How to open the recovery menu. If Android does not boot into Recovery mode. What kind of animal is this

Our site has already managed to tell you before. Let us remind you that this is the so-called recovery menu, with which the user can, for example, reset all data or reflash his gadget.

There are two types of recovery menu (Recovery Mode): stock and custom. Stock is the same type of Recovery Mode that is installed by default. When flashing, a custom Recovery Mode can be installed.

And now - the most interesting part. We will talk about how to enter the recovery menu. And here an interesting quest may await the user - various devices this mode may run differently. How exactly? To begin with, we will tell you about universal method, and then we’ll go through specific brands of smartphones and tablets.

Universal mode

What's good about it? The fact that it is relevant for most modern devices.

• Turn off your device by pressing the Power key, then in the menu tap on touch button"Switch off".

• Once the device is completely turned off, you will need to press the Volume Down key and the Power key at the same time.

• Or - press the volume up key and the Power key at the same time.

• When the device starts up, you can release the Power key.

This is the most convenient way of all and the easiest to launch the specified mode.

How to enter Recovery on Samsung?

For new models: press the volume up key, Power and the central Home key.

For older models, a universal method is used: pressing the volume up or down key, as well as Power.

Google Nexus

Volume down key + Power.

This will load Fastboot mode, and from there you can switch to Recovery Mode.

LG

Classic method: Volume Down + Power key. Please note that the volume up and down buttons on LG smartphones may be located on the back.

Xiaomi

Volume up + Power.

Meizu

Volume up + Power.

Please note that Meizu has its own menu with which you can reset the settings or update the firmware. This is not exactly a recovery menu.

HTC

Or increase volume + Power:

Or Volume Down + Power:

Huawei

Volume up + Power.

Or volume down + Power.

Motorola

First you will need to launch Fastboot Flash Mode, for which click on the button Volume Down+Power.

In the menu that loads on the screen, go to Recovery Mode using the Volume Down and Volume Up keys.

ASUS

Classic option. Either Volume Down + Power:

Either Volume Up + Power:

Sony

There are several ways.

The first one is simple: Volume Up + Power.

The second is a little more complicated: the Power button, then Up, the Sony logo appears and Up again.

Third method: Volume Up + Volume Down + Power.

How to enable Recovery Mode via terminal?

Download the Terminal Emulator application. Launch it, provide root rights (required).

Write the reboot recovery command.

The gadget starts in Recovery Mode.

How to enable Recovery Mode via a computer?

Install Adb Run and also necessary drivers. Connect the device to the computer, launch it on the computer command line, enter the adb reboot recovery command and press the Enter key.

Any device with Android OS starts in Recovery mode. This standard function. However, with the factory version you can perform too narrow a range of tasks. So, this is resetting the phone to initial settings, clearing the cache, as well as updating the system from the update.zip file. Obviously, users who are expanding their knowledge in the IT field are very dissatisfied with such a meager list. This is where specially developed Recovery Modes come to the rescue. CWM Recovery is a popular tool among Android users and a worthy replacement for the factory one.

Why do you need CWM Recovery mode?

Clockworkmod Recovery (CWM) is a famous alternative to factory recovery mode developed by Koushik Dutta. You can install it on most Android devices. CWM Recovery helps even in situations that sometimes seem hopeless to the average owner. That is why it is necessary to know about its existence, and also be able to use it.

CWM mode has many options

What exactly does the utility do:

CWM: installation instructions

ClockworkMod is sewn into the internal memory of the device in place of the factory mode. In some cases, work is carried out on the gadget itself with access to Root rights, and in others - on a PC.

The article covers such basic methods as Rom Manager, FastBoot, Rashr and Odin. For many devices, companies themselves produce separate utilities, for example, Acer Recovery Installer for Acer devices. CWM is implemented into the device memory on these devices also through ADB software, which is suitable for devices manufactured by HTC.

Rom Manager: Rooting and embedding

Rom Manager is a utility created by the CWM developers. It is available for download on Google Play Market. Allows you to install CWM Recovery on the device itself without using a computer and a USB cable. Before using it, you must root the device, that is, obtain administrator rights.

