Is there a BIOS (Recovery-Mode) on Android and how to enter it. Bios Settings - Detailed instructions in pictures

Open the computer lid and carefully inspect all its insides. Find the motherboard. You need to carefully examine it and find the coin cell battery. Take it out and set it aside for a few hours (5-6 is usually enough).

Due to the loss of constant power, the data in the BIOS will return to its original values. The access password will also be reset. The next time you turn on your computer, simply enter the new settings.

Method No. 2

Some modern computers make the user's task much easier. They have special connectors next to the battery that allow you to clean the BIOS memory without resorting to such drastic measures. You can see the exact location of these connectors in the instructions.

If you have lost the instructions, go to the manufacturer's website. All the necessary information should be located there. When the computer is turned off, close these connectors. The data will be reset and you can enter new parameters.

How to log in to Recovery? Many instructions for upgrading and flashing Android require you to perform actions from the Recovery menu. What kind of mode this is and why it is needed you will learn from this article. What is Recovery? Recovery is a special Android boot mode in which:

  • Perform a full Android data reset
  • flashing a smartphone
  • get Root rights

How to log in to Recovery? The Recovery menu, as a rule, is found in all Samsung smartphones and tablets, but not available in other brands of Android smartphones, but it can be easily added by flashing this section to your Android device.

If an Android smartphone has a Recovery menu and it has not been changed, then it is called STOCK, but if it did not have one or third-party Recovery menus were installed, it will be called CUSTOM.

Custom Recovery comes in mainly two types CWM And TWRP, less common 4ext,Philz C.W.M., (different development teams).

Mobile tandem of the week

On October 18, Google and Samsung presented the world with a new mobile alliance: the Android 4.0 Ice Cream Sandwich operating system and the first Samsung Galaxy Nexus smartphone running on it.

The main feature of Ice Cream Sandwich is its versatility: the same system for both smartphones and tablets. Although, of course, the user interface itself and some other innovations are interesting, which we are hot on the heels of.

Now, another question is more pressing for observers - when other Google phones will receive an update to version 4.0. There is information on this matter. With the first “Nexus” (Nexus One), alas, there are still “misunderstandings”. But the previous Samsung Galaxy Nexus will receive an update a few weeks after the newly announced Nexus goes on sale (on store shelves in November 2011). But the Motorola RAZR, another new smartphone, will receive 4.0 only at the beginning of 2012. There is no information yet about updates to 4.0 for other Google phones, say, LG Optimus 3D. This smartphone is at the disposal of the editors, so if one appears, we promise to tell you about our impressions.

But still, no matter how good the new “Google” operating system is, without the appropriate frame (Samsung Galaxy Nexsus), the presentation would hardly be able to attract so much attention from the audience. Even visually in photographs, the smartphone looks large, which is not surprising: the diagonal of the HD Super AMOLED screen with a resolution of 1280x720 pixels is 4.65 inches.

Inside, many probably expected to see a more advanced processor than the 1.2 GHz dual-core one. Otherwise, the Nexus most likely meets expectations and is not inferior to many other new smartphones: 1 GB of RAM, 16 or 32 GB of internal memory, a 5-megapixel camera with autofocus, LED flash and the ability to record video in Full HD (1080p), the communications set includes: 3G HSPA+ or LTE, A-GPS, NFC, Wi-Fi 802.11a/b/g/n and Bluetooth 3.0, microUSB port and 1750 mAh battery. The dimensions of the Galaxy Nexus are 135.5 x 68 x 8.94 mm, and the weight is 135 g. As we have already said, the Google Phone will go on sale in November. The cost of the device will be about $700.

Revival of the week

Last week, Motorola introduced its new Google phone Motorola Droid RAZR, which, apparently, should help the company “revive” the once very popular RAZR brand. But this time it's not an elegant clamshell, but a thin (7.1 mm) candy bar, the back of which is covered with Kevlar. Besides, this is not a phone, but a smartphone. Perhaps the device will appeal to potential buyers: the new product does not at all look like a “remnant” and the design really resembles the legendary RAZR.

The current version of the OS (Android 2.3.5) can be updated to version 4.0 next year. The Droid RAZR has a 4.3-inch Super AMOLED screen with a resolution of 960 x 540 pixels, a dual-core processor with a frequency of 1.2 GHz, 1 GB of RAM and 16 GB of internal memory, an 8-megapixel camera with Full HD video recording function and a battery at 1780 mAh. Dimensions - 130.7 x 68.9 x 7.1 mm, weight - 127g. Sales of the smartphone will start in the States in November. With a contract, the Googlephone will cost $300, without - about $700.

