How to disassemble Xiaomi Redmi Note 6 Pro: a step-by-step guide

Modern smartphones, including popular models from Xiaomi, are becoming more difficult to maintain, but this does not mean that self-repair is impossible. Disassembly Xiaomi Redmi Note 6 Pro may be required to replace a broken display, failed battery or restore the charging socket.

However, before starting dismantling, you need to be clear about the structure of the device and the risks: depressurization of the case automatically deprives the user of the warranty if it was still in effect at the time of the breakdown, the internal layout of this device requires care, since many elements are attached to glue and require careful handling of heating devices.

This guide is designed for those who are willing to act in a cold and consistent manner. Redmi Note 6 Pro has a glass back cover, which imposes additional restrictions on opening methods compared to plastic counterparts. Proper preparation of the workplace and the availability of specialized tools is the key to successful completion of the operation without damaging the motherboard.

Required tools and workplace preparation

The way you disassemble any electronic device starts with a space organization, you need a large table with good lighting, where there's no stopping the parts from being put in a certain order, and the chaos in the workplace often leads to the loss of microscopic screws or the entanglement of plumes of the same length.

The Redmi Note 6 Pro will require a specific toolkit that goes beyond a typical screwdriver, and the glass in the back is glued around the perimeter, so mechanical action without preheating will destroy it, and ignoring this step makes further repairs economically inefficient.

โš ๏ธ Warning: Using an open fire or a building hair dryer at maximum power can cause the battery to overheat and ignite.Control the heating temperature of the back cover by touching it with your finger - it should be hot but tolerant to the skin.

Gather the following arsenal before starting work:

  • ๐Ÿ”ง A set of precision screwdrivers (cross-haul) PH000, PH00 flat).
  • ๐Ÿ’จ Hair dryer or hot water heater for softening glue (temperature) 80-100ยฐC).
  • ๐Ÿ’ณ Plastic cards or mediators for opening the body.
  • ๐Ÿงฒ Magnetic mat or organizer for screws of different sizes.
  • ๐Ÿงค Antistatic gloves and tweezers with dielectric tips.

Pay special attention to mediators and plastic blades. Metal tools can damage internal plumes or shorten contacts on the board if you do not take extreme care. Plastic is safer in this regard, although it requires a little more effort to unplug the latches.

Rear panel removal and primary access

The first step in the process of disassembling the Xiaomi Redmi Note 6 Pro is to turn off the device. Even if the screen does not respond, you need to hold the power button until the indicators are completely damped. Working with the motherboard on increases the risk of short circuit when the plumes are disconnected.

Remove the tray for SIM-This is a standard procedure that is often overlooked by beginners, but a forgotten card can crack when heated or damage the slot when retrieved carelessly.

Heat the back glass panel evenly around the perimeter. The glue that holds the glass melts at about 80 degrees Celsius. Don't hold the hair dryer at one point for too long to avoid local overheating of the matrix or battery. The heating process usually takes 2 to 4 minutes depending on the power of the appliance.

After heating, insert a suction cup at the bottom of the back cover, pull it back, and insert a thin plastic map into the gap, drive the map along the perimeter, cutting the glue layer, move slowly, feeling resistance: if the cardboard is tight, add a little more heat.

It is important not to damage the fingerprint scanner, which is integrated into the back cover and connected to the board with a thin plume, and a sharp jerking motion can cause this connection to break, which will require replacing the entire module of the cover assembly.

What to do if the back cover is broken?
If there are cracks in the glass during heating or opening, don't try to push harder. Put a wide tape or paint tape cross over, which will prevent the shrapnel from falling inside the case and allow the glass residue to be carefully removed without damaging the internal components.

Removing protective screens and disabling plumes

When you successfully remove the back cover, you'll see the interior of the smartphone, and most of the space is occupied by a battery, and there are protective metal plates in the top and bottom, and these plates are screwed with many screws of different sizes and types.

You have to unscrew all the visible screws on the metal screens that cover the connectors. The Redmi Note 6 Pro uses a lot of fasteners, and they can vary in length. A reverse build error where a long screw is screwed into the hole for a short one can cause the board to break.

Remove the metal bar covering the top of the motherboard, and underneath it are the main connectors: the display module, the main camera plume, and the control board plume, and carefully disconnect each one using a plastic blade or nail, putting the connector upwards.

