The advantage of this method is that root isn't required and you can obtain a full scatter format dump from nothing but the device and these tools.

In this video tutorial, I'll be explaining how to backup a Mediatek Android phone's firmware using
00:15
WWR_MTK tool and SP Flash tool. We already have a guide on how to dump using SP Flash tool but
00:23
the advantage of this method is that you don't need to have gotten a scatter file for your exact phone model
00:28
okay? Unlike in the SP Flash tool method also that it processes the raw dump into separate files boot
00:38
recovery, preloader and the rest for you. You also need to have installed your VCOM drivers.
00:45
Very important. We have a guide on that so check it out. You need to have taken note of your phone's chipset
00:54
we also have a guide on how to know your phone's chipset. Now, once you've done these,
00:59
what you'll want to do is to open the wwr folder where you're going to be launching the wwr mtk exe file
01:09
and then you wait for the dashboard to come up. Once it comes up, you'll notice that its in Russian
01:25
so you have to change the language. What you do is click on the tab here, click on Language
01:30
and then you click on English. You close the tool then you relaunch it. When it relaunches this time around,
01:43
its going to be in English then we can proceed. I'll resize this ahead of other stuff I'll be doing.
02:25
Now, what you'll want to do is to select your phone's chipset . We have a guide on how to know
02:29
your phone's chipset so check it out. [Selecting my phone's chipset] . Then your memory type.
02:49
emmc or nand. Usually it'll be emmc but you can do some research on your phone's specs
02:57
then you click on Create and save as.. Now, this is going to create a temporary scatter file.
03:02
Navigate to the location where you want to save your scatter file and click on Save.
03:10
That's going to create a temporary scatter file. You can navigate to the location of the scatter file and then
03:19
I'll open using Notepad++ so you can see what it looks like. Its just a temporary scatter file,
03:30
its not a full scatter file like you're probably used to. The goal is just to extract certain values.
03:38
Alright! So we have this scatter file here and we're going to be using some values from the scatter file okay?
03:45
Let's minimize that. Now, we'll launch SP Flash tool. We're going to be doing a readback of preloder.bin.
03:54
Okay? What we want to do right now is to backup preloader.bin using the values from the scatter file
04:01
Just click on OK, this is nothing to worry about. So click on Choose. We're going to be loading the scatter file
04:09
which wwr just created [selecting my scatter file]. Select the scatter file and click on Open.
04:30
That's going to load just one entry in SP Flash tool. So you go to the readback tab
04:39
we're going to be reading back the preloader in two steps; first, readback ROM_0 then process ROM_0
04:50
OK? So you click on Add, that is going to add this row then you double-click this row. A Window will popup.
05:02
Now, in this Window that pops up, you navigate to where you want to save the ROM_0 file
05:06
you leave it named as ROM_0 (don't change the file name) then click on Save. In this Windows that pops up
05:14
under region, you select EMMC_BOOT_1. Under Start Address, just 0x0 (that's the default Start Address.
05:30
Now, under Length, you go to your scatter file. Under partition_size, you copy the value you have there
05:38
then paste it under Length and you click on OK. You're going to readback the raw preloader.bin as ROM_0.
05:51
Click on Readback. Now, power off the phone, still with battery (in), don't hold any button
05:56
then you connect it to the PC via USB cord. SP Flash tool should detect your phone if you have VCOM
06:04
drivers installed and then you should have the bars loading any minute now. We have a red loading bar
06:19
Alright! green OK so you can close this. Now, navigate to the location where you saved the ROM_0 file
06:28
this is the raw preloader file. You still have to process it to preloader.bin [locating my ROM_0] using wwr to
06:40
get my raw preloader.bin. [minimizing notepad++] Go to wwr. In wwr, you click on Select File
06:52
at the top right corner. A window will popup. Now in this Window, select the ROM_0 and click on Open.
07:06
Once the tool has loaded it, you go to the preloader tab then click on Preloader analysis (top left)
