Help/Support GDB help needed

[El Antrax 0 10]

I'm having a problem with gdb. I keep running into Segmentation fault: 11. I have the app running, I cracked and thinned the binary, replaced the old one with the cracked. Not sure what to do anymore, any help is appreciated . Oh i'm trying to hack Kendall And Kylie

i know why but i can't find the post segmentation fault usually mean anti debug trick there is a tutorial on how to remove it but i can't find it sorry

I tried that but mine didn't have the _syscall. I also tried looking for other ones that dida had mention on another post but it only had one string/import thing

Make a project in theos, bundle id is com.apple.UIKit

 

Tweak.xm code:

#import <substrate.h>

#if !defined(PT_DENY_ATTACH)
#define PT_DENY_ATTACH 31
#endif

#if !defined(sys_ptrace_request)
#define sys_ptrace_request 26
#endif

static int (*_ptraceHook)(int request, pid_t pid, caddr_t addr, int data);
static int (*_syscall)(long request, long pid, long addr, long data);

static int $ptraceHook(int request, pid_t pid, caddr_t addr, int data) {
        if (request == PT_DENY_ATTACH) {
                request = -1;
        }
        return _ptraceHook(request,pid,addr,data);
}

static int $syscall(long request, long pid, long addr, long data) {
        if (request == sys_ptrace_request) {
                return 0;
        }
        return _syscall(request,pid,addr,data);
}

%ctor {
        MSHookFunction((void *)MSFindSymbol(NULL,"_ptrace"), (void *)$ptraceHook, (void **)&_ptraceHook);
        MSHookFunction((void *)MSFindSymbol(NULL,"_syscall"),(void *)$syscall,(void **)&_syscall);
}

This code isn't mine. it's sharedRoutine's. I take no credit for it but I hate macros

I'll install theos and try this thanks
