because it randomizes the offsets so what you think you are hacking could be completely differenthttp://iosgods.com/topic/687-tool-remove-aslr-v200/

  

no why?show mem

  

you don't patch aslr? O.o

  

so basically nothing useful :rofl:

  

For me:

1. It takes off the arm64 portion of the binary cos its useless to me

2. It makes it so that I can patch syscall (debugging protection) successfully

3. It makes it so that I can remove ASLR (address space layout randomization, basically makes it so that the original offset is hidden)

4. It makes it so that I'm able to set watchpoints and so that there are no 64 bit memory addresses

5. It makes it so that I can attach GDB to the app successfully (for breakpoints)

6. It makes it so that LLDB won't flip out when I try to attach

7. It makes it so that I don't have to patch the arm64 part as well as the armv7 part

8. Smaller binary size = less time to load in IDA

For you:

1. It makes the hack work

:p

I'm completely lost in this conversation O.o +_+

2. Go into MobileTerminal, switch to root, and run clutch. Then crack the binary and go to /var/mobile/Documents/Cracked. There should be a new .ipa file there. Just change the extension to .zip and unzip it.

3. Take the unzipped binary and put it in /var/mobile.

 

how can i do this
