How to reflash the Android version on your phone. How to change firmware on Android via computer, preparatory stage

There are times when you need to change software on a mobile phone. This thought makes many people's hair stand on end and their heart rate increase. And in vain, because in fact it is not difficult to do.

Why flash a mobile phone?

Now is the time computer technology and flat smartphones with touch screens. However, despite the technological boom, old push-button mobile phones should not be discounted. The same “bricks”, sliders and “clamshells” that everyone had just a few years ago. Nobody even thought about changing the software on these legendary devices. The question is, why flash them at all?

Firmware updating of a phone (Samsung, Nokia, etc.) can be done for the following reasons:

  • the device software has broken down or started to work worse;
  • to obtain newer software.

Few people have seen such a device crash, but this is quite possible, and there are plenty of reasons for this. In addition, official and independent developers release new firmware versions for these gadgets.

Flashing phone firmware via computer

Before installing new software, there are a few things to keep in mind.

  1. First you need to create a backup copy of all data (contacts, SMS, settings, etc.) on your phone to your computer. This can be done using specialized programs (MyPhoneExplorer and others).
  2. After this, you must charge your mobile phone: at least 80% of the battery, although 100% is better.
  3. It is best to flash the phone firmware via a computer using a laptop. The reason is that it contains a battery, as a result of which, due to an accidental power outage, it will be possible to complete the process started. Otherwise, the consequences could be catastrophic.

For the firmware you will need the following things:

  • of course, the phone is 100% charged;
  • data cable (in most cases USB is used, but some mobile devices require a special data cable);
  • firmware file; it must be downloaded from the Internet, but before that you need to carefully read the information, read comments and reviews, and before that you need to find out the version old firmware: enter the code *#06# on the keyboard (for Nokia there will be a different code - *#0000#);
  • drivers for a mobile device;
  • program for flashing a phone (“flasher”).

Programs

There are quite a lot of utilities for firmware and they are divided into two categories:

  • general ones that are suitable for all models;
  • those that are intended for one manufacturer (for example, the Phoenix program for flashing Nokia phones).

General utilities can flash almost any model. However, if there is a program that is created specifically for a certain brand of mobile devices, it is better to use it, since it already contains all the necessary drivers and, possibly, the OS itself. Here is a small list of “flashing tools” for specific brands that will help “cure” the gadget:

  • for Nokia – Phoenix Service and official service Nokia Software Updater;
  • Sony Ericsson– PC Companion (updated SEUS), unofficial DaVinchi;
  • LG – flashers Speedo, GsMulti;
  • Motorola – Flash&Backup, P2K;
  • Samsung – OptiFlash;
  • BenQ – Winswup, Update Tool.

Let's look at the algorithm using the example of the Phoenix utility.

Flashing Nokia

Before flashing your phone's firmware, you need to download and install the Phoenix utility, which is designed specifically for this brand. In addition to the initial preparations described above, you need to do something else, namely, remove all programs that can somehow be associated with the mobile device (Nokia Software Update, Nokia PC Suite, etc.) and then clear the cache and register. Otherwise, the firmware of the Nokia phone may fail. Also, just in case, you should turn off your antivirus.

Now you need to install Nokia drivers Connectivity Cable Driver and Nokia Flashing Cable Driver. We connect the mobile device to the PC. You can make sure that all drivers are in place in Device Manager. Open computer properties. Then select “Device Manager” and expand the Wireless Communication Devices item. The number of devices should be from four to six.

Connect to your computer (select PC Suite mode) and launch Phoenix. In the Connection item, click Setting. In the window that opens, select Add. Click on the Driver drop-down list, select USB and scan (Scan). Select the device that appears. Click Select. Now from the drop-down list in the Connection item we select required device. Next, go to the File\\Scan Product tab. After scanning, the desired mobile device should appear below. If this happens, move on.

Go to the Flashing section, where you need to click Firmware Update. Now you need to select a code. If we don’t have the slightest idea which one is needed, then we take any one. At the same time, you need to remember one point: if Russian is desired in the phone, then look for the words Russian, Cyrillic or RU in the name of the firmware file. When Product Code is selected, click on Refurbish. Congratulations, flashing your phone via your computer has begun. It will last approximately 7-10 minutes. During this time, you should not touch the phone, cable or the program itself.