Obtaining Root rights

The procedure is simple and can be easily carried out using special software. As an example, you can take the Framaroot program. Anyone can navigate its simple and intuitive interface, even without instructions.

Download the app from the store and open it. In the drop-down line, give preference to the “Install SuperSU” or “Install SuperUser” item. Click on the drop-down window

Select a method for obtaining Root rights. Follow the advice - restart the device for the changes to take effect.

For the changes to take effect, restart the device

Launching Rom Manager

Now is the time to use the program:

Launch the software and click on the first section of Recovery Setup, and then click on ClockworkMod Recovery. Select Recovery Setup

Find and select the device model from the list of available ones. If the model is not in the list, then this method of flashing Recovery is not suitable and you need to use another one. After confirming the action, the files will begin to download, as indicated by the progress bar. Next, a notification will pop up stating that you need to grant Root rights to the program. Then the CWM installation itself will be carried out. Click on ClockworkMod Recovery to install

Although the method is easy, it has a drawback: it is not suitable for all devices, as mentioned earlier. Before you start using this method, it would be logical to first determine that this program is compatible with the gadget. The list is available on the official Rom Manager website.

FastBoot Mode: Complex Method

Installation method CWM with using FastBoot will require skill from the user, since it is much more complex than the previous one. It runs not on the device, but on the computer. It is recommended to use it only if you already have skills in such operations. Before installation, you must download it to your computer or laptop. certain files. This list also includes the Android SDK platform, available for Windows, Mac and Linux.

Preparatory stage

What you need to have before installing CWM using FastBoot mode:

The Android SDK utility will help you install the necessary Android SDK Tools and Android SDK Platform tools packages:

Go to the bottom of the official page. There will be three options. In this case, it is the Windows version. Click on tools_version-windows.zip.
Download the Anroid SDK zip archive for Windows from the official website

Extract all contents from the archive to drive C. Open and click on tools. The android file needed to download the packages directly is there. Double click on the file and the manager is open.
Find android file in the unzipped folder and open

Check the box to the left of Android SDK Platform-tools and click Install 1 package.

Select Android SDK Platform-tools and click Install package

Standard Acceptance Request license agreement. Check the Accept License box and then click Install. The direct installation of the packages necessary for the firmware, which were mentioned earlier, will begin.
Accept the license agreement

After the installation process is complete, find platform-tools in tools_version-windows. It will contain important fastboot and adb files.
The fastboot and adb files are located in the tools_version-windows folder after installing the Android SDK Platform-tools package

What else needs to be done before starting the firmware itself? Judging by the list above, you need the recovery-clockwork.img file. This is one of the key tools for further work. Downloading it won't be difficult, but it doesn't end there. It is important to place this file in the platform-tools folder. For further convenience in the firmware, you need to rename it to recovery.img.

Place the file in the platform-tools folder

Get straight to the point!

Now everything is ready for the CWM firmware itself, so you can safely get to work. Given below detailed description action in which it is quite difficult to get lost.

First, connect the device to be flashed to your computer via USB. Runs simultaneously FastBoot mode(combination of power and volume down keys). Although this combination works most often, it is not suitable for everyone. In some cases, this is the Home key and the same volume reduction. When the first option doesn't work out, nothing will happen if you use the second.
Start your device in FastBoot mode

The main procedure is performed on the command line. First you need to open it. In the window Windows terminal(press Win + R keys) write cmd command.
To open the command prompt, go to Start and type cmd

The command line is immediately ready to use. Type cd / immediately after the last entry and press Enter.
Type cd / and press Enter

The next line in the black window should look like cd path_to_folder_platform-tools. Press Enter again.
Enter the command with the path to the folder

The next step is the adb devices command. It will help determine whether the PC sees the device. Next type adb reboot bootloader. Wait until the device turns on as a bootloader. Finally, go to the final part of the firmware: enter fastboot flash recovery recovery.img. and press Enter.
The adb devices command will help determine whether the PC sees the device

The level of complexity, as you can see, is high, so before the procedure it is strongly recommended to check that this method is suitable for the device, since it may not work in all gadgets.

In practice, this method is good if the manufacturer of the device is HTC.

Rashr app The installation method using Rashr is convenient and easy to perform; it is recommended for beginners. However, ironically, it also requires administrator rights. You can get them in a few steps. detailed instructions

was given earlier in the section on Rom Manager.

How to work with Rashr

When the program is already on the phone, you need to open it and provide it with previously acquired Root rights upon request. Then everything is simple:

Select CWM Recovery. Click CWM Recovery

The software will provide available versions Recovery for this device to be flashed, such as the touch ClockworkMod and the option with key control.
Select Recovery from the list of options available for your device

Select the most suitable version and click Yes to confirm the download.
Click Yes to confirm download

After downloading, a notification will pop up that the new recovery has been successfully downloaded and installed. To go there, click Yes.
To go to Recovery, click Yes

Odin: solution for Samsung

The previous three methods are suitable for different models devices. The same method is effective for Samsung devices. This is a proprietary utility, so it cannot be used for devices from other manufacturers. There are many versions of this application. The latest one is Odin 3.09.

Here the standard factory version of Recovery is changed to a modified one using a PC, as with FastBoot:

Download Samsung Odin from the official website.
Download Odin program on PC

Click the Start button and wait until the firmware is completed successfully.
Click the Start button and wait for the firmware to finish

How to enable CWM Recovery mode after flashing

Once CWM mode has been installed using one of the above methods, you need to check if it works. You can launch ClockworkMod Recovery:

Possible difficulties

During the installation of an alternative Recovery Mode, in particular CWM, various difficulties and errors may arise. Which of them are the most common and how to solve them?

CWM Recovery does not recognize the memory card

CWM makes it possible to update your phone using an archive. When opening Recovery, the user sees a message that the flash card cannot be mounted. After installing another card, even with less memory, the problem disappears. The reason lies in the Windows system. The fact is that it diverges from card formatting standards. To format formatting in accordance with the specification of SD/SDHC/SDXC flash cards, and not just in standard form, it is recommended to use specialized software, for example, SD Formatter.

CWM does not see the internal memory of the device: problem solution

When the files to be recovered are on internal memory, and therefore can only be restored from there, a problem may arise. When connected USB cable to the PC and enable “USB Debugging”, the program reports that the Android device is not detected and you need to enable “USB Debugging”.

To solve this problem:

Recovery menu doesn't work

If when you launch the alternative recovery mode (volume + Home button or power) a picture appears with a lying robot, then the recovery was flashed, but when you restarted the device it was overwritten by the stock Recovery.

The problem is solved as follows.

Flashing a new Recovery mode means getting new functionality. Firmware methods vary in complexity, but ironically, the simplest of them require access to Root, that is, device administrator rights. When choosing a firmware method, you need to be guided by the phone model first. Rom Manager is not suitable for all devices. For HTC, the FastBoot method is more suitable, while for Samsung it would be more correct to choose Odin.

If you have ever tried to flash an Android tablet yourself, you have probably come across the concept of “Recovery”. Today we will talk in detail about what this thing is, why it is needed at all, and of course, how to enter it.

What is Recovery

Recovery mode is a special boot mode for Android devices that allows you to full reset operating system settings, reflash the device, make a backup copy of the entire system or its individual partitions (as well as restore these partitions later) and some other things. At the same time, for this mode to work, the functionality of the operating system itself is completely optional. This is why the recovery menu is often accessed when the device no longer works in normal mode. And this is precisely why this mode is called “recovery” (from English “recovery”).

How to log into Recovery

To boot recovery, the device's hardware buttons are usually used. The most common combinations are:

However, some manufacturers may come up with “something like that,” so you have to search and experiment.

If everything is done correctly, a lying robot will appear on the device screen, on top of which there will be a menu with commands.

Another way to download recovery is special applications, with which you can reboot your smartphone or tablet into recovery mode directly from the operating system itself (for example, Reboot menu). However, it is worth keeping in mind that these applications require .

Navigation in recovery mode is carried out mainly using the volume buttons, and selection using the power button. There are also devices in which only the volume down button is used for navigation, and the volume up button is used to confirm the choice.

To all of the above, it is necessary to add one important detail. The functionality of the recovery mode itself is by no means universal, and can differ quite significantly depending on the device. Particularly distinguished in this sense are “noname” tablets from China and some B-brands, whose recovery does not have any list of commands at all.

