Stages of preparation

To carry out the process of reinstalling the system software on the Samsung GT-I9300 Galaxy S3 as quickly and efficiently as possible, several preparatory steps are required. This problem should receive due attention, because only after proper preparation can we expect a positive result of the firmware and a rapid elimination of errors, the appearance of which is possible when installing Android on the device.

Drivers

Almost all procedures that involve serious interference with the system software of an Android smartphone require the use of a PC and specialized utilities such as manipulation tools. Therefore, the first thing to consider when you need to flash the Samsung GT-I9300 is the correct pairing of the device and the computer, that is, the installation of the drivers.

Equipping the system components allows the program to see the smartphone and interact with it, in the easiest way, using the package-avtoinstallyator "SAMSUNG_USB_Driver_for_Mobile_Phones" drivers to flash a Samsung GT-I9300 Galaxy S III smartphone
- - the file from the link above, unzip it and run the installer;
- - Double click the button "Following" in the drop-down windows and then in "Installation" ;
- We are waiting for the completion of the installer, after which all the necessary drivers will be present on the system.
The second way to equip the operating system with drivers for Samsung S3 is to install proprietary software offered by the manufacturer to interact with Android devices of its own brand: Smart Switch.

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 should be used for almost any manipulation that involves accessing data in the phone's memory. To enable the mode, do the following:

We activate the "Developer options" following the route "Settings" - "About device" - five clicks on registration "Build number" until the message appears "Developer mode is enabled" ;
Open section "Developer options" on the menu "Settings" and check the checkbox to enable debugging mode. We confirm the action by touching "Yes" in the warning window.
When you first connect a debugging-enabled device to a PC, a request to a fingerprint will appear, requiring confirmation to continue working. To prevent the window from disturbing the every time a debugging-enabled device connects, turn on the check box "Always allow debugging from this computer" and only then click "Yes" .

Route rights and BusyBox

Without obtaining super rights, it is impossible to seriously interfere with the software part of the Samsung GT-I9300 Galaxy S III. At the preparatory stage, root rights will allow you to create a full backup, and in the future will allow you to do 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: KingRoot or KingoRoot - these are the fastest and simplest means by which it is easy to root the device. The choice of a specific application is up to the ; generally they work just as efficiently and are easy to use.

King Root or KingoRoot using the corresponding program review article link on our website.
We follow the instructions that describe the process of obtaining super rights using the selected tool.Read more:

In addition to root rights, many operations with the Galaxy S3 GT-I9300 require the installation of
BusyBox on the device, a set of console utilities that allow manipulations that require the connection of additional operating system kernel modules. The installer that allows you to get BusyBox is available on the Google Play Market.

and install the application from the link above and then launch the tool.
We provide the tool "BusyBox Free" with root rights, wait for the application to complete the system scan and click "Install" .
Once the installation is complete, the tab opens «About BusyBox» and you can make sure the components are installed by going back to the section «Install BusyBox» .

Theoretically, after installing the drivers to perform manipulations with the Samsung GT-I9300 Galaxy S III through programs to interact with memory sections, there are practically no obstacles, you can start installing Android, but, as you know, this process may not be always error-free and can damage the individual software components of the device, not to mention the fact that all data as a result of the procedure will be deleted and you will have to restore everything you need: s, photos, applications, etc. In short, it is discouraged to start reinstalling Android without preliminary backup.

data

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

We launch the program and connect the smartphone to the USB port of the PC.
After waiting for the definition of the device in the app, click on the area "Backup" .
The process of copying data to a backup is done automatically, and all that is required of the is not to interrupt the process.
After the job is finished, a confirmation window appears, listing all the components that have been copied to the PC disk.
The return of information from the backup to the device is also done with practically no intervention in the process and is initiated by pressing the button "Restore" on Smart Switch.

It should be noted that restoring from a backup created with Samsung's proprietary software will only be possible on a smartphone running the official firmware. If you plan to switch to custom or you also want to be safe from data loss, you can use one of the instructions for creating backups offered in the material at the following link:

SAI Section

An extremely important system storage area for smartphones is «SAI» . This section contains the device serial number, IMEI, GPS ID, Wi-Fi MAC addresses, and Bluetooth modules. Damage or removal of «SAI» in the process of manipulating system partitions for various reasons will lead to inoperative network interfaces and, in some cases, the inability to turn on the phone.

For the model under consideration, create a backup «SAI» before reinstalling the system software is not just a recommendation, but a mandatory requirement! Ignoring the operation to create a dump multiplies the risk level of having an inoperative smartphone!

