I want to modify android app writen on c++.
It stores its code mostly in .so file. The code is compiled for arm architecture.
When I open it in IDA it says that it can only read but modify.
But I need to inject one arm command. How can I do this?

With regard to your file-system, are you sure you have write-access to the file? – Jason Geffner Aug 19 '15 at 22:23

@JasonGeffner yes. It looked like ida pro doesn't support modyfing arm .so – kandi Aug 19 '15 at 22:25

Eresi is an option. Also there is hteditor which is capable I believe. And more recently the radare project – gandolf Aug 19 '15 at 23:15

You can modify the .so, it's just that IDA doesn't assemble ARM commands. You can use gnu as and objdump to translate your assembly to hex, then hex edit your .so, as detailed in this answer. – Guntram Blohm Aug 20 '15 at 07:12
