Where is the reset? Clean installation of Windows 10 using the Refresh Windows Tool. Main types of problems

Every Android smartphone has a recovery mode that allows you to erase all data from the internal memory of the smartphone and return it to factory settings. However, this method is not always effective.

If you were unable to perform a hard reset (aka factory reset) through Recovery mode, Google has provided a special command line utility, Android Debug Bridge, to access your mobile device and execute certain commands through your computer. So you can do a factory reset via your computer.

We would like to point out that ADB commands to reset settings via computer are intended for advanced users. But, if you read our instructions carefully, you should not have any problems.

Instructions: How to reset settings via computer?

Step 1

Go to the Android developers website and download the Android System Development Kit. Right-click on the ZIP archive and select "Extract All". Click the Browse button and select the C:\Program Files directory.

Step 2

Go to the folder where the files were extracted and press "F2" to rename it. Give the folder a simple name, such as "AndroidADT".

Step 3

Right-click on "My Computer" and select "Properties". Click on the "Advanced System Settings" option and in the "Advanced" window, click on the "Environment Variables" button.

Step 4

In the System Variables window, select the Path option and click the Edit button. When the window for editing system variables opens, scroll to the very end and write the path to the archive that you unpacked earlier (“;C:\Program Files\AndroidADT\sdk\platform-tools\”) (without quotes). Make sure you add a semicolon at the beginning of the path. Click "OK" to save your changes.

Step 5

Hover over the top right corner of the screen and click the Search button. Type “cmd” in the search field and click on the program icon in the search results to launch a command prompt window.

Step 6

Turn on your smartphone and connect it to the computer's USB port. Write "adb shell" and press "Enter". When ADB connects to the mobile device, write “--wipe_data” and press “Enter”. Your phone will reboot into recovery mode and automatically reset to factory settings.

Now you know how to reset settings via a computer.

Users of Android devices at some point experience freezing, frequent errors, and sudden termination of a number of applications. This is due to the accumulation of various unnecessary and residual files in memory that slow down the operation of the OS. Any repair always includes resetting Android settings to factory settings, i.e. deleting all folders with files and applications (the so-called Hard Reset). How to do it yourself?

Before you begin work on deleting all unnecessary files and resetting the system, you should copy all important information to a memory card or transfer it to another device.

After resetting the settings will disappear forever:

  • all installed applications;
  • contacts;
  • downloaded and received files (photos, videos and music);
  • installed settings (alarm clock, reminders);
  • accounts and passwords.

At the same time, updates to the operating system itself and the software version remain and are not “rolled back” to the original ones. In addition to saving important information, it is necessary to delete your Google account and clear your passwords. Otherwise, when turned on, the device will ask you to log in to your account.

You can reset your Android phone to factory settings through the settings menu, if the system allows it (some viruses block access to them).

To do this you need:

  1. Open “Settings” – “Backup and reset”. On some devices, this feature is hidden under Backup & Reset, Privacy, or Accounts.
  2. Find the item “Reset settings (data)” and click on it.
  3. The system will show a notification that all files and accounts have been deleted.
  4. You must select “Reset settings”.
  5. The operating system will issue a second request, you need to confirm it.

The system will begin deleting all unnecessary files and reboot the device after the operation is completed. You should charge the device to 100% in advance, because if it runs out of charge during the removal process, unpleasant difficulties will arise that you are unlikely to be able to solve on your own.

Via phone

You can also reset all settings using the smartphone itself, that is, by using its hardware buttons. To restart your smartphone, you need to turn it off completely, and then simultaneously press several buttons: “Power” and two volume buttons (“up or down”). The phone will begin to restart and reset its settings.

Also, some developers place a special button to update the system. It is very small and is most often located in the recess next to the power button. To start the operation, press it with a needle or pencil.

Using the Recovery keys

This method is suitable for devices that freeze at the startup stage and do not respond to touches on the screen. It is also relevant for users who have forgotten their login passwords.

To reset, you need to press a certain key combination, go to Recovery mode (factory software) and from there start system recovery.

