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 operating system"Android". This OS was developed by Google, and now its market share is incredibly high. iOS from Apple and Windows Phone an insignificant percentage of 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, every 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 it mean Android System Recovery 3e? This is a kind of BIOS mobile device. Any operating system has its own BIOS - basic system I/O 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 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?

It depends specific model devices. 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. Old models with mechanical button"Home" requires 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 only applies original devices from well-known manufacturers.

But there are also frankly “Chinese” gadgets with an incomprehensible operating system and “crooked” translation. Standard Methods Logging into recovery may not work in these cases. There are several options here. First: study the smartphone documentation (if available) and find the desired key combination. But this one option will do not everyone. Most of these devices either have no documents at all, or the documents do not contain Russian at all. Second option: find the desired combination by pressing all the buttons in turn. Now let's move on to the points Android menu System Recovery 3e.

Reboot system now

This menu item does full reboot devices. 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 unusual 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 put this firmware no need. 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 says what to use Wipe Data & Factory Reset It is necessary before each device firmware update.

Wipe Cache Partition

One more 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 paragraph clears internal memory device, then this 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 others are recorded. required parameters. Resetting usage statistics battery, it will be possible to extend her life a little. Yes and 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 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. Once the connection is established, the computer itself will establish necessary drivers for work.

Once the connection is established, you can do whatever you want with the memory card: format, clear, copy 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 such a common error occurs 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 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 broken file firmware, you should download it, connect your smartphone to your 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 Android error System Recovery 3e "No command" is very rare. It only appears when the user tries to install an update via ADB. This method usually doesn't work. As a result, this error appears. So there is no point in using this method. Nothing will work anyway.