To always be able to quickly restore the partition «SAI» On Samsung Galaxy S3, let's create a dump of the area using a specialized software tool: SAI Professional .

the file with the program from the link below and unzip it to the root of the PC disk system partition.
Open the file EFS Professional.exe , which will lead to the appearance of a window with the choice of the program component to start. Click on "EFS Professional" .
After starting the program, you will be notified that there is no device connected. We connect the device with USB debugging enabled to the PC and we wait for it to be detected in EFS Professional. When a request is received on the smartphone screen, we grant super rights to the tool.
If the device is successfully identified, the EFS Professional logs field will display information about the presence of root rights on the device and the BusyBox present on it. Go to the tab "Backup" .
In the drop-down list "Device filter", select "Galaxy SIII (INT)" , which will lead to completing the field "Lock device" with checkboxed values. We place the marks near the positions «SAI» y "RADIO" .
Everything is ready to start saving the most important sections. We push "Backup" and we await the completion of the procedure: the appearance of the window confirms the success of the "Backup completed successfully."
The resulting dumps from the partitions «SAI» y "RADIO" are saved in the directory "EFSProBackup" located in the folder with the EFS Professional program, as well as in the phone memory. It is recommended to copy the directory with the backup copies in a safe place for storage.

To restore SAI, use la flange 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 file to restore" , select the backup file, check the checkboxes in the field "Contents of the file backup" and click on the button "Restore" , wait for the procedure to complete.

Firmware

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

Способ 1: Smart switch

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

Install and run Smart Switch. We connect the smartphone launched in Android to the USB port of the computer.
Once the model is identified in the application, an automatic verification of the version of the system installed on the phone is performed with the edition available on Samsung's servers, and if an update is possible, a corresponding notification is displayed. Click on "To update" .
We confirm the need to start updating the version of the telephone system: the button "Continue" in the prompt window that appears with the revision numbers of the system software installed and available for installation.
After reviewing the conditions under which the update is successful, click "All confirmed" .
In addition, Smart Switch will perform the necessary manipulations automatically, reporting what is happening in special windows with progress bars:
After receiving the confirmation of the successful completion of the OS update in the Smart Switch window, the Samsung GT-I9300 Galaxy S3 can be disconnected from the USB port; all components of the system software are already optimized.

Method 2: ODIN

Using the universal ODIN tool to replace system software and restore Android on Samsung devices is the most effective manipulation method. The application allows you to install official firmware of two types: service and single file, and installing the first version of the package is one of the few ways to "revive" the inoperable software of the Galaxy S III.

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

Service package

A special type of package with system software used in service centers and intended for installation on Samsung Android devices via ONE was called "Multi-file firmware" due to the fact that it includes several file-system components. You can a file containing a service solution for the model in question by following the link:

Samsung GT-I9300 Galaxy S III firmware service (multiple files) for installation via ODIN

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

We add to the program the firmware components of multiple files from the folder obtained as a result of unzipping the file ed from the previous link. To do this, we press the buttons one by one and specify the files in the Explorer window according to the table:
After loading all the software components into the program, the ONLY window should look like this:
If you plan to re-partition the device memory, specify the path to the PIT file in the tab "Pit" .

It is advisable to re-partition only in critical situations and when errors appear during ONE operation without a PIT file! Initially, you should try to go through the Android reinstallation process, skipping this step!

Presione el botón "PIT" in the tab of the same name in ODIN and add the file "Mx.pit" , which is present in the directory with the proposed package.
When using a PIT file in the Android reinstallation process on Samsung GT-I9300 in the tab "Options" in ODIN the brand must be established "Re-partition" .
After ensuring that all files have been added to the appropriate fields and that the parameters are set correctly, press the start button" to start transferring files to the device memory.
We are waiting for ONE to overwrite the memory areas of the smartphone. Interrupting the process is unacceptable, it remains only to observe the progress indicators in the flashing window and, at the same time, on the S3 screen.
After se show "" In the field of indication of processes in progress in ODIN, the device will reboot and the components of the operating system will be initialized.
The Android installation is complete and as a result we get a clean device from the remnants of the previous operating system, demonstrating the same level of performance as when it was first turned on after purchase.

Single file firmware

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

It is much easier to install such a solution than a service one. It is enough to follow the same steps as in the instructions to work with a multi-file package, but instead of points 3 and 4, you need to use the button "AP" to add a single file * .tar content in the directory obtained by unzipping the file with single file firmware ...

Method 3: Mobile ODIN

Many Android device s are interested in the possibility of reinstalling the operating system on the device without using a PC. For Samsung GT-I9300, this action is feasible using the Mobile ODIN tool, an Android application that allows you to seamlessly install the official firmware from a single file.

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