Resetting Android via “Recovery” with the gadget turned off occurs in this way:

  1. Press a combination of buttons (it is different for each model).
  2. Go to Recovery mode.
  3. Go to Wipe data – factory reset.
  4. Agree if requested again.
  5. Wait for the operation to complete.
  6. Reboot the gadget by clicking on Reboot System.

Each company that produces electronic gadgets assigns its own combinations of hardware keys that help users solve the problem.

The device models and their hardware keys are listed below:

  1. Lenovo, Aser, Asus, Huawei: “Volume down + reset.”
  2. LG: “Volume Down + Power.” Press and hold for 10 seconds, wait for the logo to appear, release the keys for 1 second and press again until you enter Recovery mode.
  3. Samsung: “Home + Power + Volume Up.”
  4. Sony: “Home + Volume Up + Power.”

If your device does not respond to touches on the screen, use the Volume keys and the Power or Home key to select menu items.

Using a computer

If you can’t reset the settings using traditional methods, you can try to do it through your computer by first downloading the Android System Development Kit program from the developers’ website.

After downloading the file you should:

  1. Enable USB Debugging mode on the device: “Settings” – “For Developers” – “USB Settings” or “Settings” – “General” – “About Phone” – “General” – “Information Programs”.
  2. Check the boxes for Tools and USB Drivers.
  3. Install drivers for the device on your PC and connect it via USB.
  4. Open the command line and write in it “C:\Users\Username\AppData\Local\Android\Android-SDK\platform tools
  5. Enter ADB reboot into recovery.
  6. Wait for the system to restart.

After this, you can enter a new password and access the menu settings.

Reset by service code

There is another simple and quick way to reset the system - using a special service code.

To do this you need:

  1. Open the phone keypad (in the calls section) or “Emergency call”.
  2. Enter the reset code: *2767*3855# or *#*#7780#*#* or *#*#7378423#*#*.
  3. After entering the code without asking for confirmation, the device will begin to reset.

Since this feature makes accessing the phone too easy, and in case of theft it can play into the hands of thieves, not all manufacturers allow the system to be restarted this way.

What is it for

In what cases is it necessary to restart the system and roll it back to its factory state?

This is usually necessary to resolve system errors, as well as:

  • before selling the device;
  • with constant system freezes and numerous failures;
  • immediately after the software update.

If you cannot reset the settings yourself, then it is best to contact a service center for help. Because you can inadvertently delete important system files and thereby harm the operation of the device.

In some situations, Android users want to erase all data from their smartphones or tablets and restore them to default. This article contains step-by-step instructions that will show you how to reset your Android and get an “empty” device.

Restoring a device to factory settings means that after this process the device returns to the state it was in immediately after purchase. This erases your Google account information, saved app settings, and files (photos, videos, and audio tracks) contained on internal or removable media.

The following four steps will help you erase all your sensitive data from Android and restore your gadget to factory settings.

Warning

Before you begin this process, you must back up all your personal data that you later want to transfer to a new device. Otherwise, your information will be lost forever. To back up your personal data to your computer, connect the device using a USB drive and save all data to a folder on your PC's hard drive. You can also transfer your personal information and application data to Google's servers, but this is a little more complicated.

Step-by-step instruction

Despite the fact that different platform distributions have differences, resetting settings on Android is similar, regardless of your software version.

1) To begin the process of deleting data on your smartphone or tablet, first tap the Menu key to open a range of available options on the screen.

3) In the “Privacy Settings” menu, click on the “Factory data reset” option, and on the next menu, choose whether you want to reset your Android and erase all data on the device, information on your external MicroSD memory card, or all media by filling in the appropriate boxes. Once you have made the desired selection, you must confirm it by pressing "Reset Phone".

4) You will be asked to confirm again that you are indeed ready to reset your device to factory settings. Click the "Remove All" button to complete the process. The device will perform a full reset on Android and after rebooting your tablet or smartphone, you will see that it is ready to work again.

Please note that the process of deleting all stored data may take 10 minutes or more to complete, depending on how much information is stored on the device and/or memory card.

