Mobile devices have already become a part of our lives. Now a person cannot imagine existence without a smartphone or tablet. Devices based on operating system"Android". This OS was developed by Google, and now its market share is incredibly high. Apple's iOS and Windows phone an insignificant percentage of presence in mobile markets compared to Android. However, like all technology, devices on this platform tend to "fail". Various system failures are a hallmark of any operating system. No matter how advanced she is. Very often devices have to be reflashed. But not everyone knows that you can do without such drastic measures. Indeed, in any gadget on "Android" there is Android System Recovery 3e. How to use it and what is it all about? We will talk about this.

What is this animal?

What does Android System Recovery 3e mean? This is a kind of BIOS mobile device. Every operating system has its own BIOS - basic system I / O, which is able to work even if the main OS is damaged. Sometimes the BIOS is different from the standard one (as, for example, in Android devices). It serves to restore the health of a smartphone or tablet, apply critical updates, or reset to factory settings. The Android System Recovery 3e menu has many items that correspond to one or another action. But the trouble is that the names are written in English language. Therefore, many do not even know how to properly use the recovery.

That is why this article was written. Android System Recovery, the instruction for which is absolutely necessary, is powerful tool for setting up and resuscitating a smartphone. You need to know everything about how to use this recovery in order not to spend money on masters. Doing everything yourself is much easier and cheaper. We will analyze each item of the recovery menu and tell you everything we can about it. So let's start.

How to enter the recovery?

It depends on the specific model devices. In some devices, you need to hold down the power button and the "Volume +" key. But sometimes there are smartphones for which this is not enough. Older models with a mechanical home button require you to press that button as well. Some devices require the simultaneous pressing of the power and "Volume" buttons. There are those who need to hold down the power key and both volume buttons. This applies only original devices from well-known manufacturers.

But there are also frankly "Chinese" gadgets with an incomprehensible operating system and a "crooked" translation. Standard Methods entering the recovery in these cases may not work. There are several options here. First: study the documentation of the smartphone (if any) and find the key combination you are looking for. But this option is not for everyone. Most of these devices either do not have any documents at all, or there is no Russian language in the documents at all. The second option: find the desired combination by pressing all the buttons in turn. And now let's move on to the Android System Recovery 3e menu items.

Reboot system now

This menu item does full reboot devices. After selecting this option, the smartphone will load the standard operating system "Android" without any changes. Usually this item is used upon completion of all manipulations in the recovery. Or in the event that you booted into this mode by accident. Although how this can be done by chance is unknown. Be that as it may, Android System Recovery 3e, whose instruction manual is simply vital for the user, has such an item. And this has to be taken into account.

The menu item should be used last. That is, when all operations are completed, all components are updated, factory settings are reset and firmware is installed. This is the essence of the reboot: let the device apply all the changes made. True, after some of them, the smartphone may not boot at all. But that's a completely different story.

Apply Update from External Storage

This menu item allows you to apply the update that is on the memory card. By the way, new firmware is also installed through this item if the main OS is not loaded. There are several sub-items in this Android System Recovery 3e menu. How to flash a new OS? For this you need to go to this menu and select Choose ZIP from SD Card if the firmware is in ZIP format. If it's just an update file, then you should select Apply Update From SD Card. This is how any device is flashed with the help of recovery. Simply copy the firmware file to the root of the memory card, go into the recovery and select the desired item.

There are other sub-clauses in this paragraph that apply in non-standard situations. It is possible to check the MDSUM of the firmware file. This option checks the file for integrity and if something is wrong, immediately issues a warning. You can also check the firmware file for compatibility with the device. These are the informational options of Android System Recovery 3e. Instructions as such are not required. If there are errors, then you do not need to install this firmware. That's the whole story.

Wipe data. factory reset

Here is a very important point. This option is able to restore the device without any firmware. This tool resets the operating system of the gadget to factory settings. Naturally, everything that was on the smartphone will be deleted: applications, photos, music. In general, everything that was in internal memory phone. Android System Recovery 3e, whose instruction manual is discussed here, was created just to revive the device without serious interference with the firmware. And this option allows you to perform this operation.

This function is also used before installing any firmware. It is necessary to reset the phone to factory settings before flashing. Otherwise, the new operating system will be unstable. But that's not the worst. If you do not return to the factory settings, then the firmware may not be installed at all, and then the user will receive a completely "dead" smartphone. There is no instruction in Russian, but the one that is, clearly says that it is necessary to use the Wipe Data & Factory Reset item before each device firmware.

Wipe Cache Partition

Another useful command in Android System Recovery 3e. The instruction for the recovery says that you need to use this option in tandem with Wipe Data. If the previous item clears the internal memory of the device, then this one clears its cache. Namely, the working files of applications are stored there. Of course, if this is not done before the firmware, then nothing bad will happen. It's just that in the future, when installing new programs, the cache of the device will grow to incredible sizes. As a result, the smartphone will work very slowly. But this is not so scary, since there are many programs for cleaning the cache of the Android OS. And they work great.

