Tutorial: Step by step

Step 1 belt

First we must unhook the strap.

Step 2 screen

We apply heat to the screen with a hot air gun, and with the help of a fine tine we will make a hole to introduce a plastic spike so as not to scratch the screen. With the help of flat tweezers we will remove the adhesive that is on top of the connectors, and with a flat tool we will disconnect them. Remove the Triwing screws (Y0.6), and disconnect the connect the force touch sensor that is attached to the screen.

Step 3 Drums

We remove the Triwing screw (Y0.6) that is in the corner of the smartwatch, take off the battery, and underneath we will have to remove another Triwing screws as the previous one, to be able to extract the shielding and thus disconnect the battery.

Step 4 Vibrator

We extract the three Triwing screws (Y0.6), disconnect the vibrator connector, and with flat tweezers we can remove the vibrator.

Step 5 Speaker

We remove the three Triwing screws (Y0.6) that hold the loudspeaker, and with the help of flat tongs we will take it off.

Step 6 Screws

We extract the five Triwing screws (Y0.6) that we pointed out in the first two photos of this step.

Step 7 Flex with pushbutton and key

Disconnect the connectors, remove the three Triwing screws (Y0.6) and the shields, and the side key will almost fall off by itself, and with a flat clamp we will take off the flex.

Step 8 Motherboard

Remove the four Triwing screws (Y0.6) that hold the base plate, and with the help of flat clamps we have removed the base plate.
