For some testing purposes I need to use the stock kernel. Is there any way I can flash stock kernel image without flashing the whole ROM? AFAIK the file boot.img under stock ROM is the stock kernel, so can I flash that via ADB? Currently on Faux's kernel.

Use fast boot to flash it . Fastboot flash boot boot.img.

Just to let you know, I've flashed backups in recovery to do the same

Yeah, this did the job. Went back to stock kernel successfully, however the WiFi would never turn on after flashing, no idea why! Came back to Faux and WiFi is back

If you're on a custom stock rom,, flash the rom zip again without wiping.

I am on full stock mate. It's all right though, the testings I was thinking of doing are done with stock kernel, and now I can stay on Faux's.

You have to flash the system.img too along with the boot.img . Remember this for future ref
