Default wireless network monitor mode on i9100

Hello,I followed instructions from, but after command sh at the end appears insmod: init_module 'dhd.ko' failed (Exec format error).
I have read that it should be a wrong compilation of dhd.ko file for kernel used, but unfortunately am not an expert.
Has anyone solved the problem?
