Samsung Galaxy W SGH T679M Bell Canada Android 2 3 5 Stock ROM

The stock ROM T679MUGKK1 is the Original Operating System of brandedSamsung Galaxy W SGH-T679M by carrier Bell Mobility in Canada. This smartphone source released by Samsung has kernel and system differences, but the hardware specs are pretty much identical to the international version of Samsung Galaxy W GT-I8150 and the Samsung Exhibit II 4G SGH-T679 by T-Mobile in USA but it uses a different firmware because it is branded exclusively by Bell Mobility Canada. 

I got this info with AnTuTu, so I figured out that this is an Android 2.3.5 Gingerbread firmware version.
