Help/Support Arm headers

[ProNab 728 iPhone 3G 1.0.0]

In ida how do u know which arm header to hack? Sometimes there are so many that i get confused on which one is the right one. Is this where gdb helps???

 

Also here: https://iosgods.com/topic/852-tutorial-how-to-hack-using-ida/, it is mentioned that "99% of the time those will be the only headers you'll use when hacking" if so should i just ignore the others?

Forget about that

You have to change from the top means from push change push to mov r0,r7

And change mov r4, r7 to BX LR

 

MOV R0, R7- 381C OR 0700A0E1

BX LR- 7047 OR 1EFF2FE1.

Sometimes using your logic helps too

 

Look at the class first, does it match where the function is headed

 

getMoney inside CarPhysics is not what you might be looking for lel

 

also for the function above, it says SET so try looking for STR instruction inside the function and hack that
