[Q] (Q) How to recover kernel from a ROM - Nexus S Q&A, Help & Troubleshooting

I have really taken a liking to the kernel that comes with the CM Kang's here
I personally have been getting really good battery life while on that ROM/kernel
I was wondering if there is a way to "extract" or recover the kernel from that ROM so I could make it a separate, flashable zip if I switch ROMs. Thanks!

[Q] How to obtain n install stock kernel onto a custom ROM?

oooo okay so basically so far everyone is looking for ways to install a custom kernel onto stock rom, I'm the opposite. I have read about it being done before but what exactly is the procedure?
right now I have the stock kernel in the format of a .RAR, within the archive lies quite a number of files i.e. sound, kernel..
currently am using a CSL Mi-410 (FIH-FB0, OEM for Motorola Triumph, Ideos X6..) on tj_style's RC2.. trying to get the stock gingerbread kernel on it cuz apparently its bit more stable than the OC-ed custom kernel.
any advice would be greatly appreciated! Thanks!

[Q] Gingerbread and new kernels

Is it safe to install a new kernel (like matr1x 19.0) that's based on ICS on a gingerbread ROM like CM7?
I am asking because my friend's Nexus S is limited to the current ROM because it was given to her for free for a sociology study, so it's recording data. I'm looking to install a new kernel for overclocking, BLN, and so forth.
Thanks.
Is this a serious question?
No. It won't boot. Just leave it alone if it's a work phone. When the study is over you can put franco's old gb kernel on it.

[POLL] Kernel Knowledge

I am experienced with rooting and flashing Roms, but I have never flashed a Kernel. I know how to and I know why I would need/want to. I am just wondering what I need to do if I decide to flash a different Rom or even return to stock Rom. Example: If I flash a Kernel while running The Executioner 3 Rom for my rooted Verizon Samsung Galaxy S III, would I need to restore that Rom's original Kernel before flashing a different custom or stock Rom?
Re: [Q] Kernel Knowledge
Depends on the kernel.
Check kernel thread.
But I doubt you will have any problems

So pretty much I would just be able to wipe data and cache and flash new rom as usual?

Nah when you flash a new rom, it flashes its own packaged kernel as well. If you flash a newer version of that rom, say Executioner 3.5 was released, it would also flash its own kernel so you would need to reflash your other custom kernel if you wanted that back. If you're moving between different roms, you wipe and clear away all of the previous mods/kernels/etc that you flashed from your prior rom.
Questions and help go in Q&A
I changed the title to reflect a POLL rather than question
FNM
what i do is set up rom to my liking, make a nandroid, then flash kernel, if i dont like the kernel i go back back to my nandroid.
Thank you all for the great answers.

[Q] Kernels and Custom ROMs

I am wondering how Kernel and ROM compatibility work, in simple terms. How do I know if a Kernel will work with a custom ROM?
For example, I was on a rom which came with M-Kernel, lean kernel, and stock kernel as options. I also am using Franco kernel on my phone. I've just flashed a new rom that did not have a kernel choice. How would I know if could use M-Kernel (or any kernel for that matter) with this ROM?
I know sometimes ROMs will list what kernels are recommended and some kernel pages will recommend roms, but what if they don't? Can any kernel work on any rom?
Thank you!
Each kernel thread will list what type of ROM they work on, AOKP, AOSP, Stock etc.
You can't always use any kernel you need to check the thread.
I'm actualy on AndroidParanoid 4+ Beta2 by Nims11 (i9100), Not the best perfomance, but this is still beta phase. And I'm litle confuse about kernel. Which one is the best option for this ROM? Any experience. Thanks.

Custom Kernel

I'm thinking of installing a custom kernel (elementalX) but I'm not interested in overclocking it or anything like that, so I'd be running it on vanilla settings. My question is that is there any point in flashing a custom kernel in this case? Will I benefit from installing it (maybe the phone will run a bit smoother, better battery life, etc) or will I just be creating more potential issues?
Currently running LibertyROM (4.4.2 KitKat, Sense 6) with whatever kernel it came with.
bump!
oh c'mon. is it really that stupid of a question?
