[theshotof]

hello masterminds and noobs... 1st let me take a sec to thank the guys who make the roms there pretty cool..
but now i have a question i am using nob rom 4.4.4 and its works great with stock kernal.. butter smooth page to page everyone is telling me i should be using 5.1 ( if there is nothing wrong with this wrong wy change is 5.1 better)? and if so explane also is there a true app that moves apps to sd i tryed them all and nothing, and few more things the phone speacker sucks and the hands free speacker also sucks any mods on fixing that and how do i make this phone louder so it doesnt sound like its in a metal trash can?




any help would be great with links and step by step due to the fact i am a nob and damn proud of it lol...

If you need to back up apps to re install them on a different ROM, use titanium backup and back up all apps with their data then restore them on your all new ROM!

Will this work with games? Lol I'm a mortal kombat freak and this game is preventing me from trying other ROMs lol I've got so much time invested haha
