Select boot mode from what arises. Fastboot Mode on Android - what is it? How to exit Fastboot

In our instructions for flashing and unlocking the bootloader, “fastboot mode” is often mentioned (translated into Russian “fastboot mode”). What is fastboot, where to download and how to use, we will tell you in this material.

What is fastboot mode

This is the software embedded in the Android device, which allows it to be controlled from a 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:

1. Protocolin the form of a bootloader control system from a computer.
2. Softwarethat works on the device in fastboot mode.
3. Executable file on a computer, which is used to interact a mobile device with a computer.

Usually, when you see the action in the instructions: "load smartphone into fastboot", "reboot into fastboot" or "go to fastboot", this means launching this mode on the mobile device for further interaction with the computer.

Almost all smartphones and tablets support the fastboot control protocol. The exception is some manufacturers of 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 exit fastboot mode

There are three ways to exit fastboot mode:

1. By entering the fastboot reboot command.
2. By holding the power button for 15-20 seconds.
3. Removing the battery.

If the device is in fastboot mode, and you are finished and want to load 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 is also helped 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 will not work if the button is damaged.

A barbaric, but in some cases effective way is to remove the battery, if such a possibility is provided by the design. After returning the battery back, the phone will boot the OS by pressing the power button.

Fastboot purpose and capabilities

The fastboot protocol is designed to restore a device in case of deletion or incorrect firmware, one or all partitions, including recovery. Therefore fastboot comes in handy when other methods fail.

A list of some of the operations performed via fastboot:

• Transfer to fastboot mode.
• Status check and factory.
• , kernel, or other section.
• Delete or format a specific section.

Conclusion

What is fastboot mode (fastboot 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 a failed firmware, since fastboot will not go anywhere even if all partitions are deleted. Moreover, any system recovery process is easier if the bootloader is in an unlocked state.

Fastboot Mode is a software package that is needed to debug applications, to quickly boot the system and to flash low-level firmware. Fastboot Mode is also found on laptops, in models such as lenovo, asus and others. And on devices with the Android operating system, on smartphones, tablets. So we briefly learned Fastboot Mode what it is on android.

This component is used in different ways if you compare a smartphone and a laptop. If on a laptop Fastboot is used to quickly boot the system bypassing the BIOS system, then on a smartphone this component makes it possible to get into the operating system, so to speak, a semblance of root rights.

Fastboot Mode what is it

In this article, we'll talk specifically about Fastboot Mode for Android. Not everyone understands why this function is needed and how to use it and whether it should be used at all, for what cases it is needed.

Fastboot gives you the ability to get full access to the system through your computer, without any restrictions. Thus, you can get root rights, flash the device, configure its parameters and install the application.

But there are times when this function was called by accident and after reboot Fastboot still appears.

Fastboot Mode how to exit

Although this function is useful, it happens that the window appears and does not want to be removed. This window looks almost the same on all devices. There is information about your device, and some menu items.

There are several options for what reason you ended up in Fastboot:

• You pressed the lock key and the volume key at the same time (on some devices, the key combination may differ)
• System failure device

If you somehow got into Fastboot Mode, then the first thing you need to check is that you can go into normal operation and there are no problems in the system. To navigate the menu, we will use the volume key. By pressing the up key, you will navigate, by pressing the volume key down, you will select the active item. We are interested in the item "Normal Boot", move to it with the up key, as you will at this point, press the down key.

such a problem occurs if the function was turned on to work with a computer or if you gave the device for repair, then you simply forgot to turn it off. It doesn't matter why it happened, you can disable the fastboot this way (if it's not a system failure)

So that this window does not bother you, you can easily disable it in the device settings.

To turn off Fastboot, you need:

• Open the "Settings" menu;
• Select the "Screen" section;

This way you disable Fastboot, and if necessary, you can enable it in the same way. You just need to check the box.

Fastboot Mode on system crash

In this case, disabling Fastboot Mode loading is much more difficult or even impossible, because there is no access to the Android system and there is no way to load it due to a failure. To deal with this problem, you need to completely format the device. It is better to remove the sd card, if there is one. All data from the device will be deleted.

