Reset settings on android to factory snow leopard. Reset settings to factory settings on Irbis TZ70. Restore settings with a special button

Sooner or later, many Android tablet users encounter a situation where the tablet needs to be cleaned and restored to factory condition. There can be many reasons for this, but basically it is either unstable operation of the device or “cleaning” of data before sale. There are also situations when the tablet stops turning on altogether or freezes when loading; in such cases, a full reset is not necessary.

First of all, it is worth separating two concepts: Hard Reset and Soft Reset.

• Hard Reset(Hard reset) - completely reset the device and restore it to factory condition. This procedure is similar to reinstalling the operating system. After a hard reset, you will lose all your data, including installed programs, contacts, and media files. However, do not confuse Hard Reset with flashing; if you have “custom” firmware installed or “Rooted”, then all this will be preserved even after a full reset.
  Before performing a hard reset, it is recommended to back up all necessary data. Simple media files can be easily copied to a memory card or computer using a file manager. To save backup copies of games and other applications, it is recommended to use special Back-Up utilities, of which there are a large number for Android today. But keep in mind that in case of an emergency full reset, none of the above will be saved.
• Soft Reset(Soft reset) - currently, a soft reset refers to a banal reboot of the device, which can be done either by pressing a special key combination on the tablet, or through the menu. Some tablets also have special reset buttons on the case. Before doing a full reset, it is definitely recommended to try a Soft Reset - perhaps a reboot will fix minor problems. On most modern tablets, rebooting is accomplished by long pressing the on/off button.

How to do a Hard Reset

Important! Despite the fact that Hard Reset does not delete data from MicroSD cards, it is still recommended to remove the memory card from the device before performing this procedure.

• Method No. 1. If the tablet is working, go to Settings, select “Backup and reset”, and click “Reset phone settings”. Please note that depending on the firmware version, the name and location of menu items may vary.

To boot into Rovery mode, turn off the tablet, then hold down the volume up button (or down, depending on the model) and simultaneously press the power button or the “Home” button (depending on the tablet model). Keep both buttons pressed until the Android logo appears. After loading recovery mode, in the menu that appears, select the “wipe data/factory reset” section. For your information, in Recovery mode the touch screen does not work, and all menu navigation is done with the volume rocker, and the selection button is the power button or the “Home” button (again, depending on the tablet model). For more detailed instructions, see the article ““.

Hard Reset, also known as Hard Reset, is done in two main ways. Regardless of the method you choose, take care to back up your personal information, and also remove the memory card from your tablet and, just in case, a SIM card, if you have one.

1. Using the menu (if the tablet turns on)

If the tablet is fully operational, the pattern key is not locked, and you have the opportunity to get into the settings, be sure to use this method to do a Hard Reset (hard reset) and reset the user settings to factory settings.

1. All you need to do is go to the settings and find the item Recovery and reset.

2. Then you need to select the item Reset.

4. As a result, Android will issue a final warning that you want to destroy everything and will not be able to restore anything. If you haven't changed your mind, choose a team Erase everything.

5. The tablet will reboot, and to show you the full depth of the process, you will see a screensaver of atoms and molecules spinning in the belly of the Android robot.

6. This is normal, after a couple of minutes the screensaver will disappear, the tablet will start with factory settings and applications, as if you had just brought it from the store.

2. Through the Recovery menu (if the tablet does not turn on)

If a software failure occurs in the tablet, it stops starting, there is an “eternal loading”, or the device is locked with a pattern key - you have only one way out - get into Recovery mode, i.e. recovery mode. The Recovery menu can only be accessed when the tablet is turned off. To do this, use a special combination of simultaneously or sequentially pressed physical buttons on the tablet, which are located on the device body. Typically this is the volume rocker +/-, the power button, and/or the Home key. The general procedure is as follows:

1. Turn off the tablet. The battery must be fully charged. If you are not sure that the battery is fully charged, or the battery is weak, it is better to carry out all manipulations by connecting the tablet to the network

2. Press and hold the key combination (examples of such combinations for your device model will be below), and wait until the Recovery mode opens

3. Navigate through the menu using the volume rocker (touch control is possible in some tablets). Choosing a team wipe data/factory reset(translation: erase base/reset settings to factory settings). To do this, you need to press with your finger if the control is touch-sensitive, or with the power key, which in this case serves as a button OK.

