If your mobile device (smartphone or tablet) has stopped working normally, flashing it can help. You will learn how to reflash Android from the article below.

Modern smartphones and tablets Android based Today they have become very common devices that almost everyone has. To a large extent, this was facilitated by the influx of similar Chinese-made equipment. It is inexpensive, presentable on the outside and can be quite nimble on the inside. However, such devices very often work unstably, and at one point they may even stop working...

There is a 50/50 chance that reflashing your device can help you get your device back on its feet. And it is this process that today’s article will be devoted to. By the way, almost all the tools mentioned in the article for flashing the firmware of most Chinese devices can be downloaded below the article!

Firmware principle

Roughly, the process of flashing any phone can be compared to the process Windows installations on computer. However, if Windows can be installed on almost any PC, then Android installation contains many pitfalls. The fact is that the firmware contains not only the system itself, but also a complete set of drivers and programs suitable specifically for specific model devices.

Considering that the Chinese assemble their smartphones from everything that can be bought inexpensively from various manufacturers, it is not difficult to state the fact that the same external copy of, for example, Samsung S7 can be based on completely different platforms! Actually, the main problem when updating firmware is precisely finding one that will ideally suit your device in all respects.

You can search for firmware on the Internet by the model name of your device. However, if it is not branded, but a Chinese copy, then it may be difficult... It will be necessary to carry out preliminary tests in order to at least approximately find out what kind of “stuffing” Uncle Liao crammed into the phone. First of all, we are interested in the build platform and its ALPS number.

To find out this information The most reliable way is to open the device and “punch” on the Internet the numbers indicated on motherboard. However, not every device can be disassembled without damage. Therefore there are a number software diagnostics They can be installed both on the smartphone itself (for example, AIDA64 or CPU-Z) and on a computer. In the latter case, you will also need to install a special driver (it will also be needed when flashing the firmware).

After installing the driver, you will be able to use one of the most commonly used tools for “Chinese” based on the MT65xx platform - the MTK Droid Root and Tools program:

When you connect your device with a USB cable to your computer, the program will scan it and give you a certain piece of information that you can use as a starting point when searching for the required firmware. The most important data is platform version(Firmware) and system build number(Build number). Knowing them, you will be able to more accurately determine which firmware to download (and sometimes there are a lot of them!)

So, let's assume you have found the required firmware for your device model. Download it and be sure to read the installation instructions. It can be installed using:

• standard recovery (the easiest way);
• modified recovery (most often CWM or TWRP);
• flasher or flasher program (for example, Odin, SP Flash Tool and so on.).

In any case, before installing the firmware, it is very advisable for you (if, of course, the device starts up) to make a complete backup of all data on the device and its firmware. If you don’t do this, you risk getting a so-called “brick” instead of your favorite device, which will go into “eternal reboot”. But more on that below, and now let’s look at the Android firmware options.

Firmware via standard recovery

If you are very lucky, the official firmware for your device can be installed from a memory card through standard recovery. For example, I was lucky with my experimental Cubot GT99 (see screenshot above)! All you need to flash it is to drop the archive with the required files into the root of the flash drive (only, preferably, there are no other archives there):

When the firmware is already on the SD card, you need to turn off the device and boot it into recovery mode. To do this, as a rule, you need to hold down "rocker" volume up(less often down) and power button. When the boot method selection menu appears, you still need to use the same “rocker” down to select the mode "Recovery Mode" and press the rocker up (less often the power button) to go to recovery:

In the menu that appears, use the volume rocker to select the item "apply update from external storage" or "Install ZIP from SD Card" and apply it by pressing the power button. The firmware process will start and we just have to wait for it to finish:

Firmware via modified recovery

Standard recovery is a useful thing, however, not all firmware can be installed with its help. You can install with it only official system assemblies signed by all certificates. If you want to experiment with custom firmware, then you will need to install a custom recovery for yourself.

The most popular and widespread versions today are the already mentioned above CWM and TWRP. Ready-made assemblies of such recovery exist for most popular models devices. However, for Chinese smartphones you'll have to look for them. True, in some of them, custom recovery is already installed by default, which greatly simplifies various experiments.

The principle of flashing a device via custom recovery is similar to that described above. The only difference is that it can be used to install almost any suitable ZIP archive, even if the files in it do not have any signatures. Moreover, if the firmware is not suitable, the recovery will automatically roll back to the backup you created (you didn’t forget to make it, did you? ;))

Entering custom recovery is usually done using the same combination as stock recovery (volume rocker + power button). To install firmware from an SD card to CWM you will need to follow the path install zip from sdcard - chooze zip from sdcard. In this case, it is usually advisable to disable signature verification in the section toggle signature verification:

In TWRP, to achieve the same result, you need to go to the section Install and follow the prompts. By the way, in this recovery, control is performed not by physical buttons, but by means of a touchscreen (although there is also a similar CWM touch assembly).

Custom recovery is a very useful thing. In addition to firmware, you can use it to root your device, connect in debugging mode via ADB, manage phone memory partitions, etc. The only trouble is that such a useful thing has been ported to only a few devices...

