Disassembly of the Xiaomi Redmi Go smartphone can be required in various situations, from the banal replacement of broken glass to the installation of a new battery. This device has a relatively simple design, but like any modern electronics, requires careful handling. Before starting work, it is important to understand that opening the case automatically deprives you of an official warranty if it was still valid.
The dismantling process starts with an assessment of the condition of the externals. The back cover in this model is made of plastic and attached to adhesive, which is the standard for the budget segment. You will need not only a set of tools, but also patience to avoid damaging the fragile plumes that connect the main modules. In this article, we will discuss each step in detail to minimize the risk of failure.
Take your time in the first step. In the opening phase, errors often cause damage to internal components that are difficult or expensive to repair. The main board in Redmi Go is located at the bottom of the case under the protective screen, which requires special attention when working with screws. Next, we will move on to the preparation of the workplace and the necessary tools.
Preparation of the workplace and tools
You can't do a good job of disassembling without a properly organized space. You'll need a table with good lighting to see the small screws and connectors. The lack of bright light will cause you to lose tiny parts or damage the board with careless movement.
To work with Xiaomi Redmi Go, you will need a specific set of tools: Do not try to use kitchen knives or sewing needles, as they can break inside the case or damage plastic. The optimal choice is a professional or semi-professional suite for repairing mobile equipment.
- 🔧 Set of screwdrivers: mandatory presence of cross PH000 and PH00, Because the screws in this model are of this size.
- 🎴 Plastic spatula (mediator): necessary for snapping the body without scratching and damage.
- 🌡️ Hair dryer or heating pad: required to soften the glue under the back cover before removing it.
- 🧲 Magnetic mat or container: to avoid losing screws of different sizes in the process.
Pay special attention to the mediator. It should be thin enough to fit into, but not sharp enough to cut through the insulation of the plumes. The use of metal tools at this stage is strictly prohibited, as there is a high risk of short circuit or mechanical damage to the elements on the board.
Before you start physically affecting your phone, make sure it's off. Even if the screen isn't responding, try holding the power button for a while. 10-15 Working with the device on may cause the contacts to close when the plumes are disconnected.
Rear cover removal and primary access
The first step in the disassembly process is to remove the back panel, and unlike the flagship glass-backed models, it uses plastic that is more flexible but also more adhesive, and heating is a key part of this.
Use a hair dryer to warm up the body perimeter. Movements should be uniform, do not hold the flow of hot air at one point for longer than 2-3 seconds, so as not to melt the plastic or damage the display on the back. The temperature should be palpable to the hand, but not burning.
💡
Warm up the body around the perimeter with circular movements, paying special attention to the corners where the glue is usually the most.
After warming up, insert a plastic blade at the junction between the frame and the lid. Move the tool along the perimeter, gradually cutting the adhesive layer. Don't try to slam the lid off one edge and rip it off abruptly, which will break the plastic latches.
- 🔥 Heat: Heat the edges evenly during the course 2-3 minute 60-70 degree.
- 🔪 Opening: insert the mediator into the gap and lead it parallel to the plane of the screen.
- 👐 Fixing: Hold the body with your fingers so that it does not slip out during the separation of the lid.
When the lid is completely detached, don't be too quick to put it down. It can be connected to the main board with a thin plume of the fingerprint scanner (if the model supports), or just lie on the components. In the case of the Redmi Go, the lid is simply removed, but underneath it you will see a protective plate covering the screws.
Removal of protective plates and access to the battery
And underneath the back cover, there's a metal plate or a plastic plate that covers most of the components, and it's mounted on multiple screws of different sizes, and it's important to have the order of how you twist them, so you can put them back in the right way.
Use a magnetic mat to sort screws. The screws holding the board may be different in length from those that hold the bottom plastic lining. If you confuse them, you can damage the thread or punch the board with a too long screw.
☑️ Preparation for charge-off
When you remove the top protective plate, you get access to the battery socket, which is critical, and before you touch any other plumes, you need to turn off the power, find the battery connector, and gently put a plastic blade on it.
Be careful with the display plume. It's next to the battery connector and often has a lock. A sudden movement can break the contacts, which will require replacing the entire display module. If you see a metal bracket above the plume, it needs to be bent beforehand.
Replacement of the battery and work with plumes
The battery in Xiaomi Redmi Go is glued to the inside of the case firmly enough. To remove it, you will need to use heating or special solvents again. Do not try to pull the battery out by force, putting a screwdriver on it - this can cause puncture and fire.
Use a thin line or a special string to cut the glue under the battery. The movements should be sawing, without sudden jerks. After separation, carefully remove the power element, trying not to damage the surrounding components.
| Component | Type of attachment | Risks in dismantling |
|---|---|---|
| Back cover. | Glue + latches | Plastic cracks, latch breakage |
| Battery | Double-sided scotch | Puncture of the hull, deformation |
| Payment | Screws + plumes | Contact break, static tension |
| Display. | Frame + glue | Matrix break, cracks |
When installing a new battery, make sure that the contact pad is clean. If there are glue pieces left on the old battery, they must be carefully removed without touching the battery cell itself.
Connecting plumes requires precision. Combine the connectors before clicking, but without undue effort. If the connector doesn't fit in the first time, check orientation -- you may be trying to insert it upside down.
Extraction of motherboard
To fully remove the motherboard, all remaining modules must be disconnected, which includes the main camera module, flash, lower speaker and antenna contacts. Antenna contacts are often spring-loaded pins that need to be gently squeezed.
Unscrew all the circuit board screws. There could be 4 to 6. After that, the board can still be held on the plume of the lower speaker or vibrator. Carefully inspect the board perimeter for hidden connections.
Features of antenna contacts
Carefully raise the board from one edge, checking if nothing is disturbing. If you feel resistance, stop and check the connections again. Pull the board smoothly, without skewing, so as not to break the ceramic elements or connectors.
Once the board is removed, inspect it for oxides or damage. Often charging or sound problems are solved by cleaning the contacts with alcohol, without completely replacing the components. Use a soft brush and isopropyl alcohol for cleaning.
Assembly of the device and verification of functionality
The assembly is done in reverse disassembly. Start by installing the board and connecting the plumes. Make sure all connectors are snapped to the end. Then install the protective plates and twist the screws.
Before the final sticker on the back cover, it is recommended that you do an initial check: plug the battery, press the power button and make sure the phone responds, the MI logo appears and the sensor is working, which will save you time if you make a mistake somewhere.
⚠️ Warning: Do not turn on your phone if the back cover is not yet installed and you are working near metal objects.
Use a special glue B-7000 or T-7000 to fix the back cover. Apply a thin strip around the perimeter, press the lid and lock the device with rubber bands for 15-20 minutes. Remove the excess glue immediately until they freeze.
Once assembled, check all the functions: speakers, microphone, cameras, Wi-Fi and Bluetooth. If everything works correctly, the process can be considered complete. If there are problems, you will have to re-disassemble the device to find a malfunction.
