So, I have compiled a new android with deactivation of modules signature. CONFIG_MODULE_SIG is not set in the .config

And I built the lime.ko but when I try to install it, i have this error:
root@msm8916_64:/ # insmod /sdcard/lime.ko "path=tcp:4444 format=lime"
insmod: failed to load /sdcard/lime.ko: Exec format error

Why?!?
Anyone with an idea would be really nice....
Thanks

It sounds like EFI_SECURE_BOOT_SIG_ENFORCE kernel config has been enabled. That prevents from loading unsigned third party modules if UEFI Secure Boot is enabled.

The easiest way to fix this issue is to disable Secure Boot in UEFI (BIOS) settings.

Your second error seems like that your cross compiling environment isn't the same as the running kernel.

Were you able to get past this issue?

I got this because my kernel didn't have .ko support compiled in, and fixed it by recompiling my kernel with LKM support.
