Android system recovery 3e firmware. Android Step by Step: ClockWork MOD Recovery - What is it and why is it? recovery. What is it

Recovery Mode (recovery mode) - a special boot mode of the device, which allows you to reset to factory settings, backups and other system actions.

Most often it is used for when there is no access to the standard system settings. The procedure for entering Recovery is different for each manufacturer. For example, on Samsung smartphones you need to hold down the "power button + Home + volume rocker up." On Nexus devices - "power button + volume down". Management in the recovery itself is carried out using the volume buttons and the power button.

Attention! Opening Recovery is not a dangerous procedure and does not void the user's warranty, but further actions may lead to various consequences, for which you are solely responsible.

There are several types of recovery mode: stock and custom. Let's consider them in more detail.

Stock

Stock Recovery Mode comes with the device initially and does not differ in special functionality. In most cases, it contains the following items:

In many smartphones on Android 7.0 Nougat, the following functions appeared in the Recovery menu:

• Reboot to bootloader (direct download of mobile operating system to access the recovery mode and start the normal operating mode of the OS).
• (verification of signatures of all root files and their integrity).
• Mount / System (mounting the system and its partitions).
• View Recovery Logs (recovery logs).
• Run Graphics Test (start graphics test).
• Power Off (turn off the device).

Custom

Custom recovery includes a lot more features. Most often it is used to install and create a system recovery image (nandroid backup), it is also possible to wipe (clear) individual partitions, for example, data, dalvik cache, restore the phone to its original state without losing data, restore the rights of system applications, and so on. . The most popular are CWM and TWRP.

As you know, the Android operating system provides the user with a huge functionality, using which he can realize the full potential of his smartphone: from advanced settings using the engineering menu to a complete factory reset using a special mode - Android System Recovery 3e. What to do in this menu with a smartphone, you will learn from this article.

This setting mode was designed to work with system files and system settings. With it, you can activate or block almost all the functions of an Android device. Here you can carry out such complex manipulations as a complete cleaning or restoring the system in just a couple of clicks. Due to the fact that this menu plays an important role, getting into it is not so easy, but more on that below. In order not to harm your device, you need to know the mode items, their meaning in Android System Recovery 3e and what to do to carry out certain actions.

Launch Android System Recovery 3e

As mentioned above, launching this menu is not so easy. To get here:

1. Turn off the gadget;
2. Simultaneously hold down the volume rocker, the home button and the power key.

After a few seconds, the Android logo will appear on the screen, and then the android menu System Recovery 3e. What to do in it and what values ​​the menu items have - we'll talk about this later.

Assigning items in the mode

The very first and most important item is Reboot. It allows the user to restart the device.
To use the device's memory card as an external drive connected via USB, select Toggle USB strage.
There is also work with the CWM package. It is used to install native Recovery on the device.

By selecting "Instal from sdcard" (installing CWM from a memory card), you will find yourself in a subsection with items:

1. Installing CWM Recovery, which is preloaded on a memory card - Choose zip from sdcard;
2. Check md5sum sum – Check md5sum a file;
3. Find out the signature of the CWM package - Toggle Signature Verification;
4. Check CWM for compatibility with the device - this can be done by clicking on Toggle Sclipt Assert.

How to use Android System Recovery 3e for flashing, what to do on Lenovo or other gadgets? Use only proven features that you understand!

1. Reset all smartphone data - Wipe data / factory reset;
2. Wipe Cache allows you to completely clear the cache;
3. Wipe dalvik cache is used to clear the Dalvik cache;
4. To clear your battery usage history, use Wipe battery stat;
5. Format System completely removes all system files;
6. Format Date formats the data section;
7. Format cache deletes the cache data, but the files themselves remain in it;
8. Clearing cache core data - Format boot;
9. To completely format the device, use Wipe all partitions.

All the meanings of the menu items that we are talking about are completely identical for all gadgets running Android.

