Hi there!!

I'm about to unlock my phone bootloader, and i wanna know some things about kernels:
  1. Can i "downgrade" the kernel. For example from a KitKat kernel to Stock (Jelly Bean 4.1) Kernel?
  2. Can i use a KitKat Kernel in a Jelly Bean Rom?
  3. If Kernel have CWM recovery, it still working even if ROM stop working?

I know that in Linux you can update to the lastest kernel in same distro and don't matters, but Android is "special"...
Now i've CWM for locked bootloader and it is installed in ROM instead in Kernel, then if ROM is damaged CWM can stop working. I think if is included in Kernel then don't matters what happen in ROM, but I want to be sure.

Thanks!!

I'm not really sure about question 1 & 2.
Answer for question 3:
Yes, the recovery should work even the rom is messed up.
Thats when bootloop happen .

1- Each rom has a specific kernel so if you want to install a kitkat kernel you can't install a JB rom so if you want to downgrade you can only downgrade the version of the kernel !!!
2-As I mentioned above you can't
3-Yes because the kernel is not damaged in your case so CWM will be working with no issues !!!

If You are going to unlock Your bootloader in future, do remember to backup Your TA partition.
