We create Android firmware from improvised materials. How to reflash android at home Firmware creation

Experienced users are often looking for how to make the firmware of an Android device themselves. One of the key features of this operating system is that it is open source. It includes the core, user interface, libraries, and core applications, all of which are available for free.

What is custom firmware

Data-lazy-type="image" data-src="http://androidkak.ru/wp-content/uploads/2017/06/protech1-e1498230690613.jpg" alt="(!LANG: android tablet with tools" width="267" height="200"> !} Any user with the necessary technical skills can create their own operating systems using the Android source code and install them on smartphones. Thanks to such opportunities, many non-commercial projects have already been created, the participants of which are developing alternative distributions. Usually they are called "custom firmware", but "home-made firmware" can be considered a more accurate definition in this case.

Despite the fact that all the necessary materials are available to users, many people find that creating their own ROM is an impossible task. Success in this endeavor will depend on perseverance and how much time one is willing to devote to creating.

In order to install custom firmware on Android, you need to assess the scale of the upcoming task. If you have absolutely no coding experience, no command line skills (on Linux or Mac), and no idea what a Makefile is, then it's best to drop the idea.

Android is a complete operating system. It is quite complex and contains many different subsystems. Creating an OS is a useful thing, but it is also very complex. Any changes you want to make to the stock operating system will require careful consideration. It takes dedication and many hours of hard work to create an alternative distribution that is radically different from its predecessor. If the user has already had to deal with writing program code and he has an idea of ​​\u200b\u200bwhat a Makefile and compilers are, then creating your own version of the OS can be successful.

Theoretically, it would be possible to create custom firmware for any computing device capable of running a modern operating system. But it's best to limit yourself to creating a software environment for devices that are ideally combined with stock systems. The Nexus 5X smartphone will be used as an example.

What you need to create firmware

Data-lazy-type="image" data-src="http://androidkak.ru/wp-content/uploads/2017/06/linux-i-mac-e1498231546463.png" alt="(!LANG:linux and mac" width="300" height="171"> !} You will need access to a Linux or Mac computer to create the firmware. In both cases, the PC will be used frequently, so you need to be sure that the software environment you are using is working.

If you create your assembly using a Linux virtual machine, then with a high degree of probability it will not be able to recognize a mobile device and refuse to work with it. If you do not have a full-fledged Linux operating system at hand, then it is better to turn to a Mac computer.

In order to create your own firmware, you will need 130 GB of disk space and at least 8 GB of RAM. If you try to do this with 4 GB of RAM, then a lot of problems can arise. Similar difficulties can arise with 8 GB of RAM, but with the help of some tricks they can be overcome.

You need to be patient, because creating an Android build is a long process. It may take more than 24 hours to synchronize the source repository with the local machine. It will take a few more hours to create a complete build. Even after making minor changes, it can take 10-20 minutes for them to be accepted. Much will depend on the hardware, but do not hope that a powerful system will complete all processes in a few minutes.

The version of the operating system, called the Android Open Source Project, does not contain the usual Google services. As a result, apps like Google Play, YouTube, Gmail, and Chrome will be missing. Fortunately, there is already a way that can make these programs work on custom firmware.

The process of creating an assembly is that you need to download the Android Open Source Project and make changes to its source code. Google provides users with excellent documentation on how to create an AOSP. It is recommended that you read this manual carefully. A common mistake many users make is that they refuse to read the entire documentation, limiting themselves to only a few chapters that seem to be the most informative.

Process of creation

According to the instructions, you need to perform the following steps in turn:

1. Set up the build environment, including installing the necessary development tools and the Java Development Kit.
2. Extract the source code using the Repo tool.
3. Get your own binaries (some of the drivers are only released in binary form).
4. Select a target with the Lunch tool.
5. Run build using Make and Jack.
6. Install the firmware on the device using ADB and Fastboot.