Backup / Restore - one of the most important sections, which is responsible for backing up and restoring data. It contains items:

1. Backup - creates a backup copy of data;
2. Restore - used to restore the factory firmware;
3. Advance Restore - used to restore individual data partitions;
4. Advanced Backup - can be used to copy partitions.

The next item is responsible for converting formats in Android System Recovery 3e. What to do in this menu? Here you can select different types of conversion to EXT4 and EXT3. Here's what this section allows you to do:

1. Convert/change a backup converts the device system;
2. Use Convert Data to convert data;
3. Change one of you backup is used to translate backup sections;
4. Convert Cache converts the cache;
5. Wipe data/factory reset is used to convert all partitions;
6. System formatting - format system, data - format data, cache - format cache.

Extra menu

In the Advanced section, you can perform such actions using the following commands:

1. File System Check checks the validation of system files;
2. Print Partition Info displays log information;
3. Copy recovery.log to sdcard is used to save copies of the recovery log;
4. Opening ext and ext2 formats on an SD memory card - Partition SD Card;
5. No - save my fat32 partition! stops partitions;
6. Use Fix Permission to fix permissions in /data/data.

And finally, the last item - Power Menu. It is used for power management:

1. Reboot Recovery reboots;
2. In Bootloader mode, use Reboot into Bootloader;
3. A simple reboot is done using Reboot;
4. Power Off - ordinary shutdown.

Thus, using this menu, you can implement a huge number of functions that are not available in the visual settings. If you have any questions, you can always ask them in the comments!

A lot of time has passed since then - at the moment CWM has version 6.0.x.x and is divided into two types: regular and touch version. In the first case, control and navigation takes place using the volume keys (louder - step up, quieter - step down) and the power button, which acts as a confirmation (a kind of analogue to the computer Enter'u), in the second - with the help of touches, not just So we have touch screens. There is no difference between them as such, except that the power consumption of the second option is slightly higher.

So, why can we use third-party recovery? First of all - to install custom firmware, of course. If we consider the extended functionality in general, then you have the ability to “roll back” the device to factory settings, clear (wipe, wipe) the cache and dalvik cache, create system recovery images (nandroid backup, nandroid, backup - backup), restore the rights of system applications and much more.

However, not CWM alone. There is also another popular and fairly widespread recovery, which, in my opinion, is much more convenient and thoughtful - Team Win Recovery Project (TWRP). It is completely based on finger control, has an optimized menu item size for this, and is much more logically structured. During the creation of backups, you can choose what exactly to save (which partitions). There is also a keyboard (outwardly similar to that of ICS / JB) and a terminal emulator that allow you to perform various actions without a forced reboot of the device. After the firmware, TWRP will helpfully offer you to clear the cache and dalvik-cache (which you need to do in CWM yourself). The easiest way to get TWRP is the Goo manager program.

It would seem, why then talk about CWM? In its last, sixth iteration, the algorithm for creating backups has changed - now instead of a huge 400 MB-1 GB file, only a 25 MB image is created that saves changes that were not in the previous backup. In addition, the whole procedure is much faster (in the region of 40-45 seconds), which makes life much easier, given the importance of performing this action before flashing.

How to install Clockworkmod on your device? Depending on the devices, the paths differ - somewhere you can get it using specialized utilities (ROM Manager in the Google Play Store or separate programs like the Galaxy Nexus / Galaxy S3 Toolkit), using command line or by changing the kernel. Consider the installation process through the Galaxy Nexus Toolkit 7.7.

We select your version of the phone and firmware, turn off the smartphone and, holding down both volume and power keys, enter it into Fastboot mode, and then connect it to the computer. In the Galaxy Nexus Toolkit, press the key 6: Flash Recovery.

You will be prompted to choose TWRP or CWM. Select item 1. Congratulations on a successful installation!

There are several ways to download CWM. The first way is directly from the OS (using the previously mentioned ROM Manager program), the second option is by selecting the Recovery item in Fastboot mode (on Galaxy phones, you need to hold down the volume key up + “home” + power). If you did everything correctly, then you will see a number of lines of English text on a gray background. What do they stand for? The names are similar to those in TWRP, so there should be no problems with migration.

