How to update galaxy s3 mini from android 5.0 lollipop

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 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 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 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.

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 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

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

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. The final file must have a .tar or .tar.md5 extension.

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.

Samsung produces Cell phones on the base operating system Android. Each new gadget is equipped with a modern version of the operating system. Owners of older devices are recommended to update the software to the latest versions. If you still have old version firmware, then let's look at how to update OS Android on Samsung phone.

The simplest method

It belongs to the list of powers of an ordinary user and does not require deep knowledge, so anyone can do it on their own.

Before making changes, we recommend that you back up your stored data to external storage. It is also important to check the battery charge level. The process is lengthy, so it's worth charging your phone to 80-90% to avoid the update stopping suddenly.

Before the procedure, it is recommended to turn on the Wi-Fi signal to avoid financial losses from your mobile account. When the data is received from the server, go to the “Install” field and wait for a notification that the changes are complete. After the adjustments have been made.

This algorithm described for use on Samsung smartphone galaxy s3. However, the essence remains relevant for all devices.

Update via computer or laptop

You need to install the Kies program. The utility must be licensed so as not to spoil the operating system.

Restoring factory settings

It happens when a person is not satisfied with the expansion. Then they perform a rollback.

How to get rid of the pirated version

Let's say you accidentally installed an unlicensed file and are wondering how to remove the update.

Samsung has officially stopped upgrading the international variant, meaning you can't get the official Android update KitKat. Naturally, when such a thing happens, online communities pick up the slack. And this is very good news, because Samsung, despite a lot of complaints and online petitions, does not seem to want to upgrade its Galaxy S3 to KitKat (even though everyone knows that you can; Android 4.4.4 is designed to run on a 1GHz processor and 512 MB RAM).

ParanoidAndroid is a ROM created by a dedicated team of developers, and the latest (final) version has just arrived for the international Galaxy S3 model, that is, the model designated I9300. Of course, being a custom ROM, the process of installing it on your phone requires you to have root access, which could potentially brick the phone if it goes wrong and void the warranty too.

Still unsure? Here is an excerpt from Android View about the ROM review: “PA3+ is an AOSP based ROM and what I love most is its beauty, especially the hybrid flexibility. ROM performance is fast and responsive, but one thing that still worries me is battery life. Don't expect very decent battery performance from it. Install it, enjoy it, and look forward to a battery leak fix in the future."

We hate to say things like this, but we must emphasize that if you are going to root your phone and install this ROM, then you are doing it at your own risk. We are not responsible if your phone stops working!

Before we begin

1. First of all, it is important to clarify that this software and procedure is for the international variant of Galaxy S3, I9300 only. To make sure you have the correct model, go to Settings > About Phone, where you should see the model number. If it's an I9300, move forward. In addition, the phone must be disconnected from the network.
2. Secondly, it is a good idea to make backups of any important files or data that you might have on board your Galaxy S3 before moving on. You can manually connect your phone to a PC and extract what you need, or you can use a custom recovery tool like ClockworkMod or TWRP - these tools create an entire backup of your phone and you can restore it to the way it was if things go wrong or you change your mind (provided that the phone is not completely bricked, of course).
3. Make sure your computer has updated USB drivers to connect to your phone.
4. Make sure USB debugging mode is enabled on your smartphone. Go to Settings > Developer Options and check the Enable USB debugging" Note that if you can't see Developer Options, you can open them by tapping the software build number seven times.
