Xiaomi Redmi 4 is one of the most popular budget smartphones of the brand, but even it is not immune to loading problems. Fastboot mode (or fastboot) is an engineering mode that is used to firmware, unlock the bootloader or restore the system. However, many users face a situation when the device βhangsβ in this mode and can not boot properly. Why this happens and how to safely exit the Fastboot on Redmi 4 (including versions of Redmi 4 Pro, Redmi 4A and Redmi 4X) β we will discuss in this guide.
It's important to understand that the reasons for getting into a fastboot can be different, from accidentally pressing buttons to a firmware failure or an unsuccessful attempt to unlock the bootloader. Some exit methods require a connection to a PC, others work directly on the phone. We'll look at all the current ways, including those that will help if the smartphone does not respond to standard commands.
What is Fastboot Mode and Why is Redmi 4 Stuck in It?
Fastboot Mode is a low-level tool for interacting with Xiaomi bootloader that allows you to:
- π§ Install custom firmware (custom) ROM)
- π Unlock the bootloader (bootloader)
- π± Restore the system after failures
- π Switching separate sections (e.g. recovery or boot)
However, sometimes Redmi 4 spontaneously goes to Fastboot or βhangsβ in it after:
- β‘ Failed update MIUI via Updater
- π Interrupted firmware through the Mi Flash Tool
- π οΈ Pattempts unlock the bootloader without official permission
- π Critical discharge of the battery during operation with the system
If your Redmi 4 screen has a bunny on it with a FASTBOOT tag on it and the device doesn't respond to the power button, that's a sure sign of a problem, and in most cases, it can be solved without going to the service center, but it's important to act carefully to avoid making things worse.
Method 1: Standard button exit (without PC)
If your smartphone responds to physical buttons, try the easiest way to do this:
- Press the power button for 10-15 seconds until the screen goes out.
- After vibration, release the button and wait for the normal load.
If the device returns to Fastboot again, try the combination:
- π Power button + volume up (hold 10-20 seconds)
- π Power button + volume down (similar to volume down)
On some versions of Redmi 4 (especially custom firmware) the triple combination of power + both volume buttons can work, holding it until the MI logo or vibration appears.

If the smartphone is under 5%, it may not respond to the buttons. Connect it to charge for 10-15 minutes, then try again.
Method 2: ADB and Fastboot commands (PC required)
If the hardware buttons donβt help, connect Redmi 4 to your computer and use ADB and Fastboot utilities.
- Download and install Platform Tools (includes adb and fastboot).
- Connect your phone to your PC through USB-cable (preferably original).
- Open the command line (Win + R β enter cmd) and go to the folder with utilities: cd C:\platform-tools
- Check if the device is detected: fastboot devices If the answer is blank β install Xiaomi drivers or try another one USB-port.
Now run the command to reboot:
fastboot rebootIf this does not work, try to force the system to boot:
fastboot continueβοΈ Preparation for work with Fastboot
Method 3: Recovery via Mi Flash Tool (if the firmware is damaged)
If Redmi 4 is stuck in the Fastboot because of a firmware failure, you may need to reinstall it.
- Download the official firmware for your model from MIUI Downloads (choose the Fastboot version, not Recovery).
- Unpack the archive in a folder without Cyrillic characters (for example, C:\Redmi4_Firmware).
- Download and install the Mi Flash Tool.
- Connect your phone in Fastboot mode to your PC and launch the Mi Flash Tool.
- Click Select, specify the path to the firmware folder, then select Clean all (full clean) or Clean all and lock (if you want to lock the bootloader).
- Press Flash and wait until it is completed (the process will take 5-10 minutes).
Warning: Clean all and lock will lock the bootloader, which will require re-unblocking through Xiaomi's official permission.If you're unsure of your actions, choose Clean all.
| Firmware variant | Description | Effects of consequences |
|---|---|---|
| Clean all | Deletes all data, flashes clean MIUI | The loader remains unlocked |
| Clean all and lock | Deletes data + blocks the loader | Re-unblocking required |
| Save user data | Switches without deleting user data | It may not work in case of serious failures. |
What to do if the Mi Flash Tool is in error?
Method 4: Unlock the bootloader (if the reason is blocking)
If Redmi 4 is stuck in Fastboot after trying to unlock the bootloader, it may have been interrupted or not completed.
- Make sure you have official permission to unlock (you can get it from Mi Unlock).
- Download and install the Mi Unlock Tool.
- Connect your phone in Fastboot mode to your PC.
- Launch the Mi Unlock Tool, log in to your Mi Account (the same one used to get permission).
- Press Unlock and wait until it is completed (usually takes 1-3 minutes).
Once successfully unlocked, the phone should automatically restart. If this does not happen, type in the command line:
fastboot rebootβ οΈ Warning: Unlocking the bootloader resets all data on the device! Pre-backup important files if the phone still turns on.
Method 5: Hardware reset via Test Point (extreme case)
If none of the methods worked, and the phone doesnβt even respond to Fastboot commands, a hardware reset via Test Point may be required, a method that works for a Redmi 4 with a dead bootloader, but requires disassembling the device.
Instructions:
- Turn off the phone (if it does not turn off, wait for the full discharge).
- Remove the back cover and disconnect the battery for 30 seconds.
- Find Test Point (two metal dots next to the battery connector, usually signed TP).
- Close them with tweezers or screwdrivers, simultaneously connecting USB-plug-in.
- If the drivers are installed, Qualcomm HS-USB QDLoader 9008 will appear in Device Manager.
- Use the Mi Flash Tool to run in EDL (Emergency Download) mode.
Important: Test Point failure can damage the motherboard. If you're unsure of your skills, contact the service center.

Test Point is the last chance to repair the brick, and only use it if other methods have failed and you are prepared to risk damage to the device.
Frequent Mistakes and How to Avoid Them
Many users compound the problem by trying to exit Fastboot in the wrong ways.
- π Using unoriginal cables is cheap USB-cables may not transmit data in Fastboot mode, which is why commands do not pass through.
- π Battery discharge β if the charge is below 20%, the phone may shut down during the operation, leading to an even more serious failure.
- π₯ The firmware is the wrong version MIUI β firmware installation for Redmi 4A Redmi 4 Pro (or vice versa) will make the device inoperable.
- π Ignoring bootloader Unlocking β Trying to flash custom recovery without official unlocking will lead to an anti-rollback error.
To minimize the risks:
- β Always check the phone model in Settings β About the phone (for example, Redmi 4 Pro has the code name markw, and Redmi is codenamed "Traffic" 4A β rolex).
- β Use only official firmware from the Xiaomi website.
- β Before any manipulations with the system charge the phone up to 50% or more.
