If your smartphone is several years old and you are already tired of it, is it possible to breathe new life into it? 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 Most users will most likely say that no, the smartphone is outdated, there is not enough RAM, the processor is no longer “cake”, there is not enough built-in memory, and the screen resolution has begun to hurt the eyes.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 look at 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.

You can, of course, carry a portable battery with you everywhere, or constantly keep your smartphone on charge at your workplace, 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 Samsung's early flagships sooner or later encountered the problem of “brakes” on their smartphone. The 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. Last official version Android seems to be 4.2.2 there. 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 thanks to the developers for that too. 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 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 with 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. The list of recently launched programs looks like on 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. It remains to solve the 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 custom recovery installed, 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 corresponding Android versions Gapps and copy Gapps to your smartphone, to a memory card (Micro SD Card) in the root directory.

2. Turn off the smartphone

3.Press the “volume+”, “home” and “power” buttons at the same time when the logo appears Samsung Galaxy S3, 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.

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 I will tell you about service codes, custom firmware and backup of this model 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 updates at the end of the year up to version 4.3 - 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 pinched it a little and God forbid you dropped it, a crack in the sensor is guaranteed, and this means replacing the entire display module (up to 8,000 thousand rubles for repairs in some sharashkas). So be careful. And let's get started with the firmware.

ATTENTION!!! Before you start updating software, 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 do backup copy all data or use the KIES program to save all 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.

After using a smartphone for a long time, in some cases it is necessary to update its software. This will help increase the speed of operation and significantly update the system, somewhat diversify the functions of the device (depending on the type of firmware used). Galaxy S3 is one of the most popular smartphones of its time. However, not all its owners know how to flash S3.

What should you consider before starting the firmware?

In order for the software changes to be beneficial, the following nuances of the process must be taken into account. Before flashing your Galaxy S3, you need to make sure that the battery is charged more than 50%. It is also worth considering that worn-out power supplies will not be able to keep the smartphone on for the required amount of time. Therefore, the firmware must be installed on a device with good block nutrition.

Before you start making changes to the software, you should save all the necessary files from your phone memory. This is because they may be removed during the firmware installation. In addition, a certain amount of free virtual space will be required to copy the necessary new files. ABOUT phone book You should also not forget about the phone memory, as there is a possibility of data loss.

Firmware for the Galaxy S3 can be carried out by almost any smartphone owner who has the skills to work on a laptop computer. But at the same time, you must follow all the rules of the procedure.

Required Software

The following programs will be needed:
1. Odin PC.
2. Recovery clockwork.
3. Firmware for S3.
4. Samsung drivers.
5. A set of Google applications.

After all the software has been downloaded and installed, you can proceed directly to

What can interfere with your work?

Before starting work, you need to turn off antivirus program. This is due to the fact that some files that will be used by programs when installing firmware may be identified by the antivirus as malicious information. In this case, it will block the programs from running. Many users know how to flash a Samsung Galaxy S3 with antivirus on a computer: temporarily suspend protection or add used folders and programs to an exception - there are many ways to limit the operation of such software.

After fulfilling the above not so complex, but mandatory and extremely important conditions, you can continue preparing for installing the firmware on Galaxy phone S3.

Installing programs

To carry out the work you will need Samsung drivers, which will allow you to recognize your smartphone, as well as the Odin PC program. The process of installing them is no different from installing conventional utilities and software: you need to follow all the recommendations and select the necessary items. These programs are necessary and mandatory to complete the intended work. In order to figure out how to flash a Samsung Galaxy S3 without them, you need to have more in-depth knowledge of programming, and also have a good understanding of the phone system itself.

Preparing your phone

To start flashing the software, you need to put your phone in Download Mode:
1. Turn off your phone completely.
2. Simultaneously press and hold the “Power”, “Volume Down” and “Home” keys for a while. This will load a special menu.
3. After this, a warning will appear, at which you should press the “Volume Up” key.
4. An image of a green robot should appear in the center of the screen, which will indicate the activation of the required mode.

Compliance with this item is mandatory. Only in this case is it possible to make changes to the phone software and prepare it for installing new firmware. A similar menu should appear when you hold down the above keys on all original devices of this model.

