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 for SIM cards out.
â ī¸ī¸ 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.
âšī¸ī¸ 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 the 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.
Step 4. Unscrew the screws
We move on to unscrewing the screws at the top, we use a Phillips 1.5mm or #000 screwdriver.
The screws can be different so we need to be careful and the screws are badly magnetic and hard to pull out, so we will need tweezers to get them out.
Please note that there are several screws under the side gasket. We need to peel back this gasket and unscrew them all.
Step 5. Open the cover
Pry over the edges. Move an opening tool along the edge detach the clips and remove the cover with transmission lines and pads for antenna.
âšī¸ī¸ Try to lift the cover by the edges and not push anything between them to not accidentally touch or short-circuit anything on the circuit board.
Step 6. Disconnect the battery connector
Disconnect the two battery connectors as soon as possible. It is better to use a non-metal or plastic tool to avoid any damage.
âšī¸ī¸ The HONOR 70 FNE-NX9 model has a battery HB506390EFW with 4800 mAh capacity (aka rechargeable battery).
Step 9. Disconnect the connectors
Disconnect the two connectors of the two coaxial cables, the inter-board cable connector and the fingerprint sensor connector. We also need to release the cables from the clamps securing them to the sub-board.
Step 10. Remove the daughterboard
Remove the sub-board. It may be glued to the frame or attached with attachments like latches or hooks, so be careful.
âšī¸ī¸ The sub-board contains a charging port (Micro-USB), microphone, spring contacts for the speaker, vibration motor, and an antenna unit.
â ī¸ī¸ It is not necessary to insert the tool underneath when removing the sub-board. Internal components could be damaged.
Step 11. Remove the cameras
Pry over the edge and detach the assembly of the two rear cameras and one rear camera.
Step 13. Disconnect the connectors
Disconnect the display cable connector, the inter-board cable connector, two connectors of the two coaxial cables.
Step 14. Unscrew the screws
Using a Philips 1.5 mm screwdriver (PH#000), unscrew the two screws.
If the screws are different: âšī¸ī¸ 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 parts. 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 15. Remove the motherboard
Carefully remove the printed circuit board. There is no need to use a lever or try to reach the circuit board by force. Make sure that nothing is getting in the way or holding the circuit board.
The motherboard, also, may be attached with attachments like latches or hooks, be careful.
â ī¸ī¸ 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 16. In the display frame remained
âšī¸ī¸ In the display frame remained: the earpiece speaker, battery, fingerprint sensor, vibration motor, and two coaxial cables.
