Fastboot on Xiaomi: what is this mode, why it is needed and how to turn it off forever

Have you ever seen a Fastboot Mode with a rabbit in a hat on your Xiaomi screen? This mode often becomes a headache for users, especially if the smartphone has been getting stuck in it after a failed update or experiments with firmware. In this article, we will understand what a Fastboot on Xiaomi, why it appears and, most importantly, how to turn it off without the risk of turning the phone into a brick.

Fastboot is not just a boot mode, it's a powerful tool for low-level device management. It lets you install custom firmware, unlock the bootloader, or restore the system after a crash. However, for the average user, getting into this mode is often a surprise. For example, if you accidentally pinch a button combination when you turn on or interrupt the MIUI update. Unlike Recovery Mode, where you can still do something through the menu, Fastboot requires a connection to a PC or special commands.

It’s important to understand that disabling Fastboot on Xiaomi doesn’t mean physically removing it — it’s impossible without changing the firmware at the kernel level. It’s about leaving the mode or turning off autoboot when you turn on your smartphone. Next, we’ll look at all the working methods, including “soft” (without data loss) and “hard” (with a full reset).

What is Fastboot on Xiaomi and why is it needed?

Fastboot mode (or fastbootd in newer versions of Android) is a diagnostic protocol that allows you to interact with the device loader via USB- connection to the computer. It is built into absolutely all Xiaomi smartphones, from budget Redmi to flagship Mi and POCO, and serves to:

• 🔧 Install official and custom firmware (MIUI, LineageOS, Pixel Experience).
• 🔓 Unlock the bootloader to obtain root rights.
• 🛠️ System recovery after “bricking” (for example, if the smartphone is not turned on due to a damaged boot partition).
• 📥 Firmware of individual partitions (e.g., recovery, modem, or vendor).
• 🔄 Resetting a password or pattern lock (in some cases).

The difference between Fastboot and Recovery Mode is that the first one is at the bootloader level, and the second one is at the system recovery level. For example, in Recovery you can reset to the factory settings (Wipe Data), and in Fastboot you can reflash the bootloader or the kernel itself.

On the screen of the smartphone Xiaomi in Fastboot mode you will see:

• 🐰 Logo with a rabbit in a hat (symbol of Mi Bunny).
• 📱 Inscription FASTBOOT or Fastboot Mode.
• 🔌 Connection indicator according to USB (if the cable is connected to a PC).
• 🔄 Loader status lines (Device is LOCKED or UNLOCKED).

If your Xiaomi is loading into Fastboot on its own (without your involvement), this is a sign of one of the problems:

⚠️ Warning: Auto booting in Fastboot may indicate a boot partition damage, firmware conflict, or Fastboot Auto Reboot activated option in the engineering menu. Don't try to "get out" by repeatedly pressing buttons - this can exacerbate the problem.

Reasons to Get into Fastboot on Xiaomi: Why the Phone Boots in This Mode

Xiaomi smartphone can be loaded into Fastboot for several reasons.

One of the most insidious reasons is the activated Fastboot Auto Reboot option, which can be activated after experimenting with an engineering menu or installing unofficial firmware, in which case the phone will boot to the Fastboot even after a normal shutdown.

Another common situation is that the user tries to get root rights, unlocks the bootloader through the Mi Unlock Tool, but forgets to return everything back, as a result, the smartphone either constantly loads into the Fastboot or refuses to turn on at all.

How to exit Fastboot on Xiaomi without losing data (soft way)

If your Xiaomi booted into Fastboot by accident (for example, because of button pressing), you can exit this mode without losing data.

1. Hold the Power button for 10 to 15 seconds until the screen goes out. This will force the phone to turn off.
2. Wait 5-10 seconds, then press the Power button once to turn on the smartphone in normal mode.
3. If the phone loads again in Fastboot, try the combination: Volume up + Power Hold it until the Recovery Mode menu appears.
4. In Recovery, select Reboot → Reboot to System (use volume buttons for navigation and power for confirmation).

If these methods don’t work, try connecting your phone to charge for 10 to 15 minutes, and then repeat the steps. Sometimes the problem is a dead battery, which can’t boot properly.

💡

If you've left Fastboot, you've got your phone stuck on the MI logo, wait 5-10 minutes, maybe you're optimizing your apps after you crash. Don't force it to shut down!

If the soft method did not help, you will have to move to more radical measures – reset via Recovery or firmware through Fastboot.

How to disable autoboot in Fastboot on Xiaomi (if the phone itself gets there)

If your Xiaomi is constantly loading into Fastboot after every shutdown, the problem is most likely in the activated Fastboot Auto Reboot option.