Trinity of Windows smartphones

Along with bright smartphones from Samsung and Motorola, supposedly official photos of a WP7 smartphone from Nokia appeared on the Internet last week. This was hardly an accidental leak: it wouldn’t hurt the company to be in such company and stir up interest in its own event, which will take place this week.

So, externally, Nokia 800 (previously mentioned under the name Sea Ray) is the spitting image of the Nokia N9 MeeGo smartphone. Colors: blue, black and pink. Estimated performance characteristics: 3.7-inch AMOLED display, 1.4 GHz processor, 8-megapixel camera with autofocus and 1540 mAh battery.

Meanwhile, Samsung demonstrated two new Windows Phone products at the AsiaD conference, which took place from October 19 to 21. Both (Samsung Focus S and Focus Flash) are made in a candy bar form factor and run Windows Phone 7.5 (Mango) and a 1.4-GHz Qualcomm processor. On sale - in the fourth quarter of 2011.

Samsung Focus S has a 4.3-inch Super AMOLED Plus screen with a resolution of 800 x 480 pixels, 1 GB of RAM, an 8-megapixel camera, a GPS receiver, communications: Wi-Fi 802.11 b/g/n, Bluetooth 3.0 and HSDPA.

The diagonal of the Samsung Focus Flash Super AMOLED screen is smaller: 3.7 inches, the main camera is less advanced (5 MP), the Wi-Fi module is the same (802.11 b/g/n), but Bluetooth is only 2.1.

Hybrid Devices of the Week

At the AsiaD conference, in addition to Windows smartphones from Samsung, they also showed more interesting devices. One of them is ASUS PadFone, a smartphone (4.3" diagonal) in tandem with a docking station in the form of a tablet (10"", resolution 1280 x 800 pixels). Remember when it was first demonstrated on? So what's new? There is not long to wait for the release - this is the first quarter of 2012, plus, as planned, the device will run Android Cream Sandwich.

The second gadget, which was also demonstrated at AsiaD, is the second version of the ASUS Eee Pad Transformer tablet. Again, the axis is Android version 4.0 and a quad-core (!) processor, plus the ability to work without recharging for up to 14.5 hours! The Transformer Prime tablet is quite thin - 8.2 mm, and the diagonal size is 10 inches. We are waiting for November 9 - the official announcement will take place on this day!

Antivirus Software of the Week

Most often, gadget lovers do not read the news about this or that antivirus software: what could be fundamentally new and interesting, at least for a non-professional? This is partly true. That is why today we decided to pay attention to the announcement, which cannot be called a pass-through. This is truly a fundamentally different approach, and anti-virus software from other manufacturers will soon “go” in this direction. But will it make it easier for specialists to work and will end users be more confident in protection? We think any of our readers will be able to answer these questions by reading more about the new initiative called McAfee DeepSAFE.

First of all, it is worth recalling that McAfee, known for its security solutions, was recently acquired by Intel. The initiative is understandable; all that remains is to wait for the concrete results of this acquisition. So what is McAfee DeepSAFE technology, which includes the personal and enterprise products McAfee Deep Defender and McAfee ePO Deep Command?

In short and succinctly, McAfee DeepSAFE is the world's first module for antivirus software that works regardless of the OS!

Perhaps this is bad news for the paranoid: after all, as you know, what one person can create, another can break. However, you should not think about the machinations of interested individuals and companies who would probably benefit from being able to gain access to any computer in this way at any time: after all, innovations and changes in the field of security solutions do not arise out of nowhere, and they are dictated most often external threats. It is also worth mentioning that the new software from McAfee has quite strict hardware requirements. For example, the processor in the author’s machine does not answer them: it must be Intel Core i3, i5 or i7.

As an example, it is worth recalling that just a month or two ago the world’s first BIOS virus was recorded, which does not “kill the BIOS, but “lives” there. Its name is Trojan.Mebromi (or Trojan.Bioskit.1), it is capable of modifying the BIOS (at the same time changing the contents of the boot sector of the hard drive). Important! None of the currently existing antiviruses is capable of “overcoming” a virus registered in the BIOS. So McAfee DeepSAFE is a good answer to such malware and an excellent help for IT specialists. And for Intel (bearing in mind that the vast majority of home and corporate desktops/laptops run on their processors) this is a very important initiative, because support is performed at the hardware level and goes beyond the OS.

UEFI - successor to BIOS

It is unlikely that most people associate the abbreviation UEFI with anything other than the football UEFA. However, this abbreviation, little or not at all familiar to most people today, in the foreseeable future risks causing emotions no less strong than the defeat of our football team. Yes, yes, this is not a joke: for example, motherboards with UEFI chips are already being announced... But first things first.

