First, you need to understand that the phone's operating system is the same as the computer's OS. And in order for the phone's performance to always be high, it is worth periodically updating the operating system.

There are, of course, non-standard situations when a purchased phone malfunctions after some time, the operating system begins to work incorrectly, and the phone does not respond to requests.

In this case, reinstallation is the only possible step to correct the situation (unless, of course, there was mechanical damage the device itself).

So how do you reinstall Android on your phone and tablet?

There are so many ways to reinstall.

First and the easiest way is to go to the “About phone” section. It's in settings. In it, select “Software Update” and start scanning.

Of course, it is worth remembering that your phone must be connected to the Internet, otherwise your efforts will be useless. If a newer version is found than is installed on your phone, the device will prompt you to install Last update(unless of course you have the automatic system update ticked).

Second the method is more labor-intensive. Everything will need to be done in “manual” mode. It is not recommended to use it if you are not very well versed in these issues.

After all, you don’t want the phone to not work or start at all. Then only service center and several days of waiting, plus, of course, financial costs.

But if you are an experienced user and you are not afraid of difficulties, then this option is for you. Moreover, there are big differences in the official versions of updates and the user ones, which are posted on the Internet on various sites and forums.

Official ones, as a rule, are very meager in terms of opportunities, which cannot be said about those that people offer. Administrator rights and many other useful things can be opened here.

Let us also add that not all phones and not all Android firmware can be updated. For example: version 2.3. cannot be updated. Owners Galaxy phones from Samsung they still only dream about the possibility of updating.

Fly phone, also not easy to update in manual mode. There are other difficulties different manufacturers. Let's look at the reinstallation using this phone as an example:

— Open the file downloaded to the computer and run it. We agree with what the program suggests. When the installation is complete, click “Finish”.

- Now with via USB connect the phone to the computer and switch it to debugging mode. When the computer sees the Android device, it will prompt you to install it. Click “Install”.

— After the installation process, we reboot the phone.

The approximate algorithm is also suitable for other phones. But it is worth remembering that you will do all actions at your own peril and risk. Therefore, how you update Android on your phone is up to you.

System reinstallation process

Before reinstalling Android on your device, copy all important data from the main memory to a flash device or PC. Any phone or tablet also has a special function - backup data. With its help, you can place user settings on external media or in the cloud to virtually completely restore personal information on the device. It is recommended to perform this every time you change the firmware, update the device or install new drivers. Reinstallation operating system Android can be done using several methods (relevant both on a phone and on a tablet):

• Reinstallation via computer using a USB cable;
• directly on your Android phone.

Both options are suitable for installing official builds and custom firmware versions. Select the reinstallation package you need and follow the procedure described below.

Many Android devices also have a " Hard Reset", which resets the device to factory settings without affecting the OS kernel. Often, with the help of such manipulation you can get rid of viruses, software errors and freezes on your smartphone or tablet.

Installation via computer

Many firmware versions can be installed using the Fastboot program. After installing the utility, download the firmware you need, connect the device with a USB cable to the computer and follow the following steps:

1. 1. Unpack the archive into the “Program-tools” folder, where the “adb” and “fastboot” files are located (in the example the folder is called “adb”).
   2. Necessary . To do this, you need to enable USB debugging on the device, and run command line(Win+r). In the window that appears, enter the command “cmd”. We write the following (after each request we put “Enter”):
      
   3. Now the Android device will reboot in the appropriate mode.
      
   4. Before flashing the firmware, each partition must be formatted. Use the “fastboot erase” command, then enter the name of the desired partition.
   5. Also, you need to flash the corresponding folders using the request “fastboot flash->partition name->firmware file name”
      
   6. Often the entire firmware can be installed using the “flash all” command.
      
   7. At the end you will receive a message that the installation is complete.
      
   8. Reboot your device and enjoy new firmware.

For some phones and tablets there are special programs- installers. For example, on Samsung there is an Odin utility. It doesn't matter what device you have (or Samsung Galaxy, or Samsung Nexus), this installer is adapted to work with everything model range companies.

Reinstalling Android OS on a phone and on a tablet via a computer is practically no different, the main thing is to follow the points listed above.

How to reinstall the system on Android

Many users of devices on this platform have to think about how to properly reinstall Android on their phone. This step is often prompted by the system itself, which, due to its openness, provides wide scope for experimentation. Despite this, you should be very careful and think about how advisable it is before the procedure itself.

Why is it worth reinstalling Android?

Users most often want to change the system in their smartphone or tablet for the following reasons:

1. Lack of device support from some manufacturers. Even the most well-known companies often do not want to release the latest versions of the OS for relatively outdated devices so that their owners buy new smartphones. But there is another way out - installing custom firmware based on a new version of Android, which fixes errors, carries out various optimizations and eliminates security vulnerabilities.
2. The desire to get a “clean” version of the OS. The fact is that almost all famous manufacturers of Android devices equip them with their own shells with numerous additions, which are not always appropriate. For users tired of an overloaded OS, firmware without unnecessary software will be a real breath of fresh air. And the device itself will work faster and more stable.
3. Availability of products from other manufacturers who were able to make their firmware more optimized and beautiful.

