How to Reboot Xiaomi Redmi 4: From Basic Restart to Emergency Reset

Xiaomi Redmi 4, released in 2016, remains a popular budget smartphone due to its robust hardware and flexible MIUI firmware. However, even this centenarian has crashes: sudden hanging, black screen after updating or endless boot. 80% of the time the problem is solved by a correct reboot - but not all users know that there are at least five, and each method works in its situation.

This article is not about the banal hold of the power button. We will examine all the ways of restarting from standard to engineering, including rebooting through ADB and hidden menu Fastboot. And also find out why Redmi 4 can not respond to buttons, and what to do if after a restart the phone requires a Mi Account password. The instructions are relevant for all modifications: Redmi 4 Pro, Redmi 4 Prime and Redmi 4A.

1. Standard Reboot: When a Smartphone Reacts to Commands

If the Redmi 4 screen is working and the system is responding to touch (albeit with a delay), use a software restart. This is the most secure method, without affecting data and settings.

Launching methods:

• 📱 Through the power menu: hold the power button for 2-3 seconds until the dialog window appears).
• 🔄 Through the notification bar: swipe down from the top edge of the screen, find the icon ⚙️ Settings → Additionally. → Reboot.
• 🤖 Voice command (if Google Assistant is enabled): say, OK, Google, restart your smartphone».

⚠️ Warning: If the screen goes out after clicking "Reset" but the Xiaomi logo doesn't appear for more than 5 minutes, this is a sign of a damaged bootloader.

Standard reboot helps in cases of:

• 🐢 Slow work due to background software (for example, after installing heavy games).
• 📶 Network problems (does not catch Wi-Fi or mobile Internet).
• 🔊 Disappearance of sound or microphone.

Forced reboot: if the screen is frozen or unresponsive

When the smartphone freezes completely (it doesn’t respond to touch, volume and power buttons), a hardware reset is required, which simulates battery extraction but doesn’t erase data.

Instructions for Redmi 4:

1. Hold the Power button for 10-15 seconds until the screen goes out.

On Redmi 4 with non-original firmware, a forced restart can only work after holding the Power + Volume buttons up for 20 seconds.

Reasons for the forced reset:

• 🖥️ Infinite download animation (bootloop).
• 🎮 Hanging in a game or application (for example, PUBG Mobile or Genshin Impact).
• 🔋 Black screen after charging connection.

Turn off the charger (if connected)

Check if the volume button is pressed (may block restart)

Make sure the battery is at least 5% charged.

Wait 1 minute after switching off before re-energizing-->

3 Hard Reset: When the reset doesn't help

If Redmi 4 is turned on but does not load beyond the logo or restarts cyclically, it will require a reset via Recovery Mode, which deletes all data (photos, contacts, applications), but restores the system to work.

Step-by-step:

1. Turn off the phone (if it doesn’t respond, make a forced restart from Section 2).
2. Press Volume Up + Power and hold for 10-15 seconds until the Mi Recovery logo appears.
3. From the Recovery menu, select Wipe Data → Wipe All Data (use volume buttons for navigation, Power buttons for confirmation).
4. After reset, go back to the main menu and select Reboot → Reboot to System.

⚠️ Note: if after resetting the phone requires the entry of the Mi Account password, and you do not remember it, you will need an official unlock through the Xiaomi service center.

4 Safe Mode: Diagnosing problem applications

If Redmi 4 is turned on but is unstable (spontaneously restarts, slows down, issues errors), the cause may be a conflict application. Safe mode loads the system without third-party software, allowing you to identify the culprit.

How to start Safe Mode:

1. Turn off the phone.
2. Hold the Power button until the Mi logo appears.
3. Once the logo disappears, immediately pinch and hold Volume down until the download is complete.
4. In the lower left corner of the screen will appear the inscription “Safe mode”.

In safe mode:

• 🔍 Check if the glitches have gone away. If so, there's a problem in one of the apps installed.
• 🗑️ Remove recently installed programs (especially optimizers, antiviruses, or launchers).
• 🔄 Restart your phone in normal mode.

⚠️ Warning: Safe Mode has disabled all Google services and background processes. Do not try to update apps or change system settings - this may cause a failure.

💡

If the phone is stable in Safe Mode but it is buggy again after a normal boot, use the Settings → Applications → Truthfulness feature (in MIUI 12+) to show which programs consume the most resources.

5.Reboot via Fastboot: for power users

When Redmi 4 doesn't boot even to Recovery, there's a last chance, the Fastboot mode, which lets you reflash the device or reset the settings through your computer, USB-cable and installed drivers Mi Flash Tool.

Step-by-step:

1. Turn off the phone.
2. Press Volume Down + Power and hold until the screen with Fastboot (the Android robot with an open case) appears.
3. Connect Redmi 4 to your PC via USB.
4. Download the official firmware for your model (e.g. Redmi 4 Prime - Latest Global Stable ROM).
5. Unpack the firmware and use the Mi Flash Tool to select Clean All mode (full reset).

On Redmi 4 with a locked bootloader, flashing through Fastboot is only possible after the official unlocker from Xiaomi (the process takes up to 720 hours of waiting!).

Advantages of the method:

• 🛠️ Allows you to install custom firmware (for example, LineageOS).
• 🔄 Solves problems with bootloop (cyclic reboot).

💡

Fastboot flashing is the only way to bring Redmi 4 back to life if it doesn't respond to buttons and loads into Recovery. But without a backup, it won't be possible to restore it.

6. Alternative methods: ADB, engineering menu and service codes

For advanced users, there are three other reboot methods that are rarely mentioned in standard instructions:

1.Across ADB (Android Debug Bridge)

If the phone is enabled debugging over USB, you can send a restart command from the PC:

adb shell reboot

For a hard reboot:

adb shell reboot recovery

2. Engineering menu (#4636##)

Enter the code on the phone keyboard, go to Phone Information, and select Reboot. This method works even when the screen is locked (if known). PIN-code).

3. Service code for resetting

Dial it ##7780## — This will start a soft reset (remove only settings without affecting files *2767*3855#, But be careful: this code erases everything, including the data on the SD-map!

⚠️ Note: Service codes may not work on custom firmware or in regions with limited functionality (e.g. firmware for China).

Even a simple reboot can go wrong, except for the nuances of Redmi 4:
