What to do if the program does not want to function properly? Let's try to figure out why 7 Data Android Recovery does not notice the smartphone, and how we can solve a similar problem.

7 data android recovery identifying the cause of the problem and its solution

The program may not detect certain gadgets for one of several reasons. It all depends on the type of device that is used for connection, as well as the settings directly operating system.

USB debugging disabled

Perhaps the reason presented is the most common. The solution is quite easy - you just need to enable debugging.

1. To do this, you need to go to the settings of your Android smartphone and find a section called “For Developers”.
2. It contains the treasured item - “USB debugging”.

The smartphone is not in standby mode

No matter how strange it may sound, in certain cases the problem with detection can be eliminated by turning on the gadget lock.

The drivers for connecting the gadget have not been updated

Drivers that are out of date or were not installed for identification purposes in Windows may cause the program in question to not function correctly. To correct the situation, you should download drivers latest version from the device manufacturer’s website or update it yourself using the device manager.

Incorrect functioning of the USB driver on the computer

You need to check if everything is system drivers updated to the latest version. It often happens that for the use of certain USB connectors on motherboard, you need to install an additional driver.

Incorrect connection mode

It is worth paying attention that the smartphone should only be connected in storage mode, and not in charging or modem mode. IN similar regimes The program will not be able to detect the SD card.

Lack of root rights on the smartphone

Even if debug mode is activated and mode disk drive enabled, recovery will not be possible without obtaining root rights. More detailed information about obtaining these rights can be found by visiting specialized forums.

USB cable faulty

In some cases, problems may arise in the functioning of the USB cable, which make it impossible to work with the device through programs and file transfers. The phone simply will not be visible to your computer. The only thing that can help here is replacing the cable with a new one or connecting a memory card via a card reader.

To sum it up...

Note that, in the absence of all the problems described above and the program cannot detect the 7 data android recovery device, we can assume that it is simply not supported. IN in this case, you can try using one of previous versions program or any of its analogues.

Hope our program can help you

Problems with smartphones are quite common. They are caused by many reasons that do not always depend on the user. There are also software errors. Why doesn't 7-Data Android Recovery see my phone? What kind of program is this anyway? How to work with it correctly? The answers to these questions are presented in the article.

Program

So, 7-Data Android Recovery is a program that was Russified not so long ago. It is needed to recover data from a smartphone running the Android operating system. If, through your fault or due to software failures, personal data was lost, in order to restore it, you need just such an application. The interface is intuitive, so no problems should arise when returning your photos.

Getting started

Before we understand why 7-Data Android Recovery does not see the phone, what to do in this case and what are the causes of this problem, let’s look at how exactly the program works. You can download and install the application from the official website. Here you will also find a version for PC. If any data has been lost from your computer, 7- Data Recovery Suite will help you restore them.

It is in this application that there is a special section for Android devices. The operation of both utilities is almost identical, at least regarding the mechanism.

Preparing your phone

To try to recover lost photos, you need to connect your smartphone via USB to your computer. As practice shows, it is advisable to immediately disable USB debugging on the device. Sometimes users forget about this operation, then a problem may arise that 7-Data Android Recovery does not see the phone.

Let's go to settings. Here you need to find the line “For developers”. It also has a USB debugging function. You may not find such a section; to do this, you will need to configure it.

Connection

So, you have connected your smartphone via cable. You need to open the program. A simple menu will appear in front of you, in which everything is clearly indicated and described. There are recommendations here that need to be followed. This refers to USB storage and connection via a device cable. Then you need to click “Next” to continue the setup.

You will see a list of storage devices that are on your smartphone. There may be a section of internal memory and external storage. If you don’t have a memory card, then there will be only one section. You need to select it and click “Next”. Choosing the right partition depends on where your files disappeared from.

Next, the program begins scanning the device. Upon completion of this process, the utility indicates lost, deleted, damaged files. The list may be empty if the device has irretrievably destroyed the documents. There may be a huge number of folders among which you need to look for what you need.

If you find a file or folder, click on it and click “Save”. If several files have been lost, you can check the box next to each one and save it again. Afterwards you will have to specify the folder where you want to restore the found data. It is recommended to send them to a PC rather than a smartphone.

Error

But the instructions described above are suitable for those who were able to connect the device. What if 7-Data Android Recovery does not see the phone? This can be caused by many errors. But most often this is due to the fact that the computer itself does not want to detect the smartphone.

