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 YouTube 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.
