Detailed instructions for android firmware. How to make your own firmware on Android: detailed instructions. Flashing Android through a computer using the SP Flash Tool as an example

Not many users understand what phone firmware is until they encounter such problems as performance degradation, bugs, frequent freezes, unauthorized shutdown of the device for no apparent reason. Firmware provides a unique opportunity to eliminate factory defects on a newly purchased smartphone. It also helps to modify and modify the software stuffing of the gadget, according to the tastes and needs of a particular user.

As a result, flashing literally gives a new life to the Android gadget, allowing you to eliminate many common problems associated with its long-term operation. Thanks to this procedure, cellular telephone shows high performance for several more years.

Update and new life of Android system

Phone firmware: what is it?

In a nutshell, for an uninitiated user, firmware is a complete update of the non-volatile memory of a digital device, that is, something like a replacement for firmware.

The operating system under which the phone runs is the holy of holies of any digital device model. From optimal setting system depends on the full performance and expansion of all available functionality.

Firmware means a complete set of all software settings, this is the process of uploading a new software shell to the device, and a file image that includes the entire “flash” memory of the phone.

Firmware adds security to a digital device

Customize a smartphone, that is, update the operating system, expand functionality and add everything modern devices You can do it yourself with a computer. Firmware carried out at home in accordance with all the rules does not cause further malfunctions in the operation of mobile devices.

Important! Within the same line, you can improve some options in the phone, for example, improve image brightness, increase battery life, . But do not be naive to expect that the old device is transformed into a new generation phone.

Why do you need to flash a digital phone?

Partial or complete software updates are usually carried out for three reasons:

The need for Russification of digital devices. These are models imported from abroad that have an interface in a foreign language and are completely devoid of support for the Russian language.
In case of replacing outdated software with more new version. Digital devices are flashed in order to "enrich" the phone with improved trendy features that were not originally provided by manufacturers.
Due to serious damage in the software shell of the smartphone. This can be either a partial inoperability of individual built-in functions, or a complete failure to start the system.

What is needed for self-flashing the phone?

A user who does not have initial skills and knowledge about the principles of operation of the software, and is little versed in computer programs- it’s not worth the risk, but it’s better to entrust the digital gadget to a specialist.

Flashing is only a small part of what is loaded into the memory of a digital device. If you decide to make the firmware with your own hands, then the first step is to familiarize yourself with the components of this process, and familiarize yourself with the terminology.

The main parts of the firmware consist of two elements:

Fullflash (fullflash) is a complex of all software utilities built into the device, that is, a complete image of memory.
Monsterpack (monsterpack) is a software "fill" from the manufacturer. It is a complete set of all programs and consists of three parts: device software image (firmware), FlexMemory (flex) and EEPROM.

These components listed above must be replaced, either individually or in combination. However, for the uninitiated user, the question becomes: where to get the manufacturer's source codes for a complete update of these parts?

It is practically impossible for an ordinary inhabitant of the Internet to find original codes, and self-made ones will easily turn a smartphone into a “brick”. Based on this, it is recommended to limit yourself to replacing only the firmware, or to entrust the digital device to specialists.

Tools to update Android on your gadget

What tools will be needed:

The smartphone itself.
Computer or laptop.
Special USB cable.
Required drivers.
Appropriate firmware version.

Saving the installed firmware version

Before installing the firmware mobile phone, try to save all data (settings and programs) using a special backup application to a memory card or computer. A backup copy of the existing version may be needed if, not a fact of course, but something goes wrong or the new firmware degrades the device's performance.

Launch ClockworkMod Recovery and go to the "Keep current ROM" tab.
Click "OK", thereby starting the creation of a data backup.

Backup button for backing up files

Restoring a saved version is started by opening the same option CWM Recovery, further launching the "Restore" function.

Preparing the smartphone for the firmware procedure

Firmware for different models of smartphones will require "uploading" the appropriate software. Therefore, it is recommended to study all the subtleties of the firmware for your phone model. There are many special resources on the Internet, for example, 4pda, where you can find suitable software, a program for installing firmware, drivers, as well as instructions for the process itself.

