When your Xiaomi suddenly starts to reboot endlessly, throwing the user onto the Mi or Redmi logo and then starting the cycle anew, it causes panic.This phenomenon, often referred to as a “bootloop,” can be caused by both a software glitch after a failed update and critical hardware errors. It is important to remain cool, as panic actions such as chaotic button pressing or connecting to the first charger that comes across can make things worse.
Before you bring your gadget to the service center, you should try a number of self-steps that in most cases bring the device back to life. Cyclical reboot is often a protective reaction of the system to file conflict or memory overflow, rather than a sign of final failure. Below we will discuss in detail algorithms of actions, ranging from simple manipulations to complex firmware procedures through the computer.
The success of recovery depends on the accuracy of the instructions and understanding the nature of the failure. SIM-In some cases, the map will require full data formatting, and the critical factor for success is the battery level, which should be at least equal to the level of the battery. 40-50% If you ignore this requirement, the phone can shut down at the most critical moment, causing damage to the bootloader.
Diagnostics of the causes of an infinite cycle
The first step is always to identify the source of the problem. Most often, software conflict occurs after installing applications from unknown sources or failing to modify system files. If you recently obtained root rights or installed custom recavators, the probability of error in these actions tends to maximize.
But you can't discount hardware problems, too. Mechanical damage, moisture or just wear of the power button plume can create a sticky effect. The phone thinks you're always holding your finger on the power button, and it keeps rebooting. It's also worth checking the volume button, because it can automatically send the device into recovery mode.
⚠️ Warning: If the device falls or comes into contact with water, any attempts to charge it or connect it to a PC without first drying and diagnosing can lead to a short circuit of the motherboard.
Often, the cause is overcrowded memory. When the system partition lacks space for temporary files and logs, the Android operating system cannot properly complete the boot process, in which case the phone can turn on, show the desktop for a second and go out again, which is one of the easiest cases to fix if you have time to enter Safe Mode.
Forced reset and retrieval of elements
The simplest and often ignored method is to completely shut down the device. If the battery in your Xiaomi is removable, just remove it, wait a minute and insert it back in. This will relieve the residual voltage from the capacitors and clear the RAM from errors. For models with a non-removable battery, this stage requires a longer hold on the power button.
You need to press the power button and hold it for 15-20 seconds. The screen can go out and light up, vibrate - don't let go of the button until you feel the characteristic vibration or see the logo. If that doesn't help, try a combination of power and volume buttons (top or bottom), as on different models the hardware reset can be tied to different combinations.
It's also important to check the periphery. SIM-A damaged file system on a memory card can block the OS from booting because Android tries to read it at start. If the phone calmly boots after removing the flash drive, the problem lies in the drive or its contents.
☑️ Primary diagnosis
Using Recovery Mode to Reset Settings
If simple methods don't work, you'll have to use the system partition to get into Recovery Mode, turn off the phone (if it allows) or wait until the screen goes out, and quickly press the volume button along with the power button. Hold them until the Mi logo appears, then release power, but keep the volume.
In the Recovery menu, you have to use volume buttons (up/down) and the power button to confirm your choice. You need to find Wipe Data or Factory Reset. Remember, this step will completely delete all your photos, contacts and apps. However, this is often the only way to remove the software conflict that blocks the download.
After selecting the reset point, the system will ask you to confirm the action, usually you need to select Confirm or enter the word "yes." The formatting process can take several minutes. Upon completion, select Reboot -> Reboot to System. The first start after the reset will last longer than usual - up to 5-10 minutes, as the system creates new configuration files.
⚠️ Warning: The Recovery menu has a "Wipe All Data" option that deletes everything, including the contents of internal memory. Be careful not to confuse it with "Wipe Cache" unless your goal is to clean up completely.
Sometimes, after a reset, the phone gets back into a loop, which may mean that the problem goes deeper than just a software crash of user data, in which case it may be necessary to flash the device through the computer using the Mi Flash Tool utility, but this already requires an unlocked bootloader or an authorized Mi Account.
What happens if Recovery does not open?
Fastboot mode and device firmware
Fastboot mode is designed to be low-level, low-level, and to enter, press the volume down and the power button at the same time, and you have to have a hare in a hat fixing an android on the screen, or you have to have the words "FASTBOOT." If the phone enters this mode and doesn't leave it, that's a good sign, so the processor and the basic memory are working.
To restore the workability through Fastboot, you will need a computer, USB-cable and official firmware in.zip format (Recovery) ROM) or.tgz (Fastboot) ROM). Mi Flash Tool allows you to flood a clean system on top of a damaged one. It is important to choose the correct firmware version that corresponds to the region of your device (Global, China, EEA), Otherwise, you can get a "brick" with non-functioning communication frequencies.
Fastboot often requires an unlocked bootloader, and if the bootloader is locked, the program will give an error, in which case official methods are limited, and the user has to contact the service to unlock through his Mi Account or wait 168 hours (week) after submitting an application in the Mi Unlock application.
| Type of regime | Button combination | Appointment | Data retention |
|---|---|---|---|
| Recovery | Volume + and Nutrition | Reset and update | Only when updated |
| Fastboot | Loudness - and Nutrition | Firmware and debugging | No (with full firmware) |
| Safe Mode | Off button on the screen | Diagnostics of applications | Yes. |
| EDL Mode | Special combination or fee | Deep recovery | No. |
💡
Fastboot mode is the “last frontier” of software recovery, allowing you to rewrite system partitions completely, ignoring the state of the operating system.
Problems with the on button and plumes
Often, the reason for Xiaomi's constant reboot is a physical malfunction of the Power button, which wears out, oxidizes or falls over time, and the contact closes inside the case without you, and the phone perceives this as a command to reboot, and you can check this by tapping the body in the area of the button or pressing it intensively, but carefully.
If you have the ability to disassemble electronics, you can gently open the back cover (preheat the perimeter) and disconnect the power button plume from the motherboard. If after the loop is turned off, the cyclic reboots stopped, then the problem is in the button. It can be temporarily left off to save important data, or replaced with a new one.
Also worth paying attention to is the state of the charging connector. In USB-C models, port pollution or contact oxidation can lead to voltage surges that the system perceives as a signal to reset. Cleaning the port with a toothbrush or compressed air sometimes works wonders.
💡
If you suspect a button sticking, try pressing it quickly and sharply (but without fanaticism) several times to mechanically unscrew the mechanism before disassembling the phone.
When Professional Assistance is Needed
There are situations where software methods and button replacements don't help. If the phone enters EDL (Emergency Download Mode) mode - the screen is black, but the computer makes the device connect sound - this often indicates a bootloader damage or critical memory error. Most modern Xiaomi models require an authorized Mi Account with paid access, which is only available from certified service centers.
Also, the reason for contacting the service is the lack of response to charging, strong heating of the lower part of the case (the processor area) even when turned off, or the appearance of foreign artifacts on the screen, these symptoms indicate hardware failure of the motherboard components, requiring soldering or replacement of memory and processor chips.
If the device is less than a year old and there is no trace of mechanical impact or moisture, any cyclical reboot is a warranty case. Attempting to self-firmware or open it can lead to the appearance of "Warranty Void" stickers, which will deprive you of the right to free repairs.
⚠️ Warning: Using third-party “wonder boxes” to unlock or firmware can permanently block IMEI communication module, turning the smartphone into a device without the possibility of calls.
