How to reboot Xiaomi Redmi 12: a complete guide to restart

Owning a modern smartphone like the Xiaomi Redmi 12 involves encountering situations where the device stops responding to commands: the screen goes out or, conversely, hangs on a static image, applications stop opening, and touch input is completely ignored, at which point the only right decision is to perform a forced or regular restart of the system to restore normal operation of the software shell.

However, not all users know that there are several ways to reanimate the gadget depending on the severity of the freeze. Standard shutdown through the menu may not be available if the interface is completely blocked by a process that takes up all the resources of the processor, which is why it is important to use methods that work even when the display does not respond to touch using physical control buttons.

In this article, we will discuss in detail the algorithms of actions for various scenarios, from a scheduled update to an emergency rescue of the “brick”, you will learn how to correctly combine the button clamping, how long you need to wait for the device to react, and what you absolutely cannot do during the power reset process so as not to damage the MIUI or HyperOS file system.

Staff reboot through the settings menu

The safest and most appropriate way to complete Redmi 12 is to use an embedded programming interface, which ensures that all active processes are completed correctly and system files are closed without writing errors, and use this option if the screen is touch-sensitive and you can freely navigate the desktop.

To do this, unlock your device and find the Settings icon, usually presented as a gear. In the menu that opens, scroll down to the bottom of the list, where the About Phone section or Advanced Settings section is located, depending on the version of the firmware installed, where you will find a large Reboot button, clicking on which initiates a regular off and on cycle.

An alternative path that works on most versions of the shell involves using the control panel. Swipe from top to bottom to open the notification curtain, and find the power icon in the upper right corner of the interface. A menu will appear with three options: turn off, restart and air mode. Select the Reboot option will start a safe restart of the system.

⚠️ Warning: If after pressing the reboot button the screen is turned off, but the device does not turn back on during the 2-3 Sometimes the process of updating system components takes longer than usual.

There is also a quick way available in some MIUI configurations: Try to press the volume button and the power button simultaneously on the locked screen. If the function is activated in the settings, the reboot mode selection menu will appear. This is convenient when the display is not on, but the phone responds to physical buttons.

Forced reset (Hard Reset buttons)

When the software part of Xiaomi Redmi 12 is completely blocked, it requires a hard reboot method, which ignores the operating system state and sends a signal directly to the power controller, forcibly breaking the circuit and restarting the bootloader, analogous to removing the battery, which in modern monoblocks is non-removable.

To do this, you need to find the side of the device, where the audio keys and the fingerprint scanner are located, combined with the on button. The key here is the duration and combination of the pressing, you need to press the power button and hold it continuously for a long time, ignoring any vibrations or logo appearances.

• 🔘 Press the power button and hold it near. 10-15 seconds until the screen goes out.
• 🔘 If the screen is out, but the phone is not vibrating, keep holding the button. 5-10 Seconds before the Redmi or Mi logo appears.
• 🔘 In some cases, simultaneous clamping of the power buttons and Volume Up on 15-20 seconds.
• 🔘 Release the buttons only after you feel a vibration or see the manufacturer’s logo.

It is important to understand that this method does not delete your personal data, photos or contacts; it only cuts the power of the processor, resetting RAM. All files stored in internal memory remain intact, since this process does not affect the user’s storage parts.

Reboot with Recovery Mode

If standard methods and long-term button retention fail, or if the system suggests you choose boot mode, you may end up in the Recovery menu.This is a special diagnostic mode built into the device's memory that allows you to perform maintenance at a low level, bypassing the main Android operating system.

You can get into this menu by turning off your phone completely, then holding the Power and Volume Up buttons together. Hold them until the Mi logo appears, then release the power button, but keep the volume up until the menu with a black or grey background appears. Navigation is done with volume buttons (up-down), and selection is done with the power button.

In the options list, often called Main Menu, you're interested in Reboot. When you select it, you'll see a submenu where you need to confirm Reboot to System. This is a command for a normal reboot. There's also a Reboot to bootloader option that you need to flash, but in this case, it's not required.

⚠️ Warning: In the Recovery menu, never select Wipe Data or Factory Reset if your goal was simply to reboot.These commands will permanently delete all your files, accounts and settings, returning the phone to factory status.

What to do if Redmi 12 doesn’t respond to buttons

There are critical situations where the Redmi 12 does not respond to touch, button clamping, or charger plugging.The screen stays black, the LED lights don't burn, and it seems like the device is dead. In most cases, it's not a breakdown of iron, but a deep "sleep" of the power controller or a full battery discharge.

The first step in this situation is to connect the smartphone to the original charger and cable. Leave the device to charge for at least 30-40 minutes, even if there is no indication on the screen. Sometimes, to activate the power chain, you need to dial a minimum energy threshold, after which the phone will “revive” and show the charging logo.

If 40 No reaction time, try the cyclic pressing method. Press the power button quickly. 10-15 once in a row, and then try to pin it on 20-30 This technique sometimes helps to "unstrain" the controller if it is getting stuck in a standby state, and it is also worth checking whether the button itself has blocked inside the case due to dirt or moisture.

In rare cases, the problem lies in the software failure of the bootloader. If a QDLoader 9008 device appears in Windows Device Manager when you connect to a computer, this means that the phone has entered emergency mode, exiting it only through specialized firmware, which requires the intervention of specialists.

Automatic reboot on schedule

Modern versions of the MIUI and HyperOS shell offer a convenient automatic reboot function, which is an excellent preventive tool for maintaining the stability of the system, and periodic resetting of cache and processes in the background avoids the accumulation of errors and “severe” interface behavior.

To set up this feature, go to Settings, then select Advanced Settings (or Additional) and look for Scheduled Power On/Off, where you can set the time when your phone will turn off and turn on, for example, at 3 a.m. when you sleep.

• 🕒 Set the on and off time at intervals in 1-2 minute.
• 📅 Select the days of the week when the function will be active (for example, daily or only on weekends).
• 🔔 Make sure alarms and important notifications are not missed during the reset window.

Using automatic reboot is especially useful for users who don’t like to manually reboot their phones often, which helps the system “dispose” accumulated debris in RAM and update system services, which has a positive effect on processor speed and sensor response time.

💡

For maximum efficiency, set up automatic reboot for a time when the phone is guaranteed not to be used, for example, from 04:00 to 04:02. This will ensure a fresh start to the system by the time you wake up.

Frequent problems after rebooting

Once a successful reboot is completed, users may encounter a number of standard phenomena that are not signs of a breakdown, and understanding these processes will help avoid unnecessary panic and repeated missteps with the device, and the system will always go through the initial optimization phase after restart.

The first thing you might notice is that the phone is warmer than normal and the battery is used up faster, and that's normal, with background services, widgets and apps running again, indexing files and syncing data to the cloud, which typically takes 15 minutes to an hour of active use.

It may also be temporarily unavailable or slow Internet, and the communication module takes time to register with the operator's network and switch between towers (2G/3G/4G/5G). If the network does not appear through 5-10 minutes, try to turn on and off the flight mode through Settings → SIM-maps and mobile networks.

⚠️ Warning: If the phone is constantly showing the logo after a reboot and switches off again (cyclic reboot), this is a sign of damage to system files. In this case, a simple restart will not help - you will need a factory reset or flashing.