Important! Before starting the firmware, it is worth disabling the anti-virus program on the digital device, otherwise it will not allow the launch of new software.

The preparatory process takes about half an hour, perform the following steps:

Download and install the "MobileuncleMTC Tools" application using Google Play.

Step by step to install the application

Install the program with administrator rights.
Download the "CWM - recovery" file suitable for flashing a specific smartphone model.

Built-in options submenu in ClockworkMod Recovery

Drop the ZIP folder with the downloaded files (firmware, recovery) on the smartphone's CD-card.
Open the main menu of the installed Mobileuncle utility, find the Recovery.
Start the update by simply clicking "ok".

The main window of the program, and the option "replace recovery via update from sdcard

The procedure for self-firmware android through a computer

After carrying out the preparatory steps, the android device is completely ready for the most important procedure. The following recommendations will acquaint users with how to properly flash an android on their own through a computer and avoid mistakes. Recommended course of action:

Check the phone's charge, it should correspond to at least 50%. Flashing smartphones from different manufacturers differs in the time spent. So the procedure for flashing the Chinese model will take much less time, unlike European counterparts.
Connect smartphone via USB port to the computer, wait for it to be detected.
Open ClockworkMod Recovery.
In the menu, select and click on "Wipe". This option will reset all data from the device.
Then select "Wipe cache partition", click.

The main Recovery menu and the "wipe cash partition" option, which is responsible for erasing all temporary accumulated files

After agreeing and confirming, click on the "Install form scard" item, after which the "Choose Zip from internals sdcard" option will open. Click on the previously downloaded flashing file image.
Wait until the installation process is fully loaded and reboot the device. During the entire process, it is strongly recommended not to disconnect the connecting USB cable.

Alternatively, after reinstalling the software, your smartphone will not want to turn on the first time. Don't be nervous, try restarting it one more time. If no changes appear, it is recommended to reflash again, or restore an old saved version.

For those who are better off seeing once than hearing a hundred times, it is recommended to watch a video with detailed instructions on Android firmware:

Smartphone firmware provides users with opportunities that are difficult to overestimate. This is an effective increase in the performance of almost all the functionality of your favorite gadget. However, deciding to do this procedure yourself, it is worth considering that the process is quite risky.

Today, you can update or change the firmware of your device without contacting specialized centers. You are basically just wasting your money and time. How to reflash the phone yourself? We will give specific answers to this question in our article.

Firmware Features

Now we will list a few important items that are necessary for flashing your cell phone.

First, make sure that the battery is charged at 50 percent or more (the best option is a full charge), as the flashing process can be quite lengthy.
If you are afraid of losing important data contained on your cell phone, then back up your files and the information you need.
For flashing, you will need a standard USB cable that comes with the phone.
The PC must have the appropriate software to flash your phone. You can find all drivers on the official websites of manufacturers or in numerous alternative sources. There are pirated and licensed versions of the software, which differ significantly in their functionality. It should be noted that official ones are not always better than pirated ones. After successful installation, you need to restart your smartphone.
Your device must have a clean ESN, that is, not be in the database of stolen or lost.
Next, you need to find out (for some models) MEID and ESN, where the first consists of 18 (starting with 2) or 15 digits, and the last of 8.
Today there are 3 types of firmware: from a ZIP archive, a TAR archive, or a three-file one. Below we will go into more detail about each of them.

Are you still thinking how to reflash your phone? Believe me, it's not difficult at all. A little later you will see for yourself.

Firmware: "Android" from the ZIP archive

This is one of the best methods used by many users. So, how to reflash a phone ("Android") from a ZIP archive? First, you need to set root rights. It is worth noting that not all devices have this feature. Plus, having achieved root rights, you will immediately lose the warranty on the device. Secondly, you need to make a backup, that is, a backup copy of important files. What is needed for this? You can, for example, install a special system recovery program, an excellent example of which is ClockWorkMod. It is designed to flash phones on the Android OS, and in case of any failures, it allows you to return to the source code. To make a backup using the above program, you must take the following steps:

Launch ClockWorkModRecovery.
Select "Backup & restore".
Further "backup".
Confirm by pressing the "YES" button.
Reboot your device by clicking "Reboot system now".