5. After this, you must give the reboot command. To do this, select the item reboot system now(translation: reboot the system now)

6. The tablet will think for a while, all data and settings will be erased, and it will turn on itself.

It is worth noting that each tablet manufacturer sets its own set of keys to access the Recovery menu, so only general methods that are relevant for different brands of devices have been collected.

3. If you still can’t get into recovery mode, the most clumsy option is to reflash the tablet.

Please note that this article is not exhaustive information on all tablet models. Therefore, if you do not find the manufacturer of your tablet in the list, try all the keyboard shortcuts described above, perhaps some method will be suitable for your device. If you still haven’t managed to get into Recovery mode, write the model of your tablet in the comments, and we’ll try to help if possible.

Tablets running Android OS have many advantages, the main one being the relative cheapness of the device. But for all inexpensive devices on Android, there comes a time when your fast and productive gadget begins to slow down terribly, lag and freeze (freeze is a delay in drawing frames in a game or system). Replacing the tablet with a new one does not seem like the best solution, because not so long ago it worked as it should. Then you can return the gadget to factory settings or reset the settings - this will certainly help breathe life into your device. In this article, we will show you how to do a Hard Reset on an Android tablet using detailed instructions and various methods.

Why roll back settings?

The main reason why users delete all their settings and applications from the device is its insufficient operating speed. Overloaded with various programs, games, sometimes even viruses picked up on the Internet with a pirated game or program, the gadget can no longer cope with everyday tasks and begins to infuriate with its slowness! In such a situation, Hard Reset will really help restore the gadget to its former performance.

Incorrectly installed custom (unofficial) firmware can also be a reason to completely wipe your Android tablet. However, in this case, a hard reset will not be enough: you will also need to install the official service firmware to get the tablet in order. But it's a little more complicated

Errors caused by obtaining root rights (this is the name for access to the root file system of the device, which allows you to change a large number of settings) or incorrect use of applications that require these same root rights. It is worth noting that after a hard reset, your root rights will be lost and, if necessary, you will need to obtain them again.

Reset via settings menu

Let's start with the simplest method - resetting the settings in the settings menu. This method is suitable for those who want to remove absolutely all installed applications, all files, all accounts and everything from their tablet. If you didn’t install unofficial firmware (if you don’t know what it is, then you definitely didn’t install it), then you will receive the tablet in the same condition as when you purchased it. Therefore, before cleaning your gadget, download all the necessary files to your computer or to the cloud. It is also worth noting that for this operation the device must be at least half charged.

Let's look at this operation step by step:

1. To get started, go to settings, click on “Backup and reset”.
2. Here we are interested in “Reset settings”. You will be reminded that if you perform a factory reset, you will lose all data stored on this tablet.
3. If you are sure that you are ready to reset, press the “Reset settings” button (or something similar, for some reason the inscription changes from tablet to tablet).
4. A robot will appear in which gears or some geometric shapes are spinning, reminiscent of the atomic structure of some substances.
5. After 5-10 minutes the tablet will boot itself.

Attention! Before performing this operation, be sure to copy all important data from the device, otherwise it will be quite difficult to restore it.

Reset via service code

If for some reason the settings menu does not appear, you can do a Hard Reset by entering a special service code in the “Phone” application where you usually dial the phone number of the called party (if you have such an application on your tablet) . Here's the code itself: *2767*3855# . Be careful because... no warning will pop up before recovery. Further processes occurring with the tablet are similar to those described in the first method.

