Help/Support Modding IPA exe via HxD (hex editor)

[Drivium 14 iPhone 7 10.3.2]

Long story short, I have a jailed iPhone with Trollstore. I want to mod an app to sideload. It must be possible to mod ipa's via hex, I just don't know what to look for. See the attached screen shots. Hoping someone can help me understand what FLEX reads behind the scenes so I can do it manually in hex.  Such as what pass-through, True, and False look like in the code. Thanks in advance!

Grab the real offset of what you want to hack. Like Gems or something. Search it in hxD and replace the hex to for example  0090261EC0035FD6. 

True = 20008052 // C0035FD6 = RET
False = 00008052 // C0035FD6 = RET

mov w0, #1 = True
mov w0, #0 = False

Offset is probably wrong. or the hex is too high
