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

Almost every user of the Android device is familiar with the word "firmware". Someone has heard a glimpse about this procedure in the service center, someone read on the Internet. Not few of these users who mastered the art of firmware smartphones and tablets and successfully apply it in practice. It is worth noting that in the presence of high-quality and reliable tools - a program for firmware - learn to carry out any manipulation with software Android devices are not so difficult. One of these solutions is the SP Flash Tool application.

MEDIATEK and Android hardware combination is one of the most common solutions in the smartphone market, tablet PCs, TV consoles and many other devices, so the SP Flash Tool application is used in most cases, if necessary, make the MTK-devices firmware. In addition, SP Flash Tool is in many situations a non-alternative solution when working with MTK devices.

After starting the SP Flash Tool, the app immediately proposes to perform the main function - downloading software to the device flash memory. This speaks immediately open tab "DOWNLOAD".

Android device firmware procedure using SP Flash Tool is carried out practically in automatic mode. From the user, in general, you need to specify the path to image files that will be recorded in each section of the device's memory. Flash memory MTK device is divided into multiple partition blocks and in order not to manually point exactly what data and which memory item to enter, each firmware for SP Flash Tool contains a scatter file - essentially a description of all sections of the device's memory in understandable for the program-firmware form. Just load a scatter file (1) from the folder containing the firmware and files Automatically distributed by the program "in its place" (2).

An important component of the Main Window Flashtool is big picture Smartphone in the left side. After downloading the scatter file, the "screen" of this smartphone is displayed. Mtxxxx.where xxxx is a digital model encoding central processor Devices for which the firmware downloaded to the program are designed. In other words, the program already in the first steps gives the user the ability to check the applicability of the downloaded firmware for specific device. In most cases, if the processor model displayed by the program does not coincide with the real platform used in the device being stitched, it is necessary to refuse firmware. Most likely incorrect image files downloaded, and further manipulations will result in errors in the program and, possibly, damage to the device.

In addition to selecting file-images, the user is given the ability to select one of the firmware modes in the drop-down list.

• "DOWNLOAD" - This mode assumes the possibility of a complete or partial firmware of sections. Used in most cases.
• Firmware Upgrade. The mode is assumed only full firmware Sections specified in the scatter file.
• In mode "FORMAT ALL + DOWNLOAD" Initially, a complete cleaning of the device flash memory is performed from all data - formatting, and after cleaning - a complete or partial partial entry. This mode applies only with serious problems with the device or in the absence of success when firmware in other modes.

After defining all parameters, the program is ready to record device partitions. To transfer the flash station to the standby mode, the button for the firmware is used. "DOWNLOAD".

Backup Flash Memory Sections

The device firmware function is the main in the flashlight program, but far from the only one. Manipulations with memory sections lead to the loss of the information contained in them, so to save important user data, as well as the "factory" settings or a full backup of the memory, you will need a device backup. In the SP Flash Tool the ability to create a backup to become available after the transition to the tab "READBACK". After making the necessary data - the storage locations of the future backup file and the instructions of the initial and end address of the memory blocks for the redundancy - the procedure is started by the button «READ BACK».

Formatting flash memory

Since in its destination SP Flash Tool is a service utility, the developers could not not add a flash memory format function to their solution. This procedure in some "severe" cases is a necessary step before carrying out other operations with the device. Access to formatting features is carried out when switching to the tab. "Format".
After selecting automatic - "AUTO FORMAT FLASH" or manual - "MANUAL FORMAT FLASH" Procedure mode, it starts to press the button "Start".

Full memory test

An important step when identifying hardware problems with MTK devices is to test flash memory blocks. Flashtool, as a full-fledged working tool of the service engineer, provides the ability to carry out such a procedure. Memory test function with the choice of the required blocks is available on the tab. "Memory Test".

reference system

The latter not considered above in the program available to the user SP Flash Tool when you go to the tab "Welcome" - It is peculiar reference systemwhere the information about the main possibilities and modes of operation of the utility is very superficiated.

