Disassembly steps

For disassembling you need the Nokia Standard toolkit version 2. You will also need the camera removal tool SS-210. If the device is brought to service due to problems with NFC or wireless charging, please collect the BATTERY COVER as well.

Before starting the disassembly, make sure that the device is powered off. Protect the TOUCH WINDOW with protective film.

Start releasing the BATTERY COVER by pushing down the top right corner.

Then release the top left corner so that the main body comes out of the BATTERY COVER ASSEMBLY.

Lift up the main body from the bottom end.

The BATTERY COVER can now be separated from the main body.

Unscrew the three TORX+ size 4 screws in the order shown. Do not use them again. Discard them.

Unscrew the four TORX+ size 4 screws in the order shown.

Lift up and remove the CHASSIS ASSEMBLY.

Remove the CAMERA by using the camera removal tool SS-210. First place the SS-210 on top of the CAMERA. Press down carefully the black plastic parts of the SS-210. And then press down the metal sheets until the camera retaining clips are released.

Grab the sides of the SS-210 and lift up to remove the CAMERA.

Open the TOUCH CONNECTOR with the SS-93. Be careful not to damage the connector or any nearby components.
