Help/Support IDA HEX hacking via Tweak.xm

sm0ke · March 15, 2019

Hi all,

I am new to the tweak scene. I have found some hacks by changing the hex at specific offsets in IDA.

For example

ADD r0, r0, #instancevar

to

ADD r0, r0, #0

Is it possible to be able to turn these on/off with the in game menu?

i was thinking something like the mshook so the values can be on/off rather than hardcoded in the binary.

Thanks

This can be done, on jailbroken devices. Non-jailbroken devices don't have access to write to memory.

I know that it can only be done on jailbroken devices.

I was asking how it was done or if there was a tutorial. I cant seem to find anything other than method hooking

Sorry, I was just making sure

In order to create a menu, you’ll need Shmoo’s public Mod Menu posted in tools.

However, since this one crashes on iOS 11-12 with offset patching dues substrate update, you’ll need to use MSHookMemory to patch offsets (search on iOSGods) — this only works on iOS 11-12.

Shmoo’s menu uses writeData, so you gotta change that up if you’re on iOS 11/12
