I found out that this Apply update from ADB is included in the Software Developer Toolkit as one of the components of the Android SDK. Using Apply update from ADB, installing the necessary drivers, and switching the device to direct interaction with the computer via the USB interface, you get full control over it.
The Apply update from ADB console utility allows you to perform the following operations:
- Installing and uninstalling any applications, including pre-installed ones;
- Transfer files to the device and retrieve them;
- Creating operating system backups;
- Installation of new, including custom, firmware;
- Android recovery in case of damaged system files.
If you don’t yet know about the existence of a bulk folder on your smartphones, I recommend visiting the corresponding article.
Installation methods Apply update from ADB
There are several ways to use ADB. The easiest and most suitable for most users will be to install the ADBKit package. It contains the utility itself and dynamically linked libraries necessary for its interaction with the Windows operating system. A set of universal drivers for Android devices is installed separately. You can download the necessary files on the ADB Shell project website. The page is in English, but the Commands section contains a detailed description of control commands.
The Apply update from ADB utility is a console application, so you use the Windows command line to work with it. The recommended installation location for the Android Debug Bridge package is the root directory. The folder into which ADBKit is unpacked must not contain Cyrillic characters. All these recommendations ultimately simplify the user's work on the command line, minimizing possible errors when entering control commands by shortening the path to files.
To work in console mode, an Android device must be switched to “USB debugging” mode. After connecting the cable to the computer, select the “Charging only” option. This way you prepare the device to interact with the computer. I hope you understand what Apply update from ADB is. The sequence of the described actions is well shown in this video.
In it you will learn how to install and run the utility in the Windows Management Console. Additionally, it provides the syntax of the main commands required when flashing the device. The work of the Apply update from ADB utility with an Android smartphone, after switching to the console interaction mode, is clearly shown in the following material.
For more advanced users, we can recommend installing the Software Development Kit designed for Android developers. The SDK receives regular updates necessary to create applications that support new devices. Thanks to this, the set of drivers for your Android devices will always be kept up to date. It is best to download the Development Kit from the official page, without confusing it with the full set of Android Studio utilities.
Finally
What is Apply update from ADB? The variety of device models running Android OS and a modified version of Linux does not allow us to provide universal recommendations for setting them up. This material is intended to point you in the right direction of your search and provide the basics of using the Android Debug Bridge toolkit. Using these recommendations, you can connect any mobile device to your computer and perform actions with it that are not available through the manufacturers’ official utilities.

Mobile devices have already become quite an integral part of our lives. Now a person cannot imagine existence without a smartphone or tablet. Devices based on the Android operating system are extremely popular. This OS was developed by Google, and now its market share is incredibly high. Apple's iOS and Windows Phone have a negligible presence in mobile markets compared to Android. However, like all technology, devices on this platform tend to glitch. Various system failures are a hallmark of any operating system. No matter how advanced it may be. Very often devices have to be reflashed. But not everyone knows that it is possible to do without such radical measures. After all, any Android gadget has Android System Recovery 3e. How to use it and what is it even? This is what we will talk about.
What kind of animal is this?
What does Android System Recovery 3e mean? This is a kind of BIOS of a mobile device. Any operating system has its own BIOS - a basic input/output system that can work even if the main OS is damaged. Sometimes the BIOS is not similar to the standard one (as, for example, in Android devices). It is used to restore the functionality of a smartphone or tablet, apply critical updates or reset to factory settings. The Android System Recovery 3e menu has many items that correspond to one or another action. But the trouble is that the names are written in English. Therefore, many people do not even know how to use recovery correctly.
That is why this article was written. Android System Recovery, the instructions for which are absolutely necessary, is a powerful tool for setting up and resuscitating a smartphone. You need to know everything about how to use this recovery in order not to waste money on specialists. Doing everything yourself is much easier and cheaper. We will analyze each item in the recovery menu and tell you everything we can about it. So let's begin.
How to enter recovery?
This depends on the specific device model. In some devices you need to hold down the power button and the "Volume +" key. But sometimes there are smartphones for which this is not enough. Older models with a mechanical Home button require pressing this button as well. Some devices require you to simultaneously press the power and volume buttons. There are also those who must hold down the power key and both volume buttons. This applies only to original devices from well-known manufacturers.
