Redmi 9: how to restart the Xiaomi smartphone without the risk of damaging the system

Your Xiaomi Redmi 9 suddenly stopped responding to touch, the screen stopped in one image and the buttons didn’t work? This is a situation familiar to many owners of budget smartphones, especially after prolonged use or installation of “heavy” applications. In 80% of cases, the problem is solved by a simple reboot, but it is important to do it correctly – so as not to aggravate the breakdown or lose data.

In this article, we will discuss all the working ways to reboot for Redmi 9 (including the Redmi 9A/9C/9T modifications), and when the device:

• 📱 It's on the logo. MIUI or download animation;
• 🔄 Does not respond to touch and power button;
• 🔋 Discharged "to zero" and does not turn on after charging;
• 🤖 It makes a mistake: "The system is not responding».

1. Forced reset: when and how to do

If Redmi 9 is completely frozen and unresponsive, try hardware reboot first, a method that is data-safe and works even in critical system failures.

For the Redmi 9 (and all versions based on the MediaTek Helio G35/G80), use the combination:

The smartphone should vibrate and reboot. If it doesn't,

• 🔋 Check the battery charge (plug in for 5-10 minutes);
• 🔌 Try another charger or cable;
• 🔄 Repeat the combination by holding the buttons for up to 20 seconds (maximum time for forced power outages).

💡

If the smartphone vibrates, but the screen is still black, the problem may be the backlight of the display. Try to shine a flashlight on the screen at an angle: sometimes the image is visible in bright light.

⚠️ Warning: Don't use needles or sharp objects to press buttons! on Redmi 9, the power and volume buttons are located in one block - damage them easily.

2. Soft Reset: Reboot via menu (if the smartphone is partially working)

How to log in to Recovery:

1. Turn off your smartphone (forced if it doesn’t react)
2. Hold the power button + increase the volume until the Mi logo appears.
3. Release the power button, but keep the volume + until you see the menu.

4.Reboot via Fastboot (for power users)

If Redmi 9 doesn't boot even to Recovery, then Fastboot mode remains, allowing you to reflash the device or perform diagnostics via PC, which requires ADB/Fastboot drivers installed and basic command line knowledge.

How to log in to Fastboot:

1. Turn off the smartphone.


2 Hold the power button + volume down until the screen with the rabbit and the words Fastboot appears.




3. Connect to the PC via USB.

• 📱 Fastboot Reboot Recovery – Reboot Recovery;
• 🔧 fastboot devices – connection check (serial number must be displayed).

• 🔋 Worn-out battery (if the smartphone turns off at 20-30%);
• 🤖 Older scaling (especially relevant to the MIUI 12 and below);
• 🎮 Background processes (games, messengers, optimizers).

Preventive measures:

1. Clean the cache once a month through Settings → Storage → Cleanup;
2. Update your firmware (the current version of MIUI is optimized for Redmi 9)
3. Turn off the autoload of unnecessary applications in Settings → Battery → Autostart;
4. Use a memory card to store photos/video (but not for apps!).

6.When a reboot doesn't help: signs of hardware breakdown

If none of these methods worked, the problem could be iron.

• 🔥 The smartphone is overheating even in simple;
• 🔋 The battery is discharged in a few hours without using;
• 📵 No response to charging (indicator not burning);
• 💥 Artifacts appear on the screen (stripes, flickering).

In these cases, self-rebooting is pointless - a diagnosis is required at a service center.
