What does select boot mode. What is Fastboot on Xiaomi phones and how to exit the mode

Fastboot Mode is a special mode used on Android phones and necessary for debugging a mobile, its firmware and other interference with system files. It is also used for fast loading. In addition to Android, Fastboot is also found on other devices, but this article will focus specifically on smartphones from Google. We will tell you why the mode can turn on, what it is, what it is for 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 the ADB command line, but sometimes special software is used for this.

Here are the most common Fastboot Mode commands:

• Flash is a firmware mode that overwrites the device's memory, which stores the Android operating system.
• Erase - erasing a section or the entire file system as a whole. Needed for a "clean" installation of the OS.
• Reboot is 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 put into Fastboot Mode to be recognized by a computer or laptop, you need to install special drivers on Windows, which are released separately for a particular phone model.

What is it for

Now you know what it is, all that remains is to explain where and why this mode is used. The access technology in Fastboot is used in the following cases:

• Firmware for Android phones.
• Operating system update from Google.
• Elimination of errors caused by failures in the OS.
• Editing system files (I mean exactly 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: you cannot change the Android phone identification number (IMEI) 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 boot" mode on his gadget.
• The firmware crashed, as a result of which the operating system can no longer boot normally.
• A signal to start the mode was received from the computer with USB debugging enabled.

If a black screen with a debug image appears in front of you, do not be alarmed. It is usually very easy to get out of Fastboot and boot into Android. Below we will show you how to do this.

How to exit Fastboot

There are several ways to disable Fastboot Mode. Let's consider each of them in more detail, for clarity, we will use step-by-step instructions, each stage of which is accompanied by a screenshot. Let's start with the simpler options, and only if they don't 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 is reset. 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, go to the next method of deactivating it. If your device has a removable battery, try removing it, wait a couple of minutes, and then reinsert it.

Important: the activation of 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 available in any Android phone.

Options for enabling Recovery on different devices:

If your device is not in the table, you can find the information you need on the network or ask a question in our Telegram group.

Through the reboot menu

So, when we get into the recovery mode, we need to do the following:

The example below is shown based on the Xiaomi Redmi Note 4x phone, but everything will look about the same in other models.

1. Go to Recovery.
2. Using the volume up and down buttons, select the reboot point to the system. The choice is most often made by the power button.

1. We are waiting for a reboot.

If it doesn't help, go to the next section.

Formatting internal memory

You can also try to turn off Fastboot on Android by formatting its internal memory. Below we will describe how this is done.

Attention! This method involves deleting all user data, including photos, videos, music, etc.

1. Run Recovery mode again and select Wipe All Data. We apply our choice and confirm it.

1. We confirm our intention.

1. We are waiting for the completion of the formatting of the internal memory, then we are waiting for the reboot to the main operating system. Please be aware that the first startup after a factory reset may take some time. Sometimes it is even 10 or more minutes. In this case, the smartphone seems to "freeze" on the power-on logo. You just have to wait.

Fastboot started again? Then read on.

Using a PC

This instruction will help out those who were not helped by the previous options. But it is she who has the greatest efficiency. Let's get started.

Attention: the instructions that you will find below are shown using the example of Xiaomi Redmi Note 4x and are provided for information only. If you have a different model, check the procedure for information from thematic forums.

1. We open Yandex or Google and write a request on our phone. We find the forum w3bsit3-dns.com and go to it.

1. In order to download files here, you must register. The procedure will take only 2 - 3 minutes.

1. First, we download the driver for Android Fastboot Mode.

1. Then we load ADB itself.

1. We unpack the driver into one of the folders that you need to create in advance.

1. We start the installation depending on the bitness of the operating system.

To check which Windows you have, use the Win + Pause / Break hotkey combination. In the line marked on the screenshot, you will see the architecture of your Windows.

1. We continue to install ADB to exit Fastboot. Here we just click on Next.

1. The installation will be over in an instant. Click the button marked below.

Let's move on to installing ADB.

1. Unpack the downloaded files to any folder you created.

1. Run the file marked in the screenshot.

1. Enter "Fastboot reboot" into the command line. Then press Enter.

Attention: at this point, the 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 and Fastboot on Android is still active, all that remains is to reflash the phone.

Firmware

Firmware is the last but most effective method to help your Android exit Fastboot. Before we continue, recall:

The instruction is given on the example of the smartphone Xiaomi Redmi Note 4x / 5x, for other gadgets, other options and the firmware themselves are used. By installing the wrong software, you run the risk of "killing" your phone.

