Fixing Xiaomi bootlap: phone reboots without stopping

What is a bootloop

A bootloop is an endless cyclical loading of a smartphone. The phone cannot start Android and therefore keeps rebooting after showing the logo. The word bootloop is formed from two English words “boot” (boot) and “loop” (loop).

The essence of the problem is that the Xiaomi bootloader for some reason cannot start. The result is a cyclic reboot. There are several ways to correct the situation.

First you need to determine the cause of the problem. It’s almost impossible to name the reason right away, so you have to try all possible solutions to the problem and hope that at least one of them will work.

How to fix bootloop

Looking ahead, we’ll warn you: if the words “root”, “recovery”, “TWRP”, “flashing”, “drivers”, “bootloader” are unfamiliar or scary to you, and you don’t have the time/desire to delve into it, bootloop can only be cured in a service center. Studying on your own from scratch can take a lot of time and nerves, and an occasional mistake can “finish off” your smartphone. If all this does not frighten you, further instructions are for you.

The first thing to do when eliminating a bootloop caused by a flashing failure is to turn off the smartphone and try to go to the recovery menu. Usually it starts if, with the device turned off, you simultaneously press “sound +” and “power” until the menu appears. Sometimes you also need to simultaneously hold down the “home” button (for some Samsung) or the “sound -” button (Nexus). But not all models have recovery: for example, Xiaomi 2021 has a locked bootloader without a recovery menu.

In the menu you need to find the Android factory reset item (“hard reset”, “wipe data”, “factory reset”, or the like). Moving is usually done using the volume rocker, selection is done with the power button. If the firmware is not damaged, resetting will save you from constantly rebooting your Android smartphone.

Recovery Menu

If the cause of the bootloop was a failure when updating the Android OS or during the process of uploading new firmware, you will have to “dance with a tambourine” on your PC. First of all, you should download drivers for your smartphone in order to connect it for flashing. The next step is to download software designed to load Android onto your smartphone. For Samsung it is Kies or Odin, for LG it is LG FlashTool, for Sony it is Sony Update Service Pro. Lenovo are sewn through FlashTool and other utilities (depending on the chipset), Xiaomi - through XiaomiFlash. The program for flashing a specific model should be checked on the official website or specialized forum, where you can also find instructions.

The third step is to download the firmware, after which the phone (following the instructions) needs to be connected to the PC, select the firmware file, set the parameters and start flashing the firmware. We warn you: this method of getting rid of bootloop is recommended only for experienced users. Errors made when uploading Android software can make a cyclic reboot incurable, turning the device into a “brick.” If you are not confident in your abilities, it is better to contact the SC. The same applies to hardware damage. Flashing the Android OS yourself will not help get rid of them.

The Android operating system is the most used. But her work has its own nuances and problems. The problem with the advent of Xiaomi Bootloop is quite relevant. Many Xiaomi smartphone users are faced with the fact that their smartphone constantly reboots, showing only the logo, and does not move further. Why this happens, what to do and how to prevent it will be discussed in this article.

Reasons for cyclic reboot

The device never stops rebooting for a reason. There are always prerequisites for this. The problem is that it is not so easy to understand what user action caused the problem.

Let's look at the main reasons for bootloop on Xiaomi:

1. Critical corruption of Android files. Most often it occurs as a result of viruses and other malware. It also happens if the user installed root and decided to slightly change the system files.
2. Incorrectly installed firmware. This happens if the firmware of the device was carried out with errors. Or the user tried to install an assembly that is not suitable for his phone.
3. Crash during bootloader unlocking. If you decide to unlock the Xiaomi bootloader and something goes wrong, then the appearance of a bootloop is a completely expected result. There is a custom solution for this problem.
4. Failure during Root installation. If you decide to install superuser rights using TWRP recovery, then even the slightest error during the installation process can lead to such consequences.
5. Damage to the memory chip. The most unpleasant option. If the memory chip with the boot record is damaged as a result of a fall or water entering the smartphone, the phone will reboot all the time. There is only one way out: go to the service center.

In any case, the problem is related to the bootloader - the system cannot start because of it. Usually the simplest methods help, but sometimes you have to bring in heavy artillery in the form of a console and ADB drivers.

