How to Reboot Xiaomi Redmi 4X: 5 Ways to Work

Introduction: When to Reboot and Why Redmi 4X Can Hang

Xiaomi Redmi 4X (codenamed Santoni) is sometimes rebooted, despite its reliability, due to software failures following a MIUI update, overheating of the Snapdragon 435 processor, or application conflicts, such as many users encounter a black screen after installing custom firmware or improperly shutting down the battery.

Unlike modern fastboot-protected models, the Redmi 4X has a simpler recovery architecture that makes restarting easier. However, incorrect actions (such as interrupting the upgrade process) can lead to a “brick” – a state where the device does not turn on even after charging. In this article, we will discuss all the safe ways to reboot, including hidden functions of the engineering menu.

The Redmi 4X has no physical Bixby or Assistant button, which makes it easier to reset key combinations, but it is sensitive to deep battery discharge (below 3.2V), which can block standard on-board methods. If your smartphone does not respond to charging, check the voltage with a multimeter first or use a frog to force you to recharge.

1. Standard reboot (soft restart)

The safest method that doesn’t affect user data is suitable if the smartphone responds to touch, but it doesn’t work smoothly (e.g., slows down the interface or doesn’t open apps).

Instructions:

• 📱 Hold the power button (located on the right end) for 3-5 seconds until the off menu appears.
• 🔄 In the menu, select Reboot (or Restart in English firmware).
• ⏳ Wait until the process is complete (usually takes 20 to 40 seconds).

If the menu doesn't appear, try Power + Volume up (hold 8-10 seconds). This simulates a "hard" reboot, but without losing data. Importantly, on a Redmi 4X with an unlocked bootloader, this combination can run a Fastboot instead of a reboot.

⚠️ Note: If after a soft restart, the smartphone loads longer 2 minutes, this may indicate damage to the partition /system. In this case, you will need to flash through MiFlash.

Save open documents and browser tabs

Close the background applications (especially games)

Connect to charging if the battery level is below 15%

Make sure that SIM-The card is inserted correctly (sometimes due to poor contact)

2. Forced reset (hard reset)

Used when the smartphone is completely frozen (“brick”), does not respond to touch or power button. This method does not erase data, but can interrupt background processes (for example, downloading files).

Step-by-step:

1. Hold the power button + volume down at the same time.
2. Hold for at least 12 seconds until the screen goes out and vibration starts.
3. Release the buttons – the device will automatically restart.

On the Redmi 4X with MIUI 10+ firmware, this combination can trigger Recovery Mode. If you see the Mi Bunny logo with Android on your back, you're in the recovery menu.

• 🔧 Choose Reboot. → Reboot to System (manage volume buttons, confirmation - power button).
• 🔋 If the battery is discharged below 5%, the smartphone may not turn on – connect charging for 10-15 minutes.

3.Reboot via Recovery Mode

This method is useful if the smartphone boots only to the Mi logo or cyclically restarts (bootloop). Recovery on Redmi 4X comes in two types: stock (from Xiaomi) and custom (TWRP).

How to log in to Recovery:

• 🔌 Turn off your smartphone (hold the power button for 15 seconds).
• 🔄 Keep your food on. + Loudness up until the menu appears.

Further action:

⚠️ Warning: In Mi Recovery, Wipe All Data will completely reset your smartphone to factory settings! Use it only if you are sure you have made a backup through Mi Cloud or Google Account.

4. Reboot through the engineering menu (#4636##)

The hidden Testing menu allows you to restart your smartphone without physical buttons. This method works even if the touchscreen does not respond to touch (assuming the device is on).

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. Select Phone Information (or Phone Information) from the menu.
3. Scroll down and click Reboot (or Reboot).

Advantages of the method:

• 🔧 No need to press physical buttons.
• 📊 The current version of Baseband and IMEI (useful for diagnosing communication problems).
• 🔋 Allows you to check the status of the battery (Battery Information section).

Limitations:

• ❌ Does not work if the smartphone is turned off or in bootloop state.
• ❌ On some firmware (for example, MIUI 12.5+) The combination may be blocked.

💡

If the engineering menu doesn't open, try entering the combination through Google Play's Secret Codes app. MIUI straight USSD-request.

5.Reboot via ADB and Fastboot (for advanced)

If the smartphone is connected to a PC but does not respond to standard methods, you can use Android Debug Bridge (ADB) or Fastboot. This is true for devices with unlocked bootloader or root rights.

Method 1: Through ADB (if the smartphone is on but hovers):

adb devices


adb shell reboot

Method 2: Through Fastboot (if the smartphone is in bootloader mode):

fastboot devices


fastboot reboot

Method 3: Forced Reboot in Recovery:

fastboot reboot recovery

Requirements:

• 🖥️ Installed Mi drivers USB Driver and ADB Tools (download from Xiaomi website or via the SDK Platform Tools).
• 🔌 Included debugging by USB in the developer settings (Settings) → The phone. → Version. MIUI — press 7 times).
• 🔓 Unlocked bootloader (for fastboot commands).

⚠️ Warning: The fastboot oem edl command will put the device into Emergency Download Mode, which can lead to data loss if MiFlash is used incorrectly.

💡

The fastboot reboot-bootloader team restarts the smartphone back to fastboot, which is useful for cyclical firmware without turning off the cable.

6.Diagnostics of problems after reboot

If the smartphone is restarted, but is unstable, check:

For a deep diagnosis, use:

• 📊 CPU-Z — hardware-test.
• 🔋 AccuBattery – Analysis of the battery status.
• 🛠️ Mi PC Suite – Xiaomi’s official software recovery tool.
