Android does not load how to restore. The solution to the problem is flashing the android phone through the computer if it does not turn on. Troubleshooting. or freezes. Android firmware through a computer if it does not turn on How to make a phone if the firmware has crashed

Read in this article how to flash Android through a computer. How to flash a smartphone, what is Android phone firmware, why is it needed - common questions from novice users who first encountered problems on a device controlled by a "green man".

As a rule, flashing comes to the aid of users whose gadgets refuse to work or are unstable. With the widespread adoption of Android devices from China that cannot boast long-term support from the manufacturer, third-party firmware has become popular, allowing you to upgrade to the latest version of the OS. So that you do not get confused, let's go in order.

What is Android flashing, why is it needed

The term "flashing" itself has become widely used with the filling of the market with smartphones running the Android OS. The new system opened up a bunch of possibilities for the user, including openness, which allowed everyone to change Android as they wish.

You can reflash not only a smartphone, but also a regular mobile phone - they also work on an OS, albeit a simpler one.

What does the term “flash Android” hide behind? Any modern smartphone, as we have already indicated, runs on an operating system (a set of software tools that ensure the correct operation of the hardware), which is characterized by errors, glitches and other problems. The OS of the phone can also crash, just like Windows on your computer. And in this case, the way out is to reinstall the system or flash it.

However, flashing can not only fix errors. Installing a new firmware brings updates that ensure the stable operation of the smartphone, and often make the process of interaction between a person and a device more understandable and enjoyable.

Firmware can be divided into two classes:

Official (stock). Firmware released by the manufacturer of the Android device. Since they are developed specifically for a specific model, the likelihood of errors during flashing or during operation is minimized.
Third party (custom, unofficial). Firmware developed by ordinary users or small groups. Android is taken as the basis (the OS is open, so everyone can work with its program code), into which improvements are subsequently made. Third-party firmware does not guarantee perfect performance on your device, may contain various errors unnoticed by the developer.

Unofficial firmware, as a rule, is developed for those that have not acquired system localization into other languages or do not receive updates. Developers are especially interested in inexpensive devices with good hardware, which are popular among users.

How to flash a smartphone on Android?

There are some pretty simple ways.

OTA-update. In fact, this is not firmware. You simply update the OS version using the device's regular means. The process is very simple, besides, we have already talked about it in detail,. The only thing worth noting is that not every smartphone receives updates “over the air”, and owners of models from little-known companies may never see them at all.
Flashing with a smartphone. Using only a smartphone and a couple of applications, you can easily install a new firmware that you downloaded from an official or unofficial resource. The method is quite simple, but you should first familiarize yourself with what we also wrote about.
flashingAndroidthrough a computer. A way to flash Android, which we will talk about today. It is, let's say right away, somewhat more complicated than those presented above. But it offers much more options.

Before flashing

Let's not rush. To begin with, you should warn against possible undesirable consequences and some of the nuances that may arise when flashing Android through a computer.

Data backup

The very first thing you should do is back up your important data. Necessarily! During the flashing process, absolutely all files from the device memory will be deleted. Therefore, save the necessary information in advance to a personal computer or to cloud storage so that you can quickly restore everything later.

Backup copy of the installed firmware

It will not be superfluous to make a backup of the system itself, so that in case of problems during the flashing, there is something to recover from. To create a backup copy of the OS, the simplest tool is, which we have already written about.

Quality wire, fully charged battery

Quite often, the cause of errors in the process of flashing Android through a computer is a low-quality USB cable bought for a few cents. Often, a smartphone is not detected by a PC at all due to a bad wire. Therefore, we recommend buying a high-quality cable in the store, but more expensive.

Be sure to charge your smartphone battery to 100%. Firmware can take a long time, and power from the USB port is intermittent.

Possible problems

Remember! You do flashing at your own peril and risk. This process, although not so complicated, is often accompanied by errors that can lead to the inoperability of individual smartphone functions or to corruption (complete failure). Although most of the problems that arise can be corrected, some cannot be treated even in service centers.

Be careful when flashing. It will be very useful to first familiarize yourself with the forums where users share what can destroy your particular device. Feel free to clarify the nuances that you do not understand.

The market is just filled with a wide variety of Android devices, so it is difficult to predict what errors may occur in your particular case. The reasons may be incorrect user actions, "clumsy" third-party firmware, problems with the cable, drivers, and so on.

By flashing your device, you lose the manufacturer's warranty.

If you are not confident in your abilities, then it is better to contact the service center. Specialists with a guarantee will reflash your device, and you do not have to read the article further.

