Fastboot mode is a special program code or component located in the memory chip of Android devices, i.e. he is independent from operating system Android and can be called even if there are problems with the system itself. Using Fastboot mode (translated into Russian as fast boot mode), the following series of tasks are performed:

• gaining access to Android system components;
• recovery and backup data on the device;
• opening root access on the device;
• changing system settings of the device, which under normal circumstances are hidden from users;
• software testing by developers;
• software recovery;
• flashing the device;
• and much more.

As you can imagine, Fastboot Mode is an extremely powerful tool that can be used by both developers and ordinary users. However, most often information about this mode is sought by users who have had this mode activated out of the blue on their device. Let's take a closer look at activating and exiting Fastboot mode.

How to enter/exit Fastboot mode on Android

So, first we need to understand for what reasons Fastboot mode can be activated at all. This mode is activated due to:

• pressing a combination of the power and volume keys (either + or -);
• a serious failure occurs in the Android OS;
• unsuccessful firmware on the user's part
• connecting the device via a USB cable to a computer with the “Quick Start” function activated;
• obtaining root access.

Unfortunately, simply rebooting the device often fails to get out of fast boot mode, and therefore you have to use slightly more sophisticated methods. However, you can try and reboot first.

The note: among other things, the fastboot mode screen may display a huge “Start” button (or the “Normal boot” item), clicking on which should start your device in normal mode- Click this button if available.

If it doesn’t help, then try removing the battery from your Android smartphone for about thirty seconds, and then turning it on again. For users of old smartphones this decision helps, however, on new devices this solution is simply not applicable: the battery of modern mobile phones- non-removable.

Ok, the next thing you can try is to enter Select Boot Mode and start the device in normal mode. So, turn off your smartphone and then hold down the Power and Volume Down keys for ten seconds. A screen with various actions will appear on your device's display - select Normal Boot. Once you select this option, your device should boot normally into the Android operating system.

Another way to exit Fastboot mode is to use a handy computer. First, you will need to install a combination of ADB + Fastboot on your computer, then connect your smartphone to your PC using regular USB cable. Once everything is done, open command line and run the fastboot reboot command, after which your smartphone will reboot and successfully exit the corresponding mode.

Well, if you were unable to start your gadget in normal mode even after doing all of the above (and this happens), then you will need to perform full reset of your device through recovery mode. Press the combination of the power and volume up buttons, and then wait until the recovery mode appears. Click “wipe data/factory reset” in the list and select it. The process of resetting your device may take some time, so you will have to be patient. After the reset, your smartphone will return to normal mode.

What should I do if my smartphone enters Fastboot mode when connected to a PC?

Another interesting topic: some Android smartphone users complain that their devices, for some reason, enter fast boot mode on their own when connected to a PC via a USB cable. Well, if this happens, then you probably have the “Quick Start” option activated in your smartphone settings. You need to disable this option and everything will fall into place. To do this, do the following.

Despite all the usefulness and versatility of Fastboot Mode, its spontaneous activation on Meiza may indicate serious problems with the operation of the mobile device. Fastboot is an indispensable tool for Android OS developers and debuggers. Ordinary users encounter it extremely rarely. Let's figure out what Fastboot Mode is on Meizu and how to exit this area if the phone is frozen and does not respond to external commands.

Purpose and reasons for downloading Fastboot Mode on Meiza

Fastboot is software environment, which is designed to restore and remotely configure smartphones running Android OS. It is included in the package of components for Android SDK developers and allows you to fully control your mobile device via a computer.

The main functions of Fastboot Mode Meizu M5, Meizu M2 Note or any other device are:

• installation of licensed and custom firmware on Android via PC;
• unlocking root access;
• creating and installing system backups;
• setting up gadget parameters that are not normally available to the user;
• restoring the performance of Meizu M5 Note after it has turned into “”.

Fastboot on a mobile phone is not part of the operating system and loads earlier than Android. The specified area is registered at the hardware level and is located in the memory chip. This allows you to work with it even if the operating system crashes.

Activation of Fastboot Mode on a Meizu phone may occur for the following reasons:

Disabling Fastboot through standard Meizu settings

There are three ways to turn off Fastboot Mode on Meizu M5:

1. . It is used when the operating system responds to mechanical keys and the user can enter the device menu.
2. Via computer and command line. Allows you to restore normal operation of the gadget if USB debugging is activated on it.

To prevent Meizu Fastboot from appearing the next time you turn it on, open the device settings and in the “Accessibility” section deactivate the “Quick Start” function.

Disabling Fastboot via computer

If, after these operations, the phone does not exit Fastboot, but USB debugging is enabled on it (for example, before this you installed custom firmware), you can achieve what you want via a PC:

After restarting, the phone should turn on normally. To prevent Fastboot from opening again, it is better to deactivate fast boot in its settings.

Fastboot mode (fastboot) allows you to flash your smartphone, install custom recovery, and also unlock the bootloader. It is also used for application development. There are times when the phone gets stuck in this mode and cannot boot.

How to determine that a smartphone is in fastboot mode?

On all smartphones it looks approximately the same: information about the phone model is displayed on a black background. Some people confuse it with Recovery menu, but distinguishing them is not difficult at all. In our case, there should be an inscription on the screen fastboot mode start udc_start().

How could the fastboot be activated? It is quite possible that when turning on you accidentally pressed the power key + volume down.

3. Select “Wipe & Reset”
4. All data will be erased from the device and it will return to factory settings.

Save all valuable data in advance, or even better, use a cloud service

To be able to fine-tune OS and hardware parameters, users of mobile devices under Android control sometimes they root their gadgets and also make changes to . But these are not all the available ways to gain expanded access to device and system settings. You can look under the “hood” of the device using a mode called Fastboot Mode.

