Modern smartphones like the Xiaomi Redmi 8 Pro are designed with an emphasis on aesthetics and protection from external influences, making them quite a difficult process to disassemble independently. The adhesive base that holds the back cover requires careful heating and careful intervention to avoid damaging fragile internal components. Many users decide to take this step to replace a broken screen or a swollen battery, saving on the services of the service center.
However, before you start physically affecting the device, you need to be clear about the risks: the warranty seal will be broken, and inept actions can lead to the failure of the motherboard. In this article, we will discuss the dismantling process in detail to minimize the likelihood of errors and help you successfully perform repairs with your own hands.
Workplace preparation is as important as tools. You'll need a clean, well-lit surface, preferably with an antistatic coating, to prevent static damage to electronics. The Redmi 8 Pro has a glass back panel that can crack when handled carelessly even with light pressure.
For high-quality and safe disassembly of Xiaomi Redmi 8 Pro standard set of screwdrivers will not be enough. You will need a specialized tool that will work with adhesive joints and thin plumes. Ignoring this stage can damage the fasteners or rupture contacts.
First of all, get a hair dryer to warm up the case, but do not use an open-spiral construction dryer, as it can overheat the battery. Thermal pads and adhesive base under the display melt at a temperature of about 80-90 degrees, which is safe for the body, but dangerous when directly in contact with your fingers.
- 🛠️ Precision screwdrivers (Pentalobe and Phillips crosses).
- 🔥 Dryer or heat heater for uniform heating of the back cover.
- 💳 Plastic cards or mediators for opening the case without scratches.
- 🧲 Magnetic mat for sorting screws of different sizes.
- 🧤 Antistatic gloves and dielectric-coated tweezers.
⚠️ Warning: Before starting any work, be sure to turn off the smartphone from charging and wait for it to cool completely if it was in use. Working with a hot device increases the risk of burns and accidental short circuit.
So, you have to focus on space management, and the different screws in the Redmi 8 Pro are different in length and in thread, and if you mix them up with the parts you build, you can damage the carvings in the plastic, or worse, you can break through the motherboard with a long screw, and you can avoid chaos by marking the disassembly steps.
Removal process of the back cover
The most difficult step in dismantling Xiaomi Redmi 8 Pro is the separation of the glass back from the metal frame. Manufacturers use aggressive adhesive around the perimeter, which securely fixes the elements. Start heating should be at the ends of the device, paying special attention to the corners where the adhesive layer is usually thicker.
Heat the perimeter of the phone during the 2-3 You can't go over the temperature with your hand, you can't go over the temperature. 90 degrees, otherwise there is a risk of damage OLED-If you have a back display, or you blow up the battery, once the case is warm, try putting a plastic mediator in the junction between the glass and the frame.
Move the map along the perimeter, gradually cutting through the adhesive layer. Don't try to slap the lid sharply or use metal blades - Redmi 8 Pro glass is very fragile. If you feel strong resistance, warm up the problem area again with a hairdryer.
⚠️ Note: It is strictly forbidden to insert tools deeper 3-4 And at this depth, there are side button plumes and the main charging connector, which damage the body.
Once the lid has been successfully removed, put it in a safe place, and inside you'll see a plastic lining covering most of the components, and it can also be held on screws or latches that require careful handling.
What to do if the back cover is broken?
If the back window bursts during heating or opening, do not try to collect the fragments with your bare hands. Carefully paste a wide transparent tape over the cracks to fix them, and continue dismantling. Once the repair is complete, the glass can be replaced entirely or use a special glue for the glass if the crack is not through.> Dismount the protective panel and the battery under the back cover hides a long plastic panel that presses the plumes and protects the top. To remove it, you need to twist all visible propellers into the Pro, after the revision, the battery number of which can be hidden in the battery 8. To extract it, use a special suction hood or gently tuck the edge with a plastic map, preheat the area under the battery. It is important not to damage the battery shell with sharp objects. The lithium polymer cell can catch fire when punctured or release caustic fumes. If the battery is swelling, you need to work with caution, fixing its position, so as not to press harder.Component mounting type Risk of damage Tool Rear cover Glue around the perimeter High (glass) Fen, mediator Protective panel screws + Latches Medium (plastic) Screwdriver, blade Battery Adhesive tape Critical (chemistry) Suction, map Trains Clamping connectors High (electronics) Tweezers, plastic When disconnecting the battery plume always use a dielectric tool. Redmi 8 Pro is sensitive to short circuits, and the accidental connection of connector contacts can bring the power controller out of action instantly. Replacing the display and camera module Get to the display in Xiaomi Redmi 8 Pro only after the complete removal of the front panel or neat detaching of the plumes going to it. In most cases, it is recommended to completely remove the "stuffing" from the frames to access the screen mounts from the back. The main camera module is fixed in a separate unit and connected with a wide plume. When removing it, remember about the stabilization of the old camera, if it is often made with a touch perklach. Replacing glass separately from the matrix at home is almost impossible without a laminator and a separator. 📸 Turn off the main camera plume by pulling a special tongue. 🖥️ Remove the dynamic speaker that may interfere with access to the display plume. 🔌 Disconnect the display connector, having previously bent the fixing metal plate. 🧹 Wipe the new dust frame before installing the new screen. When installing the new display, make sure the plume is flat and securely fixed with a downbar. Unpressed connector is a common cause of missing images or "dead" areas of the touchscreen after assembly. 📊 What is most often broken in Redmi 8 Pro?Rear glass Display and glassCamera (frame)Other Assembly and check of operabilityAssembly Xiaomi Redmi 8 Pro is in reverse order, but requires even greater care. Before you turn the screws and glue the lid, you need to conduct an initial diagnosis. Connect the battery and the display plume, then press the switch on. If the device is activated, check the basic functions: The touchscreen is running throughout the area, the volume and power button response, and the cameras are running, and testing at this point will save you time to re-disassemble if the parts fail, and once you're sure you're working, install all the safety plates and twist the screws. For the back cover, use a special glue. B-7000 or T-7000, Put it in a thin layer around the perimeter, and remove the glue immediately before it freezes. ⚠️ Warning: Do not turn the phone on immediately after applying glue to the back cover. Let the device lie under load (evenly distributed) at least 1-2 The final step is to clean the case of the glue and fingers. If it goes well, your Redmi 8 Pro is ready for active use again. 💡The quality of the repair depends on the cleanliness of the work and the use of original or quality spare parts. Can you disassemble the Redmi 8 Pro without a hairdryer? Theoretically, using isopropyl alcohol, which is launched under the edges of the lid with a syringe. But this method is extremely risky for electronics and display, because liquid can leak in and damage components. Heating remains the safest way to soften the adhesive. Which glue is best used for the back cover? The best choice is specialized adhesives based on cyanoacrylate with flexibility, such as: B-7000 or E-8000. They provide reliable fixation, but on the next repair, they allow you to remove the lid using heating, unlike superglue. What if the touchscreen doesn't work after assembly? Most likely, the display plume or touchscreen isn't deep enough into the connector or squeezed in. Reassemble the device, check the connectors for contamination and reconnect them to the characteristic click. Should I change the heat pads when disassembling? If the old heat pads are intact and have retained elasticity, they can be reused. However, for the Xiaomi Redmi 8 Pro, which is prone to heat, it is recommended to replace the thinner gask with new similar thickness for better heat sink.
