Android is a popular operating system for smartphones and tablets. Like any other OS, it requires cleaning the memory, resetting, and restoring some applications and items. The operating system of the phone already has a program for performing these functions. It's about the Android System Recovery 3e menu. The instructions contain a description of it, as well as information on how to use the application.
Recovery Android menu (translation: Android recovery) - BIOS (BIOS) of a smartphone or tablet. That is, this is a basic I / O system that works even if the main OS is damaged, and therefore it is very important to master the use of Recovery. Even if other applications are installed to clear the memory of a mobile device, as well as restore it, if the basic elements of the system are damaged, you can only restore the device using this function.
The BIOS menu includes a huge number of items and makes it possible to both update the smartphone and fix errors in the operation of the device, reset the settings to factory settings, etc. However, for many users, the problem will be that the interface of the Recovery system is completely in English. Therefore it is important to know, how to enable BIOS, and also study the instructions on how to use System Recovery.
How to enable BIOS mode
The first difficulty that many users will face is how to enter BIOS mode. On most devices, for example, Samsung, Lenovo, Nokia, you need to enter Recovery Mode by simultaneously pressing and holding the power and volume keys of the device.
In order to enter BIOS mode, you must turn off your smartphone or tablet, then press and hold the indicated buttons. On some devices, you can go to the Recovery menu only when the device is connected to a charger. After pressing the keys, the logo of the manufacturer of the device should appear on the screen. When this happens, you can release the buttons. After a few seconds, the BIOS menu should appear.
As for the buttons for turning on the mode, it is mainly necessary to hold down the volume up key, but on some devices, either the volume down or both buttons can be used. In older models of smartphones, sometimes you need to hold down the power key and the Home button.
If none of the proposed options worked, then you need to study the instructions for the device. Usually, non-standard ways to enable BIOS mode are found only in unpopular smartphone models, as well as in Chinese-made devices. All modern devices from well-known manufacturers are manufactured according to certain standards, and therefore the method of turning on and working with System Recovery on them will be similar.
Main functions
Through the BIOS menu, you can perform many actions with the device. Usually the Android System Recovery menu consists of 9 sections, including sub-items. Let's consider the main ones with translation into Russian.
Reboot now is one of the main commands that allows you to reboot the device without additional steps. This item is not divided into subsections. By executing the command, the smartphone will reboot without any changes in the system operation.
Install from SD-card is one of the large sections of the BIOS menu, which includes 5 commands. 
The main task is CWM (Clockwork Mod) - installation of the necessary packages with an arbitrary file name. The main functions of CWM:
- installation of custom (official and unofficial) firmware and kernels;
- additions and correction of errors in the operation of the OS, installation of factory updates;
- creating a full-fledged backup copy of the current firmware of the device;
- system recovery from a previous backup.
In this section of the Android menu in Russian, you can see several commands. Each of them allows you to perform one of the above functions:
- choose zip from SD-card - install the package from the memory card;
- check md5sum of a file - check the hash sums of the file;
- apply / sdcard / update.zip - installation of the CWM package to the root update folder. zip from the memory card directory;
- toggle sigrature verification - verification of the Clockwork Mod package signature to verify the authenticity of its contents, this function is disabled by default;
- toggle sclipt assert - verification of the script's compliance with the device's settings, must be performed before flashing the device.
Toggle usb storage - this mode allows you to connect a memory card to a smartphone to use the device as a USB storage for a PC or laptop.
Wipe (Format) - section dedicated to Wipe. You can either completely reset the data, or delete only some files, for example, the cache, format a specific section of the device.
Let's consider the main options of this function:
- Wipe data (may also be called factory reset) - an option that allows you to reset the smartphone in the based (basic) factory settings;
- Wipe cashe - a function for formatting a section with a cache;
- Format system is an option that allows you to completely remove the system, that is, all system files are formatted and the installed firmware is reset.
Backup (restore) - a section where you can back up the firmware and restore the system. The backup function is used to create backup copies of the main software sections. Selecting the restore option will restore the system from previously created backups. Sections Advanced Restore and Advanced Backup are designed for more advanced users, as they allow you to selectively back up and restore the main software partitions.
EXT3 - 4EXT - a section that allows you to convert the system, as well as its individual elements from EXT3 to EXT 4 and vice versa.
