In this video tutorial, I'll be explaining how to use SN Write tool also known as SN Writer
00:30
In previous guides, I'd explained how to fix Null IMEI and WiFi 0x10 NVRAM errors
00:38
using either MTK Engineering or WiFi.exe manual editing and creation
00:44
but the limitation of those methods is that once you do a factory reset, they revert to previous state
00:54
in the sense that if you write IMEI to your phone using the MTK Engineering method and you do a factory reset
01:00
its very possible your IMEI disappears so you're back to null IMEI but if you're having the 0x10 NVRAM error
01:09
before the fix, once you do a factory reset, you're back to that error. So they're temporary fixes.
01:16
Its not like they're not effective but they just disappear once you do a factory reset.
01:22
Now, the advantage of using SN Write tool is that you have a permanent fix in the sense that even if you
01:28
do a factory reset, your IMEI still remains and your WiFi / MAC address, 0x10 is gone for good
01:38
even if you do a factory reset. That is one advantage you have when you use SN Write tool or SN Writer
01:44
Now, the downside is that you need to have the MD1DB & APDB files for the phone you're trying to fix
01:59
and these files are located in the firmware for that phone so unless you have a firmware with those two files in them
02:07
you will not be able to use SN Write tool. So you'll need those two files for SN Write tool
02:15
that is why I said its kind of a downside but with the other methods, you do not need any file
02:19
just the phone and you're good to go. Before you can use SN write tool, you need to have your drivers installed
02:28
so i'll be showing you how to install drivers for Feature phones and Mediatek Android (smart) phones.
02:35
Ideally, I should not be taking you through this guide of installing drivers but just to give you a start to finish
02:42
approach, I will just take a few minutes out to put you through that. Alright! So for Feature phones,
02:50
what you have to do is download the drivers. You can check the SN Write tool guide at the Forum. You'll
02:56
find the link to download these drivers. You just open the folder and double-click InstallDriver
03:06
Now, for the MTK USB VCOM drivers, you need to disable driver signature verification
03:17
if you're using a Windows 8 or 10 PC. We already dropped a guide at the Forum and you can check our
03:24
KZbin channel for the guide on how to disable signature verification on a Windows 8 or 10 PC
03:31
so you do not encounter any error during the Mediatek VCOM driver installation. If you're using a Windows 7 PC
03:41
you do not need to do that. Its disabled by default. There's no setting that will block your driver installation
03:50
by default on a Windows 7 PC but for Windows 8 and 10, you need to disable that.
03:56
Now, the reason is that this Mediatek USB VCOM driver you're looking at is an unsigned driver.
04:01
Windows 8 and 10 tend to block the installation of unsigned drivers unless you disable that check
04:09
you understand? So that's what you're trying to do on a Windows 8 and 10 PC.
04:13
Alright! So I'll get down to the installation of Mediatek USB VCOM drivers
04:17
and you'll want to open Device Manager. For that you tap the Windows button and type device manager
04:26
Alright! Once in device manager, what you'll want to do is to select any item on the list
04:34
then you click on Action - Add legacy hardware - Next - Install the hardware that I manually select from a list -
04:44
Next - Next - click on Have Disk. Now, you click on the Browse button and navigate to the location of the USB
04:59
VCOM drivers. You open Mediatek USB VCOM drivers - Drivers - USB VCOM Driver
05:08
Now, if you're using a Windows 7, 8 or 10 PC, you select the Win7 folder but for Vista & XP, select the ones above.
05:21
This would work for Windows 7,8 & 10 so you just open that. Now, you need to select the right one for your
05:30
PC's architecture. If you're using a 32 bit PC, you'll want to select this. If you're using 64 bit, select this.
05:38
Now, to check which your PC is, you right-click on Computer - Properties. Mine is a 64 bit PC so
05:53
I'll go ahead and select the 64 bit version and click on Open and click on OK.
05:59
As you can see, this driver is not digitally signed. Click on Next - Next and wait for installation to begin.

Thanks for this video, I managed to solve my problem and write IMEI and MAC successfully. APDB and MD1 files are in the phone's ROM folder If you don't have it then down load it from the shortcut in the "AP BP Base" folder which is in "SN writer tool" folder.

Thank you very much! It actually works, unlike the many worthless google tutorials and sites. The firmware is in the ROM folder(unzipped from an archive as ".zip" file). Make sure your ROM has the databases. Maybe you can use from another ROM. !!! Don't forget to install all the drivers, not only the first one from the list !!!
