Modern smartphones, including the popular Xiaomi Redmi Note 6 Pro, often fail due to mechanical damage to the body. Broken rear window is one of the most common reasons for contacting service centers, but you can replace it yourself with minimal skills. The dismantling process requires care, since the design of the device involves the use of adhesives around the perimeter of the body.
Before you start disassembling, you need to carefully prepare the workplace, you need a clean, well-lit desk so that the small screws and parts do not get lost, and it is important to understand that replacing the back cover is not just a mechanical action, but a procedure that requires attention to plumes and modules located in the immediate vicinity of the dismantling site.
In this article, we will take a detailed look at how to safely remove the lid, what tools are needed and how to avoid typical errors. Redmi Note 6 Pro has a specific mounting design where the main modules are located under the protective panel, so rushing here is unacceptable. Following the instructions will allow you to preserve the functionality of the device and avoid additional damage to internal components.
Tools and workplace preparation required
The quality of the work is directly dependent on the toolkit used. To dismantle the back of the Redmi Note 6 Pro, you will need not only a standard screwdriver, but also specialized devices to work with adhesive bases.
The main list of tools includes:
- ๐ง A set of precision screwdrivers (required the presence of a Torx bit) T5 or T6).
- ๐ฅ Hair dryer (building or household temperature-adjusted) for softening glue.
- ๐ช Thin metal scalpel or plastic blade to open the body.
- ๐งด Alcohol isopropyl or special solvent for glue.
- ๐ฆ New adhesive base (B-7000 framed).
You also need to make sure that the work surface does not conduct electric current, although the risk of short circuit when the device is turned off is minimal. Before starting work, be sure to turn off the smartphone and remove the tray. SIM-cards so as not to damage it during the heating process of the case.
โ ๏ธ Warning: Use of an open fire or too high a hair dryer temperature (above 100)ยฐC) may cause the battery to bloat or damage to the display on the back.
It takes no more than 10 minutes to prepare, but it makes it much easier to go on. Make sure that all the tools are on hand and you don't have to be distracted by finding them at the most critical time. Clean hands and tools are the key to keeping dust or grease out of the case.
The process of heating and separation of the rear panel
The key step in dismantling the Xiaomi Redmi Note 6 Pro is to properly soften the adhesive layer. Factory glue securely fixes the glass, and attempts to remove it without heating will lead to cracks. Heating should be done evenly throughout the perimeter of the device, paying special attention to the corners.
Direct the hot air flow to the back cover, holding the hair dryer at a distance of 3-5 cm from the surface. The heating process usually takes from 2 to 4 minutes, depending on the power of the device. Periodically check the temperature with your finger - the glass should become hot, but not burning.
After enough warming up, take a suction cup or a thin plastic map and try to create a small gap between the frame and the glass. If the glass doesn't lend itself, don't use force, add a little more heat. Put a plastic blade into the gap and carefully drive it along the perimeter, cutting the adhesive layer.
Move slowly, avoiding dipping the blade too deep to avoid damaging plumes or components near the edges. Pay special attention to the areas around the camera module and fingerprint scanner if it is built into the case. Gradual separation of the panel will reduce the risk of its destruction.

If there is no suction cup at hand, you can use a strong adhesive tape folded in several layers to create a handle for pulling the glass.
Dismantling internal components and plumes
Once the back cover is successfully separated, the smartphone's interiors are accessed, but the lid cannot be removed completely in a hurry, often with thin plumes attached to the motherboard. In the Redmi Note 6 Pro, the fingerprint scanner can be integrated into the back panel, which requires special care.
Carefully inspect the inside of the lid that you remove, and if you see wires or plumes coming from it, carefully disconnect the connectors from the motherboard, and use a plastic blade or dielectric-coated tweezers to avoid closing the contacts.
Next, remove the plastic protective pad that covers most of the internal components, which is usually attached to several screws and latches, unscrew all visible screws using the appropriate screwdriver, and carefully remove the plastic.
Now you have full access to the battery and the lower board, and if you're looking to replace the battery or repair the charging connector, this is critical, and make sure all the connectors are properly disconnected and not damaged in the process of manipulation.

Replacement of the battery and work with modules
The battery in the Xiaomi Redmi Note 6 Pro is also attached to adhesive, making it difficult to remove. Under no circumstances do not try to tamper with the battery with metal objects - this can cause it to puncture and fire. Use a plastic card and heat for safe dismantling.
First, disconnect the battery plume from the motherboard to de-energize the device completely. Then apply some alcohol or special solution under the edges of the battery and wait a couple of minutes. Carefully tuck the battery into the map, gradually separating it from the case.
When installing a new battery, make sure the contact pad is clean. Use double-sided tape or special adhesive strips that come with the new battery to fix it. Do not use superglue or other harsh chemicals that can damage the insides.
If you're auditing other modules, such as a vibro motor or a speaker, check their condition. Often, problems with sound or vibration are solved by simply cleaning the contacts or replacing an inexpensive module. All actions must be coordinated with the technical documentation.
โ ๏ธ Attention: Bloated battery is strictly forbidden to pierce or bend. Dispose of it according to the safety regulations for lithium polymer batteries.
Assembly of the device and installation of a new cover
The phone is assembled in reverse disassembly, before installing the new back panel, you must carefully clean the frame of the residue of old glue, use alcohol and soft cloth or a plastic blade to remove all irregularities.
On a cleaned and fat-free frame, apply a new layer of glue (such as the B-7000) with a thin, uniform layer or glue the finished adhesive base. Let the glue dry a little (1-2 minutes) so that it becomes less fluid but retains stickiness.
Carefully combine the new lid with the frame, starting on one side. Make sure that all the holes under the camera and speakers match. Tightly press the panel around the perimeter, paying special attention to the edges to ensure leakage.
Once the lid is installed, it is recommended to lock the smartphone with rubber bands or place it under a small load for 15-20 minutes to polymerize the glue. Don't turn the device on immediately, let the glue grip. Complete drying takes several hours.

Common Errors and How to Resolve Them
In the repair process, beginners often make mistakes that can cause the device to break, and one of the most common is excessive force when opening the case, and if you feel strong resistance, the glue is not warm enough or you forgot to unscrew the hidden screws.
Another common mistake is to damage the plumes when the tool is not working sloppy. The plumes in the Redmi Note 6 Pro are quite thin and easily torn. Always use backlight and magnifying glass when working with small components.
The table below will help to systematize possible problems and methods of their solution:
| Problem. | Possible cause | Decision |
|---|---|---|
| The lid's not off. | Insufficient heating of glue | Continue heating with a hair dryer, add a solvent |
| Phone's off. | The display or battery plume has gone away | Reconnect connectors, check the charge |
| The scanner's not working. | Scanner plume damaged. | Replace the scanner plume or module |
| There's a gap. | Curve installation or debris in glue | Remove the cover, clean, overheat and glue again |
Mindfulness and lack of haste are the master's main allies. If you're unsure of your abilities at any stage, it's best to stop and consult with more experienced colleagues or watch video guides. The most critical area when disassembling the Redmi Note 6 Pro is the area around the main camera module, where important plumes pass.

High-quality cleaning of the frame from the old glue is a guarantee that the new cover will hold reliably and will not peel off after a week.
