The computer does not see the nokia rm 986. What should I do if the Nokia phone does not see the SIM (SIM) card? Connecting via infrared

Many users, when trying to connect their phone to a computer using a USB cable, are faced with the fact that the computer does not recognize the connected gadget. The connected device is charging, while there is no access to the smartphone itself and its internal content. I also encountered this synchronization problem, and in this article I will tell you why the computer does not see the phone via USB, and I will also share various methods for solving this issue.

The whole complex of reasons for the problem that the PC does not see the smartphone through the USB cable, I would divide into hardware and software, and below I will list each of them, in parallel providing instructions for fixing it. But before using the methods I have indicated, try restarting your computer and smartphone - this does not help as rarely as it seems. This problem mainly occurs with Samsung, Lenovo, HTC, LG, and Fly devices.

So why does the computer not see the phone via USB, but is charging - hardware reasons

1. Damaged cableUSB. It often happens that the cause of this dysfunction is damage to the USB cable itself. Cables from little-known or "non-name" manufacturers do not have a large margin of safety, and can fail in just a couple of months from the start of operation, and as a result, the computer will not detect the connected phone.

In addition, even the most reliable cables from global brands are prone to stochastic damage - they can be accidentally damaged during use, pets can chew them or spoil them by children. Therefore, first of all, inspect your USB cable for the possibility of mechanical damage, and, if the external safety of the cable, try using it to connect your device to another computer. If the device is not recognized on another PC, try replacing the cord.

2. Damaged portUSBon the computer. The USB ports used in the computer are also prone to various mechanical damage, including damage to the USB controller, as well as south bridge motherboard. Try plugging the cable into another USB connector, if this did not help fix the connection of the phone to the PC, follow the further advice.

3. Damaged socket for connecting the cable on the phone. Has the smartphone jack been exposed to water or damaged? If yes, then it needs to be replaced.

4. Try removing the battery. According to some users who also had a problem with the fact that the computer did not see the phone through U-ES-BI, removing the battery from the smartphone helped.

Turn off the battery, remove the battery from it for a few seconds, then put it back, and turn your device back on.

If nothing helps you fix this problem then describe your situation. What have you already done and what is happening to your Android device at USB connection gadget to the PC in the comments, I will try to help not only me, but also everyone who has encountered this problem.

The computer does not see the phone via USB - software reasons

After describing the hardware reasons, we list the main program reasons if your computer still does not recognize cellular telephone connected with via USB cable, follow the instructions below.

1. Working with the settings.We go into the settings of our device, select "Memory" there, click on the three dots at the top (Properties), select "USB connection to a computer" and put a tick in front of "Media device" (" USB stick"). If you have a checkmark next to USB usage as a modem - remove it.

The service must be enabled on the PC. windows update(for downloading phone drivers) and a new device discovery service. Don't forget to unlock your phone when connected to your computer, this is important.

If you are a conservative and have Windows XP installed, download the Media Transfer Protocol (MTP) for XP from the Microsoft website and install it on your computer.

2. If your drivers have crashedUSB-ports, the computer may not see the phone.When drivers for USB ports malfunction, the latter simply stop working. To fix this problem install USB drivers from the "native" disk with drivers to the motherboard of your PC, or download the latest drivers from the website of the motherboard manufacturer.

Also, due to any reason, power can be turned off for a number of ports.

3. Device drivers have crashed. Go to the "Device Manager" and see if there is a question or exclamation mark in the "Portable devices" item.

Check if your device is there and make sure it works fine by right-clicking on it and clicking "Properties". If it's not there, or if you're in doubt, uninstall the driver, disconnect your phone from the computer, and then turn it back on, and let the system install the driver again. This can help solve the problem that the smartphone does not connect via USB to the computer.

It will also not be superfluous to enter the website of the manufacturer of your smartphone and download the latest drivers for it on your PC (for example, there is special software for Samsung Samsung Kies).

4. Install the updateKB3010081 (KB3099229). For owners of Windows 10, you may need to install update KB3010081, which is responsible for working with Windows media player. This player is directly related to the normal operation of the MTP (Media Transfer Protocol) service, so download and install these updates.

Also, a common cause may be an unreliable assembly of the OS itself on the PC. Only rearranging Windows will help here. working version.

5. Custom firmware is not working. The desire of many fans to play around with firmware for their Android device can do them a disservice in the form of a device failure to work normally with a computer. Try to restore the standard firmware or restore from a backup (if any).

There are no drivers for the phone on the computer

Although, usually, a computer with the latest OS detects and sees a smartphone via USB without problems, reverse cases can also be observed. Try to search for a driver for your smartphone on the net, sometimes a driver for similar models of this brand may come up.

The phone may not be detected by the computer due to viruses

Trite, but all sorts virus programs may block external mobile devices. Try checking your computer with Dr. Web CureIt!, in some cases it can help.

