are there any legitimate mod software that work and wont screw me over
No. There are no legitimate Xbox One cheat or modding services at this time. Anyone who claims to provide such services is a scammer.
Nobody has yet found a way to do this for Xbox One. Microsoft are offering a reward of thousands of dollars to anyone who can hack Xbox One. And to date nobody has claimed it.
For now, if you want to cheat on consoles, you’ll need either an Xbox 360, PlayStation 3 or PlayStation 4.