Mouts | strage is a function for mounting and unmounting system partitions. Thanks to this option, you can perform operations with the following sections: cache, data, sdcard, and also system.
Advanced - a section with advanced settings, which includes various unclassified functions. The Advanced option includes the following items:
| Function |
Description |
| File System Check | a function that allows you to check all system files |
| Print Partition Info | system analytics and displaying view logs on the screen |
| Copy recovery. log to sdcard | option to copy the recovery log and write it |
| Fix Permission | a function that allows you to change the rights to files in the / data section |
| Partition SD Card | option to form ext and ext2 partitions on the memory card. Here you can either create partitions (for this you need to enter Remove all partitions and start from scratch), or go back to the main Recovery menu without saving changes (for this you need to go to the No - save my fat32 partition section). |
Power menu - literally translated as "power menu". Here you can perform the following operations: completely turn off the device (power off), reboot the smartphone (reboot), reboot in the Recovery mode (reboot recovery).
All these functions are present in the Recovery section of almost every device. Depending on the smartphone or tablet model, the functionality of System Recovery may expand or contract.
Step by step instructions
Let's take a look at the main features of Android System Recovery 3e:
- how to flash a mobile device,
- how to reset the settings,
- clear part or all of the memory of the device,
- make a backup.
Basically, the Recovery mode is used in extreme cases. For example, when a smartphone needs to be flashed after some damage to the internal files of the system, which makes it impossible to turn on the device. Here is a short instruction in Russian Android System Recovery 3e.
If you need to reflash the device, then you need to go to the Install from SD-card section (may also be called Apply Update from External Storage). Here you can install the firmware from the memory card. To do this, you need to enter the Choose Zip from SD-card sub-item, if the new system is saved in the archive, or select the firmware image using the Apply Update from SD-card item.
If the firmware is being installed for the first time or if you are not sure about the compatibility of the new system version with the device, then it is recommended to use the toggle sclipt assert option before installation. It will allow you to verify the serviceability, authenticity and compatibility of the firmware and the smartphone.
After updating the system, you need to use the Reboot now function, which will reboot the smartphone. Before restarting, make sure that all the necessary operations have been done, since after resetting the version will be updated and all changes will take effect. With the help of Reboot now, you can also reboot if the user got into recovery mode by accident and you need to make a backup (return to the main menu of the system).
Additional features
Another important option for recovery mode is Wipe Data. Thanks to this function, you can restore the system without using firmware and resetting system settings. The option works on the principle of resetting the phone settings to factory settings. This will remove all files (images, video and audio files, downloads, etc.) from the phone.
It is also necessary to use the Wipe Data function before flashing the device, since before reinstalling the system, all settings of any device must be reset to their original values. If this is not done, then after the firmware the smartphone may not turn on at all.
Wipe Cache Partition is an equally useful function of the Recovery mode that allows you to clear the system cache. It will help to remove all the trash from the phone's memory, which will speed up the operation of the device.
After all the necessary actions have been performed, you can reboot the system using the Reboot Now function described above. With the correct flashing, the Android updates will take effect.
As with any operating system, Android has a special boot mode where the device turns on but the system itself does not boot. This mode is called Recovery Mode, or in Russian, the recovery mode. This mode is available in any Android device and allows you to reset the parameters, change the firmware, restore the firmware from a backup, or just in case of a freeze. It is noteworthy that, unlike root-rights, the use of Recovery Mode is not dangerous, therefore it 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 item in its menu is responsible for.
Recovery Mode provides access to system functions of the device
Ways to enter Recovery mode
On the device itself
The standard way. The principle of entering Recovery Mode is the same for all devices - when you turn it on, you need to hold down a few buttons. Most often this is the volume up, but the following options can also be found:
- Samsung - turn on + volume up + "Home".
- LG - turn on + volume down.
- Google Nexus, HTC - turn on + volume down, then tap Recovery.
- Certain Lenovo, Motorola models - turn on + volume up + "Home".
- Sony - power button, after double vibration, hold down the volume up.
If for some reason you cannot enter Recovery Mode by standard means, try to clarify in the instructions. The listed combinations work in almost all cases and will work both for entering the standard recovery menu and for the custom one. In addition, it can be started 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 allow superuser rights and enter two commands: first su, and then reboot recovery. The device will reboot.
