Hi! I'm new here and I really need an experienced help. You see, I've been playing games on my 4GB Xbox slim but it can't play new games like watchdogs and needed an update. How exactly do I update my Xbox? Is it by using simple 360 nand flasher and xebuild or I watched a YouTube video where I just need to download the new update on the official XBox site and put it in my USB and then update. Please help me because I'm a total noob about this. Please someone reply. Thank you.