Let's go through the points.

• Reboot system now - reboot the phone in Android
• Install zip from sdcard - install a zip archive from a memory card / device memory (on phones that have both sources of memory, there is a corresponding sub-item)
• Wipe data/factory reset - cleaning system data and restoring the phone to factory settings (or to a "clean" type of custom firmware; your multimedia files will remain intact), must be performed before installing a custom firmware that is very different from the currently installed one (everything is always indicated in ROM description)
• Wipe cache partition - clearing the cache partition, it is also necessary to do it before installing another firmware in order to avoid problems
• Backup and restore - creating restore points and directly restoring from them
• Mounts and storage - allows you to connect / disconnect a particular section of memory, as a rule, it is no longer required, because everything happens automatically. It is also possible to format one of these partitions (as a rule, it is also not required, unless you are going to return the phone to its original state completely)
• Advanced - advanced settings menu, where you can restart CWM, clear the dalvik cache (another action you need to perform when installing a theme / mod / firmware), mark up the device's memory, or restore the rights of system applications by default. The rest of the steps are irrelevant.

Third-party recovery is not only your first step towards changing the firmware or modifying the existing one, but also a convenient tool for everyday use, which, alas, cannot be said about the built-in solution. This article discusses the two most famous and popular recovery, however, there are other options for this or that device, but they are not “multinational”.

That's all for today, let me take my leave!

If you find an error, please highlight a piece of text and click Ctrl+Enter.

Many situations may lead to the need to reset the Android system, for example: frequent device freezes, the Android system cannot boot, or the gadget unlock password is lost. "Hard Reset" is a radical solution that allows you to return the device to a working state.

Looking ahead, I note that "Hard Reset" deletes data only from the device's memory, without affecting the SD memory card, although there is option 2 that allows you to affect it too.

Attention!!! All contacts, installed applications, messages, etc. will be deleted. Before starting the reset operation, it is highly recommended that you back up your phone data! One of the backup methods is .

Option 1. Recovery Mode

Turn off the device and boot into Recovery Modeby holding a few keys together. Each manufacturer has its own buttons:

• "+" on the volume rocker and the "ON / OFF" button;
• "-" on the volume rocker and the "ON / OFF" button;
• Volume "+" and "-" together and the "ON / OFF" button;
• Volume "+" and "-" together, "Home" key and "ON / OFF" button;
• In Chinese devices, hold down the volume key and connect the charger.

The volume up/down buttons allow you to navigate up and down the recovery menu, and the command selection is performed by the ON/OFF button. In the latest devices, control in "Recovery Mode" can be normal (touch).

Select "wipe data/factory reset", and confirm the system reset by selecting "Yes - delete all user data". Upon completion of the wipe, select the "reboot system now" option.

It will be a little more difficult to see the reset for Chinese phones. For example, in "iconBIT NetTAB Mercury XL" or "Samsung Galaxy S4 GT-I9500" clone, the recovery menu is in Chinese. If you have the same situation, the picture below shows the Russian translation of the "Recovery Mode" menu.

To navigate through the menu, use only the "-" volume key, because. the "+" key is used to go back one level up. To select the highlighted command, press the ON/OFF button.

To start a hard reset android settings in Chinese phones, you need to select the 6th item. The funny thing is, once selected, the command will be executed without confirmation.

After a few minutes of waiting, your Android device will boot up like it did the first time after purchase, possibly asking you to add a Google account.

Option 2: Restore and reset

In you can see an item such as "Restore and reset". It is designed to reset the system settings and restore from backup saved on the Internet.

Click on the "Reset Settings" option.

Scroll down and optionally check the box next to "Clear phone memory - card" to delete personal data from the SD memory card, such as photos, music and other user data. Click on the "Reset phone settings" button.

User data will be deleted and factory data will be restored.

