A situation where your Xiaomi Redmi Note 4 is constantly rebooted can take you by surprise and cause panic.This phenomenon, known as bootloop, often indicates a software failure or hardware malfunction, which owners face after a failed upgrade, device drop, or simply because of the wear and tear of components.
Before you bring your smartphone to the service center, you should try to conduct a self-diagnosis, in many cases, you can bring it back to life without financial investment, if you act consistently and carefully, the main thing is not to make hasty actions that can aggravate the state of the operating system.
The next steps depend on where the failure occurs, whether it's when you load the logo, when you load the menu, or when you launch the apps, and understanding the nature of the problem is half the success of solving it, and we'll look at the basic methods of resuscitation, from simple reboots to complex firmware manipulation.
Primary diagnosis and simple methods
The first thing to do is rule out the trivial reasons that are often ignored.If the Redmi Note 4 reboots indefinitely, check the status of the power button.Mechanical sticking or damage to the plume can close the circuit, making the phone think you're holding your finger on the button.
Try to do a forced reboot, and then press and hold the power button for a while. 10-15 If the device reacts and vibrates, there's a chance that the system is just stuck in a cycle of errors. SIM-cards and memory cards before switching on.
Notice the behavior of the screen and notification indicator. Blinking the indicator or getting stuck on the Mi or Android logo gives a clue about the nature of the crash. If the phone is heated off when connected to charging, this may indicate a short circuit in the power chain.
It is important to check the integrity of the charging cable and the power supply. Unstable voltage can cause the system to start cycling, as the processor does not have enough power to function properly. Use only original or certified accessories to charge your smartphone.
Safe mode and diagnostics of applications
If the device manages to reach the lock screen, try running it in Safe Mode, which disables all third-party applications, allowing you to determine whether the recently installed software failed.
In Safe Mode, carefully review the list of installed programs, remove any suspicious applications, especially those with administrator rights or deep access to the system, often caused by "optimizers", "antiviruses" or applications to change the interface.
⚠️ Warning: If the phone is stable in safe mode, the problem is 99% in third-party software.
Once you remove potentially dangerous applications, restart your device as normal, and if the reboot cycle is over, the conflict is over, or you'll have to move to more radical recovery methods through Recovery.
Use of Recovery Mode
Recovery mode is a diagnostic environment built into the phone's memory, regardless of the main system, and can be accessed by turning off the phone (if it turns on) and holding up the volume and power buttons simultaneously, and a menu with several items in English or Chinese should appear on the screen.
In this menu, you can navigate with volume buttons and you can choose with power buttons. You can find Wipe Data or Wipe & Reset. Note that there are different types of resets: Wipe All Data deletes everything, and Wipe Data (Keep User Data) tries to save photos and contacts, but resets.
☑️ Checklist before data reset
Once the cleaning option is selected, the system will request confirmation, often requiring you to type in the word yes or press Confirm.The process can take several minutes. Upon completion, the phone will prompt you to restart (Reboot).
Fastboot and Mi Flash Firmware
When the soft techniques don't work, and the Xiaomi Redmi Note 4 continues to reboot, it requires a complete flashing. It uses Fastboot mode, which is activated by pressing the power and volume button "Down," and an image of a hare repairing an android will appear on the screen.
You'll need a computer, USB-You also need to download the firmware image for your model (codename markw for the global version or mido for the Indian / Chinese version.
| Parameter | Description | Importance |
|---|---|---|
| Firmware mode | Clean All (Full Cleaning) | Tall. |
| Drivers. | Qualcomm / ADB Interface | Critical |
| Battery | Minimum 40-50% | Tall. |
| Cable | The original USB | Medium |
In Mi Flash Tool, select the path to the unpacked firmware folder, connect your phone in Fastboot mode, and press the Flash button. At the bottom, select the Clean all option to avoid file conflicts. The process will take 200 to 500 seconds.
What to do if Mi Flash is making an error?
Once the firmware is successfully installed, the phone will automatically restart. The first load can last up to 10 minutes. If the cycle repeats even after a clean firmware, the probability of hardware failure tends to peak.
Hardware problems and the “dump” of memory
The Redmi Note 4 is notorious for a specific hardware problem that involves the eMMC or CPU contacts going off, which is caused by the body deforming when it falls or thermally expanding when it heats up, and the symptoms are that the phone is hanging on the logo or going into a permanent reboot.
Diagnosing dumps at home is difficult, but you can try the warm-up method. Some users temporarily restore work by gently warming up the processor area (under the screen) with a hairdryer or putting the phone on a hot (but not boiling water!) surface, which allows the contact to temporarily close.
⚠️ Warming is a temporary measure to save data, not repair! The effect can last from a few minutes to a couple of days.
If after heating up and then flashing the phone again began to reboot after a while, then the soldering contact is broken, in which case the software methods are powerless. A visit to the workshop is required to perform the rebolling procedure.
Prevention and care of the device
To avoid a repeat of the Redmi Note 4’s reboot, follow the rules of operation.Do not let the battery go to zero on a regular basis, as deep discharge damages the power and memory controller.
Use a protective case that cushions the impacts of a fall. It is mechanical shocks that most often lead to microcracks in the soldering of chips. Also, try not to overheat your smartphone while playing heavy games while charging.
💡
Clean your phone’s memory regularly from garbage and don’t fill the internal storage completely. Free space is needed for temporary files and the cache to work properly.
Update your software on time, but avoid installing betas or custom builds from untested developers. The stability of MIUI depends on the integrity of system files.
💡
If software reset and flashing did not help, the problem lies in the “hardware” (memory or processor), and professional repairs are required by soldering.
