In this video tutorial, I’ll be explaining how to restore
00:13
NVRAM and NVdata to an MTK device using SP Flash tool.
00:19
Usually, you’ll have to do this when you have Null IMEI
00:21
and you have tried other methods like a box
00:24
or Maui Meta and the rest and they just don’t work
00:27
okay? In that kind of case, you have to resort to
00:30
restoring the NVRAM and NVdata
00:33
using SP Flash tool.
00:34
Now, first off, you need to have installed your VCOM drivers. We have a guide
00:37
on how to do that so check out our YouTube Channel and our Forum
00:40
You also need to have the scatter file for your phone model,
00:44
You can get this from the firmware for your phone
00:47
and also the NVdata & NVRAM
00:50
files which you backed
00:51
up from a working phone. Its very important
00:55
you get them from a working phone of
00:57
the same model because if you flash another model’s NVRAM,
01:00
You might corrupt Your NVRAM partition
01:03
so just to be on the safe side, get from a working phone of the same model
01:06
Now, once you have all these in place, the next thing you want to do
01:09
is to modify your scatter file
01:12
Now, I also should mention that you should have installed
01:14
Notepad++. I have that installed on my PC. So
01:19
You open the scatter file using Notepad++
01:21
because that gives you a better view of the contents of the
01:24
scatter file so you don’t
01:27
mix things up. Now, you can see the layout is
01:30
very OK visually.
01:32
Now, what you want to do at this point in Notepad++
01:34
is to search for the NVRAM
01:36
so I’m going type Ctrl + F and
01:39
NVRAM
01:42
and then you tap Enter. So that takes me to the NVRAM section
01:45
of the scatter file. Now, you’re going to change Two values. You have is_download set to false,
01:52
You change that to true.
01:55
This is so that SP Flash tool can detect the NVRAM
01:58
file when you load the scatter file in SP Flash tool
02:01
okay? because if you just load the scatter file without changing these values
02:05
you’ll find out that the list will not contain NVRAM & NVdata okay?
02:10
that’s why we’re going through this step. Now, the next
02:13
thing you want to do is (still under NVRAM) you want to change
02:16
the file name from none to nvram.bin
02:20
This is the file name here. So, nvram.bin okay? I’m done with NVRAM. Over to
02:30
NVdata so you tap Ctrl + F again,
02:34
and nvdata this time around and Enter. Alright! Great! Now,
02:42
here, You change is_download from false to
02:45
true and then under file name, we have that in place so we don’t have to
02:56
make any edit there. So what you want to do is just tap Ctrl + S which is Save
03:02
the scatter file and you can close the scatter file. Now, back
03:06
to SP Flash tool. What you want to do now is to launch SP Flash tool. I recommend using a lower version
03:18
because I tried using the latest version
03:21
and that wouldn’t even let me flash NVRAM at all so I just had to go with this
03:27
particular version. Alright! Great! So in SP Flash tool, what you want to do is to click
03:31
on scatter loading and navigate to the location where the scatter file is.
03:37
You highlight the scatter file then you click on Open.
03:41
That’s going to load the files so you can see NVRAM is ticked
03:45
here and NVdata is also ticked alright? So if I hadn’t made those edits
03:52
You’ll notice that once I load the scatter file, these will not be
03:55
on this list okay? That’s why we had to do the edits earlier on.
03:59
So, I’m ready to flash.What you want to do at this point is to click on Download.
04:04
Alright! Great! So you power off the device which is having
04:07
null IMEI issue. You make sure the battery is inserted, don’t hold any button
04:14
then you connect it to the PC via a USB cord. Wait for detection and flashing. SP Flash tool is flashing…and…
04:23
Yeah, that’s done. So you have the Download OK, great! Then you can close
04:30
SP Flash tool, disconnect and power up the device. Once you boot up, you should dial
04:35
*#06# to check IMEI. You should see that it is restored to your device.
04:41
So that’s basically how to restore NVRAM and NVdata to fix null IMEI on an MTK device
04:48
using SP Flash tool. ————————–
