How to gently open the back cover Xiaomi Redmi Note 6 Pro: detailed instructions with photos and warnings

Why do you need to take down the Redmi Note 6 Pro?

The back cover of the Xiaomi Redmi Note 6 Pro is not just a decorative element, but a complex design that protects the internal components of the smartphone. Users most often resort to removing it in three cases: battery replacement (the capacity of the original is 4000 mAh, but over time it decreases), dust cleaning (especially important for devices operated in dusty conditions), or repair after a fall – for example, if the vibrator engine fell off or the camera plume departed.

However, not everyone knows that improper opening of the body can lead to loss of leakage. IP-If you had one, it could be a class of malfunctioning, or a malfunctioning of the flexible plumes attached to the motherboard, such as the fingerprint scanner plume on this model being extremely fragile, right under the lid, and even a microscopic tear would render the sensor inoperable.

Before you start, consider your own strength: if you've never taken a smartphone apart, you'd better go to a service center, but if you're confident in your skills, this guide will help you do it carefully and without consequences.

What tools will be needed to remove the cover

You can't do a typical screwdriver to disassemble the Redmi Note 6 Pro, you'll need a customized kit that you can buy on AliExpress or in electronics stores. Here's the full list:

• 🔧 Plastic spatula (suction cup) + mediator: to separate the lid from the body, you can't use metal tools, they scratch the plastic.
• 🔩 Screwdriver. T3 and T5 — for unscrewing screws holding the metal frame under the lid.
• 🧲 Magnetic mat or organizer - so as not to lose small parts (screws, gaskets).
• 🔥 Hair dryer or thermoair station - for softening the glue (optional, but simplifies the process).
• 🧴 Isopropyl alcohol (90%+) — cleaning the residue of glue after removing the cover.

If you plan to reuse the lid, buy a double-sided 3M tape or a special glue B-7000 for fixing after assembly. The original Xiaomi adhesive is disposable - after removing the lid, it will have to be replaced.

Step-by-step: how to remove the back cover

The disassembly process takes 15-30 minutes depending on the experience, and follow the instructions strictly in order to avoid damaging the components.

1. Turn off your smartphone and remove it. SIM-You don't have to turn off the battery, it's done later.
2. Heat the edges of the cover with a hair dryer (~60°C) for 2-3 minutes. This will soften the glue. Don't overheat - the plastic can deform!
3. Insert a plastic blade into the gap between the lid and the case at the USB-Type C connector. Carefully guide it around the perimeter, separating the lid.
4. Remove the lid when all the latches are disconnected. Don't pull it too hard, there may be plumes glued underneath.

Under the lid, you'll see:

• 🔋 Battery with connector (disconnected first!).
• 📸 Camera plumes and fingerprint scanner.
• 🔊 Dynamics and vibrator.
• 🛡️ Metal frame, screwed with 10-12 screws.

Important! On the Redmi Note 6 Pro, the fingerprint scanner plume is glued to the lid with double-sided tape, and if you pull the lid too sharply, it will come off. To avoid this, put the plume in the shoulder blade and carefully separate it from the lid.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling the Redmi Note 6 Pro. Here are the most common of them and ways to prevent them:

⚠️ If you notice that the battery is swelling after the lid is removed (as seen from the deformation of the central part), do not continue disassembling! Bloated Li-Ion batteries can ignite when mechanically exposed. Take the device to a battery recycling service center immediately.

How to assemble the smartphone back: tips

Building the Redmi Note 6 Pro after repair is as much a process as disassembling. Here are the key points to pay attention to:

1. Clean the battery and plume contacts with isopropyl alcohol, which will remove the oxides and improve the connection.
2. Check the tightness: If the cover had rubber pads (such as around the speaker), make sure they are not torn and properly installed.
3. Use a new glue. The original Xiaomi adhesive loses its properties after the lid is removed. Apply a thin layer of B-7000 or double-sided tape around the perimeter.
4. Tighten the screws cross-cross to avoid distortion of the metal frame.

After assembly, turn on the smartphone and check:

• 🔋 Whether charging is working (plug the cable and make sure charging is underway).
• 📸 Are the cameras (front and main) functional).
• 👆 Does the fingerprint scanner recognize fingerprints.
• 🔊 Is there sound from the speaker and vibration.

1. whether the battery is connected to the motherboard (the connector may not be clicked).

2.Are there any clamped plumes under the lid?

3. Whether correctly established SIM-card (sometimes it blocks the inclusion).-->

What to do if something doesn’t work after the breakup

If you find that a module has stopped working after assembly, don't panic. 80 percent of the time, the problem can be solved without replacing the parts.

1. The fingerprint scanner is not working: Check if the plume is not removed from the motherboard. Clean the plume contacts with alcohol. Make sure the plume is correctly inserted into the connector (should be clicked).
2. No charge: Check if the charger on the motherboard is bent. Make sure the battery is connected to the board (sometimes the connector is gone). Try another charger, perhaps the cable problem.

No image from the cameras.

• Check to see if the camera plume is clamped.
• Make sure the camera connectors are connected to the board.
• Run the camera test through the engineering menu (#4636###).

If none of the items worked, it's probably the module itself or the motherboard that's damaged, and that's going to require a diagnostic at the service center, and for example, damage to the south bridge board (responsible for USB and charging) is a common problem after careless disassembly.

⚠️ If you have been disassembling a smartphone to replace the battery, but after assembly it discharges in a few hours, check: Is there a fake battery installed (the original is marked with a marking). MDY11). Is the controller chip on the board damaged (often suffering from short circuits) is background processes enabled (check Settings) → Battery).

Where to buy spare parts for Redmi Note 6 Pro

If you need parts -- battery, cover, plumes, or speaker -- it's important to choose a reliable seller. Here are the proven options:

When buying on AliExpress, pay attention to the reviews with photos - often sellers send parts from other models. For example, the battery from the Redmi Note 5 Pro looks similar, but has a different capacity (4000 mAh vs 3800 mAh) and does not fit!

💡

Before buying parts, always check their items with the original ones. For example, the battery for the Redmi Note 6 Pro has the number BH41 - this is a guarantee of compatibility.
