When your Xiaomi smartphone suddenly stops responding to touch and endlessly reboots, throwing the user into a panic.The screen goes out, then the MI logo lights up again, the process is repeated endlessly, turning the once-trusty gadget into a useless piece of plastic and glass.This phenomenon, known as "bootloop," can be caused by both software failure and physical damage.
You don't have to take your device to a service center or look for a new phone, and in most cases, you can solve the problem yourself by acting consistently and in cold blood. MIUI, like any operating system, has hidden recovery mechanisms that you can access to fix critical boot errors.
Below, we’ll look at all the possible causes of cyclical reboot and suggest step-by-step algorithms for action, from simple forced reboot techniques to complex firmware manipulations through a computer, you’ll find a solution that will bring your gadget back to life.
Primary diagnosis and forced reset
The first thing you need to do is to rule out temporary operating system failure or freeze of individual processes. Often, the system simply cannot shut down background applications correctly, which causes an endless loop.
To do this, press the switch on and hold it for a while. 10-15 If that doesn't work, try a combination of power buttons and volume up, which forcely cuts off the power to the processor and restarts the system, bypassing standard shutdown procedures.
Attention: if the phone reacts to the presses with vibration, but the screen remains black, it may be the problem in the display, not the system, but if you see a logo that is replaced by a black screen, we continue to diagnose.
- 🔌 Turn off the charger and USB-cable, if they are connected.
- 🔘 Press the Power button 20 seconds before the logo appears.
- 📉 Make sure that the battery level is at least 15-20%.
- ❄️ Let the device cool if it gets too hot before freezing.
⚠️ Note: If after a forced reboot, the phone goes back into the cycle through 1-2 Do not repeat the procedure indefinitely, but it can completely drain the battery or damage the memory sectors.
Entering Recovery Mode and Cleaning Cache
If a simple reboot doesn't work, you need to go to Recovery Mode, which is a special diagnostic interface built into the phone's memory that allows you to control the system bypassing the main OS, and this is where most software bugs are solved.
To enter the Recovery menu, turn off the phone (if it turns on, wait for the black screen). Then simultaneously press the Volume Up and Power buttons. Hold them until the MI logo appears, then release the power button, but keep the volume up until the main menu appears.
Navigation in this menu is done with volume buttons (up/down), and the choice is confirmed by the power button. Find Wipe Data or Wipe Cache. Clearing the cache is safe for your data, it only deletes temporary files that may have been corrupted.
☑️ Recovery login algorithm
Once the cache is cleaned, select Reboot -> Reboot to System. If the phone boots normally, the problem has been resolved. If the cycle repeats, a more radical method will be required.
Full reset to factory settings (Hard Reset)
When cache cleaning is powerless, you have to go to extremes: Hard Reset completely erases all user data, returning the phone to the "out of the box" state, which eliminates errors in system files, update conflicts and malware.
From the Recovery menu, select Wipe Data, and the system will ask you to confirm the action, as all photos, contacts and apps will be permanently deleted, and the formatting process will begin after the confirmation, which can take several minutes.
Critically, if your phone has been blocked by a Find Device Mi Account, it will require you to enter a password from the account it was linked to after reset, and without that data, it will be impossible to unlock the phone.
| Action. | Data retention | Risk of data loss | Implementation time |
|---|---|---|---|
| Forced reset | Yes. | No. | 30 seconds |
| Cache Clearing (Wipe Cache) | Yes. | No. | 2 minutes. |
| Resetting settings (Wipe Data) | No. | 100% | 5-10 minutes |
| Flashing (Fastboot) | No. | 100% | 15-30 minute |
⚠️ Note: Before running Wipe Data, make sure you have access to your Google account and Mi Account. Otherwise, the device may become unusable due to security. FRP.

Fastboot mode and flashing the device
Even if a full reset didn't work, it means that the system partitions of the operating system are damaged, in which case you need to reinstall the firmware, and this uses the Fastboot mode, which allows you to interact with the phone directly through the computer.
To enter Fastboot, press the Volume Down and Power buttons simultaneously. The Fastboot logo should appear on the screen with a picture of a hare repairing an android. Connect the phone to the PC via the original one. USB-cable.
You will need the Mi Flash Tool and the official firmware for your model (file with extension.tgz). You should download the firmware only from proven resources, such as miui.com or xiaomirom.com, strictly observing the model compliance.

💡
Use it. USB-port 2.0 on the back of the computer motherboard. USB 3.0 and front ports of the case often fail when firmware, which leads to data transmission errors.
Hardware Causes and Problems with Memory
It's not always the software that's the problem. If the phone freezes on a reboot even after flashing, there's a high probability of hardware failure, and often the culprit is worn flash memory that stops reading data correctly.
Also, the cause may be oxidized contacts of the display plume or a bloated battery that is not able to produce the necessary current at peak times of loading the processor, in which case software methods are useless.
- 🔋 Battery Bloating: The Phone Can Shut Down Under Load.
- 💾 Memory wear: the appearance of artifacts on the screen or errors when installing applications.
- 🔌 Power Controller Problems: Chaotic Reboots for No Visible Reason.
- 🌡️ Overheating: Phone freezes if processor temperature reaches critical values.
If you suspect a hardware problem, further firmware attempts can only make the situation worse.
Prevention and safe use
To avoid a repeat of the situation, follow simple rules of operation: Do not allow the device to completely discharge to zero regularly, as this damages the battery chemistry and can cause voltage surges that are dangerous for the memory controller.
Install applications only from trusted sources, such as Google Play or GetApps. Third-party launchers and modified versions of system applications often cause MIUI to run unstable.
💡
Regular system updates and avoiding third-party firmware builds are the best protection against software crashes and freezes.
Periodically clean the phone’s storage, leaving 10-15% of free memory. The overflow drive runs slower and causes write errors more often, which eventually leads to cyclical reboots.
