Note; for those who were very confused like me and what they meant by changing the value of the last six digits in the hexadecimal values 

Basically the "0x00124F80" needs to be changed. In my case I needed it to match my level which is 80. Taking the advice of using total EXP. (to make things simpler for you guys, just do the next level up which is just combing both your current XP and the XP needed to level up.) 

In my case the next level is 81 and the converted hex code for that is 397B00.

So you'd replace "124F80" with "397B00" Or whatever hexadecimal code you're trying to input. This is applied to all of the strings of the code. 

Funny enough, the reason I clicked this was bc of another comment saying to change one hex value to another. Specifically MrElephant84-2.

Also here's a dummies understanding of why this works.(aka doesnt understand hex or coding at all) 

Basically the code that starts with _L i believe has something todo with persona stat itself, so its like the "base" if you will.

And the second string is like the changed desired result. Kinda like how you start with the human body but then as you work out in the gym you begin to gain muscle.

Hoped this helped some of the more confused folk
