Download sp flash tool version 5.1640 00.000. How to flash a phone or smartphone using the SP Flash Tool

SP Flash Tool is a smart and handy tool for flashing devices based on MediaTek chipsets. If you decide to flash an Android smartphone or tablet with such a processor "under the hood", then you first need to take care of the ability to backup the device's ROM if something goes wrong. In addition to the usual reason (precautions), there is another reason here: not every firmware you choose may be suitable specifically for your device. Therefore, it is worth making sure that the requirements for display characteristics, memory size and other regulated new firmware parameters are fully met. AT otherwise software, and with it the device, may be partially or completely inoperative. Practice shows that if the parameters match, the firmware of an Android smartphone using the SP Flash Tool runs smoothly, but we decided to still give instructions for creating backup.

Creating a full backup copy of the Flash-memory of the smartphone

To create a backup copy of the Flash memory of an Android smartphone, you must have the utility itself installed and.

1. Run the USB flash drive, then in the "Download" tab, download the scatter file (if necessary, you can borrow it from an Android device with a similar processor). Do not be alarmed if you do not see any firmware files in the folder with the scatter file - this is normal. Leave a tick only on the first line (PRELOADER), uncheck the rest.

2. Determine how much information and from where to read. After that, go to the "Memory Test" tab. Here, too, there is only one check mark on " RAM Test", the rest must be removed.

Proceed next in the following way:
2.1. Press the Start button;

2.2. Through the USB port, connect the switched off Android device to the PC;

2.3. The memory test that occurs after connection will show the information you need on EMMC blocks (do not pay attention to blocks with zero volume, only those with a size will be needed;

3. Copy the received information into a notepad, then go to the "ReadBack" tab and click "Add".

3.1. Double click on the line that appears;

3.2. Specify the file name (ROM_0 by default), and specify the location where the memory block will be saved;

3.3. Based on the data obtained earlier, fill in the three parameters in the window that appears.

You got the names of your regions, the size is known, and starting address in each of them will be 0x0.
Example:
Region: EMMC_USER Start Address: 0x0 Length: 0x3ab400000
After filling in the parameters, it remains to click the "OK" button.

note : the example device has 4 regions, but this does not mean that there are the same number of regions on other gadgets. Flash memory can have 3, 2 or even one region ("USER"). In the latter case, you won't have to select a region - this option will be absent in the menu for entering block reading parameters. As a rule, this situation happens when working with Android devices based on chipsets of early release years.

3.4. Press the "ReadBack" button, reconnect to the USB port of the turned off gadget - reading will start;

3.5. After the reading of the block is completed, repeat the manipulations described in paragraph 3 with all other regions.

Thus you will receive full copy flash memory of your Android device.

If you decide to use the SP Flash utility, the easiest way is to take it for firmware (modified recovery specifically for your device) and download to your home computer the corresponding MTK gadget processor. All old drivers related to Android devices will need to be pre-delete. You will also need to download the version for Windows or Linux. And do not forget at the same time that the SP Flash Tool for MTK devices can be compatible with 32 or 64-bit versions of the PC OS - it is important to choose the right one, corresponding to the system installed on your home computer.

Of the hardware you will need:
1. home computer Windows/Linux;
2. A working USB cable for switching with an Android device;
3. Android smartphone or tablet computer.

SP Flash Tool can flash devices based on MT6575, MT6577, MT6577T, MT6595, MT6592, MT6582, MT6572, MT6589, MT6589T chipsets.

Driver installation

Let's assume that you already have a driver archive on your PC - for example MTK_drivers.rar. The first step is to turn off your smartphone or tablet and launch "Device Manager" from the control panel. Connect your Android device to your computer with a USB cable and wait for the Manager to update and detect unknown device. Next, you need to act very quickly: until the smartphone has switched to charging mode, right-click on an unidentified device and in the window that opens, select " Update Driver".

Driver installation is done manually. In the next window, select "Install driver from a specified location", then specify the path to the driver archive (it must be unpacked beforehand) and install the required one. You can now disconnect your Android device from your PC, but it's still too early to turn it back on. But you can go directly to the firmware process itself.

Instructions for flashing smartphones based on MTK

Here we present the complete step by step instructions, following which you can independently flash an Android smartphone or tablet based on MediaTek processors.

