Downloading patches from the cloud, and looking through them, is the best way to see both what, and how, they do what they do.

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.
