How to disassemble Xiaomi Redmi 5A Prime: a complete guide with photos and tips

Xiaomi Redmi 5A Prime is one of the most popular budget smartphones from Xiaomi, which is still actively used. However, over time, even such a reliable device can require repairs: a replacement battery, speaker, charging plume or even a motherboard. If you decide to disassemble the device yourself, it is important to do it carefully so as not to damage fragile components.

In this article, you will find a step-by-step photo guide that will help you safely disassemble the Redmi 5A Prime without the risk of breaking latches or tearing plumes. We will tell you what tools you need, how to remove the back cover correctly, remove the battery and get to the internal components.

Warning: disassembling the smartphone will void the Xiaomi warranty if it still works. If you're not sure about yourself, you better contact the service center. But if you're willing to take a risk, let's go!

What tools will be needed to disassemble the Redmi 5A Prime

Before you start disassembling, prepare everything you need, and without the right tools, you risk damaging the body or the interior, and here's the minimum set you'll need:

• 🔧 Plastic blade (or mediator) - for careful liding and disconnection of plumes.
• ⚡ Screwdriver cross (PH00 or PH0) — screw-off.
• 🔥 Dryer or thermoair station - to soften the glue under the battery (if you plan to remove it).
• 🧲 Magnetic mat or container – to avoid losing small screws.
• 📸 Smartphone for photography – capture each step so as not to confuse details during assembly.

If you are planning to replace the battery, prepare:

• 🔋 New battery (original or high-quality analogue, for example, from Baseus or Remax).
• 🧴 Isopropyl alcohol (90%+) — glue-residue.
• 🩹 Double-sided tape or glue B7000 — fixing.

⚠️ Warning: Do not use metal blades or knives to lick the lid! 5A Prime is quite fragile and metal can leave scratches or cracks.

Preparing the smartphone for disassembly: important steps

Before disassembling, you need to properly prepare the device, which will help to avoid short circuit, loss of data or damage to components.

Here's what we need to do:

1. Turn off your smartphone and remove it. SIM-card and memory card (if installed).
2. Charge the battery to 30-50%. A fully discharged or 100% charged battery can be more dangerous when dismantled.
3. Remove the cover and protective glass (if any) so that nothing interferes.
4. Blow the connectors with compressed air (optional) to remove dust that may get inside the enclosure.

We also recommend backing up the data, even if you don’t plan to touch the motherboard, and sometimes unforeseen situations (such as disconnecting the display plume) can occur during disassembly, which will lead to loss of information.

💡

If you're disassembling a battery replacement smartphone, pre-check its actual capacity with the AccuBattery app. Perhaps the problem isn't the battery, but the software failure.

How to Remove the Redmi 5A Prime Rear Cover

The Redmi 5A Prime back cover is mounted on latches and a small amount of glue, and you need to be careful not to break the plastic fixtures to remove it.

Instructions for removal:

1. Put the smartphone on a flat surface with the screen down.
2. Start putting the lid on the lower left corner (near the charging connector) with a plastic blade. Insert it no deeper than 1-2 mm so as not to damage the plumes.
3. Carefully drive the shoulder blade along the edge, alternately snapping the clamps, and you'll hear the characteristic clicks.
4. When most of the latches open, lift the lid, but don’t remove it completely – it can be connected to the fingerprint scanner plume (if your model is equipped with one).

If the lid doesn't lend itself, you can heat it up slightly with a hair dryer (temperature no higher than 60°C) to soften the glue, but don't overdo it - overheating can damage the plastic or display.

Battery Removal: Safety Above All

The battery in the Redmi 5A Prime is glued to the body, and removing it is one of the most critical steps.

Step-by-step:

1. Unscrew two screws that fix the metal plate above the battery (they are located next to the camera).
2. Carefully slap the plate and put it aside.
3. Pick up the battery with a plastic blade from any angle and try to lift it. If it does not lend itself, do not apply force - heat the body with a hairdryer (temperature 50-60 ° C) for 1-2 minutes.
4. When the battery starts to move away, put a thin plastic card or spatula under it and slowly separate it from the body, cutting the glue.

⚠️ Warning: If the battery is swelling (as seen from the bulge of the lid), do not try to pierce or bend it! This can lead to fire.

Dismantling the motherboard and other components

Once you take off the battery, you get access to the motherboard and other internal components, and it's important to be very careful, because the plumes and connectors are very fragile.

Procedure:

1. Unscrew all the screws that hold the motherboard (about 8-10 of them) and remember the location of each screw - they can vary in length!
2. Carefully unplug all the plumes: 📱 Display plume (located at the top of the board). 🔊 Dynamics and microphone plume (bottom). 📷 The camera plume (if you plan to take it off).

Put a plastic blade on the board and remove it from the case.

If you need to replace the speaker, vibromotor or charging connector, they are attached separately. For example, the USB-Type C connector is soldered to a small board that can be replaced separately (cost about 300-500 rubles).

Common mistakes in the Redmi 5A Prime

Even experienced craftsmen sometimes make mistakes that lead to a smartphone breakdown, and here are the most common ones and how to avoid them:

• 🔧 Loss or entanglement of screws. screws in Redmi 5A Primes are of different lengths, and if you screw a long screw into a place that's not intended for it, you can damage the board. Solution: spread the screws in groups or take pictures of their location.
• ⚡ Damage to the plume of the display, which is very thin and easily breaks when sloppy extraction. Solution: just pop the plume with a plastic blade, don't pull the wires.
• 🔥 Battery overheating. Many newcomers heat the case too much with a hairdryer, which leads to plastic deformation or battery fire. Solution: use a thermometer and don't go over 60.°C.
• 📵 They forget to turn off the fingerprint scanner plume, if you pull the lid too sharply, you can pull the plume off. Solution: Before you remove the lid, check if there are any additional attachments.

Another common problem is incomplete assembly, such as forgetting to plug in a speaker plume or vibrator, which causes the smartphone to malfunction after assembly, and to avoid this, use the checklist from the previous section.

💡

If the smartphone doesn't turn on after assembly, check the battery and power plume connection first. In 80% of cases, they are the problem.

Assembly of the smartphone after repair

The Redmi 5A Prime is built in reverse order, but it has its own nuances.

1. Check all the plumes for damage, and if you notice any tears, you'd better replace the plume before assembly.
2. Make sure the screws are screwed into the correct holes. Rotors of different lengths should not touch the components on the board.
3. Secure the battery with double-sided tape or B7000 glue. It should not hang around inside the case.
4. Check all buttons (on, volume) before final assembly. Sometimes they can be clamped by a board.

After assembly, turn on the smartphone and check:

• 📶 Network operation (SIM-The card determines whether there is a signal).
• 🔋 Charging (plug the charger and make sure charging is underway).
• 🎤 Microphone and speaker (call another phone or record a voice note).
• 📷 Camera (take a test shot).

If something doesn’t work, take the smartphone apart again and check the connection of the corresponding plumes.
