The phone does not connect to the laptop via USB. Connection in USB storage mode. When the problem is a broken physical interface
The computer and phone are connected to each other to transfer data. The phone can also be used as a modem, flash drive, or webcam. The connection is made without the help of the Internet, and the data transfer speed is very high. They can be transferred in any direction, to the phone from the computer and vice versa. The connection can be either cable or wireless. Cable is usually more convenient and provides excellent speed. Here we will look in detail at all the ways to connect your phone to a computer.
Most often, you need to transfer multimedia files from your phone to your computer for further processing. Modern phones can connect to a computer in several ways.
Existing connection options
Connection methods are determined by the network card interfaces and connectors installed on both the phone and the computer. With good equipment, there are three ways:- via USB cable connection;
- via Wi-Fi;
- via Bluetooth.
The advantages of wireless connections are speed when everything is already configured and addresses are registered. The second advantage is the absence of mechanical impact on the connector. With frequent use, for example, when daily downloading fresh photos from your phone to your computer, the micro-USB connector will very quickly become loose and fail. This definitely won't happen with wireless connections.
Using Wi-Fi
A Wi-Fi adapter must be installed on the computer. Laptops, netbooks and tablets almost always have it built-in. On desktop computers, a small Wi-Fi card with an antenna is installed on the rear panel of the system unit. Sometimes you come across built-in Wi-Fi modules in motherboards. To connect a phone, the module form factor is not important.If you just turn on Wi-Fi on your phone, your computer won’t see it. The point here is that it does not broadcast packets with the network name, so it is recognized as a client, and not as a point. The developers specifically made Wi-Fi clients “invisible” to others. Therefore, before you connect your phone to your computer via Wi-Fi, you need to reprogram it from a client to an access point. This can be done using a mobile application.
In any official application store you need to say a free FTP server program. The procedure for downloading and installing this mobile application is standard and no different from others. An FTP server is often implemented in hardware. Technically, it's a hard drive connected to a modem. It can work autonomously, without a computer. At the same time, you can record files on it and download them. Exactly the same functions will appear on your phone after installing and configuring the corresponding mobile application.
After installing the application, you must type your phone's address (which is now recognized as an FTP server) into your computer. Type it in the address bar manually and save. Once the application is downloaded and configured, and the address is saved, connecting via Wi-Fi will become very simple and convenient. It is well suited for frequently connecting a smartphone. In this case, the resource of the USB connector will be saved.
USB connection
This is the easiest and most common connection method. You don’t need to download any applications or understand their English-language interface. You just need to connect your phone and computer with the cable that comes with the package. The advantages of the method are speed and simplicity. It is also important that the phone is automatically recharged while connected. The computer is a powerful power source. Many note that charging is even faster than from a mains charger.When connected via USB, you can configure access to folders in the phone’s memory and on the SD card installed in it. USB cables are universal. There is no need to use only the standard cable included in the kit. The weak point of the cable connection is the micro-USB connector. In repair shops it is often replaced, since it is quite loose on the phone.
Bluetooth connection
The Bluetooth module on the computer is designed to connect wireless headsets. The phone is connected by simultaneously activating the search mode on both devices. Then, on your computer you must select it in the list and connect. Compared to Wi-Fi, Bluetooth has less power and is therefore safer in terms of harmful electromagnetic radiation. The connection speed is approximately the same. Technically, it is lower, but data is rarely transferred at full speed.
Possible problems
If the phone is connected for the first time, the system begins to automatically install drivers. Here you just need to wait for them to install. Also, at this moment, a good Internet connection must be provided so that the necessary drivers are downloaded automatically. Automatic downloaders do not always work. Many antiviruses disable them. In this case, you need to install the drivers yourself. The installation procedure varies significantly depending on the version of the computer's OS and the settings of the smartphone. There is only one universal piece of advice that can be given here - follow the instructions on the screen and do not use pirated drivers. Original drivers are almost always free. Download them.
Technical compatibility between phones and computers is not fully ensured. So computers running Windows XP cannot be connected to all smartphones running Windows Mobile. iOS also has similar limitations. You can take this opportunity to update the operating system on your computer. Another option is to switch to a Wi-Fi connection. It works through any more or less modern browser.
A fairly common problem lies purely in the hardware. The micro-USB connector is simply loose. It uses two contacts for charging and they can work, while the rest of the data contacts no longer function. This problem is very easy to notice if, during the connection, you begin to inspect the wire and change its position in space.
What to do if the connection fails?
