– Creating a complete backup of the system or its individual parts (application data, system partition, cache, settings);
– Connection via USB cable to a computer as a removable storage device;
– Restoring the previous state of the system from an earlier saved backup copy (backup);
– Editing sections on the memory card (creating, formatting, deleting);
– Ability to reset to factory settings (Wipe – data / factory reset). You can delete only part of the data instead of completely resetting it to its original state: deleting battery statistics (wipe battery stats), clearing the cache (wipe cache), erasing the dalvik-cache (wipe Dalvik-cache);
– Use as a terminal for executing commands;
– Ability to work with system files on a tablet or phone.

ClockworkMod Recovery – recovery for android devices, an alternative to the factory one, with many useful features : creating backups, restoring the system from a backup, installing firmware and much more.

Any user of a device running on the Android OS who is just beginning to delve into the essence of this operating system, visiting various forums, blogs and sites someday, but will certainly come across a rather strange and mysterious name – ClockworkMod Recovery. Most often, it is mentioned when it comes to replacing the kernel, flashing a smartphone or tablet and other “hacker” shenanigans.

Many people are probably worried about the question, what kind of ClockworkMod Recovery is, and also, what is it for and what to do with it? I will answer these very questions in this article, in the form of a complete instruction manual for ClockworkMod Recovery. In short, ClockworkMod Recovery, or as it is also called CWM, is an alternative recovery for devices running on Android OS. The ClockworkMod Recovery user manual consists of several sections: 1. Recovery. What is it? 2. What is ClockworkMod Recovery and what is it for? 3. Installing the ClockworkMod Recovery utility. 4. Launching the ClockworkMod Recovery utility. 5. Analysis of the ClockworkMod Recovery menu.

6. System recovery, as well as creating backups using CWM.
7. Main features of ClockworkMod: installation of updates, firmware, kernels and other elements on Android devices.

Recovery. What is it?

All devices running on the ANDROID OS have factory recovery, which, if necessary, can be loaded when you turn on your smartphone or tablet, using a special key combination. The factory utility, as a rule, is able to clean the system, as well as install OS updates from the file.

What is ClockworkMod Recovery and what is it for?

ClockworkMod Recovery is an order of magnitude more powerful system utility than the built-in factory one. Thanks to it, you can create full backups of the Android operating system, and also install various software and all kinds of kernels and firmware on the device, and much more that the factory recovery does not perform. ClockworkMod Recovery is installed instead of the factory menu, in a special section of the internal memory of the device.

There are seemingly hopeless situations in which ClockworkMod Recovery can help. For example, if a smartphone or tablet, for whatever reason, cannot boot, this utility will help restore the operating system, with all its applications and settings.

Below are some of the most important operations that can be done with ClockworkMod Recovery :
1) Connect to a PC via a USB cable when using the removable storage mode.
2) Install unofficial kernels and custom firmwares.
3) Carry out the installation of factory system updates, as well as various fixes and additions.
4) Restore the operation of the device using a previously created copy.
5) Work with the ADB tools by connecting your device to a PC using a USB cable.
6) Carry out the creation of a complete backup of the current firmware, as well as its parts, such as settings, applications and OS.
7) Create and edit sections on the device’s memory card.
8) Go back to factory settings (Wipe – data / factory reset), reset the wipe battery stats, clear the wipe Dalvik-cache and clear the wipe cache.

The ClockworkMod Recovery utility was developed and subsequently created by Koushik Dutta, aka Koush. For most Android devices, there are CWM versions.

Installing ClockworkMod Recovery

It can be noted that for most devices, installing the ClockworkMod Recovery utility is a fairly simple procedure. To do this, you just need to download and install the ROM Manager tools from the Market and run it. The first item on the menu will be – Install ClockworkMod. For other smartphones and tablets, there are other separate utilities which are similar to the Acer Recovery Installer used on the Acer Iconia Tab. Well, or you can install ClockworkMod Recovery on them, but only using the ADB tools, which is an integral part of the Android SDK and you can download it here .

