Omega firmware for samsung galaxy s3. MIUI V5 review - the best firmware for Galaxy S3

Facebook

Good day. Today I want to talk about my experience using Cyanogenmod 10.1 on my SGS3.

First of all, how did I come to Cyanogenmod?

The first time I became acquainted with the firmware of this team was in 2011, back with version CyanogenMod 7.1 on Samsung Galaxy Ace. After that, I tried a lot of firmware, both on SGA and SGS3, but decided on Cyanogenmod.

When the firmware came out of Beta status, I installed it, fearing only that the problem with excessive power consumption had not been fixed, but my fears were not justified. After a month of using the firmware, I can say that the phone lasts 20-24 hours with fairly active use, and 40-48 hours with average load.

Performance:

One of the reasons for switching from the stock SGS3 firmware was the brakes and rather slow robot. But with Cyanogenmod 10.1, I didn’t notice any problems with brakes, crashes, or reboots after a month, and I can say that the smoothness of the robot is about the same as in the LG Nexus 4.

I also forgot to say that after updating from 4.0.3 to 4.1.2 the phone constantly lost the network and at the very inopportune moment The network disappeared, this was cured by rebooting. I have read a lot of information about this problem. but I still haven’t found a solution. Since switching to Cyanogenmod 10.1, I have no longer encountered this problem during my entire use.

If we talk about indicators in benchmarks, then AnTuTu Benchmark showed 18598 parrots, which is pretty good for a flagship of early 2012.

Dialer:

One of my requirements for a smartphone is a good and fast dialer. In stock firmware phone book one of the best I've seen on android, but it's VERY VERY VERY slow. The standard Android dialer does not have this problem. This is yet another proof that all the add-ons to Android make it not only more beautiful and functional, but also slower and more buggy.

Multimedia:

So, what's the deal with music and video in Cyanogenmod 10.1?

Let me answer briefly: quite bad compared to the stock Samsung firmware. But there is always a way out: the standard Cyanogenmod audio player is Apollo, but there is no video player as such: it is combined with the Gallery. After spending 10 minutes in Google Play I found a way out. My new audio player is stock Android player “Play Music”, and the video player is DicePlayer.

If you compare the sound quality in original headphones, I can note that the quality has become a little worse, but the maximum volume has increased.

Camera:

One of the factors that prevented me from switching to Cyanogenmod 10.1 firmware was the camera. In Beta versions of the firmware, the camera gave off a blue or green tint, and the pictures were quite Bad quality. But in the final version this bug was fixed.

The camera app itself is pretty good, and most importantly, it's fast and allows me to take a photo exactly when I want it. But in terms of the range of settings it is slightly inferior to the camera from Samsung.

Sample photo(I just cropped the photo) :

Conclusion:

Cyanogenmod is one of the best custom firmware. For my Galaxy this is a second wind. I am very pleased with my choice and can recommend Cyanogenmod 10.1 RC2 to all SGS3 owners.

P.S: Don't judge strictly, this is my first article. If you have any comments or suggestions, write in the comments.

If your smartphone is already several years old, and you are already tired of it, is it possible to breathe into it? new life? Make him please you again for some more time? Most users will most likely say that no, the smartphone is outdated, there is not enough RAM, the processor is no longer “cake”, there is not enough built-in memory, and the screen resolution has begun to hurt the eyes. I won’t even say anything about the lost battery capacity. But if you have a popular flagship from previous years, then you can still do something.

Battery replacement

In most cases, the battery starts to fail first. A year, a maximum of a year and a half, and we notice that our smartphone hardly “survives” not only until the evening, but even better until lunch. If the battery is removable, then the problem is minimized.For some smartphone models it is not difficult to find an original battery. True, the price will not be entirely humane. A good alternative would be Craftmann batteries. Finding such a battery will not be a problem.

Again, there are many alternative options, let's consider one of them. This is a monstrous battery, with a stated capacity of 6400 mAh. Comes with back cover for a smartphone, instead of the original one. When installing all this, the smartphone is completely disfigured, but you get a guaranteed two days of work.

Of course you can take it with you everywhere portable accumulator, or at work constantly keep your smartphone on charge, but you must admit, each of us wants more autonomy from our smartphone, therefore, replacing the battery cannot be avoided, in any case.