Installing root rights to make changes

In order to install root rights, you need to run earlier installed program Odin. In the window that appears, click “PDA”, then find the file called “CF-Auto-Root”, after which you can connect the phone to a personal computer. When connected, the ID: COM field should light up blue. If everything went well, you can click on virtual key"Start". The rooting process is usually quick. After its completion, the message “RESET” should appear, and the phone will automatically reboot in the mode for changing root rights. Next, the smartphone needs to be rebooted in normal mode, after which it can be disconnected from the computer. Rooting is necessary to be able to change the software, which is prohibited by the manufacturer.

Installing "recovery"

In order to complete this step, you need to enter the smartphone into Download Mode, for which we perform the above process. Next, launch the Odin program. We connect the phone again to the computer via the original cable, press the “Start” key. Once the process is complete, the phone should reboot.

Firmware installation

At this point, you can directly find out how to flash a Samsung Galaxy S3, since the previous steps were only a preparatory stage.

We will divide the whole process into the following main points:
1. Turn on the phone.
2. Connect it to the computer in storage disk mode for data exchange.
3. Copy to internal memory firmware and set from Google. It is worth remembering that you need to copy all files.
4. Turn off the phone.
5. After turning off completely, press and hold the “Power”, “Volume” and “Home” keys at the same time.
6. After the downloaded recovery, you need to do wipes.
7. Install the firmware as follows: type Install zip from sdcard and find the firmware, type Install zip from sdcard and find the set from Google.
8. Reboot the phone.

If the entire process was completed correctly, a loading animation should appear on the screen. In this mode, the device will boot together with new firmware. It is impossible to flash a Chinese Samsung Galaxy S3 without a set of standard software from the phone manufacturer, but for similar devices you can find other firmware and methods for installing them.

If some of the above recommendations for installing new software were not followed, then there is a possibility of losing the old software. Therefore, during the work you need to be careful, since if the installation of the firmware has been started, then it must be completed without fail. Otherwise, the smartphone will not work.

Fifth generation

If you are the proud owner of a Galaxy S5, we note that the process of flashing its firmware is not much different from that described above. It is worth saying that during the firmware installation, user information (settings, as well as programs) is not deleted - everything that was on the smartphone will remain there even after the device’s firmware process is completed. Remember that if the firmware is unsuccessful, the device cannot be restored without the help of specialists. To avoid such problems, a number of conditions must be observed. First of all, you need to make sure that the smartphone is fully charged. After that, we check the wire through which the firmware will be installed for functionality. Let's make sure that Personal Computer, with which the firmware process will be carried out, functions correctly and does not display “ Blue screens", does not turn off, does not reboot. We carefully study the instructions, only then proceed to the firmware process. The computer will be supplemented with a UPS, which is capable of operating for at least twenty minutes during a blackout.

1. Download everything we need to your computer

Driver SAMSUNG USB Driver for Mobile Phones v1.5.23.0.exe (14.65 MB) or Samsumg Kies (usually a disk with this program is included in the kit, or download the latest version from the official website)

The firmware itself is 4.1.2 I9300XXEMF6 (TMC) (06/27/2013)
Odin PC latest version Odin3_v3.07 (452.87 KB)

2. Then install all downloaded programs in this order:
The first on the list is SAMSUNG USB Driver for Mobile Phones, or completely Samsung Kies, although you will then have to temporarily “kill” the processes associated with the operation of this program through the Windows Task Manager. It’s not difficult to do this; it’s worth stopping everything where the word “Kies” appears.

Disable your antivirus, if you have one (I personally do without it)
Install drivers.

Unpack Odin (check that there are no folders with Cyrillic characters in the path to the program, this is important).
Place the firmware in any folder on your PC, say your desktop (check that there are no folders with Cyrillic characters in the path to the firmware).

3. Transfer the phone to Download Mode
– Turn off the phone completely, wait for it to turn off completely.

– Then, to enter the Download mode (firmware / download mode) of the Samsung GT-I9300 Galaxy S 3 phone, press three hardware buttons at the same time, this is volume down (down) + phone power key + menu button, and hold for a couple of seconds.

