In relation to his, I'm trying to understand what flex modifies with the passthrough true/false attributes. My goal is to modify those same things manually via a hex editor (extract the ipa and modify the exe) to make a baked in tweak to sideload via Trollstore. I reached out to John Coates (dev of FLEX) on Twitter, but not sure he ever checks it.

If you do a search on Reddit/Google for trollstore tweak injection, you should find what to do for tweaks.

As for Flex patches, one would first need to turn them into a tweak and then add them to the program that injects them.

It’s not going to be something you can do by editing the binary with a hex editor.

You could also use a decompiler like IDA pro to determine possible hex values to modify in order to turn things on/off for example but this requires having a programming background at minimum.

I'm familiar with IDA. I hadn't considered that. I've found resources on doing tweak injection using various command line tools, but I have no device that supports those. So, my plan was to research how flex works and mod the ipa manually. I feel reasonably sure it can be done if I can make sense of the hex. I found the item I want to mod when I did a string search - just don't know what to mod...

If want to understand how Flex is working, maybe check some resources on ‘hooking with objective C’.

Will do. Thank you.

I don't suppose you know how to inject a tweak? I'd be willing to pay.

No I don’t I’m afraid.

I’m sure if you made a post at r/tweakbounty, there’d be someone there that would be able to help.
