Mobile devices have already become quite an integral part of our lives. Now a person cannot imagine existence without a smartphone or tablet. Devices based on the Android operating system are extremely popular. This OS was developed by Google, and now its market share is incredibly high. Apple's iOS and Windows Phone have a negligible presence in mobile markets compared to Android. However, like all technology, devices on this platform tend to glitch. Various system failures are a hallmark of any operating system. No matter how advanced it may be. Very often devices have to be reflashed. But not everyone knows that it is possible to do without such radical measures. After all, any Android gadget has Android System Recovery 3e. How to use it and what is it even? This is what we will talk about.

What kind of animal is this?

What does Android System Recovery 3e mean? This is a kind of BIOS of a mobile device. Any operating system has its own BIOS - a basic input/output system that can work even if the main OS is damaged. Sometimes the BIOS is not similar to the standard one (as, for example, in Android devices). It is used to restore the functionality 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. Therefore, many people do not even know how to use recovery correctly.

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

How to enter recovery?

This depends on the specific device model. 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 pressing this button as well. Some devices require you to simultaneously press the power and volume buttons. There are also those who must hold down the power key and both volume buttons. This applies only to original devices from well-known manufacturers.

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

Reboot system now

This menu item performs a complete reboot of the device. After selecting this option, the smartphone will load the standard Android operating system without any changes. Typically, this item is used after completing all manipulations in recovery. Or if you loaded into this mode by accident. Although it is unknown how this can be done accidentally. Be that as it may, Android System Recovery 3e, the instruction manual for which is simply vital for the user, has such a clause. And we have to take this 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 a reboot: to allow the device to 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 located on the memory card. By the way, new firmware is also installed through this point if the main OS does not boot. There are several sub-items in this Android System Recovery 3e menu. How to flash a new OS? To do this, you need to go to this menu and select the Choose ZIP from SD Card item if the firmware is in ZIP format. If this is just an update file, then you should select Apply Update From SD Card. This is how any device is flashed using recovery. Simply copy the firmware file to the root of the memory card, go into recovery and select the desired item.

This paragraph has other subparagraphs 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, it 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 for them. If there are errors, then you do not need to install this firmware. That's the whole story.

Wipe Data. Factory Reset

This is a very important point. This option can restore the functionality of the device without any firmware. This tool resets the gadget's operating system to factory settings. Naturally, everything that was on the smartphone will be deleted: applications, photos, music. In general, everything that was in the internal memory of the phone. Android System Recovery 3e, the operating instructions for which are discussed here, was created precisely in order to revive the device without serious intervention in 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 the firmware. Otherwise, the new operating system will be unstable. But that's not the worst. If you do not return to the factory settings, the firmware may not be installed at all, and then the user will receive a completely “dead” smartphone. There are no instructions in Russian, but the one that is there clearly states that it is imperative to use the Wipe Data & Factory Reset item before each firmware update of the device.

Wipe Cache Partition

Another useful command in Android System Recovery 3e. The recovery instructions say 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, this is where the working application files are stored. Of course, if this is not done before installing the firmware, then nothing bad will happen. It’s just that in the future, when installing new programs, the device’s cache 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 clearing the Android OS cache. 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 have a positive effect on the performance of the operating system. The instructions in Russian for Android System Recovery 3e recommend performing this procedure after the reset. Before rebooting the device. Then everything will be as it should be.

Wipe Battery Stats

This feature helps you refresh your device's battery. After clicking on this item, the battery cache begins to be cleared, into which the current state of the battery, its nominal capacity and other necessary parameters are recorded. By resetting the battery usage statistics, you can extend its life a little. And the new firmware will work more adequately with the battery. For some reason, many Android “gurus” are dismissive of this option. But in fact it is very useful. However, it is not recommended to use it too often. Only before flashing the device.

Mounts. Storage

Here are the controls for the internal and external memory of the smartphone. This item allows you to clear a memory card or built-in memory, format it, or attach it as a drive directly from 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 your smartphone into the operating system. In order to mount the device's memory card as a drive, you need to select Mount USB Storage. As soon as the connection is established, the computer itself will install the necessary drivers for operation.

Once the connection is established, you can do whatever you want with the memory card: format, clear, copy the necessary files, and so on. In order to unmount the flash drive, you should select the Umount USB Storage item on the smartphone screen in recovery. After this, you can move on to other recovery points and carry out further resuscitation of the device on your own.

Recovery errors

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

So, if the error occurs due to a broken firmware file, then you should download it, connect the smartphone to the computer, go to the Mount & Storage menu item and select Mount USB Storage. After this, you can copy the firmware again to the root of the memory card. If you forgot to “wipe”, then there is nothing easier than moving a few levels higher and selecting the appropriate menu item. But the Android System Recovery 3e error “No command” is very rare. It only appears when the user tries to install an update via ADB. Usually this method doesn't work. As a result, this error appears. So there is no point in using this method. Nothing will work anyway.