Enter download mode Samsung GT-I9300 Galaxy S 3

– After turning on the phone, release the buttons, a warning message with a yellow triangle should appear where they will ask us or we definitely want this, confirm the desire to enter download mode by pressing the “Volume up” (increase) key

– An image of a green robot appears on the smartphone screen, as in the picture.

Flashing mode Samsung GT-I9300 Galaxy S 3

Congratulations, let's move on to the next stage.

4. Odin program and firmware.
Find the downloaded archive with single-file firmware in .zip format and unpack it. We see two files: in .tar or .tar.md5 format.

Run Odin PC as administrator
In the PDA field we indicate the path to our firmware. Let's not touch anything else!

Connecting the phone original cable, which is already in Download Mode to a computer with Odin running and the selected firmware file, the field with the name of the port through which you connected lights up blue.

How to reflash Samsung GT-I9300 Galaxy S 3

Well, that’s all, feel free to click “Start”, and the process of flashing your Samsung GT-I9300 Galaxy S 3 phone will begin

During the flashing process, you will see many changing images in img format; system.img will take the longest to flash.
Then you will see this picture, and the phone will reboot into installation mode.

Afterwards the phone will reboot. It is possible that the Samsung message will hang for a long time (the first turn on after flashing lasts longer than usual, sometimes up to 10 minutes), but usually no longer than a minute.
Next, the phone will boot, you will see the welcome screen, and Odin will show you that everything was successful. The message “All threadscompleted.(succeed1 / failed 0)” will appear in the log.

Instructions for flashing a Samsung Galaxy S3 smartphone using single-file firmware via the Odin 3 program on Windows

Any digital device, be it a player, phone, camera, computer or even a smart watch, will not perform its functions without software. Without software, a computer is just a piece of hardware, so in order not to be just a piece of hardware, install operating system(OS). The phone also has an OS installed, which is popularly called “firmware”. Firmware is a set of hardware settings and software that are located in the device’s memory. So, in this article, let's take a closer look at why people change the firmware on their phone.

If a phone we just bought works great, doesn’t show any errors, “flies” and so on, then a phone that has served us for some time may slow down, work intermittently, be glitchy, have an outdated design, or a manufacturing defect. , do not install applications because the firmware is outdated, and so on and so forth. If in case of brakes it is possible to do full reset phone settings, then when eliminating glitches, defects or unstable operation of the device, it is recommended to update the firmware to a newer version.

Usually Android smartphones themselves offer to update to automatic mode, but there are times when our smartphone is infected with a virus or does not turn on at all or freezes while loading, then in this case we will have to install the firmware ourselves.

1. Preparing and downloading everything you need

Before flashing the phone firmware, you need to download:

1. USB driver for Samsung phones(in our case, we used driver version 1.5.59.0 dated 01/08/2016 called SAMSUNG+USB+Driver+for+Mobile+Phones+1.5.59.0+SSPC.exe);
2. Firmware(we used stock non-camera Android firmware 4.3 XXUGOE1 (SER) (05/21/2015) Changelist 2833503, download);
3. Odin PC program(we used Odin3 v3.09.3).

2. Installing programs

First of all, you need to install the USB driver for samsung phones, then unpack the Odin program into a directory without Cyrillic (Russian) letters, drive C is usually suitable. In the same folder where Odin was unpacked, we throw the firmware, unpack it and see 2 files: the first in the format .tar.md5, the second SS_DL.dll (second dll file can be deleted).

3. Switch the smartphone to Download Mode

To do this, turn off the phone completely by pressing the power button. We wait until the device screen goes off.

4. Odin program and smartphone firmware process

So, now we launch the program by double-clicking on the Odin3 v3.09.exe file. The following window should appear:

In the "Option" section, leave the following checkboxes: "Auto Reboot" and "F. Reset Time". And in the “Files (Download)” section, click on the “PDA” button and select the file with the firmware. After the completed manipulations, connect the cable to the phone, in turn, the blue “ID: COM” label should light up in Odin.

Now the most important thing is to press the “Start” button and wait until the phone is flashed (1-5 minutes). When the phone is flashed in the program, the inscription "PASS" will light up at the top, and at the bottom " All threads completed. (succeed 1 / failed 0)", which means “Everything is just cool and without errors!”, Now we disconnect the cable from the phone, close the program and wait for the android to load on the phone itself.
