Step-by-step dismantling of Xiaomi Redmi Note 6 Pro: instructions for repairing with your own hands

Xiaomi Redmi Note 6 Pro is a popular smartphone that is still in use today for its reliability and good performance, but over time, even the best devices require repairs, whether it is replacing the battery, cleaning from dust, restoring the charging connector or replacing the display module, disassembling this device has its own nuances related to the design of the case, the location of the plumes and the type of mounts.

In this article, you will find detailed instructions on how to disassemble photos of key steps, a list of necessary tools and warnings about typical errors that can damage the board or display. We will also tell you how to properly disconnect the plumes so that you do not break contacts, and what to do if the smartphone does not turn on after assembly. If you have never disassembled a smartphone before, this guide will help to avoid common problems.

Preparation for disassembly: tools and security measures

Before you start disassembling the Redmi Note 6 Pro, make sure you have everything you need. Lacking at least one tool can complicate the process or damage the body.

• 🔧 Plastic mediators (2-3 (S) - for careful slapping of the lid and disconnecting the latches.
• ⚒️ The screwdriver (PH00 or PH0) — for the screws of the case and motherboard.
• 🔥 Hair dryer or thermal air station - to soften the glue under the back cover (optional, but recommended).
• 🧲 Magnetic mat or organizer – so as not to lose small screws and details.
• 📱 Suction cup for display - will help to remove the screen carefully (if you need to replace it).
• 🔌 Tweezers with thin ends - for working with plumes and small connectors.

Also, make sure that the workspace is well lit, free of dust and static electricity. Use an antistatic bracelet if you have one, it will keep the motherboard from being damaged. Don't take your smartphone apart on a carpet or soft surface, screws and small parts are easily lost.

⚠️ Note: If you are disassembling a smartphone with a broken display, be sure to stick tape on it so that the glass shards do not get inside the case or hurt you. Also note that the Redmi Note 6 Pro has a glued battery design – its forced detachment without heating can lead to fire!

Removing the back cover: how not to damage the latches

The back cover of the Redmi Note 6 Pro is mounted on latches and double-sided tape, and to remove it, you need to carefully apply the lid around the perimeter, starting at the bottom edge (near the USB-C connector).

1. Turn off your smartphone and remove the tray for SIM-map.
2. Heat the back cover with a hair dryer (a temperature of ~60°C) for 1-2 minutes to soften the glue.
3. Insert a plastic mediator into the gap between the lid and the case at the USB-C connector.
4. Carefully drive the mediator along the edge, alternately snapping the mounts. Don't force it -- if the lid doesn't respond, warm it up again.

Pay special attention to the corners of the lid, where the most fragile latches are located. If you hear a crack, then one of them has broken. This is not critical for functionality, but can worsen the dust protection. Also make sure that dust or debris does not fall under the lid, later this can cause problems with the sensor or speakers.

After removing the cover, you will see:

• 🔋 Battery with connected connector.
• 📟 Motherboard with protective screen.
• 🎤 Lower microphone and speaker.
• 📶 Antenna contacts (do not touch them unnecessarily!).

⚠️ Warning: Don't touch the motherboard with your bare hands -- static electricity can disable the chips. If you've touched the board, wipe it with an alcohol tampon before assembly.

Battery shutdown: why it's critical

Before you continue disassembling, be sure to turn off the battery.This will prevent short circuits that could burn the board or damage the plumes. In the Redmi Note 6 Pro, the battery connector is located at the top of the board and closed with black insulation tape.

To disconnect the battery:

1. Carefully tuck the insulation tape with tweezers and remove it.
2. Pick up the battery connector with a plastic mediator (not metal!).
3. Unplug the plug by pulling it up (not to the side!).

If the connector is stuck and doesn't detach, don't use force. Try to heat it with a hair dryer (no more than 50°C) or drip isopropyl alcohol on the contacts. Never tear off the battery with meat - in the Redmi Note 6 Pro it is glued to a very strong glue, and this action can deform the body.