How to flash an Android device through a computer

So, readers who were afraid of possible problems were weeded out, and we are moving from theory to practice.

USB debugging mode and required drivers

To get started, pick up a smartphone or other Android device to activate the USB Debugging mode. This is done so that the computer can make changes to the device connected via USB. So the instruction:

first of all, we will acquire developer rights so that a special menu in the settings becomes available to us;

To gain access to the developer menu, you need to make multiple clicks on the "OS version" item. It is located in the “About phone” section (the very last item in the device settings).

after the rights are obtained, go to the "Developer Menu", which will appear in the settings;
here we find the item "Debugging via USB", make the switch opposite it active.

The smartphone can be put aside. Let's move on to the drivers that are useful for flashing Android through a computer.

Drivers for each device are different. You can download them on the official website of the manufacturer or on one of the forums.

To install drivers:

connect the device to the computer;
go to the "Device Manager" (use the search or find the section in the "Control Panel";
find the item with the name of your device (the smartphone or tablet may not be detected by the system, in this case a line with an unknown device will appear, next to which is a yellow triangle);
right-click to open the context menu for this device;
select "Update driver" from the list;
click on the item "Search for drivers on this computer";
then click "Select a driver from the list of already installed";
by clicking on the "Install from disk" button, specify the path to the downloaded drivers;
restart your PC and smartphone for the changes to take effect.

Often, a smartphone driver alone is not enough. For some devices, you have to install additional USB port drivers so that the PC can detect them. In addition, numerous devices require the installation of the ADB tool.

Android Debug Bridge (Android debug bridge) is a console application that is used to manage Android devices through a personal computer.

Returning to the fact that Android devices are countless, for individual devices you have to download a whole bunch of special software. The list of software can be found on the official websites of manufacturers or on thematic forums dedicated to flashing your particular gadget.

Programs for flashing Android through a computer

We are approaching the choice of software, which we will use directly to install the firmware on a smartphone or tablet. For these purposes, a whole bunch of programs are presented, but all of them can be divided into two broad groups:

Firmware for specific models. Proprietary programs produced by companies exclusively for their devices. Almost every major manufacturer offers a free version for download. Programs for flashing certain models provide a quick and error-free installation of a new firmware, in addition, they have additional tools that will allow you to backup the system and roll back in case of critical errors. The following companies provided similar software: Samsung (Odin); Lenovo (Flash Tool); HTC (Fastboot); LG (KDZ Updater); Sony (Flashboot); Nexus (Fastboot).
Universal software for firmware. Programs that can be used to flash any android devices. There are also a lot of them, but the possibilities are about the same. The most popular tools are QFIL and SP Flash Tool: the first is for flashing devices with Qualcomm Snapdragon processors, the second is Mediatek.

Unlock Bootloader

So many smartphones, so that the user cannot freely make changes to the system, are presented with a locked Bootloader (bootloader). Bootloader is a special program that is responsible for accessing the kernel. From which we conclude that while it is blocked, we will not be able to flash anything.

Bootloader is unlocked using special software provided by the manufacturer with the necessary instructions. As a rule, it all comes down to installing a special program (for example, HTC has Bootloader Unlock), activating USB debugging mode on the smartphone (how to do this is described a little higher) and pressing just one button - “Unlock” (Unlock).

Choosing the firmware

When all the drivers are installed, the bootloader is unlocked and the program for flashing Android via a computer is downloaded, you can proceed to select the firmware. Here it all depends on your device: there may be darkness or no firmware at all. There are several types of firmware:

Official. Presented by the manufacturer without any changes.
Unofficial on the basis of the official. Firmware that has been finalized by third-party developers, but with a minimum of changes (language support added, bugs fixed, and so on).
Unofficial. There are also redesigned firmware, which are simply crammed with a variety of features. They are developed based on Android, ready to offer a bunch of new features, but often contain bugs. The most famous of them: CyanogenMod, Lineage OS, OxygenOS and others.

You can download firmware on official websites, forums and other resources.

As we have already noted, the principle of operation of all programs for flashing is approximately the same. We will talk in more detail about the firmware using the SP Flash Tool.

We remind you once again that the SP Flash Tool is a tool for flashing only devices with processors from Mediatek. You can find out which chip your smartphone has on the official website of the manufacturer or using special applications (AIDA64 and similar).