You need to find another way to transfer data or change your computer, try to use an intermediate device, such as a tablet or laptop. Data can be transferred by physically removing the SD card from the phone and inserting it into the card reader on the computer.Possible reasons include incorrect connection actions, outdated or incorrectly configured software, malfunctions of USB cables, ports, or the devices themselves.
Follow the tips listed below, they can save you from many connection problems.
How to properly connect Android devices to your computer via USB
If you have Windows, ignore this paragraph. If you're using macOS, install Android File Transfer.
Make sure your mobile device is turned on and connect it to your computer. Then lower the notification panel on the gadget - you will see a special switch. Click on it and select the “File Transfer” mode in the menu that appears. The names of the modes may differ depending on the Android version and device model.
After these steps, the computer should see the mobile device. On Windows it will appear in Explorer, on macOS it will appear in the Android File Transfer window. But in the case of a Mac, you will need OS X 10.5 and Android 3.0 or later versions of these OSes, otherwise it will not work.
How to properly connect iOS devices to your computer via USB
Make sure your mobile device is turned on and unlocked, then connect it to your computer. The first time, iOS will ask for permission to access media files and you will need to give it.
In the case of a Windows PC, the connected iPhone or iPad will appear in Explorer in the media devices section. They will appear like regular digital cameras - you can view and copy photos and videos. To access other data, you will have to use iTunes, which can be downloaded from the Apple website. The registration procedure will not cause any difficulties, you just need to follow the prompts of the setup wizard.
On Mac everything is a little simpler. iTunes is already included with macOS, so it will launch automatically when you connect your iPhone or iPad. Interaction with content is carried out through a media harvester, but iTunes is not needed to access media files. The standard Photos application will help you view and import them, which also launches automatically when iOS devices are connected.
What to do if the computer does not see the USB device
1. Disconnect unnecessary USB devices from your computer.
2. Try connecting through a different cable or port.
3. Restart your computer and mobile device.
4. If you have Windows, update the driver required to recognize the USB device.
Launch the command line (Windows keys + R), paste into it devmgmt.msc and press Enter. When Device Manager opens, find the connected gadget in the list of equipment.
Right-click on the device and select “Update driver” → “Search for drivers on this computer” → “Select a driver from the list of available drivers on your computer.”
In the list of drivers, check "USB MTP device" and click next to reinstall.
5. If your device doesn't show up in iTunes, please use Apple's guide to resolve the issue.
6. Update the operating systems on your computer and mobile device to the latest versions. If you are using Windows Vista or XP, first try installing the MTP protocol by downloading it from the Microsoft website.
7. Check the functionality of the port in the gadget by connecting it to another computer. If the problem persists, contact the manufacturer's support team.
What to do if the computer does not see the device connected via Bluetooth
If you encounter visibility problems when connecting via Bluetooth, try the following measures. Do these steps one at a time and maybe one of them will help you.
1. Make sure that Bluetooth is turned on on both devices, and that visibility mode for all other devices is activated in the settings on each of them. On iOS, these settings are included in the AirDrop service, available in Control Center.
2. Place your tablet or smartphone closer to your computer.
3. Restart your computer and mobile device.
4. If the devices successfully connected to each other before, delete the saved pair in the Bluetooth settings and try to reconnect.
5. Update Bluetooth drivers on your computer.
6. Update your device operating systems to the latest versions.
Alternative connection methods
You always have a backup option - services with which you can transfer files between a computer and a mobile device via the Internet. These are AirDroid, Pushbullet, as well as cloud storage services like Google Drive, OneDrive and Dropbox. They will allow you to do without Bluetooth and USB if these options do not work or are not suitable.
The simplest solution to connect an Android phone to a computer via WiFi is ES Explorer. The application is free and has a clear interface, but most Android phone owners limit themselves to using it only as a file manager. To open the network capabilities of the program you must:
If the connection is successful, all directories on the computer available for public use will be displayed.
To open files from your phone to your computer via WiFi, it is recommended to use another menu item: “Network -> FTP”. No authentication or selection of additional settings is required. The application will independently create an FTP server on your smartphone, open the required port and provide a ready-made link for connection.
You can view or download files from your phone via WiFi in any browser. It is enough to enter the specified data in its address bar.
If, in addition to viewing files, you need to download from an Android device or upload folders to it, this can be done through standard operating system applications. To do this, just enter the server address that was provided by the program directly into the “Explorer” line. Directories located in the smartphone’s memory will open in the same form as files and folders on the computer itself.
