I still have an Xbox 360 i’ve never used it to play games just watch YouTube or Netflix but if you do have Xbox live (which you need to play most games, watch YouTube, Netflix etc) you will need to hook it up to internet via Ethernet cable or wireless connection once you have all of it hooked up Xbox live should be running and you should be ready to go. Since the Xbox 360 is pretty old I usually encounter problems with connecting to internet (probably because everything is outdated) so make sure you check for correct pass words and keep trying again if you encounter this problem and you can also disconnect and re connect to get it working almost first or second try! hoped this helps ^-^
I have a puffy battery would it be safe to do this by myself? I' have experience and have done battery replacements before but never with a puffy one, or should I just get a new phone instead?