So, smartphone is not connected yet, we work only with the program on the PC:

unpack the firmware if it is in the archive (it is better to do this in the root of drive C);
run the SP Flash Tool program (recommended on behalf of the administrator);
specify the path to the scatter file by clicking on the "Scatter Loading" button, which is located in the right part of the window (the file is located in the folder with the firmware, the name ends like this - emmc.txt);
necessarily uncheck the Preloader item (if your device runs on an MT6575 or MT6577 processor, then uncheck the dsp_bl item as well);
select Download Only from the list;
press the Download button, next to which there is a blue or green arrow icon (depending on the version of the program);
just now we connect the Android device to the computer without using any adapters - only one wire;

The device must be turned off.

the program will start searching for a smartphone (if it does not find it, remove and insert the battery; if the device has a non-removable battery, then disconnect and reconnect the cable);
after the device is detected, the flashing process will begin, which may take a long time;

Do not disconnect the device from the computer!

we are waiting for the appearance of a window with a green circle;
only now we disconnect the device from the computer and try to turn it on.

The first launch process can take quite a long time (about 10 minutes), just wait.

Approximately according to the same scheme, devices are flashed with other programs. However, do not neglect the instructions for use. Study them thoroughly, only then proceed to the firmware.

Conclusion

Flashing an Android device through a personal computer is a rather complicated task, with a lot of nuances, but even beginners can do it. The main thing in this matter is not to lose sight of every moment, so that later you don’t look on the Web for how to reanimate a brick. Take your time, carefully study the instructions specifically for your smartphone, since there are a lot of them on the Internet, and figure out the sequence of actions. Well, we can only wish you good luck with the flashing!

Articles and Lifehacks

Many phone owners are trying to improve their devices, and therefore they reflash them even when it is not necessary.

But what to do if the phone does not turn on after the firmware, is the firmware to blame or the mobile device itself is out of order?

Actions after flashing the phone

To bring your phone back to life:

Remove the SIM card and memory card from the device.
Connect your phone to PC with USB cable.
Go to Device Manager.
Hold the power button of the mobile phone for a few seconds, then release it and hold it again for 15 seconds.
The system should detect 2 connected devices.
If there are no exclamation marks next to the name of the devices in the Device Manager, then you can proceed further. If the sign is there, then you will have to look for new drivers for your cell phone.
Download the Phoenix program on the PC, connect the phone, launch the application, while selecting No connection. After that, go to the File menu, select your phone model.
After that, you will need to find Firmware Update, select Product Code and choose the required firmware.
Check the box next to Dead Phone USB flashing.
Click on Refurbish, wait for Output to appear. Press the power button on the phone, then wait for the end of the firmware. The mobile phone should turn on by itself.

What you need to know about firmware

If you want to experiment with your phone, namely, to reflash it, then it is better to think several times before doing this. If you are far from electronics, then it is better to leave these actions for professionals.
In some cases, the mobile phone after the firmware refuses to turn on due to a dead battery. Therefore, before each firmware, check that the phone has enough charge.
If during the firmware you dropped the device, then it is best to take it to a service center, as you could damage important parts of the device. Try to treat your mobile phone with care so that it pleases you for a long time.

Why flash Android? Because of the desire to expand the functionality, see what your gadget might look like in a new “wrapper”, restore the phone when there is no way to roll back, etc. But regardless of the reason, this is how it is done.

How to install firmware on Android from a computer?

First you need to download it. It is best to download the official one from the mobile device manufacturer's website. It is worth noting that the software is selected directly for a specific phone model, otherwise it may not “become”, which may cause additional problems.

Need to know

Before flashing a mobile device, you need to remember and follow a few rules:

It is necessary that the battery charge of the phone be at least 80%, and preferably 100%.
Install drivers on your computer for your device.
It is highly undesirable if the Android firmware through the PC breaks due to a power outage. Therefore, it is best to use a laptop or with an uninterruptible power supply in this matter.
To protect your device from low-quality OS, you need to make a backup copy of the current software and data.
It is highly undesirable to use the USB 3.0 port when flashing (USB 3.0 port is blue, 2.0 is white).
Once again, before downloading the firmware, you must carefully read it. You should also avoid suspicious sites.
It is best to use the original USB cable that came with the device.
Usually, after flashing, the device's power button needs to be held for 15-20 seconds, so do not panic if it turns on for a long time. Then it will turn on as before.

fastboot

Using Fastboot, Android tablet firmware is available through a computer. Download the Fastboot utility, unpack it to the root of the system drive (most often it is drive C). The result is a folder with the path to it C:\Android. There are 2 more folders: Tools and Drivers. The first contains the necessary programs, the second contains the drivers. Open the Drivers folder and install the necessary drivers. Next, transfer the downloaded firmware in a zip archive to the Tools folder. Now we connect the gadget to the computer via USB.