Important! The most complete use of the smartphone's file system when connecting in this way can be achieved using specialized FTP clients, such as FileZilla or SmartFTP. But even when working through the standard File Explorer file manager in Windows, you can copy files from and to your phone.
Using the AirDroid app
In addition to viewing files on your smartphone, this application ensures full synchronization of your phone with your computer. Connecting to a computer via WiFi is carried out in several stages.
It is important to remember that the Android device and the computer must be connected to the same network. Moreover, if a router is used, a wired connection can be used for the computer, and the smartphone will connect via WiFi. If difficulties arise at the synchronization stage, the smartphone may be connected via mobile Internet.
After synchronization is confirmed, the connection to the phone is completed. Almost any action that can be performed can be done remotely, via a computer and a WiFi connection. The interface is designed as a separate desktop. In the upper right corner, information about the device and the amount of free memory are displayed. Just below is the control panel, with which you can send files and folders from your computer to the device.
The icons on this desktop work like menu options on the phone itself. For example, the call log displays full call details. Synchronization is performed in both directions - with the ability not only to view records, but also to delete them. The changes will be applied on the phone.
When you open contacts, all numbers in the smartphone's memory are displayed. People from the address book can be sent SMS or called using a computer.
One of the interesting features of the application is the use of the Android device’s camera. There are not many practical applications of this feature, since the phone is already within the range of the WiFi signal.
Connecting to the device screen via WiFi works in the same video streaming mode. There may be a delay when updating information, but it is not so large that it interferes with your experience.
AirDroid also allows full access to the smartphone's file system, just like ES Explorer. Data on the phone is transferred via WiFi in both read and write mode.
If the computer does not see Android via USB, then you will not be able to download photos, videos or music, install applications not from the Play Market, or flash the device. And this is very bad, because the functionality of the phone is not fully revealed due to some stupid error.
Someone might argue that you can flash a phone without a USB connection, but for transferring files there is Wi-Fi, instant messengers, cloud storage, and finally email. But I just can’t refuse a USB connection; I constantly carry a cable with me and consider it one of the most convenient ways to transfer data.
Checking the cable and port
Before you go into your phone settings, install drivers and curse the day you bought this Android, check the cable and USB port. I was once very surprised that the computer stopped identifying the smartphone, which it had previously seen perfectly well. It turned out that the cat liked the cable and chewed it through. From this situation I drew two conclusions: the wires must be put away in a box and inspected before connecting. The cat did not draw any conclusions. If no kinks, bites, breaks or other mechanical damage are found on the wire, check the USB port. Try connecting to a different connector or inserting another device into the same port - for example, a mouse.If Windows XP is installed on your computer, then urgently look for an opportunity to upgrade to at least “seven”. But first you can just install MTP protocol so that XP learns to work with Android. The trick is that when the first version of Android appeared, Microsoft had already released Windows 7. Therefore, there is no MTP protocol in XP, and you have to install it separately. You can download MTP
If the computer detects any other device, but the phone categorically does not want to see it, then it’s time to shift the focus to Android settings and connection features. Yes, there is a possibility of mechanical damage to the microUSB connector on the phone, but I have not encountered this yet. If you have something broken, you will most likely notice it.
Most often, the inability to establish a connection between a computer and a phone is due to software errors. If none of the methods listed below help solve the problem, contact a service center - it seems that the smartphone really needs repair.
Android setup
I came across two situations. The first phone required not only obtaining developer rights and enabling USB debugging, but also installing phone drivers on the computer. In the settings of the second smartphone, I did not find any parameters responsible for connecting via USB. They are not needed: the phone is perfectly detected by the computer, after which it offers to select a connection mode.So, if you connected your smartphone, but nothing happened:
- Open Android Settings.
- Go to the section "About the phone"(may be called “About device”).
- Find build number(models) and click on this item until a notification appears that you will soon become a developer. Usually n press 7-10 times.
After you become a developer, a new section will appear in the Android settings - "Developer Options". Inside it you will find a switch "USB Debugging", which needs to be moved to position "On".
Now try connecting your phone to your computer again. When connecting, a mode selection window should appear on the smartphone screen. The default setting on older versions of Android is “Charge Only”. If the window does not appear, slide it out of the notification shade.
To transfer files, you need to select media device (MTP) or storage mode. Among the options there will also be a PTP mode, but it is only suitable for photos that can just as easily be moved to MTP.
After selecting the appropriate mode in “Computer” on Windows, a media device will appear, the contents of which you can work with. Depending on your phone model and Android version, the internal memory and SD card may appear together or as separate drives. But this does not matter, the main thing is that they are displayed at all.