Launching ClockworkMod Recovery

You can load your device into ClockworkMod Recovery in several ways.
1) Using the ROM Manager tools, you will need to select an item in the menu called “Load Recovery Mode”.
2) Using a specific key combination when turning on the Android device. Most often, the combination depends on the brand and model of the tablet or smartphone. But in most cases, this is a combination of pressing the volume down rocker and the power key at the same time.
3) Using the ADB tools. When configuring the connection of your device to a PC using this tools, in order to boot the device you will need to enter the “command”: adb reboot recovery.

ClockworkMod Recovery Menu Analysis

When you boot your tablet into ClockworkMod Recovery utility, first of all you will see its main menu:

ClockworkMod Recovery - installation, backups, system recovery, flashing android devices, and more. dr ..

The screenshots were taken in ClockworkMod recovery 3.0, one of the most popular and widespread. In other versions, including newer ones, the menu may change slightly, but, nevertheless, its main features , as a rule, remain unchanged.
On many devices, moving through the menu items is done using the volume rocker. And in order to select a specific item, use the power button. However, some Android devices may use other keys, for example, to return to a previous menu.

Whichever submenu you are in, in order to return to the previous menu, you can use the item +++++ Go Back +++++

Let’s move on to assigning the main menu items:
1. reboot system – directly, reboot the device.
2. apply from sdcard – without a doubt, the item that is used most often.
Thanks to it, it becomes possible to install official and custom firmwares, as well as themes, kernels and other software, which must be in the file, and you must move it to the root of the memory card. For example, in the file manager of a device running on Android OS, this is the / sdcard folder.
After you have selected this item, you will automatically be taken to the next menu, in which you must confirm your choice by clicking on Yes – Install /sdcard/

3. wipe data / factory reset – full reset of settings, cache and data. That is, after you use this item, the device will return to the state in which it was sold in the store. CWM will clean the / data and / cache partitions in the internal memory of the device. And also everything will be deleted from the system folder “.android_secure” located on the memory card, including the sd-ext partition.
4. wipe cache partition – clearing temporary data accumulated during the use of the system and various toolss, that is, clearing the / cache partition located in the internal memory. Most often this item is used before starting to install a new firmware or kernel.
5. install zip from sdcard – installs a zip file from a memory card. After you select this item, you will automatically be taken to the following submenu:

ClockworkMod Recovery - installation, backups, system recovery, flashing android devices, and more. dr ..

And its items mean this:
1) apply /sdcard/ – well, this item fully corresponds to the second item of the main menu “apply from sdcard”.
2) chooze zip from sdcard – this item is needed in order to select the .zip file on the memory card for installation.
This item is also similar to item 2 of the menu and is used to install various firmware, kernels, and other modifications. But there is still a difference in it – the installation can be done from absolutely any file with the zip extension, having any name, and located anywhere on the memory card. After selecting this item, you will see the entire list of folders and files on the device’s memory card, from which you need to select a .zip file for further installation.

3) toggle signature veritification – enable and, accordingly, disable file signature verification.
When the signature check mode is enabled (Signature check: Enabled), installation of firmware that has not been signed by the developer will become impossible. And most of the unofficial firmware, just the same without the developer’s signature.
4) toggle script assert – enable or disable the assertion script.
This item is needed for internal use in ClockworkMod Recovery, that is, you don’t need it, so it’s better not to touch it at all.
5) +++++ Go Back +++++ – well, this item, as described above, is needed in order to return to the previous CWM menu.
6) backup and restore – this item is needed when creating and restoring device backups. Also, one of the most basic points of CWM. Thanks to him, you can make a complete backup of the tablet system, including all applications along with the data that is located in the internal memory of the device. This procedure is also called “Nandroid backup”, which means “System snapshot”. This is necessary in order to return the smartphone to its previous state. It looks like this:

ClockworkMod Recovery - installation, backups, system recovery, flashing android devices, and more. dr ..