1. Download the SP Flash Tool and extract the archive to your computer;
2. If you have a device with an MT6575 or MT6577 processor based on the AGOLD project, download the SP_MDT program on your computer with the ability to select components in uboot and unpack it;
3. Download and install USB VCOM drivers;
4. Unpack the archive with factory firmware for your Android device (the directory name for the unpacked folder with factory firmware files should not include Cyrillic characters);
5. Turn off your smartphone or tablet, the USB cable must not be connected to the computer;
6. Remove the battery, then insert it back;
7. If the drivers have not been installed yet, connect the machine to the PC with a USB cable. The operating system will then find a new device, and you must specify the folder with USB driver VCOM for your OS version. Install the drivers and unplug the cord from the PC.
8. Run SP Flash Tool;

9. Click on the Scatter-loading button and select the file MTXXXX_Android_scatter_emmc.txt in the folder with the firmware (in MTXXXX, replace the X letters with the numbers corresponding to the processor of your device - the scatter file is different for each of them).

ATTENTION! For devices based on MT6575 and MT6577 processors, uncheck the Preloader and dsp_bl items, for all other devices with MediaTek chipsets, uncheck the Preloader item only;

10. Click the Download button;

11. Connect the switched off smartphone or tablet to the computer via a USB cable. As soon as a new device is detected, its firmware should begin. If this does not happen, disconnect the device from the PC, remove and reinsert its battery, and reconnect it to the computer. During the firmware process, provided correctly installed drivers mtk usb port (MediaTek PreLoader USB VCOM Port) should be observed in device manager. If an error occurs, the gadget will no longer be displayed. When the firmware is completed, it also disappears from the device manager.

Firmware successfully completed? It remains only to disconnect the Android device from the computer and turn it on.

SP Flash Tool is a program for flashing Android devices based on Mediatek (MTK) chips. Unfortunately, sometimes the quality of Chinese firmware leaves much to be desired, or even the manufacturer stops updating the phone. Some functions stop working, the smartphone starts to discharge quickly and there is a desire to buy a new one. Self-flashing with the help of popular program SP Flash Tool and computer.

Capabilities

Note! During the firmware of the device, unforeseen situations may occur. The user performs all actions at his own discretion. Loading data using third party program may lead to errors. You should first study the precautionary rules in specialized forums, detailed instructions and choose working version firmware of your smartphone. This is especially true for custom (created by ordinary users based on official) software. The manufacturer refuses warranty service upon detection of "unofficial" interference with the operation of the device.

The SP Flash Tool has the following features:

firmware / flashing with the original version of Android. Manufacturers often forget about their creations, even those released not so long ago. The version of Android with new bells and whistles may not come to the phone. But if its characteristics allow it to be installed, then it can be done using a computer and the Flash Tool. There are also such cases: the manufacturer himself adds his own innovations to the usual firmware. You can put a "clean" version if they are not to your liking. Moreover, they work faster. Flashing saves from system brakes, removing excess and accumulated debris.
flashing with custom (unofficial) software. Special third-party software improves performance, appearance and adds previously unavailable features.
obtaining Root-rights (superuser). Opens previously inaccessible to a simple user opportunities. The manufacturer deliberately underestimates the characteristics of the phone (for example, so that the volume level is invested in the permitted indicators of special EU commissions) - this can be corrected.
installation of third-party Recovery (Recovery). Allows you to backup or restore from it, install custom firmware, OS updates and fixes, format a memory card, etc.

Before flashing, you must fully charge the phone, otherwise it will greatly discharge the battery. And if it is not enough for the whole process, then this will lead to errors or complete breakdown.

Pros and cons

Main advantages:

is completely free and available to everyone (many similar programs for other platforms are not available for ordinary users);
works immediately without installation on a PC;
easy to handle;
support for a wide range of Android devices;
protection against "serious" user errors.

Main disadvantages:

lack of a Russian-language version;
lack of preparation and incorrect actions can lead to errors or even to a complete breakdown of the device.

Download

SP Flash Tool can be downloaded for free from our website. This program will help "prolong" the life of your favorite gadget. In case of the slightest uncertainty, it is better to consult the appropriate forum.

Download Sp Flash Tool you can use the link below for free

MTK hardware platform as the basis for building modern smartphones, tablet computers and other devices has become very widespread. Along with a variety of devices, the ability to choose variations of the Android OS has come into the life of users - the number of available official and custom firmware for popular MTK devices can reach several dozen! To manipulate the memory partitions of Mediatek devices, the SP Flash Tool is most often used - a powerful and functional tool.

