When your Xiaomi Redmi Note 8T suddenly starts to reboot endlessly, it can take you by surprise: The screen goes out, the Mi logo appears, then the black screen again, and the cycle repeats over and over again.This phenomenon is technically called bootloop, and it indicates a serious glitch in the software or hardware of the device.
Most often, the cause is a failed system update, a crowded memory or a conflicting application. However, in some cases, the problem lies deeper — in the damage to system files or even in the malfunction of the power button. Cyclical reboot does not allow you to use the gadget normally, but in many cases it can be saved on your own without contacting the service.
In this article, we will discuss all possible causes and methods of solving the problem. We will consider both software recovery methods and hardware nuances specific to the Redmi Note 8T. Follow the instructions carefully to bring your smartphone back to life.
Diagnostics of the causes of an endless reboot
Before you start active action, you need to understand the nature of the failure. If the Redmi Note 8T goes into a cyclical reboot immediately after turning on, this may indicate damage to the bootloader or critical system files of Android. Hardware failure can also not be ruled out, especially if the device has suffered mechanical damage.
Often users will cause the problem by installing applications from unverified sources or obtaining Root rights. Any interference in the system partition increases the risk of errors. If you install custom recavators or modify firmware, the probability of failure increases many times.
⚠️ Warning: If the phone falls or gets wet before the problem starts, software methods may not help.
The state of the power button is particularly important. In the Redmi Note 8T, the power button is paired with the fingerprint scanner and is located on the side of the button, and the mechanical jamming of the button often causes the phone to perceive constant pressing as a command to reboot.
- 📱 Check if the switch button is physically stuck.
- 🔌 Make sure the charger is properly maintained and delivers a stable current.
- 💾 Remember if you have recently installed questionable applications.
- 🔄 Try to remember if the last system update was interrupted.
Understanding the root cause will help you choose the right algorithm for action, and if the problem occurred after the update, it's probably the firmware, and if the phone was just lying on the desk and starting to reboot, maybe it's the button or the battery.
Forced reset and safe mode
The easiest and often most effective way to stop chaotic processes is to perform a forced reboot, which disrupts current processes and forces the system to try to start again from scratch. For the Xiaomi Redmi Note 8T, the procedure is standard, but requires accuracy.
Press the power button and hold it for 10-15 seconds. The screen should go out, then the phone vibrates and tries to turn on. If the device continues to reboot, try a combination of power buttons and volume up, which can help you log into the recovery menu.
If the system does load but is not stable, you need to start Safe Mode, in which Android disables all third-party applications, leaving only the system, to determine whether a particular application is to blame for the reboot cycle.
💡
If the phone has time to show the desktop at least for a second, quickly press the off button in the menu, and then press and hold the "Disable" option on the screen to enter safe mode.
In Safe Mode, there's a sign in the corner of the screen, and if it's stable and it's not restarting, it's software that's the problem, and you'll need to delete the recently installed programs or clear the cache.
- 🛑 Press the power button on 10-15 drop-off.
- 🔇 Try logging into the Recovery menu by clamping the power and volume up.
- 🧹 In Safe Mode, remove the last installed applications.
- 📲 Check if the problem has disappeared after removing the suspicious software.
Using Recovery Mode for Resetting
If conventional methods don't work, you'll have to use a built-in recovery tool called Recovery Mode, which is a special environment that boots independently of the main operating system, and you can clear the cache or do a complete data reset.
To get into this menu on the Redmi Note 8T, turn off the phone (if it turns on, turn off via the menu, if it doesn't, wait for the discharge or use a combination of buttons). Then simultaneously press the Power and Volume Up buttons. Hold them until the Mi logo appears, then release the power, but keep the volume.
In the Recovery menu, you can navigate with volume buttons and choose with a power button. First of all, try clearing the cache, which will delete temporary files that may have been corrupted and caused crashes, but will not affect your personal data.
Wipe Data → Wipe All Data → Confirm → Back to Main Menu → RebootIf cleaning the cache doesn't work, the radical method is Wipe All Data, which will delete all photos, contacts and apps, returning the phone to factory status, and before doing so, make sure you have a backup if you can extract the data.
☑️ Preparing for resetting through Recovery
⚠️ Warning: After the Wipe All Data reset, the phone will require you to enter a password from a Google or Mi Account that was previously synced.
Smartphone firmware via Fastboot and Mi Flash
When the software failure is too deep and Recovery doesn't help, you need to completely reinstall the operating system. For the Xiaomi Redmi Note 8T, this is done via Fastboot mode. It's a low-level mode that allows you to write data directly to the device's memory.
For this you will need a computer with Windows OS, USB-You also need to download the official firmware for your model. It is important to download the version that corresponds to the region of the device, or the global version if you are ready to unlock the bootloader.
Enter Fastboot mode by pressing Power and Volume Down buttons on the phone turned off. Connect the device to your PC. In Mi Flash Tool, select the path to the unpacked firmware and press the Flash button.
| Parameter | Recovery ROM | Fastboot ROM |
|---|---|---|
| File size | ~2-3 GB | ~3-4 GB |
| Expansion | .zip | .tgz |
| Difficulty | Low. | Medium |
| Deletion of data | Optionally. | Definitely (Clean All) |
The firmware process can take anywhere from 5 to 15 minutes. Don't turn off the cable or turn off the computer at this time. Interrupting the process can cause the phone to stop responding to commands, turning into a brick.

Hardware problems: button and battery
If all software methods are exhausted and the Redmi Note 8T continues to reboot, the problem is the hardware. As mentioned earlier, the power button is a frequent culprit. Mechanical wear or moisture causes the contacts to close.
You can check this by tapping your finger on the button area carefully (without fanaticism) or pressing it slightly at different points. If the nature of the reboot changes, then the contact is broken, in which case you need to replace the plug of the power button in the service center.
Another is battery degradation, and if the battery can't deliver the current it needs at peak load (when the system starts), the voltage drops, and the phone goes into reboot, which is often the case on older devices.
- 🔋 Check the battery bloating (the back cover should not move away).
- 🔌 Try to start the phone from the charger network.
- 🔨 Carefully tap the body in the area of the power button.
- 🌡️ Pay attention to the heating of the bottom of the phone (processor area).
It's also worth checking the charging connector. Oxidation of the contacts can lead to voltage surges, which the system perceives as a signal to reset. Cleaning the connector with a toothbrush and alcohol sometimes works wonders.
💡
If the phone only reboots when moving or shaking, the problem is 99% hardware – the departure of the contacts of the plume or button.
Prevention and maintenance of the system
To avoid a repeat of bootloop on Xiaomi Redmi Note 8T, you must follow the rules of digital hygiene. Regularly clean the memory of the device, leaving 10-15% of free space. Overcrowded drive is one of the main reasons for the unstable operation of Android.
Don't install applications from unknown sources. Even if you need modified software, check it for viruses. Use the built-in Security antivirus that comes in the MIUI shell, it effectively blocks most threats.
Backup your important data regularly, sync your contacts and photos with Google or Mi Cloud, which will save your nerves and time if you need an emergency reset in the future.
⚠️ Warning: Do not interrupt the system update process. If the battery is dead during the upgrade, the phone may go into a cyclical reboot!
Timely firmware updates are also important. Xiaomi developers release security patches and bug fixes. However, it is better to update via the Settings menu → About phone → System update, not manually, if you are not an experienced user.
