⚠️ Before disassembling, do not forget to turn your phone off.
Disassembly of the mobile device HTC U11 Plus (HTC U11 Plus (2Q4D100)) 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.
⚠️ 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.
⚠️ Pay attention to the fingerprint sensor cable located from the inside of the back cover.
Step 4. Disconnect the fingerprint sensor
Pry up the fingerprint sensor connector and remove the back cover.
Step 6. Open the cover
Remove the cover with antennas and an NFC tag that protect the printed circuit board (PCB). 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.
Step 7. Disconnect the battery connector
Disconnect the battery connector as soon as possible.
ℹ️️ HTC U11 Plus (2Q4D100) model has a battery G011B-B with 3930 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 10. Disconnect the connectors
Disconnect the coaxial cable connector, cables to the mainboard, charging port, 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).
Step 11. 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 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.
Step 15. Disconnect the connectors
Pry up the connectors of power volume buttons cable, display module cable, earpiece speaker cable, inter-board cables, and coaxial cables.
⚠️ 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 16. 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.
