"If you are on a stock-like 4.1.2 ROM that does not rely on a modified ramdisk (CM10, AOKP, etc.), flash one of the following zips and reboot before installing this kernel for the first time.

Stock 4.1.2 kernel with Init.d support and insecure adb thanks to Faux123 - http://goo.im/devs/Metallice/Nexus7/...nitD_4.1.2.zip"
Maybe it is a language barrier, but your statement reads to me as in if you are running AOKP or CM10,u NEED TO flash one of the stock kernels and reboot before u flash your modified version. That is what I did. Flashed one of the stock kernels u linked and that did not boot up. Flashed your modified one to see if that would boot, and that didnt either.
If you're running stock 4.1.2 or a ROM that doesn't include init.d support, then you should flash the stock with init.d support zip before flashing the motley kernel to give yourself init.d support. If you're running something like aokp or cm10, it requires it's own special ramdisk, and the one cm currently provides isn't proper.
