How to open the lid Xiaomi: full instructions for disassembly

Owners of Xiaomi smartphones and tablets sooner or later face the need to access the interior space of the device. Most often the question of how to open the Xiaomi cover arises when replacing the device. SIM-Modern gadgets of this brand, such as Xiaomi Redmi Note or flagship Xiaomi Mi, often have a monolithic body, which requires special approach and accuracy. Incorrect actions can lead to damage to plumes or leakage.

Before you start physically affecting the body, it is important to clearly define the type of design of your device. In the company's product line, there are both models with removable rear panels and devices with a non-shatterable body, where access to the inside is only possible through the display module or by unplugging the rear cover. Ignoring the design type is a direct way to break the mounts. In this article, we will analyze all possible scenarios in detail and provide an algorithm for safe opening.

Determination of shell design type

The first step before any manipulation is to identify the model and the type of its build. Most modern Xiaomi smartphones belong to the Unibody class, where the back cover is a non-removable element of the structure and is glued around the perimeter. However, in the budget segment, for example, in some versions of Redmi or Poco, there are still models with a plastic cover that is removed by hand.

To determine the type of case, carefully examine the ends of the device. If you do not see visible joints or micro-gaps around the perimeter, other than the junction line of the screen and the frame, you probably have a monoblock. SIM-card: if the tray is combined (SIM + microSD, there's no memory slot inside under the lid, and it doesn't make sense to open the device to expand the memory.

It's important to understand that even if the lid looks removable, it can be fixed with screws under decorative plugs. In older models like the Xiaomi Redmi 3 or Redmi 4X, the lid was removed easily, but in newer revisions, manufacturers often add locking screws. So the "find gap - fake" algorithm does not work here. You need to check the technical documentation or visual guides for a particular model.

⚠️ Warning: If you feel strong resistance when trying to remove the back panel, stop immediately. Chances are your model has a monolithic body, and further effort will lead to cracks in the glass or break plastic latches.

Essential tools for autopsy

High-quality disassembly is impossible without the right tools. Use of improvised tools such as knives, scissors or sharp needles is strongly discouraged, as they can damage internal components or accidentally puncture the battery. To safely open the case Xiaomi you will need a specialized set of tools that can be purchased in electronics stores.

The main tool is a plastic spatula or mediator. Plastic does not conduct current and does not scratch the surface as much as metal. To work with screws you will need screwdrivers with various nozzles, most often in the format of Phillips (cross) and sometimes Torx (star), although in Xiaomi smartphones the latter are less common. Also, you can not do without a suction cup, which will help create an initial gap between the screen and the case or between the back cover and the frame.

The adhesive base that holds the lids in monolithic models requires a heat source. Usually a household hair dryer or professional thermophen (preheated), as well as isopropyl alcohol to dissolve the adhesive. Be sure to prepare a screw folding container, as they can be of different lengths and the loss of a small screw can stop the assembly.

• 🛠️ Plastic blades and mediators for snapping latches without damage.
• 🔧 Set of screwdrivers (cross-crosses) PH000, PH00) screw-up.
• 💨 Suction cup to create an initial gap and safely lift panels.
• 🌡️ A hair dryer or thermophene for softening the adhesive layer around the perimeter of the housing.

How to open the tray for SIM-map

The simplest and safest type of "opening" available to any user is the extraction of the tray for the use of the device. SIM-This process does not require disassembly of the case and does not violate the warranty. There is a small hole on the end of the device, usually at the bottom or side, and a special metal clip that comes with the kit or a similar thin object is used to extract the tray.

Insert the tool perpendicularly into the hole and press until the characteristic click. The spring mechanism will push the tray out. SIM-The pressure on the microphone can damage its membrane. The tray in Xiaomi models often has a specific shape, allowing you to install microSD and nano-SIM cards in various combinations.

If the tray is not removed, don't use excessive force. Make sure you press strictly perpendicular. In some cases, especially in protected models or when dust hits, the mechanism may jam. In this situation, you can try to gently sway the paper clip, but without jerking. Damage to the extraction mechanism will require dismantling the phone for repair.

💡

Before installing a new one SIM-Wipe your contacts with a soft dry cloth to improve connection and avoid network reading errors.