If the problem of detecting a mobile device by a computer is not resolved, reset the settings

If until now, your computer does not see the phone via USB, resetting the smartphone using Hard reset. Go to your phone settings, select the menu item " Backup”, and in it select “Reset data”.

But I immediately warn you that you will lose your files and settings located in internal memory phone (the files on the SD card will remain intact), so this item should be used only as a last resort!

Conclusion

As you can see, problems with the lack of visibility of the connected phone on the PC can be both software and hardware in nature, and there are a considerable number of such problematic factors. I would advise you to first pay attention to the probable mechanical damage in the cable and device, and only then switch to software methods.

In many cases, a simple reboot of the smartphone (temporary removal of the battery) can help, as well as working with the phone's USB connection settings. If all of the above does not help and the computer does not see the phone via USB, but is charging, then you may need to contact a qualified service center.

P.S. For lovers of visual demonstrations, I present a video on the subject:

If you are in a situation, when the computer does not see the phone throughUSB, then you have come to the right place - in this article we will talk about how to solve this problem.

Note: before proceeding to solve the problem, you must also decide when the computer stopped seeing the connected throughUSBtelephone. Did it happen suddenly and unexpectedly, or after certain manipulations with the phone or computer, etc. All of this together will help you sort out the problem much faster.USB .

If you have iPhone, most likely, to solve the problem with the connection will help . If you have a phone Nokia Lumia or Microsoft Lumia, there will definitely not be any problems with connecting to a computer (at least, software ones), since the manufacturer has taken care of the perfect compatibility of devices on Windows whether desktop or mobile version operating system.

Reasons why the computer does not see the phone connected viaUSB

Before we begin to solve this problem, it is necessary to understand the reasons why the computer may not see the mobile phone that is connected to it. So, maybe it's about:

1. Damaged USB cable.

1. The USB port on the phone is damaged.

1. The computer does not have the software required to work correctly with the mobile device.

1. The USB port directly on the PC itself does not work or is disabled.

1. Another connection mode is selected on the phone, for example, " Charging only».

So, in the case of a damaged connector or cable, the solution to the problem suggests itself - replacing the cable or repairing that very connector.

If the software is not available, it must be installed. To do this, use the driver disk that comes with the phone. If it is not there, you need to visit the website of the manufacturer of the mobile device and find the appropriate software there. Alternatively, you can visit the most popular resource in Runet dedicated to mobile devices: 4 PDA and use the local search by topic by entering your phone model.

If the problem is with the USB port directly in the personal computer itself, the solution to the problem is described in .

What to do if the computer isWindows XP does not see the connectedUSB can't see the phone?

If you have just purchased a mobile device, or if you are connecting it to a personal computer or laptop to Windows XP There are two options for solving the problem:

• Install more new version operating system.

This, of course, is more logical in our advanced time, but not as simple as we would like.

• Install the protocol on the computer MTP, which can be downloaded from the official website Microsoft on this link.

After installing this software and restarting your computer, you will most likely be able to connect phone to pcUSB.

Note: big advantage of newer versions OS Windows , in particularWindows 10 , is the fact that operating system automatically installs the software necessary for the operation of a particular device.

For six months of work with OS Windows 10 personally, I have never had problems with drivers and other software, I freely connected and started working even with devices that were not supportedWindows 8 / 8.1

The computer does not see the phone throughUSB due to incorrect connection mode

Note: often, devices that are locked graphic key, are not detected by the computer until the user unlocks the screen.

After connecting your phone to a computer via USB, make sure that the mobile device reports the corresponding operation in the notification area. It should indicate which device the phone is connected to.

Most mobile devices have three or four connection modes:

• Only charging.

• Data storage / Media device.

• Camera (PTP).

• USB modem.

The correct connection mode, in which the computer must recognize the phone and allow it to work with it, is data storage.

Mode " Camera» limits actions and functionality. What means " Charging only”, you probably understand. In the case of tethering mode, you will also not be able to access mobile device.

Most likely, all the above manipulations have already helped you deal with the problem, why the computer does not see the phone throughUSB and solve it. If the essence of the problem is of a physical nature, that is, damage to the cable or phone connector, or you simply don’t want to figure out what’s wrong, and you need to get access to the mobile device from the computer, there are other ways to exchange files between devices:

• Data synchronization via cloud storage. For example, Google Drive, One Drive, dropbox, Yandex Disk or CloudMail. Ru about which we wrote .

• Using programs by type .

This can be finished, the connection problem is solved. If you have any questions, leave them in the comments.

Modern smartphones on Android users regularly connect to a laptop or PC to reset music, photos or other necessary files. In some situations, the computer does not detect the phone via USB, which makes it very difficult to work with it. There is a certain list of reasons that prevent the device from being recognized.

