Your compiled module is not thus signed, so init_module failed (though arguably the return code could have been better - exec format error usually means the ELF is malformed, which it technically isn't). Check the modules that came with the S4 (/system/lib/modules or /vendor/lib/modules) with mod info (on Linux), and you'll see the ELF section with the signature. This is a feature that mainstream Linux has also added, in 3.7. share|improve this answer answered May 22 '13 at 20:40 Technologeeks 3,6061319 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name