All information is set forth on english languageBut even knowing it at the level of high school, it is not difficult to understand, besides there are pictures that displays actions and their consequences.

Programs settings

In conclusion, it is worth noting the SP Flash Tool settings section. Calling the settings window is made from the menu "Options"containing the only point - "Option ...". The list of settings available for change is quite sozden and in reality their variations are not enough for what.

Single window sections "OPTION"representing practical interest is "Connection" and "DOWNLOAD". With the help of item "Connection" The computer's hardware interfaces is configured through which the device is connected for various operations.

Section "DOWNLOAD" Allows you to specify the program to check the hash-sum of the image files used to transfer to the device to check their integrity. This manipulation allows you to avoid some errors in the firmware process.

In general, we can say that the settings section does not provide a serious change in functionality and in most cases users leave the values \u200b\u200bof its default items.

Dignity

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

disadvantages

• 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 part of the device being stitched, sometimes irretrievably.

FlashTool is a powerful tool intended for the firmware of smartphones operating on the MediaTek chipset. With this application you can how to install on your device more new version The operating system is to replace it with custom (third-party developers modified).

However, this whole process is accompanied by a certain risk, and one incorrect effect may result in the fact that your smartphone will turn into a useless "brick". To do not happen, carefully read this article. From it you will learn about how to flash through FlashTool correctly and do not risk the phone in vain.

Determine the processor model

As mentioned earlier, FlashTool works only with devices based on MediaTek. In view of such a feature, it is important to make sure that your smartphone is equipped with a processor of this manufacturer, otherwise the program for the firmware may incorrectly interact with it. This, in turn, is fraught with serious consequences.

To determine the processor model, you will need special application - CPU-Z. You can download it for free. Play Market.So this process should not cause you any difficulty. After you download and install the program, do the following:

1. Run CPU-Z on your smartphone.
2. Wait a few minutes while the program will collect information about the device.
3. Click the SOC tab and pay attention to the upper line. It is here that the model of your processor will be displayed.

If mediatek is written in the above-mentioned line, then your smartphone is suitable for working with the program. But still, before flashing through FlashTool, you need to perform several more important actions. We will talk about them below.

Preparation

It is important to know that the smartphone firmware will lead to the fact that he will return to his factory settings. In other words, all the information stored on the device will be deleted, and it will not be restored. So that it is not for you trouble, do the following:

• Save all contacts from phonebook. They can be transferred to a computer with special programs Or synchronize with your Google Account.
• Copy on your computer all important photos, documents and videos.
• Check if anyone left in SMS important information (passwords from payment systems, bank codes, etc.). If there is something available, it is better to rewrite it.
• Check the calendar for the presence of significant dates.
• If you have left setup files Some rare programs, you can copy them to a computer before flashing through FlashTool.

Do not neglect these simple advice, because they will help you save time and nerves. It is better to go through all the items several times, and only after that proceed to the firmware.

Setting up the operating system

Before flashing "Android" through FlashTool, you need to set some settings for the operating system. The fact is that Windows does not adequately perceive the smartphones drivers, so you need to cancel the check digital signatures. This is done like this:

1. Launch command line (Administrator).
2. Write a gpedit.msc command for a 32-bit OS or C: \\ Windows \\ syswow64 \\ gpedit.msc for a 64-bit OS. Press ENTER.
3. Before you will open "Editor group Policy" Here you need to choose the "user configuration", then "administrative patterns", and then "system".
4. Now click "Install Driver", and then select "Digital Signature".
5. In the window that opens, select "Disable".
6. Click "OK" and confirm the changes made.

Now the operating system will not "swear" to the smartphone driver, and the firmware program will be able to work normally.

Installation of smartphone drivers

At this stage you need to download and install a driver for your device, which will allow it to interact with the computer normally. It follows in such places:

• First of all, the driver must be sought on the website of the manufacturer's manufacturer of your device. So you will be sure that do not pick up a computer virus.
• Sometimes the driver can be found on the disk, which comes complete with some models of phones. If so, then you need to insert a CD into a computer drive and follow the prompts.
• In the event that the two above mentioned methods are not suitable for you, you can search the driver on thematic forums. Keep in mind that so you risk security not only your phone, but also a computer. Therefore, be sure to check all downloaded files for viruses before installing them.