Most of the articles in the X-Mobile section are devoted to hacks and tweaks that require obtaining root rights, modifying the firmware or replacing it with a custom one. However, not every reader is ready to subject their smartphone to such operations, fearing that they can turn the device into a brick or lead to instability in operation. Today I will debunk these myths and show that even in the most stalemate situation, bringing a smartphone back to life is not so difficult.

Destroying myths

Let's talk about what it really means to “turn a smartphone into a brick” and what other pitfalls can await the user on the way to changing the system and installing custom firmware. What glitches can be caught in this case and is it possible to kill a smartphone by reflashing it incorrectly? Will you lose the warranty forever or can the smartphone be returned to its previous condition? Can custom firmware really fail a smartphone owner at the most inopportune moment and are they worth it?

Myth 1. Incorrect flashing can kill a smartphone

A fall from the fifth floor can kill a smartphone, but not flashing it. The main problem that anyone who wants to reflash a smartphone faces is that during the installation of the firmware, a failure may occur, which will lead to its inoperability, and the smartphone will actually turn into a brick.

All this is true, but only on paper. To understand why, it’s enough to understand how the process of flashing a smartphone works and what system components are used in this case. To be able to install third-party firmware on a smartphone, you need to unlock the bootloader (not in all cases), get root and install a custom recovery console (ClockworkMod or TWRP), capable of installing firmware with any digital signature.

The recovery console is stored in a separate partition of the internal NAND memory and is in no way connected with the installed operating system. After installation modified version console, it will be possible to flash custom firmware or even another OS (Firefox OS, for example). If a failure occurs during the installation of the firmware, the smartphone will not be able to boot it, but the recovery console will remain in place, and all you need to do is boot into recovery again and reinstall the firmware.

In addition, any custom recovery console contains a backup/restore function, which allows you to make a backup copy of the main firmware and restore it unchanged (with all applications, settings and data) in the event that something goes wrong. In fact, the smartphone can be returned to its original state.

You may ask: what happens if the installation of the Recovery Console itself fails? Nothing, in this case the opposite situation will turn out when operating system will remain in place, and the console will be lost. To deal with it, you just need to re-flash recovery directly from Android.

Hypothetically, one can imagine a situation where both the firmware and the recovery console are killed (although this is quite difficult to do), but even in this case the primary bootloader, flashed in permanent memory smartphone.

Conclusion: it is impossible to kill a smartphone by installing third-party firmware through a custom recovery console. Either the recovery or the primary bootloader will always remain in place.

Myth 2. Custom firmware is unreliable

Firmware differs from firmware. In the vastness world wide web You can find a huge number of Android builds for every taste and color, and most of them are really slag, which can lead to instability in the operation of the smartphone and loss of some functionality. Therefore, the first thing to remember is that you should only deal with serious custom firmware developed by large teams of experienced developers. First of all, these are CyanogenMod, Paranoid Android, AOKP, OmniROM and MIUI.

Second. There are two types of firmware: officially supported and ported by third-party developers. The same CyanogenMod, for example, has an official version for the Nexus 4 smartphone, but does not have one for the Motorola Defy. But for Defy there is an unofficial port of CyanogenMod 11 from a developer with the nickname Quarx. The difference between them is that the CyanogenMod team is responsible for the support and proper operation of the first, while the second is Quarx personally. Official firmware versions are usually fully functional, but the correct operation of the latter depends on the third-party developer.

Well, third. There are stable and development versions of the firmware. Stable versions of CyanogenMod have the index M (CyanogenMod 11.0 M7, for example). This firmware version usually does not contain bugs. Development versions (in the case of CyanogenMod these are daily nightly builds) may contain bugs and are therefore not recommended for everyday use.

Conclusion: if you install a stable official version of the “normal” firmware on your smartphone, the risk of encountering bugs is minimal. Everything else is for experimenters.