Open a command prompt (or cmd) and enter the command without quotes "cd C:\Android\Tools". Having moved to the directory of this folder, we enter fastboot devices.

In this case, the device code should appear. If the code does not appear, then you need to unlock the bootloader.

Bootloader gives OS information about the state of the memory card, RAM, kernel and is responsible for loading the OS. And if it is not unlocked, then the flashing will fail. It is worth noting that when the bootloader is unlocked, the device loses its warranty. However, it is quite easy to block it back if the need arises. You need to pay attention to the fact that unlocking will erase all the contents of the device and the memory card, so it would be best to make data from the internal memory and SD card before doing this.

Unlock bootloader

To unlock the bootloader (and flashing the Android tablet through the computer has become possible), you need to follow these steps:

Turn off your mobile device.
We connect it to the PC and hold down the power button and both volumes at the same time.
On the computer, open the command line (or cmd), where we enter without quotes "cd C:\Android\Tools".
Enter the fastboot oem unlock command.
We check again with the fastboot devices command.
If instead of the gadget code the message waiting for device appears, you should check for drivers and change the USB cable.

If the device was recognized, enter the command: fastboot update filename.zip. Reboot after flashing.

flash tool

Before installing the firmware on Android from a computer using the Flashtool utility, you need to download the operating system in ftf format. After downloading and installing the program. The downloaded file for flashing is placed in the Firmwares folder, which is located in the program directory. We start the utility.

Click on the button with the lightning icon in the upper left corner, leave a dot on Flashmode.

Now you need an operating system file from the list for the gadget, on the right there should be ticks for Wipe User Data and Wipe Cache. We wait a bit, after which a window with instructions for connecting the phone will appear. We connect it to the computer and simultaneously hold down the power button and the volume down (camera, menu - the key combination may be different for different phones, so you need to clarify it for a specific model). As soon as the program gains access, the automatic "Android" will be installed quite quickly, within a few minutes.

After the process is completed, turn on the gadget and go through the initial setup.

This method of installing software is one of the best, since you can install firmware on Android from a computer using Flashtool when the phone is turned off, which does not have Recovery mode.

With the help of specialized programs

Many developers of mobile devices have developed special service utilities. One of these utilities is software update for Fly smartphones. With its help, it became possible to update the current OS and firmware "Android" through the computer of the Fly-smartphone.

Download it, install it. Once installed, the utility will offer to connect the device to the PC. It is worth noting that it must be enabled. If it is disabled, the utility itself will help to do this. After that, click "Install Driver".

We connect the smartphone, run the utility. Click "Check for update" and select the model from the list (if you haven't decided yourself). Next, a window with information about the software will appear, where we click "Start Download" and follow the simple instructions.

Such a program is far from the only one, since you can install the firmware on Android from a computer using a similar utility from the developer on almost every smartphone.

recovery mode

In the "recovery" mode, that is, in the recovery mode, you can also reflash your device. As in any other case, you need to download the OS and move it to the SD card. It is worth noting that this Android firmware is produced without a computer.

In order to install a new OS on your phone, you need to go to the engineering menu or Recovery mode. To do this, turn it off, then hold down the power button and the volume down, up or the menu button at the same time (the combination may be different for each phone manufacturer, so you need to find out more).

Depending on the version of "recovery", our actions are as follows:

in the standard version, click apply update from external storage;

in the TWRP version - install ZIP;

in the CWM version - apply update from sdcard.

After the Android firmware of HTC or any other manufacturer is successful, you need to restart your smartphone and go through the initial setup.

You should pay attention to the fact that if all possible combinations were tried, but the gadget did not enter the "recovery" mode, it means that this function is disabled or absent in this device.

A couple of words

Once again, we recall a couple of important points that can save several thousand nerve cells from certain death:

Before installing the firmware on Android from a computer, you must make a backup copy of the data. This can be done using special utilities from both the official developer and the unofficial one. This will help to do if the flashing failed.
After flashing, hold the power button for 15-20 seconds. If it does not turn on, you can try to remove and insert the battery and try to turn it on again.
Rather, the flash card will have to be formatted. Even if there is a lot of information there, the new Android can create new partitions on top of the old ones, completely ignoring the latter. Therefore, before connecting a USB flash drive, it is best to reset all its contents to a computer.

