Why Xiaomi has a Fastboot image and how to fix it

You turned on your Xiaomi smartphone, and instead of your desktop, you had a black screen with a green robot and the word Fastboot? It's not a malfunction, it's a special engineering mode that can be activated either by mistake or by serious system failures, and in 80 percent of cases, you can solve the problem yourself without going to the service center.

Fastboot (or fastboot in newer versions of MIUI) is a low-level tool for firmware and diagnostics for Android devices that runs before the operating system loads, allowing you to restore the smartphone even when critical errors. However, for the average user, getting into this mode often comes as a surprise. In this article, we will analyze all the possible reasons for the appearance of the Fastboot screen on Xiaomi (including Redmi, POCO and Black Shark), and give step-by-step instructions for exiting it, from the simplest to advanced methods.

Why Xiaomi is loading into Fastboot: 7 main reasons

The screen with the green robot and the FASTBOOT sign on it at the bottom doesn't just appear, but here are the most common scenarios that lead to this situation:

• 🔄 Incorrect update MIUI. Interrupted firmware through OTA or manually installing an incompatible version of the software.
• 🔋 If the charge dropped below 5% during critical operations (update, reset), the system may lock down.
• 🔧 Failure after unlocking the bootloader. Wrong fastboot commands or interrupted unlock process.
• 📱 Hardware problems: Power button damage, device fall or moisture.
• 🛠️ Failed factory reset, especially if it was done through Recovery with errors.
• 🔌 Problems with cable or charging. Using non-original accessories during firmware.
• 🤖 Conflict with custom firmware. Installation of informal ROM (LineageOS or Pixel Experience without proper preparation.

It's important to understand that Fastboot is not a bug, it's a tool. The system goes into this mode when it can't boot properly. For example, if the boot partition is damaged or critical system files are missing. On Xiaomi devices with Qualcomm processors (most Redmi and POCO models) it's often enough to reboot to exit the Fastboot, but on smartphones with Mediatek chips (for example, Redmi Note 11 or POCO M4 Pro) it may require manual intervention.

Method 1: Forced reset (works in 60% of cases)

The easiest method to try is suitable for all Xiaomi models, as long as the reason for getting into the Fastboot is not related to hardware damage.

☑️ How to reboot Xiaomi from Fastboot: 0 / 1

On some models (e.g. Redmi Note 10 Pro or POCO X3 Pro), the button combination may differ:

If the Fastboot screen reappears after the reboot, it means that the problem is deeper, whether the boot partition is damaged or critical system files are missing, in which case proceed to the following methods.

⚠️ Note: Do not try to “pull out” the battery on non-removable models (for example, Xiaomi). 12T or Redmi K50). This will result in loss of warranty and may damage the plumes.

Method 2: Boot in Recovery Mode and Reset Settings

If forced reboot doesn't work, the next step is to try booting into Recovery Mode and resetting to factory settings, which will delete all the data from the device, but return it to working condition.

Instructions for most Xiaomi models:

1. Turn off the device (if it is in Fastboot, press the power button for 15 seconds).
2. Press the combination: Power + Volume up - for most Redmi/POCO. Power + Volume down - for Mi 10/11/12.

Hold the buttons until the Mi logo and Recovery menu appear.

Use volume buttons for navigation and power button for selection.

Select Wipe Data → Wipe All Data (full reset).

After reset, select Reboot → Reboot to System.

On new devices (such as Xiaomi 13 or Redmi Note 12), the Recovery menu can be in Chinese.

• 🧹 — dataset ().
• 🔄 — restart ().

After resetting, the device should boot in normal mode. If this does not happen, move on to more advanced methods.

Method 3: Firmware via Mi Flash Tool (for power users)

If the reset didn’t work, the firmware was likely damaged, in which case you’ll need to reflash the device through the Mi Flash Tool, Xiaomi’s official Fastboot tool.

You'll need:

• 🖥️ Windows computer (7/10/11).
• 🔌 Original. USB-cable (preferably from the set).
• 📥 Firmware for your model (download from the official Xiaomi website).
• 🛠️ The Mi Flash Tool.

