Step 2. Open 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.
Step 3. Remove the battery
Carefully remove the battery.
ℹ️️ The Samsung Galaxy S5 mini SM-G800 model has a battery EB-BG800CBE with 2100 mAh capacity (aka rechargeable battery).
Step 4. Unscrew one screw
Using a screwdriver (Phillips 1.5 mm PH000), unscrew one screw and remove the cover hiding the connector.
Step 6. Open the display module
⚠️ Pay attention! Disassembly has a maximum 3rd difficulty because the process begins with the disassembly of the display module. If you have no experience or are not sure of your skills, we strongly recommend that you contact a specialized service center.
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 display module 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.
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 12. Remove the daughterboard
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, 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.
Step 14. Remove 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.
Step 15. In the housing remained
ℹ️️ In the housing remained: the earpiece speaker, loudspeaker, headphone jack socket, vibration motor.