Method 1: Engineering menu (if the phone is switched on)

1. Open the phone app and enter the combination: ##4636##
2. In the menu that appears, select Testing → Fastboot Auto Reboot.
3. Turn off the option (should be Disabled).
4. Reboot the phone.

Method 2: Through ADB- commands (if the phone is not switched on normally)

If your smartphone is stuck in Fastboot but is determined by your computer, follow the following steps:

1. Install ADB and Fastboot Tools on PC.
2. Connect your phone to your computer via USB (USB Debugging Mode should be enabled, but if the phone doesn’t turn on, skip this step).
3. Open the command prompt (CMD) in the folder with the platform-tools and type: fastboot oem disable-fastboot-auto-reboot
4. If the command is not working, try: fastboot oem config bootmode normal
5. Reboot your phone with the command: fastboot reboot

If these commands are not supported by your Xiaomi model, try resetting the bootloader settings to factory:

fastboot oem edl

After that, the phone should restart in normal mode.

How to completely remove Fastboot from Xiaomi: myths and reality

Many users are looking for a way to completely remove Fastboot from their Xiaomi, considering it a “virus” or an unnecessary feature.

• 🔒 Fastboot is a piece of bootloader that is sewn into the hardware of a smartphone, and can only be physically removed by soldering the memory chip (which is equivalent to killing the phone).
• 📱 Even custom firmware (like LineageOS) use Fastboot to install.
• 🔧 Without Fastboot, you won’t be able to update your firmware, unlock your bootloader, or restore your phone after a crash.

What you can do:

• 🔕 Disable autoboot in Fastboot (as described above).
• 🔄 Lock the bootloader so you don't accidentally get into firmware mode.
• 📵 Disable debugging by USB in the developer settings (Settings → About Phone → Version MIUI – tap 7 times, then go back to Additional Settings → For Developers).

⚠️ Warning: Some craftsmen advise reflashing a phone with the Fastboot disabled via the SP Flash Tool or QFil. This is extremely dangerous! Without the right bootloader, the smartphone will turn into a brick, and only be able to restore it in the service center using EDL- mode (which is a paid service).

If you’re annoyed by the fact that Fastboot exists, the only safe way to do so is to use your smartphone “as is” without interfering with system settings. Modern versions of MIUI (starting with MIUI 12) minimize the risk of accidentally getting into this mode.

What to do if Xiaomi is stuck in Fastboot and doesn’t get out: radical methods

If the softer ways didn't work, and the phone loads hard into the Fastboot, you'll have to use more serious measures.

Method 1: Recovery (without data loss but with cache cleaning)

1. Turn off the phone (hold power for 10-15 seconds).
2. Hold on to the combination: Volume up + Power until the Recovery menu appears (the Mi logo with android robot).
3. Select from the menu: Wipe & Reset → Wipe Cache
4. After cleaning the cache, go to Reboot → Reboot to System.

Method 2: Hard Reset (Hard Reset) through Recovery

If cleaning the cache didn't help, do a full reset.Warning: it will delete all the data on the phone (photos, contacts, messages)!

1. From the Recovery menu, select Wipe & Reset → Wipe All Data.
2. Confirm the action (usually you need to enter Yes or press the power button).
3. After reset, select Reboot to System.

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

If the smartphone does not boot into the system at all, you just need to flash it through the Mi Flash Tool:

1. Download the official firmware for your model from en.miui.com (select the Fastboot version).
2. Install the Mi Flash Tool on your PC.
3. Connect your phone in Fastboot mode to your computer.
4. In the Mi Flash Tool, select the downloaded firmware and press Refresh (your Xiaomi should be determined).
5. Press Flash and wait for the process to end (10-15 minutes).

Once the firmware is installed, the phone should boot as normal, and if that doesn’t work, you just have to carry the device to the service center — possibly a hardware problem (damaged memory or controller).

💡

Firmware via the Mi Flash Tool is the most reliable way to bring your phone back to life, but it requires official firmware for your model. Don't use firmware from other devices!

Frequent Mistakes When Working with Fastboot on Xiaomi and How to Avoid Them

Fastboot is fraught with errors that can turn your Xiaomi into a brick, and here are the most common ones and how to prevent them:

One of the most dangerous mistakes is to interrupt the firmware through the Mi Flash Tool. If the process was interrupted (for example, due to a USB shutdown or battery discharge), the phone may stop turning on at all, in which case only firmware in EDL- mode will help (and this requires an authorized Xiaomi account or contacting the service).

Another common problem is the conflicting versions of MIUI, for example, if you try to put Global ROM on a phone with China ROM without unlocking the bootloader, you get an anti-rollback error, in which case you have to go back to the old version of the firmware or unlock the bootloader officially.