Waiting for Device error

If you have a long time in the command window the inscription waiting for device- means:

• Driver not installed or incorrectly installed - reinstall or install
• Android device not in Bootloader mode - translate
• Incorrect connection to the USB port - use the rear USB 2.0 ports of the computer, do not use USB hubs

Android OS, like any other software product, can occasionally fail. And one of these problems is the display of a black screen on the screen of a smartphone or tablet with the inscription Fastboot Mode or Select Boot Mode. Many owners of mobile devices, seeing a similar picture, begin to panic and carry the device to the nearest workshop. However, you should not take rash actions, since in most cases you can exit the Fastboot Mod mode on your own. Let's take a look at what Fastboot Mode appears from, what it is on Android and how to get rid of it.

Purpose and causes of occurrence

Fastboot is an effective tool for modifying and customizing the Android operating system, which is included in the software developer's suite. Its main task is to install custom firmware. However, this bootloader is also used to install backups, various updates, format the memory card, etc.

Select Boot Mode and Fastboot Mode are not internal or external commands. They start earlier than the operating system itself (like the BIOS on Windows). This allows you to configure the system, as well as fix various problems even with a crashed Android.

Despite its versatility and usefulness, self-activation on a Fastboot mobile device may be a sign of a software failure. The main reasons for the appearance of this mode on Android include:

1. Accidental activation by the user himself. This tool can be launched manually via the gadget menu.
2. Android crash. If the smartphone or tablet cannot boot normally, it will automatically enter Fastboot Mode.
3. Unsuccessful firmware through.
4. Manual removal of the executable file from the system directory after unlocking root access.
5. Exposure to malware. If the device has superuser rights, some viruses can block or completely delete system files, which leads to a crash of the operating system.

Having figured out what the Fastboot Mode bootloader is and what are the reasons for its appearance, you can begin to consider the question of how to exit the boot mode on Xiaomi, Meizu, Lenovo and other models of mobile devices.

Disabling Fastboot Mode on Android

You can turn off the Fastboot bootloader in two ways:

• directly from the phone;
• via PC.

The choice of this or that option depends on the reason that led to the launch of this mode. As an example, consider how to prevent the Fastboot window from loading on a Xiaomi smartphone.

Faced with this problem, first of all try to hold down the Power key for 20-30 seconds. The device should restart in standard mode.

The Select Boot Mode form may appear on the mobile phone screen instead of Fastboot. Its fields mean the following:

Try to select the second item. If this does not help, do the following:

If you can go to the Xiaomi settings, that is, the operating system is working, try to disable the Fastboot mode manually. Go to the "Accessibility" tab on this device and drag the slider to the Off position in front of the corresponding item.

Disable Fastboot Mode via computer

When the operating system crashes, when it is technically impossible to use the smartphone menu, and other methods of disabling Fastboot are ineffective, you can try to solve the problem through a PC and the cmd command line. This is done as follows:

The command line is the most effective way to get rid of Fastboot Mode. If it does not solve the problem, that is, the question of how to turn on the mobile device in normal mode is still relevant, you just have to change the firmware on the phone or take it to the workshop.

Android firmware i.e. Writing certain file-images to the corresponding sections of the device's memory using special Windows-software, which almost completely automates the process, today is not the most difficult procedure from the user's point of view. If the use of such tools is impossible or does not give the desired result, the situation is saved.

In order to flash an Android device via Fastboot, you will need knowledge of the console commands of the device's operating mode of the same name, as well as a certain preparation of a smartphone or tablet and a PC used for operations.

Due to the fact that in the fastboot mode, manipulations with the device's memory sections are actually performed directly, when using the firmware method described below, some caution and care is required. In addition, following the steps below should probably only be recommended if there is no other way to flash the firmware.

Each action with their own Android devices is carried out by the user at his own peril and risk. For the possible negative consequences of using the methods described on this resource, the site administration is not responsible!

A clear implementation of the preparatory procedures predetermines the success of the entire process of flashing the device, therefore, the implementation of the steps described below can be considered a prerequisite before carrying out operations.

Installing Drivers

How to install a special driver for fastboot mode can be found in the article:

System backup

If there is the slightest possibility, before flashing it is necessary to create a full backup of the existing sections of the device's memory. The steps required to create a backup are described in the article:

Downloading and preparing the required files

Fastboot and are complementary tools from the Android SDK. We download the entire toolkit or download a separate package containing only ADB and Fastboot. Then we unpack the resulting archive into a separate folder on the C drive.

