⚠️️ Before disassembling, do not forget to turn your phone off.
Disassembly of the mobile device uleFone Power 6 with each step description and the required set of tools.
Step 2. Remove the tray
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.
Step 3. Unscrew the screws
Using a screwdriver (precision star-shaped 0.8 mm aka Pentalobe), unscrew/drive 2 screws out at the end of the phone.
Step 4. 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.
⚠️️ Be careful when opening the cover from the volume and power buttons side. Thin cable and fragile buttons are straightforward to damage.
⚠️️ Pay attention to the fingerprint sensor cable located on the inside.
Step 6. Open the cover
Carefully remove the cover hiding the motherboard.
⚠️️There is one thing we must keep in mind. We have to be careful! Two cables pass through the small windows (holes) of the cover. Two cables of different lengths are attached in different places with two different connection types.
The black one, which is glued to the cover from the inside, has a contact pad for spring contacts. Moreover, the cable is short and goes under the battery, so you need to understand how we lift and in which direction we rotate the cover.
Copper one is a fingerprint sensor cable connected to the motherboard with a connector. It is much longer than the black one.
Also, we should not use a metal tool to avoid short circuits because the battery is still powered.
Step 7. Disconnect the battery connector
Disconnect the battery connector as soon as possible. It is better to use a non-metal or plastic tool to avoid any damage.
ℹ️️ The Ulefone Power 6 model has a battery 3081 with 6350 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. Unscrew one screw
Using a screwdriver (Phillips 1.5 mm PH000), unscrew one screw securing the sub-board.
Step 11. Disconnect the connectors
Disconnect the coaxial cable connector, cable to the mainboard, 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 12. Remove the daughterboard
Remove the sub-board. It may be glued to the frame with metalized tape, so to facilitate the process, the sub-board can be heated a bit.
The sub-board, also, may be attached with attachments like latches or hooks. Be careful.
ℹ️️ The sub-board contains a charging port (Micro-USB), microphone, vibration motor, spring contacts for the speaker, and an antenna unit.
⚠️️ It is not necessary to insert the tool underneath when removing the sub-board. Internal components could be damaged.
Step 13. Disconnect the connectors
Pry up the connectors of power volume buttons cable, display module cable, and coaxial 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 15. Remove the cameras
Pry up the connectors, remove one rear camera and one front (selfie) camera.
Step 16. Remove the motherboard
First of all, we have the earpiece speaker wired, so we have to decide, wether we unsolder the wires or unstick the speaker glued with adhesive to the display frame. In our case, we unstick the earpiece speaker.
Remove the proximity sensor from the indentation in the display module frame.
After, we lift the motherboard and rotate it to the vertical position. We can't remove the motherboard yet, we still have two cables connected from the inside to disconnect.
When we disconnect the two connectors, we are ready to remove the motherboard.
