This mode is nothing more than factory settings and can be used at any time to test the gadget. Using Factory Mode on Android, you can test anything, sound, keys, backlight brightness. You can also clear the cache, roll back the device’s operating system to factory settings, calibrate the device, clean the flash drive, and much more.

Factory Mode menu on English language, so when experimenting with its capabilities, be careful, otherwise there is a chance of losing all the data on your Android gadget.

Smartphone manufacturers, despite the fact that the same OS is installed, the menu may be slightly different. But for the most part, Factory Mode contains standard set points:

• Essential Test is the main test of the device;
• Full Test - a complete test in which absolutely all parameters of the smartphone are checked;
• Item Test - selective, you can test individual functions yourself;
• Signaling Test - checking the SIM card;
• GPS - positioning check;

When a test of any smartphone system is completed, one of two inscriptions Test Pass or Test Fail appears. In the first case, the testing was carried out successfully, and in the second case it failed.

When does Factory Mode appear?

This Factory Mode menu appears on Android in two cases:

1. When forced by pressing a key combination.
2. And when the OS refuses to boot.

Usually the second case is typical for the devices of those craftsmen who independently try to reflash the device, without having the proper experience and skills for this, or to obtain Root rights. A similar mode is Fastboot Mode.

On smartphones various manufacturers Factory Mode menu brings up different ways. Basically this is the upper or lower position of the volume swing while simultaneously pressing the power key. Sometimes there are combinations of three keys: volume, power and home.

After completing this simple manipulation, open the settings menu. I was able to enter Factory Mode by simultaneously pressing the volume up key and the power button. On new smartphone models, you can navigate through the menu using touch screen, but most commonly used for navigation is the volume rocker. To enter the selected directory, simply press the power key.

How to leave Factory Mode

When this Factory Mode menu is launched normally, exiting it will not cause any difficulties.

Therefore, before starting any intervention in software make a backup copy of this section so as not to think about what to do with Factory Mode. This will help save your nerves and save time on resuscitating your Android devices. But even this will not save you from going to the service center, since only there is the necessary equipment.

Friends! Today there is so much talk about the OS, recovery, all sorts of words with the root -boot-, that if you don’t know something, you feel stupid (I’m not humiliating anyone, no). That's why I decided to tell you about this.
Attention! No one is responsible for all your actions except you!
And it’s not for nothing that this topic has such a name, because I’ll talk about Recovery and Factory mode. I think many have heard about recocery, but what is it? This is a set of programs for operating with the OS, such as backup and data recovery, and so on. But few people have heard of factory mode. This is a mode that allows you to check the phone's functionality. You can check everything at once or separately. But more on that later. Important: before operating in recovery and factory mode, charge the device to at least 50%, since all actions in these modes consume a lot of battery.
1. How to go: If you have volume rockers, then turn off the device. If you don’t have them, then hold down the “home” button. Then, holding them and the power button, wait for this window (it may not appear, it’s okay):
2.Mode selection: Now we choose what we need. For recovery - sound+, for factory mode - sound-, respectively.
3. Let’s understand what, why and how:
This is what recovery looks like:


Let's figure out what's what:
reboot system now = system reboot;
apply update from sdcard = unpacking archives and installing firmware and other contents of archives (in most cases, root rights are required);
wipe data/factory reset = full reset settings;
wipe cache partition = clear cache;
backup user data = backup of all data. Need ~200 MB on memory card);
restore user data = restore data from the backup made in the previous step.
Now factory mode (not available everywhere):

1.Tpupgrade = improvement touchpad at the bottom of the device;
2.Full Test = full phone test;
3.Item Test = selection test;
4.Test Report = test notification;
5.Signaling Test = SIM card signal test;
6.GPS Test = everything is clear here, GPS test;
7.Reboot = reboot.
4.Precautions: Follow the written rules and you will reduce the risk that something will happen to your phone.
1. Charge the device to at least 50% if you want to make a backup or reflash, etc. ;
2. Let the device cool down: while performing the above steps, the device becomes very hot. If it gets too hot, you better remove the battery.
In principle, that's all. Good luck with flashing, etc.!

On any device running operating system Android, there is a special . Service specialists use it to test the operation of the smartphone and debug the installed software. Regular user resorts to the services of Recovery only in one case: when it is necessary to restore the phone to factory condition.

Such the operation is called Hard Reset and is used in the following situations:

• restore the functionality of the device damaged by the installation new firmware or applications, otherwise impossible;
• Pre-sale preparation of the device is carried out.

note

A hard reboot completely deletes all traces of user presence: contact database, message archive, all saved files and installed applications. Therefore, before resetting the settings, you must perform useful information through cloud service or just to an SD card.

Methods for activating Recovery mode

Before performing the Hard Reset procedure, you must also disconnect the battery for 30 seconds. After this, the Recovery mode is launched by pressing several keys simultaneously.

Different versions of the Android operating system installed on devices different manufacturers, provide for the use certain combinations buttons on the smartphone body. The most common options are the following combinations:

If the mode was activated correctly, the message “ Android Recovery"(or "Factory mode") and the corresponding menu below it. If pressing one of the key combinations did not lead to the desired result, turn off the phone and repeat the procedure again using the next key combination.

Problems of Chinese smartphones

Will be useful

On devices made in China, the Recovery menu is often displayed on Chinese. This creates additional difficulties for users, which, however, are completely surmountable.

First of all, we must determine whether the Recovery mode or some debugging information is simply displayed on the screen. To do this, look carefully at the beginning of the first line. The first two hieroglyphic characters are very similar to the combination capital letters: Latin “I” with elongated horizontal upper and lower elements and Russian “G”. Therefore, if the text on the screen begins with “ІГ”, we are most likely in the right place.

The second evidence that this is the Recovery menu, albeit in Chinese, is the presence of Latin characters “MMC” in the seventh line. These three letters complete the text of the line.

Mobile gadgets have a large number hidden possibilities, one of which seems to be the so-called factor mod.