Despite the wide variety of MTK devices, the process of installing software through the SP FlashTool application is generally the same and is carried out in several steps. Let's consider them in detail.

All actions for flashing devices using SP FlashTool, including the implementation of the instructions below, the user performs at his own peril and risk! The site administration and the author of the article are not responsible for a possible malfunction of the device!

Preparing the device and PC

In order for the procedure for writing image files to the device memory sections to go smoothly, you need to prepare accordingly by carrying out certain manipulations, both with an Android device and with a PC or laptop.

1. Download everything you need - firmware, drivers and the application itself. We unpack all the archives into a separate folder, ideally located in the root of drive C.

2. It is desirable that the folder names for the location of the application and firmware files do not contain Russian letters and spaces. The name can be anything, but folders should be named consciously so as not to get confused later, especially if the user likes to experiment with different types of software loaded into the device.

3. Install the driver. This point of preparation, or rather its correct implementation, largely determines the smooth flow of the entire process. How to install the driver for MTK solutions is described in detail in the article at the link below: Installing drivers for Android firmware

4. We make a backup of the system. Regardless of the outcome of the firmware procedure, the user in almost all cases will have to restore their own information, and in the event that something goes wrong, the data that was not saved in the backup will be irretrievably lost. Therefore, it is highly advisable to follow the steps of one of the ways to create a backup from the article:How to backup an Android device before flashing

5. We provide uninterrupted power supply for the PC. Ideally, the computer that will be used for manipulations through SP FlashTool should be fully functional and equipped with an uninterruptible power supply.

Firmware installation

Using the SP FlashTool application, you can perform almost all possible operations with the device's memory sections. Installing firmware is the main function and for its implementation the program provides several modes of operation.

Method 1: Download Only

Let us consider in detail the procedure for downloading software to an Android device using one of the most common and frequently used firmware modes via SP FlashTool - " Download Only».

1. Run SP FlashTool. The program does not require installation, so to run it, simply double-click on the file flash_tool.exe located in the application folder.

2. When the program is launched for the first time, an error message box appears. This point should not worry the user. After the path for the location of the necessary files is indicated to the program, the error will no longer appear. Press the button " OK».

3. In the main window of the program after launch, the operating mode is initially selected - “ Download Only". It should immediately be noted that this decision is used in most situations and is the main one for almost all flashing procedures. Differences in operation when using the other two modes will be described below. AT general case leave " Download Only" without changes.

4. Let's move on to adding image files to the program for their further recording into the memory sections of the device. For some process automation, SP FlashTool uses special file called Scatter. This file is essentially a list of all sections of the device's flash memory, as well as the addresses of the initial and final memory blocks of the Android device for recording partitions. To add a scatter file to the application, press the button " choose”, located to the right of the field “”.

5. After clicking on the button for selecting a scatter file, the Explorer window opens, in which you need to specify the path to the required data. The scatter file is located in the folder with the unpacked firmware and has the name MT xxxx _Android_scatter_ yyyyy.txt where xxxx– the processor model number of the device for which the data being downloaded to the machine is intended, and – yyyyy, the type of memory used in the device. Select the scatter and press the button " Open».

Attention! Loading an incorrect scatter file into the SP Flash Tool and further writing images using incorrect addressing of memory sections can damage the device!

6. It is important to note that the SP FlashTool application provides a check of hash sums, designed to protect the Android device from writing incorrect or damaged files. When adding a scatter file to the program, the image files are checked, the list of which is contained in the downloaded scatter file. This procedure can be canceled during the verification process or disabled in the settings, but it is strongly not recommended to do this!

7. After downloading the scatter file, in automatic mode added firmware components. This is evidenced by the completed fields " Name», « Begin Address», « end address», « location". The lines under the headings contain, respectively, the name of each section, the start and end addresses of memory blocks for writing data, as well as the path where the image files are located on the PC disk.

8. To the left of the names of the memory sections, there are checkboxes that allow you to exclude or add certain image files that will be written to the device.

In general, it is strongly recommended to uncheck the box next to the item with the section " PRELOADER”, this avoids a lot of problems, especially when using custom firmware or files obtained from dubious resources, as well as the absence of a full system backup created using MTK Droid Tools.

