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

Using a spudger or a plastic pick, carefully, around the edge, detach the back cover clips, and remove it.

Do not insert the tool deeply or bend it. Otherwise, the housing may be tampered with or damaged.

Carefully remove the battery.

ℹ️️ The Prestigio Muze D3 PSP 3530 Duo model has a battery PSP3530 Duo with 2500 mAh capacity (aka rechargeable battery).

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 13 short screws and three long black screws.

ℹ️️ Be sure to note the location of the screws before disassembling. When assembling the device, screwing the screw in the wrong place may damage the device or its part. To avoid damage, the removed screws and individual pieces (as gaskets or brackets) must be laid out in the appropriate order, or the screws and their holes in the phone must be marked with colored markers.

Remove the cover with antennas that protect the printed circuit board (PCB). Try to lift the covers by the edges and not push anything between them to not accidentally touch or short-circuit anything on the PCB.

ℹ️️ On the upper cover, you can see the metalized coating on the plastic in the form of tracks and contact pads. These are Wi-Fi, Bluetooth, and GPS antennas.

Disconnect the coaxial cable connector, cable to the touchscreen, on the daughterboard.

⚠️ Do not pull on the cable or pry it with a sharp tool, the connectors are pretty weak and break easily, or the cable falls out of the end (lug).

Remove the sub-board. It is glued to the frame with metalized tape, so to facilitate the process, the board can be heated a bit. Also, remove the vibration motor and loudspeaker both wired with the sub-board.

⚠️ It is not necessary to insert the tool under the board when removing the sub-board. Internal components could be damaged.

Pry up the display module connector. Also, unstick and bend the buttons cable up.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew one screw.

Carefully remove the printed circuit board. There is no need to use a lever or try to reach the board by force. Make sure that nothing is getting in the way or holding the board.

⚠️ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.

ℹ️️ In the display frame remains the earpiece speaker.