Step-by-step:

1. Download and install the Mi Flash Tool.
2. Unpack the archive with firmware (should be a file with the.tgz or.zip extension).
3. Connect the device turned off in Fastboot mode to the PC (clip Volume down + Power when connecting the cable).
4. In the Mi Flash Tool, click Select and specify the path to the unpacked firmware.
5. Press Refresh – the program must determine the device (appears) COM-port).
6. Select firmware mode: Clean All - complete cleanup (recommended for critical failures); Clean All and Lock - cleanup + lock the bootloader (if unlocked); Save User Data - data storage (not always stable).

Press Flash and wait for the process to end (5-10 minutes).

Once the firmware is up, the device will automatically restart. The first run can take up to 15 minutes -- that's normal.

⚠️ Note: Firmware via the Mi Flash Tool deletes all data, including photos and apps. If your device had important files, try using the method first. ADB Sideload (described below).

💡If the Mi Flash Tool doesn’t see the device, try it:

Method 4: Recovery via ADB Sideload (without data loss)

If you don't want to lose data, you can try to restore the system through ADB Sideload, which is suitable if the device can boot into Recovery, but does not start normally.

What you need:

• 🖥️ Computer with installed ADB and Fastboot.
• 📥 Firmware for your model in.zip format (download from Xiaomi Firmware Updater).
• 🔌 USB-data-couple.

Instructions:

1. Download the device to Recovery Mode (as described in Method 2).
2. Select Connect with MiAssistant (or ADB Sideload on newer versions).
3. Connect your smartphone to your PC.
4. Open the command line in the folder with platform-tools and type: adb devices The device should appear in the list.
5. Enter the command for firmware: adb sideload name file.zip (replace the name file.zip with the real name of the firmware).
6. Wait for the process to end (the device will have a progress bar on the screen).
7. Once completed, select Reboot system now.

This method saves user data, but may not work if critical system partitions are damaged. If Fastboot reappears after the reboot, you will have to use the Mi Flash Tool with a full cleanup.

Method 5: Checking for hardware problems

If none of the software methods worked, the problem could be hardware.

• 🔋 Battery: If the charge is below 5%, the device will not be able to boot properly.
• 🔌 USB-port and cable. A damaged cable or port can cause charging/firmware failures. Try another cable and port.
• 🔨 Power button: If the button is stuck or damaged, the device can be rebooted continuously.
• 💧 If the smartphone fell into the water, it could oxidize the contacts, and then only disassembly and cleaning will help.
• 🔧 Falls and bumps: Damage to the motherboard or chip dumps can make it impossible to load.

To diagnose hardware problems, you can use the Xiaomi test menu (if the device somehow responds to the buttons):

1. Press Volume up + Volume down + Power for 10 seconds.
2. If you see a test menu (such as Version, Item Test), select Test All Items.
3. Check the reaction to pressing, display operation, vibration and charging.

⚠️ Note: If the test menu shows errors of the type EMMC error DRAM Fail, this indicates memory damage. You can't fix it yourself, you need to replace the chip at the service center.

When to contact the service center

If you’ve tried all the methods, but Fastboot still appears every time you download, it’s probably more serious than it seems.

• 🔧 After firmware is run through the Mi Flash Tool, the device does not turn on at all (black screen, no reaction to buttons).
• 🔥 Artifacts, stripes or flickering appear on the screen - this is a sign of a problem with the display or graphics chip.
• 🔌 The device is not detected by the computer even in Fastboot mode (no connection sound, no display in Device Manager).
• 💾 The test menu shows errors EMMC, UFS or DRAM.
• 🔋 The battery does not charge (even after replacing the cable and power supply).

The cost of repairs in official Xiaomi services depends on the problem:

Before visiting the service, do the following:

• Take a picture of the screen with an error (if it changes).
• Write down the device model and firmware version (if known).
• Check if the warranty is maintained (if so, repairs can be free).

💡If the device is warranty, DO NOT try to sew it yourself.Any interference with the firmware will void the Xiaomi warranty.