Bored or lagging firmware

Now we come to the most interesting part. Most users of early Samsung flagships sooner or later encountered the problem of “brakes” on their smartphone. Desktops were scrolled through with noticeable slowdowns, the dialer opened for several seconds, the camera took a long time to start up... All this began to irritate, and some users decided to reflash their smartphone to custom firmware. In our case, there are very, very many different options. Perhaps the most stable and supported firmware is Cyanogen Mod. Samsung stopped updating its 2012 flagship SGS3 for a very long time. The latest official version of Android there seems to be 4.2.2. or 4.3.1. But the Cyanogen Mod firmware is already available on Android 6.0.1. Of course, there will most likely not be an Android 7 for this smartphone, but still thanks to the developers for that. But as of this year, to the great regret of fans of this firmware, the Cyanogen Mod project has been closed... Perhaps enthusiasts will release their modifications for some time, but officially, we will no longer receive Cyanogen Mod. But there is also good news, instead of Cyanogen Mod, we got LineageOS, and thanks to it, our SGS3 still received Android 7.1.1!!!

A brief overview of LineageOS for the 3rd Galaxy.

Firstly, I want to say that interaction with the smartphone interface does not leave a depressing impression, as on stock firmware. But still, you shouldn’t expect much either, the hardware is old. The smartphone works quite quickly, but turns on with some delay. The dialer opens faster than on stock, desktops turn over smoothly. Applications open in different ways, some quickly, and some take 2-3 seconds to complete. But we have Android 7.1.1! True, the assembly is “nightly”, that is, some functions of the smartphone and programs may not work correctly. There were already stable builds on the Cyanogen Mod firmware, and in general, the operation of the smartphone was satisfactory. But enough about Cyanogen Mod, let's explore the features of the LineageOS firmware. In the smartphone settings, in the “About phone” section, we can see information about the phone’s status, device model, Android version and firmware:
And this is what it looks like main screen:
A few words about applications from Google, after installing LineageOS, they simply do not exist, and we will have to install them ourselves. It's as simple as installing the firmware itself. When you have flashed LineageOS, without leaving recovery, install GApps (a package of programs and services from Google). You can download them. And after installing all this, we will see the following picture: all Google applications will appear on your smartphone!

Unlike, for example, MIUI, our firmware has an application menu:
The notification shade, as on all smartphones, is called up by swiping from the top of the screen down; if you make a short swipe, notifications will open; if you swipe long, then icons for various switches will open:

In general, the LineageOS firmware is close to “naked” Android, only there will be more settings. For example, you can change the color of the indicator for different events. In stock, there are only three colors, but on LineageOS you can mix these colors the way you want.

What else can you tell about this firmware? The camera interface is very primitive. List of recent running programs looks like a bare Android.

Here are some more screenshots of the battery menu:

This is what the settings menu looks like:

In general, everything is simple and functional, it doesn’t even have its own themes like the Cyanogen Mod, but over time, I hope the developers will fix this. All that remains is to decide main question, how to install all this? Yes, so that the smartphone does not turn into a “brick”?

Install LineageOS firmware on SGS3

Now we come to the most important thing. If you already have it installed custom recovery, for example TWRP, then everything is very simple. Let's do everything in order and without fuss:

1.Download and copy the firmware to the smartphone, to the memory card (Micro SD Card) in the root directory. Download the appropriate versions of Android Gapps and copy the Gapps to your smartphone, to a memory card (Micro SD Card) in the root directory.

2. Turn off the smartphone

3. Simultaneously press the “volume+”, “home” and “power” buttons, when the Samsung Galaxy S3 logo appears, release the buttons, and after a few seconds we get to the main recovery menu.

4.Select “cleaning”, then “selective cleaning”

5. Check the items Dalvik/ART Cache, Cache, Sistem, Data. Item “Int. The memory “can also be cleared, but not necessarily. IMPORTANTLY DO NOT CHECK THE “Micro SD Card” CHECK!

6. With a casual swipe to the right, we give the command to clean.

7.After successful cleaning, we return to the main menu and select the “Install” item, then the item (parent directory) and finally we reached the “external_sd” item. Click it and select the file with the firmware.

8. Swipe to the right again and wait for the firmware to finish. Upon completion of this operation, you will be prompted to clear Dalvik and Cache. This can be done, but it can also be ignored.

9.Select the “Install” item again, then the (parent directory) item and the “external_sd” item. Click it and select the file with Gapps.

10. Swipe to the right to confirm the installation.

11. After installing Gapps, you can agree to clear Dalvik and Cache one more time and then, in the main menu, select “Reboot” and click on the “System” button.

The download process will take quite a long time. When everything is installed, you will be asked to select a language, set the time and enter your Google account. After that, you can familiarize yourself with and evaluate LineageOS.