The problem is common. There are many possible solutions, as well as reasons. Maybe the wire is simply damaged, or maybe there is an error in the PC system itself.

Debugging

This is one of the common options that occurs when 7-Data Android Recovery does not see Lenovo phone. What some users miss is that they need to enable USB flashing. This process makes it possible to indicate to our computer that we want to turn on the device in a special mode.

Depending on the OS revision, you need to approach configuring this mode differently. If you have Android 2.3, then in the settings you need to go to the “Applications” section and find the “Development” line there. In later versions, the “Developer Options” option appeared directly in the settings.

Starting over new version OS, you need to go to the “About phone” line in the settings. Here we look for “Build number”. This line is not active, but we can click on it. You need to do this several times, as practice shows, about seven clicks. Information will appear at the bottom indicating that you have become a developer. Now the “Developer Options” line will appear in the settings.

In new operating systems, this menu may also be located in “ Accessibility" Here you will have to look in the settings in different tabs.

Modes

7-Data Android Recovery does not see your LG phone because you have set the wrong connection mode. Some users connect their smartphone and see that it just starts charging. Of course, sometimes this is due to problems with the device itself, but most often the wrong connection is selected.

You need to go to settings and find the menu for connecting a device via USB. Depending on the phone model, you will also have to look for this item. For example, Meizu hid this item in “About phone” - “Memory”. Quite illogical, especially for those who have previously used other models.

There are four modes in this menu. You need to use “Connect as media device (MTP)”.

USB

The 7-Data Android Recovery utility does not see samsung phone in case there are any connection problems. This is the first thing to check. Maybe the cable is simply damaged, or maybe the problem is in the connector.

To do this, you need to try changing the wire and connecting through other ports. If the program sees the smartphone, then the problem is clear. If not, move on.

Drivers

The computer, and therefore the 7-Data Android Recovery utility, does not see Sony phone, because the drivers for USB controllers, or more precisely, for the smartphone, are outdated. To check all this, you need to go to “Device Manager”. All connected devices to our PC will appear in the window in front of us. We are looking for controllers, and in them is our connected device.

You need to click on it and select “Properties”. We look for the “Driver” tab at the top, go to it and click “Update”. If there are drivers on the PC itself, you can manually specify the path to them. If they are not there, then run an automatic search.

Additional options

There are even fewer probable reasons similar mistake, but still they should also be excluded. As practice shows, it is possible that the memory is full. You can try cleaning and removing unnecessary files. Perhaps the system is busy with third-party processes and simply does not allow you to connect to your PC.

If 7-Data Android Recovery does not see your phone, there is a possibility that the utility does not support your device model. Unfortunately, this sometimes happens, especially with outdated models. If this is the case, you can find other analogues of the application on the Internet. For example, not bad Android option Data Recovery. The utility is practically a copy of 7-Data Android Recovery.

It recovers data, finds lost files, and returns incorrectly deleted ones. The program works with the operating system Android system. Due to the fact that the interface of this utility is just as simple and clear, working with it will not cause difficulties.

But remember that you should also not forget about the “USB Storage” mode. Despite the fact that many people neglect these instructions, without them errors and failures will occur. So first set up this mode. Then connect your smartphone to your PC.

After launching the program, it will immediately be clear whether it sees your phone or not. There is another option - connect the device via wireless interface via Wi-Fi.

Conclusions

If you have lost any data, you can still recover it using similar programs. The question is: what to do if they don’t see the phone. Then you have to sit for an hour or two to figure out the problem and find out whether the wire is simply damaged, or the smartphone is not working correctly, or whether you are doing something wrong.

Due to various failures of equipment running on the Android operating system, or erroneous user actions, sometimes important data is lost from the device. This can be video and audio content, photographs, contact information. Therefore they are popular various applications to recover deleted files. One such program is 7 Data Android Recovery, which has good functionality and a user-friendly interface.

Any software designed for data recovery uses various algorithms. Loss of information and files can occur due to the following actions: accidental deletion, malfunction of the gadget’s flash memory, errors during the operation of the operating system. The operation of file recovery means finding data remains, extracting them and correcting them.

Android does not use an encrypted file system, so deleting data does not actually mean destroying or changing it. In fact, the file is simply marked by the system as deleted. That is, the data does not disappear, but the place where it is located may be overwritten. Since overwriting does not occur immediately when a file is deleted, successful recovery is possible in almost 99 percent of cases. Moreover, the more intensively the OS is used after deletion, the less likely it is to recover information.