Via computer
A prerequisite is the enabled debugging mode via USB (Settings - For Developers - Debugging via USB, or select the appropriate item when connected to a PC). Therefore, if this mode was previously disabled, the tablet does not start, it will not work 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.
- Connect your device to your computer.
- Start the ADB Run program.
- In the program menu, press 4 in sequence and then 3.
The device will reboot into Recovery Mode. You can follow the procedures you want.
How to use Recovery Mode
As we already said, there is both a standard recovery and a custom one. Many experienced users argue that the capabilities of the former are rather scarce, so it's better to install an unofficial one. We will talk about them a little later, but now we will analyze which items of the Recovery Mode menu you can find on your device.
Install zip from sdcard - installation of the archive with updates saved to the memory card. Through this menu, root rights are obtained and the firmware is performed.
Wipe data / factory reset - erase data / factory reset - complete cleaning of the system partition, reset all settings to their original state. All applications and settings will be removed, but the media will remain intact. Used for critical errors, system crashes, or when a new firmware is running. Especially effective in cases where the device does not turn on.
Wipe cache partition - clearing the system cache - the system partition where temporary files and all program settings are stored. It is advised to do it when the firmware is changing.
Backup and restore - system backup and restoration from previously created backups.
Mounts and storage - for correct operation, all system partitions must be properly mounted and connected. Often, this procedure is performed automatically, but sometimes you have to fix something manually. You can also clear one of the sections. We advise you to use this method only in case of a specific need, otherwise the file system will not boot and the tablet will not work.
Advanced - additional settings, including restarting Recovery Mode, clearing the dalvik cache, resetting system application permissions. Most often used by professional programmers.
Management, unless otherwise specified, is carried out through (going through the list) and power supply (selecting a menu item). In some cases, selection occurs with volume up, and scrolling - with volume down. In any case, the system necessarily indicates how exactly to manage the menu sections. There are developments with touch control.
Informal 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, get root rights, reset settings to factory defaults, or restore a backup copy.
CWM looks very much like a standard one, only with a slightly different arrangement of menu items. Navigation through the menu is carried out using the volume buttons, and the choice is through the power button. There is a version with touch control. Well, TWRP has an unusual tiled interface and is controlled via a touch screen. Navigation through the menu is done by pressing the display, and you need to confirm the action with a swipe. Some Android devices have one of these recovery installed either by default or standard. Installing and downloading custom recovery may differ depending on the model, so look for information in the sections about your tablet model on specialized forums.
Conclusion
How to enter Recovery? Many Android upgrade and firmware instructions require you to perform actions from the Recovery menu. What this mode is and what it is for, you will learn from this article. What is Recovery? Recovery is a special Android boot mode in which:
- perform a full Android data reset
- flashing a smartphone
- get Root rights
How to enter Recovery? The Recovery menu is usually found in all smartphones and tablets from Samsung, but absent in other brands of Android smartphones, but it can be easily added by flashing this section to your Android device.
If the Android smartphone has a Recovery menu and it has not been changed, then it is called STOCK, if there was no or third-party Recovery menu installed, it will be called CUSTOM.
There are basically two types of custom recovery CWM and TWRP, less common 4ext,Philz CWM, (different development teams).

Good day! Today our story will be about ClockworkMod. As usual, we will tell you what it is and why it is needed. In short, ClockworkMod is a third-party recovery, which is designed to install custom patches and firmware on android devices.
Let's look at the functions of CWM in more detail, as well as get acquainted with the method of its installation and the list of supported devices. And so, let's talk about CWM in detail. What is it for and what functions does it perform? CWM, or in other words, ClockworkMod is a kind of program that is stored in a special section of the phone memory, inaccessible without extended rights and designed to install a variety of user and original firmware, various patches that directly affect the system part of your device on android. However, the functionality of the program does not end there. In addition to installation, the program has many diverse functions, such as wipe data (clearing user data or resetting data), wipe cache (clearing the cache), etc. There are a lot of functions and sometimes they are very helpful in restoring your phone. Let's take a closer look at the functionality of a particular ClockworkMod, using screenshots from the program itself:
Thus, the program menu itself looks like on the Samsung Galaxy SIII phone. As you can see, there are 7 points. Let's consider them in more detail:
- Reboot system now
- Install zip from sdcard
- Wipe data / factory reset
- Wipe cache partition
- Backup and restore
- Mounts and storage
- Advanced
First point in the menu just reboots your phone.
