Samsung's flagship S-series smartphones, released annually by Samsung, are characterized not only by a high level of technical performance, but also by a very long lifespan. Below we will talk about the firmware Samsung Galaxy S 2 GT-I9100 - a phone that is considered an "old man" by the standards of the world of Android devices, but at the same time continues to perform its functions at a decent level even today.
Of course, the efficient operation of any Android device is possible only if its software part is in good condition. If with operating system there are problems, in most situations the firmware will help, which in the case of the Samsung Galaxy S2 (SGS 2) can be performed in several ways. Despite the fact that the methodology for reinstalling Android on the Galaxy S 2 model has been repeatedly applied in practice, and strict adherence to the instructions below practically guarantees the smoothness of the processes and their positive result, do not forget:
The user performing operations with the smartphone is solely responsible for possible damage to the device as a result of incorrect actions, software failures and other force majeure circumstances that may arise in the process of following the recommendations below!
The successful execution of almost any work largely predetermines the correct preparation of the facility for operations, as well as the tools that may be needed. With regard to the firmware of Android devices, this statement is also true. To quickly and easily reinstall the OS and get the desired result (type / version of Android) on the Samsung GT-I9100, it is highly recommended to carry out the following preparatory procedures.
Drivers and operating modes
For the interaction of the computer and utilities with the internal memory of Android devices, it is necessary that the operating system of the PC be equipped with drivers that allow the Windows OS to "see" the smartphone, which is in specialized modes and connected to the USB port of the computer.
Download the app installer from GT-I9100 official technical support web page from the link below. Select the version to download 2.6.4.16113.3 .
Install the tool following the instructions in the installer. After Kies is installed, all the necessary drivers will appear in Windows to manipulate the phone using a PC.
Among other things, the Kies program can be used for many operations with the GT-I9100, for example, saving data from the phone.
If, for any reason, you do not want to install Kies or you are not able to, you can use the driver package, which is distributed separately. Link to download the component installer "SAMSUNG_USB_Driver_for_Mobile_Phones.exe" for the model in question:
Switching modes
To seriously interfere with the internal memory of an Android device where OS components are installed, it is often necessary to switch the device into special service states. For Samsung GT-I9100, this is the recovery environment (recovery) and software download mode ( "Download", "Odin-mode"). In order not to return to this issue in the future, let's figure out how to start the device in the indicated modes at the preparation stage.
Factory reset, official software update
All methods of reinstalling the OS on the Samsung Galaxy S2 GT-I9100, suggested below in this material, except for cases when recovery of the crashed Android is required, assume that the device is initially running the official system of the latest version released by the manufacturer - 4.1.2 !
Restoring the settings to the factory values \u200b\u200band clearing the memory of the device from the information contained in it allows you to get rid of the software "garbage" accumulated during the operation of SGS 2, the effects of viruses, "brakes" and system freezes, etc. In addition, installation of the system software in a cleared The user experience device is very often much more efficient in terms of performance levels when used later.
In a word, before manipulating the SGS 2 system software, follow the procedure for returning the device to the factory state and update the official OS to latest version... For many users of the model in question, by the way, following the instructions below is enough to get the expected result - a smartphone in an out-of-the-box state with respect to the software part and running the latest version of the official Android.
- In any way, copy important information from the device to a safe place (some methods of archiving information are described below in the article), fully charge its battery and start the device into the recovery environment mode.
- Select in recovery "Wipe data / factory reset", then confirm the need to erase the information - item "Yes ..."... Wait for the cleaning procedure to complete - a notification appears on the screen "Data wipe complete".
- Restart your phone by selecting the option in the recovery environment "Reboot system now", wait for the Android welcome screen to appear and define the main operating system settings.
- Make sure the latest version of the official system is installed (4.1.2). Follow the path "Settings" - "Phone information" (at the very bottom of the list of options) - "Android version".
- If for some reason the Android update has not been carried out before and the installed build number is below 4.1.2, update. It is very easy to do this:
- Connect the device to wi-Fi networks and go along the path: "Settings" - "Phone information" - "Software Update".
- Click "Refresh", then confirm that you have read the Samsung System Software Terms of Service. Next will start automatic loading update, wait for the download of components to complete.
- After the notification about the completion of the download of the update package appears, make sure that the battery of the device has a sufficient battery level (more than 50%) and press "Install"... Wait a little, the smartphone will automatically reboot and the installation of the updated OS components will begin, which can be monitored using the filling progress bar.