But there are also frankly “Chinese” gadgets with an incomprehensible operating system and “crooked” translation. Standard methods of logging into recovery may not work in these cases. There are several options here. First: study the smartphone documentation (if available) and find the key combination you are looking for. But this option is not suitable for everyone. Most of these devices either have no documents at all, or the documents do not contain Russian at all. The second option: find the desired combination by pressing all the buttons one by one. Now let's move on to the Android System Recovery 3e menu items.
Reboot system now
This menu item performs a complete reboot of the device. After selecting this option, the smartphone will load the standard Android operating system without any changes. Typically, this item is used after completing all manipulations in recovery. Or if you loaded into this mode by accident. Although it is unknown how this can be done accidentally. Be that as it may, Android System Recovery 3e, the instruction manual for which is simply vital for the user, has such a clause. And we have to take this into account.
The menu item should be used last. That is, when all operations are completed, all components are updated, factory settings are reset and firmware is installed. This is the essence of a reboot: to allow the device to apply all the changes made. True, after some of them the smartphone may not boot at all. But that's a completely different story.
Apply Update from External Storage
This menu item allows you to apply the update that is located on the memory card. By the way, new firmware is also installed through this point if the main OS does not boot. There are several sub-items in this Android System Recovery 3e menu. How to flash a new OS? To do this, you need to go to this menu and select the Choose ZIP from SD Card item if the firmware is in ZIP format. If this is just an update file, then you should select Apply Update From SD Card. This is how any device is flashed using recovery. Simply copy the firmware file to the root of the memory card, go into recovery and select the desired item.
This paragraph has other subparagraphs that apply in non-standard situations. It is possible to check the MDSUM of the firmware file. This option checks the file for integrity and if something is wrong, it immediately issues a warning. You can also check the firmware file for compatibility with the device. These are the informational options of Android System Recovery 3e. Instructions as such are not required for them. If there are errors, then you do not need to install this firmware. That's the whole story.
Wipe Data. Factory Reset
This is a very important point. This option can restore the functionality of the device without any firmware. This tool resets the gadget's operating system to factory settings. Naturally, everything that was on the smartphone will be deleted: applications, photos, music. In general, everything that was in the internal memory of the phone. Android System Recovery 3e, the operating instructions for which are discussed here, was created precisely in order to revive the device without serious intervention in the firmware. And this option allows you to perform this operation.
This function is also used before installing any firmware. It is necessary to reset the phone to factory settings before flashing the firmware. Otherwise, the new operating system will be unstable. But that's not the worst. If you do not return to the factory settings, the firmware may not be installed at all, and then the user will receive a completely “dead” smartphone. There are no instructions in Russian, but the one that is there clearly states that it is imperative to use the Wipe Data & Factory Reset item before each firmware update of the device.
Wipe Cache Partition
Another useful command in Android System Recovery 3e. The recovery instructions say that you need to use this option in tandem with Wipe Data. If the previous item clears the internal memory of the device, then this one clears its cache. Namely, this is where the working application files are stored. Of course, if this is not done before installing the firmware, then nothing bad will happen. It’s just that in the future, when installing new programs, the device’s cache will grow to incredible sizes. As a result, the smartphone will work very slowly. But this is not so scary, since there are many programs for clearing the Android OS cache. And they work great.
It is also recommended to select this function after a factory reset has been done. This will help the smartphone become even “cleaner,” which will have a positive effect on the performance of the operating system. The instructions in Russian for Android System Recovery 3e recommend performing this procedure after the reset. Before rebooting the device. Then everything will be as it should be.
Wipe Battery Stats
This feature helps you refresh your device's battery. After clicking on this item, the battery cache begins to be cleared, into which the current state of the battery, its nominal capacity and other necessary parameters are recorded. By resetting the battery usage statistics, you can slightly extend its life. And the new firmware will work more adequately with the battery. For some reason, many Android “gurus” are dismissive of this option. But in fact it is very useful. However, it is not recommended to use it too often. Only before flashing the device.