Removal of the motherboard: the order of disconnecting the plumes

The Redmi Note 6 Pro motherboard is attached to a midframe on 12 different size screws, and remember their location, because when you build the screws, you have to get in their place, otherwise you can damage the board.

Procedure for disconnecting the plumes:

1. Main camera plume (top left corner of board).
2. The plume of the touch glass (under the metal cover in the center).
3. Display plume (near the slot for SIM-map).
4. The fingerprint scanner plume (if it is in your modification).
5. Antenna cables (detached last).

To turn off the plumes, use plastic tweezers. Most connectors have latches that you have to lift before you remove the plume. If the plume doesn't come out, don't pull it by force, make sure you remember to open the latch.

💡

If the display plume breaks, don't panic: it can be replaced separately from the screen itself, but don't hurt the flexible part, or you'll have to change the entire display module.

After you turn off all the plumes, gently tuck the board with a plastic mediator and remove it. Don't pull the edges, you'd better grab hard sections (like near a USB-C connector). If the board sits tight, check if all the screws are unscrewed.

Replacement of the battery: nuances and alternative methods

The battery in the Redmi Note 6 Pro is one of the most vulnerable parts, and it swells up over time, loses capacity, or refuses to charge, and it takes extra care to replace the battery because of the strong adhesive layer that attaches it to the body.

There are three ways to extract the battery:

• 🔥 Heated with a hair dryer (up to) 60-70°C) + The risk of battery deformation is negative.
• 🧴 Isopropyl alcohol (90%+ concentration, softens the glue, minus: long drying.
• 🧲 Special suction cups for batteries (sold in repair kits.

If the battery is swelling, don't puncture it, it could cause a fire.

1. Put your smartphone in a tight package and leave it for 12-24 hours – it will reduce pressure.
2. Use a ceramic knife (not metal!) for neat tweaking.
3. If the glue does not lend itself, repeat the heating or add alcohol.

The new battery is installed on double-sided tape (usually included). Make sure the contacts are clean and not bent before gluing, and make sure that there is no debris or old glue left under the battery.

1. Correct connection of the board plume.

2. Integrity of contacts of the battery connector.

3. The presence of a short circuit (measure the multimeter voltage on the board).-->

Smartphone Builder: How to Avoid Mistakes

The Redmi Note 6 Pro should be assembled in reverse order, but with a few key points in mind:

• 🔩 Screws must fall into place – tangled screws can damage the board or body.
• 📶 Antenna cables shall not bend or touch metal parts.
• 🔋 The battery should lie flat, without distortions.
• 🧲 Magnetic elements (e.g., Hall sensor) should not come into contact with metal tools.

Before final assembly:

1. Check the operation of all buttons (power, volume).
2. Connect the charger and make sure that charging is underway.
3. Turn on your smartphone and test the sensor, cameras and speakers.

If something doesn’t work after assembly (for example, the sensor doesn’t react or there is no sound), take the smartphone apart again and check:

• Integrity of plumes (especially the display and cameras)
• The density of the antenna contacts.
• No debris under the buttons.

⚠️ Warning: If the smartphone overheats or discharges quickly after assembly, you probably forgot to connect one of the plumes or installed the battery incorrectly!

Frequent problems after disassembly and their solution

Even if you followed the instructions, after disassembling the Redmi Note 6 Pro, you may have problems, and here are the most common ones and how to fix them:

If the smartphone is turned on but is not running smoothly (e.g., spontaneously restarted), this may indicate:

• 🔌 Bad battery contact - check the connector.
• 📱 Damage to the board - inspect it for darkening or bloated capacitors.
• 🔥 Overheating the processor – apply a new heat paste.

If you can't fix the problem yourself, go to the service center, and save all the screws and parts, which will help the wizard diagnose the malfunction faster.