Features of different versions

Speaking about how settings are reset on Android 40, you should take into account some menu features. In gadgets with this version of the operating system, returning to factory settings has its own section in the Settings menu. Go to the menu in the same way as mentioned in the previous steps and scroll down to the options about backup and data reset. Resetting settings on Android 41 occurs in a similar way.

They do not always take a prudent approach to downloading applications to a device - many, admiring the abundance of free software in the AppStore, install everything without thinking about the usefulness of the programs. It is the lack of free memory that is usually the reason why the iPhone begins to perform worse: for example, it freezes or reboots spontaneously. If such “symptoms” appear, then it’s time to “clean” the device’s memory - this can be done by resetting the iPhone to factory settings.

Before resetting your iPhone to factory settings, you should back up the data stored on your phone using iTunes– then, if necessary, important information can be restored. You can create a backup in two ways:

Step 1. In the AppStore context menu, follow the path “ File» — « Devices» — « Create a backup».

Step 2. Click the device icon in the top panel and in the “ Review» click « Create a copy now».

It will not be possible to “resurrect” all data using a backup copy - only the following will be available:

  • Contacts.
  • Application Contents " Notes».
  • Photos.
  • Messages and call history.
  • Phone settings and network settings.

Games, applications and music will not be restored.

Reset iPhone via Settings

You can reset the settings on your iPhone without connecting the gadget to the computer at all - you need to do this:

Step 1. Go to " Settings" and select the section " Basic».

Step 2. Scroll to the end and select the subsection " Reset».

You will see that the device offers several reset options, including:

  • Reset settings on iPhone. With such an operation, all personal information that the user stored on the gadget will remain in place. But, say, alarm clocks and standard application settings will be reset. This short-term operation (the reset lasts no more than 1 minute) can help with periodic iPhone freezes.
  • Erase content and settings. This type of reset is useful when an Apple user wants to give away or sell a used iPhone. The buyer receives a completely “clean” gadget without traces of prior use - including de-authorization Apple ID. This operation is longer and takes about a couple of minutes (depending on how “cluttered” the memory is).
  • Reset network settings. This operation helps if, after replacing the SIM, the gadget cannot find the network of a new service provider and access the Internet via 3G. Personal information will definitely not be affected by such a reset.

Before resetting your iPhone, pay attention to these “safety rules”:

  • Before resetting (especially the second, longest type), recharge the gadget to at least 25-30%. If the iPhone “dies” while erasing data, most likely it will have to be restored through iTunes and cable.
  • iPhone with jailbreak (eg. Pangu) as a result of erasing the content, it will end up in “eternal apple mode”. Again, you will need to restore through iTunes with preliminary introduction of the gadget into DFU mode or Recovery Mode.

How to reset an iPhone via iTunes?

If necessary, reset the settings via iTunes First of all, you should disable the " Find iPhone"(if it is activated). To deactivate on your device, follow the path “ Settings» — « iCloud» — « Find iPhone" and turn the toggle switch to the "OFF" state. Then connect the gadget with a USB cable to the PC and follow these simple instructions:

Step 1. Click on the " Device", and you will find yourself in the section " Review».

Step 2. Click the button Restore iPhone..."

Step 3. In the window that appears, click " Restore» again - this way you confirm the request.

After that iTunes It will download the software to the gadget itself and return the iPhone to its original settings. When resetting the settings in this way, contacts, SMS, calendars, alarm clocks and notes will not be affected, but you will have to say goodbye to multimedia files.

Completely reset settings via Hard Reset

Reset via Hard Reset needed in such a situation: the user has forgotten the security password and cannot deactivate " Find iPhone" - the enabled function, in turn, prevents the settings from being restored through iTunes in a softer way.

It’s not for nothing that such an operation is called “hard” ( Hard) – resetting may result in all personal data being lost. Therefore, contact Hard Reset It is recommended only after other options have already been tried and were unsuccessful.

Recovery via Hard Reset done like this:

Step 1. Connect the gadget to your PC and launch iTunes normally.

