i am on lightweight kernel right now . i wanted to try this kernel. how do i assure myself that i will get a clean install.

should i simply flash this kernel over that ? or should i need to flash the rom again and then flash this kernel ?

i dont want any kernel conflicts

i am on prism rom v16
[Galaxy S 4 i9500 Android Development] *Exynos*:
The sound of this kernel is not very, very quiet, and settings through the synapse does not help, and the sound becomes Khripkov the feeling that the speaker was covered:(

Hello friends,

I am running Prism Bare bone V16 at the moment and want to play a bit with undervolting and governors.

If I am not satisfied with this kernel and want to revert to stock kernel, how can I do that?

Flashable zip for recovery would be preferred. If somebody could provide a link for download, that would be perfect. Thank you in advance.
[Galaxy S 4 i9500 Android Development] mor_1228:
u didnt made a backup before flashing this kernel ? i made a backup so i returned to it.
[Galaxy S 4 i9500 Android Development] body150165:
I didn't flash this kernel yet. I know that I can get back with a complete Nandroid restore. But I assume that it will take a bit longer to find out if I am happy with it. Just flashing the original kernel via recovery would be the easier way. Or can I restore the original kernel from a Nandroid backup using TWRP? Which partition is it?
[Galaxy S 4 i9500 Android Development] mor_1228:
my suggestion is restoring whole backup is safe and clean process.
