So I was digging through old Esteem posts and wanted to get the most out of my device, theming(Themeing?) and such. And I got around to using UOT Kitchen and am now left with the "cooked" UOT files and the original rom (MS910 LD-LG V3.5 ZVD) and upon comparison i noticed that the UOT zip I recieved contains only ;"app","framework","META-INF", and "settings"
whereas the ZVD mod contains; "data", "META-INF", "system", "Boot.img" and "install busybox". So the UOT zip seems to be lacking in files and I want to know how to proceed, are these files necessary? I wouldn't want to brick my phone.
and feel free to laugh I know its probably a newbie question lol. I'm new to rooting completely I'm still having trouble with terminology
So explain it to me like i'm 5 
THANKS IN ADVANCE!