Mounts. Storage
Here are the controls for the internal and external memory of the smartphone. This item allows you to clear a memory card or built-in memory, format it, or attach it as a drive directly from recovery. This section can be used if you forgot to transfer the firmware file to the memory card, and there is no desire to reboot your smartphone into the operating system. In order to mount the device's memory card as a drive, you need to select Mount USB Storage. As soon as the connection is established, the computer itself will install the necessary drivers for operation.
Once the connection is established, you can do whatever you want with the memory card: format, clear, copy the necessary files, and so on. In order to unmount the flash drive, you should select the Umount USB Storage item on the smartphone screen in recovery. After this, you can move on to other recovery points and carry out further resuscitation of the device on your own.
Recovery errors
Sometimes there is such a common error in Android System Recovery 3e as canceling the installation of the firmware or package. It can occur for several reasons: the firmware file is damaged, incorrect information in the binary file, or the firmware simply does not suit this device. But there is another option: before flashing the firmware, the device was not reset to factory settings. It’s good that they can be easily fixed in the same recovery. There are several ways to do this.
So, if the error occurs due to a broken firmware file, then you should download it, connect your smartphone to the computer, go to the Mount & Storage menu item and select Mount USB Storage. After this, you can copy the firmware again to the root of the memory card. If you forgot to “wipe”, then there is nothing easier than moving a few levels higher and selecting the appropriate menu item. But the Android System Recovery 3e error “No command” is very rare. It only appears when the user tries to install an update via ADB. Usually this method doesn't work. As a result, this error appears. So there is no point in using this method. Nothing will work anyway.
Conclusion
So, let's summarize. We tried to describe the capabilities of Android System Recovery 3e. The instructions that resulted from this attempt will help novice users of the Android operating system learn how to restore the functionality of their smartphone with their own hands. Which will ultimately lead to broadening your horizons and saving a lot of money.

Hello, gentlemen. Most people do not know their new devices well, they ask “How to get ROOT?”, “How to change OS” and so on. And to avoid such frequent questions, I will talk about various secrets about this popular mobile operating system - Android.
This time we will start with the most important thing - ClockWork MOD Recovery. Why is he and what is he hiding? We will learn about this further...
In general, CWM is like a kind of BIOS (more understandable for PC users), which helps us fine-tune an Android device. Thanks to it, we can install different patches, firmware and mods. CWM itself is located in the system memory of the smartphone, but first it must be installed. You can find details about installation for your device on this website, or download Rom Manager from Google Play (Requires Root) Basically, each device has a native Recovery. They are of different types - 1e, 2e, 3e. These native Recovery are limited in many functions than CWM.
Now let's move on to CWM itself. It comes in different versions for each device. For example, I now have version 6 of CWM. The menu may differ for some, but in general it is the same.
- clearing Dalvik cache. Needed when the device freezes or when installing a mod.Report error- saves all errors in a special file error.log
Key test- test hard keys. When you press a key, its code is displayed on the screen
Show log- saves all your actions in a special recovery.log file
Fix permission- fixes all permissions in rw-r-r in the /system directory
Partition sdcard - mounts partitions such as ext3, ext4 and creates a SWAP swap file
How to get into Recovery? Each model has different methods, but I’ll tell you one universal one. When you turn on the device and see the manufacturer’s logo, quickly press the “Volume -” key
Be careful when playing with CWM, and make backups in every possible way. Good luck on your adventures!
Recovery Mode is a special device boot mode that allows you to reset to factory settings, backups and other system actions.
Most often it is used for when there is no access to standard system settings. The procedure for logging into 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 button”. Control 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 look at them in more detail.
Stock
The stock Recovery Mode comes with the device initially and does not differ in particular functionality. In most cases, it contains the following items:
In many smartphones running Android 7.0 Nougat, the following functions have appeared in the Recovery menu:
- Reboot to bootloader (direct loading of the mobile operating system to gain access to recovery mode and start normal operating mode of the OS).
- (checking the signatures of all root files and their integrity).
- Mount / System (mounting the system and its partitions).
- View Recovery Logs.
- Run Graphics Test.
- Power Off (turning off the device).
Custom
Custom recovery includes a much larger number of functions. 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, return 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.
