Mobile devices are already quite tightly entered our lives. Now a person cannot imagine existence without a smartphone or tablet. Devices based on the Android operating system are very popular. This OS was developed by Google, and now its market share is incredibly high. Apple's iOS and Windows Phone have a negligible percentage of presence in mobile markets compared to Android. However, like all equipment, devices on this platform have the property of "buggy". Various system crashes are a hallmark of any operating system. No matter how advanced she is. Very often, devices have to be reflashed. But not everyone knows that you can do without such drastic measures. Indeed, in any gadget on Android there is Android System Recovery 3e. How to use it and what is it all about? We’ll talk about this.
What kind of beast is this?
What does Android System Recovery 3e mean? This is a kind of BIOS mobile device. Any operating system has its own BIOS - a basic I / O system that can work even if the main OS is damaged. Sometimes BIOS is unlike the standard one (as, for example, in Android devices). It serves 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 do not even know how to use the recovery properly.
That is why this article is 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 spend money on masters. To do everything yourself is much easier and cheaper. We will analyze each item of the recovery menu and tell everything about it that is possible. So here we go.
How to enter recovery?
It 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 that are not enough. Older models with a mechanical Home button require pressing this button. Some devices require the simultaneous pressing of the power and volume buttons. There are those who must hold 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 a "crooked" translation. Standard methods for entering the recovery in these cases may not work. There are several options here. First: study the documentation of the smartphone (if available) and find the desired key combination. But this option is not suitable for everyone. Most of these devices either do not have any documents at all, or the documents do not have the Russian language at all. The second option: find the desired combination by alternately pressing all the buttons. Now let's move on to the menu items of Android System Recovery 3e.
Reboot system now
This menu item performs a complete reboot of the device. After choosing this option, the smartphone will load the standard Android operating system without any changes. Usually this item is used at the end of all the manipulations in the recovery. Or in the event that they boot into this mode by accident. Although how to do this by accident is unknown. Be that as it may, Android System Recovery 3e, the operation manual of which is simply vital for the user, has such an item. And this has to be reckoned with.
The menu item Reboot system now needs to be used in the last turn. That is, when all operations are completed, all components are updated, factory settings are reset and firmware is installed. This is the essence of the reboot: let the device apply all the changes made. However, after some of them, the smartphone may not boot at all. But this is a completely different story.
Apply Update from External Storage
This menu item allows you to apply the update, which is located on the memory card. By the way, new firmware is also installed through this item if the main OS is not loaded. There are several sub-items in this menu of Android System Recovery 3e. How to flash a new OS? To do this, go to this menu and select Choose ZIP from SD Card, if the firmware is in ZIP format. If it is just an update file, then select Apply Update From SD Card. This is how any device is flashed using recovery. Just copy the firmware file to the root of the memory card, go into the recovery and select the desired item.
There are other subparagraphs in this paragraph that apply in non-standard situations. It is possible to check the MDSUM firmware file. This option checks the file for integrity and if something is wrong, it immediately gives a warning. You can also check the firmware file for compatibility with the device. These are the information options of Android System Recovery 3e. Instructions per se are not required. 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 is able to 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 of which are discussed here, was created just in order to revive the device without serious interference with 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. Otherwise, the new operating system will be unstable. But this is not the worst. If you do not return to the factory settings, then the firmware may not be installed at all, and then the user will receive a completely “dead” smartphone. The instruction in Russian is missing, but the one that is, clearly says that you must use the Wipe Data & Factory Reset item before each firmware of the device.
Wipe Cache Partition
Another useful command in Android System Recovery 3e. The recovery manual says that you need to use this option in tandem with Wipe Data. If the previous item clears the internal memory of the device, this one clears its cache. Namely, the working application files are stored there. Of course, if this is not done before the firmware, then nothing bad will happen. Just in the future, when installing new programs, the device’s cache will grow to incredible sizes. As a result, the smartphone will be very slow. But this is not so scary, since there are many programs for cleaning the cache of the Android OS. And they work great.
It is also recommended that you select this function after a factory reset has been made. This will help the smartphone to become even “cleaner”, which will positively affect the performance of the operating system. The instruction in Russian for Android System Recovery 3e recommends that you perform this procedure precisely after a reset. Before rebooting the device. Then everything will be as it should be.
Wipe Battery Stats
This feature helps to update the device’s battery. After clicking on this item, the battery cache starts to be cleared, in which the current state of the battery, its nominal capacity and other necessary parameters are recorded. Resetting the statistics on the use of the battery, you can slightly extend its life. Yes, and the new firmware will work more adequately with the battery. For some reason, many of the "gurus" of "Android" are dismissive of this option. But actually it is very useful. However, applying it too often is not recommended. 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 the memory card or internal memory, format it or attach it as a drive directly from the recovery. This section can be used if you forgot to drop the firmware file onto the memory card, and there is no desire to restart the smartphone in the operating system. In order to mount the device’s memory card as a drive, select Mount USB Storage. As soon as the connection is established, the computer itself will install the necessary drivers for operation.
After establishing a connection, you can do anything with the memory card: format, clean, copy the necessary files, and so on. In order to unmount a USB flash drive, you should select the Umount USB Storage item on the smartphone screen in recovery. After that, it will be possible to move on to other points of recovery and carry out further resuscitation of the device on its own.
Recovery errors
Sometimes a common error occurs in Android System Recovery 3e, such as canceling the installation of the firmware or package. It can arise for several reasons: the file with the firmware is damaged, incorrect information in the binary file, or the firmware simply does not fit this device. But there is another option: before the firmware, a reset to the factory settings was not made. It is 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 faulty firmware file, you should download it, connect the smartphone to the computer, go to the Mount & Storage menu item and select Mount USB Storage. After that, you can copy the firmware to the root of the memory card again. If you forgot to make a “wipe”, then there is nothing easier than to move a few levels higher and select the appropriate menu item. But the Android System Recovery 3e "No Command" error is very rare. It appears only when the user tries to install the update via ADB. Usually this method does not work. As a result, this error appears. So using this method does not make sense. Nothing will work out anyway.
Conclusion
So to summarize. We tried to describe the features of Android System Recovery 3e. The instruction that came as a result of 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 ultimately will lead to an expansion of horizons and good money savings.