Among the dozens of smartphone models produced annually by one of the market leaders - by Samsung - Special attention attracted by the manufacturer's flagship devices. As for the software part of Samsung flagships, here we can talk about the widest possibilities for its changeability. Let's consider in this aspect Samsung model GT-I9300 Galaxy S III - methods for flashing the device will be discussed in the material below.

A high level of performance and a large performance reserve, thanks to the use of the most advanced achievements in the industry, make it possible to easily use Samsung's flagship solutions for many years, without a critical drop in performance. Only the software part of the device requires some attention. However, for interaction with system software, up to its complete replacement, there are convenient tools and proven methods.

All manipulations according to the instructions below are carried out by the user at his own peril and risk. The author of the article and the Site Administration do not guarantee the achievement of positive results desired by the owner of the device, and are not responsible for possible damage to the smartphone as a result of incorrect actions!

To carry out the process of reinstalling system software in the Samsung GT-I9300 Galaxy S3 as quickly and efficiently as possible, it is necessary to carry out several preparatory procedures. This issue should be given due attention, because only after proper preparation you can count on positive result firmware and quick elimination of errors that may appear when installing Android into the device.

Drivers

Almost all procedures that involve serious intervention in the system software of an Android smartphone require the use of a PC and specialized utilities as tools for manipulation. Therefore, the first thing you should take care of when you need to flash the Samsung GT-I9300 is the correct pairing of the device and computer, that is, installing drivers.

USB Debugging mode

In order for Windows applications to interact with the software components of the smartphone, a special mode must be activated on the device - « USB Debugging» . This option will need to be enabled for almost any manipulation that involves accessing data in the phone’s memory. To enable the mode, do the following:

Root rights and BusyBox

Without obtaining Superuser rights, serious interference with the software of the Samsung GT-I9300 Galaxy S III is impossible. At the preparatory stage, root rights will make it possible to create a full-fledged backup, and in the future they will allow you to carry out almost any manipulation with the system software, up to its complete replacement.

To obtain privileges on the model in question, one of the software tools is used: or - these are the fastest and simple remedies, with which you can easily root your device. Choice specific application remains up to the user, in general they work equally efficiently and are easy to use.

In addition to root rights, many operations with the Galaxy S3 GT-I9300 model require the device to have installed
BusyBox is a set of console utilities that allow you to perform manipulations that require connecting additional OS kernel modules. The installer that allows you to get BusyBox is available in .

Backup

Theoretically, after installing the drivers to perform manipulations with the Samsung GT-I9300 Galaxy S III through programs for interacting with memory partitions, there are practically no obstacles left, you can begin Android installation, but, as you know, this process may not always be error-free and can lead to damage to individual software components of the device, not to mention the fact that all user data will be deleted as a result of the procedure and it will be necessary to restore everything necessary - contacts, photos, applications, etc. etc. In a word, it is highly not recommended to start reinstalling Android without a preliminary backup.

User data

To save information accumulated in the phone’s memory during operation, the easiest way is to use Samsung’s proprietary Smart Switch tool, which was mentioned above when describing the driver installation process. We do only three simple steps and all information will be archived in backup copy:

It should be noted that restoration from a backup created using Samsung proprietary software will only be possible on a smartphone running official firmware. If you plan to switch to a custom one or want to additionally insure yourself against data loss, you can use one of the instructions for creating backup copies offered in the material at the link below:

EFS partition

An extremely important system memory area of smartphones is "EFS". This section contains the device serial number, IMEI, GPS identifier, MAC addresses of Wi-Fi and Bluetooth modules. Damage or removal "EFS" in the process of manipulating system partitions By various reasons will lead to inoperability network interfaces, and in some cases, the inability to turn on the phone.

For the model in question, creating a backup "EFS" before reinstalling the system software is not just a recommendation, but a mandatory requirement! Ignoring the operation to create a dump greatly increases the risk of getting an inoperable smartphone!

In order to always be able to quickly restore the partition "EFS" in Samsung Galaxy S3, let's create an area dump using a specialized software tool – EFS Professional.

Recovery "EFS" tab is used "Restore" in EFS Professional. After connecting the smartphone in the same order as when creating a backup, and going to the recovery section of the program in the list "Select a backup archive to restore" you need to select a backup file, check for checkboxes in the field "Archive Backup Contents" and by pressing the button "Restore", wait for the procedure to complete.