After you find a driver, it should be downloaded and installed. This is done by double clicking on the archive and should not cause any difficulties. But sometimes problems still arise, therefore such cases should be paid to a separate attention.

Driver Installation Problems

It often happens so that the driver does not want to be installed. In fact, there is nothing terrible in this, and the problem is solved quite simply. Namely:

1. Disconnect the DATA cable from the computer and the phone.
2. Turn off your smartphone and get the battery from it. You can not remove the memory card and the SIM card.
3. Open the Device Manager on your PC.
4. Place the driver files at any place convenient for you.
5. Without inserting the battery, connect the phone to the computer and get ready.
6. Literally for a few seconds, a new device will appear in the dispatcher. You need to have time to click on it with right mouse button and select the "Update Driver" string.
7. Now simply specify the path to the driver files and wait for the installation process.

If you have not managed to update the phone driver in time and the device disappeared from the dispatcher, you need to repeat the entire procedure again, starting from paragraph 5.

Search for firmware

Now it's time to find and download the firmware that you will install on your smartphone. Here you have two options: use the official software or custom. In the first case, just go to the phone manufacturer's website and find last update For your model. But if you decide to use custom firmware, then you should adhere to a few simple rules:

• Make sure the selected firmware is suitable for your smartphone model. Failure to comply with this condition is fraught with serious problems, up to the transformation of the phone into a "dead" piece of plastic.
• Download files only with reputable sites and forums. In this case, even if some problem arises, you can count on the help of software developers.
• Carefully examine reviews about the firmware left by other users. Better do not risk if there are many negative among them.
• Make sure that the smartphone firmware installed with you is older than that you are going to download.

Remember, observing these simple rules, you will save your phone from unnecessary breakdowns.

Creating a backup

Most users do not have problems during the firmware, and the whole process goes smoothly. But still it is better to prepare for unforeseen situations in advance, because no one is insured against them. To do this, you need to create backup Smartphone system files before flashing through FlashTool. For this:

1. Connect the phone to the computer.
2. Select read speed.
3. Specify the type of reading NOR.
4. Click the Read BACK tab and click Add. Create a backup file by assigning any name to it. After that, press SAVE.
5. You will appear in front of you in which you should specify the size of the read data in the Length field. For a start, try entering the value 0x01000000, and if it does not fit, then 0x02000000.
6. Disconnect the phone from the cable and turn it off. Remove the battery, insert it back, and then re-connect the smartphone to the DATA cable (not including).
7. Click and immediately release the smartphone's power button.

If you did everything correctly, the backup process will begin. Be sure to wait for his end.

Firmware device

If you are all thought and prepared, you did not have anything else left, except to flash through FlashTool. Instructions for this procedure, in fact, not so complicated, and it looks like in the following way:

1. Start Falshtool and click Scatter-Loading.
2. Specify the path to the mtxxxx_android_scatter_emmc.txt_scatter_emmc.txt (instead of "XXXX" there will be numbers that correspond to your device processor models). Click "Open".
3. Be sure to check the checkbox DA DL All WITH CHECK SUM. Otherwise, you risk "kill" your smartphone.
4. Click the Firmware-Upgrade button and connect the connected phone.
5. At the bottom of the main menu of the program, multi-colored loading bands will appear.
6. As soon as the firmware process is completed, a green circle will appear on the screen, which notifies the successful operation.

Now you can turn off the smartphone from the DATA cable and use it. Keep in mind that the first inclusion of the phone sometimes takes quite a lot of time, so do not worry if you have such a situation.

By the way, if you do not know, via FlashTool, then you can use the same instructions. It is equally valid for all devices based on Android.

