The MTK hardware platform as the basis for building modern smartphones, tablet computers and other devices has become very widespread. Along with the variety of devices, the ability to choose variations of the Android OS has come into the lives of users - the number of available official and custom firmware for popular MTK devices can reach several dozen! To manipulate 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 software installation process through the SP FlashTool application is generally the same and is carried out in several steps. Let's look at them in detail.
All actions to flash devices using SP FlashTool, including following the instructions below, are carried out by the user at his own peril and risk! The site administration and the author of the article are not responsible for possible malfunction of the device!
Preparing your device and PC
In order for the procedure of writing image files to device memory sections to go smoothly, it is necessary to prepare accordingly by carrying out certain manipulations both with the Android device and with a PC or laptop.
- We 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.
- It is advisable that the names of the folders for the location of application and firmware files do not contain Russian letters and spaces. The name can be anything, but you should name the folders consciously so as not to get confused later, especially if the user likes to experiment with different types of software loaded into the device.
- 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:
- We make a system backup. Regardless of the outcome of the firmware procedure, the user in almost all cases will have to restore his own information, and if something goes wrong, the data that was not saved in the backup copy will be irretrievably lost. Therefore, it is highly advisable to follow the steps of one of the methods for creating a backup from the article:
- We ensure uninterrupted power supply for your PC. Ideally, the computer that will be used for manipulation via SP FlashTool should be fully operational and equipped with an uninterruptible power supply.

Installing firmware
Using the SP FlashTool application, you can perform almost all possible operations with device memory sections. Installing firmware is the main function and to perform it, the program provides several operating modes.
Method 1: Download Only
Let's take a closer look at the procedure for downloading software to an Android device when using one of the most common and frequently used firmware modes via SP FlashTool - “Download Only”.
- Launch SP FlashTool. The program does not require installation, so to launch it, simply double-click on the flash_tool.exe located in the application folder.
- When you launch the program for the first time, a window with an error message appears. This point should not worry the user. Once the path to the location of the necessary files is specified to the program, the error will no longer appear. Click the “OK” button.
- In the main window of the program after launch, the operating mode is initially selected - “Download Only”. It should be noted right away that this solution is used in most situations and is basic for almost all firmware procedures. The differences in operation when using the other two modes will be described below. In general, we leave “Download Only” unchanged.
- Let's move on to adding image files to the program for further recording in the device's memory sections. To automate the process somewhat, SP FlashTool uses a special file called Scatter . This file is essentially a list of all partitions of the device’s flash memory, as well as the addresses of the starting and ending memory blocks of the Android device for writing partitions. To add a scatter file to the application, click the “choose” button located to the right of the “Scatter-loading file” field.
- After clicking on the button for selecting a scatter file, an 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 is named MT xxxx _Android_scatter_ yyyyy .txt, where xxxx is the model number of the device processor for which the data loaded into the device is intended, and yyyyy is the type of memory used in the device. Select the scatter and click the “Open” button.
- 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. This procedure can be canceled during the verification process or disabled in the settings, but this is strictly not recommended!
- After downloading the scatter file, the firmware components were automatically added. This is evidenced by the completed fields “Name”, “Begin Adress”, “End Adress”, “Location”. The lines under the headings contain, respectively, the name of each partition, the starting and ending addresses of the memory blocks for recording data, as well as the path where the image files are located on the PC disk.
- 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 “PRELOADER” section; this allows you to avoid many 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.
- Checking the program settings. Click the “Options” menu and in the window that opens, go to the “Download” section. We check the boxes “USB Checksum” and “Storage Checksum” - this will allow you to check the checksums of files before writing to the device, and therefore avoid flashing corrupted images.
- After completing the above steps, we proceed directly to the procedure for writing image files to the appropriate sections of the device’s memory. We check that the device is disconnected from the computer, turn off the Android device completely, remove and reinsert the battery if it is removable. To put SP FlashTool into standby mode for connecting the device for firmware, press the “Download” button, indicated by a green arrow pointing down.
- While waiting for the device to connect, the program does not allow you to perform any actions. Only the “Stop” button is available, which allows you to interrupt the procedure. We connect the switched off device to the USB port.