There are no other options in the Android settings that are responsible for connecting via USB, except for debugging. However, there are some peculiarities. For example, on Nexus smartphones, you need to unlock the screen, which is protected by a password or pattern, in order for the computer to access the contents of the memory.
Also, USB connection cannot be established if tethering mode is enabled on Android. To check its status and disable it if necessary:
- Open Settings.
- In chapter "Network and Connections" click "Additional settings" or "More".
- Enter modem mode and disable WLAN access point. If it is disabled, you don't need to do anything else.
Some manufacturers offer users special programs to control smartphones on a computer, but you can establish a simple connection via USB without this software. Utilities from manufacturers are needed not for the banal transfer of photos, but for performing more complex tasks: updating phone software via a computer, flashing the device’s firmware, resetting settings.
The reason that the computer does not see Android via USB may be an incorrectly installed or simply crooked custom firmware. Also, sometimes a factory reset helps, but before doing it, be sure to back up your data as it will delete your data. The problem may disappear even after a normal reboot of the smartphone - keep this in mind.Checking Energy Saving Settings
Windows is trying to save energy so that the same laptops can last longer on battery power. One of the saving factors is the automatic shutdown of USB ports. Sometimes this results in external devices not connecting at all. To check these settings and troubleshoot any deficiencies:
I haven't measured how much the ban on automatic port shutdown affects battery life, but there is no noticeable difference. But problems with connecting external devices such as Android phones are eliminated.
Installing drivers
The first time you connect any device, Windows installs drivers for it. Often this process goes unnoticed and very quickly (as was the case with my second phone), so you may not even know that the smartphone software is on your computer. But it exists, which means it should work correctly.- Connect your phone to your computer.
- Open device Manager. On Windows 10, the corresponding item is in the context menu, called up by right-clicking on “Start”. In earlier versions of Windows, Manager can be found in Control panels in viewing mode "Icons".
- Check all USB controllers. If there is an exclamation mark next to one of them, this indicates that there are problems with the software.
To make sure that it is the phone that is marked in the Manager, disconnect the USB cable. If the problematic controller disappears, then you have found the source of the problem. A smartphone without drivers may also appear in other sections: for example, among other or portable devices.
So, you discovered that something strange is happening with your phone drivers. What to do next?
- Connect your phone so it appears in Device Manager.
- Select it and delete it.
- Update the hardware configuration so that the computer detects the phone again and begins installing drivers.
You don't have to remove the device, just update the driver. Right click on the phone, select tab "Driver" and press "Update". Another option is to install it first and then install it again without touching the device itself.
In the search box, select automatic detection. If you downloaded the phone driver from the official website, you can click "Search this computer" and indicate the path to the downloaded software file.
If you have a Chinese smartphone, then there may be another problem with it - the inability to find a suitable driver on the Internet. They are often posted on forums like 4PDA, but if there is nothing, try installing a universal driver. It's called Universal Adb Driver and is designed to ensure the Android Debug Bridge and PC syncing utilities work properly with Android devices. Universality is not always good, but there is a high probability that in the case of a Chinese phone you will be able to simply access the contents of the memory.Troubleshooting error code 19
If, when you connect your phone, the computer displays a message about the inability to start the device due to incomplete or damaged settings, then you need to check the system registry. But be careful: deleting the wrong entries can cause Windows to stop working.
After removing the setting, restart your computer and try connecting your phone again.
Alternative file transfer methods
If you were unable to resolve the USB connection problem and need to transfer files right away, use one of the alternative methods.- Sync your data via Google Drive. Android requires a Google account to function properly, so you definitely have access to cloud storage. You can transfer files through other services – DropBox, OneDrive. I use Yandex.Disk.
- Transfer files via email, instant messengers or social networks. I often add small files to Documents on VKontakte, and then download them to my computer.
- Install the AirDroid application on your phone and access the memory through a browser on your computer.
You can come up with other options. For example, create an FTP server on your phone or set up a remote connection via TeamViewer. So USB is not the only option. But if a wired connection is not established, it is still worth looking at what the reason is and, if possible, eliminating it.

The computer does not see Android via USB updated: February 7, 2018 by: Sergey
Everyone faces this problem at least once: you connect your smartphone or tablet to your computer via a USB cable, but nothing happens other than charging. The computer does not see the phone or identifies it as an unknown device. The situation is common, but ambiguous, and there are quite a few reasons why it occurs. Today we will figure out what causes such problems and how to deal with them.
