Disassembly/Repair of the mobile device vivo V20 SE with each step description and the required set of tools.

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

Use the ejection tool (aka Needle) or Paperclip. Push the tip all the way into the hole until the tray ejects, and then pull the tray of SIM and Memory card (Micro SD) out.

⚠ Pay attention! The tool must be inserted into a hole on the edge of the phone's housing. Do not press too hard. It may break the tray eject mechanism.

We recommend using a special heating device such as a separator machine, heat gun, or heating mat. It will simplify the process. You can use a home hairdryer, but you will have to make a nozzle by hand or have a suitable one in the kit to gently heat and concentrate the heat flow in the right place.

ℹ️ The surface of the back cover must be heated to soften the adhesive underneath. The approximate heating temperature is 50° C / 125° F.

Use a thin plastic film or pick for separation. To facilitate the process, you can use isopropyl alcohol. It is often most difficult to pass the tool between the parts to be divided. Choose the far edge from the FFC cables or buttons.

Do not use a lever or any force for separation that could damage the elements inside.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 16 screws.

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

ℹ️ 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.

Remove the cover with contact pads for antennas and an earpiece speaker.

Disconnect the battery connector as soon as possible.

ℹ️ The vivo V20 SE model has a battery B-O6 with 4100 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.

Remove the loudspeaker assembly with antennas.

Carefully pull the tag up to unstick the battery from the display frame.

Pry up all connectors on both boards. After that, we need to peel the protective film to the opposite side to open some space for cables removal.

Also, we need to unstick the black thing like a gasket. So, when we have enough space, we peel back the inter-board flexible flat cable and pry to remove the sub-board.

Honestly, we can not remove the sub-board yet, just unfasten it and turn it over. 

Disconnect the coaxial cable and now we can remove the sub-board.

ℹ️ The sub-board contains a charging port (Micro USB), microphone, headphone jack socket, spring contacts for the speaker, and an antenna unit.

Disconnect connectors for a display module, coaxial cable, all cameras, and remove three rear cameras and one front (selfie) camera.

Using a screwdriver Philips 2.5 mm iPhone with a tiny tip at the end, we call it a barrel screwdriver because the screw looks like a barrel. Unscrew one barrel screw.

It's totally unusual to see barrel screws in vivo because Apple created and used barrel screws for iPhones for a long time alone. Anyway, it is a smart solution to save one screw holding the motherboard.

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.

ℹ️ In the display frame remained: the earpiece speaker, coaxial cable.
