Einleitung

Ensure to have a new/flawless motherboard lying next to you before you start removing the defective one.

You should also have a little bowl ready to set aside screws and other small parts.

Werkzeuge

Schritt 1

Before you start disassembling your device make sure that it is turned off.
Put on the Anti-Static Wrist Strap and clamp the end of the band to an unpaintet spot of a radiator.

Schritt 3

Remove the battery.
The battery lid is designed to function as an instrument for this task.

Schritt 4

Unscrew the six Torx #4 (5,3 mm) screws from both sides of the device
Collect the removed screws in a bowl or something comparable, otherwise they might get lost.

Schritt 5

Remove the upper ornamental part from the housing.
If your fingernails are not long enough you can use a plastic opening tool.
When reassembling the device be aware that the six shackles on the sides of the upper ornamental part need to be placed inside the frame.

Be carefull, the newer versions of the unit have the display “glued” to front cover to stop dust getting between the outer cover and display. The display now comes out with front cover and as such care must be taken with cables

Schritt 6

Lift up the housing.
The display as well as the speaker are connected to the motherboard. Therefore you need to be careful not to harm those connections.

Schritt 7

Unlock the connection between display and motherboard by pushing open the brown cleat.
It is recommended to use a spudger or a comparable tool for this step.
If the connection is not completely open, one of the involved components could easily be harmed.

Schritt 8

Separate the connection by pulling out the display cable.
If the cable does not come out easily, the connection is probably still locked.
When reconnecting the display to the motherboard don't forget to lock the connection, otherwise it will eventually come loose and you will have to redo the first eight steps of this guide.

Schritt 9

Remove the mounting spring from the speaker with a pair of tweezers.
If you just want to replace the motherboard, it is recommended to ignore the steps 9 and 10.

Schritt 10

Take off the safety mat from the speaker.
Remove the speaker from the housing.

Schritt 11

Unscrew the eight Torx #4 (5,0 mm) screws from the motherboard.
These two screws connect the motherboard with the sliding cage. In this guide they are removed as well. Hence this is not compulsory you can decide for yourself whether you want to remove them now or later.

Schritt 12

Push in the SD-Card to eject it.
If the memory card remains in its slot you will not be able to remove the motherboard.

Schritt 13

Abstract the motherboard.
Lift up the motherboard as shown in the picture before completely removing it.
When inserting the motherboard first put in the side with the speaker jack on it and make sure that the microphone is placed properly under the motherboard.

Abschluss

Dissolve the solder connections between motherboard and speaker (step 14) as well as the microphone (step 14). Then solder both components to the new board.

Replace the old motherboard by a new one and then reassemble your device. Therefor follow these instructions in reverse order.
