Nokia N900 Slider Assembly Replacement

Turn the phone over so the screen is face down.

Remove the back cover by locating the slit on the bottom of the phone and lifting up.

Remove the battery by lifting it out of the device.

Remove the two "L-shaped" antennas by unscrewing the following screws:

Four screw M1 .4x5.0

Two screw RF1 .4x4

In addition to unscrewing the screws, remove the B-Cover (which will fall right out without the screws).

Turn the back of the phone over so the keyboard is face up. You should then have two halves of the phone.

To locate the slider, find the "black tape" on the screen half of the phone.

Weave the "slider tape" through the orange slot on the keyboard half of the phone.

Once you have completed these steps your phone should be able to slide up and down with ease.
