Help/Support Offset from LLDB

[Ted2 39k iPhone 13 Pro 16.0 Donor]

Hi,

I was trying to see if I could hack a game with ammo in it, since I've never played games like this lol

 

So I used lldb to set watchpoints from iGG adress, got a ida offset & removed aslr from it.

 

Then I loaded it in IDA, got the same instructions as lldb gave me, but for me it doesn't seem usefull at all.

 

1. It is a loc_.....

2. The sub_x function is long as hell & only used once

 

The loc_ function is this:

 

loc_1526D0                              ; CODE XREF: sub_150320+26F8�j

__text:00152748                 VSTR            S0, [R0,#0xA8]

 

I suppose for hacking ammo I need a LDR, STR or a SUB right? 

 

The function just looks strange to me, but maybe it is good one..

 

Anyone knows if this can be a usefull function at all?

Did you remove the ASLR from the binary BEFORE using IGG to find the offset?
