2. Heat the back cover around the perimeter with a hair dryer for 1-2 minutes. The temperature should be about 60-70.°C – Do not overheat to avoid damaging the plastic!
3. Insert a plastic mediator into the gap between the housing and the cover (start at the bottom edge where the connectors are located). Carefully drive the mediator along the perimeter, separating the latches.
4. Take the lid off and put it aside, and underneath it you'll see the battery, the motherboard, and the plumes.

Now we need to turn off the battery.

1. Unscrew 4 screws that fix the metal plate over the battery connector (they can be under the fillings - carefully cut them with a knife).
2. Put the battery connector in the mediator and disconnect it from the motherboard.

⚠️ Warning: If you see traces of oxidation or green plaque on the contacts when you disconnect the battery, you need to clean them with alcohol and cotton cotton, and ignoring this will lead to unstable operation of the smartphone after repair.

At this stage, it is also recommended to photograph the location of all plumes and screws, which will help avoid confusion when reassembling. If you have never disassembled smartphones, pay attention to the color of the screws - they can vary in length!

Step 2: Disconnect the touchscreen plume and display

Once the battery is turned off, you can start dismantling the screen, which is the most important step: damage to the plume will lead to the need to buy a new module.

The touchscreen plume in the Redmi Note 5A It's located under a metal plate at the top of the device to get to it:

1. Unscrew 6 screws holding the plate (they can be of different lengths - remember where it was).
2. Carefully put the plate in the mediator and take it off, and underneath it you'll see two plumes: one going to the touchscreen, the other going to the display.
3. With a mediator or tweezers, unplug both plumes from the connectors on the motherboard. Pull strictly upwards, not to the sides!

Now we need to separate the screen from the body.

1. Heat the front panel of the smartphone around the perimeter with a dryer (temperature - 70-80)°C) The glue under the screen shall soften.
2. With a suction cup, grab the screen closer to the bottom edge and pull up slightly. If the screen doesn't respond, warm up again.
3. Put the mediator in the gap and carefully guide it along the edges, separating the screen from the body.

Once the screen is separated, put it on the table with the display down. Don't put it on the plumes, they may get damaged. Now you can start installing a new touchscreen.

• 🔌 Trail damage - occurs when sloppy disconnection or excessive tension. Always pull the plume strictly upwards, not to the sides!
• 🔥 Overheating of the body - if the temperature of the hair dryer exceeds 90°C, plastic can deform. Use a thermometer or keep a hair dryer 5-7 cm away.
• 📱 Incompatible screen – check your Redmi Note model before buying 5A (The screens for these versions may differ from the usual or Prime!

If the screen does not respond to touch after replacement, but the image is present, the problem may be:

• Incomplete connection of the touchscreen plume (check the connector).
• Damage to the touchscreen controller on the motherboard (diagnosis is required).
• Marriage a new screen (try connecting the old one – if it works, the problem is in the parts).

If the screen is not turned on at all, check:

• Battery connection (possibly the connector has gone).
• Integrity of the display plume (in case of damage, the image will be absent).
• The motherboard is operational (plug in a knowingly serviceable screen).
