If you are a happy owner of a gadget on the Android platform, then sooner or later you will come across such an interesting phenomenon as Fastboot Mode. What it is? Why is it needed? These questions arise in a person's head much later.
The first thought at the sight of Fastboot is completely different. Oh my god, I broke my device! In order to avoid panic, you need to figure out what kind of regime it is, why it is needed and how to get out of it. The main thing is not to panic and strictly follow these instructions. If you panic and fail to perform all the steps correctly, you can end up with a dead smartphone as a result. Do you need it?
What is this mode?
Essentially, Fastboot mode is fast access to the interior of the device. It just boots past the slow BIOS and does it very quickly. Usually, Fastboot mode cannot be entered without pressing certain keys. But it also happens that due to some kind of "glitch" the device itself goes into this mode. And here you need to know the procedure in order to get him out of this hibernation. There is nothing complicated about this, but many unprepared users are terribly afraid of Fastboot Mode. What to do? How to return everything to its place? The reason for the panic is understandable, but you need to calm down and follow the instructions clearly. Then everything will be fine with your gadget.
What is it for?
There are several reasons for implementing Fastboot mode in the device. Firstly, it helps the device to boot faster, because this way the download occurs bypassing the slow BIOS. Secondly, Fastboot helps developers communicate with the device at the hardware level, and this is very important. Thirdly, Fastboot allows you to customize operating system"Android" using a computer via an ADB connection. That's what Fastboot Mode is for. What it is is now clear. Now let's move on to the question of what to do if your gadget unexpectedly boots into this mode.
How to get out of this mode?
If the Fastboot mode was turned on by mistake, then this is not so bad. It is enough to hold down the power button and the "Volume up" button on the turned off device. The device will boot into BIOS. Here you need to select the item "Reboot system now" (Reboot system now). After that, the "correct" loading of the device should begin, bypassing Fastboot Mode. What it is, we have already sorted out a little higher. If the BIOS does not have the above item, then things are very bad. You will have to follow the steps to return the device to factory settings.
If the device itself decided to boot into Fastboot mode, then something is wrong with its settings. You will have to wipe the user data in order not to get into Fastboot Mode again. What it is? On "Android" devices, a system for rolling back to the factory settings is provided for just such cases. It "resets" the device to factory specifications. In this case, all user data (applications, contacts, music) is deleted.
You need to go into BIOS mode and select "Wipe Data" (Wipe Data) and "Reset to factory settings" ( factory reset). After that, we reboot the smartphone from the item "Reboot system now" (Reboot System Now).
How to remove the mode?
In fact, ordinary user no need for fastboot mode. How to get out of it, we already know. Now consider the question of how to disable it permanently. It is enabled by default and sometimes just confuses the user. To prevent this from happening in the future, we turn off this mode. To do this, go to the smartphone settings, the menu item "Screen", and find the inscription "Quick download" there. You just need to uncheck the box.
This algorithm of actions is relevant for the Android operating system version 4.0 and higher. If you have an older version of Android, then you need to look for the item you are looking for somewhere in the "Applications" section. These steps will help turn off Fastboot mode completely. And he won't bother you anymore.
However, now many will be dissatisfied. Do not completely get rid of Fastboot Mode. What it is? On Android smartphones, it also performs the function of "recovery". And this is very important.
Why not get rid of it entirely?
Regrettably, but Fastboot is an important component software device. And turning it off completely is a very bad idea. The fact is that if this function is disabled, then you will not be able to install firmware on it through a computer if your device suddenly turns into a "brick". And this happens all the time. So in this case, only Fastboot Mode can save you.
What is it we, sorted out a little higher. Let's just say, this is your "lifeline" in case of unforeseen situations that may happen to your smartphone. So don't turn it off. There will come a time when you'll be glad you refrained from completely disabling Fastboot mode. It does not bother the user at all. You just need to know how to get out of it.
Summary
So, summing up all of the above, we can say for sure that the Fastboot mode is a very useful thing.
- Firstly, it allows the gadget to boot faster bypassing the BIOS.
- Secondly, it makes it easier for developers to communicate with the device.
- Thirdly, it can be used to upload patched firmware using a computer and an ADB connection.
- Fourthly, it helps a lot if your smartphone suddenly turned into a "brick".
And against all these advantages, one tiny drawback - you did not know how to get out of it. But now you know, so you don't need to disable Fastboot. You will still need it.