After completing these steps, a backup should appear on your MicroSD in the "clockworkmod / backup" folder. At the end of all the above operations, you can proceed directly to the flashing. So, how to reflash a phone ("Android") from a ZIP archive?

After downloading the ROM file, write it to the memory card. The firmware name can contain Latin letters and numbers, and the file itself must be in a ZIP archive.
Disconnect your phone from PC and charger.
Next, turn off the mobile phone and start the recovery mode.
In the menu we find the item “Wipe”, which erases the current information of the system.
After that, you need to return to the root of the menu and select the item "Flash Zip from SD-Card" or "Install zip from sdcard".
We find the ROM firmware located in the ZIP archive.
We confirm the firmware and follow the instructions on the screen.
If everything went well and without errors, reboot the phone by selecting "Reboot system now".

We are done with the first method. Now let's move on to the 3-file firmware.

How to flash Android with three-file firmware

For this method, we will need the Mobile Odin Pro application, which is another program for android firmware. If you decide to flash it in this way, then you can not get root rights. How to flash a phone with 3-file firmware? Let's move on to the algorithm of actions:

First you need to write files to a smartphone or tablet (3 files that have the words CSC, CODE, Modem in their names). It is desirable to throw all 3 files in one folder.
In the Mobile Odin Pro app, select "Open file".
Next, a window should appear where you need to select a file that has the word "CODE" in its name. Click "OK".
Then select the "Modem" item and press the "OK" button.
We check that all sections have data.
At the end of the check, click "Flash Firmware".
We are waiting for the firmware process to end, which can last over 15 minutes.

Finally, we move on to the last firmware method.

How to flash Android from a TAR archive

Not the most popular method, since there are very few firmwares that are packaged in a .TAR archive. Generally speaking, most of the process is the same as the previous method. How to flash a phone from a tar archive?

In Mobile Odin Pro select "Open file".
In the window, find and select the downloaded firmware, which has the format .tar or .tar.md5, which was previously written to the “Firmware” folder. Click "OK".
After we check that all sections have the necessary data.
Next, click "Flash Firmware".
We are waiting for the installation to complete and reboot the device.

I would like to say a few words about the firmware of Chinese phones. Such devices are updated in exactly the same way, but there are a number of nuances. Firstly, it is very difficult to find high-quality firmware, and for some gadgets it is completely impossible. Secondly, various fakes (like the iPhone, Galaxy S4 and others) are unreliable, which is why custom firmware can cause irreparable harm to the device. That's all, we hope that our instructions answered your question on how to reflash a Chinese phone and original devices in order to update an already boring system. However, remember that flashing Android is an operation at your own peril and risk, which may not have very rosy consequences.

How to flash a Samsung phone

In this section, we will describe flashing using the MultiLoader application. After downloading it, you need to run and select the "BRCM2133" item. Then follow these instructions:

We pass to the "Download" mode by holding down the off (lock) and volume keys. If the message “Download” appears on the screen, it means that everything went well.
We connect the phone to the PC using a USB cable. After detecting the device, press the "Download" button and wait a couple of minutes.
Disconnect USB and reboot smartphone. If the mobile phone starts in English, then we do a simple “Preconfiguration” by typing “*#6984125*#” → “Pre-configuration”, after which we enter the password “*#73561*#”. Select your country of residence and reboot. Next, in the window we drive in “*2767*3855#”, which will help reset the settings.
Everything is ready. The system has been updated. We think you understand how to reflash a Samsung phone.

Nokia Firmware

New models support the over-the-air flashing function, that is, without connecting to a PC. All you need is high speed internet. So, how to reflash a Nokia phone? First of all, go to the "Settings" => "Phone" => "Manage your phone" => "Device update" section. You will be presented with all the important information about the phone model and firmware version. Select "Functions" => "Check for Updates". If newer versions of the software are found, you will be notified and offered to upgrade the old firmware. Everything is done automatically.

If you wish to update the system via a computer by connecting a USB cable, simply download the Nokia Software Updater application and run it. Then follow the instructions that will appear on the screen of your smartphone.

