Disassembly/Repair of the mobile device Samsung Galaxy Watch 6 SM-R930 with each step description and the required set of tools.

⚠️ Before disassembling, do not forget to turn your phone off.

So, after heating, we need to unscrew the four screws that secure the back cover. For this, we’re using a 2mm Tri-Wing screwdriver.

⚠️ Please note that this is not a typical Tri-Wing screwdriver. It’s a special one designed for Samsung watches. If you try to use a regular Tri-Wing screwdriver, you might damage the screw threads.

After that, we need to separate the back cover.

The back cover is firmly glued on. For this, we can use a thin plastic tool or a thin plastic film. Carefully insert it into the gap between the case and the back cover, and gently slide it along to cut through the adhesive.

⚠️ It’s quite challenging to insert the thin plastic film because, as I mentioned, the cover is firmly glued.

This film can be from a new display protector or a film from a stationery store.

⚠️ Be careful not to insert the tool too deeply to avoid accidentally damaging the cable that runs from the back cover to the motherboard.

Then, we use a non-metallic tool to disconnect the sensor connector and remove the back cover

Using a screwdriver Phillips 1.5 mm (PH #000), unscrew the two screws and remove the bracket holding the speaker.

Carefully remove the speaker.

We disconnect the side button connector, and disconnect the display cable connector with a non metallic tool.

And after that, we need to unscrew one screw that secures the motherboard to the frame (bracket).

For this, we’re using a 1.5mm Phillips screwdriver or a #000 Phillips screwdriver.

Now, we can carefully remove the motherboard — take it out and set it aside.

We can also remove the frame (bracket).

Gently lift and remove the frame.

Inside the frame, we have the battery.
