Hi there,

I am currently using a Samsung Mega 6.3 GT-I9205, software version Kitkat 4.4.2 and i would like to upgrade to 4.4.4 and would like to check if there is an offcial Samsung Firware update available. Further, i understand that there is a 4.4.4 usa (T-Mobile) update availble, in that regard could i download it and use it on my phone. I am from Singapore and would appreciate any and all assistance on this.

Thanks!