- At the end of the installation of the updated Android, the device will automatically reboot again, and upon completion of the initialization of the components, all applications will be optimized,
and you will get the latest OS from SGS 2.
- Connect the device to wi-Fi networks and go along the path: "Settings" - "Phone information" - "Software Update".
It may be necessary to repeat the update procedure several times until a situation occurs when, when selecting an item "Refresh"on the way "Settings" — "About device", a notification will appear « Latest updates already installed ".
Root-rights
The Superuser privileges obtained on the GT-I9100 smartphone allow you to perform a lot of actions not documented by the manufacturer with the system software. In particular, a user who has received root rights can clear the official Android of preinstalled system applications that cannot be removed by standard methods, thus freeing up space in the device's memory and speeding up its operation.
In the aspect of changing the system software, root-rights are important primarily due to the fact that only by using them can you make a full-fledged backup before serious intervention in the system software of the device. There are several methods for obtaining Superuser rights. For example, it is effective for the model to use the KingRoot application and the instructions from the article:
Rooting the S 2 model from Samsung is also possible without using a computer. To do this, you can refer to the functionality of the Framaroot program, following the recommendations from the material available on our website:
An equally effective method of obtaining Superuser privileges is to install a specialized zip package "CF-Root" using the recovery environment that developers equip their devices with.
Backup, IMEI backup
Getting a backup copy of the information contained in a smartphone before starting to interfere with its software part is an important step, because the data stored in smartphones is often very valuable for their owners. Saving user information, apps, and more from the Galaxy S 2 can be done in different ways.
Archiving user information
In addition to tools from third-party developers designed to archive information and listed in the material at the link above, users of the model in question who prefer official means of manipulation and do not plan to switch to custom firmware can use the aforementioned Kies software to backup data.
In this option, act by analogy with other Samsung devices, repeatedly reviewed in articles on our resource. For instance:
EFS area backup
A very important action that must be taken before interfering with the system sections of the Samsung S2 memory is saving a backup copy of the IMEI. The loss of this identifier during the reinstallation of Android is not such a rare case, which leads to the inoperability of the mobile network. Restoring IMEI without backup is rather difficult.
The identifier itself and other settings of the radio module are stored in the system memory of the device, called "EFS"... The dump of this section is essentially a backup of the IMEI. Consider the simplest way protect the device from unpleasant consequences.
Your phone must have a MicroSD card of any size!
In this way, a backup copy of the most important system memory area of \u200b\u200bthe SGS 2 will be saved on the removable storage device. You can additionally copy the resulting storage to a secure storage location, for example, on a PC disk.
Firmware
Performing the above preparatory steps in most cases is enough for safe and quick installation of the desired Android version in Samsung GT-I9100. Below we describe the most effective methods of carrying out operations on the model in question, which allow you to completely reinstall the official system, restore the device from the "brick" state, and even give the phone a "second life" by equipping it with a modified OS from third-party developers.
Method 1: Odin
Regardless of the state of the Samsung GT-I9100 system software, reinstalling the official assembly of the phone operating system in most cases can be done using the Odin application. This tool, among other things, is most effective when the device is "sprinkled", that is, in a situation where the smartphone does not boot into Android and the reset through recovery does not help.
Single file firmware
The simplest and safest operation performed through One is the installation of the so-called single-file firmware. By following the instructions below, the user is able to install the official system of the latest version released by the manufacturer into the phone in question - Android 4.1.2 for the region "Russia".
- Download the latest version of Odin from the link from the application review article on our resource, unpack the resulting archive into a separate folder and run the application.

- Mobile One will carry out further manipulations automatically - the smartphone will reboot twice, and as a result, the reinstalled Android will be launched.
- Additionally. After completing the above steps, you can overwrite the CSC section - the image file containing the name of this area in the name contains information about the regional binding of the firmware. The action is performed in the same way as installing the Android single-file package, only you can do without cleaning the partitions and after selecting the option "Open file ..." in Mobile Odin, you must specify the path to the file with the name "CSC ...".
Method 3: PhilzTouch Recovery
Owners of, frankly, outdated Android smartphones are most interested in custom firmwares. For Samsung S2 GT-I9100, a huge number of solutions have been created that make it possible to get new ones on the device. android version... Some software products that deserve attention and are generally suitable for everyday use on the model are discussed below in the article.