How to flash an HTC phone

First you need to download the firmware itself. In addition, it is important to get root rights and make a backup according to the method described by us earlier. You can also create a backup using the Titanium Backup application. Let's get down to the process:

First we do a full "wipe". How to do this, we have already told.
Next, select "install zip from sd-card" in recovery.
After you need to enable or disable signature verification "toggle verification mode".
We find our firmware and run it. We are waiting for the update to complete and reboot. At the end, "Installation completed" should be displayed.

As you can see, the firmware of phones of this model largely coincides with the method of flashing from a ZIP archive that we described earlier.

Sony Xperia Firmware

For the firmware we need Flash tool and USB cable. Let's start the process. So, how to flash a Sony Xperia phone?

First, we download the firmware we need, which will have the .ftf format.
We drop this file into the / flashtool / firmwares folder.
After you need to run the FlashTool utility, turn off the phone and wait 30-60 seconds. Next, click on the button in the application where the lightning is drawn, and select "Flashmode".
A little later, you will be given a message that the firmware is ready for installation, and you need to connect the device.
We hold down the key responsible for lowering the volume, after which the Flashtool program identifies your device.
We are waiting for the end of the firmware until the inscription "Flashing finished" appears. We reboot the device and enjoy the updated software.

We turn to the last phone, for which we will tell the firmware process.

Fly Firmware

So, how to reflash a Fly phone? Follow the algorithm:

We connect the phone (turned off) to the PC via a USB cable.
Download, install and run the same FlashTool.
Go to the "Download" section, where we indicate the COM port and speed (we do not recommend setting it above 460800).
Specify the bootloader ("Download Agent").
We load the memory allocation scheme of your smartphone (“Scatter-loading”) and then check the lines with the areas of the device’s flash memory that are subject to programming.
Click "Format FAT", where we select "Manual Fat Format". In "Begin address" and "Format Length" in hexadecimal format, you must specify the starting address (0x0), as well as the size of the smartphone's memory to be cleared. Be careful as it is possible to inadvertently delete the calibration data.
Click "OK", then press the power button of the device.
To start the firmware process, you must click the "Download" button.
After the update is completed, disconnect the phone from the USB cable and reboot it (several times if necessary).

As you can see, everything is quite simple.

Finally

Many users of phones on the Android OS sooner or later wonder about changing the firmware, as the original one becomes obsolete, which affects the overall performance of the phone. Along with this, interruptions in the operation of the system very often occur, which is especially true for Chinese phones. Nevertheless, for various reasons, not everyone wants to go to a service center, preferring to reflash their smartphone themselves. In this article, we have provided many illustrative examples this process. We think you were interested.

But here's how to install them specifically on your smartphone or tablet model, there is very little information, or scattered across the Internet.

This article only applies to installing custom ROMs using ZIP UPDATES, and not in any other way.

Briefly about the main ...

The Android operating system, it will remain the same in Africa, whether you have Samsung, LG, HTC, Sony, Motorola or another manufacturer ... There is a certain set of rules, a sequence of actions that are slightly supplemented depending on the manufacturer, but the process of installing custom firmware similar to all devices. Here are the simple steps:

There are a total of 8 steps (2 are optional, 2 are done once). Of these, in the future you will repeat only 3 - 5 if you suddenly want to change the firmware.

Ready solution!

The site site has prepared separate instructions for installing custom firmware for the following brands and manufacturers:

Installing custom firmware on Nexus
Installing custom firmware on Samsung
Installing custom firmware on HTC

Where can I find custom firmware for your Android?

There are different ones from different manufacturers, only you yourself know which one will be best for you, so try and experiment!

firmware Linage OS(former CyanogenMod)
firmware MIUI
firmware OMNIROM
Firmware Paranoid Android - official, amateur
firmware AOKP
firmware Slim ROM
firmware P.A.C.MAN
firmware Carbon ROM
firmware Resurrection Remix
firmware PRO-BAM (AOSB)

Download GAPPS

Do not rush to jump over this heading! You are probably used to using Google services - Google Play App Store, YouTube, Gmail, Maps, etc. They are not in the original custom firmware! Therefore, you will need a ZIP update from GAPPS. It is necessary to download the GAPPS version from the version of Android on which the custom firmware is based (if the firmware is from Android 4.4, then GAPPS should be for Android 4.4).

