When the beloved Xiaomi Redmi Note 6 Pro suddenly stops responding to pressing, the screen remains black, the indicators are silent, and it seems that the device finally failed. However, in most cases, the problem lies not in the fatal failure of the motherboard, but in a software failure or deep battery discharge that can be fixed on your own.
Before you carry a gadget to a service center, you need to conduct a thorough diagnosis to rule out simple causes. Often users confuse the “dead” state of the phone with a deep sleep mode or a system freeze, which is solved by simple manipulation. In this article, we will analyze all possible scenarios, from trivial discharge to complex hardware malfunctions, and offer step-by-step instructions for restoring performance.
It is important to understand that the algorithm of actions depends on what exactly preceded the problem: a fall, moisture or just a software update. Follow the instructions carefully so as not to aggravate the situation. Sometimes, resuscitation of the Redmi Note 6 Pro requires only the right combination of buttons or a long connection to the charger.
Primary diagnosis and exclusion of battery discharge
The most common reason Xiaomi Redmi Note 6 Pro doesn’t turn on is because of the critical discharge of the lithium-ion battery.When voltage drops below a certain threshold, the power controller blocks the system from starting to prevent damage to the battery cells.
You need to leave the device on charge for at least 30-40 minutes, even if the screen remains black. Use only the original cable and power supply with sufficient current, as weak charges from other gadgets may not “swing” the battery. If after half an hour nothing appears on the screen, try to replace the cable, as the wires often bend and fail.
⚠️ Warning: If the case of the smartphone is swollen or from the heating went unpleasant chemical smell, immediately stop charging.
Sometimes the battery push method helps. To do this, connect the phone to the computer through the computer. USB-The computer delivers a current of less force but stable voltage, which in some cases helps the controller wake up and start charging normally. If after 40 minutes the screen still hasn't caught fire, move on to the following methods.
Forced reset and static voltage reset
If the battery is charged, but the Redmi Note 6 Pro still does not respond, most likely there was a software “hang” or accumulation of static electricity in the power chains. The system could go into an endless cycle of errors, blocking the response of the touchscreen and buttons. In such cases, a regular shutdown is impossible, and a hard reset button is required.
To do this, hold the Power button for a long time, 15 to 30 seconds. Keep your finger on even if the phone starts to vibrate. Your goal is to completely break the power circuit and start the controller again. If it didn't work the first time, try the button combination: Hold the Volume Down and Power for 20 seconds at the same time.
This is a safe method for your data, because it doesn't erase information, it just reboots the hardware, and unlike a full reset, you don't need access to the menu, and often after that, the phone starts vibrating and shows the Mi or Android logo.
☑️ Hard reset algorithm
It’s worth noting that some revisions of Xiaomi motherboards may work with protection against accidental pressing in your pocket. If you carry a phone without a case, the button may have been pinched for a long time, which led to artificial discharge or freezing, in which case prolonged charging in the off state will also help solve the problem.
Enter Recovery and Fastboot Mode
If a normal reboot fails, check the availability of system partitions through special boot modes. Recovery mode allows you to reset to factory settings or clear the cache, and Fastboot mode is designed to flash the device through the computer.
To enter Recovery, press the Up Volume and Power button at the same time. Hold them until the Mi logo appears, then release Power, continuing to hold Up Volume. If the menu appears (usually in English or Chinese), then the display and touch controller are good and the problem is in the operating system. Select Wipe Data for a full reset (data will be deleted) or Reboot for a normal reboot.
What to do if the menu is in Chinese?
Fastboot mode is called by clamping Loud Down and Power. The screen should show a hare in a hat-eared android fixing, or the inscription FASTBOOT. If this mode starts, but the system does not load, the problem may be in the damage to the Android system files, in which case you will need to flash through the utility Mi Flash Tool.
Below is a table that helps decipher the state of the device by the reaction to buttons:
| Device response | Probable cause | Action required |
|---|---|---|
| Vibration without image | Display or plume malfunction | Checking the flashlight illumination |
| Blinking the Mi logo | Firmware failure (Bootloop) | Entering Recovery or Flashing |
| Total lack of response | Discharge, button or motherboard | Long-term charging, disassembly |
| Heating in the processor area | Short circuit (SRC) | Urgent repairs in the service |
Problems with the on button and plumes
The Redmi Note 6 Pro has a design feature: the power button is located on a plume that can oxidize or depart over time. If the phone doesn't turn on but it makes a sound or vibrates when connected to charging, there is a high probability of a mechanical malfunction of the button, it could simply "stick" or lose contact with the board.
Try to push the power button lightly but confidently at different points on its surface while connecting the charging cable. Sometimes this helps to close the contact. If you have experience disassembling smartphones, you can carefully remove the back cover (it is glued, you need a hairdryer) and turn off the button plume, and then close the contacts on the board with tweezers for inspection.
⚠️ Warning: Self-disassembly of the smartphone voids the warranty. If the device is still under warranty, do not open the case, and contact an authorized center.
It's also worth checking the display and battery plumes, and if you fall, the connectors could move away. A careful reconnection (with battery power beforehand) often brings the phone back to life. However, if you're not sure about yourself, it's best not to take risks, because sloppy movement can damage fragile tracks on the board.
Hardware malfunctions of the motherboard
If none of the software methods worked, and the phone shows no signs of life even when connected to the computer (the computer does not make a USB connection sound), it is a serious hardware failure. In the Xiaomi Redmi Note 6 Pro, a common cause is the failure of the power controller or memory chip (eMMC).
Symptoms of hardware failure can be: strong heating of a certain area of the case when trying to turn on, no current consumption (0.00 A on the power supply) or, conversely, the consumption of current without starting (short circuit).
In such cases, professional diagnostics are required using a microscope and a laboratory power supply unit, the wizard will be able to determine exactly which element consumes current or, conversely, does not pass it. BGA-components at home is almost impossible without special equipment.
💡
If the phone is using current, but the screen is black, it's probably a problem with the display or its plume, and if there's no current at all, it's a problem with the power chain or the battery.
When professional repairs are needed
There are a number of situations where further attempts to revive a smartphone with your own hands can only harm, if the phone does not turn on after falling into the water, it cannot be dried with a hairdryer or put on the battery - the moisture inside causes corrosion, and the heat will only accelerate this process, such a device should be carried into the service as quickly as possible.
Also, if you connect to the charger, the phone starts to warm up in the camera or processor, which is a sure sign of short circuit inside the circuit, and if you continue charging, you can burn the board up or burn it out completely, making recovery impossible or economically uneconomical.
The cost of repairing the Redmi Note 6 Pro varies depending on the malfunction.Replacing the battery or charging plume is inexpensive, whereas replacing the power controller or rolling over the processor can cost a lot of money.Sometimes it's easier to buy a new smartphone than repairing an old flagship if the cost of work exceeds 70% of its market price.