It is also recommended to select this function after a factory reset has been done. This will help the smartphone become even "cleaner", which will positively affect the performance of the operating system. The instruction in Russian for Android System Recovery 3e recommends performing this procedure after the reset. Until the device is rebooted. Then everything will be as it should be.

Wipe Battery Stats

This feature helps to refresh the battery of the device. After clicking on this item, the battery cache begins to be cleared, into which Current state battery, its nominal capacity and other necessary parameters. By resetting the battery usage statistics, it will be possible to slightly extend its life. Yes, and the new firmware will work more adequately with the battery. For some reason, many "gurus" of "Android" dismissively refer to this option. But it's actually very helpful. However, it is not recommended to use it too often. Just before flashing the device.

Mounts. Storage

Here are the controls for the internal and external memory smartphone. This item allows you to clear the memory card or built-in memory, format it or attach it as a drive directly from the recovery. This section can be used if you forgot to transfer the firmware file to the memory card, and there is no desire to reboot the smartphone into the operating system. In order to mount the device's memory card as a drive, select the Mount USB Storage item. Once the connection is established, the computer will automatically install required drivers for work.

After the connection is established, you can do anything with the memory card: format, clear, copy required files etc. In order to unmount the USB flash drive, you should select the Umount USB Storage item on the smartphone screen in the recovery. After that, it will be possible to move on to other recovery points and perform further resuscitation of the device on its own.

Recovery errors

Sometimes there is such a common error in Android System Recovery 3e as canceling the installation of a firmware or package. It can occur for several reasons: the file with the firmware is damaged, incorrect information in the binary file, or the firmware simply does not fit this device. But there is another option: a factory reset was not performed before the firmware. It's good that they can be easily fixed in the same recovery. There are several ways to do this.

So, if an error occurs due to a broken firmware file, then you should download it, connect your smartphone to your computer, go to the Mount & Storage menu item and select Mount USB Storage. After that, you can re-copy the firmware to the root of the memory card. If you forgot to make a "wipe", then there is nothing easier than moving up a few levels and selecting the appropriate menu item. But the Android System Recovery 3e "No command" error is very rare. It only appears when the user tries to install an ADB update. Usually this method does not work. As a result, this error appears. So it doesn't make sense to use this method. Still nothing will work.

Conclusion

So, let's sum up. We have tried to describe android features System Recovery 3e. The instruction that resulted from this attempt will help novice users of the Android operating system learn how to restore the health of their smartphone with their own hands. Which will ultimately lead to broadening your horizons and good money savings.

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

Why do I need CWM Recovery mode

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

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

Rom Manager: Root rights and sewing

Rom Manager is a utility created by 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 need to root the device, that is, get administrator rights.

Although the method is easy, there is a drawback in it: it is not suitable for all devices, as already indicated 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: The Complicated Method

The method of installing CWM using FastBoot will require skill from the user, as it is much more complicated than the previous one. It does not run on the device, but on the computer. It is recommended to use it only if you already have skills in such operations. Before the installation itself, you need to download certain files to your computer or laptop. This list also includes android platform SDK 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 required Android SDK Tools and Android SDK Platform tools:

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

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

Check the box to the left of Android SDK Platform-tools and click on 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 on 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 completed, in tools_version-windows find platform-tools. It will contain important files fastboot and adb.
The fastboot and adb files are located in the tools_version-windows folder after installing the Android SDK Platform-tools

What else needs to be done before starting the firmware itself? Judging by the list above, you need a recovery-clockwork.img file. This is one of key tools for further work. Downloading it is not difficult, but this is not the end of the matter. 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

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 flashing device to the computer via USB. Runs at the same time 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 sound reduction. When the first option fails, 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 Windows terminal window (press the Win + R keys) type the command cmd.
To open command line, go to "Start" and type cmd

The command line is immediately ready for use. Write cd / right after last entry and press Enter.
Type cd / and press Enter

The next line in the black window should look like cd path_to_platform_folder_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 if the PC sees the device. Next, type adb reboot bootloader. Wait until the device turns on as a bootloader. Finally, proceed to the final part of the firmware: enter fastboot flash recovery recovery.img. and press Enter.
The adb devices command will help determine if 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 Rom Manager section.

How to work with Rashr

First you need to download the application itself. It is located in free access in the Play Market (Rashr- Flash Tool). You can also watch the program on a third-party site, but you must beware of suspicious web pages so as not to catch a virus.

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

Select CWM Recovery. Click CWM Recovery

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 last 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 on the official website.
Download Odin program on PC

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

How to enable CWM Recovery mode after flashing

After the CWM mode has been set 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 occur. 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 the phone using the 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 the standards for formatting the card. In order to format according to the specifications of SD/SDHC/SDXC flash cards, and not just in the standard form, it is recommended to use specialized software, such as SD Formatter.

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

When the files to be recovered are on internal storage, and therefore can only be recovered from there, a problem may arise. When connecting USB cable to the PC and turning on "USB debugging" the program reports that android device not detected and you need to enable "USB Debugging".

To solve this problem:

Recovery menu not working

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

The problem is solved in the following way.

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