Through Fastboot, it is possible to record both separate sections of the Android device's memory and firmware updates as a whole package. In the first case, you will need image files in the format * .img, in the second - package (s) * .zip... All files that are planned to be used must be copied to the folder containing the unpacked Fastboot and ADB.

Packages * .zip do not unpack, you just need to rename the downloaded file (s). In principle, the name can be anything, but it should not contain spaces or Russian letters. For convenience, you should use short names, for example update.zip... Among other things, it is necessary to take into account the factor that Fastboot is case-sensitive in the sent commands and file names. Those. "Update.zip" and "update.zip" are different files for fastboot.

Launching Fastboot

Since Fastboot is a console application, the tool is operated by entering commands of a specific syntax into the Windows command line (cmd). The easiest way to launch Fastboot is to use the following method.

This add-in allows you to perform all operations from the examples described below in a semi-automatic mode and not have to resort to manually entering commands into the console.

Unlocking the bootloader

Manufacturers of a certain number of Android devices block the ability to manage the device's memory partitions by locking the bootloader. If the device has a locked bootloader, in most cases its fastboot firmware is not feasible.

To check the status of the bootloader, you can send the command to a device that is in fastboot mode and connected to a PC:

fastboot oem device-info

But again we have to admit that this method of finding out the lock status is not universal and differs for devices from different manufacturers. This statement also applies to unlocking the bootloader - the methodology for the procedure is different for different devices and even for different models of the same brand.

Writing files to sections of the device's memory

After completing the preparatory procedures, you can proceed to the procedure for writing data to the device's memory sections. Once again, we double-check the correctness of loading the image files and / or zip-packages and their compliance with the device being flashed.

Attention! Flashing incorrect and damaged file-images, as well as images from another device into the device, in most cases leads to the impossibility of loading Android and / or other negative consequences for the device!

Installing zip packages

To write to the device, for example, OTA updates, or a complete set of software components distributed in the format * .zip, the fastboot update command is used.

Writing img images to memory partitions

In many cases, the search for firmware in the format * .zip to download can be difficult. Device manufacturers are reluctant to post their solutions on the Web. In addition, zip files can be flashed through recovery, so the expediency of using the method of writing zip files through a fastboot is questionable.

But the possibility of flashing individual images into the appropriate sections, in particular "Boot", "System", "Userdata", "Recovery" and others through Fastboot when restoring the device after serious software problems, can save the situation in many cases.

To flash a separate img image, use the command:

fastboot flash partition_name filename.img

Thus, the firmware is performed using commands sent through the console. As you can see, the preparatory procedures take up more time and effort, but if they are performed correctly, writing the device's memory sections is very fast and almost always problem-free.

Hello. Some users of devices with the Android operating system sometimes encounter the "Fastboot Mode" notification after the next reboot of the smartphone. The most unpleasant thing is that it is not so easy to deactivate the mode, and if the device is simply turned off and on again, there will be no positive result. Let's see what Fastboot Mode is on Android, what it is for and how to correctly exit this "shell".

We are dealing with a very powerful tool that was previously part of the SDK (Developer Kit). The main purpose of the tool is to "reflash" the internal memory of the gadget in order to restore the factory parameters and delete all "unnecessary" data. In terms of its functionality, Fastboot is in many ways similar to the more well-known Recovery mode.

In addition, Fastboot allows you to install updates (both official and custom), which cannot be installed when the operating system is loaded.

It should be noted that this mode is not part of Android, but is located directly in the memory chip. This makes it possible to start the development environment even when the Android 5.1 OS is damaged. This is the main advantage - commands are executed at a low level, there is a direct interaction with hardware modules, bypassing the "operating system".

This functionality does not integrate into all devices, and is not supported by all smartphones or tablets.

What does Fastboot Mode mean on Android?

We figured out the essence of the concept a little, but it is also worth understanding why users switch to the specified mode after restarting the phone. Here are the main reasons:

• The most banal and common is the accidental simultaneous pressing of the power button of the gadget and the volume control key (sound-) when the device is turned off. Perhaps you just wanted to start the smart, but you accidentally pressed the volume down button, and Fastboot was activated;
• There was a not very successful attempt to update the software (flash Meizu, Xiaomi Redmi, etc.);
• You wanted to get root rights using third-party software (through a connection to a computer), then Fastboot Mode was loaded instead of root after restarting;
• A major crash has occurred in Android 6.0.