Disassembly of models with removable back cover

If your device is a removable back cover (often plastic in the budget segment), the opening process is as simple as possible: flip the phone down onto a soft surface. Find a special notch or recess in the bottom corner of the rear panel. This is where the manufacturer has designed the finger grab.

Put your nail or plastic blade on the corner of the lid and smoothly navigate along the perimeter. You should hear a series of clicks, which are plastic latches opening. Don't rush to pull the lid abruptly, as it can be connected to the plume of the antenna or fingerprint scanner (although in simple models this is rare). Once all the locks are snapped, the lid will easily be removed, opening access to the battery.

Inside, you'll see a battery that's usually removable, and you'll see a small pocket cutout at the bottom of the niche, and you can remove it with your nail, and you can remove it, and remember, even in these models, you can have screws that lock your motherboard under your battery, but you don't need to replace your SIM or memory card.

• 📱 Put the phone down on a soft cloth to avoid scratches.
• 👆 Find the notch for the finger in the lower corner of the back panel.
• 🔓 Smoothly tuck and run along the edges to snap the fixers.
• 🔋 Remove the battery by pulling a special ledge in the niche.

Opening of the monolithic body (Unibody)

With models where the back cover is glued (Xiaomi Mi series, Xiaomi 11/12/13, Redmi Note Pro), it's more complicated. It requires heating. Turn on the hair dryer and warm the perimeter of the back cover evenly for 2-3 minutes. Don't hold the hair dryer at one point too long so as not to damage the back screen matrix or overheat the battery. The temperature should be palpable to the hand, but not burning.

Once warmed up, use a suction cup to create a microscopic gap between the lid and the frame. Insert a plastic blade or mediator into this gap carefully. Start slowly with the tool along the edges, cutting the softened adhesive layer. The movements should be sliding, parallel to the plane of the phone. If you feel resistance, apply heating again.

Exercise special care in areas where the plumes are located. In some Xiaomi models, the plume of the fingerprint scanner or side button can go to the motherboard through the back cover. Sharply pulling the open cover, you risk tearing this plume. After passing the perimeter, gently lift the cover and check for connections.

⚠️ Note: When working with a hair dryer, do not direct hot air directly into the chamber or the speaker area, as this can lead to fogging of the lenses or deformation of the speaker membrane.

Replacement of battery and internal components

Once the lid is successfully removed, you have access to the insides. The monolithic Xiaomi battery is also often glued to the body. To safely remove it, you have a fishing line or a thin plastic card installed under the body. The movements must be sawing to separate the adhesive base from the body. Do not use metal objects to tamper with the battery!

Before you turn off the battery plume, make sure the device is off.The plume is connected to the motherboard via a connector that often has a metal plate on the screws. Unscrew the safety plate, bend the plume and disconnect the connector. Only then can the old battery be fully removed.

The new battery is installed in reverse order, preferably with a B-7000 adhesive layer or pre-cut adhesive strips to keep it secure in the case, and the phone is assembled in reverse order: plugging in the plumes, mounting the protective plates, putting the lid on.

💡

The main difficulty of opening monolithic Xiaomi is the adhesive layer and the fragility of glass covers, which require patience and careful heating.

Frequent errors and precautions

One of the most common mistakes is to ignore the device shutdown before starting work. Even if the phone is software-operated, there is still a voltage on the board. A short circuit with a metal tool can disable the power controller or other important nodes. Always work with utmost care and use only dielectric tools where possible.

Another mistake is the loss of screws of different sizes. In Xiaomi smartphones, the screws of the board mounts, speakers and covers can vary by only a millimeter in length. If you screw a long screw into a short hole, you can punch through the board, which will lead to irreversible damage. Sort the fastener as you disassemble using a magnetic mat or cells.

And people often forget about glue. Trying to build a phone without applying a new layer of glue or using tape will cause the lid to slug, and dust and moisture to get inside. Tightness is an important part of the design, and you can't neglect it. Use a quality glue that remains elastic after drying.

• 🚫 Never leave your phone on when working inside the case.
• 🔌 Be careful with plumes: they are very thin and easily torn.
• 🧹 Clean the surfaces of the old glue before applying a new layer.
• 🧲 Use the sorting of screws so as not to confuse them when assembly.
