Xiaomi Redmi 4 Pro (also known as Prada) can suddenly go into Fastboot mode, which often causes panic among inexperienced users. The image of a hare repairing an android appears on the screen and the inscription FASTBOOT in orange color. This state means that the smartphone is in low-level boot mode, designed for firmware or debugging, but not for normal use.
There are several reasons why the Redmi 4 Pro phone might have gotten stuck in this mode: an accidental pinch of buttons in your pocket, a crash when you update your system, a critical Android OS error, or even a hardware volume button problem. In most cases, the device is not physically damaged and can be brought back to life with simple software methods.
In this guide, we will take a look at all the proven ways to get out of the Fastboot state, from simply restarting to using specialized software. It is important to understand that forced power out when battery power is low can make it impossible to charge further, so follow the instructions consistently. Below are steps to restore normal operation of your gadget.
The reasons for the Fastboot mode on Redmi 4 Pro
Before you start resuscitation, you need to understand the nature of the problem. Fastboot mode is not a bug in the usual sense, but a diagnostic tool built into Qualcomm processors, which are used in the Redmi 4 Pro. It allows the computer to interact with the memory of the phone directly, bypassing the operating system.
Most often, this mode transition is due to mechanical action. The Volume Down button on this model is located on the side and can be accidentally pinched when carrying the phone in a tight case or pocket. If at this point the device was turned off or restarted, it interpreted this action as a command to enter firmware mode.
However, there are also programmatic prerequisites:
- 🐛 Failure when automatically updating the firmware MIUI, When the process is interrupted at a critical stage.
- 📱 Attempt to install custom Recovery or root rights with errors in scripts.
- 💾 Damage to the boot system partition after a failed experiment with ROM.
- 🔋 Critical battery discharge during system operation, causing incorrect process completion.
⚠️ Note: If the phone enters Fastboot mode cyclically immediately after turning on without your actions, this may indicate that the physical volume button is stuck.
Understanding the reason helps you choose the right strategy, if you just happen to be on the menu, a simple reset will help, and if a firmware failure precedes, more complex manipulations with ADB or firmware reflashing may be necessary.
The method of forced reboot with buttons
The first and safest way to try Xiaomi Redmi 4 Pro owners is the Hard Reset, which doesn’t delete your data, photos or contacts, it just forcibly breaks the power cycle and starts the bootloader again.
To implement this method, you don't need a computer or cables, all the actions are performed directly on the smartphone body, and the main thing is to observe the correct sequence and duration of the press, since the touch screen in Fastboot mode does not work.
Follow the following steps:
- Press and hold the power button on the side of the device.
- Don’t let go of the button, wait for about a minute. 10-15 The screen may go out, but keep holding it.
- Once the screen goes out, the device will begin to vibrate – this is a signal that the reboot process has begun.
- Release the Power button as soon as the Mi or Redmi logo appears.
💡
If the phone doesn't respond to a short press, try pressing the Power button for 20-30 seconds. Sometimes the power controller requires a longer signal to reset the static voltage.
In some cases, if conventional holding doesn't work, you can use a combination of buttons. Press the Power and Volume Up buttons for 10-15 seconds at the same time. This combination is often used to enter Recovery mode, but if the phone freezes, it can trigger a hardware reset.
If after these manipulations the phone shows the hare again, don't panic.The system may not be able to boot properly and require a battery check or deeper intervention.
Using the ADB command to exit
If the buttons don’t respond or the reboot cycle continues, the Android Debug Bridge (ADB) developer toolkit comes to the rescue, which requires connecting to a Windows, macOS or Linux computer and having drivers installed for Xiaomi.
The method is to send a software command that forcibly transfers the device from fastboot to normal boot mode (continue), a regular function of the bootloader that ignores software errors that block the start.
Instructions for using ADB:
- 💻 Download and install Minimal ADB and Fastboot on the computer.
- 🔌 Connect Redmi 4 Pro to PC via high-quality USB-cable.
- 📂 Open the command line (cmd) in the folder with the utility ADB.
- ⌨️ Enter the command to check the connection: fastboot devices.
