Disassembly/Repair of the mobile device HONOR X7c (Honor X7c ALT-LX1) with each step description and the required set of tools.

⚠️️ Before disassembling, do not forget to turn your phone off.

First, we need to remove the SIM card tray.

To do this, use the SIM eject tool—insert it into the small hole and gently push to release the tray.

Next, we’ll need to heat up the back cover to about 60°C (or 140°F).

For this, we’re using a heating pad, but you can also use a heat gun or hairdryer if needed.

After heating the back for 5 to 7 minutes, we can start removing the back cover.

To do this, use a thin plastic film—something like a screen protector or even a piece of stationery film will work.

Insert it into the gap between the middle cover and the back cover, and carefully slide it along the edges to cut through the adhesive.

Make sure to be extra careful around the side buttons—there’s a fingerprint sensor flex cable in that area.

⚠️️ Also, be cautious around the camera module so you don’t damage the lenses.

Gently lift the back cover—note that there’s extra adhesive around the camera area.

With the lenses protected, we can move on to removing the ten screws.

To remove the screws, we’re using a 1.5 mm Phillips screwdriver (Phillips #000).

As we take the screws out, we’ll place them on a magnetic pad or designated surface, keeping them organized by location to make reassembly easier.

For extra clarity, it’s a good idea to separate the screws from the top and bottom sections.

Use a Phillips screwdriver (size 1.5 mm, PH #000) to remove the small silver screw located in the center.

To remove the seven screws at the bottom, we’re using a 1.5 mm Phillips screwdriver (Phillips #000).

Once all the screws are removed, we’ll move on to detaching the mid-frame.

Start by inserting a thin plastic film into the gap between the mid-frame and the display frame—begin near the SIM card tray area.

Release a few clips, then switch to a slightly thicker tool to continue separating the frame.

As always, be extra careful around the corners, as they tend to hold tightly.

Also, take care around the display edges to avoid any damage.

⚠️️ Note that this mid-frame is additionally glued along the edges, so take your time separating it to avoid damaging the fingerprint sensor flex cable underneath.

Once the mid-frame is loosened, carefully flip it over to access and disconnect the connectors.

Start by disconnecting the battery connector using a plastic (non-metal) tool.

ℹ️️ The Honor X7c ALT-LX1 model has a battery HB476594EGW with a capacity of 5100 mAh (also known as a rechargeable battery).

Then, unplug the fingerprint sensor connector located on the mid-frame and set the frame aside.

Next, we move on to the motherboard. First, carefully disconnect the front camera and peel off the thermal pad covering it.

It's also a good idea to cover the cameras lens with a protective film to avoid smudges or scratches.

Once it’s protected, set the front camera aside.

Do the same for rear cameras, and set those aside as well.

Next, we’ll remove the loudspeaker module at the bottom. Gently pry it up from one edge and lift it out.

At this point, we need to remove one small silver screw that secures the sub-board.

Again, use the 1.5 mm Phillips screwdriver.

We disconnect the interconnect flex cable, unplug the coaxial cable connector, and free the cable itself.

Then disconnect the second coaxial cable.

Carefully pry up the sub-board from the edge and remove it.

As we can see, the sub-board houses the charging port, microphone, headphone jack port, and other components on the reverse side.

Now we can start disconnecting the remaining connectors: detach the interconnect flex cable - the display cable, and the two coaxial cable connectors.

And we can remove the motherboard. Find a safe spot to gently pry it up from the edge, lift it, and remove it.

Keep in mind that thermal paste may be holding it slightly in place from the underside, which is normal.

Finally, we’ll remove the battery.

Fold back the brown pull tabs and check the printed instructions on the order in which to pull them. Following the guide, pull the center tab upward to safely detach the battery.

Underneath the battery, you’ll find a transparent adhesive layer that protects the interconnect flex cable.

ℹ️️ In the display frame remained: the earpiece speaker, vibration motor, and cables.