And its points mean this :
Backup – creating a backup copy of absolutely all partitions in the internal memory of the device.
The copy, after creation, will be located on the memory card. Initially, the name of the backup consists of the time and date of its creation. But it can be renamed. But it should be remembered that the name must consist of numbers and Latin letters, spaces and Russian letters are not allowed.
Restore – restoring all partitions after selecting a specific backup.
After selecting this item, you will see the entire list of available backups located on the memory card. To restore, you just need to select one of them.
Advanced Restore – this item denotes the restoration of only a specific partition from the backup that you choose.
The choice of any individual partition you wish to restore is up to you: system, cache, sd-ext, data, or boot. More details can be seen in the screenshot below:

• format sdcard – formatting the device memory card;
• format sd-ext – formatting the Linux partition on the memory card;
• mount USB storage – connecting the device to a PC, in the removable device mode.

3. Wipe Battery Stat – reset the statistics of the battery operation. This item is most often used to reset incorrect battery meter information.
4. Report Error. This item allows you to inform the developers of the ClockworkMod utility about the error. In this case, the error log is written to the device’s memory card and can be sent using the ROM Manager tools.
5. Key Test – using this item you can check the functionality of the device buttons. It works as follows: when you press a button, its code is displayed on the screen.
6. Restart adb – reboot the ADB server. This item can be used if the device stopped responding to the commands of the ADB tools, when connected to a PC, via a USB cable.
7. Partition SD Card. With this item you can create partitions on the device’s memory card. That is, you can create / sd-ext and / swap partitions on the memory card. The / sd-ext partition is needed for use by certain firmware, in case of insufficient internal memory of the device. And the / swap section is needed in order to speed up the operation of the Android device.
8. Fix Permissions. This item will help you fix the access rights to sections and files. That is, there is a return to the factory state of access rights to files and folders of the system, in the event that changes were made due to the incorrect operation of various root applications, which could lead to failures and freezes in the operation of the device.

System recovery, as well as creating backups using CWM

Well, you already know that thanks to ClockworkMod it becomes possible to create full backups of the device’s firmware. This utility creates snapshots of all the partitions that are in the internal memory of the device, as well as the “.androidsecure” folder, which is located on the memory card. Moreover, the “snapshot” is taken by the OS, along with its settings, and installed applications.

Create a backup (Nandroid Backup):
– Reboot the device to CWM recovery.
– Open the “backup & restore” item.
– Select “backup”.
– Confirm your selection by clicking on “Yes”.
– After creating copies, exit CWM using the “reboot system now” item.

After that go to the clockworkmod / backup folder. It will contain a full backup. Its name, as already mentioned, will consist of date and time, but you can give a different name to the file. Do not use Russian letters under any circumstances.

Restoring the device from a backup using CWM:
– Reboot the device to CWM recovery.
– Click on “Backup & restore”.
– Select “restore”.
– Now you need to select the required backup from the list.
– Well, confirm your choice by selecting “Yes”.

After the recovery is complete, exit CWM using the Reboot system now item.

Note :
Some individual applications from the CWM backup, SMS, as well as WiFi settings, at the same time, without touching the current firmware, you can restore using the AppExtractor application or the Titanium Backup tools .

The main features of ClockworkMod: installing updates, firmware, kernels and other elements on Android devices

All potential firmware, custom kernels and other applications and add-ons that can be installed on the device using CWM are packed in files with the zip extension.
Before installing anything on your smartphone or tablet, make a backup copy of the original firmware, in order to do everything as it was if necessary.
Make sure the device battery is fully charged and disconnect it from the PC and charger.
Copy the file that you want to flash to the root of the memory card, but never unpack it, and also make sure that its name consists only of Latin letters and numbers.
If you are interested in installing a full firmware, then do a full wipe using the “wipe data / factory reset” item.

Only after that proceed with the firmware :
– Insert the memory card into the device.
– Reboot your device to CWM.
– Select “install zip from sdcard”.
– Open the “choose zip from sdcard” item.
– In the window that opens, find the file. It should be at the bottom, right after the list of folders, if there are any.
– Confirm your choice using “Yes”.
– After completing the firmware, return to the previous menu using the “+++++ Go Back +++++” item.

It is also recommended to wipe cach and dalvik cache after flashing the zip files.