Once again, let's talk about the Recovery menu, since almost always the instructions for flashing and upgrading Android provide for the performance of certain actions from the Recovery menu.

What is Recovery?

Recovery (recovery) or translated from English - Recovery Mode is a special device boot mode with which you can restore the system or install updates. This is an emergency mode necessary to restore the working state of the mobile device in the event of program failures, which resulted in the device turning off and the inability to boot it in normal mode.

With the Recovery mode, you can:

1. Reboot your tablet or smartphone.
2. Reset settings.
3. Install updates.
4. Configure and install firmware.
5. Get Root rights.
6. Delete your personal data in the system.
7. Restore the operating system and much more.

Remember that incorrect actions can harm the system. If important information is recorded on your tablet, it is better to save it on another device in advance.

Before using the recovery mode, carefully read the instructions. Each tablet has a different service menu, so the question of how to enter the Recovery menu on a tablet requires an individual approach.

How to enter Recovery?

The Recovery mode in each mobile device is visually different, but the login process is almost always carried out according to the same principle. In order to enter the Recovery system, you need to do a number of actions:

1. Turn off your tablet. At the same time, make sure that the battery is fully charged or connect the tablet to the network.

2. Switch to Recovery mode by pressing a combination of some buttons. Since different tablet manufacturers offer different hotkey combinations, we will give some of the most common key combinations for entering the recovery menu.

The main key combinations for entering the Recovery:

• Simultaneously holding down both the "volume" keys and the "power" key;
• simultaneously pressing one of the "volume" keys and the "power" key;
• simultaneously hold down one of the volume buttons, the Home button and turn on the device.

The buttons are held until the recovery mode appears on the display.

On some Chinese devices there is no Recovery mode. In this case, you will have to reflash the tablet.

How to navigate the Recovery menu?

Most devices allow you to navigate through the menu items using the volume buttons. The power button serves as a choice of the desired menu item. Some devices may use other keys.

If the control is touch, then we move through the points and select the desired item by pressing your finger.

How to enter Recovery if there are no volume keys on the tablet?

If your tablet does not have volume keys, try the following tips:

1. You can try to enter the desired mode by holding down the power and Home buttons at the same time. Another option is to hold down the Home key, press the power button, and release the Home key. After the splash screen appears, press the Home button again.

2. You can navigate through the menu by connecting a USB keyboard via an OTG cable or using a sensor.

Access to Recovery on Android may be needed for literally every person. This menu is used to restore the functionality of Android devices, to format memory and much more. This mode is present in almost all smartphones and tablets, so accessing it will not be difficult. Let's see what the Recovery mode is for and how to activate it.

During the operation of Android devices, various errors may occur in the operating system. Their appearance leads to a decrease in the speed of work, as well as to regular “freezes”. In the most difficult cases, smartphones and tablets lose their functionality - when turned on, the name of the phone or the Android logo (green robot) appears on the screen, but no further loading is observed. In order to restore the device to working capacity, you need to perform a master reset or clear the cache.

A general reset is also performed through the user menu. If the operating system does not load, we will not be able to get to the desired function. In this case, you need to go into Recovery Mode and perform a hard reset using the "Wipe data / factory reset" item. All data will be deleted from the device, after which it will be able to boot - then you need to perform the standard initial setup from scratch.

If the smartphone "hangs" tightly, but you do not want to lose valuable data, you can do it differently - delete the cache. In some cases, this method gives excellent results, allowing you to restore the functionality of the Android operating system. Android System Recovery also has other features:

Depending on the smartphone / tablet model, there may be some other functions.

If you do not know what this or that function is intended for in the Recovery Android menu, do not try to choose them at random - this can lead to the complete deletion of all data and other not very pleasant consequences.

In some models of phones and tablets, there is a flashing start point here. You should not try to reflash Android devices on your own without having the appropriate experience for this. If you got into the menu completely by accident and want to exit from here without unpleasant consequences, select the “reboot system now” item with the volume control buttons and press the power key - the reboot will start in normal mode (without data loss).