Don't pull the plumes themselves! Connectors are fragile elements, and applying force to a flexible cable will cause it to break, and the movement should be aimed at breaking the connector itself from the reciprocating part on the board.

Once all the plumes are turned off, you can remove the motherboard, which can be fixed with additional screws on the sides or held on a tight landing, and raise the board carefully, making sure that you do not catch the tail of the side buttons or the antenna wire.

When unscrewing the screws from the metal screens immediately screw them back into your holes on the removed plate, this will help not confuse which screw from where, and save them from loss.

Replacement of the battery and work with adhesive joints

The battery in the Xiaomi Redmi Note 6 Pro is centrally positioned and glued to the frame with double-sided tape. The adhesion force can increase over time, making battery extraction a difficult task. Never use metal objects to tamper with the battery.

To extract the power source, it is recommended to use a special hood with suction cups or, in extreme cases, a plastic card and isopropyl alcohol. Drip a few drops of alcohol under the edge of the battery and wait a couple of minutes: the liquid will dissolve the glue, facilitating slipping.

If the battery is swelling, you need to work with extreme caution. The mechanical puncture of the lithium-polymer battery causes an instant chemical reaction with the release of caustic smoke and fire. If you detect bloating, do not try to insert the card deep under the battery.

Once the old battery is removed, clear the seat of glue residues. The new battery must be installed on fresh bilateral tape. Using old glue or not will cause the battery to shift when it is running and may damage the plumes.

โš ๏ธ Warning: If you smell a specific sweetish smell or see smoke from the battery, stop working immediately, get out into the fresh air and place the element in a non-combustible container with sand.

Connecting the new battery is only made after installing all the protective screens and checking the absence of foreign objects on the board. It is better to start the initial start by connecting the charger to exclude voltage surges.

Dismantling of the display module and glass replacement

Replacing the display with the Redmi Note 6 Pro is one of the most common reasons for disassembly. The screen here is not only attached to the perimeter, but also has additional fixing points in the center of the frame.

First, you need to remove the old frame with the broken screen, and heat the front of the device. Be careful: the heating in the front is more dangerous, because under the glass is a matrix that can leak or stain from high temperature.

Use a thin string or line to cut the glue under the matrix. The movements should be sawing, without jerking. If you plan to change only the glass (glass panel) and not the module assembled, you will need a separator and an ultraviolet lamp for professional gluing.

In the home, it's easier and more reliable to replace a framed module, so you don't have to clean tons of glue and you don't have to damage the thin OLED or IPS matrix when you separate, and you just put the new module in place of the old one and plug in.

Touchscreen and image performance are checked before the final body glue is done, make sure there are no dead zones and no color spots, and only after a successful test can you apply new glue and fix the structure.

Device assembly and final inspection

The Xiaomi Redmi Note 6 Pro is assembled in reverse disassembly. Set the motherboard, make sure all the racks are in their holes. Roll all the screens and connectors, checking the reliability of the plumes.

Apply a new B-7000 glue or a special adhesive layer to the body frame. Don't overdo it with the amount of glue, otherwise the excess glue can squeeze out or get inside the camera optics. Spread the layer evenly around the perimeter.

Set the back cover and press it tightly around the edges. For a secure fix, it is recommended to use rubber straps or a load for 15-20 minutes until the glue is grasped. Complete polymerization of the adhesive takes about 24 hours.

Once assembled, turn the device on and run a comprehensive test: check the cameras, speakers, microphones, Wi-Fi module and fingerprint sensor, if all functions work correctly, disassembly and repair can be considered successful.

The quality of the repair depends on the cleanliness of the work and the absence of dust between the layers of the display and the body.

Do I need to completely drain the battery before replacing it?
No, the lithium polymer batteries used in Xiaomi don't have memory effects, and deep discharge is bad, and the optimal charge for storage and replacement is about 40-60%.
How to replace the B-7000 glue if it is not available?
Alternatively, you can use adhesives like the T-7000 (black, less visible) or special adhesive strips that are cut into the shape of the body, which is absolutely not used, because it destroys plastic and glass.
What if the phone does not turn on after assembly?
Check the connection of the display plume and battery, often the connector does not fully stand up, and also make sure that the screws of the metal screens do not pass the plumes below.
Can I warm my phone with a hair dryer?
A normal hair dryer develops the temperature to 60-70 It takes a long time to heat up, which is dangerous for the battery. It's better to use a temperature-adjusted building dryer.