Fastboot Mode is a special mode used on Android phones and is needed for debugging a mobile, flashing it, and other interference with system files. It is also applied for fast loading. In addition to Android, Fastboot is also found on other devices, but in this article we will focus on smartphones from Google. We will tell you why the mode can turn on, what it is, why it is needed and what to do to get out of it. Let's get started.
What is Fastboot Mode on Android
Initially, let's figure out what Fastboot Mode is, and we are interested in the operating system platform from Google.
Fastboot Mode is a debugging protocol that is part of the Android SDK (Android software development), which means Android software development. This mode is used to debug the operating system itself (firmware), to update it or install additional components.
The peculiarity of this method of loading Android is that the OS itself does not start, the device only initializes the driver needed to be able to read or write to the phone's FS. You need to work with Fastboot Mode most often through ADB command line, but sometimes special software is used for this.
Here are the most common commands that are used when working with Fastboot Mode:
- Flash is a firmware mode that overwrites the device's memory, in which the Android operating system is stored.
- Erase - erasing a section or the entire file system as a whole. Required for a "clean" installation of the OS.
- Reboot - a command to exit Fastboot and return the phone to the main operating system (in our case, Android).
- Format - used to format a section, sections, or general formatting.
In order for a device switched to Fastboot Mode to be recognized by a computer or laptop, you need to install special drivers on Windows that are released separately for a particular phone model.
What is it for
Now you know what it is, it remains only to explain where and why this mode is used. Access technology in Fast Boot is used in such cases:
- Firmware for android phones.
- Operating system update from Google.
- Elimination of errors caused by failures in the OS.
- Editing system files(meaning the firmware).
- Bypass Android FRP using, for example, Fastboot Android Reset Tool.
- Reading hidden information about the device, which cannot be obtained without interfering with the internal FS.
Attention: change an identification number Android-based phone (IMEI) cannot be used via Fastboot. Since this parameter is wired into a separate microcircuit, access to which cannot be obtained by conventional means.
Why does it appear
Sometimes the user is faced with the fact that Fastboot mode is activated on his phone, although, according to the person, this should not happen.
Fastboot Mode on Android can be activated for the following reasons:
- The user accidentally pressed a combination of buttons assigned to activate the "fast download" mode on his gadget.
- A firmware failure has occurred, as a result of which the operating system can no longer boot normally.
- From the computer, with USB debugging enabled, a signal was received to start the mode.
If you see a black screen with a debug image, do not be afraid. It is usually very easy to exit Fastboot and boot into Android. We'll show you how to do it below.
How to exit Fastboot
There are several ways to disable the "fast boot" mode at once. Consider each of them in more detail, for clarity, we will use step by step instructions, each step of which is accompanied by a screenshot. Let's start with more simple options and only if they do not help, move on to the next method.
Reboot
The easiest way is to restart your phone. To do this, hold down the power button and hold it until the device resets. In this case, a characteristic vibration signal will follow, after which the power key must be released.
If, after rebooting, the gadget again writes about enabling the “fast boot” mode, proceed to the next method of deactivating it. If your device has a removable battery, try taking it out, waiting a couple of minutes, and then putting it back in.
Important: the inclusion of the Recovery mode on Android is performed exclusively from the off state.
Return to factory settings
You can also try turning on the Recovery mode, which is found in any Android phone.
Options for enabling Recovery on different devices:
If your device is not in the table, you can find necessary information online or ask a question in our Telegram group.
Through the reboot menu
So, when we get into recovery mode, we need to do the following:
The example below is based on a phone Xiaomi Redmi Note 4x, but everything will look about the same in other models.
- Let's go to Recovery.
- Using the volume up and down buttons, select the reboot point to the system. The choice is most often made by the power button.
- We are waiting for a reboot.
If it doesn't help, go to the next section.
Formatting internal memory
You can also try disabling Fastboot on Android by formatting it internal memory. Below we describe how this is done.
Attention! This method involves deleting all user data, including photos, videos, music, etc.
- We start the Recovery mode again and select the item Wipe All Data. We apply our choice and confirm it.
- We confirm our intention.
- We are waiting for the formatting of the internal memory to finish, then we are waiting for a reboot into the main operating system. Keep in mind that the first start after a factory reset may take some time. Sometimes it is even 10 or more minutes. At the same time, the smartphone seems to “freeze” at the power-on logo. Here you just have to wait.
Fastboot started again? Then read on.
By PC
This instruction will help out those who have not been helped previous options. But it is she who has the greatest efficiency. Let's get started.
