Modern smartphones like the Xiaomi Redmi 8 often fail because of mechanical damage to the body. Broken rear window is one of the most common problems faced by users of budget devices. If you are thinking about how to open the cover Xiaomi Redmi 8, then it is time for a careful repair.
Disassembly requires not only special tools, but also patience, as well as understanding the structure of the device. Failure to comply with safety regulations can lead to damage to plumes or battery bloating. In this article, we will discuss in detail each step of dismantling the rear panel.
Before you start physically affecting the body, you need to make sure that you have all the necessary equipment. The adhesive base in modern smartphones holds the parts very tightly, so you can not do without heating and special tools. Prepare a workplace with good lighting, so that you do not lose small screws.
Necessary tools for disassembly
To successfully complete the dismantling procedure, you will need a minimal but specific set of tools. Using inappropriate items such as knives or pins can lead to short circuits or scratches on the internal components. Professionals use specialized opening kits.
The main tool will be a hair dryer or a thermophene, and it's the thermal action that softens the adhesive layer that holds the glass, and you'll also need a suction cup, a mediator, or a plastic blade to snap the latches, and you'll want to avoid using metal tools to avoid damage.
- 🔧 Sets of screwdrivers (required presence of Torx) T5 or Phillips #00)
- 🔥 Dryer or thermophen for heating the body
- 📱 Plastic blades and mediators
- 🧲 Magnetic mat or organizer for screws
- 🧴 Fluid B-7000 or special glue for assembly
Special attention is paid to the choice of suction cup. For Redmi 8, the best suction cup with a ring-handle, which ensures a reliable grip on the smooth surface of the glass. If the suction cup is weak, you risk ripping it at the most critical moment, damaging the screen.
⚠️ Warning: Before starting work, be sure to turn off your smartphone. Attempting to open the device with the battery on can lead to a short circuit and fire.
Preparation of the device for autopsy
The first step in preparation is to remove the tray for SIM-It's standard procedure, but it's critical: if you forget to pull out the tray, you can damage the mechanism or the tray when you try to remove the lid. Use a paper clip or a special needle that comes with it.
Next, heat the perimeter of the back cover. Warm up the edges of the smartphone evenly with a hairdryer for 2-3 minutes. The temperature should not be extreme, 80-90 degrees Celsius is enough. If you overheat the device, you can damage the display matrix or internal plumes.
💡
Check the heating of the body with your hand - it should be hot, but tolerant to touch. If the finger burns, let the device cool down a little.
Once heated, immediately glue the suction cup at the bottom of the back cover, stepping away from the edge about 2 centimeters. Pull the suction cup upwards, creating a small gap between the glass and the frame. Insert a plastic spatula gently into the resulting gap.
Rear detachment process
The most important thing is to walk around the perimeter of the device with a plastic card or a shoulder blade. Move slowly, do not make sudden jerks. The glue in the Xiaomi Redmi 8 is unevenly distributed, and in some places you will need to reheat.
Start from the bottom, gradually climbing to the side faces. Try to keep the blade parallel to the body so as not to touch the internal components. The fingerprint scanner plume can be located close to the edges, so the depth of the instrument should not exceed 3-4 mm.
What to do if the lid does not move?
When you pass the perimeter, the back cover should be easy to separate, but don't rush to tear it off abruptly. There may be thin strands of glue or a plume trapped inside, and carefully lift the glass and visually check for connections.
Disconnection of plumes and removal of components
Once the lid is removed, you have access to the insides, and the first thing you need to do is turn off the battery, which is a critical step that prevents the device from accidentally turning on and surges in the future.
The battery in Redmi 8 is connected via a connector at the bottom of the motherboard. Carefully tuck the connector into a plastic spatula. Don't use metal objects to avoid closing contacts on the board.
| Component | Location. | Type of attachment | Features |
|---|---|---|---|
| Battery | The bottom part | Plate + glue | Requires careful shutdown |
| Camera module | Upper left corner | schleife | Fragile, afraid of statics |
| Dynamician | Lower end | Screws + connector | Closed by a grid. |
| Charging charges | Bottom of the hull | Train + screws | Often times, replacements are required. |
If you want to replace the battery or repair the board, you can now safely extract the modules you need to remove the motherboard itself, you need to unscrew a few screws hidden under decorative plugs, and remember the location of each screw.
☑️ Safe disassembly
Common mistakes in the dismantling of the Redmi 8
Many users make mistakes that make simple repairs a difficult problem, and one of the most common is trying to plug the volume buttons in the area, where there are plumes, and the risk of damage is almost 100%.
Another mistake is ignoring the screws under decorative stickers. Xiaomi's back often hides fasteners. If you pull with effort, you can tear off part of the body along with the screw, which will make assembly impossible without replacing the frame.
⚠️ Warning: Never use force unless something unscrews or snaps. You've probably missed the screw or not warmed up enough.
Also worth mentioning is static electricity, whether you're running on an antistatic mat or at least a clean wooden surface, and static discharge can disable a power controller or touchscreen, even if nothing visually burns.
Assembly and sealing of the shell
After the repair work, you need to properly assemble the device. Before installing the back cover, remove the residue of old glue from the frame and the glass itself.
Use a special glue sealant, such as a B-7000 or T-7000, to fix the lid, apply it with a thin strip along the perimeter of the frame, avoiding hitting the camera and speaker, remove the glue immediately before they freeze.
💡
Quality sealing is not only aesthetics, but also the protection of internal components from dust and moisture, which prolongs the life of the smartphone.
Press the lid and hold it with rubber bands or a load for 1-2 hours until the glue is completely dry. Don't turn the phone on immediately, let the chemical components of the glue polymerize. Full strength of the compound is gained after 24 hours.