Updating or installing firmware can eliminate many problems associated with the operation of an Android device. With prolonged use, the system memory of mobile gadgets becomes clogged with residual files () (“casts” of previously downloaded programs), malicious code () and other unnecessary data. All this leads to a decrease in the performance and speed of the processor and RAM. As a result, the smartphone (tablet) often freezes and reboots on its own. And if the factory reset () did not lead to a positive result, the user can only update the software himself. Consider how to reflash a phone running on the Android OS.

Types of firmware and how to install them

Android firmware at home is in many ways different from installing the rest of the software. This process is more time consuming and is associated with many risks. If you choose the wrong version of the software or violate the update process, there is a chance that your phone or tablet will turn into a useless "". However, having learned how much a flashing from professionals costs, many still decide to change the software version on their own.

For flashing Android, there is no single instruction that would fit all models of mobile devices. It all depends on the manufacturer of the device and what software is planned to be installed.

All Android firmware are divided into two types:

1. Official. They are supplied directly by smartphone manufacturers and are usually only suitable for a certain brand. Such programs are considered the most reliable, so they should be used whenever possible.
2. Unofficial (custom). Developed by users of Android devices and small firms. They are applied when Android is reinstalled on Chinese devices (for example, Lenovo, Meizu, Xiaomi, etc.).

When using custom software, there is a possibility of installing a low-quality update, as a result of which the gadget will start to slow down even more. Therefore, you need to download the executable file only after reading its description in detail and reading user reviews.

There are several ways to change the firmware on Android:

Preparing for self-flashing

Before reinstalling the software on an Android device, a number of preparatory measures must be taken:

• download a software update program on a PC (Odin, Kies or SP Flash Tool and find a high-quality usb cable (if the reinstallation is done using a computer);
• (if you plan to reinstall Android to an unofficial version);
• charge the battery of the gadget by 100%;

The functionality of the installed software largely depends on its version and assembly. So that the new firmware does not start to conflict with the hardware after some time, you need to find out the serial number of the mobile device:

We will consider a more detailed procedure for updating Android on a phone using the example of Samsung and Lenovo, although this instruction is also suitable for many other brands.

Smartphone firmware from Samsung

Software updates on Samsung devices are performed using the Kies program. This utility allows you not only to reflash a tablet or phone, but also to backup the old system, synchronize personal data with a PC, and much more.

Before upgrading the firmware to the latest software, you need to properly configure Kies. This is done as follows:

After setting up Kies, create a backup of the software available on your smartphone. This will restore the system to working capacity in case of unsuccessful firmware. To backup Android via PC, in the initial window of the application, select "Backup", check the items that you want to save, and start the procedure by clicking the appropriate button.

After creating a backup, feel free to reflash your phone or tablet through a computer. To do this, open the "Tools" section in Kies and activate the item marked in the figure, thereby starting the update process.

While the device is being flashed, in no case disconnect it from the PC and do not perform other actions that may lead to a disconnection.

After flashing the Android phone through a computer, check the performance of all its functions. If nothing fails, then the software update was successful.

Replacing the firmware on a Lenovo tablet via a PC

Before flashing a Lenovo tablet, you need to understand that there is no software developed specifically for this brand. Therefore, one has to be content with universal developments. One such application is the SP Flash Tool. Consider how to update the software on Lenovo using this utility:

After you managed to update the firmware, check the performance of all tablet functions.

The firmware on any modern smartphone, including devices on the Android platform, allows you to modify literally every element to your own taste. And although ordinary users usually use ready-made options, you can create the firmware yourself. This will require a number of special tools, which we will discuss in this manual.

Before moving on to the basics, you need to consider: even if you strictly adhere to the restrictions and recommendations from our article, your device may become inoperative. This is due to many factors, from minor bugs to lack of compatibility. Therefore, by any available means, check compatibility to keep the device intact.

Step 1: Install Recovery

In one of the instructions on our website, the process of installing custom recovery, which is necessary for flashing an Android device, was considered. This step is mandatory and must be completed in advance before working with the firmware itself. At the same time, remember that different smartphones use their own version, but this will not affect the further process in any way, with the exception of some differences in the interface.

