The situation when the Xiaomi Redmi 8 suddenly begins to behave unpredictably, causing panic in the owner, is quite common.The device can endlessly reboot, showing the manufacturer's logo and going into the black screen, or freeze at a certain stage of booting the operating system. This behavior is often called a "bootloop" or cyclical reboot, and it can be caused by both a software failure and a physical malfunction of components.
The first thing to do is to look at prior events: Was there a questionable program installed, was the device hit or was it in a wet environment? Often it is a software conflict or a system memory overflow that triggers the gadget's unstable operation, and understanding the root cause will help you choose the right algorithm for restoring the device to work.
In some cases, the problem is the simple sticking of mechanical buttons, which is especially true for budget models. However, we should not rule out more serious problems with the battery or motherboard. In this article, we will discuss all possible scenarios in detail and offer step-by-step instructions for troubleshooting, ranging from simple methods to complex flashing procedures.
Diagnostics of hardware problems and control buttons
Before we go into complex software manipulations, we need to rule out the physical causes of the crashes. In the Redmi 8 model, as in many other Xiaomi smartphones, the volume and on buttons have a mechanical design that wears out or clogs over time. If the On or Down button is half-pressed due to dirt, oxidation or deformation of the case, the phone will perceive this as a constant signal to reboot or enter recovery mode.
Carefully inspect the ends of the device in good light. Try to press the buttons carefully: they must have a clear, ringing stroke without dips and sticks. If you feel that the button has failed or does not return to its original position, this is a sure sign of mechanical failure. In this situation, software methods will be useless, since the hardware failure requires physical intervention or replacement of the button module.
⚠️ Warning: Do not attempt to disassemble the phone yourself unless you have experience and a special tool.A careless autopsy can damage the plumes or impair the tightness of the case, leading to the device finally failing.
Often, the reason for an endless reboot is the use of an unoriginal or faulty charger. If the power supply gives off unstable voltage or current, the phone can go into a cyclical restart immediately after connecting to the network or, conversely, when disconnected. Try replacing the cable and adapter with a known serviceable, preferably original from Xiaomi, to exclude this factor.
Forced reboot and entry into Recovery mode
If the physical buttons are working properly, the next step is to try software reboots, and a standard shutdown may not work if the system is stuck. In this case, we use a forced reboot method, which is similar to the battery extraction in older phones, and you have to press the power button and hold it for a while. 10-15 The screen should go out, and then the device should vibrate and try to start again.
In case a normal reboot doesn't work, you'll need access to the Recovery Mode menu. This is a special diagnostic interface built into the firmware that allows you to clean up memory or reset even if the main system isn't booting. To enter this mode on the phone turned off (or when it's stuck on the logo), you need to simultaneously press the volume button and the power button. Hold them until the Mi logo appears, then release power, but keep the volume up until the menu appears in English or Chinese.
☑️ Pre-reset check
In the Recovery menu, you can navigate with volume buttons (up/down) and power buttons. You need to find the Wipe Data option. However, be very careful: choosing Wipe All Data will completely delete all information from the internal drive, including photos, contacts and applications. If you want to save data, try choosing Safe Mode (if available) or simply Reboot first to see if this will fix the temporary failure.
⚠️ Note: Resetting your data through Recovery will delete all personal information without recovery. Use this method only as a last resort when other methods have not helped.
Full reset (Hard Reset) through the menu
When the system is damaged so much that normal booting is impossible, the only solution is often a complete factory reset, which returns the software to its original state by removing all user data, app cache and system errors accumulated during operation. For Xiaomi Redmi 8, it is a standard recovery procedure that helps in 80% of software failures.
To perform Hard Reset via the Recovery menu, log in as described above. Select the language (if the menu is in Chinese, navigate by icons or button position, usually the language is the second button on top). Next, go to the Wipe Data section and select Wipe All Data. The system will request confirmation of action, as this is a critical operation. After confirmation, the formatting process will begin, which can take several minutes.
What to do if the Recovery menu is in Chinese?
