Okay, so the very first time I found out you could mod money and RP using a simple program, I jumped straight in and no matter what I did I COULD NOT get it working. The next day I found a solution and it worked first try!

It's Wan5's server I do believe! I will leave the info below!

173.236.164.205 prod.cloud.rockstargames.com #Server 2

Open your Hosts file in either Sublime Text 2 or Notepad and go to the bottom where it says something like:
# ::1 localhost (And do as you see below)
173.237.164.205 prod.cloud.rockstargames.com #Server 2

Now save it, and then boot up your xbox and load GTA 5 online and you will have working mods, guaranteed.

It's just as simple as that (:

But I do warn you to be careful because within 6 hours of having and using the mods I was banned from GTA Online, and put into a cheaters pool lobby and am stuck in it forever and can't play with my friends or even do jobs.... So if you're gonna do this, don't do it non stop all day like I did but split it up and do it here and there but just realize rockstar is watching and has caught on and eventually they will ban you from the normal server!
