How to reset your phone to factory settings: all working methods

When might a factory reset be necessary?

Resetting to factory configuration on Android is carried out for two reasons:

Selling or exchanging a gadget. To save time and not delete information in separate files, it is better to do a full reset;
Decreased performance. Over time, performance in smartphones or tablets begins to decline. This occurs when the operating time decreases and overheating occurs. In frequent cases, a huge amount of software garbage accumulates in system folders.

Depending on the functional and design features of the devices, there are many methods for resetting to the original state. The procedure can be performed using standard tools or specialized programs.

To save information, you can use Titanium Backup, here is information about the possibility of data recovery after a hard reset Tele2 Mini 1.1.

Resetting settings on Android through the gadget menu

The obvious way to complete the task is to use the smartphone menu. The user does not have to use applications or button combinations. If your gadget has one of the latest versions of Android OS installed, you will need to do the following:

Unlock your smartphone;
Expand Settings Center;
Use the recovery or reset block. There are OS shells with a different name;
At the next stage, a page will open in which you need to use the reset button;
To prevent data deletion, it is recommended to create a backup copy in a timely manner.

Attention! When the user presses the button, the device will roll back to its original state. It is strictly forbidden to remove the battery at this moment or resort to an emergency reboot of the OS.

How the card is formatted

In devices that support the Android OS, there are frequent situations where difficulties arise with a removable memory card. When problems appear in the file system, Android OS will suggest formatting. In addition, the need for this procedure appears when the performance and speed of programs decreases, in the presence of broken files, slow copying and other difficulties.

You can carry out this process yourself using one of the popular methods. But, before starting the process, it is recommended to make a backup and recharge the battery by more than half.

The most popular formatting method is carried out using the algorithm:

Find the device in the menu and enter “Settings”.
“Memory” is selected.
Scrolls through information about the use of the device’s memory, and there is a “Memory card” section.
Enter the memory card subsection, statistical data scrolls.
Find “Remove card” and activate. When there is no such command on the device, this step is skipped.
Exit and re-enter settings. When this command is missing, the step is skipped.
Find “Clear card” and activate it.
Action is confirmed when necessary.

For method 2 of card formatting, the following algorithm must be followed:

The smartphone turns off.
The card is removed from the slot.
The card is connected to the laptop using a card reader, which is built into the PC.
Click "My Computer".
Right-click on the SD icon.
The “Format” option is selected.
The required file system is selected.
The checkbox next to “Fast” is checked.
The “Start” option is launched.

All you have to do is wait until the procedure is completed and the device card is fully formatted.

Resetting settings using digital codes

Another effective method to reset your device without using third-party software. For example, for gadgets based on Android OS there is a wide range of different combinations.

It is worth noting that each gadget manufacturer assigns its own reset codes. For this reason, before carrying out the procedure, it is necessary to clarify the combination for a specific model.

It's also important to remember that not all Android devices have this feature. Therefore, if your existing model is not equipped with this function, it is recommended to use another method. The procedure is done as follows:

Activate the “Phone” application;
In a new window, insert a combination of numbers;
Wait for the phone to reboot.

Restoring access to your account

If a user has lost the password to their Google account, it is recommended to use a special service called “Google Account Recovery”.

The step-by-step guide looks like this:

Go to the account login page.
Selecting the “I don’t remember my password” element.
Click “Difficult to answer.”
Selecting a recovery mode via SMS to a linked mobile device.
Enter the code from the message and click on “OK”.
Enter a new password and save changes.

Return to factory state using recovery

Today, every gadget based on the Android operating system has a special recovery mode enabled - recovery. It allows you to adjust some parameters and roll back the phone to the initial configuration. The device owner will only need to perform a few physical keystrokes. It is worth considering that the technique will differ depending on the brand and model of the device.

Many devices have a special button with a return home function. This is one of the controls that will be activated when the mode starts. The startup principle consists of briefly pressing some keys. A factory reset is performed using these instructions:

Turn off the gadget completely;
Use the volume and power buttons;
Wait for the recovery menu to appear;
A list will open in which you need to select “Wipe data/factory reset”.
Some manufacturers may say "Clear Flash" and "Clear eMMC";
Next, you need to tap on the line for deleting user files;
When finished, click on the system reboot button.

Important! To move to the recovery menu, you need to use one of the buttons to adjust the volume. You can confirm the selected command with the power button. There are also models in which recovery involves the use of a touch panel.