Users of devices based on the Android operating system sometimes encounter incorrect operation of their gadget over time. This is usually due to the accumulation of system errors and other problems in the software part of the OS. If you do not attach importance to this in time, then over time your device may become completely inoperative. You can correct the situation and restore the previous speed and functionality of the gadget by flashing it via usb. Let's take a closer look at which programs for Android firmware via PC are best used.

If you still decide to use the program to update the firmware, then you should protect yourself in case of an unsuccessful outcome. To do this, it is recommended to make a backup ROM of your Android tablet or phone. More information on how to do this can be found on our website. By placing the backup along with the ROM file in the root directory of the device's memory, you will always have access to restoring the stock firmware. After you have secured yourself, you can start choosing a program for the firmware.

The first flash program for Android considered in the article will be the SP Flash Tool utility. Its peculiarity lies in the fact that it is intended only for smartphones based on MTK chips. Such processors, for example, have many Chinese branded gadgets: Lenovo, THL, Doogee and others. In order to successfully flash the device from a computer using the flashtool utility, you will need:

Computer.
A smartphone or other gadget that needs to be reflashed.
USB cable for connecting your phone to a computer.
Installed flashtool v3 or later.
Archive with the required firmware.
Drivers for your device.

The process of flashing an Android device with this utility is not complicated if you correctly follow the sequence of the actions necessary for this.

Let's take a look at the benefits of the app:

no paid features;
does not require activation;
simple and accessible interface;
Suitable for any smartphone and tablet based on MTK chip.

The main disadvantages include the following:

there is no version of the utility in Russian;
sometimes it may not find the device.

You can download the program on our official website.

fastboot

This program for Android firmware through a computer works through the console. Note that you may also need the Android Debug Bridge app for this. In addition, for the full use of the fastboot, you need an engineering SPL (gadget software loader), or an SPL with disabled security checks.

In order to see if fastboot mode is available for a smartphone, you need to reboot it via the Android Debug Bridge with the adbrebootbootloader command. At the same time, the top line should display "S-Off", which means the security check is turned off. If “S-ON” is displayed, then this version of fastboot is not suitable and you need to install another one.

Before flashing through this utility, as in the previous case, you need to install your device drivers on your computer. All actions that can be done using this program are performed by certain commands through the console.

The advantages of firmware via FastBoot is the versatility of this method. Since with the help of this utility different devices are flashed and you can download almost any firmware for android.

ROM Manager

ROM Manager is a technical application that is used for many different tasks, including installing firmware. Users have access to two versions of the program, paid and free. The latter will be enough for most owners of smartphones and tablets based on the Android OS. For the full operation of the application, you will need to get root rights. How to do it right you can read on our website.

Since in this article we are considering various programs for flashing an Android device, we will give all the stages of flashing with the ROM Manager utility:

Getting root rights.
Installing the ROM Manager program.
Back up system data. You also need to install the ClockWorkMod recovery image.
Download the firmware as a zip archive.
We flash the device.
If something went wrong, then we try to restore the system.

Among the main features and advantages of the ROM Manager program for Android, the following items can be distinguished:

firmware management (installation from a microsd card);
creating and editing backups;
control of access rights to applications;
creating and editing partitions in memory.

As you can see, installing firmware in this way is safe for your device.

Results

If you decide to update or reflash the operating system of your Android device, then first of all you need to create a backup copy. This will restore the functionality of the gadget in the event that something does not go according to plan. After that, you can start choosing one of the Android flashers.

If you have a smartphone based on the MTK chip, then the SP Flash Tool is the best choice. The ROM Manager application also has a number of other features that can attract the user. The FastBoot utility will be in demand only among people who are fairly good at commands in the console.

The firmware for a smartphone, the same Android that you use, is the operating system for the phone. Just like Windows for PC. If it flies, then we see on the screen an endless download with the logo of Android or the phone manufacturer. There are a lot of reasons why the firmware flies - this is both a virus infection and a short circuit at the moment the gadget is connected to a computer or charger. Initially unsuccessful (crooked) firmware, the phone slows down a lot due to the large number of junk files that cannot be deleted.

There are 3 main firmware methods.

With the help of a special program.
Through Recovery (more complicated way).
Individual instructions for a specific phone model (some models cannot be flashed in the usual way, for more information you need to look for information on special forums).

Important: flashing is the complete removal of all information from the smartphone and the installation of a clean OS, so you need to take care of a backup copy (if possible).

Be extremely careful when flashing a phone or tablet, it is important to follow the instructions for a specific program and phone model exactly. Attempts to reflash the phone by an inexperienced user can turn it into an expensive "brick".

In this article, we will analyze the 3 most common programs for replacing Android cell phone software through a computer.