To completely format the device, you need to go into recovery mode. To do this, you need to hold down the volume key up or down, depending on the device, and the power button.

It may be necessary to reflash the device after such an operation, but this is rare. After this operation, your phone will be reset to factory settings and the download should proceed in normal mode.

You should not immediately resort to this method, use it as a last resort when other methods have not helped.

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, Fastboot saves the situation.

In order to flash an Android device via Fastboot, you will need knowledge of the console commands of the device 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 attention 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. The site administration is not responsible for the possible negative consequences of using the methods described on this resource!

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

You can learn how to install a special driver for fastboot mode from the article:

System backup

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

Downloading and preparing the required files

Fastboot and ADB 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 individual 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 and Russian letters. For convenience, short names should be used, 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 series 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 state 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 memory sections of the device. 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 image files, 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 recovering 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, the writing of the device memory sections is very fast and almost always problem-free.

Smartphones on the Android platform are the most common among users and this is largely due to the availability of these gadgets. There are times when, when the device is turned on, the owner sees animation and data in which he does not understand anything, all this is perceived as a malfunction of the device, a system failure, and so on. It is at this moment that smartphone users have a question: and what to do with it, in general. Let's try to understand the issue and clarify the situation in as much detail as possible.

Fastboot Mode, what is it on Android

What I want to clarify right away, the application belongs to the system and it will be quite difficult for a little experienced user to figure it out. A simple reboot of the device will not help and the gadget will return to its original position, therefore, we still advise you to understand the issue in detail and act in accordance with the recommendations so as not to harm your smartphone.

Fastboot Mode is used not only on the Android platform, but also on laptops. In the latter, the process is designed to speed up the loading of the operating system or debug the necessary software. In Android devices, Fastboot Mode provides full access to the gadget for performing certain actions from the PC. Thanks to it, it becomes possible to update or change the firmware, install applications and debug existing programs.

The process is found in different programs, for example, in the SDK environment, it is responsible for the high-quality interaction with the computer. It starts up earlier than the standard operating system and allows manipulations at the software level. In this connection, the mode is very useful, but in inexperienced hands it can lead to undesirable consequences.

In this connection, the mode starts

And so, above we found outfastboot Mode, what is it on Android. Again, it is very useful and allows you to make adjustments at the program level. But if you have not activated it and you do not need deep settings, and the window appears, a lot of questions arise. Many may think about the worst and go to the service, but do not panic ahead of time, let's first try to cope on our own.

The accidental pressing of a certain key combination can become the reason for the willful start of the engineering mode. This can easily happen in a pocket or simply if the user unsuccessfully grips the gadget in his hand. The most common combination is "power button and volume key +", but pressing them provokes the start of the mode only if the smartphone is turned off, a working gadget in an identical situation will simply take a screenshot of the screen.

Another reason is a system failure or an error in the firmware, this is already a more serious case and solving the problem will require certain actions, which we will consider below. In addition, the mode starts when, but in this case, the user most often understands what he is doing and what caused the launch of Fastboot Mode.

What to do when

So, you found that your smartphone launchedfastboot Mode, what is it on Android we have already found out, it remains to understand how to deal with it if your plans did not include deep work in the system.

If the gadget is working properly

First of all, it is worth finding out if the gadget is working normally. To do this, simply turn off the called Fastboot Mode. This is quite easy to do if you understand the basic principles of navigation. The volume key is used for work. One is used to select a menu item, the other scrolls through the list. To switch to a familiar operating system, scroll through the list until the selection marker is on the NormalBoot item, then click on the choice. As a result of the actions taken, the gadget should load the Android shell and open the familiar interface.

If this happened, then the smartphone is fully functional and the appearance of Fastboot Mode is a consequence of the owner's negligence or the carelessness of the master, in the case when the device was being repaired. To prevent the situation from repeating, it is enough to disable the function. To do this, in normal use mode, go to the smartphone settings and in the "Screen" section of the menu, find the "Fast Boot" item and uncheck it. This will deactivate engineering mode and it will not start every time you try to turn on the device.