Unlock Tele2 mini for all operators

Tele2 Mini smartphones work in accordance with the specified settings only with the manufacturer’s SIM card. And to change the operator you need to unlock Tele2 Mini.

It is not necessary to carry out this operation illegally. There is a completely legal way. To do this, you need to come to the office and bring:

receipt for the purchase of a telephone;
packaging and documents for it;
the device itself.

The owner approaches the seller and officially asks to unlock the tele2 mini. An employee cannot refuse to provide this service to a person. He either carries out the necessary work himself or submits an unlock request to the service center. The unlock code should come in a message or email.

After receiving the code, a SIM card from another provider is inserted into the lot. When turned on, the sent numbers are entered in the window that appears. After this, any SIM starts working, not just Tele2.

Unofficial unlocking is best done if the user understands what needs to be done. The second slot is already configured to work with any SIM cards. But to activate the first connector, you need to do a little work:

Turn off the phone and remove the battery.
Insert a SIM card from another operator into the main slot.
Insert the battery and turn on the smartphone.
Enter 34127856 in the window that appears.
Reboot the gadget.

From this moment on, both slots are configured to receive a signal from the SIM, regardless of the provider.

Reset settings with a separate button

The modern mobile technology market is increasingly replenished with smartphones with a separate button for rolling back to the original state. It should be a small hole, inside of which the switch is directly located. To use the key, the user will need to use a thin object - a needle, paper clip, etc.

However, remember - by pressing the hardware switch, all user information from the device will be permanently erased. To avoid this, you need a backup copy of your data packets.

Smartphone models and their hardware keys

Users are often tormented by questions regarding how to perform a hard reset. Below is a list of smartphones that have their own methodology for carrying out the procedure. It is worth noting that even for one manufacturer the instructions will differ. It depends on the OS version, year of manufacture and design features of the model:

Samsung. Simultaneously hold down the Power, Home and Volume Up keys. On some models you will need to hold down the power button and volume down;

Where to download the firmware

It is better to download the software file from trusted sources so as not to introduce viruses. Typically the utilities needed are:

on specialized forums;
on the website ru.

Files for the Tele2 Mini 1.1 smartphone are common there, but there are also other versions. There are groups on social networks that unite smartphone owners, and in these communities they freely exchange firmware files, although not always official ones.

It is worth understanding that flashing a smartphone on your own does not always result in the desired result. The user acts at his own peril and risk: an unofficial update will invalidate the right to warranty service and repairs. The optimal solution is to ask again after the warranty period has expired.

Sequencing

Modification of a phone at home is carried out not only because it does not accept other SIM cards. The device may periodically freeze, reboot, and for ease of use it is better to reinstall the software. New versions offer features that the original software did not have.

Reset to factory settings using a computer

Visit your mobile device settings;
In the developers section, find the “USB Debugging” mode;
Next you need to check the box on USB tools;
Install software on your computer to interact with mobile devices;
Connect the smartphone to the PC using the original USB cable;
Activate command line;
Enter the following address “C:\Users\Username\AppData\Local\Android\Android-SDK\tools”;
In recovery, enter ADB reboot;
Wait for the system to reboot.

Attention! It is not recommended to disconnect the phone from the computer during the reset process. Otherwise, the firmware may be damaged.

To save information, you can use Titanium Backup, here is information about the possibility of data recovery after a hard reset Tele2 Midi (1.1).

How to reboot Android

There are several methods to restart Android smartphones:

Standard reboot. In this case, the owner of the device will only have to use standard tools. First, you need to hold down the power button for a few seconds, after which a window will open in front of the user with a choice of actions. Among them, you should select “Reboot”;
Forced reboot. This type of restart is needed in cases where the smartphone freezes or slows down. There may be several reasons for this behavior - overheating of the battery, clogged storage, etc.;
Emergency reboot. This method should be resorted to when the device stops responding to any actions. For this procedure, you need to remove the battery, let it cool and turn on the device after a while. You can also use the combination to launch the recovery menu.

How to reset Google account on Tele2 mini

When the user is not in a hurry, you can simply wait 72 hours and restore the account in the standard manner. But usually everyone uses more efficient methods.