Firmware

One of the notable features of Samsung flagship devices is the presence of simply a huge number of modified unofficial firmware. The use of such solutions makes it possible to completely transform shell software and get new versions of Android. But before moving on to installing custom ones, you should study the methods for installing official versions of the system. In case of problems, this skill will allow you to restore the model software to its original state.

Method 1: Smart Switch

The Samsung manufacturer has a fairly strict policy regarding interference with work software own brand devices. The only thing it allows you to do in relation to Galaxy firmware S3 is officially an update to the system version through proprietary Smart Switch software, which we have already used above when installing drivers and creating a backup copy of information from a smartphone.

Install and launch Smart Switch. We connect the smartphone running Android to the USB port of the computer.

After the model is determined in the application, the version of the system installed on the phone is automatically checked against the version available on Samsung servers, and if an update is possible, a corresponding notification is displayed. Click "Update".

We confirm the need to start updating the phone system version - button "Continue" in the request window that appears with the revision numbers of the installed and available system software.

After reviewing the conditions under which the update is successful, click "Everything is confirmed".

Next, Smart Switch will carry out the necessary manipulations automatically, reporting what is happening in special windows with progress indicators:
After receiving confirmation that the OS update has been successfully completed in the Smart Switch window

Samsung GT-I9300 Galaxy S3 can be disconnected from the USB port - all system software components are already optimized.

Method 2: ODIN

Using a universal tool for replacing system software and restoring Android in Samsung devices– most effective method manipulation. The application allows you to install official firmware two types - service and single-file, and installing the first version of the package is one of the few ways to “revive” a Galaxy S III that is not functional in terms of software.

Before using ONE to overwrite memory partitions of the Samsung GT-I9300, we recommend that you read the instructions for reinstalling the system software using the application in the general case from the material available at the link:

Service package

A special type of system software package used in service centers and intended for installation in Samsung Android devices via ONE was named "multi-file firmware" due to the fact that it includes several system component files. You can download the archive containing the service solution for the model in question using the link:

We transfer S3 to Odin mode. For this:
We launch ONE and connect the phone to the USB port. We make sure that the device is identified in the program as filled blue fields with the number of the COM port through which the connection is made.

We add to the program the components of multi-file firmware from the folder obtained as a result of unpacking the archive downloaded from the link above.

To do this, press the buttons one by one and specify the files in the Explorer window in accordance with the table:

After loading all software components into the program, window ONE should look like this:
If you plan to re-partition the device’s memory, specify the path to the PIT file on the tab "Pit".

It is advisable to carry out re-partitioning only in critical situations and when errors occur during the work of ONE without a PIT file! Initially, you should try to reinstall Android by skipping this step!

Press the button "PIT" on the tab of the same name in ODIN and add the file "mx.pit", present in the catalog with the proposed package.

When using a PIT file in a process reinstalling Android on Samsung GT-I9300 tab "Options" ODIN must be checked "Re-Partition".

After making sure that all files have been added to the appropriate fields and the parameters are set correctly, click the button "Start" to start transferring files to the device’s memory.

We are waiting for ONE to overwrite areas of the smartphone’s memory. Interrupting the process is unacceptable, all that remains is to watch the progress indicators in the flasher window and, at the same time,

on the S3 screen.

After the display of ongoing processes in ODIN displays "PASS",

The device will reboot and the OS components will be initialized.

The Android installation is complete, and in the end we get it cleared of the remnants of the previous one. operating system device,

which demonstrates the same level of performance as when first turned on after purchase.

Single-file firmware

If you need to simply reinstall Android, update or roll back the version of the official Samsung GT-I9300 OS, a single-file package is usually used. You can download the latest version of the official OS for Russia to install it via ONE using the link:

Installing such a solution is much easier than a service solution. It is enough to follow the same steps as in the instructions for working with a multi-file package, but instead of points 3 and 4, you need to do it using the button "AP" adding a single file *.tar, contained in the directory obtained as a result of unpacking the archive with single-file firmware.

Method 3: Mobile ODIN

Many users of Android devices are interested in the possibility of reinstalling the OS on the device without using a PC. For Samsung GT-I9300 this action can be done using the Mobile ODIN tool - an Android application that allows you to seamlessly install official single-file firmware.

You can get the tool on your device by downloading it from the Google Play Market.

Successful execution of Mobile One functions is only possible if the device is rooted!

The software package used in the example below can be downloaded from the link:

Install Mobile One and place the package that will be installed in internal memory Galaxy S3 or to a memory card installed in the device.

We launch the application and provide Mobile ODIN with root rights.

