FlashTool - 5.1844.00.000 - FlashTool program is designed to work with Chinese phones. The program provides the ability to read and write full numbers into phones, as well as format

• Genre: Firmware software
• Activation: free, not required
• English language

Firmware MT67**

Please note that smartphones/tablets with 67** chipsets must be flashed with a flash drive with at least version v5.1444.00.000

[*] USB debugging [*]

Don't forget to enable USB debugging!

###-> Instructions for flashing via Flashtool Changing computer settings -> General -> Special boot options -> Reboot now.
When shutting down, click Diagnostics -> Advanced options -> Boot options -> Restart.
Then a menu will appear, in it select “Disable mandatory driver signature verification.

Disabling signature verification on win8.1 is done like this:

Win+I -> Settings -> Change computer settings -> Update and recovery -> Recovery -> Restart now.
When shutting down, click Diagnostics -> Advanced options -> Boot options -> Restart.
After a menu appears, press F7 and wait for the computer to restart.
Next, install the drivers according to the instructions.

When you connect your phone to the computer, you see that your device appears in the “Android Composite ABD Interface” section with a yellow triangle icon, you indicate to the device the path to the driver file, but the device manager insists that everything is fine with the drivers and does not want to update them , then you need to edit the file where you need to register PID\VID, so, you need to first find out this data from your computer. Right-click on the device with the yellow triangle, properties, device ID. There will be 2 lines. These lines need to be duplicated in the driver file. You will then need to re-specify the path to this driver.

Example:

android_winusb.inf - make changes in this file


%SingleAdbInterface% = USB_Install, USB\VID_0BB4&PID_0C01
%CompositeAdbInterface% = USB_Install, USB\VID_0BB4&PID_0C01&REV_0255

vid\pid may change, enter your values

p.s: this is SP Flash Tool - for flashing Chinese devices and more. But don't confuse it with Flashtool for Sony Xperia.

Important information

Please note, if you have MT6575 and MT6577: You only need to flash the preloader and dsp_bl if the brick is lifted! In all other regular updates and flashings, DO NOT check these boxes in the SP Flash Tool and DO NOT enable formatting (then you won’t be able to do anything at home and will take it to the service center). Mindlessly flashing these partitions is a useless and very risky exercise, especially on MT6575 and MT6577.
Try not to flash the preloader file unless absolutely necessary and DO NOT enable formatting (for everyone else)

Copy the folder with the flasher and firmware to the root of the system disk and work from it (don’t create additional problems for yourself)

In different batches of Chinese phones, hardware components are changed that cannot work correctly with firmware for similar devices from the previous batch. The most interesting thing is that they often do not even indicate that this is a different revision. What is this for? And besides, always do a full rom-backup before flashing the firmware.

Smart Phones Flash Tool (SP Flash Tool) is a utility designed for flashing devices built on the MediaTek (MTK) hardware platform and running the Android operating system.

Almost every Android device user is familiar with the word “firmware”. Some heard briefly about this procedure at a service center, others read on the Internet. There are quite a few users who have mastered the art of flashing smartphones and tablets and successfully apply it in practice. It is worth noting that if you have a high-quality and reliable tool - a firmware program - learning to carry out any manipulations with the software of Android devices is not so difficult. One such solution is the SP Flash Tool application.

The hardware-software combination of MediaTek and Android is one of the most common solutions on the market of smartphones, tablet PCs, TV set-top boxes and many other devices, so the SP Flash Tool application is used in most cases when it is necessary to flash MTK devices. In addition, SP Flash Tool is in many situations the only solution when working with MTK devices.

After launching the SP Flash Tool, the application immediately prompts you to proceed to its main function - loading software into the device’s flash memory. This is immediately indicated by the open tab "Download".

The procedure for flashing an Android device using the SP Flash Tool is carried out almost automatically. In general, the user is required to specify the path to the image files that will be written to each section of the device’s memory. The flash memory of an MTK device is divided into many block-sections, and in order to avoid having to manually specify which data should be entered into which memory section, each firmware for the SP Flash Tool contains a scatter file - essentially a description of all sections of the device’s memory in in a form understandable for the firmware program. It is enough to download the scatter file (1) from the folder containing the firmware, and the necessary files will be automatically distributed by the program “in their places” (2).

An important component of the main Flashtool window is the large image of the smartphone on the left side. After loading the scatter file, the message is displayed on the “screen” of this smartphone MTXXXX, where XXXX is the digital encoding of the model of the central processor of the device for which the firmware files loaded into the program are intended. In other words, already in the first steps the program gives the user the opportunity to check the applicability of the downloaded firmware for a specific device. In most cases, if the processor model displayed by the program does not match the actual platform used in the device being flashed, it is necessary to abandon the firmware. Most likely, the wrong image files were downloaded, and further manipulations will lead to errors in the program and, possibly, damage to the device.