If you see the serial number of the device, it's the link. Now enter the exit command:
fastboot continueAfter pressing Enter, the phone should restart immediately. If the fastboot continues command does not work, you can try an alternative reboot option via reboot:
fastboot reboot⚠️ Attention: Make sure that USB-cable is in good condition and is inserted into the port USB 2.0/3.0 directly to the motherboard, not through USB-An unstable connection may interrupt the transmission of the command, and the phone will remain in the menu of the hare.
This method is effective in 90% of software failures, and it forces the boot boot flag to change, telling the system to try to run the boot main partition again.
☑️ Pre-use checks ADB
Exit through the Mi Flash Tool
Xiaomi’s official Mi Flash Tool is primarily designed for flashing, but it can also be used as a diagnostic tool to help solve critical conditions, a method that is suitable if standard ADB commands fail or the bootloader is damaged.
You'll need to download the latest version of Mi Flash from the official website and drivers. Importantly, the utility often requires administrator privileges on the computer. Connect the phone in Fastboot mode to the PC.
Algorithm of action:
- Run the Mi Flash Tool on behalf of the administrator.
- Press the Refresh button in the program interface.
- If the device is identified, its serial number (device path) will appear in the list.
- In the lower menu, select the Clean all option (only if you’re willing to lose data) or just try Reboot if it’s available in your version.
What if Mi Flash can’t see your phone?
Sometimes, blind flashing of stock firmware helps. If you download a Fastboot ROM image for Redmi 4 Pro (unpack the archive), select it in Mi Flash and press Flash, the program will try to restore boot sectors. This is a last resort, but it is guaranteed to take the phone out of the "brick" or eternal Fastboot state.
Remember that using Mi Flash with Clean all option will completely remove all data from internal memory. Use Save user data option (if available for your firmware version) to save files, although this is rarely required when you exit Fastboot, as we do not change the software version.
Diagnostics of hardware problems and batteries
If software methods fail, the problem may be hardware. Xiaomi Redmi 4 Pro — the device is not new, and the wear of components plays a role. Often the cause of cyclic input to the Fastboot is a critically low battery charge.
When the battery voltage drops below a certain threshold, the power controller cannot ensure a stable start of the processor. as a result, the phone either turns off or goes into emergency mode. In Fastboot mode, energy consumption is higher than in the off state, so the phone can quickly discharge even when connected to a weak charger.
Table of possible symptoms and solutions:
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The screen flashes, the phone vibrates. | Volume button sticking | Carefully tap the button, remove the cover |
| The phone is warming up in Fastboot mode | CZ in the power supply chain or controller | Urgently disconnect from the network, carry to the service |
| Not charged, the indicator is on. | Deep battery discharge | Leave on charging for 2-3 hours without inclusions |
| Cyclical Reboot (Bootloop) | System partition error | Complete reset (Wipe Data) or flashing |
If the Micro-USB port has accumulated dust or oxidation, the contact may be unstable, try to clean the connector gently with a non-metallic toothpick and wipe with alcohol.
💡
If the phone is heated in Fastboot mode and doesn't leave it for more than 30 minutes, turn it off immediately. Prolonged overheating can swell the battery or damage the motherboard.
Prevention and preservation of data
After successfully exiting Fastboot mode and booting into the system, it is recommended to carry out preventive measures. Redmi 4 Pro has a tendency to software failures when memory overflows or application conflict.
First of all, free up space on the internal drive. Lack of space for system files is a common cause of bootloader failures. Delete the messenger cache, old photos and unnecessary applications. Also check for MIUI updates in the settings.
For data protection in the future:
- ☁️ Set up automatic sync with Mi Cloud or Google Drive.
- 🔄 Make regular backups through the built-in Security app".
- 🛡️ Do not install applications from unknown sources, they can damage system files.
If the login problem is repeated regularly for no apparent reason, consider completely flashing the device with all data cleared, which will return the phone to factory status and remove possible software errors accumulated during operation.
⚠️ Warning: Don't try to disassemble the Redmi 4 Pro body yourself if you don't have experience.Adhesive frame and fragile screen plumes can be damaged, leading to costly repairs.If you suspect a hardware fault, you should contact the service.
