How to Make a Deep Xiaomi Reboot: The Complete Guide

Modern Xiaomi and Redmi smartphones are complex computing devices that require periodic cleanups of system memory, running MIUI or HyperOS. Sometimes a standard power outage or simple reboot is not enough to fix software failures, interface freezes or incorrect operation of individual communication modules. In such cases, users require a more radical approach, often called “deep reboot”, which involves completely updating the state of all system processes and cleaning temporary files.

Understanding the difference between a conventional shutdown and a deep reset is critical for Xiaomi appliance owners, as improperly applying hard-core techniques can lead to data loss. Deep reboot can range from simply resetting through an engineering menu to completely clearing the user partition through Recovery mode. It is important to be clear about what procedure you plan to perform, as the consequences are diametrically opposite, from safely updating the cache to completely removing all photos and contacts.

In this article, we will take a look at all the available deep reboot techniques, from secure software to enforcement to bricks. We will look at the engineering menu, physical navigation buttons, and automatic system recovery tools. Follow the instructions carefully to ensure that your device’s software is not damaged.

Difference Between a Normal and Deep System Reboot

The usual reboot that most users do every day is to shut down the Android operating system and then run all services anew, affecting the user layer and core system services, but often leaving the low-level drivers and cache of the radio module unchanged, as a result, accumulated memory errors may not be eliminated, and the phone will continue to work unstablely.

Deep reboot, in turn, involves more aggressive interference with the hardware and software, which can be a complete power reset of all controllers, cleaning up.Dalvik/ART Only a deep reset through Recovery Mode can fix errors that result from a failed update or damage to system files.

There is also the notion of a “cold reboot” where the device completely shuts down and the capacitors on the board run out. For modern Xiaomi smartphones with non-removable batteries, this is accomplished through prolonged button retention or special commands in the engineering menu. Understanding these nuances will help you choose the right method of solving your problem.

⚠️ Note: Do not confuse deep reboot with Factory Reset.Some of the methods described below can result in your data being completely deleted without the ability to recover.

Software reset via engineering menu

One of the safest and most effective ways to perform a deep reboot without losing personal data is to use the Android engineering menu, which allows you to send direct commands to the operating system without skipping the standard interface buttons. To enter it, a universal code is used, which works on most Xiaomi, Redmi and other devices. POCO.

To start the procedure, open the Phone app and dial the combination ##64663## or ##3646633## (code may vary depending on the version of MIUI). If the menu opens, go to the Common or Debug section where you can find options for testing and rebooting modules. However, a more versatile method is to enter the code ##7780###, which initiates a reset, but on new versions of Android can simply redirect to the standard recovery menu.

A more advanced method for deep rebooting the radio and network is using code ##4636##. Once in the Phone Information menu, you can see usage statistics and perform a network reset, which often solves problems with signal loss or Wi-Fi.

Reset buttons (Hard Reset Power)

If software methods are not available due to a hung screen or unresponsive interface, the only option is hardware reset. Xiaomi smartphones have a mechanism to simulate battery recovery. This requires you to pinch and hold the power button for a long time, usually from 10 to 20 seconds.

In more complex cases, when a device does not respond to a single tap, a combination of buttons is required. Press the Volume Up and the power button simultaneously. Hold them until the Mi or Redmi logo appears. This method forces the power controller to perform a cycle of shutdown and on, ignoring the software locks.

There's also a specific combination to enter recovery mode, which is often used as the first step to deep reset. Hold Volume Up + Power and hold until you vibrate. If you're on a menu with black background and English text, you're in Recovery Mode. You can already choose download options here.

💡

If the phone vibrates but the screen is black, try plugging it into the charger and repeating the button combination. Sometimes a low charge blocks the system from starting.

Full reset via Recovery Mode

Recovery mode is a separate mini-partition in the smartphone memory designed to service the system. This is where the deepest reboot is performed, cleaning the user partition. Before entering, make sure that the battery is at least 50%, as the process can take time.

Turn off the device completely to enter. Then press the Volume Up button and press the Power button without letting it go. Hold both buttons until the logo appears, then release Power, continuing to hold the Volume Up. The menu is navigated with volume buttons (up/down), and the power button selects.

You need to select Wipe Data. In the submenu that opens, select Wipe All Data. The system will warn you of data loss — confirm the action by selecting Confirm. After the process, which takes a few minutes, select Back to Main Menu, then Reboot and Reboot to System. The device will reboot as new.

⚠️ Warning: After resetting via Recovery, the device will work protection FRP (Factory Reset Protection. You'll need to enter your username and password from a Google account or a Mi Account that was previously synced, and without that, your phone will become a brick and mortar».

Using Fastboot to Flash Up

Fastboot mode provides access to a low-level boot interface that is used to run memory partitions directly from your computer, the deepest level of interaction with Xiaomi software available to the average user, and is needed if the system is damaged so much that it does not even boot into Recovery.

To enter this mode, press the Volume Down and Power buttons on the device turned off. The image of a hare repairing an android will appear on the screen and the inscription FASTBOOT. To work in this mode, the Mi Flash Tool utility and the corresponding Xiaomi drivers must be installed on the computer.

The Fastboot recovery process requires you to download the full firmware (ROM) for your particular model. The firmware file must be in.tgz (Windows) and unpacked. Mi Flash selects the file path and firmware mode: clean all (complete clean) or save user data (trying to save data, doesn't always work).

💡

Fastboot is "heavy artillery." Use it only if other methods have failed and you are confident in your actions, as a mistake in choosing a firmware can put the device out of action.

Frequent problems after a deep reboot

After performing a deep reset or flashing procedure, the device may not behave as expected. The normal situation is the first download, which lasts much longer than usual - from 5 to 15 minutes, during which time the system optimizes applications and rebuilds the file system, so do not try to interrupt the process.

One common problem is a cyclic bootloop, where the phone constantly displays the logo and shuts down again, which can indicate damage to the system partition or driver conflict, often by logging back in to Recovery and executing the Wipe Cache command (if available), or completely flashing through Fastboot.

Users also often face activation blocking. If after a reset, the phone requires a password from a Mi Account and you do not remember it, access restoration is possible only through the official Xiaomi website if there is a purchase check.

⚠️ Warning: If the phone warms up in the camera or processor area after reset and discharges quickly in standby mode, there may be file indexing or a large number of applications being updated in the background.