Flashtool

If there is no special utility and you need to flash the phone’s firmware via a computer, the Flashtool program can easily handle this if you have the OS file and drivers, which you will need to find yourself.

The work algorithm is as follows. Turn off the phone, remove and insert the battery. Turn on Flashtool program. Click on the lightning icon and leave a dot on the Flashmode item. Next, select the downloaded firmware from the list in the left window and click “Ok”. Afterwards you should see instructions for connecting your smartphone to your PC via a USB cable. We do this, and the program for flashing the phone starts working.

Flashing Android

Mobile devices based on the Android operating system require an OS change much more often than regular mobile phones. The reason for this could be numerous malware, applications downloaded from unknown sources, etc. However, the most basic and most common reason for a smartphone to fail is its owner.

The phone's firmware is flashed via a computer, but you can do without it (in Recovery mode).

Via PC

First you need to make some preparations.

  1. Download special utility for flashing (Flashtool, Bootloader or program from official developer– PC Companion for Sony Ericsson, “Software Update Fly smartphones" for Fly, etc.).
  2. At the same time, download the firmware for specific model devices. In this case, you should definitely familiarize yourself with the characteristics, read comments and reviews. Copy the firmware to the Firmwares folder of the Flashtool program.
  3. Install drivers on the PC.
  4. We make a backup copy of the files from the smartphone, and also copy the contents of the flash drive to the computer (flashing the phone's firmware through the computer will not leave old marks about the location of the files on the flash card, so it will create new ones on top of the old ones).
  5. We find a USB cable, and also do USB debugging (go to “Settings”, find “Developer Features”, then check the “USB Debugging” checkbox).
  6. We charge the device 100%.

Then open the Flashtool utility and go through the algorithm described above.

Without PC

This is done through Recovery mode. To do this, the firmware file must be downloaded and moved to the memory card. Now turn off the smartphone and turn on Recovery. To do this, you need to simultaneously hold down a certain combination of keys (power and volume down, up or menu - the combination depends on the manufacturer). You can find out the exact combination by looking at the device passport. Next, select the item “ Apply Update From External Storage" (the firmware of a Samsung phone and many other Android-based smartphones happens in the same way).

We are working on Windows Mobile

With smartphones on Windows based Mobile things are much simpler. To do this, you will need, in fact, the gadget itself, a USB cable and a Windows program Phone Recovery Tool for computer. First, download this utility from the official website (or via this direct link: go.microsoft.com/fwlink/?linkid=522381, the download will start automatically), install and launch. The program will immediately begin searching for updates, after which it will ask you to connect your smartphone to your PC.

Now the search and installation of drivers for the connected device will begin. If they are not found, you can click on the corresponding button to search on the Internet. When the drivers are installed, a large tile with an image of the connected gadget will appear. By clicking on it, you will start downloading the firmware file. Don't panic if the process takes too long, as the file can weigh around a gigabyte. In addition, if the download is suddenly interrupted, it can always be resumed from where it stopped. There's still one nice moment: If you want to flash your smartphone again, you won’t have to download anything, since the OS will remain on the computer.

When the download is complete, the Reinstal Software button will appear, clicking on which will begin installing the software. At the same time, it is strictly undesirable to touch the phone, USB cable, or turn on/off the computer, since the results of such manipulations can be quite disastrous.

Often, users of mobile gadgets are faced with a situation where the phone they just purchased turns out to be not as ideal as it seemed on the display case. Typical manifestations of problems significantly slow down the operation of the device, and sometimes make it completely impossible. However, no matter how the gadget behaves, these flaws can almost always be removed by flashing it with new software.

How to flash a phone yourself: reasons for updating the software

Phone firmware is necessary in cases where the following symptoms occur:

  • freezing for no reason;
  • spontaneous shutdown of the device;
  • slow response to commands;
  • inability to set the desired ringtone;
  • Unstable operation of Android applications;
  • spontaneous return to default settings.

These are the most obvious indicators that indicate that it is not a problem. telephone set, but due to a software failure. It is in such cases that it is necessary to reflash the phone. In addition to fixing the above problems, the software update will introduce a number of useful changes. For example, increasing the functionality of a gadget, which is achieved thanks to constant updating Android firmware versions and introducing new options and capabilities.

Do not confuse flashing and updating.

How and why are tablets and smartphones reflashed?