Second point the menu has the following settings:
- Choose zip from sdcard (choose zip from sd card)
- Apply /sdcard/update.zip (apply automatically /sdcard/update.zip)
- Toggle signature verification
- Toggle script asserts
The first item in the current menu allows us to select the required installation file in * .zip format. When you click on the item, the file manager opens.
The next item allows you to automatically select the required update if it has the correct name (update.zip) and is located in the root directory. The last two points are unnecessary for the average user. They are needed in order to interact with various scripts that are usually used when creating firmware installation files.
Third point in the main menu allows you to perform a factory reset. This will destroy all your apps, reset all settings, and return your phone to its original state. However, user information on the memory card and in the phone memory will not be affected.
Fourth point in the main menu allows you to clear the cache. This is necessary in the event that you have started some "glitches" in the applications.
Fifth point extremely useful, with the help of it you can restore your system at the time of creating a backup. We will consider it separately in a separate article:
Sixth point the most voluminous in the main menu. By clicking on it you get to the following menu:
- Mount / efs (mount the efs directory)
- Unmounts / cache (unmounting the cache directory)
- Mount / system (mount the system directory)
- Unmount / data (unmount the data directory)
- Mount / preload (mount the preload directory)
- Mount / extsdcard (mount an external sd card)
- Format / cache (formatting the cache directory)
- Format / system (formatting the system directory)
- Format / data (formatting the data directory)
- Format / preload (formatting the preload directory)
- Format / extsdcard (formatting external sd card)
It makes no sense to describe all these points, their purpose is already clear. Let's move on to the last item in the main menu.
Seventh point in the main menu contains some additional settings that are not included in any section. Here's a screenshot from that section:
The first item allows you to reboot the recovery without completely rebooting the phone. The second and third points allow you to clear the dalwick cache and battery statistics, respectively. With the fourth step, you can send an error message to cwm. Key test will allow you to test hard keys. When you click them, the program will display their code. With the help of the next item, you can read the entire log of your operations. The following items in the menu are not recommended for ordinary users, as you can make a "brick" out of your phone.
And so, these are all the settings that ClockworkMod contains. There is one unanswered question, how to install it? To do this, you need to go to the official website: www.clockworkmod.com or go straight to the play market. After you download, install and open this application, you will see the following screen:
Just click on the "Install ClockworkMod" item and the whole process will automatically flash in your eyes. Now it remains to find out exactly how CWM is turned on on your phone. Check this information with the manufacturer or on the appropriate forums.
The most important thing in installing CWM is not to "ruin" your mobile phone. To do this, you need to be sure that the kernel, firmware and model of your android smartphone are fully compatible with the program. To check compatibility, visit the xda-developers forum, your device section.
Good luck in your endeavors!
Hello everyone. We study the Android smartphone further, today we will think about what apply update from ADB is. So, after digging around on the Internet, I came to the conclusion that apply update from ADB is an item in the Android system recovery menu. But what does this item do? I went to look ... So the apply update from ADB item is needed in order to install the firmware
Well, what is the translation into Russian, here is how apply update from ADB is translated? Hmm, let's explain! The first word “apply” is translated as “apply” or “use”. I think the word update is understandable, this is the update itself, in our case the firmware. Well, from ADB is like from ADB. In short, the item apply update from ADB is translated as how to apply an update from ADB, well, something like this
By the way, I found a picture of how this item looks in the menu:
So look what else I learned about apply update from ADB. There is such a command as adb sideload, well, this command is for updating the firmware. It works like this, you enter Recovery mode on your smartphone, then select apply update from ADB with the volume button, confirm with the power button and then enter the following command:
adb sideload update.zip
Where update.zip is, then there you specify the name of the firmware. Well, a little clear? The Apply update from ADB item is needed to install the firmware from ADB. True, there is one incomprehensible moment, on another site I found information that this command must be entered into the command line. But where is the command line itself? On a smartphone or on a computer? This question is still incomprehensible to me.Aha, I dug up a picture, see here it seems everything is clear:
Apparently, all the same, the command must be entered on the computer! And I thought that in a smartphone ... Well that I learned, I was just very interested ..
By the way, after the command has been entered, the entire firmware process can take about 15 minutes, which is somehow too long .. When everything is over, select reboot system now with the volume button and press the power button. And the power down item is like turning off the smart, well, like this