Most of the unofficial OS assemblies for the device in question are installed using a modified (custom) recovery. Consider the process of equipping a smartphone with a custom OS using PhilzTouch Recovery - an improved version of CWM Recovery.
Equipping the PhilzTouch Recovery Device
Before using the described tool for SGS 2 firmware, the modified recovery must be installed in the phone. The easiest way to do this is to install a custom zip package using the factory recovery environment.
Installing modified recovery images found on the Internet without a custom kernel can damage the device during further operation of the recovery environment!
Installing custom Android 4.4
Custom OS, which is based on Android KitKat, are some of the best solutions for this device in terms of the ratio of features / performance. For example, the popular Android MIUI shell is available for installation on Samsung GT-I9100 and is successfully used by many device owners.

Installing custom based on Android 5.1
The transition from the fourth version of Android to newer OS versions is carried out by a slightly different method than the one described above, and for a positive result, additional manipulations will be required with the markup of the device's internal memory and the system kernel.
Following the instructions below, you can install a custom solution CyanogenMOD 12.1. For other Lollipop based shells, the kernel used and the procedure may differ!
Step 1: Re-partition the SGS 2 memory
Since in Android, starting from the 5th version, the Dalvik application runtime was replaced by ART, to install new versions of the OS in old devices, it is very often required to redistribute the volumes of system memory partitions (re-partitioning). To perform the operation on Samsung Galaxy ES 2, you need to reflash the device through Odin using a specialized three-file package with the OS and a modified PIT file.
Before starting the re-partitioning, remove the memory card from the smartphone!
- Download the three-file firmware with integrated root-rights from the link above, unpack it into a separate directory.
- Follow the first three steps of the instructions for installing the service firmware from the description "Method 1: Odin" above in this article. To load into the program, use the files from the directory "ROOT_I9100XWLSE + PIT4GB" with a modified three-file system!
- Open the tab "Pit", click "OK" in the risk warning prompt window.
Click "PIT" and in Explorer specify the path to the file "I91001GB_4GB.pit"located in the folder with the three-file modified package.
- Go to the tab "Options" in Odin and check if the checkbox is checked "Re-Partition"... Next click "Start" and wait for the end of the re-partitioning, as well as the installation of the official OS with integrated root-rights.
- If, at the end of the processes by the program, the smartphone automatically reboots into factory recovery, disconnect the device from the PC, select the item in the recovery environment "Wipe data / factory reset", confirm the need for formatting by selecting the item "Yes ...", wait until the cleaning procedure is completed and restart the device by selecting in recovery "Reboot system now".

If the above notification is missing, go to "Settings" — "Memory" and tap "Format USB stick", press the button to start cleaning and wait for it to complete.
Upon completion of the procedure for clearing the internal storage, the SGS 2 memory re-partitioning will be completed. You can make sure that the volumes of the partitions have been redistributed successfully by going to the following path on your smartphone: "Settings" - "Memory"... The picture should match the screenshot:
Step 2: Install CyanogenMod 12.1
After the internal drive of Samsung GT-I9100 is re-partitioned, there are no obstacles to installing the modified firmware based on Android 5.1 into it. You will need four zip files: two of them contain custom kernels and recovery images, the third contains a package for equipping Android with Google services, and, finally, the CyanogenMod 12.1 shell itself of the latest version for the device in question. Everything you need is packed in an archive, which can be downloaded from the link:
- Unzip the package downloaded from the link above and copy the resulting directory containing four zip files to the MicroSD card installed in SGS 2.
- Reboot into native recovery, install the kernel and custom environment package in exactly the same way,
as described above in section "Equipping the PhilzTouch Recovery Device" of this article.
- Reboot Samsung ES 2 into the modified PhilzTouch Recovery environment and follow the steps in the instructions "Installing custom based on Android 4.4.4" above in the article. That is, create a backup and format the partitions.
- Without restarting PhilzTouch Recovery after cleaning (this is important!), Install the zip package "CWM_i9100_6.0.5.1.zip"... The path is as follows:
- From the PhilzTouch Recovery home screen, open "Advanced", select the first function in the list - "Reboot Recovery"and then tap "Yes - Root device"
- As a result of the previous step, the smartphone will reboot into CWM Recovery 6.0.5.1.
It is very simple to work in this environment - you move through the menu items using swipes up and down, select an option - swipe to the right, return to the previous menu - swipe to the left.