The computer does not recognize the phone via USB - reasons

All possible variants of problems faced by users can be divided into software or hardware. In the first option, the problem is in the settings, drivers or computer system, in the second - in the cable, usb port smartphone or laptop. Almost all problems can be fixed, but before you try to fix the connection of your phone to a computer via USB, try restarting your PC and device. This simple procedure often helps, especially with models of devices from Lenovo (Lenovo), Samsung (Samsung), HTC, FLY, LG, Nokia (Nokia), Huawei (Huawei), Asus (Asus).

The phone does not connect via USB to the computer, but it charges

A very common problem with devices is when the phone is not displayed in the computer via USB, but the battery charge indicator is on. The smartphone responds to the connection, but the system does not want to display it. To determine the cause of the failure, you can perform the following actions:

1. Move the power cord to a different port on the laptop. Now most models are already equipped with version 3.0 connectors (it is blue), but you need to use 2.0. On stationary versions, the connection should be made from the rear side of the case, and not from the front panel.
2. Try a different cord if the sockets match. This will help you troubleshoot the cable. If one of the cores of the twisted pair is broken, then the smartphone can continue to charge, but not be detected.
3. Inspect the socket of the device, if there is any debris or dirt inside that breaks the connection of the contacts and makes it difficult to find the device.
4. Try connecting the machine to another PC. If it is defined there, folders with documents are visible, and they can be opened, then the problem is definitely in your system: there are no drivers, a virus, the power on the laptop is not configured correctly. This problem will be described in more detail below.

The computer stopped seeing the phone via USB

Often there is a situation when the device was previously detected, but for some reason it suddenly stopped. Common cause why the computer does not see the phone via USB - the port drivers have crashed. Due to software failures, the latter cease to function correctly, are not able to find any connected devices. In this case, you do not need to reboot the device. You need to do the following:

1. Find the "native" disk for the motherboard. Everything must be in the set. system files for correct operation of USB ports.
2. If the disk is lost, find the developer's website on the Internet. Manufacturers, as a rule, lay out all the necessary software for free access.
3. Reinstall drivers.

After the PC has finished installing the files, you need to restart the computer. Only at this point is it time to check if the system can recognize the device. If these steps did not help, make additional settings:

1. In the control panel, go to the "Power" section.
2. Select "Setting up a power plan" (for laptops).
3. Click "Change advanced settings..."
4. From the list, select "USB Settings", click the plus sign.
5. Then expand the "Pause USB Port Option" section.
6. Set "Disabled" for battery operation, mains operation.
7. Click "Apply" and "OK".

In addition to problems with port drivers, files for the Android device itself may disappear. To check this, you should open the device manager, find out if there is an exclamation icon in the "Portable devices" section. Check the list for your phone. If it is not there or there is a warning sign, you should do the following:

• open the device and click "Uninstall driver";
• turn off your mobile device;
• reconnect it;
• wait until the system installs the connected device again.

The computer does not find the phone via USB

Sometimes the situation is such that the laptop does not initially find the device. If the reason is not a broken cord or port, then you should carefully check why the computer does not see the phone via USB. The causes of problems can be such moments:

1. Android system settings. Modern mobile devices have several connection options: only charging, storage, modem. By default, most of them are set to the first value in the list. As a result, the device is charging, but not displayed by the system. As a rule, the top menu of the device, when connected, offers to change the type of connection, you just need to select the required parameter. If this does not happen automatically, you need to go along the following path: Settings -> Memory -> Properties. Here you should set the required type of connection.
2. Sometimes a smartphone is used as a modem, which does not recognize it as a drive. Disable this option via settings.
3. Turn on Windows Update, which will allow the PC to download the latest, up-to-date drivers for all connected devices. When connecting, do not forget to unlock your mobile device.
4. When selling together with a smartphone, a disk is provided on which there is a program for connecting the phone to a computer via USB. Use it to discover the device.

The computer does not recognize the phone via USB - viruses

Malicious programs that have entered a PC system can behave in completely different ways. Sometimes they become the reason why the computer still does not see the phone via USB. Viral scripts disrupt work different devices, remove drivers, block data transfer. The risk of infecting a smartphone is extremely low, because viruses for Android are extremely rare. However, to protect yourself from infection, you should check Windows using specialized programs:

• Dr. Web;
• antivirus kaspersky;
• Malwarebyte.

What to do if the phone does not connect to the computer via USB

If your system, after all the above steps, still does not see the device, but you are 100% sure that the problem is not in the USB cable or socket, the device was previously detected, there is only one way out - hard reset. A hard reset will erase all data from the internal memory of the phone and reset it to factory settings. This will eliminate the possibility of a software failure on the part of the mobile phone.

