Extract the Dualtouch.rar from here:

Download the FTF-File for Flashtool Version 0.2.4 or higher:
http://www-stud.uni-due.de/~sfanmakr…_Dualtouch.ftf
Copy this File into the firmwares folder directly, and copy the “Dualtouch” Folder inside the Firmwares Folder of Flashtool. After that just flash your device and reboot, if the ROM is capable of Dual-/Multitouch you will have it now.
Sorry for sounding stupid as I am not a big tech person, but with the Ftf file, what do you mean by directly installing it to the firmwares folder, how do I do it? if you dont mind? would be much appreciated! have mercy on my lack of knowledge!