Step 2. Enter your smartphone into DFU mode in the following way: simultaneously hold down the " Home" and the power button and count to 10. Then release the " Power" and continue to hold " Home» until the characteristic sound of connection in iTunes. After entering the gadget into DFU mode, there is no point in looking at its screen - it will be just black, without icons and images.

Step 3. Talk to iTunes, and you will see that the window has changed and only one button remains available - “ Restore iPhone..." You need to press it.

You will have to wait quite a long time for the initial settings to be restored - about 10 minutes. When the reset is complete, the user will have to choose one of two options: reactivate the gadget or try to return the deleted data through a backup copy to iTunes. To implement the second option, you need to go to the section “ Review» device and press the button « Restore from copy».

Conclusion

Unfortunately, the problems of smartphone users are not limited to gadget freezes - quite often, owners of even such secure devices as the iPhone become victims of fraud: attackers find out the security password, change it remotely and begin blackmail and extortion - your humble servant has also found himself in this situation. There is no question of transferring money - the blackmail will never end - but a simple reset to factory settings via iTunes will help leave intruders “out of their depth.” The main thing is not to neglect such an opportunity as creating backup copies: then, even after a “hard” reset, you will be able to restore important data.

Smartphones and tablets running the Android operating system have decent functionality and allow you to solve a variety of tasks. They run various applications, store photos, videos and other data. Sometimes there is a need to get rid of everything that is stored in the system at once. Manually deleting data is too time-consuming, so it is easier to return the device to its original state by instantly wiping it.

How to factory reset Android OS? There are many ways, which we will talk about in our review. Why do you need to reset the operating system and the entire device to its factory state? This is done in the following cases:

  • When transferring or selling the device to another user;
  • If the Android operating system does not work correctly;
  • If it is impossible to start the operating system;
  • With numerous errors in the operation of programs and the OS.

The result is a complete wipe of the Android device to its original state.

Reset via main menu

Do you want to sell a smartphone or tablet? Do you need to get rid of errors in the functioning of your operating system and applications? Then we will tell you how to reset Android to factory settings and clear the device of installed programs and data in memory. The easiest way to perform a reset is to go to the main menu, select “Settings”, select “Activation and reset”, click on the “Data reset” line.

What happens next?

Android Engineering Codes - Factory Reset

As a result of various errors, some menu items may not be available. And it will be impossible to reset Android to factory settings. What to do in this case? The easiest way is to use one of the engineering commands available in all versions of the Android operating system and on all devices. The command *2767*3855# will help you perform a full reset - she is dialed in a regular dialing program.

If for some reason the command did not work, you can use another command - *#*#7780#*#*. Just like the previous command, it will help you perform a Hard Reset (resetting Android to its factory state. If this does not help, try typing the third command - *#*#7378423#*#*. After the reboot, you will receive a clean device returned to original factory condition.

Do not use commands whose purpose you do not know, as this may lead to the loss of functionality of your device.

Reset via Recovery mode

The Android operating system may become so damaged that it becomes impossible to start. A typical sign of damage is the device loading endlessly. The only way to bring the device back to life is a Hard Reset (master reset) through Recovery mode. To access this mode, use the following combinations:

  • “Power on” and “Volume down”;
  • “Power on” and “Volume up”;
  • “Power”, “Home” and one of the volume keys;
  • "Power" and both volume buttons.

You need to press the buttons when you turn on your smartphone or tablet. For some models, additional actions are performed by pressing certain buttons after turning on the device using the above combinations. Thus, in order to restore factory settings on Android, you need to look for a key combination that allows you to enter Recovery mode on your device (usually this mode is used to flash Android devices).

Next, select “wipe data/factory reset” and wait until the return to factory settings is completed. Please note that all data on your phone will be deleted. Therefore, you should not neglect creating backup copies to avoid losing this data.

Do not touch other items in the engineering menu or in Recovery mode under any circumstances - this can lead to the most unexpected consequences, including the complete loss of functionality of the device and the impossibility of its further recovery.