- After connecting the device to the PC and identifying it in the system, the process of flashing the device will begin, accompanied by the filling 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. To fully understand the processes occurring during firmware, let’s look at the decoding of the indicator colors:
- After the program has completed all the manipulations, the “Download OK” window appears, confirming the successful completion of the process. We disconnect the device from the PC and start it by long pressing the “Power” key. Usually the first launch of Android after flashing takes quite a long time, you should be patient.
Attention! Loading an incorrect scatter file into the SP Flash Tool and further recording images using incorrect addressing of memory sections can damage the device!
Method 2: Firmware Upgrade
The procedure for working with MTK devices running Android in the “Firmware Upgrade” mode is generally similar to the “Download Only” method described above and requires similar actions from the user.
The difference between the modes is the impossibility of selecting individual images for recording in the “Firmware Upgrade” option. 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 the official firmware of the entire working device if the user requires a new version of the software, and other update methods 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” mode involves completely formatting the device’s memory, therefore, all user data will be destroyed in the process!
The firmware process in the “Firmware Upgrade” mode after clicking the “Download” button in SP FlashTool and connecting the device to the PC consists of the following steps:
- Creating a backup copy of the NVRAM partition;
- Complete formatting of the device memory;
- Write device memory partition table (PMT);
- Restoring an NVRAM partition from a backup;
- Recording all partitions whose image files are contained in the firmware.
The user's actions to perform firmware upgrade in the "Firmware Upgrade" mode are the same as the previous method, with the exception of certain points.
- Select the scatter file (1), select the SP FlashTool operating mode in the drop-down list (2), press the “Download” button (3), then connect the turned off device to the USB port.
- Upon completion of the procedure, the “Download OK” window will appear.
Method 3: Format All + Download
The “Format All+Download” mode in SP FlashTool is intended for flashing firmware when restoring devices, and is also used in situations where the other methods described above are not applicable or do not work.
The situations in which “Format All+Download” is used are varied. As an example, we can consider a case where modified software was installed in the device and/or the device’s memory was re-partitioned to a solution different from the factory one, and then it was necessary to switch to the original software from the manufacturer. In this case, attempts to write original files will fail and the SP FlashTool program will suggest using emergency mode in the corresponding message window.
There are only three stages of performing firmware in this mode:
- Complete formatting of the device memory;
- PMT partition table entry;
- Record all sections of the device memory.
Attention! When manipulated in the “Format All+Download” mode, the NVRAM partition is erased, which leads to the deletion of network parameters, in particular, IMEI. This will make it impossible to make calls or connect to Wi-Fi networks after following the instructions below! Restoring an NVRAM partition in the absence of a backup is quite a labor-intensive procedure, although it is possible in most cases!
The steps required to format and write partitions in the “Format All+Download” mode are similar to those in the methods described above for the “Download” and “Firmware Upgrade” modes.
- Select the scatter file, determine the mode, and click the “Download” button.
- We connect the device to the USB port of the PC and wait for the process to complete.

Installing custom recovery via SP Flash Tool
Today, so-called custom firmware has become widespread, 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 of changing and expanding the functionality of an Android device, it is worth noting that installing custom ones in most cases requires the presence of a modified recovery environment in the device - TWRP Recovery or CWM Recovery. This system component can be installed in almost all MTK devices using SP FlashTool.
- Launch Flash Tool, add a scatter file, select “Download Only”.
- Using the checkbox at the very top of the list of sections, uncheck all image files. Check the box next to the “RECOVERY” section only.
- Next, you need to specify the program the path to the custom recovery image file. To do this, double-click on the path specified in the “Location” section, and in the Explorer window that opens, find the required *.img . Click the “Open” button.
- The result of the above manipulations should be something similar to the screenshot below. Only the “RECOVERY” section is checked; in the “Location” field the path and the recovery image file itself are indicated. Click the “Download” button.
- We connect the switched off device to the PC and watch the process of flashing the recovery firmware into the device. Everything happens very quickly.
- At the end of the process, we again see the “Download OK” window, already familiar from previous manipulations. You can reboot into a modified recovery environment.
It is worth noting that the considered method of installing recovery via SP FlashTool does not pretend to be an absolutely universal solution. In some cases, when loading a recovery environment image into the device, additional actions 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 about every step - success is guaranteed!
