Disassembly/Repair of the mobile device Lenovo Vibe P1 (Lenovo Vibe P1 P1c58) with each step description and the required set of tools.

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

Open the cover hiding the screws securing the back cover.

Pull the tray of SIM and Memory card (Micro SD) out.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew the three screws securing the back cover.

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.

⚠️ Be careful when opening the cover from the volume and power buttons side. Thin cable and fragile buttons are straightforward to damage.

⚠️ Look in advance in the picture for the cables’ location for inter-board, touchscreen, display, buttons (if any) under the cover to not damage them accidentally.

Remove the cover with antennas. 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.

⚠️ It is crucial while reassembling, checking the spring contacts on the board, and the contact pads on the cover match and touch. Otherwise, signal loss or signal may be quite weak.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew the three screws securing the motherboard.

Turn the upper board with card holders and flash out. Disconnect the connector and remove the board.

ℹ️️ The Lenovo Vibe P1 (P1c58) model has a battery BL244 with 5000 mAh capacity (aka rechargeable battery).

⚠️ It is highly recommended to disconnect the connector to avoid possible short circuits during disassembly. Also, try not to use a metal tool to disconnect the rechargeable battery connector or do it carefully.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew the six 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 parts. 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 loudspeaker assembly with antennas.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew two screws securing the daughterboard.

Disconnect the coaxial cable connector, cables to the mainboard, and inter-board sub-screen cable 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.

ℹ️️ The board contains a charging port (Micro USB), microphone, vibration motor, spring contacts for the speaker, and an antenna unit.

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