All you have to do is

 

MOV R0, #0 0x0020
BX LR 0x7047

Because what that is telling the GetPrice function to do is to just move zero into R0 (price) and then be done with the function.

no, in GDB you attach Kill Shot. So when ssh'ed into your phone:

gdb
<enter>
at nameofbinhere
<enter>
b *0x1f6d50 //start of the get price function
<enter>
c
<enter>

Then buy something. If your phone freezes when you buy something that means you have the right one but if not you don't.