Don’t forget about forced flashing when the device stops functioning normally, and resetting to factory settings does not solve this problem. In such cases, it is best to completely “destroy” the existing firmware and completely install the new one. Before this procedure, be sure to create a backup copy of the necessary information and applications.

Preparation for the procedure

If you need any applications installed on the old OS, you need to create a backup copy of them before reinstalling Android on your tablet or phone. This is best done using the Titanium Backup program.

Since in most cases, flashing the firmware will delete all contacts in the phone’s memory, they also need to be saved. You can do this in several ways:

1. Upload contact list to Google account. To do this, go to the settings of the “Contacts” application, select the “Export” option and tap on the “Google” button in the pop-up window. After flashing, to restore your contact list you only need to log into your account.
2. Create a file with the extension “.vcf”, from which contacts can later be transferred to almost any phone. To do this, you need to follow a procedure similar to saving to your account, only in the last step select “Phone memory”. It is best to save the file on your computer, since some data is often deleted from the firmware during the flashing process. internal memory device, and sometimes from an SD card.
3. Save contacts to SIM card.

It is also advisable to save photos, music and videos on your computer.

General principles of reinstallation

There are a huge number of ways to reinstall Android, but they can all be divided into two groups:

1. Using a computer.
2. Without the use of additional devices.

To reinstall the firmware without the help of a computer, you will need Recovery, a program for restoring the functionality of your smartphone. It is installed by default by the manufacturer in all devices, but you can use the official version only if you are going to flash the “native” OS.

To do this, you just need to download the firmware from the manufacturer’s official website, place it in the phone’s memory, go to Recovery and select the “Install zip” or “Update” menu item, depending on the device.

To log into Recovery, you must:

1. Turn off the device.
2. Press and hold the key combination responsible for launching Recovery. You can find it in the documentation for your smartphone or tablet, but the most commonly used combinations are “Power button + volume up”, “Power button + volume down”, “Power button + volume up + volume down”.
3. In some cases, after this you will also need to select Recovery mode from the list.

To install unofficial firmware without a PC, you must first download custom Recovery: TWRP, ClockWorkMod, etc. It can be installed only with root access, for which you can use standard programs such as Framaroot and KingRoot. On devices with processors from MTK, you can install Recovery using the MTK Droid Tools or Mobileuncle MTK Tools program.

In the case of devices with Snapdragon, Kirin and Exynos processors, in most situations you will have to resort to flashing the firmware via a cable using a PC. To do this, you can only use programs and drivers from the manufacturer, but the process itself is more intuitive, understandable and safe. To implement it, you just need to download and install all the software from the manufacturer, copy the firmware to your computer and follow further instructions.

The basic rule for flashing firmware via a cable using a PC: under no circumstances should you interrupt the process until the program gives a signal that it is complete. This way you can significantly reduce the likelihood of getting a “brick”.

Features of the procedure for different devices

If your device has official firmware based on Cyanogen Mod, you can simply download the CyanogenMod Installer installation package, install it on your smartphone and PC, and then run the Cyanogen utility on the latter. Most often, only owners of flagship devices from HTC, Samsung and Google have this option.

As for Chinese devices, manufacturers such as Xiaomi, Meizu and Huawei block the bootloader, so flashing such smartphones can be extremely difficult. Official unlocking of the bootloader is often available only to residents of the Middle Kingdom, and unofficial methods are fraught with the loss of smartphone functionality.

Therefore, it is better to update the products of the above brands only by legal means- through the official Recovery and using the “Update” utility, which can be found on the desktop or in the “About phone” menu item.

The approximate algorithm is also suitable for other phones. But it is worth remembering that you will do all actions at your own peril and risk. Therefore, how you update Android on your phone is up to you.

No matter what operating system you use, sooner or later it starts to slow down and Android OS is no exception. When a malfunction occurs in the operating system, most users begin to think about how to reinstall Android. Most often, such a measure is actually quite effective and allows you to eliminate problems in the operation of your tablet or smartphone.

However, reinstalling Android is relevant not only in cases where there are problems with the OS. For example, many users decide to update Android in order to get a new version of the operating system, which is characterized by richer functionality. Whatever the reason for reinstalling the system, the solution will be the same.

It should be noted that before rebooting Android, you need to decide what exactly you want to get from this procedure. For example, someone decided to resort to such a measure for the purpose of , someone needs a more recent OS in order to be able to download applications whose developers did not bother with older versions of Android, others cannot use their device normally due to constant failures.

Of course, the solution to the problem will differ from the cause, although there are universal methods, which will be discussed in this article. Below we will look at how to reinstall Android by automatically updating the system and installing custom (non-official) firmware.

How to reboot Android (updating and flashing the system)

Before reinstalling Android, you should try to solve the problem with a regular reset to factory settings, of course, unless the reason for flashing the device was the desire to be able to download applications that are only available for the latest versions of Android. If resetting to factory settings does not suit you or this procedure does not achieve the desired result, you can proceed to updating the software.