Firmware Chinese phones

How to flash chinese phone via FlashTool? It is also possible to do, but this procedure is somewhat different from the standard one, it will be considered separately. It is important to know the following here:

• Never press the Memory Test button in Flashtool. For some reason chinese phones Inadequately react to this operation, and it can happen that the firmware will be erased without the possibility of recovery.
• Carefully examine information about the firmware on the site from which you download it. It is possible that there are bugs that can cause serious problems with you.

That's basically it. Now you can enjoy new firmwarewhich will undoubtedly make your smartphone work in a new way.

Sp Flash Tool - Smart and convenient tool designed to firmware devices built on the basis of MediaTek chipsets. If you decide to flash an Android smartphone or a tablet with such a processor "under the hood", then you need to take care of the opportunity to make backup ROM apparatus if something goes wrong. In addition to the usual reason (precautions), there is another reason here: not every firmware you chose can approach specifically for your device. Therefore, it is necessary to make sure that the requirements for the characteristics of the display, the amount of memory and the other regulated new firmware parameters are fully observed. Otherwise, the software, and with it the device, may be partially or completely inoperative. Practice shows that when the Android-smartphone firmware is coincided with the SP Flash Tool, it goes smoothly, but we still decided to lead the backup instructions.

Creating a full backup of the flash memory of the smartphone

1. Run the flash drive, then in the "Download" tab, download the scatter file (it can be borrowed from the Android device with a similar processor). Do not be afraid if you do not see any firmware files in the folder with the Scatter file - this is normal. Leave a tick on the first line (Preloader), remove the rest.

2.2. Through the USB port, connect the android device turned off to the PC;

2.3. The memory test that will occur after the connection will show you the information you need on the EMMC blocks (not pay attention to the blocks with zero volume, you will need only having size;

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

note : on the device taken as an example, there are 4 regions, but this does not mean that they are as much on other gadgets. Flash memory can be 3, 2 or even one region ("User"). In the latter case, you do not have to choose the region - in the menu, designed to enter the block read options, this option will be absent. As a rule, this situation happens when working with Android devices based on chipsets early years release.

3.4. Press the "READBACK" button, reconnect to the USB port of the off gadget - reading will begin;

3.5. After the block reading is completed, repeat the manipulation described in clause 3 with all other regions.

So you get a full copy of your Android flash memory.

SP Flash Tool - Program for the firmware android devices based on MediaTek chips (MTK). Unfortunately, sometimes quality chinese firmware leaves much to be desired, otherwise the manufacturer stops updating the phone. Some functions stop working, the smartphone begins to quickly discharge and the desire to acquire a new one appears. Extend to him life will help independent flashing with popular program SP Flash Tool and Computer.

Capabilities

Note! During the firmware, unforeseen situations may occur. All actions The user performs at its discretion. Download data using third-party program Can lead to errors. It should be previously examined on specialized precautions forums, detailed instructions And choose the working version of the firmware of your smartphone. This is especially true for custom (created by simple users based on official) software. The manufacturer will refuse B. warranty service When the "unofficial" intervention is found in the operation of the device.

The SP Flash Tool program has such features:

• firmware / flashing the original version of Android. Manufacturers often forget about their creations, even came out not so long ago. Android version with new frills may not come to the phone. But if its characteristics allow you to install it, then you can do it using a computer and Flash Tool. There are such cases: the manufacturer itself adds its own innovations into the usual firmware. You can put a "clean" version if they did not like to taste. Moreover, they work freeze. The flashing saves from the brakes of the system, removing the extra and accumulated garbage.
• firmware with custom (unofficial) software. Special for third-party developers improves performance, appearance And adds previously inaccessible capabilities.
• getting root rights (superuser). Opens a previously unavailable opportunity for a simple user. The manufacturer specially underestimates the characteristics of the phone (for example, that the volume level invested in the permitted indicators of the EU special commissions) - this can be corrected.
• installing third-party recovery (recovery). Allows you to make a backup or restore from it, install custom firmware, updates and fixes OS, format a memory card, etc.

Before the firmware you need to fully charge the phone, otherwise it slows down the battery. And if it is not enough for the whole process, it will lead to errors or a complete breakdown.
