I want to fix a .plt segment in IDA Pro by replacing 12 bytes from start of every function in the .plt segment with the ones I specify.
I want to just make each function return so I'm replacing opcodes to do this, but doing this by hand is a painful job. My fingers and palm hurt after I modified a single library, so I need a way to do that with IDA Python.
It's an ARM 32 shared library, I know it doesn't matter here but specified for goodness sake.
This is the hex I'm replacing in every function:
00 00 a0 e1 00 00 a0 e3 1e ff 2f e1
This is what this hex is all about:
movs r0, r0 movs r0, #0 bx lr
