How to disassemble Xiaomi Redmi 6: step-by-step instructions for repair

Smartphones of the Redmi line have long proven themselves as reliable devices, but even the highest quality equipment requires maintenance over time. The question of how to disassemble the Xiaomi Redmi 6 often arises for owners faced with a broken screen, a failed battery or the need to clean the speakers from dust. Self-dismantling the case allows you to save a significant amount on the services of the service center, if you act carefully and consistently.

The Xiaomi Redmi 6 disassembly process has its own design-related features. Unlike the flagship models with glass back covers, it uses a plastic monoblock, which makes it easier to do but requires caution when working with latches. The key is the right sequence of actions that will prevent damage to the plumes and plastic mounts.

Before you start, you need to prepare the workspace and tools, you need a set of precision screwdrivers, a plastic spatula (mediator) and, preferably, a suction cup to lift the lid. Remember to turn the device off completely before you start any manipulations, as working with electronics under voltage can lead to a short circuit.

Workplace preparation and necessary tools

Quality preparation is key to successful repairs. You don't need complex industrial equipment to disassemble the Redmi 6, but using the wrong tools can lead to scratches on the body or screws breaking. The main tool will be a PH00 or PH000 size cross screwdriver.

It is important to ensure good lighting of the work area. Small parts, such as the motherboard mount screws, are easy to lose on the table if the light falls incorrectly. It is recommended to use a magnetic mat or container with cells to sort the fastener by disassembly steps.

The list of equipment required includes:

  • ๐Ÿ”ง Set of screwdrivers (cross and flat)
  • ๐Ÿ›  Plastic shoulder blade or mediator
  • ๐Ÿ“ฆ dielectric-coated tweezers
  • ๐Ÿ”ฅ A hair dryer or thermophene (to soften glue)

โš ๏ธ Note: Using a metal knife instead of a plastic blade when opening the case can damage the antenna module soldered into the plastic cover, which will lead to a deterioration in signal reception.

Pay special attention to clean hands and tools. Fat spots can remain on the internal components, and static electricity can harm sensitive electronics. Before you start disassembling the Xiaomi Redmi 6, it is recommended to remove static bracelets or simply touch a grounded metal object.

Removal of the back cover and primary dismantling

The first step is always to remove the back panel. In the Redmi 6, it is attached to a two-part glue and plastic latches around the perimeter, and first you need to twist two screws located at the bottom of the body, next to the charging connector.

Once the screws are removed, you need to warm up the perimeter of the back cover. Use a hair dryer at about 80-90 degrees, and warm the edges evenly for 2-3 minutes. This will soften the adhesive layer, making the opening process easier.

Follow the algorithm further:

  • ๐Ÿ“ฑ Apply the suction cup to the bottom of the back cover.
  • ๐Ÿ”ผ Carefully pull the suction cup upwards, creating a gap between the case and the lid.
  • ๐Ÿช“ Insert a plastic spatula into the resulting gap.
  • ๐Ÿ”„ Swipe the shoulder blade along all sides, snapping the locks.

If the back cover does not lend itself, do not use excessive force. Reheat the problem area with a hairdryer to avoid cracks on the plastic.

When the lid is removed, you see the inside of the smartphone, and immediately disconnect the fingerprint scanner plume if it's glued to the lid, so it doesn't damage it if you manipulate it further, and the battery and the basic components are now available.

Access to and replacement of the battery

Replacing the battery is one of the most common reasons for disassembling a smartphone. In Xiaomi Redmi 6, the battery is closed with a plastic frame, which acts as an additional structural amplifier. To access the battery, you need to unscrew all the visible screws that attach this frame.

Note that some screws may be hidden under decorative stickers or under the camera module. Carefully inspect the board before you apply the effort. Once the frame is removed, the battery plume is accessed.

The replacement process is as follows:

  • ๐Ÿ”‹ Disconnect the battery connector from the motherboard.
  • ๐Ÿงด Drop a little alcohol or a special solvent under the battery.
  • โณ Wait. 2-3 minutia.
  • ๐ŸŽฃ Carefully tuck the battery with a plastic card or spatula.

โš ๏ธ Warning: It is strictly forbidden to pierce or bend a lithium-ion battery. Damage to the shell can lead to fire or chemical burns.

When installing a new battery, make sure that the contact area is clean. If the old glue remains on the case, it must be removed. Use special adhesive tapes or double-sided electronics tapes to securely fix the new battery.