All data that you store on the SD card or cloud services will remain unharmed. This option should be used in extreme cases - provided that all other methods did not give the desired result, and you are sure that the problem is in the device settings, but not the PC. For each model, be it Samsung or NTS, the manufacturer has programmed hardware buttons that make it possible to perform a hard reset. You can also enable it from the settings if the device turns on and you have access to them.

What to do if Nokia does not catch the network? First you need to establish the cause, and the cause can be several factors. First, let's try to determine: this is a problem in network support or directly on the phone itself.

To begin with, you need to make sure of this - is there at least one division of network reception? Try changing the settings. To do this, go to the "SETTINGS" submenu, select the "AUTOMATIC" search mode. When these steps have no effect, you can try to select your carrier's network manually. The problem may be related to your SIM card: either it has expired, or it is faulty.

It happens that the Nokia device does not catch the network only in some places (for example, the basement floors of a building, underground parking, houses with concrete walls). Then, most likely, your operator mobile communications has poor radio coverage in the area. You can try to solve this problem by calling technical support mobile operator. Otherwise, try reconnecting by going to a window or going out into an open area.

You can test the phone by replacing the SIM card with a similar one, only from a different operator. If, still, Nokia phone does not see the network, then, often, the problem lies precisely in the malfunction of the mobile device. There are many reasons for the non-working state - ranging from damage to the antenna contacts and ending with a failure of the mobile phone software.

The first, most common cause may be moisture getting into your phone. If you notice water droplets inside the case, you need to remove the battery and dry the components thoroughly, after which you need to assemble the mobile phone and try to resume communication. If your Nokia still does not catch the network, it may have caused the contacts to close and disabled the radio elements. There is nothing to do on your own, therefore, to resume the operation of the device, it is advisable to visit a service center.

The second reason is the fall of the device or a strong blow, as a result of which the telephone antenna was damaged. It will not be possible to solve such a problem without the intervention of a specialist of the SC.

The Nokia phone does not see the network even if the software has been broken. Then, resume work mobile phone will be able to flash it, which must be done at the service center.

Hello, my phone stops reading the SIM card from time to time and does not see contacts, call log, writes that the list is not yet ready. It used to happen once a month, but more often than not. After starting the phone, it lasts for a while, but I don’t know how much. Although they don’t make diagnoses in absentia, but what can it be and is the phone worth repairing? I mean the financial side of the issue.

Good afternoon Arthur. Looks like a problem with software, repairs can cost 1300.

How much does a flashing cost

Hello Roman. Firmware costs 1300.

Sincerely, GrandFon Administrator.

What to do if the Nokia phone does not see the SIM (SIM) card? In most cases, Nokia phones do not see the SIM card due to a failed SIM card filter. This may be due to water or a blow, but there are also cases when this filter is close to the card capture reader and people themselves chip off this glass by careless handling. In general, the situation is not pleasant but easily fixable) This filter can be replaced with jumpers. How to do it?

I will try to explain in pictures, thus it will be an example of how to read the diagrams. Let's start. We download the scheme of your model from the Internet. I chose nokia N70 as an example. Open the chart and scroll to the bottom. There we should see a picture with the exact location of the elements on the board. We find this picture and on it we find our card reader for the SIM card. On it we see its number in the diagram. In my case it is x2700. Under this number, my card capture reader is indicated on the diagram. Now you need to find it on the diagram in order to see where the tracks go from this sim receiver. We press the combination ctrl + F, thereby calling the quick search function in the acrobat. And in the search bar, write the number of the part of interest. On this moment I enter x2700 and press search. The search gives me just such a picture, in which I see that the contacts of the sim go to a microcircuit (in the people of glass) which serves as a static filter. This is where most of your problems lie. It remains to find it on the board and replace it with jumpers. We look at what number she was assigned in this scheme. Again, in my case, this is r2700. Now we do the search as before. In the search, we now enter r2700 our glass and see this picture

What does this picture mean? If you look closely, then near the number of our glass we see the number I6. This is the number by which you can find it on the parts diagram. We look at the layout of the parts and look for the square of the intersection of I and 6. So we found this filter. The smallest is left. remove it and install jumpers. You can remove it either with a hairdryer or a 60-watt soldering iron. I prefer the second method as it is faster and easier. We take a drop of flux and smear around this microcircuit. We take a more powerful soldering iron and collect a drop of tin on the tip. Now with one hand we hold this glass with tweezers, and with the second drop of tin on the soldering iron we warm it up. In this way, it is removed without problems literally immediately. Having removed it, we will see 8 dimes. 6 of them we will need to close. I already wrote in a previous article. We take the board and unfold it so that the empty space is in the lower right corner in relation to you. Like on a picture. Well, then everything is as shown.

This filter is on most nokia phones. But of course there are some who SIM contacts go immediately under the processor, but more on that some other time.
