This is a step-by-step guide on how to use Wwr_MTK tool & SP flash tool to backup Mediatek (MTK) firmware. We had previously created guides on how to backup or dump firmware from a Mediatek (MTK) devices; using MTK droid tools , Miracle Box , Infinity CM2 MTK and using SP Flash tool . This guide is going to make use of Wwr_MTK Tool + SP flash tool and it doesn't require that you root the phone before you can make a backup.
What's the advantage of this method over SP Flash tool only dump
When attempting to dump your firmware using SP flash tool only, you'll face two challenges:
Finding a scatter file for your exact phone model (finding one for your chipset doesn't necessarily mean you can use it for a full dump of your phone)
Processing the full ROM_ to get all files in your firmware especially if MTK Droid tools doesn't support your phone. You'll usually need to dump one partition at a time to get around this.
Very Important Notice
If you're following the video guide, also ensure to read / check the text format guide below as there may be some info we'll add as time goes on & new changes are made, these changes may not be available in the video.
If your chipset doesn't appear in Wwr tool then you can manually add it in Wwr window in order to create the temporary scatter file OR modify the template.ini file within wwr folder & include your chipset (we've included a recent template.ini to the requirements section which should contain the most recent chipsets to present day 20/03/2019)
If you try doing a RAM test but all you see in SP flash tool is DRAM flip test, see step 17 in the text guide below. Do NOT perform DRAM flip test on your phone, it takes a long time to complete and may weaken the emmc chip on the phone
Some MTK phones (mostly recent mediatek phones) require a custom download agent (DA) and on rare cases an Auth file in order to perform operations using SP flash tool, you can check our custom DA section OR search online for custom DA for your phone model
Requirements
Download Wwr_MTK tool
Download template.zip & extract template.ini into wwr folder, replacing the existing file (this will add recent chipset types to the list in step 3 in the guide below)
Download SP flash tool
Download Notepad++
Download and Install Vcom Preloader Driver
Windows PC
MTK Phone
Steps to backup a Mediatek Android device's firmware using Wwr_MTK and SP flash tool
Follow the steps below to use Wwr_MTK tool + SP flash tool to backup Mediatek firmware
See the video tutorial below or at
Extract the Wwr_MTK zip file then launch Wwr_MTK_V2.**.exe
When you launch the tool for the first time, the language will be in Russian. To change this, click on "the second item on the toolbar" > Language > English , then restart the tool
Select your device chipset type from the list
Select your memory storage type
Click on "Create and save as"
In the window that opens next, Select the folder location you wish to save the scatter file [this is only a temp and empty scatter file] then click on Save
Edit the scatter file using Notepad++ to get the values for preloader
We'll be using the above scatter file screenshot as an example in this tutorial but take note of the actual values in your own scatter file. The focus at this point is on 3 values
physical_start_addr: 0x0
partition_size: 0x80000
region: EMMC_BOOT_1
When reading back using the SP flash tool readback guide , You are to select the appropriate Region , input the correct Start Address and Length.
Now, use the newly created scatter file to do an SP Flash tool readback of Region EMMC_BOOT_1 and leave the file name as ROM_0 , values are stated below.
Region: EMMC_BOOT_1
physical_start_addr = Start Address
partition_size = Length
Return back to the Wwr_MTK tool, then Click on "Select File" at the top right