Insert the memory card, click “OK” in the message that arrives. The memory settings window opens. Next, select “Application Data”, “All”, “Settings”, “Startup”, “Backup and Reset”. After the reboot, you no longer need to use the linked Google account.
Insert a SIM card, call somewhere, click add call, and turn off the call. Next, enter the number *#8#4636#*#*. In the settings that open, you need to press the back arrow, and then the user goes to the template settings. In “Restore and reset,” the link to the Google account is disabled and the credentials are cleared.

The illusion of data deletion

It is worth noting that rolling back to the initial configuration deletes personal data, but does not do so completely. In this case, the system erases only the addresses of the folders in which the files were located, and the content itself remains in Flash memory. It is for this reason that many specialized utilities allow you to recover deleted information after a reset. To avoid such circumstances, it is recommended that you familiarize yourself with the following procedures.

Data encryption

Smartphones have a special tool responsible for encrypting personal information. As a rule, it is located in the settings. To find it, you need to go to the “Security/Data Encryption” section. The essence of encryption is to install a special code, which can be a graphic key or a classic PIN. If you lock it in a timely manner, then even after recovery the files will be impossible to open without specifying the provided password.

Overwriting unnecessary data

A fairly effective method with which you can encrypt personal information. The bottom line is that the user will need to make several resets. After the first procedure, you need to fill the internal storage of the device with large unnecessary files. Then you will need to do a second hard reset, after which the necessary files in the Flash memory will be overwritten with unnecessary content. You can also use third-party software for this. For example, the Play Market has the “iShredder 6” application, which allows you to fill your gadget’s storage with information garbage. Additional functionality of the utility also includes the ability to delete specific folders, files, applications and caches before resetting.

Preparing to clean your device

Formatting may be needed in the following cases:

The user wants to give or sell his Android to someone. Typically, people do not want their personal information to be shared with third parties.
The owner of the device does not like that some applications take 10 minutes to launch or system errors occur that cannot be resolved. In such cases, formatting seems to be the best solution to problems.
The user has forgotten the screen unlock password. If other methods do not help solve the problem, you will have to perform formatting.

There are 2 main ways to format memory. If the device is operating relatively normally and the operating system is running on it, then performing the operation will be very simple. Otherwise, you will have to delete data through Android recovery mode, which will be a little more difficult. You need to keep in mind that before destroying data on a phone like the Samsung Galaxy S7 or S8, you must first back up the information.

Any of the available methods of cleaning the device erases all user files. This is why you need to back up your files before starting the process. To save information on a personal computer, it is recommended to use the Android Backup Restore program.

Then you need to follow these steps:

After installing the program, launch it and open the Data Backup & Restore panel. Then connect the device you want to format to your computer using a USB cable.
The user will be offered 2 options: Backup and Restore. You need to select Backup and mark on your phone the data you want to save.
Click the Backup button after the files have been selected. After some time, you will receive a notification that the data backup is complete. The program will clearly demonstrate that the files are in the right place.

What to do before resetting your data

First of all, the user must take care of the safety of personal data. Of course, you can connect the device to a PC and copy the necessary information to a stationary device. However, mobile OS has an integrated backup function. What is needed for this:

Open system settings;
Go to memory block;
Find the backup item;
Go to the “Google Drive” tab;
Move the slider next to the “Back up data” line. You can also manually transfer the necessary information to a computer or other device.

Copy important information from your device

The procedure used depends on which device the information will be copied to:

Computer. In this case, you will need a USB cable with which you can connect your smartphone. Next, you need to select important data and transfer it to the specified folder on your PC. However, this applies exclusively to media content. If we are talking about copying contacts and other similar data, you will need to install a special manager. AirDroid is considered one of the most popular;
Another smartphone. You can use Bluetooth to transfer files to another mobile device.

Formatting programs

There is no software in the Play Market that directly formats the device on command in auto mode. The list of software includes applications that include formatting as one of the tools for working with files on the phone.

The most common:

Root booster. Optimizes system performance, helps achieve proper results by reconfiguring OS components, deleting temporary files, empty folders, unnecessary applications, clearing the cache and supporting hibernation.
Application manager. The software helps organize and analyze applications for power; in addition, there is a chance to remove programs in groups at once.
Total Commander. A popular file manager that has great functionality. Completely deletes folder directories without using the recycle bin.

