Help/Support Code injection

[ProNab 728 iPhone 3G 1.0.0]

In code injection we basically just have to know the offset and the hex for what we want the arm header to be changed to right?

For example i want to change this: XXXX SUB r1,r2,#1 to XXXX NOP

 

so i write the offset(xxxx) and the hex for nop right?

Yes. Check if the hex address of the function has 4 pairs of addresses or 2. If 2 use C046. If 4 use C046C046