Myth 3. Software that requires root rights can brick a smartphone

In theory, an application with root rights can do anything with the smartphone's firmware, including erasing it completely. Therefore, you need to be extremely careful with such software. The software we talk about on the pages of the magazine is completely safe and tested in our own skin. In addition, for all the time I have been using smartphones on Android (and this is starting from version 1.5), I never I haven’t encountered a situation where software with root support killed a smartphone.

Software distributed through Google Play, usually fully corresponds to the stated characteristics, and if it led to a brick or left a backdoor in the depths of the smartphone, it would not last even a week in the store. In any case, here you need to follow the “trust but verify” rule and carefully read the instructions for using root applications.

Myth 4. Root rights make a smartphone vulnerable to viruses

What makes a smartphone vulnerable to viruses is not root rights, but the bugs used to obtain them. Rooting tools and viruses can exploit the same Android vulnerabilities to gain root privileges, so the fact that the device is rooted does not change anything. A well-written virus will not ask for permissions in a standard way, giving away his presence, he will instead take advantage of the same vulnerability to obtain them covertly.

Moreover, having root, you get the opportunity to install the latest Android version(in the form of custom firmware), in which these bugs have already been fixed. Also, do not forget that most custom firmware allows you to disable root or create white lists of applications that can use these rights.

Myth 5. A rooted smartphone may fail

Software designed to obtain root does four simple things: launches an exploit that allows you to gain root rights in the system, mounts the /system partition in write mode, copies the su binary required to obtain root rights in the future to the /system/xbin directory, and installs the SuperSU or SuperUser application, which will take control whenever any application requests root privileges using su.

None of these steps can crash or kill the smartphone. The only thing that can happen is that the exploit will cause a segmentation fault and the smartphone will reboot, after which it will continue to work normally.

Myth 6. By getting root and installing custom firmware, I will lose the warranty

The guarantee is lost not from the fact of obtaining root, but due to its detection by the service center. Most devices can be unrooted using the Universal Unroot app or by reinstalling the stock firmware using official application from the manufacturer.

There are, however, two exceptions to this rule. The first is the Knox system, pre-installed on new smartphones and samsung tablets, such as Galaxy S4, S5, Note 3 and Note 10.1. Knox provides an increased level of Android security by responding to any firmware modifications and installation of third-party kernels and firmware. If the user performs these actions, the system sets a trigger that confirms the fact of the modification. The trigger is implemented in hardware (eFuse chip), so it cannot be reset to its initial position. On the other hand, it is not entirely clear whether it will refuse service center on this basis, repair the device. Second: the eFuse chip is installed on some other devices (for example, smartphones from LG), and it also allows you to accurately determine whether the smartphone has been rooted or flashed.

If we talk about custom firmware, everything is more complicated. Typically, the flashing operation requires unlocking the bootloader, and this can be done either using special exploits or using the smartphone manufacturer's web service. In any case, the unlocked bootloader will definitely indicate that the smartphone did not belong to a blonde.

On some smartphones, it is possible to lock the bootloader back, but you should learn about this separately, and also keep in mind that the newly locked bootloader will most likely receive the status Re-locked, and not Locked, as it was originally (this happens on HTC smartphones, For example). The only exceptions here are smartphones and tablets of the Nexus line, the bootloader of which can be locked and unlocked in three clicks without any dancing with a tambourine, and no one will find fault with anything.

INFO

On Linux, ADB and Fastboot can be installed separately from the Android SDK. On Ubuntu: sudo apt-get install android-tools-fastboot. On Fedora: sudo yum install android-tools.

To prevent Knox from interfering with root applications, you can disable it using the following command from the terminal: su pm disable com.sec.knox.seandroid.

conclusions

Getting root and flashing a smartphone are absolutely safe operations that cannot brick the smartphone for purely technical reasons. The only exception is an attempt to hack the bootloader in order to unlock it. In this case, the eFuse chip (if the smartphone has one) may work and block the ability to turn on the smartphone.

Fortunately, today smartphone manufacturers either prefer not to block the ability to turn on a smartphone with a hacked bootloader (by setting a trigger indicating the fact of such an action, as Knox does), or implement a special web service that allows you to painlessly unlock the bootloader with loss of warranty on the smartphone. which saves users from having to risk breaking the bootloader.

Problems that may arise during flashing

So, now let's talk about what problems can arise when getting root and flashing and how to deal with them.

