002B2CB2  |.>71AAF64A              |movw r1, #0xafaa                                 From 0x002B2CA4
002B2CB6  |. 4F8F1A7               |sub.w r4, r7, #0xf8
002B2CBA  |. 1ABF2C0               |movt r1, #0xab
002B2CBE  |. 9807                  |ldr r0, [sp, #0x1c]
002B2CC0  |. 4479                  |add r1, pc
002B2CC2  |. 6942                  |ldr r2, [r0, #0x14]
002B2CC4  |. 4620                  |mov r0, r4
002B2CC6  |. C824F250              |blx ._sprintf

 

 

002B2CC2  |. 6942                  |ldr r2, [r0, #0x14] ----- r2 is the required level  to locked the level , i try this :

 

 

1. register write  r2 1 to change the required level from 55 to 1 i see the change in lldb but if a run with c continue, nothing are changed

 

What is wrong ?

If there are no effects on the game that means its the wrong offset... Did you remove ASLR from the game?