BIOS (Basic Input/Output System) has successfully provided the operating system with access to the computer hardware for three decades... It is being replaced by UEFI (Unified Extensible Firmware Interface), which is more similar in its capabilities with the operating system. That is, with its help it is possible to access not only PC hardware, but also, for example, surf the Internet. Now remember the contents of the previous chapter. It turns out that UEFI is a great environment in which both viruses and antiviruses have room to frolic;)

The basic input/output system (BIOS), which almost every Windows user has encountered, is missing on Android. Instead, all mobile devices with this operating system use the Recovery engineering menu, which many people still call BIOS out of habit. Therefore, let’s look at how to enter the BIOS on Android.

Ways to enter Recovery Mode

Entering Recovery mode is done differently for different models of smartphones and tablets. This can put the average user in a difficult situation.

There are several ways to get into the recovery environment of a mobile device running Android OS:

  • From the gadget menu;
  • Using a specific combination of mechanical keys;
  • Through additional software installed directly on the phone;
  • Using a PC and special software.

Login to BIOS through the device menu

For all mobile devices, when you hold down the Power button, a window appears with possible options for action. The standard set of functions is shutdown and reboot.

However, some gadgets additionally have the line “Reboot to Recovery”. If your smartphone or tablet has this option, then you are in luck, as you can enter the BIOS in just two clicks.

In the Recovery environment, there is no standard graphical interface, and all operations are performed using mechanical volume and Power buttons. It should also be noted that all actions performed are irreversible and may result in failure of the device and loss of user data.

You can also enter BIOS on Android using a certain combination of buttons. However, this set may differ from one manufacturer to another. Let's look at the procedure for enabling BIOS mode for popular brands of mobile phones and tablets. All operations are performed with the power turned off and the USB cable and charger disconnected.

Enabling BIOS on Android Using the Quick Boot App

To quickly enter the Recovery environment, special software has been developed that can be downloaded to your phone or tablet completely free of charge via Google Play. One such program is Quick Boot. To enter the BIOS using it, you must:

After the automatic reboot, you will be able to freely work with the engineering menu. To exit this area, you will need to select the “Reboot system” option.

Many situations may lead to the need to reset the Android system, for example: frequent device freezes, the Android system cannot boot, or the gadget unlock password is lost. "Hard Reset" is a radical solution that allows you to return the device to working condition.

Looking ahead, I note that “Hard Reset” deletes data only from the device’s memory, without affecting the SD memory card, although there is option 2, which allows you to affect it as well.

Attention!!! All contacts, installed applications, messages, etc. will be deleted. It is highly recommended to back up your phone data before starting the reset operation! One backup method is .

Option 1. Recovery Mode

Turn off the device and boot into Recovery Mode by pressing several keys together. Each manufacturer has its own buttons:

  • "+" on the volume rocker and the "ON/OFF" button;
  • "-" on the volume rocker and the "ON/OFF" button;
  • Volume "+" and "-" together and the "ON/OFF" button;
  • Volume "+" and "-" together, the "Home" key and the "ON/OFF" button;
  • In Chinese devices, hold down the volume key and connect the charger.

The volume up/down buttons allow you to move up and down through the recovery menu, and the ON/OFF button selects a command. In the latest devices, control in "Recovery Mode" can be normal (touch).

Select "wipe data/factory reset", and confirm the system reset by selecting "Yes - delete all user data". When the wipe is complete, select the "reboot system now" option.

It will be a little more difficult to see the reset on Chinese phones. For example, in the "iconBIT NetTAB Mercury XL" or the clone "Samsung Galaxy S4 GT-I9500" the recovery menu is in Chinese. If you have the same situation, the picture below shows the Russian translation of the "Recovery Mode" menu.

To navigate through the menu, use only the volume "-" key, because... The "+" key is used to return to a higher level. To select the highlighted command, press the ON/OFF button.

To run a full reset of Android settings in Chinese phones, you need to select the 6th option. What's funny is that after selection, the command will be executed without confirmation.

After a few minutes of waiting, your Android device will boot up as it did when you first started it after purchase, possibly asking you to add a Google account.

Option 2: Restore and reset

In Android settings you can see such an item as “Backup and reset”. It is designed to reset system settings and restore from a backup saved on the Internet.

Click on the "Reset settings" option.

Scroll down and optionally check the box next to "Clear phone memory - card" to delete personal data from the SD memory card, such as photos, music and other user data. Click on the "Reset phone settings" button.

User data will be deleted and factory data will be restored.
