in the enclosure. Push it in all the way to the right. Make sure it’s aligned properly. The battery contact has to be aligned with the display contact.
2. Then press on the battery firmly with your fingers so the glue will stick better.

1. Put the board with the USB port back in. Make sure the board’s aligned right and that the speaker’s contact doesn’t get stuck under the board.
2. Press on the board so it clicks into the frame, and then secure it with the two screws.
