Hello everyone,

I have a tweak that patches some memory in an app. On my iPhone 7 with iOS 14 and checkra1n it works perfectly. The code looks like this

void (*_mySymbol)();
	MSHookSymbol(_mySymbol ,"_mySymbol",NULL);
	const uint8_t data[] = {
		0x1,0x0,0x0,0x0
	};
	

	kern_return_t err = KERN_SUCCESS;
	mach_port_t port = mach_task_self();
	vm_address_t address = (uintptr_t) _mySymbol;
	err = vm_protect(port,(vm_address_t)address, sizeof(data),false,VM_PROT_READ | VM_PROT_WRITE | VM_PROT_COPY);

	if (err != KERN_SUCCESS)
	{
		NSLog(@"false");
		return;
	}
	err = vm_write(port,address,(vm_address_t) &data,sizeof(data));

When I now want to run this tweak on my A12 device (with unc0ver), MSHookSymbol just returns an address that is out of region. So I guess I have to calculate a different offset, but I don't really know what I'm missing and what I should do. Anyone knows what I have to do differently here for the A12 device?

Thx

thanks

Thanks

Also looking for this, especially for the main course. The old hack unfortunately only works for the old course 

Thanks

Probably your version mismatch with the hack version

I don’t think I’m gonna update this since it not popular enough to update, cuz updating this take a lot of time

I do have the right version 5.2.6 installed though. Everything works great except for the the main course, that still requires Premium.

The "Main Course" is only available when setting to learn from English. Then after a few lessons it requires Premium. 

All lessons before also have a speaking chapter that also requires Premium. 

I made a video showing what I mean

Name of the game you want hacked: Du Chinese – Mandarin Study
Version of the game: 1.10.0
iTunes Link for the app: https://apps.apple.com/us/app/du-chinese-mandarin-reading/id1052961520
Jailbroken or Non-Jailbroken: Jailbroken

Requested Features:

Access to all premium lessons

Can you make it work with the Main Course of the app?

Right it just works with the immersive lessons which is very nice but the Main course has a lot more material to learn from and requires premium. 

Because they don't bypass the jailbreak detection for this specific app

Ah too bad, but thank you!

Hey,

I want to decrypt an app iOS 12. The problem is the app has a jailbreak detection and crashes on launch. Therefore I can‘t use CrackerXI. Is there another way to decrypt the app ?

Let's see if it stil works

Nice

Thx

Thanks
