• What to do when the PC does not see the smartphone. Error: USB MTP device. Failure: recommendations for troubleshooting the problem

    IN lately synchronization of mobile gadgets based on Android OS with standard ones computer systems has undergone quite significant changes. The basis new technology it was supposed to use the so-called MTP Device driver when directly connecting the device to a computer or laptop via universal port USB.

    What is MTP Device?

    In general, the technology first saw the light back in 2008 on mobile gadgets with Honeycomb in the Android OS Ice Cream Sandwich. At that time she was considered integral part Windows package Media, but was then standardized as one of the main types of USB devices.

    That is why now stationary operating systems when connecting mobile gadget and define it as MTP Device. In fact, the development itself was not something new, since it very much resembles the PTP (Picture Transfer Protocol) protocols, or rather, it is one of its varieties in the form of additional extensions.

    MTP Device Driver as an alternative to USB Mass Storage

    As for the functioning of such a system, it is probably clear that without installing a driver it is in principle impossible. However, compared to conventional data exchange via USB MTP Device driver works a little differently.

    The most important difference, also known as the advantage of the new technology, is the following. The point is that when using standard connection with the help USB Mass Storage two sections are created (for media files and for applications separately), and one of them always depends on the other. A situation arises when a smartphone or tablet does not have access to one of the sections, but the computer perceives both. This is why a situation arises when applications installed on an SD card not only do not work, but do not even start.

    There are no such restrictions when using MTP Device. In addition, there is no need to even use a file FAT systems. And if earlier redistribution free space occurred due to the influence of one section on another, in in this case there is nothing like it. Simply put, it used to be a hobby free space one partition led to a decrease in the size of another. Now both sections remain unchanged.

    Standard driver installation on Windows

    Now let's see how it is produced standard installation drivers when synchronizing the device with Windows. Let's say we have a Samsung smartphone or tablet.

    As a rule, usually when you first connect a device to a computer terminal, the system displays a message in the system tray that a new device has been found (in our case, MTP Device Samsung). The system itself installs the driver necessary for synchronization without any problems, after which data transfer can be carried out in the same way as using a regular USB connection, when it is determined and internal storage, And external SD card. Of course, errors may appear (like “ Samsung Mobile MTP Device driver is not installed"), but we will dwell on them a little later.

    General recommendations for installing drivers for most Android devices

    In principle, it almost always works automatic installation necessary drivers the Windows operating system itself. However, you can also use alternative methods related to the installation of related utilities for a smartphone or tablet.

    For example, the same Samsung MTP Device driver is installed automatically if you have the latest version of the Kies application. Please note, for each specific model mobile gadget corporation Samsung drivers doesn't release them, so look for them, say, for S6 or for Galaxy Note 2 makes absolutely no sense.

    For HTC smartphones you need to use specialized software called HTC Sync Manager(sometimes you may need to install the firmware via FastBoot mode). For LG, you can find a driver on the manufacturer’s official website specifically for a specific model. For Nexus, you need to use the ADB RUN utility and install the driver from the standard Device Manager. When using Sony gadgets, there are two options: installing Sony PC Suite or using FlashTool drivers. In principle, there is no difference, but you need to remember that these are two mutually exclusive programs - when installing one, you must first remove the other.

    Use on Mac OS

    The use of devices classified as MTP Device when synchronizing with desktop Macs or Apple laptops is not much different from its counterpart in Windows.

    Unless, to be completely sure, you can additionally install Android app File Transfer, that's all. Otherwise there shouldn't be any problems.

    Installation on Linux (Ubuntu)

    IN Linux systems due to their specificity, installing MTP Device drivers looks somewhat more complicated. As an example, consider this process when installing a driver for Nexus.

    So, we use the command window, in which we first write sudo nano -w /etc/udev/rules.d/51-android.rules (installing UDEV rules). Then enter the command SUBSYSTEM=="usb", ATTR(idVendor)=="04e8", ATTR(idProduct)=="6860", MODE="0600", OWNER="<Имя пользователя>", after which we sequentially execute the lines sudo apt-get install mtpfs, sudo mkdir/media/GNexus and sudo chmod 775/media/GNexus.

    Next, connect the gadget to the computer and enter sudo mtpfs -o allow_other /media/GNexus. That's it, now, using Nutilus, you can start moving any files and folders. Yes, the most important thing. When all operations are completed, remember to use the final command sudo umount mtpfs.

    Possible errors and methods for eliminating them

    Unfortunately, errors cannot be ruled out either. In most cases, this applies only to operating rooms Windows systems. Let's try to look at the most common failures and the simplest methods for eliminating them.

    First of all, it is worth checking whether the accompanying utilities are up to date with the latest versions. When using them, it is advisable to download the latest distribution from the manufacturer’s website.