In recovery mode, you can apply various updates or restore the device’s functionality at the software level. This method can be used if the tablet does not turn on. Make sure your gadget is charged. If it was turned on, turn it off. To get into recovery mode, follow the instructions for your model:

• SAMSUNG: On a Samsung tablet, hold the Volume Up, Power and Home buttons until they vibrate slightly;
• LENOVO: on a Lenovo tablet, you need to simultaneously hold down both volume buttons and hold them down for a few seconds, then release them and press the volume down key once;
• SONY: Hold the Volume Up and Power buttons until the screen turns on. After that, stop holding the Power button and start holding both Volume keys;
• HUAWEI: hold the Volume Down and Power keys for about ten seconds;
• PRESTIGIO: on the Prestigio tablet, in order to start the recovery, you need to hold the volume up and power keys.

After entering the menu in any of the presented manufacturers, using the volume buttons or the screen touch, select Wipe – Wipe data/Factory reset t (selection is made either by pressing the screen, or the power button, or the home button). The tablet will do everything itself and reboot.

Reset using a computer

If your tablet does not have volume buttons, you can reset it through your computer. This is done by programs produced by the manufacturer of your tablet. There is no point in describing the recovery process in this way, because... Each program must have its own instructions. You can find the required program and manual for it on the Internet on the manufacturer’s website. All you need is a USB cable from the gadget box to connect it to your PC, drivers downloaded in advance, and some free space on the hard drive of your computer or laptop.

Articles and Lifehacks

The need for this procedure may arise for a variety of reasons. For example, the user may be interested in how to restore settings on the tablet if the device does not turn on, freezes, or the password (pattern pattern) has been forgotten.

Carrying out such a task is not very easy: it will require attentiveness and accuracy. This article will tell you how to do this.

How to reset and restore settings

If our device freezes, just hold down the power button for ten seconds, after which it will be turned off. Turn on the tablet again.

These steps will help us perform a simple reboot. Unfortunately, it is not always effective. Sometimes a harder reboot, also known as a Hard Reset, is required. It will help you reset your device to factory settings.

In what cases might a Hard Reset be required? Most often, users resort to it if the device does not turn on, is extremely unstable, or simply needs to be sold second-hand, after having been “cleaned” first.

After a hard reboot and rolling back the settings to the factory state, all personal data and installed applications will be lost from the tablet.

To restore personal information in the future, you need to synchronize with your Google account. In addition, it is recommended to first transfer all important data to a memory card.

If the device does not work correctly, freezes, does not turn on, and so on, Hard Reset will be the only way out of the situation, since a regular reboot is not enough.

1. We turn off the tablet (if it is not already turned off) and go to recovery mode, that is, into recovery mode.
2. To do this, we hold down a certain key combination, and the specific combination depends on the brand and model of the device.
3. For example, these could be volume up/down keys and a power button, or the above buttons together with the “Home” button. Newer mobile devices have a touch recovery menu.
4. After entering recovery mode, go to “wipe data/factory reset” (the item may be called a little differently) and select “Yes - delete all user data” > “reboot system now”.
5. The reset process should take no more than 60 seconds. After this, the device should reboot.

A lot has been written about how to restore settings on a tablet. In addition, there is a fairly wide range of special software that is specially designed for resetting and then restoring settings.

One such program is Android Recovery. It's completely free.

Other reset and recovery methods

• If the tablet turns on and works more or less correctly, perform a backup, and then go to the “Restore and reset” item through the settings.
• There, select “Reset” > “Reset Tablet PC”.
• A reboot is being performed, upon completion of which a rollback to the factory state will be performed.
• This is how the most common reset is done. This deletes all information from the tablet’s memory, including Google account data, photos, music recordings, all downloaded applications, their settings, and so on.
• As already mentioned, synchronization will help restore all important information.

The next method is even simpler than all those described above. We dial a special service code. The specific combination will depend on the manufacturer and brand of the device.

For example, it could be *2767*3855# or *#*#7780#*#*. In general, such a reset will take no more than a few minutes.
