Xiaomi Redmi Note 4 is one of the most popular smartphones of the brand, but even it is not immune to system failures. Hanging on the logo, black screen after updating or sudden inresponsive interface are typical problems that owners face after 3-5 years of operation. In 80% of cases, a forced reboot helps, but many users are afraid to press the wrong button and finally break the device.
This article is a detailed guide to proven methods of rebooting without loss of data (in most cases).We will analyze not only the standard power button retention, but also alternative methods through Recovery Mode, Fastboot and even ADB for advanced users. We will separately focus on the nuances for different versions of firmware (MIUI Global, China, custom builds) and the typical errors that turn a simple reboot into a brick.
When a forced reset is needed
Not all hanging requires drastic measures. For example, if the smartphone is slow to respond to touch, but the menu still opens, just reboot it in a regular way through Settings โ About phone โ Reboot. Forced reboot is needed in critical cases:
- ๐ต The screen is completely black, no reaction to charging or connecting to a PC.
- ๐ The device got stuck on the Mi logo or download animation for longer than 10 minutes.
- ๐ค The system emits an Android.process.acore stopped or com.android.phone error in the loop.
- ๐ The phone is discharged โto zeroโ and does not turn on after connecting to charging.
- ๐ฎ Apps or games cause a โperpetualโ reboot (bootloop).
It is important to distinguish between freeze and hardware failures, and if the problem recurs after a forced reboot, it is possible to:
- ๐ Failure of the battery (blown, loss of capacity).
- ๐พ Damage to section /system or /boot (often after a failed update).
- ๐ Problems with the motherboard (for example, the dump of memory chips).
โ ๏ธ Note: If you have installed custom software before hanging out (for example, TWRP Or LineageOS, a forced reboot can cause data loss. In such cases, try connecting to your PC first. ADB.
Method 1: Classic button reboot (Soft Reboot)
The safest method, which works 90 percent of the time, is for a freezer interface, but it doesn't work with a black screen or a bootloop.
Instructions:
- Hold the Power button for at least 10-15 seconds until the screen goes out.
- After vibration and turning off the screen, wait 5-7 seconds.
- Press the power button to turn it on.
On the Redmi Note 4 (mido model), the power button is on the right. If the smartphone is in the case, remove it - sometimes the protection blocks full press.
Make sure the battery charge is >10%|
Turn off the charger (if connected)|
Check if the volume button is stuck |
Remove the case (if any)
-->
| Situation | Duration of retention | Expected output |
|---|---|---|
| Interface freeze | 10-15 seconds | Shutdown and normal start-up |
| Black screen (but vibrating) | 20โ25 seconds | Forced shutdown |
| Bootloop (Cyclical Reboot) | 30+ seconds | Switching to Fastboot or Shutting Down |
โ ๏ธ Warning: If after holding the power button, the smartphone went to Fastboot mode (on the screen of the hare in the hat-eared), do not panic - this is normal. Just select Reboot with volume buttons and confirm the choice of the power button.
Method 2: Reboot with Recovery Mode
If the classic method didn't work, try booting into Recovery Mode.
- ๐ The smartphone is stuck on the logo Mi.
- ๐ฑ The screen is working, but the sensor is not responding.
- ๐ The battery is discharged to 0% and the device does not turn on after charging.
Instructions for Redmi Note 4:
- Turn off your smartphone (hold the power button for 20 seconds if it doesnโt respond).
- Press the power button + volume button.
- Hold both buttons until the Mi logo and Recovery menu appear (usually 5-10 seconds).
- From the menu, select Reboot โ Reboot to System (use volume buttons for navigation and power button for confirmation).
If you have a customized Recovery (TWRP) installed, the menu will look different, but the logic is the same. In TWRP, select Reboot โ System.
What happens if the Recovery Mode does not open?
In the Redmi Note 4 on the Snapdragon 625 processor, there is a feature: if you hold the buttons longer than 15 seconds, the device can go to Fastboot instead of Recovery. To avoid this, release the buttons immediately after the menu appears.