Scenario one: after an unsuccessful flashing, the smartphone stopped booting

Unsuccessful flashing can be caused by several factors: the battery died and the firmware was only half filled; the firmware turned out to be faulty or intended for a different smartphone model. In the end, there was simply not enough space on the smartphone, which can happen when trying to install the latest version of Android on a smartphone that is three or four years old.

Outwardly, all these problems usually manifest themselves either in endless resets of the smartphone to the initial manufacturer logo, or in the so-called boot loop, when the boot animation plays on the screen for more than five to ten minutes. There may also be problems with the screen (multi-colored ripples) and a non-working touch screen, which also prevent the use of the smartphone.

In all these cases, it is enough to do one simple thing: turn off the smartphone by long pressing the power button, then turn it on while holding down the volume down button (some smartphones use a different combination), and after you get into recovery, reinstall the firmware (Install zip from sdcard - > Chooze zip from sdcard) or restore the backup (Backup and restore -> Restore). Everything is easy and simple.

Scenario two: the firmware works, but recovery is not available

This can happen after a failed installation or update of the Recovery Console. The problem is that after rebooting the smartphone and turning it on while holding down the volume down button, a black screen appears, after which the smartphone either resets or freezes.

Solving this problem is not easy, but very simple. You can install the recovery console on the vast majority of smartphones using the TWRP Manager, ROM Manager or ROM Installer applications. They themselves determine the smartphone model, download and flash the required recovery, without requiring a reboot. If you can’t restore the console with their help, just find instructions on the Internet for recovery installation to your device.

Scenario three: neither firmware nor recovery is available

To be honest, it is difficult for me to imagine such a scenario, but, as practice confirms, it is quite real. There are two ways to get out of this situation: use fastboot to upload recovery to your smartphone, or use a tool from the manufacturer to install stock firmware. We'll look at the second method in more detail in the next section, and I'll talk about fastboot here.

Fastboot is a tool that works directly with the device’s primary bootloader and allows you to upload firmware to your smartphone, recovery, and unlock the bootloader (in Nexus devices). Fastboot support is available in many smartphones and tablets, but some manufacturers block the ability to use it. So you will have to consult the Internet about its availability.

To access fastboot, you will need drivers and Android SDK. When they are installed, open the command line, go to the SDK installation directory, then to the platform-tools directory, turn off the smartphone, turn it on with the volume buttons pressed (both) and connect it using a USB cable to the PC. Next, you need to find the recovery image in .img format for your device and run the command:

$ fastboot flash recovery image.img

Or even force the smartphone to boot recovery without actually installing it:

$ fastboot boot image.img

In the same way you can flash official firmware update:

$ fastboot update update-file.zip

You can find a recovery suitable for your device either on the TWRP website or in the XDA-Developers and w3bsit3-dns.com forums.

We return the smartphone to its original state

In this section, I will talk about ways to return your smartphone to clean stock, no matter what state it is in. These instructions can be used both to unbrick your smartphone and to remove traces of rooting and flashing. Unfortunately, I can't tell you about everyone possible models, so I’ll focus on the four most popular flagships: Nexus 5 (I call this copy the control one), Galaxy S5, LG G2 and Sony Xperia Z2.

Nexus 5 and other Google phones

Restoring Nexus devices to their original state is easier than any other smartphone or tablet. In fact, it is so simple that there is not even anything to talk about. In fact, all you need to do is install the ADB/fastboot drivers (on Linux you don’t even need them), download the archive with the firmware and run the script. The whole operation looks like this step by step:

1. from here.
2. Download and install Android SDK.
3. Download the archive with the firmware for the desired device from the Google website.
4. Turn off the device, turn it on with the volume buttons pressed (both) and connect using a USB cable.
5. Unpack the archive with the firmware and run the flash-all.bat (Windows) or flash-all.sh (Linux) script and wait for the operation to complete.
6. We launch the command line, go to the directory with the Android SDK, then platfrom-tools and execute the fastboot oem lock command to lock the bootloader.