Step 2: Firmware Selection

In addition to adding a bootloader with the ability to save access to files on the device, you need to find the firmware that is compatible with your device. In this matter, it is difficult to give any specific advice, since there are a huge number of smartphones and an equally large range of firmware. The easiest way to find a suitable option is to visit the section Android on the Russian-language forum w3bsit3-dns.com or on the English-language resource XDA Developers.

Having found a section with firmware for your device, preference should be given to clean versions that have not been modified by the author. This is necessary in order to change the firmware from scratch without replacing or cutting out other elements. Download the ZIP archive to your computer, where further changes will be made.

Step 3: Preparing the system on the PC

The dedicated PC software discussed in the next section is equally compatible with Windows, Linux, and MacOS. The most convenient method is to use Linux-based systems, while Windows will require a number of additional steps and programs. Due to the much greater prevalence of the second option, we will pay attention to the Windows OS.

1. Visit the official Oracle website and download the JDK software according to the bitness of your operating system.

   Click on the downloaded EXE file and install the program.



2. Following the JDK, you need to download and install Cygwin. To do this, visit the topic on the w3bsit3-dns.com forum at the link below.
3. Open the downloaded archive using any convenient archiver and extract the existing files.



4. Among the received files, double click on setup to start the installation.



5. At the stage Choose A Download Source choose an option "Install from Local Directory" and press "Further".



6. In line root directory leave the path unchanged using the button "Further".



7. Next you need to change Local Package Directory, pointing to the Cygwin folder that you extracted from the archive earlier. For example, in our situation, it is on the desktop, and therefore the path looks like the one shown in the screenshot.



8. The last step is to select the components in the window Select Packages, which will appear almost immediately after the installation starts. Click on a line All so that a label appears next to each item Install.

   

   Further steps to install Cygwin are performed automatically.

   

   If you wish, you can create a shortcut on the desktop for more convenient launch of the program.



9. Run the program using the created icon. On Windows above seven, use "Run as administrator".

   

   Wait for the directory and file creation to complete in the console, then close Cygwin.

Step 4Using Android Kitchen

The Android Kitchen program, also known as the "kitchen", is the most convenient tool for creating custom ROMs. You can download the archive from the official page on Github at the link below. It is best to take the latest released version of the software.

Close the "kitchen" and move on to the next step.

Step 5: Build Firmware

The most important and most time-consuming part is the assembly of the firmware, as this process must be done with care to eliminate the possibility of errors. This procedure will not be a problem if you have experience. For the same reason, we will not focus on the assembly stage, mentioning only a few points.

After completing the editing procedure, you can start flashing the device.

Step 6: Install Firmware

As in the case of installing recovery, the procedure for installing custom firmware, regardless of the option to obtain it, was described by us in a separate article on the site. You can get to know it by following the link below. Please note that different types of firmware can be installed in different ways.

Conclusion

We hope our article helped you figure out the procedure for creating your own firmware for an Android device. It is important to bear in mind that without experience and understanding, it will not be possible to achieve the desired result, even if you pay attention to specific examples. This is due to a lot of differences in the case of different firmware, versions of Android and smartphones.

Let's start with what phone firmware means. This concept refers to the operating system of a mobile device. A software package consists of an operating system kernel and drivers, also known as hardware. They are responsible for the functioning of the elements of the device. The phrase “flash the phone” is understood as the process of installing software. Installing the software can be difficult for novice users. In some cases, a software package is created individually for a specific instrument model. Flashing may fail due to lack of knowledge about the algorithms of the procedure and lack of information.