In addition to selecting image files, the user is given the opportunity to select one of the firmware modes in a drop-down list.

• "Download"– this mode assumes the possibility of full or partial flashing of partitions. Used in most cases.
• "Firmware Upgrade". The mode only assumes full flashing of the partitions specified in the scatter file.
• In mode "Format All + Download" Initially, the flash memory of the device is completely cleared of all data - formatting, and after cleaning - full or partial recording of partitions. This mode is used only in case of serious problems with the device or in case of lack of success when flashing the firmware in other modes.

After determining all the parameters, the program is ready to record device partitions. To put the USB flash drive into standby mode for connecting a device for firmware, use the button "Download".

Backing up flash memory partitions

The device firmware function is the main one in the Flashtool program, but it is far from the only one. Manipulating memory partitions leads to the loss of all information contained in them, so to save important user data, as well as “factory” settings or a complete memory backup, you will need a backup of the device. In SP Flash Tool, the ability to create a backup becomes available after switching to the tab ReadBack. After entering the necessary data - the storage location of the future backup file and specifying the starting and ending addresses of the memory blocks for backup - the procedure is started with the button "Read Back".

Formatting Flash Memory

Since the SP Flash Tool is intended to be a service utility, the developers could not help but add a flash memory formatting function to their solution. This procedure in some “severe” cases is a necessary step before performing other operations on the device. Formatting options are accessed by clicking on the tab "Format".
After selecting automatic - "Auto Format Flash" or manual - "Manual Format Flash" procedure mode, it starts by pressing the button "Start".

Full memory test

An important step in identifying hardware problems with MTK devices is testing flash memory blocks. The flashtool, as a full-fledged working tool for a service engineer, provides the opportunity to carry out such a procedure. The memory testing function with the selection of blocks required for testing is available on the tab "Memory Test".

reference system

The last section in the program not discussed above, available to the SP Flash Tool user when going to the tab "Welcome" is a kind of help system, where information about the main capabilities and operating modes of the utility is presented very superficially.

All information is presented in English, but even knowing it at the high school level, it is not difficult to understand, and there are also pictures showing actions and their consequences.

Program settings

In conclusion, it is worth noting the SP Flash Tool settings section. The settings window is called up from the menu "Options", containing a single point - "Option...". The list of settings available for change is very scanty and in reality their variations have little effect.

Single window sections "Option", of practical interest are "Connection" And "Download". Using the item "Connection" the hardware interfaces of the computer are configured, through which the device is connected for various operations.

Chapter "Download" allows you to tell the program to check the hash of image files used for transfer to the device in order to check their integrity. This manipulation allows you to avoid some errors during the firmware process.

In general, we can say that the settings section does not allow for serious changes in functionality and in most cases, users leave the “default” values ​​of its items.

Advantages

• The program is available free of charge to all users (many similar service utilities for other hardware platforms are “closed” to ordinary users by the manufacturer);
• Does not require installation;
• The interface is not overloaded with unnecessary functions;
• Works with a huge range of Android devices;
• Built-in protection against gross user errors.

Flaws

• Lack of Russian language in the interface;
• In the absence of proper preparation of devices for manipulation and incorrect user actions, the utility can damage the software and hardware of the device being flashed, sometimes irreversibly.

SP Flash Tool is a reliable program designed for flashing smartphones and tablets running the Android operating system and based on MTK processors. The utility supports work with all models of Chinese-made devices with MediaTek processors, from the oldest to the newly released new products.

One of the most important advantages of SP Flash Tool is its ease of use. The program does not need to be installed on your computer. Simply unpack the archive into the root directory of your local disk and run the executable file. The utility makes it possible to reflash phones, test external memory (RAM) and flash memory for errors, and format flash memory of various types: EMMC, SDMMC, NAND. The functionality of the program allows you to restore the functionality of devices that do not even turn on or immediately freeze upon startup. And support for booting in safe mode "Secure boot" is a fail-safe method for restoring phones infected with viruses. The utility also has the function of creating backup copies of the flash memory of devices, which must be done before flashing the phone's firmware. Another feature of SP Flash Tool is that the program comes with drivers for various smartphones and tablets, which are necessary for correctly recognizing the device with which it will work, which saves users from searching on their own.

On top of that, the SP Flash Tool utility is great for preventative flashing of devices, because updating the phone software will increase its performance and solve the problem with many failures. Today, on the Internet on specialized websites, developers post many different modifications of firmware for smartphones and tablets. Which one to choose for your device is up to you!
