Xiaomi Redmi 4X is getting stuck in Fastboot: a complete recovery guide

When your Xiaomi Redmi 4X suddenly freezes, displaying the logo of a hare repairing an android, or the inscription FASTBOOT, can cause panic in any owner. This is a standard low-level access mode designed for engineers and advanced users, but you can get there by accident, for example, by holding the wrong button when you turn on. Most often, the device just waits for a connection to the computer for further manipulation, but if the phone does not respond to presses and does not leave this state on its own, you need to act decisively.

In most cases, the problem is solved by a simple reboot, but there are scenarios where a software failure blocks the normal shutdown. Understanding the nature of this mode will help you avoid unnecessary worries and, more importantly, prevent possible data loss. Below we will discuss all the available methods, from simple to complex, that are guaranteed to bring the Redmi 4X back to life.

Reasons for getting into Fastboot mode and diagnosis

Xiaomi’s Fastboot mode is activated while simultaneously pressing the volume down and power button while the device is turned on. Often this happens by accident when the phone is lying in a tight case or in a pocket where the buttons are mechanically impacted. However, if the Redmi 4X is getting stuck in this mode on its own, without your involvement, it can signal more serious software or hardware issues.

One of the common reasons is a failed system update or interruption of the firmware installation process, in which case the bootloader cannot find the correct files to start the operating system and goes into emergency command standby mode. Also consider the possibility of damaging system files after installing informal assemblies or root rights. Diagnosis begins with assessing the reaction of the device: whether it vibrates, whether the case warms, whether the brightness of the logo backlight changes.

⚠️ Note: If the power cable is connected to the got stuck device, the screen does not light up and no charging indication appears, it may be that the problem lies in the deep discharge of the battery or a malfunction of the power controller, and not in the software failure.

For accurate diagnosis, connect the phone to the computer through USB-If in Windows Device Manager (Ports section (COM and LPT) Android or Qualcomm device appears HS-USB QDLoader or Android Bootloader Interface, so there is a connection to the processor and software recovery is likely. The lack of a computer reaction may indicate that the phone is completely "dead" or requires a replacement of the plume / connector.

Basic methods of exit without data loss

The easiest and safest way to do this is to force a 90 percent reboot, so you don't need a computer, you don't need special cables, you don't need complex software, all you need is to physically interact with the smartphone's control buttons, and it doesn't affect user data, photos, or contacts, because it just restarts the download cycle.

To do this, you need to hold the Power button for a long time. It usually takes 10 to 20 seconds. At that point, the phone can vibrate, the screen can go out and light up again. The key here is to keep the button on, even if it seems like nothing is happening. Once the screen goes out, release the button immediately and wait for the Mi logo to appear.

If the standard power button holding didn't work and the Redmi 4X is back on Fastboot, try the combined method. Press the Volume Up and Power buttons at the same time. Hold them until the Recovery menu (usually a black menu with a few lines) appears. If the menu appears, select Reboot and confirm the Reboot to System action.

⚠️ Warning: Do not confuse Recovery mode with Fastboot. Recovery controls volume buttons and the power button confirms the choice. Random choice of Wipe Data will result in the complete deletion of all files.

Using ADB to Forced Restart

If physical buttons don't respond or the phone cycles back into Fastboot mode, you can use the Android Debug Bridge (ADB) debugging tool, which requires a computer with drivers installed and platform tools installed, and allows you to send a software command to restart without passing physical buttons.

First, make sure that the computer has drivers for Xiaomi installed. Connect the phone with a cable to the PC. Open the command line (CMD) in the folder with the ADB tools. Enter the command to check the connection: adb devices. If the list shows a device with the status of unauthorized or fastboot, then the connection is established. To exit the bootloader mode, enter the command adb reboot.

adb reboot

In some cases, when a standard ADB does not see a device in Fastboot mode, it requires the use of a specific command for the fastboot protocol. Enter in the terminal: fastboot reboot. This is a direct order to the bootloader to leave the current mode and try to start the main system. If after executing the command, the screen goes out and the phone starts to boot, the problem is solved.

💡

If the fastboot reboot command fails, try reconnecting the USB cable to another port (preferably USB 2.0 at the back of the system unit) and repeat the command.

Complete flashing through the Mi Flash Tool

When the software failure is too deep and the phone can’t boot the operating system, the only way out is to completely flash it. For Redmi 4X (codenamed santoni), this process is well debugged. You’ll need the official Mi Flash Tool utility and a Fastboot firmware image (the archive should end in.zip, but inside contain.img and.bat files).

Before starting the procedure, make sure the battery is at least 50% charged. Download the firmware for your model (Global or China version should match the current or be newer). Unpack the archive to the root of the C disk so that the path does not contain Cyrillic. Launch Mi Flash on behalf of the administrator, press refresh and make sure that the device is identified.

Choose the path to unpacked firmware in the program. At the bottom of the Mi Flash window, be sure to select the Clean all option, as switching between versions or recovering from a crash requires a clean partition structure. Press the Flash button. The process will take 200 to 500 seconds. Once successfully completed, the phone will automatically restart.

Hardware reset and work with Recovery

If software methods fail, or if you suspect a setting conflict, you may need to reset to factory settings via the Recovery menu.This action will delete all user data, including contacts, messages and applications, so it should only be resorted to as a last resort.

Press Up Volume and Power at the same time. When the Mi logo appears, release the power button, but keep the volume up until the main menu appears. Here, the navigation is done with volume buttons (up/down), and the selection is made with a short press of the power button. Select the language (usually Chinese/English), then go to Wipe Data -> Wipe All Data.

• 🔹 Wipe Data: Completely removes the user partition.
• 🔹 Wipe All Data: Confirmation of Action (you need to press Yes).
• 🔹 Reboot: Reboot system after cleaning.

Once the reset is confirmed, the formatting process will begin, which will take a few seconds. Upon completion, the phone will suggest a reboot. The first start after the reset can last up to 5-10 minutes, as the system creates new configuration files. If the Redmi 4X freezes again after that, the problem is probably hardware-based.

⚠️ Warning: Once reset via Recovery, the phone will require you to enter a Google account or Mi Account that was synced earlier (FRP). Make sure you remember passwords.

💡

Hardware reset via Recovery is an extreme measure that eliminates software conflicts but permanently deletes the user’s personal data.

Hardware malfunctions and sticking button

The Redmi 4X is known for its reliability, but mechanical buttons wear out over time. If the volume button (which is responsible for entering the Fastboot) gets in, or has a damaged plume, the phone will constantly go into load mode every time it turns on, a common problem after falls or moisture.

To check, gently press the volume button area, if you feel no clear click or "wattiness," the mechanism may be broken, in some cases, neat tapping of the case or a slight flexion of the button (if the design allows) to unclose the contacts, but this is a temporary solution.

If software methods, including flashing, did not help and the phone continues to hang on the rabbit logo, and the button to the touch is working, there may be a malfunction of the motherboard, in particular, problems with the memory of the eMMC or the processor. In this situation, self-repair without soldering equipment and circuits is impossible, and you will need to contact a service center for diagnosis.

• 🔸 Check if the button is physically stuck.
• 🔸 Check the charger connector for oxidation.
• 🔸 Try to gently tap your finger on the back cover in the area of the buttons.

💡

If you suspect a button sticking (try) several times quickly press it in the off state to mechanically release the contact.
