Not every owner of a mobile device in the form of a smartphone or tablet running the Android operating system knows that any version of the OS has such a thing as Bootloader. What it is, now and will be considered. Based on an understanding of the very essence of the issue, it will be possible to find out what operations can be performed when it is unlocked.

Bootloader: what is it?

Let's start, so to speak, with the basics. Bootloader for Android systems is practically no different from what is available on any computer terminal, whether it's a PC or Mac. In simple terms, Bootloader is a built-in download tool

If we take as an example computer terminals with several installed “OSes” (say, Windows and Linux), the bootloader, after turning on the stationary unit or laptop, offers the user to log in to the system to choose from, and after confirmation loads one or another OS.

OS Boot Principles

As well as in stationary systems, in mobile devices it accesses initialization files in the same way as, for example, Windows does when loading parameters from the boot.ini file.

If you pay attention to just such data, it is easy to conclude that in Android systems you can easily change not only the boot method, but also the bootable OS, either manually or automatically. However, few people know that this tool itself loads only the system that is written for a specific smartphone or tablet model.

Bootloader: how to unlock and why is it needed?

As for the possibilities that unlocking the bootloader implies, the matter here is not limited to data recovery.

It is believed that in this case the user gets access to the system kernel, which is impossible by default. How to describe Bootloader in such a situation? What it is, it will become clear if you look at the lack of so-called superuser rights. It turns out that after the lock is released, they are not needed at all at any level. Otherwise, you often have to install special firmware and applications. If, to put it mildly, "clumsy", then the whole system can fly off.

Any manufacturer of mobile equipment provides for working with a component such as Bootloader. How to unlock it? This is usually done using special utilities installed on a PC when connected to a mobile device via a USB interface. Note that superuser rights are not required in this case.

For most devices, including, for example, Sony and HTC gadgets, the use of the Adb Run utility is implied, and for Sony you will have to additionally use special Sony Fastboot drivers, and even refer to the special Unlocker section on the official website. As you can see, the procedure, although feasible, is quite complicated.

Data recovery

On the other hand, in its standard mode of operation, restoring Bootloader after resetting to factory settings allows you to do it simply elementarily. It doesn't even require a hard reset.

It is enough just to reset the settings on the gadget itself, and after the reboot, the system will prompt you to choose an option: either use the new settings on the device, or restore settings, programs and files using a Google services account for this. In this case, you will have to enter a Gmail email address with a password, as well as connect to the Internet, for example, with an active Wi-Fi connection.

Installing another operating system

If we talk about the possibility of installing another OS, this issue is quite complicated, although we are solving it. The fact is that some manufacturers claim that after Android, another system will not be on the gadget. Pure advertising move, designed to advertise the installed system.

But the Chinese have already proved on their “left” HTC devices that both Android and Windows Phone get along quite simply on one device. At the same time, such models are delivered in most cases with an already unlocked Bootloader. What is it in this case? This is a tool that allows you not only to select the bootable OS, but also to install any other with changing the parameters at the system level.

In other words, the user can even do without any firmware or additional programs to optimize the work of the installed operating system. Furthermore! This does not even require specialized utilities like optimizers, which are so many today that the user himself does not understand what to choose from all this huge number of programs and applications.

What should be paid special attention to?

But when it comes to custom firmware, which has become quite popular with many owners of mobile devices, you need to be very careful with them. Of course, smart firmware or an OS update will not bring harm, rather, on the contrary, it will only improve the operation of the device, but when something unofficial is installed, and it has not yet been tested (like computer beta versions), expect trouble. Then certainly no loader will help.

By the way, few realize that such versions are capable of exerting too much load on the "iron" components, which, in turn, can lead to their complete inoperability. But changing the processor in the same smartphone is far from the easiest thing.

In addition, unlocking the bootloader in officially released branded gadgets implies an automatic loss of warranty and the possibility of free service. So you have to think a hundred times before performing such actions and operations.

Finally, it remains to add that the issue of installing another OS on an Android device is also, in general, quite controversial. Yes, of course, the system will rise, no matter what the manufacturer claims. But how it will work is another question, especially since most users usually install some kind of lightweight versions that have an unknown source of origin. But in vain. Here, as they say, you can break such firewood that you won’t end up with sin later. And the manufacturer himself, with such changes, according to current international standards, does not bear any responsibility for the correct operation of the mobile device. Therefore, the decision on expediency should be made by the owner of the gadget himself. But it's better not to joke with such things.

If you need to get root rights on a mobile gadget running Android (in the case when special utilities were not used for this), install your own firmware or third-party recovery, you need to unlock Bootloader. To do this, you can use official unlocking tools, but not third-party applications.

You can unlock Bootloader on most smartphones and tablets from various manufacturers. It may not work only on Chinese devices that
tied to the use of a single mobile operator.

