How to open Xiaomi Redmi: disassembly of the case and reset the system

Smartphone owners often face physical or software access to the insides of the device. Disassembly of the case may be required to replace a broken display, battery or clean the speaker from dust. In other cases, the phrase “how to open” users mean logging into the engineering menu or resetting the settings to the factory.

Whatever you need, it's important to understand the risks. Xiaomi Redmi is a complex electronic device where every plume and screw matters. Wrong actions when opening the case can lead to a loss of warranty or a breakdown of the gadget. So we'll look at everything from software login methods to physical disassembly.

In this article, we will discuss in detail the algorithms for actions for different models of the Redmi Note and Redmi series, you will learn what tools will be needed to safely dismantle and how to avoid damaging fragile plumes, and will also discuss the issues of software unlocking if the device is locked with a forgotten password.

Tools and workplace preparation

Before you start physically interfering with the design of a smartphone, you need to organize a safe space. The work surface should be clean, well-lit and preferably not conduct static electricity. The ideal option would be an antistatic mat, but a regular wooden table will do.

For a high-quality disassembly, you will need a specialized set of tools, the use of knives or kitchen utensils is strongly discouraged, as this increases the risk of damage to internal components.

• 🔧 Precision screwdriver kit (cross-hatch) P2, P5) hull-screw.
• 🔪 Thin metal or plastic mediator for snapping latches.
• 🌡️ A hair dryer or heat belt to soften the glue holding the back cover.
• 🧲 Magnetic mat or organizer for sorting screws of different sizes.

⚠️ Warning: Before starting any work, be sure to turn off the device. Attempting to disconnect the plume of the display or battery when power is on can lead to a short circuit on the board.

Pay special attention to the heating of the case.The glue used in modern Xiaomi requires a certain temperature to soften, but overheating can damage OLED-The optimal heating temperature is the screen or battery. 80-90 degrees Celsius.

Software Methods: Entering Recovery Mode

Often, the "how to open" request is what users mean by entering Recovery mode, which is a system partition that allows you to reset, update your firmware, or clear your cache without loading your main operating system, and that's the first step if your phone isn't working properly.

To enter the standard recovery menu, most Redmi models use a button combination. You need to turn off your smartphone completely, then press the volume button and power button. Hold them until the Mi logo appears.

The menu uses volume buttons (up/down) and the power button to confirm the choice. If you see a menu in Chinese, select the item corresponding to English if available, or navigate by icons.

• 🔄 Reboot: Reboot the device in normal mode.
• 🗑️ Wipe Data: Complete data deletion and resetting.
• 🔌 Connect with MIAssistant: Mode for connecting to PC for firmware.

There's also a Fastboot mode that's used for deep flashing, which is a volume and power button that's pressed to enter, and the screen in this mode usually displays a hare repairing an android, or the Fastboot logo, and exits by holding the power button for a long time.

Physical disassembly: Removal of the back cover

Modern Xiaomi Redmi smartphones often have glass or plastic back panels glued around the perimeter.A mechanical opening without preparation will lead to cracks.Heat the edges of the device with a hairdryer for 2-3 minutes, evenly distributing heat.

After heating, insert the suction cup into the bottom of the back cover and pull up slightly to create a gap. Insert a thin mediator into the resulting gap carefully. Move the tool along the perimeter, feeling the resistance of the glue. Do not plunge the mediator deeper than 3-4 mm, so as not to damage the internal plumes.

Be especially careful in the area of the camera module and the fingerprint scanner. In some models, the scanner can be glued to the lid and connected to the motherboard with a thin plume. A sharp jerk can break the connection.

💡

Use plastic cards (such as old credit cards) cut into strips as additional mediators. They do not scratch the case and pass well under the lid.

Once all the latches are snapped, don't rush to remove the lid completely. Check for plumes connecting the lid to the main board. Most often, it's a tail of a side button or logo highlights. Disconnect them by putting your nail or plastic blade on the connector.

Access to battery and internal components

When you remove the back cover, you'll see an interior space that's covered by a plastic or metal plate, and it's attached to a lot of screws of different sizes, and you'll organize them so that you don't screw a long screw into a short hole when you build it.

Removing the protection, you will have access to the battery and plumes. The battery in Xiaomi smartphones is usually planted on double-sided tape. Use a special liquid (Isopropyl alcohol) to extract it or gently poke it with a plastic card, heating the surface with a hairdryer.

⚠️ Warning: Never puncturing the battery or bending it. Damage to the lithium polymer battery may cause ignition or explosion. If the battery is swelling, remove it with utmost care.

When you replace the display, you have to disconnect the plumes that are under the protective plate, they are fixed by metal clipping slats, unscrew the slat screws, remove them and carefully bend the plumes upwards. Remember, the first one disconnects the battery plume to de-energize the device before working with other components.

Unlocking a Forgotten Password and Account

If you meant "open" when you had a forgotten pattern lock, it's more complicated. Modern versions of MIUI and Android are highly protected. Simply removing the battery or flashing it through Recovery without resetting your account won't help.

There is a method of resetting through Recovery mode (Wipe Data), but it will delete all user data. Once reset, the device will request confirmation of the owner through a Google account or Mi Account that was synced earlier. FRP (Factory Reset Protection).

There are complex software methods that require PCs and specialized software to bypass FRP (such as Mi Flash Pro or test point tools), but the effectiveness of these methods depends on the Android version and security patch, and in most cases the legal way is to restore access through the manufacturer's website.

• 🔑 Try to recover your password through account.xiaomi.com.
• 📧 Use a backup email or phone number to reset.
• 🛠️ Contact the service center with a purchase check for proof of ownership.

Attempts to hack someone else’s device or use questionable paid unlock services can lead to a complete lock of the device by IMEI. Be vigilant and use only proven methods of access recovery.

💡

Resetting a password through Recovery deletes all data, but does not remove the lock of a Google or Mi Account if the device was previously tied.

Assembly of the device and verification of functionality

After the necessary manipulations (replace the screen, battery or cleaning), the assembly stage begins. It requires even more care than disassembly. Make sure that all the connectors of the plumes are snapped to the characteristic clicks. Unpressed display plume will lead to the absence of the image.

Apply a new layer of glue (B-7000 or special adhesive tapes) around the perimeter of the case before installing the back cover. Let the glue dry slightly (1-2 minutes), then tightly press the cover and lock the device with rubber bands for 15-20 minutes for polymerization.

The first time you turn on after assembly is critical. Don't rush to twist all the screws until you make sure the phone is on, responsive to the touchscreen, the speakers and the microphone are working. If everything is working properly, complete the assembly.

Check the proximity sensor and the fingerprint scanner. Sometimes after disassembly, you need to calibrate the sensors through the engineering menu, enter the code ##64663## in the call menu (if available), or use the Service app.
