Help/Support How to add a dylib to an .ipa file to tweak an app for non-jailbroken devices

i0s_tweak3r · July 4, 2018

I noticed when side loading a game cheat the dylib for the cheat was added as part of the process, which I assumed was the case. I bought a new device somewhat recently that I decided to use as my daily driver but would love to add some tweaks to certain apps, especially ones already available but with tons of ads. I know this is a really stupid question, but is it just a matter of extracting the payload of cracked app and adding it to a particular location or is it more involved, like adding a mod telling the binary to load it?

Also second unrelated question- I've been thoroughly enjoying having a developer account and want to make sure it doesn't get banned / have all side-loaded apps revoked. As long as I'm the only one adding apps, do I need to worry about adding game cheats and other cracked apps to an unjailbroken device using my developer account for the provisioning profile or as long as it's not being widely distributed should I be fine? I do have several Apple hosts blocked with an adblocker, including oscp.apple.com, just not positive if it blocks it when using a separate VPN so my ISP doesn't detect piracy.

Out of interest, I would like to know the answer to this question too.

Unfortunately it probably requires a knowledge of how to create an app, which I don't have but you do ?

I'm guessing you don't need to know how to make an app, unless maybe the dylib gets added in by making an app using Theos then converted into an .ipa. I'm pretty sure it's simpler tho.

(Maybe Xcode is required which I'm working on adding a virtual version to my PC....really wishing I had a Mac because I'd be jailbroken already with multi_path exploit.)

Maybe you should try and get one.

When you're sideloading a game cheat, there will be a dylib created with the tweak.xm content.

This Tweak.xm only contains such things as a popup & iGAuth. Not direct code injection itself, cause that's not possbile on NJB.

But this is about NJB hacks from this forum, other sideloaded apps like Instagram++ don't really use offsets from the binary like we do with games, it's own written obj code.

With theos-jailed you can compile your Tweak.xm code, which makes a dylib out of it & then injects it to the App.

You can also inject other dylibs. Paste the dylib in the root directoy of your project & then add this line in the Makefile of your theos-jailed project folder:

TWEAK_NAME_INJECT_DYLIBS = tweak-name.dylib