How to use fastboot mode correctly

• First, you need to connect your PC and smartphone via a USB cable;
• Fastboot Mode is activated on the mobile gadget. This option can be hidden in the screen settings or in the Accessibility section:

• Now you need to download and install the FastbootTool utility on your laptop (choose the latest version from the list on the official site);
• Open the software and if the previous steps are completed correctly, your tablet model will be indicated in the main software window;
• Now you can perform various actions with the device that are not available in normal mode. But I recommend that you carefully read the topic on the w3bsit3-dns.com forum, specifically for your phone model (ASUS, Lenovo, Huawei, ZTE, etc.).

Fastboot Mode for Android - how to get out?

So, you found yourself in Fastboot mode, but you do not know how to return to normal operation of the device. Here's a quick guide to help:

• Try holding down the Power key (on / off) for 30 seconds. In most cases, the gadget goes out, shows no signs of activity, and then suddenly starts up and everything is fine. The main thing is to wait and not remove your finger from the button;
• If the first method doesn't work, remove the battery (lucky if it's removable), set it aside for 5-10 seconds. Then put it back in place, close the housing cover and hold the power button for at least 20 seconds;
• In case of failure, connect your smartphone to your computer after downloading the drivers for your phone model. You can do this by following the link, on the right you will see the red form "Download Android Driver", where you select the manufacturer from the list, etc. Then on the PC you should open the console window (command line) using, and write the command:

fastboot reboot / code>

The tablet should force restart and the next boot will take longer than usual.

How to Exit Fastboot Mode - video

I tried to explain in detail what Fastboot Mode is on Android, why it is used, how to disable and exit the mode. Alas, some cases are individual. Therefore, if this kind of problem arises, I ask you to inform me in the comments.

Sincerely, Victor!

Sometimes, in phones or tablets running on the Android platform, Fastboot mode may turn on. This happens for various reasons, one of the most common may be an unsuccessful attempt to flash a Custom Recovery image. As a result, the device "freezes", a corresponding inscription appears on the dark screen, and no body movements can bring the device out of the stupor.

What to do in such a situation, how to get out of Fastboot Mode Android? However, first things first.

Fast Boot is a mode of operation of Android devices, in which the phone (or tablet) does not turn off completely, but continues to work in a "sleeping" state, and it turns on within five seconds. This mode allows a developer, or even a simple user, to flash, flash and restore the Android OS software shell. Getting Root rights to a smartphone can sometimes cause the mode to be turned on.

The "Fast Boot" is located in an area of ​​the device's memory that is inaccessible for reading or writing, which means that it is almost impossible to kill the phone programmatically.

The operation of the device in Fast Boot mode has little effect on the battery charge, but you will not be able to enter the welcome screen, which is loaded when the phone is turned on.

Fastboot Mode Android - How to Exit Mode

There are actually more than enough ways to solve the problem, they may differ depending on the gadget model, but we will now tell you about the most common ones.

First option... The standard solution for loading a smartphone in normal mode is to remove the battery from the device for a few seconds, then return it to its place and turn on the device.

Second option... If the previous solution didn't work, then try the following:

(For Android 2.3)

On the main screen, open the "Settings" menu (or Settings):

In the section "Applications" (Applications) find the item "Fast Boot" and uncheck:

We reboot the device.

(For Android 4.0)

In the "Settings", in the "system" section, we find the item "Special. opportunities ", we open:

It is quite possible that all these "let's go here", "open here", etc., you simply cannot perform - the phone simply will not respond, then you will need to do a full reset.

Important! As a result of this manipulation, all data will be deleted, therefore, once again it is worth recalling the need to make backups.

So what are we going to do:

Turn off the phone completely (you can remove and insert the battery again), take out the SIM card and SD-card. Press and hold the volume button (the increase or decrease depends on the phone model) and at the same time the power button:

• In the menu that appears after this manipulation, select "Recovery" (move through the items using the volume button, and confirm the choice of the action with the "Power on" button).
• When the Android logo appears, press and hold the power key, then the volume fan up.
• In the menu, select clear (wipe) data \ cache.
• After deleting the data, we select reboot, hold down and hold the power button, wait for the phone to reboot itself.

We'd be glad if this post helped you solve another problem. Otherwise, you can always contact our specialists. Good luck!

Some applications that were originally intended for desktop operating systems, some developers are trying to transfer to mobile operating systems. These include FastbootMode. What is it on Android, we will try to figure it out, and also describe all the features of this program for mobile devices.