Attention: the instruction you will find below is shown on Xiaomi example Redmi Note 4x and is for reference only. If you have a different model, check the procedure for information from thematic forums.
- We open Yandex or Google and write a request by our phone. We find the w3bsit3-dns.com forum and go to it.
- In order to download files here, you must register. The procedure will take only 2-3 minutes.
- Initially, download the driver for Android Fastboot Mode.
- Then we download ADB itself.
- Unpack the driver into one of the folders that you need to create first.
- We start the installation depending on the bitness of the operating system.
In order to check which Windows you have, use the hot key combination Win + Pause / Break. In the line marked in the screenshot, you will see the architecture of your Windows.
- We continue installing ADB to exit Fastboot. Here just click on Next.
- In an instant, the installation will be completed. Click the button below.
Let's move on to installing ADB.
- Unpack the downloaded files to any created folder.
- Run the file marked in the screenshot.
- Enter "Fastboot reboot" into the command line. Then press Enter.
Attention: At this point, Android must be connected to the PC via USB.
As a result, a reboot will follow and your smartphone will start in normal mode.
If this option did not suit you either and Fastboot on Android is still active, all that remains is to reflash the phone.
Firmware
Flashing is the last but most effective method to get your Android out of Fastboot. Before we continue, a reminder:
The instruction is given on an example Xiaomi smartphone Redmi Note 4x / 5x, for other gadgets, other options and firmware are used. By installing the wrong software, you run the risk of "killing" your phone.
So, let's see how the firmware of our Chinese device is made.
- The first thing you need to do is download the firmware for your Android. It is best to do this on the popular w3bsit3-dns.com forum. We register the request in the search bar and select our forum.
Fasboot (fastboot)- this is a special mode that allows you to conduct low-level with the device under Android control various actions - flashing, unlocking the bootloader, installing custom recovery, etc. But if something went wrong during the service operations, the phone may freeze in this mode without the possibility of a normal boot.
How to determine if the phone is in fastboot mode

In our instructions for flashing and unlocking the bootloader, “fastboot mode” is often mentioned (translated into Russian as “fastboot mode”). What is fastboot, where to download and how to use, we will tell in this material.
What is fastboot mode
This is embedded in Android device Software that allows you to control via PC. For control, text commands are used that are entered into the console - the command line.
It's important to note that fastboot is three things with the same name but different purposes:
- Protocol in the form of a bootloader control system from a computer.
- Software that runs on a device in fastboot mode.
- Executable on the computer, which is used to communicate between the mobile device and the computer.
Usually, when you see an action in the instructions: “boot smartphone to fastboot”, “reboot to fastboot” or “go to fastboot”, it means to start this mode on mobile device for further interaction with the computer.
Almost all smartphones and tablets support the fastboot control protocol. Exception - some manufacturers mobile platforms, for example, where a different bootloader is used that is incompatible with fastboot. Therefore, other "tools" are used to manage and flash devices where fastboot is not supported.
How to get out of fastboot mode
There are three ways to exit fastboot mode:
- By entering the fastboot reboot command.
- Hold down the power button for 15-20 seconds.
- Removing the battery.
If the device is in fastboot mode, and you are finished and want to boot the operating system, then enter the fastboot reboot command. The machine will reboot and the system will boot by default. The method will not work if the cable is damaged. For example, there was a break in the wire responsible for data exchange.
Exiting fastboot mode also helps by holding the power button for a long time, usually up to 20 seconds. The method is effective if the command to reboot the device did not work. It does not work if the button is damaged.
Barbaric, but in some cases effective method- remove the battery, if such a possibility is provided for by the design. After returning the battery back, the phone will boot the OS by pressing the power button.
The purpose and capabilities of fastboot
The fastboot protocol is designed to restore the device, in case of deletion or incorrect firmware, of one or all partitions, including recovery. Therefore, fastboot comes in handy when other methods fail.
List of some operations performed via fastboot:
- Transfer to fastboot mode.
- Check condition and factory .
- , kernel, or another partition.
- Delete or format a specific partition.
Conclusion
What is fastboot mode (fast boot mode) and how to exit fastboot mode is described in detail in the article. The fastboot protocol is an important mechanism for working with the device and restoring the system, after unsuccessful firmware, since fastboot is not going anywhere even if all partitions are deleted. At the same time, any system recovery process is easier if the bootloader is in an unlocked state.