It is worth noting that when you unlock the bootloader on the Android OS, all data from the gadget is eliminated. Therefore, if there is no synchronization with the “cloud” on the device or the data has not been transferred to the PC, it is recommended to do this before unlocking. In addition, there is an unlocking process that will not work correctly or fail, there is a possibility that the mobile gadget can no longer turn on. All this is the responsibility of the user.

In addition, there may be a possibility of voiding the warranty. It depends on the manufacturer. You also need to charge your smartphone before starting work. This is one of the important points.

Download Android SDK and USB driver to unlock Bootloader

First of all, you need to download the Android SDK from the official resource of the manufacturer. You need to visit http://developer.android.com/sdk/index.html and scroll to the Other download options section. Here you need to find the SDK Tools Only tab, from where you can download the required option.

When using Windows, you can download a ZIP archive, which can be unpacked to the desired directory on the PC disk. In addition, there is an installation wizard for Windows. In the Android SDK directory, you need to activate the SDK Manager. If you can't activate it and the window just appears and disappears, then you need to install Java from the developer's resource.

Once launched, you need to select the Android SDK Platform-tools, everything else is not required. If you are using Nexus, then you should highlight the Google USB driver, which is located at the bottom of the list. Then you need to click on the Install Packages button, and in a new window you should accept the license agreement, which will start downloading and installing the components. After the end of the process, you should exit the Android SDK Manager.

In addition, you need to download the USB driver for your specific mobile device model. In the case of Nexus, the download is done using the SDK Manager. When using Huawei, you need to download the HiSuite program, which includes this driver. HTC requires the HTC Sync Manager program, which includes a USB driver.

In the case of the Sony Xperia, to download the “firewood”, you need to go to the official resource of the smartphone manufacturer. For LG devices, you need to install the LG PC Suite application. For other models of mobile gadgets, you should look for a way to get drivers on the manufacturer's resources.

Enable USB Debugging

After that, you need to activate USB debugging on Android. To do this, you need to carry out several manipulations. First you need to go to the settings and find the item "About phone" in them. Then you need to make several clicks on the "Build Number" until a notification is displayed that the user has become a developer.

Next, you need to return to the main settings page and go to the "For Developers" section. Then you need to open the "Debugging" section and activate "USB Debugging". In addition, it is necessary to activate the "OEM Unlock" item in the manufacturer's parameters, if any.

Obtaining a key to unlock Bootloader

In most smartphones, except Nexus, in order to unlock the Bootloader, you need to get a code for it. To do this, use the official resources of the developer.

On these sites you can find a description of the unlocking process. In addition, there you can get an unlock code by gadget ID. It will come in handy in the future. To get a Device ID for Sony Xperia smartphones, you need to use IMEI on the official resource.

For Huawei mobile devices, the code can be found after registration and entering the necessary data on the official resource. In this case, you may need to enter the Product ID, which will be available after entering the code using the smartphone keypad code.

For HTC and LG smartphones, the procedure for finding out the key is performed differently. To find out the unlock key, you need to specify the Device ID. The first step is to turn off your mobile device. After that, you need to hold down the power and volume down buttons until the fastboot mode appears on the screen. On NTS smartphones, to select fastboot, you need to use the volume control and the power key.

Then you need to connect your smartphone to the PC. Next, you need to go to the Android SDK directory and select Platform-tools. After that, you need to hold down Shift and right-click and select "Launch command window".

After that, you need to enter the command:
On LG smartphones - fastboot oem device-id
On NTS smartphones - fastboot oem get_identifier_token and press Enter.

A digital key will appear on the screen, which is placed on several fields. This code is the Device ID, which must be registered on the manufacturer's resource in order to get the Bootloader opening key. In the case of LG, only a single unlock file is displayed.

Unlock Bootloader

If the fastboot mode is open, then you can continue to unlock the bootloader. If not, then you need to perform the manipulations described in the section above. After the fastboot screen appears, you need to perform several manipulations, which are different for each smartphone model.

If using Nexus 5x and 6p, you need to enter fastboot flashing unlock. For other Nexus models, fastboot oem unlock is required. Owners of NTS smartphones need to register fastboot oem unlock unlock_key unlock_code.bin. In this case, unlock_code.bin is a file received by mail. If LG mobile devices are used, then you need to enter fastboot flash unlock unlock.bin, where the latter is the sent file.

In Sony Xperia, you can see the command to open Bootloader on the manufacturer's resource, after choosing a model. In addition, to execute the command on the smartphone, you will need to confirm the unlocking of Bootloader. You must press "Yes" using the volume control and the power key.

After executing the command and waiting a bit (this time is necessary to delete files and write new ones, which will be displayed on the smartphone screen), the bootloader will be unlocked. Then, on the fastboot screen, using the volume and power buttons, you need to specify the item to restart and turn on the mobile gadget. This time the launch will take quite a long time. This may take up to 15 minutes, so be patient.