The platform is very popular. It is open for free access, so it is used by many manufacturers of mobile gadgets. There are several reasons why you need to reflash Android:

• Work failures. Not a single, even the most expensive device is immune from errors. The new installation of the platform will eliminate any failures that are not related to breakdowns of the internal and external elements of the device itself.
• Upgrade. Platform developers often release new versions of the software. The system receives new features and interface updates. The update will allow better use of the hardware capabilities of the device.
• Inconvenient software from the gadget manufacturer. Some brands install their own developments in the units. They may be uncomfortable. Pure Android firmware is not overflowing with features and marketing gimmicks. The user is guaranteed continuity, performance and automatic application updates.

Preparatory activities

Reinstallation of the platform requires care and strict adherence to technology. If a mistake is made, you will have at your disposal a useless piece of chips in a plastic case.

Before the firmware you need to prepare. Be sure to charge your gadget up to 100%.

Before flashing your phone, you need to take into account the current version of Android, the amount of RAM (maybe a newer version of Android will slow down if the RAM is low), and the model of the phone. In the settings menu, you need to find the full name of the device and the modification of the current software. It is advisable to write them down to the last character.

Before starting the procedure, you need to perform Backup. This term refers to backing up data so that it can be rolled back to its original state if something went wrong during the firmware. It's easy to do.

The device must be turned off before formatting and backing up. After reformatting, boot files will start downloading to the SD card. When the download is complete, a message will appear on the screen.

Services that you can use before flashing Android through a computer without involving a specialist:

• super backup. The service is convenient and fast. Using the utility, you can back up and restore data. The service offers to buy a premium version. When using it, ads are disabled. You can also use the free version.
• Helium App Sync Backup. This application is also available in paid and free versions. Basic options such as SMS backup and call log backup are free. If you want to get your hands on the cloud, so that it is more convenient to reinstall Android and get rid of advertising banners, you will have to fork out.
• ultimate backup. There are paid features, such as file recovery from the cloud. The free version has a backup option and a task killer that allows you to forcefully complete the flashing process. A useful bonus is clearing the aggregate from the cache.

There are other applications that help you make a backup. We have reviewed the most convenient.

How to reinstall Android yourself

Before reinstalling, you need to download the firmware. It is better to do this from the official website of the device. Otherwise, after reinstallation, it may stop working. The firmware is selected depending on the model of the mobile device. On the website of the manufacturer of the device, they can request developer rights. To do this, you need to use any application from Google Play. After you need to download CWN-recovery for your mobile device model. The downloaded archive must be placed on the SD card. To place the downloaded firmware software for Android, you should not use the built-in memory of the device. In this case, it can hardly be called reliable storage, since all data from the phone will be erased.

To reflash the device using Recovery, you need to turn off the device. To do this, simultaneously press the Power (on / off) + Volume Up (volume increase) buttons. Some models may have a different key combination. Before flashing your smartphone, you need to wait until the device vibrates. A window will appear. In it, you need to select the Recovery Mode key. Next, specify apply update from external storage. The installation process will begin. After it is completed, the device must be rebooted.

To flash a gadget, it is better to use a PC or laptop. Windows, starting from the seventh version, does not require drivers to work with the device. Or she offers to find them on the Internet. Before flashing Android from a computer, you need to fully charge the device. Next, you need to do the following manipulations:

1. Transfer the Software Update Tool and drivers to your hard drive.
2. Turn off the device.
3. Press Power (on / off) + Volume Up (volume increase). The device should vibrate for a while.
4. After Fastboot USB appears on the screen, connect the device to the PC.
5. Open the application to install the software.
6. Specify the location of the saved software.
7. Specify the type of OS.
8. Click Erase user data.
9. Click "Start".

After these manipulations, the firmware on Android will be downloaded to the device. This will take some time. The new system will be installed. Then you need to reboot the device. It will take longer than usual to turn it on for the first time. Don't worry about this.

When working with a PC, there are several important nuances to consider. The PC on which the operation will take place must have at least a dual-core processor. You should choose devices with the latest versions of Windows or Linux.