Making a backup

This item is optional, but what if you want to go back or something goes wrong? So do it.

Unlock Bootloader

You are a happy owner of Sony, HTC, Huawei, Nexus, then you will have an additional procedure on the way to installing custom firmware - unlocking Bootloader.

Unlock Bootloader Sony
Unlock Bootloader HTC
Unlock Bootloader Huawei
Unlock Bootloader Nexus

This procedure is performed once and can be skipped in the future.

Find and download custom Recovery (or Kernel with Recovery)

You are moving by leaps and bounds to install your first custom firmware! Moving on… You also need to download a custom Recovery, why you ask?

There are several reasons:

In some devices, it is simply not available (Recovery), and you need to install custom firmware and GAPPS from under it
It will not be possible to install custom firmware from under the original Recovery (if any), due to the fact that there is no manufacturer's signature there, and custom Recovery disables the signature and allows the installation of various ZIP updates, including custom firmware.

In some cases, Recovery is built into the Android kernel (Sony, sometimes Samsung) so you need to look for a kernel with CWM or TWRP Recovery instead of just looking for Recovery.

The 4pda website describes in detail where to find it and how to install it -. Recovery can also be searched on Google and XDA and w3bsit3-dns.com resources.

If you do not delete Recovery in the future, then you do not need to install it anymore.

Installing Custom Firmware

So you have done the following required steps:

Download custom firmware
Download GAPPS
Bootloader unlocked
Download and install Recovery

Now move the ZIP archives - Custom firmware and GAPPS to a memory card (if there is a slot) or internal memory Android smartphone or tablet. data reset or wipe. If the reset is not performed, then you will get an eternal download of Android (bootloop).

First boot Android

After installing the Custom firmware and resetting the data, restart Android, as a rule, the first boot is very long and lasts from 3 minutes to 15 minutes. This is due to the first hardware setup and before installing the system. The most important thing is not to be nervous and not to reboot the device during this period of time.

This completes the installation process of Custom Firmware! It may seem to someone that it will take a lot of time for everything about everything, but in fact, if you fully understand everything that you are doing, then the process lasts no more than 15 minutes (if you do not take into account downloading the necessary and waiting for the first download).

Hello! Today we will consider the simplest and most convenient methods for flashing your smartphone (or tablet).

The article is divided into the following sections:

Why do you need a flashing?

Everything is clear here: either you have problems with the device, or you want something new, but the developers have stopped introducing new versions of the OS.

What are the ways of firmware?

There are two of them, but each in turn is divided into several more.

Firmware via phone.
Firmware using a computer.

Now we will consider several methods of firmware using a PC.

Necessary preparation before the flashing process

All this must be done so that there are no disruptions in the installation of a new OS.

Fully charge the device and your computer;
Make a backup copy of the old OS;
Check if the USB cable is working.

Making a backup

The example shows Android 5.0, but all the steps described below are almost the same in any of the versions. So please read this manual carefully.

Go to your device settings.

2. Select the "System Information" item and the "Memory" section.3. Now click the "Backup" button.

4. Now everything is simple: make a backup by selecting the items you need to save, as shown in the pictures.

5. All backup copy ready. You can copy it to another device or use it.

Firmware using FASTBOOT

Now that all possible security measures have been taken, you can proceed to the firmware.
First, download Fastboot to your computer. Make the boot folder of the program in the root directory of drive C. For example, C:\fastboot. In this case, it will be easier for you to prescribe the location of the firmware in the future.

The installation file can be downloaded from the link (Android debugging utility).

First unlock bootloader
Bootloader is a program outside the Android system that provides access to the device's kernel. It can be compared to the BIOS on a computer.

By unlocking it, we will get root rights - open access to the system. On devices from different manufacturers, this is done using different software. But there is only one algorithm of work, and it is like this:

You download and install the unlock program according to the manufacturer of the device.
Then connect your smartphone via USB cable in debug mode.
Open the downloaded program, select your device and click "Unlock".