Firmware using PC

One way or another, even if your device does not have a custom recovery build, you can flash it using a PC. To do this you will need at least:

1. Driver for the computer to recognize your device.
2. Firmware, suitable in all respects.
3. Backup of current firmware on the SD card in case the new firmware does not work.
4. Worker USB cable to connect the device to a computer.
5. Firmware program Your phone or tablet model (aka flasher).

From the above list, we are most interested in the last point. For popular branded devices, there are also branded flasher utilities. For example, for Samsung - Odin, for LG - LG GSM Multi or PC Suite, HTC - HTC Sync, etc.

Let's look at the principle of firmware using an example Odin for Samsung. First, you need to connect the device in download mode to the computer. You can enter this mode by simultaneously pressing the sound rocker up, the Home button and the power button on the device when it is turned off. After connecting the phone in this mode, Odin should recognize it as a connection on one of the COM ports.

Now in "AP" field You need to select the archive with the firmware (usually in .tar or .tar.md5 formats). Check that the "Auto reboot" and "F. Reset Time" options are active, then you can press the button "Start". If everything is fine, the firmware will begin downloading to the phone and installing it:

For Chinese devices, most of which run on the MediaTek platform, there is its own universal program for firmware SP Flash Tool(or just Flash Tool).

The principle of the firmware here is as follows. Open the program on "Download" tab(usually opens by default) and click "Choose" button opposite the field. The firmware selection dialog will open. It must first be extracted from the archive into a folder (preferably in the root of the disk, like the flasher itself) and contain a text scatter file with a map of the system partitions.

When a file is selected, a table of available partitions will open. Usually you need to uncheck the "Preloader", "Cache" and "Userdata" boxes, but for more detailed information, read the instructions specifically for your device model. The last step is to press the button "Download". Now all that remains is to connect it to the computer COMPLETELY TURNED OFF phone and wait until the files are copied:

"Brick" and what to do with it

As you can see, the firmware itself is not a very complicated process (if you consider that the bootloader is not locked on your device). But why then are so many people so afraid of her? But the thing is that the success of the firmware is never guaranteed and every time you risk getting the so-called "brick"- a device that does not boot at all or constantly reboots before turning on the system itself.

There can be, by and large, two options for “bricking”: a complete “brick” and with a preserved recovery. If you still have access to the recovery and you previously did system backup on a flash drive, then you can “unbrick” the device very quickly using the method of flashing the firmware or restoring the image (if there is such an option) through recovery.

If, due to unsuccessful firmware, the recovery partition was damaged, then the device can only be brought back to life by installing the correct firmware version on it. Here, as they say, you have nothing to lose and you can try different firmware until you find the right one! Usually such dances with a tambourine are required when working with Chinese phones, in which the developers themselves programmatically hide the platform version or hardware package.

In the most extreme cases, it may turn out that none of the firmware available on the Internet will suit you... If you are faced with such a situation, do not rush to despair! Firstly, over time (a couple of months or six months), an image of the firmware version you need may appear. Secondly, you can always ask for help from experienced users on the largest Russian-language forum w3bsit3-dns.com or the English-language forum XDA. Owners of “Chinese phones” can try their luck on the China-iPhone.Ru resource.

conclusions

General principles Android firmware, as you can see, are not particularly complex. However, this, alas, is only in theory... In practice, you may encounter various non-standard situations, which most often happen when trying to flash another Chinese device from an unknown manufacturer. Here everything can turn into a very confusing quest with an unknown outcome (that is why at the very beginning I wrote that the probability of success is 50/50).

In any case, when starting to work on Android firmware, the first thing you should do is MAKE BACKUPS! Secondly, don’t be too lazy to read the instructions that other more experienced users write on the forums (if these instructions exist). After all, sometimes even checking the wrong box can turn your device into a “brick” with literally one touch!

One more thing. Always start work with a fresh mind and with at least a couple of hours of time to spare. This will give you the opportunity to calmly consider your actions if something suddenly goes wrong. In general, may Android firmware always be successful for you!

Updating or installing firmware can eliminate many problems related to the operation of Android devices A. During long-term 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 begins to freeze and reboot on its own. And if factory reset() did not lead to a positive result, the user can only update the software himself. Let's look at how to reflash a phone running on Android OS.

Types of firmware and methods of installing them

Installing Android firmware at home differs in many ways from installing other software. This process is more labor-intensive and associated with many risks. If you select the wrong software version or violate the update process, there is a possibility that your phone or tablet will become useless. However, having learned how much reflashing costs from professionals, many still decide to change the version software on one's own.

For flashing Android there is no single instruction that would fit all models mobile devices. It all depends on the manufacturer of the device and what software you plan to install.

