Hello everyone Today we will talk about what is Fastboot Mode on Android. It seems that there is such a thing on a computer, but today we will consider Fastboot Mode on Android. So, I’ll say right away that there is a lot of information on the Internet, but all of it is somehow scattered across different sites, not all of it is understandable, so my task today is to collect all the information, filter it, leave the necessary and write it all to you here. This is the one I chose not an easy task

First, let's deal with the name, Fastboot Mode what does it mean? The first word Fastboot consists of two words, fast and boot, and means fast and boot. The second word Mode is taken by some users as the concept of fashion, but this is not a mod at all, it means mode in English. Therefore, wherever you meet the name Fastboot Mode, know what it means like fastboot mode

As for Android, there is such an unpleasant situation there, the user turns on his device and then he sees the inscription Fastboot Mode, well, the user thinks everything is a disaster, this is a mistake .. rebooting the device in this case does not help .. Although in reality , as you already understood, Fastboot Mode is no mistake!

As I already wrote, Fastboot Mode translates as fast boot mode. In principle, it is so, but not quite. Fastboot Mode is out of the world android development, and the main task of this mode is flashing the smartphone. There is also a Recovery Mode, this is already a recovery mode. Also, Fastboot Mode is used, so to speak, for service purposes, that is, for installing system modules, updates, patches, and performing some settings .. In general, we can conclude that all this is not for ordinary users, but for more advanced ones. For these modes can be both useful and dangerous in inept hands.

Fastboot Mode does not apply to the Android operating system, that is, if it is running, then this means that Android itself has NOT STARTED yet. For Fastboot Mode starts BEFORE the operating system. This behavior in the world of programming is called low level.

Not all Android phones support Fastboot Mode

Let's imagine that you turned on your phone and then bam, you see the inscription Fastboot Mode, what should I do and why did it appear? So the entrance to this mode could be performed for several reasons, these are:

1. random entry, this rarely happens, but it still happens, this is when the user accidentally pressed the volume down button and the power button and this activated Fastboot Mode;
2. I also found out that this mode appears after the wrong Custom Recovery firmware;
3. setting up root access;
4. if you didn’t do anything like that, then maybe the most terrible and incomprehensible thing is a system failure; often in this case, the most reasonable option would be to go to a service center;

This mode is easy to recognize, because as a rule, the Android symbol is displayed (some kind of robot) and its lid is open, all this hints at open access to the insides of Android. In principle, the way it is, and that is why I DO NOT ADVISE JUST GOING INTO THIS MODE AND DOING SOMETHING THERE. Moving between items is done using the volume rocker button. Selecting an item, that is, to click on it, you can do this with the power button. It might be something else top button the volume rocker is the movement in the menu, and the bottom button is the choice in the menu, depends on the smartphone

In practice, Fastboot Mode is used in this way, you connect the phone to the computer via a USB cable, then start Fastboot Mode on the phone. Open on the computer special utility Fastboot Tool, which is needed to send commands to the phone. The Fastboot Tool will be able to send commands provided that the phone is in Fastboot Mode, the only way.

Some smartphones allow this mode to be disabled. To do this, you need to go to the settings:

Then go to the Applications / Application Settings section and there find such an item as Fast Boot (it can also be referred to simply as Fastboot Mode or Fast Mode):

The setting may be in another place, well, on some models it's Settings> Display> Fast loading, on others it's Settings> Accessibility:

And probably you will have a question, how then to get out of Fastboot Mode? So see what to do:

1. hold down the power button and hold it for half a minute, the smartphone should reboot and boot normally;
2. take off back cover from the phone, disconnect the battery (if at all possible), wait ten seconds, and put the battery back; then hold down the power button for half a minute;
3. if you can’t remove the battery from your phone / tablet, then you need to put it like this: press the on / off button and the volume buttons at the same time, this is how you need to hold for a minute;

Another option is to reboot using a PC. To do this, you need to download the FastBoot utility, then you need to execute the fastboot reboot command. But I don’t write anything detailed on purpose, because I really don’t know how to make this command myself, but if anything, then you look on the Internet, there are people who understand Android better than me

My advice to you, if you have little knowledge in the field of Android, if the phone is dear to you, or maybe just not cheap, then I strongly recommend that you contact the SC. They will definitely help you there and the main thing is that there are certified masters who are responsible for what they do. In other words, there is at least some guarantee that the smartphone after the SC will continue to work!

That's all guys, I hope I succeeded in simple words explain to you what is Fastboot Mode in Android, now you know. And I hope that if you have such a misfortune that when you turn on the phone there is an inscription Fastboot Mode, then I hope that you can get rid of it yourself and suddenly my advice will help, then I would be VERY HAPPY FOR THIS. Well guys, it's time to say goodbye, until we meet again

Having explained the purpose of the mode, we seem to have not given an answer to the question of what Fastboot Mode is in essence. So, a fastboot in Android is a separate software component independent of the operating system, implemented at the hardware level and registered in the memory chip. It is this independence that allows you to boot the device even if there are serious problems with the operating system.

But in some cases, the mode starts on its own, and this is not a good point. The reasons for spontaneous loading can be unsuccessful flashing, replacing the standard recovery environment with a modified one, obtaining superuser rights, a system crash, and damage to Android OS files.

Probable Cause- the fastboot mode function left 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 "Quick Boot" item and uncheck it.