How to Automatically Update Android OS

Before you reboot your Android (update the firmware automatically), you need to check if there is an available Android OS update for your smartphone or tablet. To do this, go to the device settings and open the “About device” section (depending on the device manufacturer, this section may have a different name, for example, “About tablet” or “About phone”).

After this, you will find yourself in a section with information about the Android version and firmware that is installed on your device. this moment. So, you need to find out if there are any updates available for your device. To do this, you need to select the “Software Update” item (other names for this section are also possible, for example, “System Update” or simply “Update”).

After that, click on the “Update” button (possibly called “Check for updates” or “Check now”).

Next, the system will check for updates for your device and if there are any, you will be prompted to update. If available updates no, the system will notify you that you have installed latest version Android. It should be said that a notification about the lack of available updates often appears in cases where the device has quite a old version Android OS. In this case, you will have to perform the update manually using special programs. More details about possible options We wrote about operating system updates in the article ““.

How to reinstall Android using unofficial firmware

If the option is to install official firmware for certain reasons does not suit you, then it makes sense to try custom (unofficial) firmware. If you really find good version custom firmware, you can significantly improve the performance of the operating system. There are several options for installing unofficial firmware, and in some cases you can even do without obtaining it. If you are seriously considering the option of installing custom firmware, then be sure to read the article ““.

Perhaps this is where we will finish this article. Now you know how to reinstall Android, all you have to do is choose the option that is most convenient for you.

The question is quite relevant among users of this OS, since Android, like other systems, sooner or later fails. And often, to get rid of them, there is only one option left - reinstallation. But failures are not the only reason to carry it out: quite often new versions are released on Android, the installation of which simply warms the user’s soul with its new functions and updated interface.
One way or another, you still need to reinstall the Android version on your phone or tablet (the methods for doing this are not so different for these devices, except that the interface may differ).

There are several ways to properly reinstall your system

The first and perhaps the simplest and safe way- This automatic update. In this case, you don’t have to be afraid of messing up, since the device will do everything itself.
To run automatic updates on your tablet (or phone), you need to turn on the Internet and find the corresponding option in the settings menu. Depending on the device, its name may differ, but usually it is “Software Update” or “Check for Updates”. After detecting it, we use it to check for updates available for the current tablet.
If for some reason the device does not have this function, or the device does not want to look for new firmware (system versions), you can easily find it in PlayMarket special applications to update Android OS.

Remember! It may happen that it is impossible to change the current version of Android to a newer one on your phone or tablet: sometimes developers do not provide updates for certain versions OS and device models. In this case, you can only reinstall the system again.
If updates are still found, the device will quietly begin the installation process. Before doing this, it is better to take care of the availability Wi-Fi networks or unlimited internet– otherwise, get ready to lose the lion’s share of your traffic.
The second method is relatively more complicated and usually takes more time. It is done manually using a computer and a USB cable.

Before you start reinstalling the system, you need to prepare:

1. The device must be fully charged. Even better - connected to power throughout the entire process;
2. You must know exactly what Android version you need. The “About device” option in the settings menu, or the information indicated on the packaging box, will help here;
3. Be sure to create backups- especially if you are reinstalling for the first time. To do this, you can use special programs (for example, NandroidBackup), or simply copy the “wload.bin”, “env.bin”, and “u-boot.bin” files from the device memory to the SD card. Then these files need to be copied from the memory card to the computer.

Then the “preludes” end, and the process of manual updating begins

So, we know the current version of Android, now we need to download the corresponding firmware to the computer. It is strongly recommended to download updates only from the developer’s website, or from 100% trusted sources.
After the firmware is received, format the memory card and create the “SCRIPT” folder in its root. We then copy the downloaded firmware files into this folder.
We turn off the device and insert a card already equipped with new firmware into it, turn it back on.

We're already close. Now the device will start installing the new Android OS automatically from the files we suggested. You shouldn’t disturb his “trance”, much less turn it off. The process may take quite a long time, so do not be alarmed. Once the installation is complete, the device will turn on itself, and you will see an updated (or simply reinstalled) Android.
And if it doesn’t appear, or appears incorrectly, then you always have backup copies at hand - everything can be fixed.

This method of reinstalling the Android version is very similar to reinstalling Windows With boot disk(LiveCD), and requires the same accuracy and precision in actions.

The third method is to use third-party programs on your PC

There are other ways to reinstall Android on your device, but they are not suitable for everyone:

1. 1. Reflash the OS using a special disk to search for and install updates on the device. The disk is often included with some popular models of tablets and smartphones;
2. 2. Or entrust the reinstallation to specialists. Although here you need to be attentive to the professionalism of the employee - there have been cases of a working smartphone being returned in a “brick” state.

In fact, flashing the version on Android does not require much effort - just a little patience and adherence to a clear action plan. There is no need to be upset if it turns out incorrectly the first time: reinstalling the OS is a delicate matter and requires some experience.