What causes bootloop?

Cyclic rebooting, in most cases, is a consequence of corruption of the Android system software. Most often, bootloop happens if you upload an incompatible software version. It also occurs if the firmware process was completed incorrectly (for example, the power was suddenly turned off). Another possible reason is problems updating the software. If the battery runs out during the over-the-air firmware update process, the reboot may take forever due to corruption of Android OS files.

A bootloop also occurs when an inexperienced user changes system files while having root access. Incorrect editing of build.prop, in order to fine-tune Android for yourself, very often causes a bootloop. Malicious programs are very rarely able to put the device into a cyclic reboot state, since they need root access to do this. The last reason for the appearance of bootloop is hardware malfunctions of the chipset, memory (RAM or permanent memory), and communication modules.

Solution 1: Reset your phone (Hard Reset)

Resetting your phone to factory settings in most cases helps solve the problem of Xiaomi always loading.

The essence of the reset is that all data is deleted from the smartphone, and system files are restored to their original form. So if the problem is caused by Android file corruption, this option will help.

Attention! After the reset, all user files located on the internal storage will disappear: photos, videos, music, programs, documents. Therefore, you should not neglect synchronization with Mi Cloud. This option will allow you to quickly recover lost information.

Hard Reset in stock recovery

To do this, when you turn on Xiaomi, you need to additionally press the volume up button. Standard recovery (installed by default) differs significantly from custom recovery, which users install themselves.

I have already described in detail how to reset Xiaomi to factory settings via recovery. I repeat:

1. Turn off your phone.
2. Hold down the Power and Volume Up buttons.
3. Select Wipe Data.
4. Tap on Wipe All Data (delete all data).
5. Confirm by selecting Confirm.
6. The reset procedure will begin, upon completion of which the message Data wiped successfully will appear.
7. Return to the main menu, select Reboot → Reboot to System.

After the reset, the phone will reboot itself and launch MIUI. The first launch may take up to 15 minutes, depending on the smartphone model. Therefore, you need to be patient.

After the restart, the Xiaomi phone will have to be configured as if it was just purchased.

Hard Reset in TWRP

TWRP custom recovery does not look like stock recovery at all. The factory reset process is a little more complicated there. However, TWRP supports the Russian language, so working with it is much easier.

There are 2 reset options: standard and full. Let's look at both.

Standard TWRP method:

• Turn off your phone and enter recovery using the Power and Volume Up buttons.
• Go to the "Cleaning" section.
• Move the slider to the right.
• Once the process is complete, return to the main menu and select Reboot.
• Tap the “System” button.

After the restart, you will receive a completely clean smartphone without applications and user files, with a corrected bootlap. You will even need to set up a Google account.

• Tap the “Selective Cleaning” button.
• Check all the boxes except Vendor, OTG and SD card.
• Confirm the action by moving the slider to the right.
• When the process is complete, click on the “Reboot to OS” button.

A full option to reset to factory settings, if after a normal reset the phone still reboots endlessly and does not turn on. Using this procedure, you can delete everything from the internal drive.

How to fix constant reboot on Xiaomi?

The first method means you need to restore your MIUI backup. A prerequisite is the installation of a third-party recovery, for example, TWRP. It is recommended to back up your data in advance.

To enter the Recovery format, you need to hold down the Volume Up key and the Power button at the same time. A menu appears, one of the items is Wipe. We select it, which leads to the deletion of the current information. If formatting is carried out without a backup copy, all data will be permanently deleted from the phone's memory.

When the operation is completed, you need to return to the main menu, where you click on Restore. All that remains is to indicate the path where the previously saved data is stored and give confirmation for the operation. It is advisable to prohibit subsequent shell updates.

Solution 2: flashing

Reflashing will help if the problem of endless startup is a damaged bootloader or the absence of some operating system files.

If after flashing the phone constantly reboots, there is no other way to fix it. You can install stock firmware or custom one.

Installing official firmware

To do this, you will need the latest firmware for a specific smartphone (required the Global version), a program for installing the latest MiFlash Pro firmware, as well as suitable ADB drivers for the device.