In order to activate Recovery Mode on Android, you need to know the name and brand of your phone. If you don't remember the name of your original handset, find the box or look under the battery for the information you need. Next, we are looking for a key combination to enter Recovery Mode on specialized forums or in search engines. Here are the most common keyboard shortcuts:

• For Samsung phones - power key, volume up key and home key (center key);
• For LG phones - power key and volume down key;
• For Nexus phones - the power key and the volume down key, then select the desired item;
• For Motorola and Lenovo, the power key, volume up key, and home key;
• For Sony, press the power button and wait for a double vibration, then move your finger to the volume up button.

Please note that sometimes these combinations do not work. If you can't enter Recovery on Android, look for the key combination for your phone model.

Also, the ADB Run program is used to enter Recovery Mode. But you can use it only when the smartphone is functional, and you have the opportunity to enable " USB debugging". If all else fails, it means that your phone does not have Recovery Mode, and you need to install it separately - it is best to entrust this procedure to experienced users.

Recovery installation instructions are posted on dedicated forums dedicated to mobile devices. Please note that such interventions often void the warranty.

Everyone who takes the first steps in learning the procedure for flashing Android devices initially pays attention to the most common way to carry out the process - flashing through recovery. Android Recovery is a recovery environment that almost all users of Android devices have access to, regardless of the type and model of the latter. Therefore, the method of flashing through recovery can be considered as the most easy way upgrade, change, restore or completely replace software device.

Almost every device running the Android OS is equipped by the manufacturer with a special recovery environment that provides to some extent, including ordinary users, the ability to manipulate internal memory device, or rather, its sections.

It should be noted that the list of operations that are available through the "native" recovery installed in the device by the manufacturer is very limited. As for the firmware, only official firmware and / or their updates can be installed.

In some cases, through the factory recovery, you can install a modified recovery environment (custom recovery), which in turn will expand the possibilities of working with firmware.

At the same time, it is quite possible to perform the main actions for restoring performance and updating software through factory recovery. For installation official firmware or updates distributed in the format *.zip, perform the following steps.

How to flash a device through a modified recovery

Modified (custom) recovery environments have a much wider list of options for working with Android devices. One of the first to appear, and today a very common solution, is the recovery from the ClockworkMod team -.

Installing CWM Recovery

Insofar as CWM recovery, is an unofficial solution, you will need to install a custom recovery environment on your device before using it.

• For Samsung devices, in most cases, the application is used.
• For devices built on the MTK hardware platform, the application is used.
• The most universal way, but at the same time the most dangerous and complex, is flashing the recovery through . The steps to install the recovery in this way are described in detail at the link:

Firmware via CWM

Using the modified recovery environment, you can flash not only official updates, but also custom firmware, as well as various system components represented by cracks, add-ons, improvements, kernels, radio, etc.

It is worth noting that there are a large number of versions of CWM Recovery, so after logging in on various devices, you can see a slightly different interface - background, design, touch controls, etc. may be present. In addition, some menu items may or may not be present.

The examples below use the most standard version of the modified CWM recovery.
At the same time, in other modifications of the environment, when flashing, items are selected that have the same names as in the instructions below, i.e. a slightly different design should not cause concern to the user.

In addition to the design, the management of CWM actions in various devices differs. Most devices use the following scheme:

• Hardware key "Volume+"— move one point up;
• Hardware key "Volume-"— move one point down;
• Hardware key "Nutrition" and/or Home- confirmation of the choice.

So firmware.

Firmware via TWRP Recovery

In addition to the solution from the developers of ClockworkMod, there are other modified recovery environments. One of the most functional solutions of this kind is. How to flash devices using TWRP is described in the article:

This is how Android devices are flashed through recovery environments. It is necessary to carefully approach the choice of recovery and the method of installing them, as well as flash only the appropriate packages received from reliable sources into the device. In this case, the process proceeds very quickly and does not cause any problems afterwards.
