Xiaomi Redmi Go: how to disassemble a smartphone for repair

Modern budget smartphones like the Xiaomi Redmi Go often require hardware intervention after a fall, moisture or simply because of the natural wear of the battery. Unlike flagship models with glued structures, this gadget has a removable rear panel, which greatly simplifies initial access to internal components. However, full disassembly of the device for replacing the screen or repairing the board requires accuracy and understanding of the design.

Before you start dismantling, you need to prepare a workspace with good lighting and antistatic coating. Power outage is the first and most important step that will keep electronics from shorting during operation. Even if the phone is off, the battery can supply current to the circuit, so safety is a priority.

In this article, we will take a closer look at the process of dismantling the Redmi Go, paying attention to hidden screws and fragile plumes. You will learn what tools will be required for the job and how to avoid common errors that can lead to a failure of the case or matrix.

Tools and workplace preparation required

A screwdriver is not enough to disassemble a smartphone properly, and you will need a specialized toolkit that allows you to work with small screws and plastic latches without the risk of damage, the main tool being a PH00 or PH0 cross screwdriver, as these are the screws used in Xiaomi’s design.

A mediator, a plastic blade or a special tool for opening the case is ideal for working with plastic elements, and the use of metal objects such as a knife or needle is highly undesirable, as this can lead to scratches or breakage of the insulation.

🔧 Precision screwdriver set (PH00, PH0, flat-footed 1.5 mm).
🛠️ Plastic blades (spudger) and a mediator for opening the body.
🌡️ Dryer or heat pad to soften glue (if the battery is glued).
🧲 Magnetic mat or organizer for screws.
🔦 A bright light source for illuminating internal components.

⚠️ Note: Before starting the work, be sure to remove SIM-microSD card and memory card: Attempting to disassemble a phone with installed cards can cause slots to break or damage the drives themselves.

Space organization also plays a role: spread out the screws in order of their extraction, so that when assembled, you don't confuse the dimensions. Some screws can be of different lengths, and putting a long screw in a short hole can damage the board.

Removal of the back cover and primary access

Xiaomi Redmi Go has a removable back cover, which is rare for modern smartphones and makes it much easier to access the battery. First, turn the device down and find a small notch in the bottom corner of the end. This is the notch that you need to insert a nail or a plastic blade.

Carefully pull the lid upwards with a uniform force. You should not use excessive force, because plastic can crack if the latches do not immediately respond, you can slightly tweak the edge with a shoulder blade and run it along the perimeter, snapping the locks.

And when you take the lid off, you'll see the inside of the smartphone, and you'll see the battery pack, the slots for the device. SIM-At this stage, you can already replace the battery or memory card, but access to the motherboard will require further disassembly.

Note the sticker with model and IMEI information, which often closes screws or is part of the design.Warranty seals, if present, will be broken when the lid is removed, which is important to consider if the device is still warranty.

📊 Did you need to know about Redmi Go?

Yeah, I changed the battery.

Yeah, I broke the screen.

No, just curious.

I'm planning a renovation in the future.

Dismantling the protective framework and motherboard

To access the main board, remove the black plastic screen frame that covers the top of the device, which is fixed by several screws around the perimeter and possibly additional mounts in the center, and carefully examine the surface for hidden screws under the stickers.

Use a PH00 screwdriver to unscrew all the visible screws. The number can vary, but usually there are about 10-12 pieces. After removing the fastener, gently tuck the frame with a plastic blade, starting at the bottom or side edge.

It's important to be slow, because you can have button plumes or antenna contacts on the frame, and if you pull the slug, you can break the thin conductors, and when you remove the frame, you can access the motherboard, the cameras, the connectors.

📱 Carefully disconnect the main camera plume if it interferes with access.
🔌 Check the location of Wi-Fi antenna contacts and GSM, so as not to harm them.
🔋 Make sure the battery connector is not damaged when manipulating the frame.

The motherboard in Redmi Go is secure enough to turn off all the plumes that go to the display, cameras and sub-board before removing it, and the connectors should be snapped with a nail or a plastic blade, avoiding pressure on the board itself.

