Disassembly/Repair of the mobile device Honor X7b (Honor X7b CLK-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 tray. For that, we use a special tool, insert it into the hole, and push the tray out.

Next, we need to heat the back cover to around 70 degrees Celsius or 160 degrees Fahrenheit. We're using a heating mat, but a hairdryer will also work.

After 5 to 10 minutes, we can start separating the back cover.

To do this, we use a thin plastic film. We carefully insert it into the gap between the back cover and the midframe, and gently slide it along the edge, cutting through the adhesive.

Be extra careful around the side buttons and fingerprint sensor area, as cables might be located there.

We also need to be very careful around the camera area, as the cover is more firmly glued there.

At some point, we can take a peek under the cover to check for remaining adhesive spots.

We can also use a thin tool to slightly lift the cover.

It's important not to press down on the area above the motherboard to avoid any damage.

To remove the screws, we use a 1.5 mm Phillips screwdriver or a Phillips #000.

We carefully unscrew them and lay them out in a specific order so nothing gets mixed up.

If any screw is stuck, we can use tweezers. If they’re hard to remove, we can also use a magnetizer.

For the screws at the bottom, it’s better to keep them separate from the others.

Please notice there's another barely visible black screw that holds the midframe and motherboard together.

There’s also one black screw on the side—it’s important to remove it.

Now we move on to removing the midframe.

For that, we use a thin plastic film to unclip a few clips near the SIM tray, then switch to a thicker tool. Be very careful at the corners, as the frame holds tightly there, and there's extra adhesive.

Gently release the clips—don’t force it open, or you might damage the flex cables or other parts under or on the frame.

We flip the cover in a way that doesn’t damage the fingerprint sensor cable that runs from the motherboard to the midframe.

Now, using a non-metal tool, we disconnect the battery connector.

ℹ️ The Honor X7b CLK-LX1 model has a battery HB4966A2EGW with a capacity of 6000 mAh (also known as a rechargeable battery).

Next, we apply protective film over the camera lenses to prevent dust or debris.

Now we disconnect the small rear camera.

And, we remove the small bracket that covers the fingerprint sensor connector.

We carefully remove the bracket and set it aside.

Now we can disconnect the fingerprint sensor connector and remove the midframe.

And we carefully detach the loudspeaker.

Then we disconnect the inter-board flex connector and the two coaxial cables.

Now we remove one screw that secures the sub-board. This screw is different, so we keep it separate.

So, now we can remove the sub-board. We gently lift and take it out.

The sub-board contains the charging port, microphone, headphone jack port, and other components on the reverse.

Now we move to the motherboard. We disconnect the inter-board cable, which also connects to the display. Then we disconnect the two coaxial cables.

And we disconnect the rear cameras. Gently remove the connectors, peel off the thermal foil, and set the cameras aside.

Next, we disconnect the front camera. It’s best to cover its lens with a film to keep it clean.

Now we can remove the motherboard. We find the right spot, gently lift it out.

The back may be held with thermal paste.

Finally, we remove the battery. HONOR phones have brown pull tabs. Carefully fold them aside, read the labels.

Try to release the edge tabs, then pull the center tab to remove the battery.

Under the battery, there’s a transparent protective layer covering the inter-board cable.

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