When a user wants to update the firmware of his Android device, he encounters the “Apply update from adb” option in the Recovery menu. We will tell you what it is and what ADB is responsible for on Android.
Many Android users I'm interested in the question - how can I modify the existing firmware and thereby get a newer one? The Android debug bridge, which has the abbreviation A.D.B.. Using this option, you can control any device running Android system, unless the manufacturer has blocked access to this functionality. It is worth saying that the operating principle of ADB has a client-server basis.
Apply update from ADB(translated as - Apply Android Debug Bridge updates) - a phone control function used when updating, restoring or customizing the system firmware.
Apply update from ADB function in the menu Phone Recovery
Update using ADB Sideload
The debug bridge has an excellent command in its arsenal - this ADB Sideload, which allows you to update outdated firmware or restore the device (this is if it does not boot).
Updating your Android device is affordable ZIP archive and menu Recovery(if it is missing, you can use the bootloader). It is worth noting that there is a command similar to ADB Sideload - this fastboot -w update. But it does not work in all cases.
- Requires a PC ( personal computer) or laptop (with operating Windows systems 8/8.1 may have problems).
- An Android driver is required.
- Software ADB RUN.
- Availability of original and working USB cable.
- The device must be charged more than 40 percent.
- You must have an archive in ZIP format with the necessary update.
Need to enable USB debugging on the device.
Update download algorithm
- First of all you need to download ZIP archive with an update for your gadget on your personal computer.
- The second step is connection USB cable for connecting a smartphone or tablet with a computer.
- At this step, you need to boot into recovery mode on your Android device (English name - recovery mode).
- After switching to recovery mode, you must select the “Apply update from ADB” command.
- The last action is the transition to command line and execution ADB commands Sideload ( adb sideload<путь к файлу, название_файла>.zip).
I hope you understand what the Apply update from ADB function means in the Recovery menu and apply the described algorithms when updating or restoring Android.
Every tablet or phone based on Android OS is equipped with an environment Recovery Mode. It refers to the system part of the mobile operating system and allows you to perform specific procedures on the device, which regular menu are unavailable. Let's look at what it is Android Data Recovery, how to enter this mode and how to work with it.
Purpose of the recovery area
Recovery Environment Recovery Mode is an indispensable tool for developers and engineers dealing with programming or customizing the Android OS. However, it is often resorted to regular users mobile devices.
Considering what Recovery mode is, it is necessary to note its main capabilities:
- Reset the gadget to factory settings ( Hard Reset), when with standard menu this cannot be done;
- Installation of custom firmware;
- Activation of Superuser rights;
- Creating a system backup with all user data and settings;
- Restoring Android using a previously mounted backup;
- Allocation to external map micro memory SD system partitions;
- for working with the ADB debug bridge, etc.
It should be noted that you cannot do without Recovery on Android if you cannot enter the graphical menu of the operating system, as well as if your smartphone or tablet turns into “”.
How to enter the Recovery environment
Transferring a mobile device to Recovery mode can be done in several ways:
- Using a combination of mechanical keys;
- Via the ADB debug bridge;
- Through special software, which is installed directly on the phone.
In the first case, to enter Recovery Mode, use certain combination Power buttons, Home (if available) and sound control rockers. At the same time, different manufacturers this combination may vary. Thus, in almost all Nexus series smartphones, the resuscitation area is loaded using the Power + Volume Down keys. For Samsung, the current set is “Power” + “Home” + volume rocker sandwiched in the middle. The above steps are performed with the device turned off.
If you cannot find the required combination, you can open Recovery on Android using the ADB debugging bridge or its automated version ADB Run:
You can also get into recovery mode using additional software installed directly on the mobile device. One such application is Quick Boot. It is enough to install it from Play Market and after launch, click on the appropriate button. 
How to work in the recovery environment Recovery Mode
There is no Recovery in the area GUI, to which all owners of smartphones and tablets running Android OS are accustomed. Yes and touch control Doesn't work there either. Therefore, it would be a good idea to consider how to use Android mode Data Recovery.
The main window of standard Recovery is a list of functions. Moving between menu items is done using the mechanical Volume Up/Volume Down keys, and selecting an item is done with the Power button. 
Once in stock Recovery Mode, the following tools will be available to you:
- Reboot system now. Used to reboot mobile device and entering the Android GUI.
- Wipe data/factory reset. Cleanses internal memory device from installed applications, notes, contacts, etc. At the same time, personal photos, videos and documents will remain intact. This function allows you to get rid of various operating system failures.
- Wipe cache partition. Removes all information from system cache. Used when incorrect operation installed software, and also before flashing the gadget’s firmware.
- Backup and restore. Creates system backup and restores the phone using previously created points.
- Mounts and storage. Allows you to clean one of the system partitions.
- Advanced. Opens additional features Recovery (restart this mode, erasing dalvik cache, etc.).
You should work very carefully in the Recovery recovery environment, since all actions performed are irreversible and can lead not only to permanent deletion of all user information, but also to transform Android into “”.
Using custom Recovery
Stock recovery mode has several disabilities, which in some cases are simply not enough. So, you won’t be able to reflash your smartphone using it or install the required application from a memory card. Therefore, advanced users replace standard Recovery to a custom one (CWM or TWRP), which has more advanced functionality.
As an example, let's look at the installation procedure and subsequent use of ClockWorkMod (CWM) Recovery:
Will begin Android installation CWM Data Recovery. This process won't take much time. After it is completed, you can enter the custom recovery environment using the same keys that were used to load the stock Recovery.
