How to carefully remove the back cover on Xiaomi Redmi 5A: instructions with photos and tips

Introduction: Why it’s harder than it seems

Removing the back cover of the Xiaomi Redmi 5A is a task that seems simple at first glance, but many users experience plastic creaks, body cracks, or even damage to plumes on their first attempt, because the manufacturer uses hidden latches and adhesives that are not visible from the outside, but play a key role in the integrity of the structure.

This model, which was released in 2017, has become one of the most popular models in the budget segment because of its reliability, but it's budget execution that means that the plastic is thinner here, and the mounts are fragile than the flagships. SIM-It is important to understand that one wrong movement can turn into expensive repairs.

In this article, we will explore not only the step-by-step process, but also alternative methods (such as using a hair dryer), as well as what tools are really needed and what can be done without, you will learn how to avoid typical mistakes and what to do if the lid does crack.

Preparation: What will be needed for the job

Before you start, make sure you have everything you need, and if you don't have at least one tool, you can permanently damage the body or the internal components, and here's the minimum set:

• 🔧 Plastic blade (or mediator) - to disconnect latches without scratches.
• 🔥 Hair dryer (optional, but useful for softening glue).
• 📱 Suction cup (helps to lift the lid after heating).
• 🔋 Screwdriver. T3 or T4 (for the screws under the cover, if you plan a full analysis).
• 🧴 Isopropyl alcohol (for cleaning glue residues).
• 📦 Container for screws (so as not to lose small parts).

Important: Don't use metal tools (knives, screwdrivers) to slap the lid! Even the gentle pressure will leave microcracks that will eventually turn into full-fledged faults. Redmi 5A plastic is particularly vulnerable to point loads.

If you are going to replace the battery or clean the motherboard, additionally prepare:

• 🧤 Antistatic bracelet (protection against static electricity).
• 🔍 Lupa (for inspection of small details).
• 📏 Tweezers (for working with plumes).

⚠️ Attention: If your Redmi is 5A If you were in high humidity or had a fall, the internal mounts might have weakened, and if you did, the lid might be too easy to remove, which is a sign of a damaged body structure, and you'd be prepared to have the phone reassembled and you'd need to glue it together.

Step 1: Power outage and withdrawal SIM-map

The first and mandatory step is to shut down the device completely. Even if the battery is dead, the Redmi 5A can retain a residual charge in the capacitors, which will result in a short circuit when the board is accidentally touched.

Instructions:

1. Press the power button for 10 seconds to make sure it is off.
2. Remove the tray for SIM-cards with a paper clip (hole near the camera).
3. If the phone does not respond to the power button, plug it into charging for 1-2 minutes, then try to turn it off again.

Why it matters: Contacts SIM-The tray is connected to the motherboard, and if you accidentally touch them with a tool when the lid is removed, it can cause damage to the communication module (up to the loss of the network).

If your Redmi 5A doesn't turn on and respond to charging, the problem may be the power connector or battery, in which case you need to remove the lid especially carefully - there may already be damage inside.

Step 2: Heat the body (optional, but recommended)

The glue that glues the cover Xiaomi Redmi 5A loses its properties when heated to 50-60 ° C. This greatly facilitates the removal process, but requires caution:

• 🔥 Use a household hair dryer at minimum power.
• 🕒 Heat the cover for no more than 2-3 minutes, keeping the hair dryer at a distance of 10-15 cm.
• ⚠️ Avoid overheating the area around the camera and the charging connector – there are thermally sensitive components.

Alternative method: If there is no hair dryer, you can put the phone on a warm battery or in a bag with warm (not hot!) water for 5-7 minutes.

⚠️ Warning: If the lid fails after heating, do not apply force! This means that the glue has not softened enough or the latches have not released. Reheat again or try an alternative method (for example, using a suction cup).

Step 3: Separation of the cover and the body

Now, to the most critical point, it's important to take your time and follow a clear algorithm.

1. Start at the bottom edge (near the charging connector). Insert a plastic blade into the gap between the lid and the body.
2. Carefully drive the shoulder blade along the edge, releasing the latches one by one, and you'll hear the characteristic clicks.
3. Do not lift the cover too high - there are display plumes and buttons under it.
4. Once 2/3 of the perimeter is freed, the lid should be easy to separate, and if not, check to see if the corners are unlatched.

If you're taking the lid off for the first time, we recommend taking a picture of the process, which will help you put the phone back together properly.

• 📸 Location of glue residues (they will need to be cleaned before reassembling).
• 🔧 Position of screws (they may differ in length).
• 🔌 Connecting plumes (they are easy to damage with careless movement).

💡

If the lid cracks when you remove it, don't panic. Carefully collect all the fragments and use cyanoacrylate glue (like "Moment") to bond, apply the glue in a thin layer and fix the lid with tape for 12 to 24 hours.

Step 4: What to do after removing the lid

Congratulations! If you've reached this point, the hard part is over. Now you've got the insides of the Xiaomi Redmi 5A, and here's a few rules to follow.

• 🚫 Don’t touch the motherboard with your bare hands – static electricity can damage the chips.
• 🔋 Battery glued to the case - do not pull it by the wires!
• 📱 Display plumes and buttons are fragile - fix them before completely removing the lid.

If your goal is to replace your battery, follow these steps:

1. Unplug the battery by smacking it with a plastic spatula (start at the top edge).
2. Disconnect the power plume from the board (use tweezers).
3. Install a new battery, pre-clean contacts with alcohol.

To clean the connectors (for example, charger or headphones) use:

• 🧹 Soft brush (for example, for drawing).
• 💨 Compressed air canister.
• 🧴 Cotton swabs dipped in alcohol.

⚠️ Warning: If you notice a bloated battery, stop all manipulations immediately! This battery is dangerous - it can ignite if damaged.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when parsing the Redmi 5A. Here are the most common ones and ways to prevent them:

💡

The most common cause of breakdowns in the Redmi 5A is rush. If the lid doesn't lend itself, it's better to take a break, reheat the body and try again than to apply excess force.

Another common problem is the loss of propellers, and the Redmi 5A only has 8 or 10 screws, but they vary in length, and if you mix the long and short screws in some places, you can get:

• 🔧 Damage to the motherboard (if the screw is too long).
• 📱 The slenderness of the lid (if the screw is short).

To avoid this, spread the screws in order of their extraction or use a magnetic mat with markings.

Phone Assembly: How to Avoid New Problems

Xiaomi Redmi 5A reverse build is as responsible as disassembly. Here are the key points:

1. Clean the adhesive residues from the lid and body with alcohol. New glue (for example, B-7000) apply a thin layer.
2. Check the plumes – they should be tightly connected, but without inflections.
3. Twisting the screws cross-cross to avoid skewing the cover.
4. Check the buttons (on, volume) before final assembly.

After assembly:

• 🔋 Connect your phone to charge and make sure it correctly identifies the battery.
• 📶 Check the network signal and operation Wi-Fi/Bluetooth.
• 🔊 Test the speaker and microphone (sometimes the plumes of sound will depart when assembled).

If the phone does not turn on after assembly, check:

• 🔌 Battery connection (possibly the plume has gone away).
• 🔧 Tightening of screws (uncut screws can cause a circuit).
• 📱 Contacts of the power button (sometimes they stick after parsing).

💡

If the lid creaks or wobbles after assembly, it's a sign that the glue isn't dried or the screws are twisted unevenly. Take the phone apart again, clean the surfaces and repeat the assembly.