The firmware is installed in Fastboot mode - follow the link for my detailed instructions on how to do this.

This option allows you to save user files. At a certain stage, it is enough to select save user data instead of clean all and lock. The instructions on the link talk about this.

Installing custom firmware

In this case, TWRP recovery is used to treat the cyclic reboot of Xiaomi. You will need the firmware itself in ZIP format, Google Apps (if not included in the firmware), the Magisk package (for installing Root), as well as the necessary fixes and corrections. All this needs to be put into the root of the memory card.

I have already talked in detail about the process of installing custom using TWRP. The first boot after installation can take up to 15 minutes, depending on the type of firmware and its key features.

Attention! To install the custom you will need an unlocked bootloader and TWRP recovery. If this is not the case, then without a working phone you will not be able to unlock the bootloader and roll out the recovery. Therefore, it is better to limit yourself to installing the official MIUI firmware.

Part 1: What can cause bootloop problems on Android?

Android boot loop error may seem strange and inexplicable, but it happens due to some specific reasons.

First, note that it is incorrect that the boot loop error only occurs on the root device. Android boot loop error can also occur in the presence of a device with original software, ROM and firmware.

In a rooted device, changes such as ROM flashes or customized firmware that are not compatible with the device's hardware or existing software may be blamed for the boot loop task.

Moving on, when your device's software fails to interact with system files during the startup process, Android boot loop problem may occur. This glitch occurs if you have recently updated your Android version.

Moreover, corrupt App update files can also lead to Android bootloop issue. Applications and program downloaded from unknown sources bring a certain type of virus that prevents you from using your device smoothly.

All-in-all, the Android boot loop error is a direct result of trying to tamper with your device's internal settings.

Therefore, if you are looking for ways to guide you on how to fix the boot loop problem, you will have to update your device internally either by reinstalling it or adopting a recovery method.

Read on to know more about how to fix bootloop error without losing data when your device is suffering from bootloop Android problem.

Solution 3: Fix using ADB

Console and ADB are powerful tools to fix bootloader issues in Xiaomi phone. You will need to download the ADB package for a specific smartphone and install it on your computer along with the appropriate drivers.

I have already talked about the bootloader recovery process using ADB. Do not forget that after completing all the steps you will need to reboot the phone with the fastboot reboot .

To work with ADB, you only need an original Xiaomi USB cable. Chinese analogues do not always provide a stable connection. And disconnecting the phone from the PC at the most crucial moment can completely kill the smartphone.

Looped reboot that ends at the MIUI logo

First of all, it is necessary to consider this particular option, since its reasons are more significant. It may occur in the following cases:

• An update to the Android operating system was installed independently or automatically, but despite bug fixes in the previous version, the new one may contain others;
• The software was installed on the smartphone via PC or recovery TWRP;
• Before the last restart of the smartphone, a new application was installed;
• In a smaller number of cases, the cause may be a discharged battery or a breakdown;
• A number of standard situations should also be taken into account, for example, falls on a hard surface, water entering the case, as well as accidental manipulation of the device, a child or a pet.

Solution 5: Contact a service center

If software methods do not help cure a phone stuck on reboot, most likely the problem is hardware in nature and related to the memory chip. It is impossible to repair such a smartphone yourself. You will need to contact an official service center.

To visit the service center, you will need documents from your Xiaomi phone and you may be asked to confirm your identity using a passport.

It is better to refrain from going to unofficial workshops. It’s not a fact that you’ll find a good specialist. Many unofficial firms hire non-professionals, and such a “master” can only make matters worse. Especially if you need to replace the memory chip (the work is delicate and complex).

Bootloop is a very annoying problem in which the phone constantly turns on and off. In most cases, Xiaomi constantly rebooting can be fixed using software methods at home. But it is important to carry out all actions in strict accordance with the instructions. Otherwise, you can completely kill the phone.

Reboot related issues

There are 2 common failures of Redmi devices. In the first case, when the gadget turns on, the MI logo appears on the screen. After waiting a few seconds, it turns off and then lights up again.

The second problem is that the gadget works as usual, but at the most inopportune moments it reboots on its own. Such shutdowns are repeated 2-3 times a day. There are also situations when the problem appears every hour.