What is Fastboot Mode

What does Fastboot Mode mean and what does it have to do with fine tuning? In some laptop models, it really serves to maximize system boot speed, bypassing the BIOS and debugging applications; in mobile devices, its purpose is somewhat different. On smartphones and Android tablets This mode is necessary primarily to provide access to and control of the system components of the device using a computer.

Using the capabilities of Fastboot Mode, service center specialists and experienced users can install software, flash the gadget, restore applications, perform backups and restores, and change hidden system settings. Developers often resort to “fast loading”, using it for software testing and other purposes.

Having explained the purpose of the mode, it seems that we still haven’t answered the question of what Fastboot Mode essentially is. So, fastboot in Android is separate, independent from the operating system software component, implemented at the hardware level and registered in the memory chip. It is this independence that allows the device to boot even if serious problems occur with the operating system. Program code Fastboot Mode is located in a memory area that is protected from reading and writing, which prevents damage to it.

In what cases is Fastboot Mode activated?

The Fastboot environment can be launched manually through the standard menu or by simultaneously pressing the power button and the volume down/up key on the switched off device. But in some cases the mode starts on its own, and this is not a very good thing. The reasons for spontaneous loading may be unsuccessful flashing, replacement of the standard recovery environment with a modified one, gaining superuser rights, system failure and damage to Android OS files.

How to exit Fastboot mode

The activation of the mode is indicated by the image of the opened robot and the inscription on the phone screen Fastboot Mode.

If you have not made any changes to the gadget’s configuration before, perhaps the reason for switching to “fast boot” was some kind of temporary glitch. Try restarting your smartphone. If even after a restart the phone says fastboot and does not switch to normal operating mode, this may indicate deeper problems. It is possible that the problem will turn out to be so serious that the gadget will have to be reflashed at a service center, but until it comes to that, you should try to exit the fastboot yourself.

There are two main ways to do this: through the phone itself and using a computer. If a normal reboot does not help, turn off the device, and then simultaneously hold down the power and volume down keys until (about 10 seconds) the Select Boot Mode menu appears on the screen or the phone boots up in normal mode. In this menu, select the Normal Boot option and wait for the gadget to boot in normal mode.

In some cases, removing the battery helps to exit the debugging mode, if it is, of course, removable.

Sometimes users have to deal with loading in fastboot mode after they have taken the gadget from service center. This usually happens after. Probable Cause– left the fastboot mode function enabled in the settings. If this is the case, then to disable Fasboot Mode, go to the settings, and then in the “Display” or “Accessibility” section, find the “Fast boot” item and uncheck it.

How to exit Fastboot Mode using a computer? Install applications on your PC, connect your phone to the computer, activate USB debugging, run the command line as administrator and run the command fastboot reboot. It's simple but very effective method disabling fastboot.

If this does not solve the problem, reset the device to factory settings. After copying all important data, remove the SIM card and memory card from the phone, boot into Recovery mode, find the option in the menu Wipe data/factory reset and perform a rollback using it.

Additionally, you can clear the storage contents by selecting the option Wipe cache partition.

How to put your phone into Fastboot Mode

Fastboot Mode is a service mode that you most often have to resort to if you need to change the device configuration via a PC, for example, install modified firmware or get root rights without use third party programs. Uploading in fastmode may also be necessary to provide full access to system folders Android and OS recovery (as an alternative to Recovery mode tools).

Login method Fastboot mode Mode on different devices may vary. In Asus smartphones, for this you need to hold down the power and volume up buttons, in Nexus and HTC - the power and volume down buttons, in Sony, the fastboot mode will load if you hold down the volume up and connect the gadget to the PC via USB.

But there is also universal method downloads to fastboot, which works equally on all mobile devices Android devices. Download and install the program on your computer Adb Run . Next, enable USB debugging in the phone settings, connect the device to the PC and, having launched Adb Run, select from the menu Reboot – Reboot Bootloader.

The gadget will reboot in Fastboot mode.

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

Purpose and causes of occurrence

Fastboot is effective tool on modification and adjustment of the operating room Android systems, which is included in the software development kit. Its main task is to install custom firmware. However, this bootloader is also used to install backups, various updates, format a memory card, etc.

Select Boot Mode and Fastboot Mode are not internal or external teams. 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 if Android has crashed.

Despite its versatility and usefulness, turning on Fastboot on its own 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. This tool can be launched manually through the gadget menu.
2. Android malfunction. If a smartphone or tablet cannot boot in normal mode, it automatically switches to Fastboot Mode.
3. Unsuccessful firmware via .
4. Manual removal executable file from the system directory after unlocking root access.
5. Exposure to malware. If you have superuser rights on the device, some viruses can be blocked or even removed system files, which leads to the 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 boot mode on Xiaomi, Meizu, Lenovo and other models of mobile devices.

Disabling Fastboot Mode on Android

There are two ways to disable the Fastboot bootloader:

• directly from your phone;
• via PC.

The choice of one option or another depends on the reason that led to the launch this mode. As an example, let's look at how to prevent the Fastboot window from loading on a Xiaomi smartphone.

When faced with this problem, first try holding down the Power key for 20-30 seconds. The device should reboot in standard mode.

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

Try choosing the second option. If this does not help, do the following:

If you can go to Xiaomi settings, that is, the OS is working, try to disable the Fastboot mode manually. On this device, go to the “Accessibility” tab and opposite the corresponding item, drag the slider to the Off position.

Disabling Fastboot Mode via Computer

If 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 command cmd line. This is done as follows:

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