Conclusion

So, let's summarize. We tried to describe the capabilities of Android System Recovery 3e. The instructions that resulted from this attempt will help novice users of the Android operating system learn how to restore the functionality of their smartphone with their own hands. Which will ultimately lead to broadening your horizons and saving a lot of money.

Recovery Mode allows you to access a number of additional features that come with your Android smartphone or tablet. For example, you will be able to manually install system updates, wipe data/factory reset, or delete partition cache. If you have a custom recovery installed on your phone, then you will get even more options, such as installing custom images or even fine-tuning the device with various system tweaks.

You can enter Recovery Mode in different ways. We prefer the radical method of running the ADB command through the computer, but you can do everything much simpler. In principle, you just need to know a special combination of buttons specifically for your device (for example, “Increase sound” + Power). If you know her, then you can use a special application.

Method 1: How to enter Recovery Mode using Android application [Root required]

In this method, we will install a special application that initiates a quick transition to Recovery Mode. It's very simple.

Attention! The method only works if you have Root rights. If you don't know what it is, it's better to use method 2.

Step 1- Download the app from Google Play Store and install it.

Step 2- Open the application, where you will see 4 possible actions: Recovery, Bootloader, Restart and Shutdown.

Step 3— Click on Recovery, after which the phone will reboot and automatically enter Recovery Mode.

It's simple, right? This is the easiest way, unless of course you know the correct combination of buttons to enter Recovery Mode specifically for your device.

Method 2: How to enter Recovery Mode using ADB

Another way to get into recovery mode. Use this method if you do not know the special key combination or you do not have Root access, which is required for the first method.

Step 1— Make sure that Fastboot is installed and correctly configured on your computer. (how to configure them is the topic of a separate article)

Step 2— Connect your Android device to your computer using a USB cable and install ADB drivers if necessary.

Step 3- Go to the folder android-sdk-windows\platform-tools and open Command Prompt (Shift + right click anywhere in the folder -> Open Command Prompt)

Step 4— Enter the command “adb reboot recovery” (without quotes) and press Enter.

Step 5— Your device will turn off and then boot into Recovery Mode. Moving up and down is done using the volume buttons.

More experienced users of Xiaomi devices running Android are already aware of what Recovery and Fastboot modes are and what they are needed for. Therefore, this instruction is aimed more at beginners who want to learn a little more about the technical side of the device or who have decided to update the firmware. So what is it Recovery and Fastboot on Xiaomi, how to turn them on and off?

1. Recovery mode

Recovery mode, or recovery mode, is a special menu that allows you to perform certain actions with your smartphone. There are two types of them: stock and custom.

Stock Recovery

Installed with official, factory firmware. It is quite meager in its capabilities. Usually there are only 3 functions: (clearing the Data partition) and connecting to Mi-assistant(Connect with MIAssistant).

Custom Recovery or TWRP

This is Recovey from third party developers. It is installed by you yourself, instead of the stock one (sometimes, sellers install non-official firmware, for example from MIUI Pro, and therefore, most likely, you already have a custom Recovery).

It looks completely different. Usually, when loading into it, a language selection menu first appears, which includes English. Actually, you need to choose it, unless, of course, you speak Chinese. The selection might look like this:

Or like this (here we can perform several tests, and also immediately get into recovery or fastboot):

Here are the wipes of various sections ( Wipe), and the ability to create a backup ( Backup) any information on your smartphone (including IMEI), and most importantly, what it is used for most often is firmware ( Install). And in general, there are still a lot of interesting things. We will not go into detail, because... This is a very broad topic. Perhaps we will make a separate instruction on it.

How to log into Recovery?

This is done very simply:

1. Turn off the smartphone
2. Press and hold the volume up and power buttons. Hold it until the download starts.

Navigation through this menu is done using the volume keys. Confirm your choice with the power button. Custom Recovery also supports touches.

How to exit Recovery?

1. Finding the point Reboot, select it and confirm with the power button.
2. If for some reason the first step did not work, then simply hold the power button for a long time.

2. Fastboot mode

Fastboot mode - necessary for connecting your device to a PC for the purpose of flashing firmware, installing custom Recovery, etc. One might say, a technical mode for deeper work with a smartphone.

How to enter Fastboot?

To enter fastboot mode on smartphones Xiaomi, necessary:

1. Turn off device
2. Press the volume down and power button. Wait until the smartphone vibrates and release them. A rabbit wearing a hat with earflaps should appear.

How to exit Fastboot?

1. You must hold the power button for 15-20 seconds. The phone will begin to reboot and your normal desktop will appear.

We hope that this instruction will help beginners deepen their knowledge of the technical side of a smartphone.