Loading additional components MobileOne, providing the ability to install packages with system software. You will be prompted to update the first time you run the tool. Confirm the need to download add-ons by tapping the button "Download" and wait for the installation of the modules to complete.

Before installation, the firmware file must be uploaded to Mobile ODIN. Scrolling through the list of options on the main screen of the application, find and click "Open file...". Select the storage where the firmware was copied, then specify the file intended for installation.

If you are rolling back the system version, you must first clear the device’s memory partitions. To do this, check the checkboxes "Wipe data and cache", and "Wipe Dalvik cache".

In the case of an update, data cleaning may not be necessary, but performing the procedure is recommended, as it allows you to remove “software junk” from the system, and also prevents the appearance of many errors during the installation of Android and its further operation!
Click "Flash" and confirm the application requests that appear.

Mobile Odin carries out further manipulations without user intervention. The latter can only observe:

After the welcome screen appears, carry out initial setup OS parameters.

Everything is ready for using Samsung GT-I9300 Galaxy S III running reinstalled official Android.

Method 4: Custom firmware

The above methods for installing official versions of Android in Samsung S3 allow you to bring the device into factory condition and solve a lot of problems that arise for various reasons while using a smartphone. If the purpose of the device firmware is complete transformation software part, introducing new functions to the device and turning the phone into a truly modern, at least in terms of OS version, device, you should pay attention to the possibility of installing one of the custom firmwares.

Since the level of popularity of the model in question is extremely high, a a large number of various unofficial system software solutions based on Android versions KitKat, Lollipop, Marshmallow and Nougat. The most popular modified shells for S3 are discussed below, and their installation can be divided into two stages - equipping the smartphone with a modified recovery, and then directly installing the unofficial Android.

Installation, launch, configuration of TWRP

In order for it to be possible to install a modified unofficial OS on the model in question, the device must be equipped with a special recovery environment - custom recovery. Several solutions are available for the device in question, including updated version Philz Touch, but it is considered the most functional and convenient product today, and it should be installed to get results, as in the examples below.

For all flagship Samsung solutions TeamWin has officially developed and released recovery packages that can be installed using several methods. Two of them have already been described in articles on our website.

To transfer TWRP to the device’s memory, you can use the ODIN program or the MobileOdin Android application. The process is similar to installing single-file firmware.

The TWRP package used for installation can be downloaded from the link below or at.

Official method Installing TWRP using the Android application is the most preferable solution, described in the material at the link below. In addition to the process of installing the environment, the article describes the main methods for installing firmware using the tool:

Image *.img, as a result of writing which to the corresponding memory section through Official TWRP App S3 will be equipped with a custom recovery environment, downloaded from the official website of the developer. And you can also use the link:

Launching TWRP after the environment has been brought into the device using one of the methods described above is carried out by pressing keys on the switched off device "Volume+", "Home" And "Inclusion".

You need to hold the buttons until the boot recovery logo appears on the device screen.
After booting into the modified recovery environment, you can select the Russian interface language, and then slide the switch "Allow changes" to the right.

At this point, the recovery setup is complete, TWRP is ready for use.

In an effort to get the Samsung GT-I9300 latest versions Android, many device owners ignore the possibility of using one of the most beautiful and functional shells for the device in question - MIUI. Meanwhile, exactly this product considered one of best solutions, despite the fact that it is based on Android 4.4, which is losing its relevance.

MIUI packages intended for installation in the model in question are also available on the websites of well-known development teams miui.su and xiaomi.eu.

Hello, today let me show you how to flash Samsung GT-I9300 Galaxy S3 standard firmware and rooted (or rooted?). Since the amount of information on this device is quite large, I decided that service codes, custom firmware and backup of this model I’ll tell you next time. Everyone already knows what kind of beast this is - there are a lot of reviews and reviews on the Internet.

Initially, the device was supplied with Android version 4.0.4 “Ice Cream Sandwich”, they still deliver them with this old software, but you can already update it to version 4.1.2 “ Jelly Bean", they also promise an update to version 4.3 at the end of the year - we’re still waiting. Initially, in the first versions, the device was wildly glitchy, froze, turned itself off, applications stopped working (processes were terminated urgently), lost the network and stupidly died - it turned off for no particular reason and would not turn on again - on servers they stupidly changed the boards under warranty (who was lucky) and They explained that this was a factory defect, but about a year later the situation leveled out and there were fewer such jambs, which Samsung engineers could correct.