System crash

In the case when an attempt to start the OS does not end in success, we can safely assume that a system failure has occurred. If you are in doubt and are afraid of harming the device even more, then it is better to take it to a service center, where the smartphone will be restored by professionals.

But you can try to cope with the problem yourself. The first thing an owner can do is try to restore the system. It should be noted that during this process, data is deleted and all drives are formatted, therefore, if there is valuable content on the memory card, it is better to remove it. Then hold down the power button at the same time, the volume key "+". In the menu that appears, select wipe data / factory reset and start the process. Wait for completion and reboot. After that, you will have to download and install the applications again and configure the smartphone for yourself, since its settings will return to the factory settings.

If the previous option did not work, you can go to heavy artillery and try to restore your smartphone via a computer. To do this, you will have to disassemble the gadget and completely deprive it of power, removing the battery for a while.

Then you need to download a driver from the Internet that is suitable for working with your smartphone model. Try to download and install software only from trusted and reliable resources to avoid problems with your computer as well. You also need to download a suitable version of the OS for your smartphone, unpack it and place it in the folder of the same name in a convenient place for the user. After the desired program is installed, connect your smartphone to your computer via USB. Wait for the software to recognize the gadget and select the "Install from a specified location" command, specify the path to the location of the downloaded operating system and start the process.

As soon as the gadget returns to working state, turn off Fastboot Mode in the settings, relying on the algorithm described above. That's all, the described method is the most effective of all those listed above, but it should be used only as a last resort.

Fastboot - A mode designed to improve download speeds in laptops and Androids does not always function properly. In other words, Fastboot Mode can crash. Although this phenomenon is rare, it still occurs. In cases where the mode, as they say, works to its fullest, it provides the following capabilities:

• Operating system loading rates are greatly accelerated by disabling third-party applications when loading.
• The electronic device starts to work more smoothly, without braking and freezing.
• Performing various operations in Android is greatly simplified.

What is Fastboot Mode in Android

Fastboot Mode is a fast boot function designed to quickly launch the operating system in Android and laptops. It is also used for firmware or software debugging purposes. Translated Fastboot Mode means "fast boot mode". Each computer manufacturer has its own specific constructive system for Fastboot Mode. As for Android, regardless of the brand, this function has practically no differences.

However, this mode is not always beneficial. It happens that a way out of it is required.

How to get out of Fastboot Mode Android

Disabling Fastboot Mode on Android is necessary in the following cases:

1. If the mode is accidentally activated as a result of a settings failure;
2. In case of malfunctions of the electronics itself. Sometimes you can't do without
   flashing the device.

What to do with Fastboot Mode in such cases?

Before you start taking measures to disable this mode, you should first make sure that there is a problem in your Android or laptop. To do this, you need to restart the operating system on the device.

If the mode is detected, Fastboot Mode will appear on the screen when turned on. This is where you should disable
Fastboot Mode function.

Disable Fastboot Mode in Settings

Although Fastboot Mode on Android is effective for quickly launching the operating system, all users need it. For example, if a smartphone or laptop is used occasionally and its frequent restart is not required, it makes sense to disable this function completely and permanently. This is done very quickly and easily:

If necessary, the mode can be easily reconnected.

Exit Fastboot Mode in case of system failure

This procedure is performed as follows:
The easiest and most common way is to remove the battery from the electronic device and insert it back in 10 seconds and turn on the smartphone again. Often, the device restores its normal load after performing such simple actions.

The steps described below are the same as for a factory reset! Use them at your own peril and risk!

To reset the settings, use the "Recovery" menu on the device.

Conclusion

I hope you figured out what Fastboot Mode is in Android systems and you know what to do if the device boots itself in this mode.
Fastboot Mode is often useful for full and wide access to a tablet or laptop, or when an operating system malfunctions. Here is a quick summary of what Fastboot mode is on Android.
