How to disassemble Realme XT, Step 1/1

Step 2. Remove the tray

Use the Key tool (aka Needle) or Paperclip. Push the tip all the way into the hole until the tray ejects, and then pull the tray 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.

Step 3. Open the back cover

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.

ℹ️️ 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.

Do not let the liquid get inside the smartphone. The process can be seen in our video entirely so as well as in detail, at the end of the instructions.

⚠️ Look in advance at the picture of the places where the touchscreen and display cables pass under the display module to avoid accidental damage.

Step 4. Unscrew the screws

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 20 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.

Step 5. Open the middle frame

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

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

⚠️ Be careful when opening the middle frame 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 middle frame to not damage them accidentally.

ℹ️️ The Realme XT (RMX1921) model has a battery BLP741 with 4000 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.

Carefully, preferably from the edge, disconnect the connectors and remove the inter-board cables connecting the mainboard to the daughterboard (also known as the sub-board).

⚠️ Be careful when removing the cables from the connectors, the cables are pretty thin, and it is easy enough to break them or damage the contact tracks inside.

ℹ️️ An arrow on the FFC cable (flexible flat cable) indicates its correct position.

ℹ️️ The board contains a headphone jack, microphone, 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.