Replacement of the battery and work with the battery

In the Xiaomi Redmi Go model, the battery is a removable element, but in some revisions it can be planted on double-sided tape for fixation.If the battery is held loose, just remove it by pulling a special tongue or notch.

If the battery is glued, it needs to be carefully separated, so you can use a suction cup to lift the edge, and then, inserting a plastic card or a shoulder blade, cut off the adhesive layer. Never use metal tools to unstick the battery, because a puncture of a lithium-ion cell can cause fire.

What to do if the battery is blown?

If you notice that the battery is bloated and takes up more space in the case, do not press it or try to pierce it. Remove it as carefully as possible using only plastic tools, and immediately dispose of it at a special reception point.> When installing a new battery, make sure that the contact group on the battery itself and the return connector in the phone are clean. If necessary, wipe the contacts with alcohol.

The display module here is attached to a metal frame (middle) on the glue. To remove it, you first need to completely dismantle all the internal components described in the previous sections. After removing the board and battery, the "skeleton" of the phone with the glued screen remains. It requires heating to remove it. Use a hair dryer to warm the screen to a temperature around 80-90 You need to heat it evenly, not lingering long at one point, so as not to damage the matrix. ⚠️ Attention: Don't overheat the screen! Excessive heating can cause yellow spots on the matrix or polarization layer to detach. Keep the hair dryer at a distance 3-5 After warming up, use a suction cup and a thin line or a special string to cut the adhesive layer around the perimeter. After separation of the glass from the frame, clean the remains of the glue with alcohol or a special solvent. ☑️ Check before assembly Checking the touch screen Checking the image Checking the speakers Final assembly Completed: 0 / 4 The assembly is done in reverse order, first a new display module is installed on glue or double-sided tape, then all the internal components are returned to place: the motherboard, cameras, plumes and speaker. Pay special attention to the correct positioning of the plumes - they must enter before the characteristic click. When installing the frame screen, make sure that all screws are screwed into their places. And if you put a brace on it, you can split the plastic, and if you don't twist the screw, you can actually pull the plug on the structure, and then you can put the battery in and plug in the power plume, and you can try to turn it on. If the screen catches fire, the sensor is working, the sound is working, the assembly was successful, the back cover is better not to snap completely so that you can quickly disassemble the phone in case of problems. 🔍 Visually check for no extra parts or screws. 📡 Check the operation of communication modules (Wi-Fi, Bluetooth, GSM). 🔊 Make sure the talking and polyphonic speakers don't wheez. The final step is to install the back cover. Match the protrusions at the top of the cover with the grooves of the body, then press the perimeter until the locks are snapped. A characteristic click on the entire circuit indicates the correct installation. Frequent disassembly problems and their solution During the repair process, users often face difficulties that seem insurmountable without experience. One of the common problems is a break of the plume with careless removal. If the plume is torn at the connector itself, you can try to restore it with conductive varnish, but it is more reliable to replace the entire component. Another problem is the loss of screws. Small screws are easily lost in the pile of the carpet or fall into the slots. Using a magnetic mat or spreading screws on a sheet of paper with a drawn circuit will help avoid chaos during assembly. Also, a scenario is possible when the phone does not turn on after assembly. Most often this means that the battery plume or display is not fully inserted into the connector. You need to disassemble the device again and re-soften it to use the screen without re-refrigulate it to re-up the device, however, can it be used to re-refrigerate it to re-refrigulate it to re-react the display it to re-up the device, if it is used to re-refrigerate it to re-refrigerate it to re-refrigerate it to re-refrigerate it, if it, to re-refrigerate it It is best to use a special glue. B-7000 or T-7000. They have optimal elasticity and strength, and allow you to disassemble the device again if necessary. Will the warranty break after disassembly? Yes, the Xiaomi Redmi Go self-disassembly and violation of warranty seals automatically remove the device from warranty service. If you have a warranty, you should go to an authorized service. Where to buy original parts? Original parts can be found at Xiaomi authorized service centers or official distributors. There are also many quality analogues on the market that can cost less. 💡The key to a successful showdown is patience and lack of haste. Every movement must be conscious, and force must be applied only when you are confident in the design.