Software and hardware failures lead to a situation where the PC does not recognize the mobile device connected to it:
- Lack of device driver in the PC operating system.
- The driver does not match the device model.
- There is no USB driver in the system or it is malfunctioning.
- Connection with a cable that is not suitable for data transmission or is damaged.
- Malfunction of the USB socket (both on the computer and on the phone), group of sockets or USB controller on the PC.
- Failure of any of the computer equipment, blocking by static electricity.
- Error in phone system settings.
- Blocking access to the phone using security programs running on a PC (including if the gadget is infected with a virus).
- The application used to synchronize your phone and PC (if you are using) has crashed.
In case of software problems, the computer, as a rule, does not display the contents of the phone’s memory, but the device charges normally when connected to it. If the problem is due to a physical malfunction, charging most often does not work either, but there are exceptions when only the data lines do not work.
An analysis of the previous situation—what happened before the problem arose—helps outline the range of possible causes. For example:
- You have reinstalled the operating system on your computer or removed some of the drivers (the reason is that the required driver is missing).
- The phone (tablet) was no longer detected after flashing the firmware, cleaning it from viruses, deleting applications, optimizing and other manipulations with the OS (the operating system of the mobile device malfunctioned).
- The device has been subjected to mechanical damage (the USB socket is damaged) or has been repaired (after replacing parts, a driver of a different version is needed or the fault has not been completely eliminated).
- You are using a USB cable that you have never used to connect your phone to a computer before (the cable is only for charging or is damaged), etc.
We quickly determine the culprit of the problem
Tracing a cause-and-effect relationship makes it much easier to localize the problem, but in about half of the cases there is nothing specific that precedes it. If this is the case for you, the following steps will help you determine where the failure occurred - in your mobile device, PC or USB cable.
- Move the cable in the area of the connectors (kinks most often form in these places) and see if the phone (tablet) is detected in the explorer or device manager of the computer. Or connect the devices with another cable that is known to work and is suitable for data transmission.
- Connect your phone to another computer, as well as another mobile device to this PC. If the phone is not detected anywhere, the problem is definitely in it. The same is the case with a computer.
- If the problem seems to be in the computer, check the phone in all USB sockets; perhaps the problem is in one or more of them (for example, only in the front group).
If you conclude that the cable is the source of the problem, simply replace it. What to do in other cases, read on.
The culprit of the failure is the phone. What to do?
If the diagnostics clearly indicate a problem with your mobile device, perform the following steps in order. After each step, check to see if the problem is resolved. If not, move on to the next one.
- Reboot your device.
- Connect your phone to your computer. Once connected, slide down the quick settings menu bar and make sure that the “Connect as” list does not include “charge only,” or “camera” or “media device.” Select the "USB storage" option.
- Open Android system settings (in older versions, “Options”). Go to the "Wireless Networks" section. Turn on modem mode. Or vice versa, if it is on, turn it off. In some editions of Android, this parameter controls not only the modem, but also the connection of the gadget to the PC as a drive.
- Experiment with putting your device into USB debugging mode. Open the “System” and “For Developers” sections in the settings. Uncheck or check the box next to “USB Debugging”.
- Disconnect the phone from the computer, turn it off and remove the battery from it (the phone) (of course, if it is removable). After 5 minutes, replace the battery, turn on the device and try connecting again.
- Remove applications that failed after installation. If the connection doesn't work in a particular sync app, clear its cache. If it doesn’t help, reinstall (both on your mobile device and on your PC) or try using an analogue.
- Scan your device with an antivirus.
- Reset the device's operating system to factory settings.
The culprit of the failure is the computer. What to do?
- Shut down the OS, turn off the PC from the outlet (or press the key on the power supply) and hold down the power button for 15-20 seconds. This will discharge the capacitors and remove stray static charge, which may block detection of the connected device.
- If the phone is not recognized by only one group of USB ports, open the cover of the system unit and make sure that they are connected securely. By the way, normal charging of a mobile device through the port does not mean that the second one is working properly.
- Boot the operating system. Open Device Manager and check if portable devices are listed in the equipment list, and your phone is among them. If it is present, but marked with a black arrow in a circle (disabled), right-click on the line and select the “Enable device” command from the menu.
- If there are unknown devices in the equipment list (indicated by an exclamation point in a yellow triangle), one of them may be the phone. To make sure it is him, disconnect your mobile device from USB. If the unknown device disappears from the list, then that’s it. And the reason for the failure is the lack of the required driver in the system. We will tell you below how to reinstall and where to download the driver for your phone.
