Help/Support IDA Offset help

[DemzE 13 iPhone 6 13.3.1]

Ay so I’ve recently started to try make my own tweaks with use of IDA I’m still not 100% sure on what I’m looking for but I think I’ve found the right functions to modify 

I’ve modified this function: Function 1  

I’ve changed the ‘X2’ into ‘X7’ which I believe is meant to make it so the app stores 800+ million instead of its default but again I don’t know if I’ve modified it correctly

And then there’s this function: Function 2

which I recently came across that looks exploitable but I don’t know if it’d be better to exploit this function or the one above or if they’re even exploitable?

Both functions are meant to add coins to my account I know in the the first one I can make STR store 800 million instead and in the second one I thought I could modify the MOV function but not fully sure

Any help is appreciated

You would need to be certain that these functions are "Exploitable" test out the address and see if it does something.

I tried modifying the function through Flex and it worked but it wouldn’t actually stick 

For e.g By default the app is meant to give me +3 coins everytime I like someone’s profile In flex i modified it so instead of giving me +3 it gave me +10 it’d work and give me the +10 but once I’d try to purchase something it’d come up with a error which has me thinking this isn’t exploitable but I thought I could change something in IDA to make it work