Replacement of the display and touch screen

Disassembling the front of the replacement device requires the utmost care, the display module in Redmi 6 is glued to the frame, and the plumes pass under the motherboard, which complicates the process, as it often requires partial removal of the motherboard.

First, you have to remove the metal shield covering the connectors of the display, which is mounted with multiple screws of different sizes, and remember or photograph the location of each screw, as their length may vary.

The main stages of work with the display:

  • ๐Ÿ“ธ Take a photo of the location of the screws before removing.
  • ๐Ÿ”Œ Disconnect the display and touchscreen plumes.
  • ๐ŸŒก๏ธ Warm up the screen perimeter to remove old glue.
  • ๐Ÿงน Carefully clean the frame of the adhesive residue before installing the new module.

โ˜‘๏ธ Pre-assembly check

Done: 0 / 4

The new screen should be checked for performance before the final sticking, plug the plumes, turn on the phone and make sure the image and sensor work correctly, only after a successful test apply a new B-7000 glue or use a factory adhesive base.

Working with motherboard and modules

Completely disassembling a smartphone is impossible without removing the motherboard. This is necessary to replace the charging connector, microphone or speaker, which are often soldered on the board or connected through complex plumes. In Redmi 6, the board is quite compact and sits tightly in the case.

Before removing the board, be sure to remove all the interference elements: the camera, speaker, vibrator. The camera plume often runs over or under the board, requiring careful withdrawal. Don't pull the plumes sharply - they are very fragile.

Table of the main modules and their location:

Maternity feeUpper partScrews + latchesRequires 5+ shutdowns of plumes
Charging chargesThe bottom partScrews.Linked by a plume to the main board
Main camera.Upper cornerGlue + connectorFragile lens
DynamicianLower cornerScrews.It has a rubber sealer.

When working with the motherboard, avoid touching the contacts with your fingers. Oxidation or moisture can cause the device to fail. If you change the charging connector, make sure the new connector is fully compatible with the revision of your board.

Assembly of the device and verification of functionality

The Xiaomi Redmi 6 is built in reverse order, but requires attention to detail. The main difficulty is the correct positioning of the plumes and the absence of unnecessary screws. Don't twist the screws to the point at once - first make all the mounts, then evenly tighten them.

Pay special attention to the adhesive of the case. Apply a thin layer of glue around the perimeter, avoiding getting inside the optics of the cameras or speakers. After connecting the parts of the case, it is advisable to fix the smartphone with rubber harnesses for 15-20 minutes to polymerize the adhesive.

Final checklist:

  • ๐Ÿ“ถ Checking the operation of all communication modules (Wi-Fi, GSM, GPS).
  • ๐Ÿ”Š Testing sound through speaker and conversational speaker.
  • ๐Ÿ“ท Checking camera and flash.
  • ๐Ÿ”‹ Control of the charging process and the operation of the sensor.

๐Ÿ’ก

Quality assembly is determined not only by appearance, but also by the absence of backlashes and creaks when compressing the body in the hand.

If the phone doesn't turn on after assembly, don't panic. Check the battery plume and the power connector. Often the problem is an incomplete plug or a forgotten screw that closes the contacts.

Frequent errors and expert recommendations

Beginners often make mistakes that can turn simple repairs into a difficult problem. One of the most common is the use of force where heat or a thinner tool is needed. Redmi 6 plastic is flexible enough, but at low temperatures becomes brittle.

Another mistake is ignoring the marking of the screws, which uses screws of different lengths, and if you screw a long screw into a short hole, you can punch through the body or damage the inner paths of the board, which will lead to irreversible consequences.

Advice to avoid problems:

  • ๐Ÿšซ Do not heat the device for more than 5 minutes in a row, so as not to damage OLED-The matrix (although in this model) IPS, Overheating is still harmful to glue).
  • ๐Ÿ” Use a magnifier or macro shot of your phone to inspect small details.
  • ๐Ÿงผ Degrease surfaces before gluing for better adhesion.

โš ๏ธ Warning: If you smell burning or see smoke when you first turn on after repair, turn off the battery immediately.

Technology and accuracy are your main tools. A properly disassembled and assembled Redmi 6 will last a long time, enjoying stable operation. Don't be afraid to study the device, but always evaluate your strength before you start work.
