Xiaomi’s Redmi series has proven to be reliable, with excellent value for money. However, like any electronics, Redmi 5 (codenamed “roses”) may require intervention over time, whether it’s a swollen battery, broken display glass, or the need to clean the speaker from dust — knowing how to open the device properly will save you money on the service.
The process of opening this model has its own nuances related to the design of the case and the location of the plumes, and improper actions can lead to damage to internal components or loss of warranty, if it is still valid.
In this article, we will discuss in detail what tools will be required, how to safely detach the back cover and what to do if it does not lend itself. You will learn where the hidden screws are and how not to damage the fingerprint scanner plume during dismantling.
Tools and workplace preparation required
Before you start, you need to prepare your workspace, you need a clean, well-lit desk, preferably with antistatic coating or just no pile. (chaos) on the table is the master's main enemy, as small screws are easy to lose.
The main tool for opening Xiaomi Redmi 5 will be a suction cup or a thin mediator. the back of the device is held on plastic latches around the perimeter, so the mechanical impact must be point.
You’ll also need a set of screwdrivers, which should include a P2 cross (or P000 for small screws) and perhaps a Torx T5 star, although this model uses standard screws more often.
- 🛠️ Suction cup to lift the lid or thin knife (with caution).
- 🔧 Screwdrivers (Cross Phillips #000 or #00).
- 📱 Plastic blade or mediator for opening.
- 🧲 Magnetic mat or screw sorting container.
- 🌡️ Dryer or heat heater (optional, for softening glue).
⚠️ Note: Using metal tools (knives, metal blades) to (poke) the lid is highly discouraged.The metal can damage the inner frame, tear plumes or, worst of all, close the contacts of the battery, causing a fire.
💡
Before starting disassembly, be sure to completely discharge the battery before turning off the phone, which will reduce the risk of short circuit in the event of accidental damage to the power chain.
Rear cover removal and access to the insides
Redmi 5 Disassembly Begins With Deletion SIM-It's a standard procedure that allows you to access the first screw hidden under the tray. Remove the tray with a clip from the kit.
Then you unscrew the two screws, which are located at the bottom of the case on the sides of the Micro-USB charging connector. Once they're removed, you can proceed to the most difficult part, the rear panel separation, which is attached to a lot of plastic latches around the perimeter.
Insert the suction cup into the bottom of the back cover, closer to the MI logo, and gently pull upwards, creating a small gap. Insert a plastic card or mediator into this gap. Drive the tool along the faces, slightly pressing inwards to release the latches.
☑️ Preparation for opening of the hull
Move slowly, don't jerk. Plastic on older devices can be fragile. If the lid doesn't lend itself, you can slightly warm the perimeter with a hairdryer to 60-70 degrees, but don't overheat the display.
Once all the latches are clicked, gently lift the lid, and here's an important caveat: the fingerprint scanner plume is glued to the inside of the lid, so don't throw the lid back out so as not to break this thin conductor.
Disconnection of the battery and dismantling of the protective plate
When you remove the back cover, you'll see the interior layout, and on the top, under the black plastic protective lining, you'll see the main connectors, and you'll need to twist 10 screws to access them.
The screws can be of different lengths, and experienced craftsmen advise you to lay them out in the same order in which they were twisted, or use a special pattern card, and if you confuse the screws, you can damage the motherboard when you reassemble them.
When you take off the plate, you'll see the display connectors, the camera plume, and most importantly, the battery connector. First thing you need to do is turn off the battery. Use a plastic blade to gently snap the plume.
⚠️ Note: It is strictly forbidden to disconnect or connect any plumes until the battery is disconnected from the motherboard.The presence of voltage in the circuit can cause the power controller or backlight screen filter to burn.
Once the battery is turned off, you can safely work with other components, and if you plan to disassemble completely, you now need to disconnect the antenna cables (black and white/gray) that run from the Wi-Fi modules to the upper and lower antennas.
Nuances of antenna cables
Extraction of motherboard and modules
To remove the motherboard, you need to free it from all mounts. In addition to the main screws, look for screws hidden under stickers or in the depths of the case. In the Redmi 5, you also need to remove the main camera module, which may interfere with access to some screws.
Carefully disconnect the main camera plume and flash, and the camera in this model is quite massive and tightly attached, and once all the plumes and antennas are turned off, the board should be freely removed from the case.
And remember, the subboard, where the charging connector and the bottom microphone are, is connected to the main board by a plume that runs along one of the side faces, and you also have to turn it off.
- 📷 Disconnect the main camera plume and flashes.
- 🔌 Disable the lower board plume (charging).
- 📡 Disconnect antenna wires from modules.
- 🔋 Remove the vibromotor if it interferes with access.
When removing the board, be careful with the side buttons (volume and power) that can get stuck in the openings of the case, it is better to gently push them from the inside before the final jerk.
Replacement of battery and screen
Most often, Xiaomi Redmi 5 is disassembled specifically to replace the battery. The battery in this model is glued to the frame with double-sided tape. To remove it, it is recommended to use a suction cup and, if necessary, warm the rear wall of the case (if the battery is still inside) or the battery itself through an open lid.
Never try to tamper with sharp objects or tools with teeth. A puncture of a lithium polymer cell will cause instant ignition. Use a plastic card soaked in isopropyl alcohol to dissolve the glue.
When installing a new battery, make sure that the contact pad on the battery plume is clean. Stick a new two-way tape onto the body before fixing the cell.
| Component | Difficulty replacing | Risk of damage | The necessary tool |
|---|---|---|---|
| Battery | Medium | Tall (fire) | Suction, hair dryer, plastic |
| Screen (module) | Tall. | Medium. | Screwdrivers, spatula |
| Lower fees | Low. | Low. | Screwdriver cross |
| Camera. | Low. | Medium (train) | Plastic spatula |
If your goal is to replace the screen, the process is complicated by the fact that Redmi 5 has a framed module, you have to transfer the motherboard, batteries and all the small parts from the old broken module to the new one, which requires increased care and cleanliness.
💡
When changing the screen, always check the touchscreen and matrix until the final assembly of the case, which will save you from re-disassembling in the event of a new part failure.
Assembly of the device and verification of functionality
The assembly is done in reverse order. But there are a few critical issues: first, make sure that all screws are twisted with the same force, a twisted screw can crack the plastic rack inside the case, and an untwisted screw can cause a backlash.
Second, when you install the back cover, first hook the top (near the camera), then gently press the perimeter until all latches click. Make sure the fingerprint scanner plume is not caught by the screws and is not squeezed.
After assembly, but before the external screws are finally twisted, it is recommended to plug in the battery and turn on the phone. Check the sensor, speakers, microphone, cameras and Wi-Fi.
⚠️ Warning: If the phone doesn't turn on after assembly, don't rush to disassemble it again.Plug in the original charger and wait 15-20 Deep discharge could have gone into defense, and the phone needs time to rock".
Only after making sure that all systems are fully operational, you can finally fix the screws and install them. SIM-A properly assembled Redmi 5 should not have creaks when the body is compressed and visible gaps between parts.
