Insert a SIM card removal tool into the small hole on the top right corner of the phone, above the volume buttons. If you do not have the original packaging or a SIM card removal tool, use a straightened paperclip. Push the tool into the hole. The tray should pop out.

There is absolutely no reason to remove the sim tray, we're not removing the motherboard.

Put on heat-resistant gloves and place the phone on a surface that will not catch fire or melt. Using a heat gun, slowly and evenly heat the edges of the rear panel. Do not linger too long on one spot. The heat gun can damage the device if left on one section for a long period of time.

  • While heating the rear panel, use a Jimmy to test if the adhesive is soft enough to allow the panel to separate from the device.

  • Carefully detach the rear panel, using opening picks to hold the panel apart from the device.

  • Once most of the edges are separated from the device, attach a suction cup to the panel.

Press the suction cup to the rear panel to secure it. With the help of the suction cup, pull up on the panel to completely detach it from the device. Use the suction cup to safely remove the panel from the device. As you work around the panel's edges, the lingering heat may cause the remaining adhesive to reattach the panel to the device.

It can't be stressed enough to do this very carefully. I did it very carefully, but not carefully enough. Cracked a corner. Also not just the edges, there's extra adhesive on the lower 2-3 cm's of the back.

Another remark, get in between the black bezel and the back cover, this is a bit unclear on the first picture. Same goes for the front, get in between the bezel and the front assembly.

Using a PH000 screwdriver, remove the following seven screws: Four (longer) Phillips 000 screws Three shorter Phillips 000 screws
  • Using a PH000 screwdriver, remove the following seven screws:

    • Four (longer) Phillips 000 screws

    • Three shorter Phillips 000 screws

  • Once all of the screws are removed, proceed to using a plastic spudger to pry the metal cover off.

  • There are two clips near the bottom, right above that battery, so start by prying on the bottom edge of the plate.

What size of screw goes where?

Once the metal cover is removed, locate the battery connector wire, which clips into the motherboard. Using a plastic spudger, gently pry on the clip to release it.

On the battery, locate a clear tab. This will be used to pull the battery out. Firmly grasp the clear tab and pull up and away from the phone. Take your time on this, as you do not want to apply to much force and damage the battery.

  • There is an adhesive underneath the battery so it might be useful to utilize the black plastic spudger to get between the battery and the phone to remove the adhesive.

  • Continue to pull the battery until it is completely free from the phone.

Strictly speaking, you don't need to remove the battery at all. The connector to the front assembly is underneath the speaker assembly.

Using a PH000 screwdriver, remove the 8 screws from the logic board, circled in the diagram. We removed the screws when we removed the screws for the top metal cover. As long as the screws have been removed prior to removing any cables or wires, the order in which you remove the screws does not matter.

With the battery removed and the metal covers off, disassembly can continue. Using the plastic spudger, locate the rear-facing camera and unclip it. Once unclipped, set the camera aside. Using the metal spudger, pull off the wire connector, circled in the diagram, and push it away.

Switch back to the plastic spudger and start to pry at the upper logic board. Carefully pry it up until you can safely remove completely. Be careful when pulling up the upper logic board, the front camera is clipped underneath and pulling too hard may damage it. On the bottom left hand side of the phone, you will see a small screw. Use PH000 Philips head screw driver to remove the screw.

After removing the Philips head screw,  you will need to remove a black wire. Use a metal spudger to unclip the cable. It might be helpful to bend the cable out of the way when working on the phone. Pull back on the ribbon-like cable shown in the image. This is connected to both the charging port and the vibration module (which is similar to a small watch battery).

  • You will need to remove the vibration module before the charging port.

Once the vibration module is out, pull up carefully on the cable as the charging port is attached with adhesive. After carefully pulling the port and vibration module, it should now be free from the phone and can be replaced.

So how do you replace the part with a new one? Says in the top description "no parts required"

robin - Reply

I had to reuse the vibration motor de- and solder it back on, because it is not included in the spare part.

Watch for the silence switch when you reasamble the phone. I had to unscrew the upper bord again because i didn't payed atention to it and it was locked. Also the mic is covered on the replacement part. Don't forget to remove the yellow "flag" there.