Unlock example
Here is an example of unlocking an HTC device.
1. Download and install HTC Bootloader Unlock.
2. Then connect the device to the computer in debug mode. Everything is quite simple here: go to the “For Developers” settings section and select “USB Debugging”.

3. Now open the downloaded program and confirm debugging (on the android device).

4. It remains just to unlock by pressing the "Unlock" button. In fact, the process can be executed through the command Windows string. This program only automates the unlocking process.

5. To exit HTC Bootloader Unlock, click "Finish" after the botloader unlock process is completed.

Note: there are unlock programs for a smartphone or tablet of any manufacturer. For example:
Nexus - Nexus Root Toolkit
Samsung-Kies
Sony - Sony Bootloader Unlock.
If your device is from another manufacturer, just search the Internet for the appropriate utility.

Firmware process

The first thing to do is connect to the computer in USB debugging mode. How exactly to do this is described a little earlier.
First move the new firmware to C:\fastboot

3. Now put your device into fastboot mode. IN command line enter the commands as shown in the screenshot.

4. In order for the flashing to be successful, you need to format all the directories of your device. Enter these commands in the command line in turn (after each - "Enter"):

fastboot erase boot
fastboot erase userdata
fastboot erase system
fastboot erase recovery
fastboot erase cache

5. And now you can start the firmware. From the folder with the firmware ("fastboot" folder), run the flash-all bat file. This is what it looks like on the command line:

6. After a successful flashing process, you will see a message about it. That's all, the device is flashed. And after rebooting it, you can verify this.

Reflashing using the ODIN MULTI DOWNLOADER program

1. First you need to connect your phone to the computer using a USB cable, in debug mode. After that, be sure to run the Odin Multi Downloader program as an administrator.

2. Then specify the location of the firmware you want to install. Here's what to do: click on the BOOT button and select the firmware file.

Note: if your firmware consists of several files (mostly three), then the path must be specified accordingly:
PDA file - in the "PDA" field;
file Phone - in the field "Phone";
CSC file - in the "CSC" field;

3. Now you need to restart your phone. This can be done using key combinations (volume up + screen lock button + center button). As a result, the computer should recognize the phone, thereby a yellow field with the name of the COM port will appear on the screen.

4. After you click the "Start" button, the system update will begin. During this time, do not disconnect your phone from the computer. During the installation process, the smartphone will reboot several times, but you should not pay attention to this. After a successful firmware (which takes about 10 minutes), the word “PASS” will appear on the computer screen.

After completing all the steps, according to this instruction, you can use any version operating system Android. In addition, it is worth noting that this program suitable for flashing android devices of any manufacturer.

Flashing an LG Android device using the KDZ UPDATER program

If you have a phone or tablet from the manufacturer LG, then it will be easier, and more correct, to flash it using the KDZ Updater program. How exactly to do it?
1. Download KDZ Updater first. Actually, this is an archive that needs to be unpacked into a folder located in the root of the system drive C of your computer.

2. In the same root folder, add the firmware you need. Here is the executable file of the program, the only way the firmware will be visible to the program.

3. Be sure to install the action policy file called msxml.msi
4. Now enable USB debugging mode. How exactly to do this is described above.
5. Put the device into S/W Upgrade mode. Namely:

turn it off;
take out the battery;
hold down the volume down key and plug in the USB cable.
the corresponding inscription will appear - “S / W Upgrade”.

Notes:
if it was not possible to enter the S / W Upgrade mode, then try to do all the above steps without removing the battery;
also try instead of the volume down key, hold down both "sound rockers";
In order for the firmware to become possible, you need to disable the LGE Mobile USB Modem program in the Device Manager.

6. Now it's time to start flashing. Run the executable file of the program KDZ_FW_UPD.exe as administrator from the root folder on drive C.
Note: hover over the program icon and right-click. Select "Run as administrator".

7. Set all options as shown in the screenshot and click "Launch software update".

8. After a while (about 10 minutes), the firmware will be completed. Just restart your device and enjoy the new interface.

