If errors occurred when installing the update - Status CWM

Recovery mode (aka recovery) on Android is a special hidden menu and available on any smartphone Samsung Galaxy. This great tool, which can be used to erase data, reset settings, format system partition, installing a custom kernel, new firmware and many other things that should allow you to improve your smartphone and its system.

Recovery mode can be stock or custom. Stock recovery mode (Stock Recovery Mode) is the first and original version, which is installed initially on your smartphone and is what you can work with immediately after purchase. This mode works on a stock smartphone or one already rooted, but not on a Galaxy smartphone that is flashed with custom firmware.

Custom Recovery Mode can be installed only after obtaining root rights on the smartphone. There are two most popular custom recoveries for Galaxy smartphones ClockworkMod - CWM and TWRP - Team Win Recovery Project. Both of them are very similar in their features and you can get the same features in either of them. Below you will learn how to download Samsung Galaxy smartphone in recovery mode.

How to boot a Samsung Galaxy smartphone into stock/CWM/TWRP recovery mode:

Turn off the device completely.
Press and hold the volume up buttons, Home button and the power button at the same time.
Release the buttons when the smartphone screen turns on and you will see the stock/CWM/TWRP recovery logo.

After you release the buttons, you will already see the main menu of the recovery mode. Here you can install required parameters settings or perform important actions with the system, including installing custom or other stock firmware.

To boot normally you need to go back to main screen recovery mode and select “Reboot system”.

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, so 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 menu item is responsible for.

Recovery Mode allows access to system functions devices

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 models, Motorola - power on + volume up + “Home”.
Sony - power button, after double vibration, hold down the volume up.

If for some reason you enter Recovery Mode standard means If it doesn't work, 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 installed application Terminal Emulator(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 a program ADB Run(http://cloud-androidp1.in/Android/PC/Project_Site/AdbProgramm/), cable and working device.

Connect your device to your computer.
Run ADB program Run.
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 let's 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 - complete cleaning system partition, reset all settings to original state. All apps and settings will be removed, but your media files will remain intact. Used for critical errors, system failures or when executed new firmware. Especially effective remedy in cases where the device does not turn on.

Wipe cache partition - cleaning system cache- a system section 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 in case of specific need, otherwise file system will not boot and the tablet will not work.

Advanced - additional settings, including rebooting Recovery Mode, clearing dalvik cache, resetting permissions system applications. 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 developments with touch control.

Unofficial Recovery

As mentioned above, standard Recovery Mode very often has several limited opportunities, therefore it is best to use third-party, unofficial developments. The most popular are two of them - ClockworkMod recovery(abbreviated as CWM) and TeamWin Recovery Project (abbreviated as 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 settings or restore backup copy.

CWM looks very similar to the standard one, only with a slightly different arrangement of menu items. Navigation through the menu is carried out using the volume buttons, and selection is made through the power button. There is a version with touch controls. Well, TWRP has an unusual tiled interface and is controlled via touch screen. You can navigate through the menu by pressing the display, and you need to confirm the action by swiping. Some Android devices have one of these recovery installed either by default or with the standard one. Installation and download custom recovery may differ depending on the model, so look for information in the sections about your tablet model on specialized forums.