- The problem with recognizing connected devices may also be due to boot failure, damaged or missing USB drivers. In this case, the exclamation marks will be in the “USB Controllers” section.
- Reinstalling drivers didn't help? Scan your computer disks with an antivirus and then temporarily disable security programs. By the way, the latter can block access to a mobile device as a storage medium if it contains suspicious or clearly malicious software. So it’s worth checking your phone for viruses too.
- Uninstall the programs whose installation caused the problem, or perform a system restore to a checkpoint created on a day before the problem occurred.
- If, in addition to the phone, the computer does not recognize other devices connected via USB - a mouse, keyboard, printer, flash drives, etc. (whether they are charged or not is not indicative), the source of the failure may be any faulty component of the system unit or something then from the periphery. You can determine the culprit at home by turning off the equipment one by one or replacing it with a known good one.
How to Reinstall Mobile Device Driver and USB on Windows Computer
iPhone
- Connect iPhone to PC.
- Open the folder %CommonProgramW6432%\Apple\Mobile Device Support\Drivers (to avoid typing the command manually, copy it from here, paste it into the address bar of any folder and click the go button). It contains 2 files (out of four) with the .inf extension - usbaapl.inf and usbaapl64.inf.
- Open the context menu of each of these files and run the “Install” command.
- After installation, restart your computer.
Android
Smartphones and tablets for Android, such as Samsung, Xiaomi, Lenovo, Meizu, HTC, etc., as a rule, do not create separate folders for storing their drivers, and they are often not found on official websites so you can just download and reinstall. Therefore, to begin with, you should trust the reinstallation of the drivers already present in the system by Windows itself.
How to do it:
- Open the context menu of the problematic device in Device Manager. Select the "Update Driver" option.
- In the next window, first select automatic search for updates. If Windows does not find anything suitable, check the second item - installing and searching for drivers manually.
- Next, click “Select from the list available on your computer.” A new window will display all mobile device drivers that are already installed on the PC.
- To narrow your search, in the “Select a driver for this device” section, check “Compatible only.” Check the one that best suits your request (if there is more than one item in the list) and click “Next” to proceed to the installation.
For the driver to work correctly, restart your computer.
If reinstalling the driver already installed in the system did not help, you will have to look for something else on the Internet (with the risk of downloading a virus instead of the one you are looking for), so download them only from reliable and trusted sites, like w3bsit3-dns.com, and check with an antivirus before installation.
Drivers for the most common models of mobile gadgets are also collected in the “USB Drivers for Android” application, which is available for free download on Google Play.
USB drivers for Windows can usually be easily found on the websites of laptop or desktop PC motherboard manufacturers. Sometimes they are included in the chipset driver.
If the phone is not recognized in firmware mode
The fact that the computer and phone do not see each other in fastboot mode is indicated by the message “Waiting for device” that appears in the firmware program. Most often, this error occurs due to the lack of a mobile device driver in the system, so first of all, do what is written above - reinstall the driver or download and install it again.
If it doesn't help:
- Make sure that you follow the instructions for working with the firmware installation program exactly and that it is running as an administrator.
- Check if USB debugging is enabled on your smartphone (if not, enable it), and the device itself is in bootloader mode. If this mode is blocked, find instructions online for unlocking the bootloader specifically for your device model.
- Connect the phone to the rear USB socket as short as possible and with a known good cable, without using any adapters or hubs.
- Your phone may not support USB 3 (blue socket), so only connect it to USB 2.0 (black sockets).
- Install all released Windows updates on your computer.
If the problem persists even after doing this, try flashing the phone on another PC. And better - with a different version of the operating system.
When the problem is a broken physical interface
It is advisable not to use faulty physical interfaces, especially on a mobile gadget, at all (do not load them with current to avoid worsening the breakdown), even if the phone or tablet retains the ability to charge through them. You can organize content transfer either wirelessly (Wi-Fi, bluetooth) or through cloud services that are available on both devices. In particular, iTunes and iCloud for Apple technology, Google Drive, Yandex Disk, Dropbox, Microsoft OneDrive and many others - for everyone.
Cloud services are convenient to use for transferring photos, videos, music, documents and other types of files. To synchronize contacts on Android and PC, the capabilities of Gmail are sufficient. And to control your phone directly from your computer, you can install an application like MyPhoneExplorer (consists of 2 parts - for the phone and for the PC), which supports both wired and wireless connections of devices without requiring driver installation. Very comfortably.
In short, there is always a way out and it is often much simpler than it seems at first glance.