All Android firmware is divided into two types:

1. Official. Supplied directly by smartphone manufacturers and usually only suitable for a specific brand. Such programs are considered the most reliable, so they should be used whenever possible.
2. Unofficial (custom). Developed by Android device users and small companies. They are used when reinstalling Android 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 begin to slow down even more. Therefore download executable file necessary 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 your Android device, you need to make a number of preparatory measures:

• download a software update program to your PC (Odin, Kies or SP Flash Tool and find a high-quality usb cable(if the reinstallation will take place using a computer);
• (if you plan to reinstall Android to an unofficial version);
• charge the gadget's battery to 100%;

The functionality of the installed software largely depends on its version and build. To prevent the new firmware from starting to conflict with the hardware after some time, you need to find out serial number mobile device:

Let's look at a more detailed procedure for updating Android on a phone using Samsung and Lenovo as examples, although these instructions are also suitable for many other brands.

Smartphone firmware from Samsung

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

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

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

After creating a backup copy, feel free to reflash your phone or tablet via your 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, do not under any circumstances disconnect it from the PC or perform other actions that could lead to a disconnection.

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

Replacing firmware on a Lenovo tablet via PC

Before flashing a Lenovo tablet, you need to understand that there is no software developed specifically for this brand. Therefore, we have to be content with universal developments. One such application is SP Flash Tool. Let's look at how to update software on Lenovo using this utility:

After you have succeeded in updating the firmware, check that all functions of the tablet are working.

Today we will talk to you about how to independently reflash a smartphone to Android via a computer. The procedure is not easy, and the firmware of each gadget has its own nuances, which you will have to clarify on specialized forums. But in general terms you will understand that when the right approach You can restore the device at home, install third-party firmware on it, or update the stock one to new version.

Firmware for an Android smartphone using a computer

To begin with, we will warn you that in this way you can “kill” your gadget. In the language of people who understand, turn it into a “brick”. In this case, without going to service center you won't be able to get away with it. You shouldn’t even bother flashing NoName firmware for gadgets from China; if you break it, they may not be able to be repaired at the service center.

Be that as it may, we live in the age of technology, the age of the Internet - world wide web, where, if you wish, you can learn literally everything: even the firmware of Android phones. Actually, what are you doing now? Well, let's get started....

Finding and installing the software required for firmware

It's no secret that for different manufacturers devices require different drivers. Fortunately, they can also be downloaded on the Internet. For example, you have a smartphone from Samsung– drivers for subsequent firmware can be found on the official website. There are also Alternative option without searching for drivers - just connect the phone to the computer, after which the operating system will independently select and download them (applies to owners of Windows 7 and newer versions of window operating systems).

The next task is to download the firmware itself. The most popular Russian-language resource with official and custom firmware is 4pda.ru. Go to the forum, look for your device and firmware there. Choose the one that is most interesting to you and download it to your computer.

Then you need to assign Superuser rights to the program, that is, give Root access. How exactly to provide it, see our previously written article.

Now we return to the already familiar website 4pda.ru, or more precisely, to its forum and download the CWM-recovery file for your gadget (it is important that it is specifically for your device, otherwise you risk turning it into a “brick”).

We write a zip archive with the firmware and Recovery downloaded earlier into the device’s memory, or better yet, onto an SD card.

We return again to installed program Mobileuncle MTK Tools, launch it and it’s in automatic mode will find CWM-recovery on your smartphone, you will only need to confirm the update process by pressing the “OK” button.

Preparing for firmware

Without a backup copy - nowhere! It will be useful to us in case of unsuccessful firmware to restore the device’s functionality. Go:


So, the backup has been created. To restore it, go to installed application CWM recovery, tap on the “Backups” item and select the recently created one there.

You should also save as a backup copy all data that may be erased during the firmware update of the device - contacts, photos, etc.:

To restore data from a backup copy, use the nearby “Restore” button - that is, “Recovery”. You will only need to indicate the path to the previously created backup and confirm its installation. As you can see, absolutely nothing complicated.

Installing firmware on an Android smartphone

So, the new Recovery is installed, now you need to log into it. First, fully charge your device. Turn it off and, using the combination of the Power and Volume Up buttons, go into Recovery. Depending on the device manufacturer, the combination may differ.

Here we select “Wipe cache partition” and confirm our actions;
Now let's move on to the most interesting part - installing the operating system. Click on “Install from sdcard”, then on “Choose zip from internal sdcard” and find the file with the firmware downloaded earlier;

We confirm our consent;

We wait for the installation process to complete, after which we reboot the device and wait for it to boot. Don't be alarmed if the first download takes longer than usual - that's how it should be.

What to do if the phone does not start after flashing the firmware

If the startup process of the smartphone has not progressed beyond the logo, it makes sense to reboot it again. Didn't that help either? Then reflash again. Otherwise, we need to roll back to the standard firmware and restore the Backup. You already know how to restore a backup, but how to roll back to an earlier one installed version firmware? There is only one answer - no way, it will have to be installed via a computer.

Let's look at the process using Samsung devices as an example:

If the method does not work, and this happens, the road to the service center is paved. We warn you: the names of the programs and drivers are different for all programs, but in general the installation process is similar, so it will not be difficult to figure it out. We hope everything worked out for you!