    If the driver for MTP Device still does not work, you can try to reinstall it manually. To do this you need to go to “Device Manager”. In theory, if the driver is not installed or the device itself is not working correctly, it will be marked yellow icon. Everything is simple here. You need to find the driver update button in the properties, and then select from the list only compatible devices. If this does not help, you will have to remove it and then install it again in automatic mode. If this does not work, you will have to tell the system the location where it is stored. installation distribution containing the necessary information.

    Sometimes, however, this does not help. There can be any number of reasons. In some cases, installing the latest software on the system may help. Windows versions Media Player. You'll probably just have to check the system hard section disk for errors, but you never know what could happen. It also happens that this type errors or failures may be caused by the “native” media player itself (this option, unfortunately, cannot be ruled out). In this situation, if you are using versions of Windows 7 and higher, you can simply try to disable multimedia components in the programs section of the Control Panel.

    As is already clear, the reasons for such failures are simply innumerable. Therefore, we will have to move from the simplest methods of solving the problem to more complex or even radical ones, taking into account the specifics of the cause in each specific case and for each specific device.

    However, as practice shows, one of universal solutions may be used system registry. Here you need to find the UpperFilters key in the main section HKEY_LOCAL_MACHINE by sequentially moving through the tree (System\CurrentControlSet\Control\Class) and delete it. This will not affect the performance of the operating system, but the connection will work as expected. Let us immediately note that in most cases this method can be used for gadgets from Samsung.

    Conclusion

    That’s basically all that concerns the main issues related to using a connection using MTP technology. As you can see, you don’t have to work hard to install the driver, except on Linux. Basic errors can be resolved quite easily, but in each case it is advisable to find out the root cause before taking any drastic actions like deleting registry keys. But in most cases there should be no failures, especially if you install the most latest versions additional software for your gadget.

    In any case, you can simply turn to the official Internet resources of mobile equipment manufacturers. Surely there is a help section with a description of problems of this type. Perhaps the problem is not even in Windows, but, for example, in the device’s firmware or disabled functions and settings.

    Android from A to Z: What lies behind abbreviation MTP, and how to properly manage it

    MTP (Media Transfer Protocol) first appeared on devices with Honeycomb. The protocol is slightly different from the usual USB Mass Storage (UMS), in which you turn on the USB mod and start moving files. And since MTP became part of it, it would be nice to find out all the nuances. In this post we will try to understand as much as possible what exactly this protocol is, what is the need for it, and how to configure it to simplify file transfer.

    What is MTP?

    MTP is a set of custom extensions for PTP (Picture Transfer Protocol), which is aimed at transferring files and associated metadata across USB. Still here? Then let's continue.

    Originally part of the structure Windows Media, but in 2008 MTP was standardized as a type USB devices, thereby becoming an established standard. If you have owned an iriver or Creative MP3 player, you have probably encountered MTP. If you use digital camera, which is automatically recognized as a device when connected to a PC, then the RTR, which is essentially the same as MTP. The thing is quite old, but not for Android.

    Why use MTP instead of USB Mass Storage?

    The essence of use MTP is that now manufacturers mobile devices no need to create two separate sections, one for applications, the second for media files. Previously, a sin was noticed behind them, which consisted in expanding the second partition at the expense of the first, and this very often led to a lack of space for new applications. WITH MTP Both types of files can be stored together.

    U USB Mass Storage There is one big drawback - when you create memory partitions, one of them is completely at the mercy of the other device. This means that your tablet or smartphone will not have access to this section, but the computer to which the device is connected can manage it in every possible way. For this reason, some applications and, especially, widgets placed on the SD card do not work.

    Another advantage MTP is no need to use file system FAT for storage. This ultimately leads to more fast work device

    Installation of MTP

    Since the time Windows XPMTPdevices work without problems. Connect yourGalaxyNexus, choose MTPas a connection type, the computer operating system itself finds necessary drivers, you will only need to wait a little. Moving files between your smartphone and PC without any problems is ensured. But what should those users who preferredLinux And Mac?

    Mac OS


    Install UDEV rule opening rules file via terminal

    sudo nano -w /etc/udev/rules.d/51-android.rules

    Then enter the following line at the bottom of the file (remember to include your username):

    SUBSYSTEM=="usb", ATTR(idVendor)=="04e8", ATTR(idProduct)=="6860", MODE="0600", OWNER=" "

    After which it will be the turn for:

    • sudo apt-get install mtpfs
    • sudo mkdir /media/GNexus
    • sudo chmod 775 /media/GNexus

    Then you should connect Galaxy Nexus to the PC and in the same window as before enter:

    sudo mtpfs -o allow_other /media/GNexus

    This will all allow you to drag and drop files using Nautilus, and don't forget to enter the following command when finished:

    sudo umount mtpfs

    Alternative


    Alternatively you can use the combination Wifi File Explorer And QuickSSHd And send files over a wireless connection.