Firmware for smartphones and tablets from Lenovo

Why did I bring this topic separately? Because Lenovo devices have their own nuances that create certain difficulties. However, there is a program that compensates them. What exactly? Ease of use and its intuitive interface.

So, let's begin.
1. You need SP Flash Tools firmware. Download it.
2. To continue the firmware, you need to install drivers on the device. As a rule, when connecting, they are not automatically installed. Therefore, you need to do it manually.
download drivers according to your device model;
turn off the device;

select driver.

Enter into the device manager on the computer (the above shows how to do this);
turn off the device;
connect the device via USB cable to the computer;
right-click on the device that appears (unidentified) and select "Install driver from a list or location";
select driver.6. After the flashing is completed, you will be notified of this by the appearance of a bright green ring on the computer screen.

When you turn on the device, the first boot of the system will take quite a long time (5-10 minutes). That's how it should be, don't worry.

Brief summary

As you can see, for android devices of some manufacturers there is a special software, which facilitates the firmware process. So use it first.

However, there are many methods for flashing an android device using a computer. How many utilities are there that make this process easier. But the above methods, in my humble opinion, are among the most convenient and easiest. So read, understand and go!

Today we will tell you how to flash an Android phone through a computer. According to statistics, of all phones sold in the world, devices with the Android system occupy 80%. As a system available to everyone, it is downloaded and installed on a lot of devices, from well-known Samsung to little-known Chinese manufacturers. Due to failures in phone optimization, users are trying to make android firmware using a PC.

Basic firmware rules

Before you start flashing your smartphone, I recommend that you study the basic recommendations:

Try to find out and make sure that there is no specific manual for your device. This may well be if you have a Chinese phone.

To upload files, use only trusted sites.

Do not turn off the device. The battery charge must be full, otherwise you risk causing an error.

When carrying out the firmware, you must use the cable from the kit, that is, the original one.

Of course, you must understand that the whole process will be on your conscience. Incorrect firmware can cause the device to simply not turn on and the warranty, if any, will also end. The most reasonable action with a valid warranty would be to contact the service.

Choosing the right version for installation

In the whole process, the most difficult moment is the search current version, which will be suitable for your device and at the same time will not conflict with the system.

First, determine the firmware that is currently on your phone:

Go to settings.
Go to point "About Device" and find the firmware version or "build number".

Choose ZIP files to download. Do not ignore the installation guide for users.

Consider the general order for all Android devices, despite the fact that utilities can be used differently, given the device model.

Device preparation

For a smooth and trouble-free installation, you must be rooted. This can be done using the KingoRoot program. Start the program, connect USB cable and as soon as the synchronization is finished, click the button ROOT.

After restarting the device, you will be able to perform the necessary conversions.

I advise everyone to create a backup copy if the flashing suddenly fails. Use the Titanium Backup program. It will allow you to create a software backup and a copy of all system information.

Next download CWM Recovery and place it on the memory card. The file should be located exactly in the root folder, and be named recovery.img. It will be installed via RomManager .

How to flash an Android phone through the menu

After you have placed the file in the root part of the memory card, you will need to turn off the device, and then, simultaneously hold down the button on the phone power and adjust the volume to the "down" position. In a similar way, you will go to the recovery menu.

Before installing a new system, you will need to uninstall the old one. Moving through the Recovery menu occurs through the power button and volume change.

Skip to section Wipe and open it.

Activate the formatting process - Wipe all data/factory reset».

Clear the machine's cache.

Delete the cache from the folder Dalvik, which you can find in the section "Advanced".

Make the transition to the main menu and refer to the section Mounts. Click to "format /system".

The data is deleted, the old system too, which means you can install another version. Through the main menu go to "Install zip from sdcard".

Click on "Choose zip from internal sdcard" and you will see a list of memory cards. Click on the firmware file.

Confirm the process.

The firmware will take you quite a bit of time. The first boot should not cause you to panic, as it will take a long time to complete. All that is required of you in the future is to set the date, language, etc.

Use your smartphone often to identify possible gaps in the firmware. If you have not noticed any problems and the device works fine, then the firmware was successful.