It is more difficult to remove it if damaged file system or full formatting. In this case, applications use a search algorithm based on signatures - unique identifiers. For example, 7 Date Android Recovery sequentially scans all memory according to the principle of antivirus software, identifying files using the necessary signatures. If the file is also fragmented (broken into blocks of different lengths located in random places on the disk), then the application has to supplement the signature search with information from the file system.

This operation takes for a long time. Due to the difficulties in supporting various signatures, there is a certain limitation on supported formats. In order for the OS to navigate the information located on memory cards, it creates a file that indicates which sectors are occupied by the data being sought.

Android Data Recovery begins its search from the location of the beginning and end of the file. The size of the data is determined by analyzing the title or reading the sectors following the title. But in any case, the result of recovery largely depends on overwriting the file system and fragmentation of partitions.

Features and Disadvantages

Like any program, 7 Data Recovery has both advantages and disadvantages compared to its analogues. But it owes its popularity precisely to the predominance of positive opportunities. It occupies a leading position in the ratings of various publications and user reviews.

The advantages of the application include:

• recovery of files after exposure virus attack, deletion or formatting;
• finding and returning the partition structure;
• ability to work with both external and internal memory of the Android system;
• search system with filtering according to various criteria;
• sketch preview of graphics before restoration.

The advantages of the program also include an intuitive interface and good Russian-language localization. In addition, they note the presence of a convenient recovery wizard, a separate function for finding media files, fast work when decoding data encrypted by viruses. Users note a fairly high degree of recovery of lost information.

The disadvantages include the rather high activation cost full functionality. This is due to the fact that the utility is distributed as shareware. That is, it can be downloaded and installed for free, but it will be impossible to return data exceeding the total size of one gigabyte without purchasing a license.

Installing and using the application

Android memory data recovery is done using personal computer. The installation files are downloaded to a PC, to which a smartphone, tablet or other Android device is connected via a USB connection.

The easiest way to get the application is to download it from the official website. Once on home page, you can choose Russian as the main language, but only title page.

It is important that the utility can work not only with Android, but also with Windows and Mac. After installation is complete, you are offered to immediately launch the program, but before you use 7 Data Android Recovery to recover data, you will also need to connect the smartphone or tablet with the missing information to the PC.

Menu and appearance

When you launch the application it will load immediately simple type an interface made in the form of buttons similar in style to the Windows 8 buttons. Each is nothing more than a submenu leading directly to launching the recovery tool.

When you select the "Advanced Recovery" button, a new window will appear in which you will need to select the media type, and then click the "Next" button to begin scanning. The same actions are performed when selecting “Recover deleted files”. In this case, the search process will be faster, but not as thorough.

Clicking on “Recover disk partitions” will bring up a menu with a choice of the search location previously existing sections. The “Recover Media Files” button will display a tree view of the internal and external media, in which it will be possible to specify the search location. When you click on “Android recovery” you will be asked to enable USB debugging on your gadget and then connect it to your PC. After which the scanning will begin and it will be possible to recover files.

Required files are checked, and after right-clicking and specifying the save location, they are restored.

Connection errors

It happens that 7 Data Android Recovery does not see the phone or other gadget connected to the PC. Most often, this situation occurs due to the fact that the “USB Debugging” option is not enabled on the device. To enable it, you will need to go to the device settings and select “For Developers”. By default this item is hidden - for it to appear, you need to do the following:

1. In the gadget settings, find the “About phone” item and select it.
2. In the list that appears, click on the “Build number” line seven times in a row.
3. After the notification “Congratulations, you are now a developer” appears, go back a step.
4. Find the “Developer Mode” item and enable debugging there.

If debugging is enabled, but the device is still not detected by the program, then possible reason There may be outdated or missing drivers for the gadget. It is recommended to go to the smartphone or tablet manufacturer's website and download and then install the latest driver package. But there is also a possibility malfunction Windows OS, namely software implementation support for USB hubs. Therefore, it is worth updating or reinstalling the drivers on the motherboard.

Except software problems, there may also be hardware ones. These include: damage to the USB cable, non-working ports on the computer motherboard or the device itself, failure of the internal memory in the Android device. When using cords poor quality The PC does not detect the device due to weak signal, so you should only connect to the rear ports of the motherboard.
