Xiaomi Redmi Note 5A Prime: How to make it out

The process of self-repair or upgrade of the smartphone Xiaomi Redmi Note 5A Prime requires from the wizard not only accuracy, but also a deep understanding of the design of the device. Unlike the flagship models with all-metal cases, this device is assembled on a plastic frame, which somewhat facilitates access to internal components, but requires special attention when working with adhesive joints. Before starting to dismantle, you need to clearly understand the purpose of the intervention, whether it is to replace a broken display, install a new battery or clean the speaker from dust.

It's important to understand that any mechanical impact on the body automatically deprives the device of warranty if it's still in operation. To successfully perform the operation, you'll need a minimal set of tools: a thin plastic blade (mediator), a set of PH0 and PH00 screwdrivers, a suction cup to lift the lid and tweezers. Ignoring safety rules or using a poor-quality tool can damage the plumes, which will turn a simple repair into an expensive replacement for the motherboard.

Particular attention should be paid to the condition of the battery before work, if the battery is swelled or damaged, it should be used with extreme care to avoid causing a fire. It is recommended to discharge the device to a level of 15-20% to minimize the risks of accidental short circuit of contacts during disassembly.

⚠️ Warning: Before any manipulations, be sure to turn off your smartphone. Working with the device on can lead to irreversible damage to electronic components.

Preparation of the workplace and tools

Quality workspace preparation is the key to successful disassembly Xiaomi Redmi Note 5A Prime. You will need a spacious table with good lighting, where nothing will interfere with the view of small details. Organize the space so that all tools are in range, and small screws can not roll into hard-to-reach places.

A magnetic mat or cell container is ideal for collecting and sorting fasteners. The screws in modern smartphones can vary in length even within a single node, so messing them up can damage the board or body when you build them. Also prepare a soft fabric or silicone mat so that you don't scratch the back of the device while you're working.

Be sure to have isopropyl alcohol and a thin brush on hand, which will help to gently clean the contacts of oxides or remove the remnants of old glue, which often remains on the frame after removing the back cover. The use of aggressive solvents or water is strictly prohibited.

• 🛠️ A set of precision screwdrivers with magnetic tips for reliable grip of screws.
• 🔧 Plastic blade or mediator to open the case without damaging the plastic.
• 🧲 Magnetic mat or organizer for sorting screws of different sizes.
• 🧴 Isopropyl alcohol for degreasing surfaces and cleaning contacts.

Removal of the back cover of the smartphone

Design of Xiaomi Redmi Note 5A Prime involves mounting the back panel on a two-part glue around the perimeter and several screws under plugs. SIM-After that, carefully inspect the perimeter of the device for visible screws, although in this model they are usually hidden by a decorative strip or they are absent in favor of adhesive joints.

To separate the cover, it is recommended to preheat the perimeter of the case. Use a hair dryer or special heater, setting the temperature no higher than 80-90 degrees Celsius. This will soften the adhesive layer, making it more elastic and allowing you to separate parts of the body without the risk of breaking plastic latches. Keep at a distance of 5-7 cm from the surface and warm the edges evenly for 2-3 minutes.

After warming up, insert the suction cup at the bottom of the back cover, closer to the speaker, and slightly pull up, creating a small gap. In the resulting gap, carefully insert a plastic blade and lead it along the perimeter, gradually snapping the glue. The movements should be sliding, not stabbing, so as not to damage the fingerprint scanner plume if it is connected to the cover (in this model, the scanner is usually on the plume going to the board).

Dismantling the internal framework and protection of fees

Once you successfully remove the back cover, you'll see a plastic frame that covers the main components, and underneath it is the battery, the motherboard and the camera module, and this frame is mounted on a set of screws around the perimeter and possibly in the center, and all screws must be twisted counterclockwise, with the utmost care.

The area around the main camera module and the flash requires special attention. The screws here can be of different lengths, and if you screw a long screw into a short hole, you can damage the circuit board or the camera module itself. It is recommended to photograph each stage of the untwist or use a screw layout scheme.

Removing the plastic frame gives you full access to the battery, but before you touch the internals, you need to disconnect the battery plume from the motherboard, a critical step that shuts down the device and prevents short circuits from further disassembly.

💡

Use a plastic card or a spatula to turn off the plumes. Metal tweezers can damage the connector contacts on the board.

Replacement of the battery and work with glue

In the Xiaomi Redmi Note 5A Prime, the battery is mounted on two strips of double-sided tape. Do not use sharp metal objects to extract it, which can pierce the battery body.

The optimal method of extraction - reheating the lower part of the body with a hairdryer to 60-70 This will weaken the adhesive layer. Then use a thin plastic blade or a special suction hood to gently lift the battery. Move the tool progressively, trying not to deform the battery itself.

When installing a new battery, be sure to remove the remnants of the old glue from the phone body.The surface should be clean and fat-free. Use special adhesive strips (B-7000 adhesives are best avoided, as it will make future repairs difficult) or 3M double-sided tape to fix the new battery.

⚠️ Warning: Never bend the battery or force it to the center. Deformation of the inner layers can cause an internal circuit even without external damage.

Access to charging connector and dynamics

The bottom of the smartphone, where the Micro-USB connector and main speaker are located, often requires cleaning or replacement. Mud and pile stuffed into the charging port are a common cause of poor contact. To get to this node, you need to completely remove the motherboard or gently disconnect the plume going to the bottom board.

The plume that connects the main and bottom boards runs along the battery and is fixed by a downbar, unscrew the screws of the bar, lift it with tweezers, and then turn off the train, and the movement should be strictly upwards, without distortion, so as not to damage the contacts.

The speaker in this model is integrated into a plastic module. If the sound becomes quiet or hoarse, try gently blowing the speaker grid or brushing it with a soft brush. If you change the module, make sure that the rubber seal fits tightly to the body, otherwise the sound will go inside the phone.

• 🔌 Micro-USB connector often requires replacement due to loosening of contacts.
• 🔊 The speaker can become polluted by dust, which reduces the volume of playback.
• 📱 The plume of the connection of the boards is a fragile element that requires careful handling.
• 🛡️ Pressing slats are required to be installed for connection reliability.

Assembly of the device and verification of functionality

The Xiaomi Redmi Note 5A Prime is assembled in a strictly reverse sequence. Before installing the back cover, be sure to check the health of all systems: turn on the phone, check the sensor, camera, sound, vibration and charging. Make sure all plumes are snapped to the characteristic clicks.

Sticking the back cover requires a new layer of glue. Use a thin strip of special electronics glue (e.g., B-7000) around the frame, avoiding getting into the camera and speaker. Press the cover and lock the device with rubber bands for 15-20 minutes before initial grasping.

Don't twist the screws of the protective frame too much - the plastic can crack. Easy enough. After full assembly, wipe the case with a soft cloth to remove traces of fingers and glue.

💡

The main mistake in assembly is trying to close the lid without checking the phone. Always test the device before the final gluing of the case.