For those who are interested in what the script does, here is a list of commands:

Fastboot flash bootloader bootloader-DEVICE-NAME-VERSION.img fastboot reboot-bootloader fastboot flash radio radio-DEVICE-NAME-VERSION.img fastboot reboot-bootloader fastboot flash system system.img fastboot reboot-bootloader fastboot flash userdata userdata.img fastboot flash recovery recovery.img fastboot flash boot boot.img fastboot erase cache fastboot flash cache cache.img

Galaxy S5

Co Galaxy smartphone S5 is a little more complicated, but overall quite simple. This time you will need the Samsung Odin application, which will be used to flash the smartphone’s firmware. Sequencing:

1. Download and install latest version Samsung USB drivers from here.
2. Download and install the latest version of Odin from here.
3. Go to the website samfirmware.com, enter the SM-G900F model in the search, find the firmware marked Russia, download and unpack.
4. Turn off the smartphone and turn it on with the Volume Down and Home buttons pressed, wait five seconds until a warning message appears.
5. Press the volume up button to put the smartphone into Odin mode.
6. We connect the smartphone using a USB cable.
7. Launch Odin, press the PDA button and select the file with the extension tar.md5 inside the directory with the unpacked firmware.
8. Click the Start button in Odin and wait until the firmware process is completed.

As I already said, this operation will return the smartphone to its original state, but will not reset the trigger, installed by the system Knox (if she was in standard firmware). Therefore, the service center may refuse to repair.

LG G2

Restoring the LG G2 to its factory state will also not cause any problems. The number of steps in this process is somewhat larger, but they themselves do not require special preparation and knowledge. So, what to do to return the G2 to factory firmware:

1. Download and install ADB Driver Installer from here.
2. Download official firmware(Europe Open 32G or Europe Open) from here.
3. Download and install LG Mobile Support Tool, as well as FlashTool (goo.gl/NE26IQ).
4. Turn off the smartphone, hold down the volume up button and insert the USB cable.
5. Expand the FlashTool archive and run the UpTestEX.exe file.
6. In the window that opens, select Select Type -> 3GQCT, Phone Mode -> DIAG, in the Select KDZ file option select the firmware downloaded in the second step.
7. Click the CSE Flash button at the bottom of the screen.
8. In the window that opens, click Start.
9. In the next window, select the country and language and click Ok.
10. We wait for the firmware to finish, and then turn off and turn on the smartphone.

This is all. But keep in mind that, as in the case of Samsung, the smartphone will still have Rooted status, and this cannot be fixed.

Sony Xperia Z2

Now about how to return to factory condition Sony smartphone Xperia Z2. As in the previous two cases, this will require stock firmware And official utility for firmware. You launch the utility on your PC, connect your smartphone using a USB cable and start the update process. Step by step it all looks like this:

1. Download and install ADB Driver Installer from here.
2. Reset your smartphone to factory settings.
3. Download and install Flash Tool from the official Sony website and latest firmware from here.
4. Copy the firmware file to the C:/Flashtool/Firmwares directory.
5. Turn off the smartphone and turn it on while holding down the Volume Down and Home keys.
6. We connect the smartphone to the PC using a USB cable and launch the Flash Tool.
7. Click the button with the lightning icon in the Flash Tool. In the window that opens, select Flashmode, double-click on the firmware in the list that opens.

WARNING

In many smartphones, an unlocked bootloader will not allow an over-the-air update.

In 90% of cases, unlocking the bootloader will entail deleting all data from the smartphone, including the memory card.

conclusions

Flashing a smartphone, and even more so gaining root access, is not at all such a scary and dangerous operation as it may seem at first glance. If you do everything correctly and do not resort to tools that unlock the smartphone’s bootloader, bypassing the manufacturer’s tools, you will not be able to brick your smartphone. Yes, in some cases you will have to tinker to get everything back in place, but what is better - to use a locked smartphone that does not allow you to do even half of the things that it is capable of, or to gain complete control over the device? In the end, reinstalling Windows on PC it doesn't scare anyone.

To switch to Recovery Mode, you need to use a bootloader or bootloader. Recovery Mode, in turn, is used to reset to factory settings, hard reset and flash the smartphone's firmware.

On Samsung smartphones There is a special Download Mode, which is separate from Recovery Mode.