Remove your Google account from your device

Situations arise when the owner of a mobile device needs to disconnect from his Google account. For example, this may be related to the sale or exchange of smartphones. To complete the procedure, it is recommended to follow these instructions:

Open device settings;
Select the section with accounts and go to the “Users and Accounts” tab;
Find your profile;
Click on the delete key;
To confirm the procedure, you will need to provide a security code.

Method number 4.

Another way to reset a feature phone is as follows:

Turn on your mobile phone by pressing and holding the Power button;
Then open the settings menu;
There, select the “Reset” option;
Next, select “Master reset” and click on “Ok”;
Enter the security code. By default, this may be one of the following - 1122, 4321, 12345, 0000. Try each of the listed options in sequence;
Click on "Yes";
Complete the reset on your mobile phone.

Results

The most effective and safe way to reset is to use the device settings. It is only recommended to use it when the phone does not freeze and responds to commands. Otherwise, users resort to the recovery menu for help.

Based on expert opinion, a hard reset needs to be performed several times a year. This approach will allow you to get rid of excess debris that has accumulated during operation. In this case, it is recommended to make a backup copy of important information.

Method number 9

Well, the last way to reset your phone to factory settings is as follows:

Turn on your mobile phone by holding the Power button;
Dial *#7370#
Next, you will see the option “Restore factory settings”;
Click on “Continue”;
Enter the security password for your phone. The default is 1122, 4321, 12345, 0000, 12345, 1234, 3344, 5678, 4321, 0000, 9999;
Your feature phone will be reset to factory settings.

Features of the procedure

To find out how to set up the Internet on a Tele2 phone, you should familiarize yourself with the basic rules of this procedure:

If the parameters are not set automatically, the subscriber has the right to request the configuration to be saved or make changes in individual positions manually.
Sometimes it is recommended to first reset the default settings on your smartphone, and then register the positions that are correct for the provider’s network. This can be done easily through the main menu of the cellular device.
Settings can be ordered via a short SMS command (the service is free).
It is convenient to install changes in your personal account on the provider’s official portal if the user has an active profile.
You can request installation on any device of the Tele2 operator: mobile phone, modem, router. The parameters directly depend on the features of the operating system of the mobile device.

The configuration will only arrive if the SIM card is active.

Operation hard reset Tele2 Maxi will be simply necessary for you if:

Tele2 Maxi began to slow down and freeze;
If you have forgotten your Google account password on Tele2 Maxi;
Tele2 writes “Too many attempts to enter a pattern”;
If a Tele2 Maxi user has forgotten the pattern key;
If you need to return Tele2 to factory settings;
If you just want to clean your Tele2 Maxi smartphone.

When you hard reset Tele2 Maxi, the settings will be reset to factory settings, all user files and settings will be deleted. Therefore, before hard rebooting your Tele2 smartphone, save the data you need (photos, contacts, videos, music). All applications previously installed by the user will also be deleted. To save information, you can use Titanium Backup, here is information about the possibility of data recovery after a hard reset Maxi.

Rearranging the SIM card and entering the code

For Tele2 Mini, unlocking will be required if you decide to insert a SIM card from another operator into the phone. The whole problem lies in the NCK code, which is a kind of copyright protection - when installing a SIM card that is not similar to the brand of the device, a block occurs. After entering the code value, the connection will be unlinked from Tele2, and the phone will become operational for all global operators.

The Tele2 Mini smartphone has a very useful technical characteristic: two SIM card slots. You can try inserting the SIM card into another slot. In most cases, this helps, but it is considered a short-term solution to the problem because after a certain period of time the phone again requires an unlock code.

Main and front camera

The first thing I would like to note is the lack of automatic focus in the camera, although what else should you expect from 2 megapixels. The front camera is quite good; thanks to interpolation, 0.3 MP easily turns into 1-1.3 MP. The advantages of the Tele2 Mini main camera include:

Good white balance, some pictures have a somewhat unnatural tint, but the quality of the photo itself is high;
The most successful photographs and videos taken in daylight outside;
The average image file size is 700 kilobytes;
High quality display of photographed text.

The disadvantages of the camera include terrible shots taken under artificial lighting indoors; they turn out dim and unclear. To take a decent photo, you will have to turn on a bright light and take a long time to select the right angle. The flash is terrible, but selfies are tolerable, no worse than standard photos taken with the main camera. To improve quality, do not forget to connect pixels in the settings; instead of 0.3, use 1 or 1.3 megapixels.