Oddly enough, many users come across such an application, while there is no full-fledged article on the Internet about the description of functions and capabilities. Although in thematic forums, if you deal with this issue closely, in parts it can be collected in full.

With a literal translation of the name, you can draw certain conclusions about the functions and purpose of this or that software. Fastboot Mode is translated as fast boot mode. In fact, it is in the situation with the version for Android that the name can be misleading, because this application does not lead to faster OS loading, its main task is to flash mobile devices and it can be attributed to development tools. If the user is not too versed in such matters, in order to avoid trouble, when Fastboot Mode appears, it is better to immediately contact the service center so that the specialists unload this application from startup.

This program cannot be classified as Android. If it starts, then the operating system has not started yet, because Fastboot Mode refers to low-level applications, that is, they are loaded even before the OS starts.

The start of the software in question can occur for several reasons:

1. when turning on the phone, the user can, in addition to the power button, hold down the volume down button and hold it for a long time;
2. if before that a flashing was performed, during which there were failures;
3. root rights have been set;
4. system failure.

The fourth case is the most dangerous and, most likely, you cannot do without a trip to the service center.

After starting Fastboot Mode, the screen displays an Android icon with several menu items, which can be navigated using the volume buttons. To enter one of the points, you must press the power button.

To exit this mode, follow these steps:

• hold the power button for 30 seconds, after which the mobile device should boot up normally;
• if it is possible to remove the battery in the device, do this and do not insert it for 10-20 seconds;
• if the battery is not removable, hold down the power button and volume control at the same time. Hold them for one minute.

You can remove Fastboot Mode from autorun immediately after loading the Android OS. Go to settings and follow these steps:

• go to application settings;
• find the menu item "Fast Boot" (you can also find the name Fastboot Mode or Fast Mode) and uncheck it.

In some phone models the menu is different and this item may be located in a different place. In this case, go to Settings> Accessibility and also uncheck the above item.

If, even if the mode is disabled, when the mobile device is rebooted, Fastboot Mode is automatically launched, then, most likely, an incorrect flashing procedure was performed, or system failures occurred. In order to avoid troubles and not render the device inoperative, try to contact the service center as soon as possible, because mobile devices cost a lot and are incommensurate with the payment for repairing the software itself.

Android OS, like any other software product, can occasionally fail. And one of these problems is the display of a black screen on the screen of a smartphone or tablet with the inscription Fastboot Mode or Select Boot Mode. Many owners of mobile devices, seeing a similar picture, begin to panic and carry the device to the nearest workshop. However, you should not take rash actions, since in most cases you can exit the Fastboot Mod mode on your own.

Today we'll talk about the very necessary and useful Fastboot Mode system program. You will find out what this Fastbud mod is and what it is intended for. We will consider versions of this program on a laptop, tablet and smartphones.

Fastboot Mode on Tablet and PC

Fastboot Mode is a program that uses fast system boot technology. This technology allows to reduce the system startup time (x86) from seconds to milliseconds by bypassing the BIOS.

This technology was jointly developed by QNX and Intel. In general terms - PC control is fed directly to the primary boot module (QNX IPL) without using the BIOS. Thanks to this, critical tasks are launched with a minimum of delays.

Very often this technology is found on netbooks and laptops of certain brands (Lenovo, Asus, Aser) - when the laptop starts, the operating system starts loading almost immediately.

Fastboot Mode on Android smartphones

Fastboot Mode has a completely different meaning on Android devices. Here we are already talking about the mode, which is the “low-level” phone bootloader. Fastboot will allow you to reflash not only the entire phone memory as a whole, but also its individual sections.

Basically, Fastboot Mod can be observed after unsuccessful custom recovery phone flashing. When the phone is loaded, the black screen with Fastboot Mode and other commands:

Select Boot Mode;
Volume_UP to select;
Volume_Down is OK;
Recovery Mode;

Normal boot.

Many owners of their Android devices, not knowing what to do with this (considering it a mistake), panic. But here the matter is pretty fixable. For each model and brand of phone, the list of commands and their sequence is different, however, the principle is the same everywhere.

These commands mean the following:

• Volume UP button - to scroll through commands;
• Volume Down button - to confirm your choice;

To boot the phone, select Normal Boot and press the Volume Down button.

In order to independently call the fastboot mode, you need to simultaneously press the lock button with the volume key and hold them until a black screen appears. I hope you figured out what Fastboot Mode is and what it is used for.
