  1. No problems. Can you tell me the name author so that i can contact him? Aren't all thumb instructions 16-bits? Please shade more light on this because i'm new to ARM architecture
  2. Actually 0x123 is some magic values upon which the library activates device specific functionality. So loading value in R1 is must. And as you told mov r0, #100 mul r0, r0 (multiply) Wont it take more than 2 bytes? I'm looking for some tuts/exps for code caving for ARM.
  3. Basically i want to replace MOVS R1, #0x0 with MOV.W R1, #0x123 .since later instruction requires 4 bytes it is impossible to simply replace in HEX code. P.S. I'm trying to hack android native library. I found most hacking tutorials here, so i'm asking this question here