After the cleaning process is complete, the phone will suggest returning to the main menu (Back to Main Menu) or immediately restarting (Reboot).The first boot after the reset will last longer than usual - from 5 to 10 minutes. At this time, the Android or Mi logo may be displayed on the screen. Do not interrupt this process and do not remove the battery (if it is removable), as the system files are being configured.
💡
Hard Reset fixes software errors, but does not solve problems with corrupted file system or "broken" memory sectors.
Addressing memory and overflow problems
One of the hidden reasons Redmi 8 is constantly rebooting is a critical overflow of internal memory. Android requires free space to create temporary files and work the background processes correctly. If the memory is full by 98-100%, the system can enter a reboot cycle, since it has nowhere to deploy the necessary services to run.
The table below shows the main symptoms of memory deficiency and the corresponding actions:
| Symptoms. | Possible cause | Action. |
|---|---|---|
| The phone turns off when the camera starts. | Lack of RAM and memory for buffer | Clear the application cache in safe mode |
| The endless screensaver of Android | The system section is full of logs | Execute Wipe Data through Recovery |
| Self-involved restarts in games | Overheating and trottling due to lack of resources | Remove heavy apps and games |
| Slow work and hanging up | Fragmentation of the file system | Make a backup and a full reset |
If your phone still loads to your desktop, delete the files immediately. Move the photos and videos to your computer or cloud storage. Remove apps you don't use. Pay special attention to messengers like Telegram or WhatsApp, which can take up gigabytes of cache space. Clearing the cache of these apps through settings can free up a few gigabytes, which will restore the system's stability.
💡
Use the Cleanup feature in Xiaomi’s built-in Security app, which automatically finds garbage, large files and duplicates that are safe for the system.
Fastboot and Mi Flash Tool
If the software reset didn't work, it means the system files of the operating system are damaged, and in this case, you need a complete firmware reinstallation. For Xiaomi Redmi 8 (codenamed olive or olivelite), you can do this using the Mi Flash Tool utility on your computer, USB-cable and pre-downloaded official firmware in Fastboot format (archive with.tgz extension).
First, you need to put your smartphone in Fastboot mode. Turn it off completely. Then press the volume button and hold it, plug it in. USB-The phone screen should show a logo of a hare in a hat-eared android repairer, with the inscription FASTBOOT. If the phone is in this mode, then the bootloader and base partitions are intact, and the chances of recovery are high.
Firmware instructions:
1. Unpack the firmware archive in the root of the C disk (the path should not contain Cyrillic).
2. Launch the Mi Flash Tool on behalf of the administrator.
3. Press the "Refresh" button so that the program sees the device.
4. Select the option "Clean all" in the lower right corner.
5. Press Flash and wait until the process is over (green bar).⚠️ Note: When flashing through Fastboot, all data will be permanently deleted. Make sure you use the firmware specifically for your model (Redmi 8 has two versions: Global and India, firmware is not interchangeable).
The firmware process can take 100 to 300 seconds. Once successful, the phone will automatically restart. The first load will be long. If there is an error in the process (red bar in the program), try replacing it. USB-The problem is often a poor contact or a lack of power supply. USB.

When repairs are needed in the service center
There are a number of situations where software treatments are useless and require the services of a qualified engineer. If after flashing the official stable version of the software, the problem of cyclic reboot persists, most likely it is a problem of hardware. The most common reason in Redmi 8 is a CPU or memory dump due to overheating or impact, and the power controller failure.
Diagnostics in the service include checking the current consumption on the laboratory power supply. If the phone consumes short circuit current (SK) or, conversely, does not consume it at all when trying to turn on, this indicates a malfunction of the components of the motherboard. Also a frequent problem is battery degradation: if it does not keep the voltage under load, the phone will go into reboot immediately when trying to start energy-intensive processes.
💡
If the phone is warming up in the camera or processor area even when it's off when charging, it's a sign of a short circuit on the board. It's dangerous to operate such a device!
Don't ignore the charging connector issues. The Redmi 8 uses a USB Type-C port that wobbles over time. Oxidation of contacts or poor contact can lead to voltage surges that the system perceives as a signal to reboot. Replacing the connector is a low-cost and fast procedure that can solve the problem of floating reboots.