9. Check the program settings. Press the menu " Options"and in the opened window go to the section" Download". Check the boxes " USB Checksum" and " Storage Checksum"- this will allow you to check the checksums of files before writing to the device, which means to avoid flashing corrupted images.

10. After completing the above steps, we proceed directly to the procedure for writing image files to the corresponding sections of the device's memory. We check that the device is disconnected from the computer, turn off the Android device completely, remove and insert the battery back if it is removable. To put SP FlashTool into standby mode for connecting the device for firmware, press the button " Download”, indicated by a green arrow pointing down.

11. In the process of waiting for the connection of the device, the program does not allow you to perform any actions. Only the button is available stop” to abort the procedure. We connect the switched off device to the USB port.

12. After connecting the device to the PC and detecting it in the system, the process of flashing the device will begin, accompanied by the completion of the progress bar located at the bottom of the window.

During the procedure, the indicator changes its color depending on the actions performed by the program. For a complete understanding of the processes occurring during the firmware, consider the decoding of the indicator colors:

13. After the program has completed all the manipulations, the window " Download OK”, confirming the successful completion of the process. Disconnect the device from the PC and start it by long pressing the " Food". Usually, the first launch of Android after the firmware lasts quite a long time, you should be patient.

Method 2: Firmware Upgrade

The procedure for working with MTK devices under Android control in the mode " Firmware Upgrade»generally similar to the above method « Download Only” and requires the user to perform similar actions.

The difference between the modes is the impossibility of selecting individual images for recording in the option " Firmware Upgrade". In other words, in this option, the device's memory will be overwritten in full accordance with the list of partitions contained in the scatter file.

In most cases, this mode is used to update official firmware the whole working device, if the user requires a new version of the software, and other methods of updating do not work or are not applicable. It can also be used when restoring devices after a system crash and in some other cases.

Attention! Using the " Firmware Upgrade” assumes a complete formatting of the device’s memory, therefore, all user data will be destroyed in the process!

The firmware process in the " Firmware Upgrade» after pressing the button « Download» in SP FlashTool and connecting the device to a PC consists of the following steps:

Create a backup copy of the NVRAM partition;
Full formatting of the device memory;
Write device memory partition table (PMT);
Restoring an NVRAM partition from a backup;
Write all partitions whose image files are contained in the firmware.

User actions for flashing in the " Firmware Upgrade”, repeat the previous method, with the exception of certain points.

1. Select the scatter file (1), select the SP FlashTool operating mode in the drop-down list (2), press the button " Download» (3), then connect the turned off device to the USB port.

2. Upon completion of the procedure, the window “ Download OK».

Method 3: Format All + Download

Mode " Format All+Download» in SP FlashTool is designed to perform firmware when restoring devices, and is also used in situations where other methods described above are not applicable or do not work.

Situations in which it applies Format All+Download", are diverse. As an example, we can consider the case when modified software was installed in the device and / or the device's memory was re-partitioned to a solution other than the factory one, and then a transition to the original software from the manufacturer was required. In this case, attempts to write original files fail and SP FlashTool will offer to use the emergency mode in the corresponding message box.

There are only three stages of firmware execution in this mode:

Full formatting of the device's memory;
PMT partition table entry;
Write all sections of the device's memory.

Attention! When manipulating in the " Format All+Download"The NVRAM partition is erased, which leads to the deletion of network parameters, in particular, IMEI. This will make it impossible to make calls and connect to WiFi networks after following the instructions below! Restoring an NVRAM partition in the absence of a backup is a rather time-consuming procedure, although it is possible in most cases!

The steps required to carry out the procedure for formatting and writing partitions in the " Format All+Download» are similar to those in the methods described above for the modes « Download" and " Firmware Upgrade».

1. Select the scatter file, define the mode, press the button « Download».

2. We connect the device to the USB port of the PC and wait for the end of the process.

Installing custom recovery via SP Flash Tool

To date, the so-called custom firmware, i.e. solutions created not by the manufacturer of a particular device, but by third-party developers or ordinary users. Without delving into the advantages and disadvantages of this method to change and expand the functionality of an Android device, it is worth noting that in order to install custom, in most cases, a modified recovery environment is required in the device - or CWM Recovery. In almost all MTK devices, this system component can be installed using SP FlashTool.

1. Run Flash Tool, add a scatter file, select " Download Only».

2. Using the checkbox at the very top of the list of partitions, uncheck all image files. Check the box next to the " RECOVERY».