The software can be installed without a PC - using one SD card. Before flashing Android in this way, charge the battery to 100%. Do not turn off the power supply while downloading. Launch ROM Manager. Click on the "Install ROM from SD card" button. Specify the location of the archive with the software. Click OK. Wait for the installation to finish.

Another option for installing software in a mobile gadget is to update it to the next version. First of all, the user needs to find out what version of the software is in his device. To do this, you need to look in the “About phone” section in the settings. Usually you get a system notification that updates are available. However, the notification does not always arrive on time. In addition, there is a possibility that you accidentally erase it.

Before you update Android to 6 or to another available version, you need to confirm the action. The download will start automatically in the background.

To update the software, find the “System Update” button in the system settings, click “OK”. The software will download in the background. After installing all the components, you need to restart the machine. In some cases, it is not possible to download a new version of the OS. This is due to the fact that under this model they are not available. Or the latest version is already installed. Usually, manufacturers stop releasing fresh software for units older than 3 years.

What are the programs for flashing Android from a computer

The most successful services:

• ROM manager. This utility is installed to boot the OS from an SD card without using a computer.
• SP FLASH TOOL. The service is designed to work with a PC. Requires device to be connected via USB cable. The main advantage of this utility is its versatility. It is suitable for many models of devices. The service has an intuitive interface that even a novice user will understand.

There are services developed for a specific manufacturer. So, for Samsung devices, the ODIN utility has been developed. This is a service of own production of a well-known South Korean corporation. It has a simple operation principle and a clear interface. Before flashing Samsung, be sure to download ODIN.

What to do if the device does not turn on?

You can reinstall the software if the bootloader is not damaged. To check this, press the On/Off button. If an image of a robot or some kind of sign appears, for example, “!”, it can be assumed that a software malfunction has occurred. After that, connect the device with a USB cable to the PC. Press the On/Off button and VolumePlus. The PC will find the device. In 95% of cases, you can successfully install the OS using one of the above programs for flashing your phone through a computer.

The device may not start after installing the software. Do not say goodbye to the unit. It can be revived. First of all, try restarting your device again. If the gadget does not start again, then you can try to return it to its original state using previously downloaded backup data or try reinstalling the software. Then the procedure will have to be repeated from the beginning.

We looked at different services and ways to flash mobile devices. Now you know how to reflash Android yourself through a PC and without it.

How to reflash an android phone through a computer at home - this is exactly what this article is about! When nothing works on your Android phone or everything slows down and lags, while the usual tips (clearing the cache or freeing up the phone’s memory) do not help, it’s time to resort to drastic measures, such as flashing Android. Flashing an anodroid phone is not a difficult task, you can flash the phone at home, by yourself, today we will tell you in detail how to do it!

• The core "Android" itself;
• Drivers that ensure the coordinated functioning of the components of a particular device model, that is, hardware.

The verb “Flash” the device refers to the procedure for installing the platform. However, the process of installing an operating system for a computer and for a mobile gadget on the Android platform is significantly different. The reasons for this are the huge variety of implementations of this most common OS in mobile devices. A lot of software is created individually for certain models of smartphones and tablets. Therefore, often for inexperienced users, installing a new firmware fails due to lack of information and the lack of correct action algorithms before their eyes.

The following guide will help you reflash Android at home, as well as introduce you to the possible risks of the procedure and ways to minimize them.

Why you need to reflash an android phone?

Gadgets are made and programmed by people, so no device is completely immune from errors. In the event of a failure in a smartphone (tablet) on Android, a cardinal method of getting rid of the problem is flashing.

Arguments "For" reinstalling the OS

Thanks to the openness of this operating system, manufacturers are free to improve and customize it to fit their gadget models. Many of their advanced software have already won the love and trust of users. In this regard, often the owners of smartphones and tablets take risks and decide to flash their electronic friend. This is also facilitated by some developers who eventually stop releasing updates for their gadgets. Users from various sources of information learn about new software modifications that can make optimal use of the hardware capabilities of the device and, of course, wonder how to reflash Android.