The main drawback of this device today is its fragility - if you pressed or squeezed a little and God forbid you dropped it - a crack in the sensor is guaranteed, and this is a replacement display module entirely (up to 8,000 thousand rubles for repairs in some sharashkas). So be careful. And let's get started with the firmware.

ATTENTION!!! Before starting software updates, rooting, resetting settings and other manipulations with your own or, God forbid, someone else’s device HIGHLY RECOMMEND read this one. In short, you have been warned and don’t say later that this is the first time you’ve heard this.

Samsung GT-I9300 Galaxy S3 - software update and ROOT rights.

Before we start flashing the firmware, let's first prepare everything we need:

Let's fully charge the battery;

MicroUSB Any cable will do, but it’s better to take one from the kit;

Firmware, latest version -I9300XXUGOE1 ;

Flasher program - Odin3 v3.04 ;

Drivers - install kies (when updating the software, do not run this application, or better yet, go to the task manager and kill all processes called kies). But it’s better to install the drivers there and post about how to install them correctly;

A medium-configuration personal computer or laptop with the WIN7 SP1 operating system should be enough;

CF-Auto-Root-m0-m0xx-gti9300.tar - firmware file for rooting.

First, back up all your data or use KIES to save everything necessary files on computer. Soon there will be an article on how to backup the firmware - I’m already writing it. You can download all files at the end of the article.

Samsung GT-I9300 Galaxy S3- factory firmware.

Step 1:If you have not yet charged the battery, then it’s time to do it, insert the battery into the phone and enter the device into DOWNLOADING mode - to do this, first press and hold HOME button(central), then the volume down key and then the power button.

Step 2:Information will appear warning us about possible problems with the phone when using modified firmware. And it offers to either continue or restart the smartphone. Continue pressing the volume up key. A green android robot should appear. We are on the right track.

Step 3:Download the archive with the firmware and flash driver and launch the application Odin3_v3.04.exe.

Step 4:The main window of the flashing program appeared in front of us Odin3 v3.04.

Step 5:And so, the smartphone is entered into download mode, the battery is charged, important information saved, drivers installed (do not forget to “kill” all Kies processes if you installed it). We connect the cable to the phone - the com port should be detected and a line with the word Added will appear - this is a good sign, it means that the device has been detected by the PC.

Step 6:Now it’s time to configure ONE - selecting firmware files:

PIT -mx.pit

Bootloader - BOOTLOADER

PDA - CODE _I9300XXEMG4_1314436_REV00_user_low_ship.tar.md5

PHONE - MODEM _I9300XXEMG4_REV02_REV04_CL1360150.tar.md5

C.S.C. - C.S.C. _OXE_I9300OXEEMH1_CL1359224_REV00_user_low_ship.tar.md5

BE CAREFUL - CHECK SEVERAL TIMES!!!

If everything is fine, press the START button.

Step 8:"PASS"- in about five minutes the device will be flashed. All, Samsung GT-I9300 Galaxy S3 ready to use. You latest version firmware.

Step 9:Reboot and check the software version by typing the following code on your phone keypad *#1234# .

Obtaining ROOT rights.

If you still decide to root your Samsung GT-I9300 Galaxy S3, it means you are aware of what you are doing and take full responsibility upon yourself. And so let's get started:

Step 1:Download CF-Auto-Root-m0-m0xx-gti9300.tar - This is a rootkit, so you will need to disable your ANTI-VIRUS, unzip this archive. Final file must have extension .tar or .tar.md5.

Step 2:We switch the device to DOWNLOADING mode - see the instructions above.

Step 3:Let's launch application Odin3 v3.04.exe.

Step 4:Select the rootkit file and put it in the field PDA. If you have version androida 4.1.x, then be sure to uncheck Auto-reboot.

Step 5:We connect the phone with a cable to the computer and press the Start button. In a minute, the device will flash, and since we unchecked Auto-reboot- turn off the device manually and enter it into recovery mode by holding the volume up button in turn, then the HOME button and the power button. Root rights are automatically installed.

For the current generation of people, the smartphone has become an indispensable assistant and an extremely useful apparatus that combines hundreds various functions. Taking a photo, counting the number of ingredients, setting reminders, checking the weather, reading the news, chatting with friends - this is not a complete list of everything that you can do. modern smartphones. Sometimes we simply forget that they do not last forever and are subject to gradual wear and tear.

Smartphones running operating system Android systems have long filled the whole world with their diversity. Their program code open and ready to edit or improve. While using such devices, there are times when the software component malfunctions and the smartphone stops working properly.
