you can try toggling signiture verificaTION off,if there is such a setting,i cant remember off the top of my head. you could also try re-signing the file after you modify and rezip it. there are free signing utilities if you search.
id also give it as shot using CW instead of twrp,if all else fails.
you could also flash the kernel without modifiying it and see if it installs that way(make a nandroid first so you can get back to how you are)
you are absolutely right!
i just try to install original kernel, seems working!
but i did turn off signature, so how i can re-zip the folder?
