⚠️ Before disassembling, do not forget to turn your phone off.
Disassembly of the mobile device Samsung Galaxy Tab S5e SM-T720 with each step description and the required set of tools.
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 of SIM and Memory card (Micro SD) out.
ℹ️️ Remember the location for the SIM and Memory card (Micro SD) trays so that nothing is confused when reassembling.
⚠️ 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 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.
⚠️ It is important not to get a film between the touchscreen/glass and the display module. This will damage the module.
⚠️ 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 5. Unscrew the screws
Using a screwdriver (Phillips 1.5 mm PH000), unscrew 36 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 8. Remove the inter-board cable
Carefully, preferably from the edge, disconnect the connectors and remove the display module cable.
⚠️ 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.
Step 10. Disconnect the battery connector
Disconnect the connectors on the small board.
Disconnect the battery connector as soon as possible.
ℹ️️ The Samsung Galaxy Tab S5e SM-T720 model has a battery EB-BT725ABU with 7040 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.
Step 12. Remove the small board
Remove the small board.
⚠️ It is not necessary to insert the tool under the board when removing the sub-board. Internal components could be damaged.
Step 15. Remove the cameras
Disconnect the connectors and remove the front (selfie) and rear cameras.
Step 17. Unscrew one screw
Using a screwdriver (Phillips 1.5 mm PH000), unscrew one screw securing the PCB.
Step 18. Remove the PCB
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.