Even very well-known companies producing smartphones and tablets often sin by installing their own software in them, which for obvious reasons is not suitable for most users. In addition to the unsuccessful external design of the shell, these proprietary software significantly slows down the functioning of the device. At the same time, pure Android, not stuffed with unnecessary marketing chips from the developer, often impresses with its high performance and stability. Therefore, the answer to the question posed is the installation of custom software, in which there is no pre-installed "trash" from the manufacturer.

Arguments "Against" OS reinstallation

With a lack of experience or insufficient care, there is a big risk of getting a non-working and useless piece of chips and plastic after the procedure, or as experts used to call this failed device - “Brick”.

In the case of firmware firmware taken from unofficial sources, the device warranty will be void.

Not all drivers included in the software package from a third-party developer work correctly with gadget components. It happens that after flashing the GPS module refuses to search for satellites, and the camera takes low-quality frames. Also, not optimally selected software can cause rapid battery discharge.

How to flash an Android phone yourself and what is needed for this?

The success of any event depends on how carefully the preliminary preparation was carried out.

Preparatory activities include the following main points:

• Be sure to fully charge the device before starting the procedure;
• Through the gadget's settings menu, find out the name of the device and the modification of the current software (it is recommended to write them down to the last character and sign, otherwise, if the firmware is not of the appropriate assembly, you can get a “brick” as a result);

Each user must independently decide which version of the software to prefer:

a) official;
b) a third party.

Having completed all three points of the preliminary measures and, most importantly, having accurately determined the modification of the software, you should proceed directly to the installation procedure.

There are the following ways to do this:

• Update (When an updated version of the software has already been released for the device, the “Auto-update” is a convenient method for all users. In order to find out if a new firmware version is available, open the “About phone” section through the settings and go to the “System Update” subsection).
• Manual installation (For models from different manufacturers, different firmware methods are used using different software, which are called “Flashers”. For example, for gadgets from Samsung, the Odin program is used, for Nexus, Sony and HTC - "Fastboot", "Lenovo" - "Flash Tool", "LG" - "KDZ Updater", etc.).

The list of steps in the flashing procedure using the ROM Manager program:

• Get root rights to the android gadget;
• Install the ROM Manager utility;
• Create a copy of the current OS;
• Find and save the appropriate firmware;
• Install it;
• Test the work of the new software and, if you are not satisfied with the results, return to the former version using the created copy in paragraph "3".

You can find and install the "ROM Manager" utility from the Google play store. Then, by opening the main application window and clicking on the top line, you can install "ClockWorkMod" (CWM), and using the second line - "Load Recovery Mode".

In order to save a copy of the OS, you will need to install "CWM".

Important digression: During the installation of "CWM", the gadget should not be connected to the PC.

By clicking on "Install CWM" you will need to specify the exact name of the gadget and wait for the installation procedure to complete.

Where to get firmware for Android?

They are available for download on the official resources of the smartphone and tablet developers themselves. If the user has sufficient experience, then by the name of the model, he can find many versions of the software on third-party sites, from which the appropriate one is selected and its archive file is saved in the computer's memory. Then you can write it to a memory card without unzipping the file.

In the case of using the "ROM Manager Premium" utility, the user can click on the line "Download Firmware". After that, the application will display a list of software suitable for the device. This useful program eliminates the loss of time searching for software in the Internet resources of third-party developers, of which there are currently a huge number.

Why do we need non-official (custom) firmware for Android?

Non-official software is developed to ensure faster operation of the device, and some useful functions and good design can be added to it.

Custom firmware sometimes continues to be improved by developers even when an outdated gadget is discontinued. Therefore, the user receives a device with updated software that optimally meets modern requirements.

For some users, it happens that the decisive criterion for deciding in favor of installing a third-party product is battery savings and a more attractive interface.

