Is his SplitFUS tool too complicated for you? Or you have a problem with it?
Well today is your day! This tool (Odinatrix) does exactly what SplitFUS does, but with simpler use. Just extract the file (preferably to your home directory) and put your unsplitted Samsung FUS files in the folder it creates! Then wait.... That's all! It works (I tested it with my NZ S5360T running Jelly Blast V3)
I'm just posting this to help noobs. I did not code it (I am noob too ). All credits go to ACervellati and Doc_cheilvenerdi for coding this awesome tool!
Hit THANKS if it helped!