    Standard driver installation on Windows

    Now let's see how a standard driver installation is performed when synchronizing a device with Windows. Let's say we have a Samsung smartphone or tablet.


    As a rule, usually when you first connect a device to a computer terminal, the system displays a message in the system tray that a new device has been found (in our case, MTP Device Samsung).

Of course, errors may appear (such as “Samsung Mobile MTP Device driver is not installed”), but we will dwell on them a little later.

    General recommendations for installing drivers for most Android devices

    In principle, the automatic installation of the necessary drivers by the Windows operating system itself almost always works. However, you can also use alternative methods related to the installation of related utilities for a smartphone or tablet.


    For example, the same Samsung MTP Device driver is installed automatically if you have the latest version of the Kies application.

    If you are reading this article, then it is obvious that you are having trouble transferring files via USB on your Android device. Don't worry, you are not the first person to contact us with such a question.

    Fortunately, we know several ways to solve this problem. So, without further ado, here's what you need to do to get USB file transfer working again.

    Cause of USB file transfer error

    There are several reasons why you may not be able to transfer files via USB:

    • USB cable does not support file transfer
    • The device is not configured to accept files via USB
    • You have installed Samsung app Kies
    • The Micro-USB port on your Android device is broken (unfortunately I can't help you with that)

    Step 1 – Enable File Transfer on your Android Device

    This is the first thing you should do to be able to transfer files via USB to your Android device.

    To enable USB file transfer, go to Settings > Storage > Click on the three vertical dots on the right top corner screen> USB connections to your computer > Check the box next to "Media device (MTP)"

    If you think the problem with USB file transfer is software related, try connecting the device to a computer with via USB, select “Camera (PTP)” and remove it again. This helps some users.

    Step 1.1 - addition for the “clean” version of Android 6.0 Marshmallow

    If you don't see the above option under Memory, make sure you enable USB debugging. After that, do a little trick:

    1. Disconnect the USB cable from the device.
    2. Enable developer mode. To do this, go to Settings > About phone > tap on the build number several times until a pop-up message appears that you have become a developer.
    3. Go to Settings > Developer Options.
    4. Enable USB debugging.
    5. Lock your device (lock button on the side or top).
    6. Connect your smartphone to your computer using a USB cable.
    7. Unlock your Android device.
    8. Swipe down to open the notification panel and tap on USB Charging.
    9. Select "File Transfer" from the pop-up window.
    10. Lock your device and unlock again.

    Using this method, you will be able to transfer files via USB. For some reason this option is not available without Developer Mode enabled.

    Step 2 – Uninstall Samsung Kies program

    Skip this step if you don't have the software installed Samsung Kies.

    Samsung's official file transfer program often causes interference when transferring files via USB. To remove Samsung Kies, you need to first download the program and then select “Uninstall”.

    Step 3 – Check USB Cable

    Not all USB cables are created equal: some are capable of transferring files, some are not. Recommended to use USB cable, which comes with your Android device. Typically, they have a USB file transfer feature.

    If none of the methods helped solve the problem, then try installing AirDroid. Given software allows you to transfer files to Android devices without USB cable.

    In this article we will figure out how to connect Android to a computer/laptop via USB as a flash drive and be able to transfer information without using a classic flash drive.

    This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

    Before Android 4.4 KitKat, it was possible to connect via USB as a flash drive. The PC saw the device as removable disk and provided the same rights: the user could also perform other actions.

    Then in new versions of Android USB mode was replaced by MTP, in which only the data transfer function remained, and the same formatting did not work.

    Setting up a USB connection

    To manage the connection to a computer via USB, you need. To do this, add to the settings Android section“For developers” (if it doesn’t exist):

    1. Open settings.
    2. Go to the "About phone" or "About device" section.
    3. "Build number" or "MIUI version".
    4. Press (click) on this item until you see a message that you have become a developer (usually 7-10 clicks are enough).
    Increase

    After the developer section appears in the settings, you can enable USB debugging. The item is called that way, so you just need to move the slider to the “On” position and confirm the resolution.


     Increase

    Now you can connect the device to your computer via USB and select the operating mode. IN latest versions Android most used are:

    • MTP - transfer any files from computer to phone and vice versa.
    • PTP - transfer of photos, as well as transfer of files not supported in MTP mode.
    • Charging only.

    Connecting in USB storage mode

    If you can't get used to using the media player, go back to using USB storage mode. For this you will need:

    This method may cause damage system files. In this case, you will have to reflash Android.

    To connect Android to your computer as a drive:

    1. Launch USB MASS STORAGE Enabler.
    2. Grant superuser rights and agree to change how Selinux works.
    3. If the device is supported, the main application menu will open.
    4. Click "Enable USB MASS STORAGE".

     Increase

    Now, when connected to a PC, the phone or tablet will appear as a drive. To connect in MTP or PTP mode, just restart the device. Once you're done with mass storage mode, go back into the app and disable USB MASS STORAGE.
