The Android mobile operating system is distinguished by its functionality, reliability and the possibility of deep management. Since user actions can sometimes cause more harm to the system than malicious programs, access to system functions is limited by developers. At the same time, experienced users often open root-rights to make changes in their own way, but do not forget that interfering with the Android environment without certain knowledge and skills is dangerous for the system. In addition to root-access, the Fastboot Mode offers a wide range of options, which exists separately from the operating system. The shell, comparable to the BIOS on computers, is part of the software for Android, this software component is used for debugging a smartphone, flashing it, and making other adjustments. Despite the high level of reliability, and on Android devices there are failures in work, so, sometimes users can observe a spontaneously activated fast load mode, for which the phenomenon of "self-starting" is not typical, so it may well signal a problem, although often the situation is one-time. Rebooting the device in this case is ineffective, but you should not panic, even if you absolutely do not understand what to do with this. Correct actions, following the instructions for exit from the mode will help solve the problem in a matter of minutes.

Work with Fastboot Mode in Android.

What is Fastboot Mode

In Russian, the name of this software tool sounds like “fast boot mode” and in the case of application on laptops, its task is to accelerate the launch of the operating system, bypassing the BIOS, and debugging software. The Fastboot component is not tied to a specific OS, but it is more common on Android, and here its functionality is different. In many ways, there is a similarity with the more popular Recovery. Speaking of Fastboot Mode, we will look at what it is on Android, since users are more likely to encounter this mode on smartphones and tablets. The Fastboot Mode tool is a system-independent software component that developers use to tune applications and reinstall the OS. In addition, the "Fastboot" features can be used by service experts and experienced users. Fastboot Mode in Android devices is implemented at the hardware level. The program code is registered in the memory chip, in a place protected from writing and reading, which means that it cannot be damaged.

The tool provides access to the system elements of smartphones and tablets to control them from a computer. In order for a PC or laptop device, immersed in this mode, to be recognized, it is necessary to install drivers to perform communication between devices corresponding to the smartphone model. Considering what Fastboot Mode is on Android, here’s a list of the main features available when a component is activated:

• Backup and restore system;
• Reinstall OSes;
• Change hidden system settings;
• Troubleshooting OS;
• Getting root rights;
• Installing components;
• Application recovery;
• Software testing, etc.

Fastboot Mode is launched before the firmware, it is autonomous, which means that the mode can be used even if it is impossible to boot the system or it does not work correctly for serious failures.

When does Fastboot Mode activate?

A fastboot can be launched in various ways, through a standard menu or by simultaneously pressing the power and volume buttons, but spontaneous launch is often a bad sign. The following factors can provoke self-loading Fastboot Mode:

• System failure;
• Random activation mode by the user;
• Unsuccessful attempt to flash the device using Recovery Mode;
• Connecting via USB to a computer with the “Quick power on” option activated;
• Getting root-rights using third-party software;
• Removal of system executable files by the user subsequently illiterate use of root-rights;
• The influence of malicious programs that can damage or remove system elements, which is not excluded if you have extended user rights.

The user who intentionally immersed the device in the "Fastboot", certainly understands how to work with the functionality and performs actions depending on their plans. But what to do if Fastboot Mode is activated by accident. Let us consider how to correct this situation, when a picture appeared with a picture of an opened robot, symbolizing Android, as well as the system data of the device.

How to exit Fastboot mode

As already mentioned, restarting the device is often useless, including removing the battery. The reboot is triggered if the tool is accidentally activated. As a rule, it is unlikely that you will remove the device from these modes, but there are effective ways by applying one of which you can return to normal work after leaving the Fastboot environment. Depending on the reason for the device to be immersed in Fastboot Mode, the ways to get out of this mode differ, you can perform the procedure through a smartphone or using a computer.

Normal mode

First of all, you should try to choose a normal device load, for which the following actions are performed:

• Turn off the device and simultaneously hold down the power and volume buttons, hold down until the Select Boot Mode menu appears or the OS is loaded normally (about 10 seconds);
• In the menu, scroll through the items using the volume up button;
• Select Normal Boot by applying the volume down button.

During normal operation, the device will turn on and load the Android OS. In some cases, users notice the download mode after the interaction of the smartphone with the computer, and nothing prevents to perform any actions, the problem occurs when disconnecting from the PC. Often the phenomenon is associated with disabling the option, for example, by service specialists after working with the device. You can fix this by:

• Go to the settings after a normal boot;
• In the "Screen" or "Special Features" section, uncheck the "Quick Download" option.

Recovery mode

To restore the device back to normal, you can use the Recovery mode, which allows you to reset to factory settings, back up data, update the firmware, and other actions without booting the system. Recovery involves formatting all data, that is, returning the device to an out-of-box state, so it’s best if you have a copy of it. To implement the procedure, do the following:

• We activate the mode by holding down the power button and increasing or decreasing the volume (depending on the model of the smartphone), we wait for the download;
• First of all, you should try to boot from here in normal mode, for which choose “Reboot”;
• If it didn’t help and the device went back into Fastboot Mode, activate Recovery and select “wipe data / factory reset” in the main menu;
• We are waiting for the task to complete, then a reboot will follow.

The method helps in most cases, but the minus is that you have to reinstall the applications you need and return the device to its usual form, download the backup (if available), because after the reset everything will look the same as when you bought the device.

Exiting Fastboot using a computer

To exit from “Fastboot” using a PC, you need the appropriate drivers that are suitable for the device model. It is better to download software from official resources in order to avoid penetration of malicious programs with files. So, do the following:

• Unzip the downloaded firewood to a folder;
• We connect the smartphone to the PC using USB;
• From the Control Panel (or in any other way) call the Device Manager;
• Select the item “Other devices” and click PKM on “ADB Interface”;
• We select from the menu item “Update drivers” that appears in the menu, by pressing the corresponding button, perform a search on the computer, indicating the path to the directory where we unzipped the firewood. Now the device will have to change the name from “ADB Interface” to the name of your device.

After installing the appropriate drivers perform the following steps:

• Open the Run console on your computer (in any convenient way, for example, using the Win + R keyboard shortcut);
• In the command line, enter fastboot reboot, confirm the action, after which the smartphone will reboot and exit this mode.

If none of the methods helped in solving the problem, a flashing of the device is also possible as a cardinal measure, but, as a rule, the solutions described above cope with the task.

How to switch your phone to Fastboot Mode

Sometimes the user is required to use the “Fastboot” functionality for the purpose of flashing, updating with ADB or other reasons. Activating Fastboot Mode is easy:

• Turn off the smartphone;
• Use the combination of the power keys and reduce or increase the volume (for different devices may differ), hold them simultaneously until the menu appears, about 10 seconds;
• In the corner there will be an inscription "Fastboot Mode" or a disassembled robot.

Now you can perform the necessary actions by connecting your smartphone to a PC. Exit from the mode is performed if you select Normal Boot from the menu.

The above methods allow you to enter the "Fastboot" mode, as well as exit it, which is more often the concern of many users who are faced with the problem of spontaneous launch. The non-advanced user will be able to perform the necessary actions, since they do not differ in complexity, but it is important to carefully approach the task.