Like any operating system, Android has a special boot mode when the device turns on, but the system itself does not boot. This mode is called Recovery Mode, or recovery mode in Russian. This mode is present in any Android device and allows you to reset parameters, change firmware, restore firmware from a backup, or simply in case of a freeze. It is noteworthy that, unlike root rights, using Recovery Mode is not dangerous, and therefore is not blocked by the developer in any way. This function can be used by absolutely everyone and completely officially. Let's take a closer look at how to enter recovery on any device running Android, and what each menu item is responsible for.

Recovery Mode provides access to the system functions of the device

Ways to enter Recovery mode

On the device itself

Standard method. The principle of entering Recovery Mode is the same for all devices - when you turn it on, you need to hold down several buttons. Most often this is volume up, but the following options may also occur:

• Samsung - power on + volume up + “Home”.
• LG - power on + volume down.
• Google Nexus, HTC - power on + volume down, then tap Recovery.
• Certain Lenovo, Motorola models - power on + volume up + “Home”.
• Sony - power button, after double vibration, hold down the volume up.

If for some reason you cannot enter Recovery Mode using standard means, try checking the instructions. The listed combinations are valid in almost all cases and will work both to enter the standard recovery menu and the custom one. In addition, you can run it even when the tablet does not boot or the system freezes.

If you have root rights, you will need the Terminal Emulator application installed (https://play.google.com/store/apps/details?id=jackpal.androidterm). After installation, you will need to enable superuser rights and enter two commands: first su and then reboot recovery. The device will reboot.

Via computer

A prerequisite is that USB debugging mode is enabled (Settings - For developers - USB debugging, or select the appropriate item when connecting to a PC). Therefore, if this mode was previously disabled, the tablet will not start and you will not be able to use it.

You will need the ADB Run program (http://cloud-androidp1.in/Android/PC/Project_Site/AdbProgramm/), a cable and a working device.

1. Connect your device to your computer.
2. Launch the ADB Run program.
3. In the program menu, press 4 and then 3 in sequence.

The device will reboot into Recovery Mode. You can perform the procedures you need.

How to use Recovery Mode

As we have already said, there is both a standard recovery and a custom or custom one. Many experienced users claim that the capabilities of the first one are quite scarce, so it is better to install the unofficial one. We'll talk about them a little later, but now we'll look at what Recovery Mode menu items you can find on your device.

Install zip from sdcard - installation of an archive with updates saved to a memory card. Through this menu, root rights are obtained and the firmware is installed.

Wipe data/factory reset - wipe data/reset settings to factory settings - completely clear the system partition, reset all settings to their original state. All apps and settings will be removed, but your media files will remain intact. Used for critical errors, system failures, or when new firmware is being updated. A particularly effective remedy in cases where the device does not turn on.

Wipe cache partition - clearing the system cache - the system partition in which temporary files and all program settings are stored. It is recommended to do this when the firmware is changed.

Backup and restore - system backup and restoration from previously created backups.

Mounts and storage - for correct operation, all sections of the system must be correctly mounted and connected. Often, this procedure is performed automatically, but sometimes something has to be corrected manually. You can also clear one of the partitions. We advise you to use this method only if there is a specific need, otherwise the file system will not load and the tablet will not work.

Advanced - additional settings, including rebooting Recovery Mode, clearing the dalvik cache, resetting system application permissions. Most often used by professional programmers.

Management, unless otherwise indicated, is carried out through (moving through the list) and power (selecting a menu item). In some cases, selecting is done with the volume up, and scrolling is done with the volume down. In any case, the system must indicate exactly how to manage menu sections. There are designs with touch control.

Unofficial Recovery

As mentioned above, the standard Recovery Mode very often has somewhat limited capabilities, so it is best to use third-party, unofficial developments. The most popular are two of them - ClockworkMod recovery (abbreviated CWM) and TeamWin Recovery Project (abbreviated TWRP). Both developments have excellent functionality and allow you to very quickly and conveniently modify or change the firmware, obtain root rights, reset settings to factory settings, or restore a backup copy.

Many instructions for upgrading and flashing Android require you to perform actions from the Recovery menu. What kind of mode this is and why it is needed you will learn from this article. What is Recovery (recovery) - this is a special Android boot mode in which:

• Perform a full Android data reset
• flashing a smartphone
• get Root rights

How to log in to Recovery? The Recovery menu is usually found in all Samsung smartphones and tablets, but is absent in other brands of Android smartphones, but you can easily add it by flashing this section to your Android device.

If the device has a Recovery menu and it has not been changed, then it is called STOCK, but if there was no Recovery menu and it was flashed, then the name is CUSTOM. There are mainly two types of custom: CWM and TWRP, less common are 4ext, Philz CWM, (different development teams).

How to log into Recovery