3. Next, you need to specify the path to the custom recovery image file to the program. To do this, double-click on the path specified in the section " location”, and in the Explorer window that opens, we find the necessary file *.img. Press the button " Open».

4. The result of the above manipulations should be something similar to the screenshot below. Only the section " RECOVERY" in field " location"The path and the image file of the recovery are indicated. Press the button " Download».

5. We connect the switched off device to the PC and observe the process of flashing the recovery into the device. Everything happens very quickly.

6. At the end of the process, we again see the window already familiar from the previous manipulations “ Download OK". You can reboot into a modified recovery environment.

It is worth noting that the considered method of installing recovery through SP FlashTool does not claim to be an absolutely universal solution. In some cases, when loading the recovery environment image into the device, additional steps may be required, in particular, editing the scatter file and other manipulations.

As you can see, the process of flashing MTK devices on Android using the SP Flash Tool application is not a complicated procedure, but it requires proper preparation and balanced actions. We do everything calmly and think over every step - success is guaranteed!

Program interface

The flashtool interface is intuitive even for a novice user. Consider the main functions of the utility:

Download- the main section of the program responsible for partial or complete firmware of the smartphone. At full firmware smartphone, the entire operating system of the device changes, and with a partial one, you can flash the sections of interest.
readback or backup- a function that helps to return the device to its original state if something went wrong. Actively used when creating a backup.
Format– full formatting of the device.
memory test- a tab that helps to restore. This function will be discussed in more detail in the "creating a backup" section.
Welcome- official instructions for those who launch the utility for the first time. Supporting literature written by software developers.

Application installation

Recommended download the program from the official website of the developer, since this site guarantees the latest and working version of the software, which will be compatible with the maximum number of smartphones based on MTK. Flash tools is not demanding on the technical parameters of the PC, so you need 50 megabytes to install it free space on your hard drive and Windows or Linux operating system.

Before starting the operation, you must prepare all files to the procedure:

What you need to know before starting the firmware

Before proceeding, it is worth observing a series mandatory requirements:

Be sure to back up your data.
Charge the gadget at least up to 60%. Otherwise, the process may terminate incorrectly.
Take several screenshots of the device's desktop so you don't have to remember the location of all the elements.
Clear system cache.

Creating a backup

Backup - important function, allowing you to get a workable operating system in case of any errors while working with file system. To create a backup in the Flash Tool you will need.

Program SP Flash Tool.
Smartphone, running on a meringue MTK processor.
scatter file, which can be obtained from the stock firmware.

Instructions for creating a backup

Run the Flash Tool and download the scatter file in the "Download" tab. If you do not have this file, then you can use scatter from a device with a similar processor.

Note! In order to find out the processor version of your own smartphone, you can download a special application for android OS - AIDA 64, which is freely available.

Useful information! Turn blocks of memory into information familiar look the utility will help wwr mtk .

Recovery in case of failure

If for some reason the tailoring fails, you can restore the backup:

How to flash Android using FlashTool

Phone firmware is a fairly simple procedure. For the convenience of users, we will divide the process into several parts:

Training:

Download and install the MTK driver for your model.
Download and install SP Flash Tool on PC.
Charge your smartphone up to 60% or more.

Installation:

Driver installation:

To install drivers, you need to find in the task manager unidentified device. By right-clicking on an unidentified device, you need to find the "update driver" column. As a folder for drivers, you need to specify the path where they are located (quickly skip all warnings). If the drivers are not installed, then repeat the last three steps described above.

Finalstage:

You can also watch a video with the full firmware procedure:

Possible consequences

Positive sides:

The new version is a fix for minor crashes, increased optimization, and improved work with new programs. Receipt latest version firmware will slightly increase the performance of the smartphone.
Possibility to delete laden software occupies space in the system.
Receipt additional features, which were hidden by the developers. For example, reassigning hot keys.
Increased security with more secure user versions.
Expanding variability in the settings of the visual part.

Negative sides:

Stitched Gadgets are automatically removed from warranty service.
Not all custom firmware that is freely available work properly, so there is a possibility of getting a buggy OS.
Poor custom ROM optimization can cause your phone to drain quickly.
Firmware mismatch with the hardware of the phone can lead to hardware problems, as a result of which some services will start to work more slowly.
The worst thing is the transformation of the phone into a "brick" - an undesirable phenomenon when the phone completely or partially loses its functionality. It can happen if the procedure is performed incorrectly.