By installing non-official software, you can immediately provide yourself with root rights, which means you can increase your security by installing a powerful firewall. The owner of the gadget, at his discretion, will be able to install any fonts he likes, as well as increase the speed of the GPS module, etc.

You can get rid of unused system utilities that not only take up memory space, but also consume mobile traffic, this is especially true if the user does not have access to an unlimited Wi-Fi network.

How to flash an Android phone through a computer at home?

If the owner of the device is interested in the question of how to flash an Android phone through a computer, then the following will be needed:

1. Install drivers on the PC to work with the device;
2. Download the firmware corresponding to the gadget model;
3. Create a backup copy of the current OS in the device;
4. Install the firmware application (flasher).

The essence of the actions is the same for various models of devices. Below is an example of working with the Odin flasher from Samsung:

• Connect your device to PC in download mode. To do this, turn off the gadget and simultaneously press the keys: "Home", "On / Off." and "Sound up".
• Next, "Odin" will see the device;
• Then in the column "AP" indicate the location of the downloaded software;
• Set marks in the columns "F. Reset Time" and "Auto reboot";
• Click "Start";
• Wait for the process to complete.

The sequence of actions consists of the following steps:

1. Launch "ROM Manager" and click "Install ROM from SD card";
2. Specify the location of the distribution kit copied to the map with the OS;
3. In the menu that appears, check the boxes of the items of interest to the user and click on “Ok”;
4. Wait for the installation procedure to complete.

How to reflash Android via Recovery yourself?

To install the software using Recovery, you must first save the firmware file on the device card. Next, you will need to perform the following steps:

• Turn off the device;
• Simultaneously press the keys: "On / Off." and "Increase the sound level" (on some models, the combination of buttons may be different);
• In the window that appears, specify "Recovery Mode" (the transition between the columns is done with the buttons to increase and decrease the sound level);
• Next, specify "apply update from external storage" and click the "On / Off" button;
• Wait until the process completes.

To the question of how to flash an Android tablet, there are already detailed answers in the above paragraphs of this guide. All actions in gadgets on Android will be identical. For example, consider the procedure using a PC in relation to a model from the popular Lenovo company.

You need to follow these steps:

1. Fully charge the tablet;
2. Install the "Software Update Tool" application and drivers. Save an archive with a suitable firmware distribution kit in memory;
3. Disable mobile gadget;
4. Simultaneously press the keys: "On / Off." and “Volume down” (the device should vibrate);
5. After displaying "Fastboot USB" on the display, connect the gadget to the computer;
6. Open the installed application and specify the location of the saved distribution;
7. Next, in the program menu, specify the type of software;
8. Click "Erase user data";
9. Click "Start" and wait until the process is completed.

Programs for flashing Android

Many applications have already been developed for this purpose. Here are the most successful utilities that have proven their reliability and have earned positive user reviews.

This utility is installed directly into the device itself. The firmware is installed from the gadget's CD-card.

A universal utility that is suitable for almost all devices on the Android platform. Installation is done only through a computer, so you will definitely need a USB cable. Intuitive interface allows even novice users to cope with the difficult task of reinstalling the system

fastboot

This is one of the most difficult applications for beginners. The actions in it are a bit confusing. The installation procedure is carried out through the console of the Windows operating system.

How to flash a phone if it does not turn on?

It will be possible to successfully solve the question posed only if the integrity of the bootloader is not violated. In order to find out this, you can hold down the "On / Off" button. If a response from the device appears in the form of a robot display or some icon, for example, “!”, then we can conclude that the OS has failed. You can also try to connect the device to the PC via the USB cable and press the following keys on the device: "On / Off." and "Volume". When after that the PC finds the gadget, then resuscitation will not be difficult and in 95% of cases it will be successful. Then you can use one of the above methods and install new software. Not infrequently, incorrectly executed firmware violates the recovery partition, after which only the installation of the correct OS modification will allow the gadget to be restored.

The algorithm of actions is as follows:

1. Install the firmware utility on the PC;
2. Download and save the firmware file;