Sometimes programs require ROOT access from users. With standard firmware you cannot have administrator rights. For example, serious overclocking of the processor on the device is possible, provided that you have ROOT rights.

Reflashing will rid the device of “garbage” that could have been left by the manufacturer. Instead, the really necessary and necessary programs. Reflashing will give faster and stable work devices, which will also please you.

It may take a couple of months from the time the device is manufactured at the factory until it reaches the user’s hands. During this time, the firmware could have seriously changed and provided more advanced capabilities for the device. This article describes the independent possibility of flashing your phone's firmware. Samsung Galaxy on Android. There are several methods to reflash Android via a computer.

Why do you need official firmware?

Do not forget that the firmware itself must be official. Amateur options eliminate the shortcomings of the OS, but can bring many other “bugs”. Detailed information on the Android firmware is required before implementation.

Today there are many methods for flashing smartphones and tablets on Android based. The most understandable and common options will be described below.

How to properly reflash Android using a PC and the Odin program?

First method

This is done directly from the phone via Android system. For example, version 4.0 is installed on your smartphone. If in this version you open the section “Settings - Phone information - Software update”, then you can configure automatic firmware For this phone. To do this, you need to check the “Auto-update” box. It is also recommended to activate the “Wi-FI Only” option. In this case, availability new version carried out only if available wireless network for phone. It will be spent differently mobile traffic, which will cause considerable expenses. The scan is started manually after clicking the “Update” button.

You can reflash Android via a computer only if the battery is 100% charged. But similar method Samsung Galaxy firmware update is not very convenient and can be interrupted in the middle of the process. It is recommended to perform this task using a special program that is installed on the computer when the phone is connected to it via a USB cable.

Special software

This can be done using the program Samsung Kies or the popular Odin. In the case of the latter, it is possible to use both official Samsung firmware and firmware from other developers. They are often more convenient and give you more options for your phone, but they void the factory warranty. For this reason, following any instructions regarding whether Android is unofficial is only permissible after the warranty period has expired.

Official Samsung firmware Galaxy can be considered as an example of updating using the Samsung Kies program. It is created similarly to iTunes from Apple and can completely synchronize a computer with a smartphone - move files, music, contacts. Before starting the firmware update, it is recommended to create a backup copy to avoid data loss.

Task order

First, install the program itself. During this, drivers for devices from the specified company will be downloaded to the computer and phone. After starting the program, the phone is connected to the computer via the USB port, then we wait for it to be detected. After opening a window with all the phone data, you need to select “Firmware update”; if available, this will be reported in the window that opens. After clicking “Update” you must agree to the rules and confirm the actions. You should wait until the action ends, how to reflash Android Samsung. There is no need to touch the smartphone at this time and disconnect the cable connecting it to the computer. It may happen that your antivirus or firewall will issue a message that requires permission in order for Kies to perform its functions. You should also disable the antivirus on your smartphone, as it simply will not allow the system to update. After this, you need to confirm the end of the update.

Samsung firmware using Odin

To flash your phone using this application, install on PC special driver, which came with the phone, or download this driver from the website of the Android device manufacturer itself.

Then the firmware itself is downloaded. It’s easy to find it on forums or on
file sharing sites. The file must have an OPS extension.

Then you need to simultaneously press three buttons on your smartphone. These are “minus volume”, “power” and “homer”. The message “downloading” will appear on the device screen, which signals a flashing.

Connecting your smartphone to your PC

To do this, connect the smartphone and computer using a USB adapter. Then the Odin program starts. Recommended for downloading latest version programs, especially when installing new firmware. In the menu you need to find the inscription “Select Ops”, click on “OPS”, which is located under it. Next, indicate the path to the firmware file.

Then you need to click on “Start” and wait for the flashing to finish; this will all take no more than five minutes. After completion, the message “Pass” will appear in the first window, which indicates the successful flashing of the smartphone.

This is a “gray” way to reflash an Android smartphone. To begin with, the phone is switched to the “Downloading” download mode. This requires simultaneously pressing the following buttons: “power”, “home” and “volume minus” (or “volume plus” on some models). If everything is done correctly, the display will show Android logo and an inscription about boot mode. Then the Odin Multidownloader program is downloaded and installed. It can be found through a search engine or on a specialized website.

This program is professional for use in service centers. If you use it correctly, there will be no damage to your phone. You will also need files for the firmware downloaded from the official website or from the support forum. There are four of these files.