Method 3: Reboot via Fastboot (for advanced)
Fastboot mode is a "service menu" of a smartphone that allows you to control the device via a PC.
- ๐ฅ๏ธ You have access to a computer with drivers installed ADB/Fastboot.
- ๐ง You are ready to use the command line.
- ๐ฑ The smartphone is determined by the PC in Fastboot mode (in the Device Manager appears Android Bootloader Interface).
Step-by-step:
- Turn off your smartphone (forced if necessary).
- Press the power button + volume down button for 10 seconds until the hare appears in the hat (Fastboot logo).
- Connect your smartphone to your PC through USB-cable (preferably original).
- On your computer, open the command line (Win + R โ cmd) and type:
fastboot devicesIf the device is determined (its serial number appears), enter the reboot command:
fastboot rebootIf the team doesnโt work, try:
fastboot -w reboot(The -w key clears the Dalvik cache, which sometimes helps with hanging).
โ ๏ธ Note: Fastboot erase or fastboot flash commands without understanding the consequences can lead to data loss or โbrickingโ of the device!
๐ก
If your PC doesnโt see your device in Fastboot, install the Qualcomm HS-USB QDLoader 9008 drivers or use the Mi Flash Tool program to install automatically.
Method 4: Reboot through ADB (if USB-debugging was included)
If you activated before hanging up USB-debugging (Settings) โ For developers, you can try to restart the smartphone through ADB. This method is rarely used for forced reboots, but can save you if other methods donโt work.
Instructions:
- Connect the Redmi Note 4 to your PC (even if the screen is black).
- Open the command line and check if the PC sees the device:
adb devicesIf the serial number appears in the answer, enter:
adb rebootIf the team doesnโt work, try:
adb shell reboot -p(This simulates a total power outage).
If ADB doesnโt see the device, but the smartphone is defined as Qualcomm HS-USB Diagnostics, you can try to put it into EDL mode (emergency firmware) using the command:
adb reboot edlBut this is an extreme case - after EDL, a complete firmware reflash is often required.
Method 5: Hardware reset (if nothing helps)
If all previous methods fail, you'll have a hard reset, which will cause data loss, but bring your smartphone back to life. There are two options on the Redmi Note 4:
Option 1: Recovery Mode
- Go to Recovery Mode (Power button + Volume up).
- Select Wipe Data โ Wipe All Data (in the drain recavator) or Wipe โ Format Data (in TWRP).
- Confirm the action and wait for the completion.
- Choose Reboot. โ Reboot to System.
Option 2: via Fastboot (if Recovery is not available)
You will need a PC with Fastboot installed and firmware for Redmi Note 4.
fastboot erase userdata
fastboot erase cache
fastboot rebootAfter a hard reset, the smartphone will return to factory settings. All data (photos, contacts, messages) will be deleted, so use this method only as a last resort.
๐ก
Hard reset is the last chance to bring the smartphone back to life, but it erases all data. If the device had important files, try connecting through ADB first or retrieving the memory card (if you have one).
Frequent Mistakes and How to Avoid Them
Even a simple reboot can go wrong if you make one of these mistakes:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Holding the power button too short (less than 10 seconds) | The smartphone is not restarting, continues to hang | Hold the button for at least 15 seconds until you feel vibration. |
| Use of unoriginal cable for Fastboot/ADB | PCs can't see the device, commands don't pass | Use a cable from the kit or a certified USB Type-C |
| Interrupting the process in Recovery or Fastboot | Damage to system files, bootloop | Do not turn off the cable or press buttons until the operation is complete. |
| Select Wipe Data instead of Reboot | Loss of all data | Read the menu items carefully before confirming |
Another common problem is that the smartphone doesn't turn on after the reboot.
- ๐ Fully discharged battery (you need to hold on charging for 15-20 minutes).
- ๐ Faulty cable or charger (try another one).
- ๐ฅ Firmware damage (reflashing through Mi Flash Tool required).
