I'm thinking about flashing the "Flash" kernel with TWRP. Can a kernel be flashed at any time or is it better to do as part of a clean build?

So I've been flashing various roms, kernels, and radios onto my Nexus S since the release. I've never read to deeply into the exact procedure for flashing these items.
I know you are suppose to wipe device, cache, davik, ect. But then are you suppose to flash the rom, reboot the device, and then flash the kernel and radio?
What if you wiped the device and just flashed a rom without a kernel? Does the kernel you have previously take into effect or is it built into the rom?
No, Roms come with a kernel. If you don't flash a kernel you will have whatever kernel the developer uses in his/her Rom.

Wha? Not all ROM's come with kernels... if you flash one that does not have a kernel then you will be left with what you had before (stock).
Is it possible for me just to flash stock kernel instead of the whole stock Rom ? If so is it available here ?

extract the boot.img from a stock rom and flash it via the terminal emulator app or via fastboot. theres always the chance that the stock kernel wont run on whatever rom that youre using. if so, just reflash the rom.
I've got a link to a stock kernel somewhere, which you can flash via cwm recovery. I'll see if i can dig it up.

So I lost my phone, got a new one, rooted using the casual root/unlock w/twrp method found on this forum http://forum.xda-developers.com/show....php?t=2332825
Is it possible to somehow improperly root/unlock without bricking? Or that I just got a bad download. I am having random reboots with just about every kernel I flash, some worse than others. I can only run the stock kernel. Running a clean 2.9 and the latest TWRP. Would it be useful to do a full wipe and "reroot/unlock"
What rom are you using and what kernels are you trying to flash?

Right, sorry. Liquid 2.9..tried flashing multiple builds of BMS, a few lk builds, dkp, and team kernalizer kernel. I think that's all of the available kernels for the s3

Clean flashes, freshly installed rom after first boot with the stock kernel, I reboot and flash the new kernel and just never fee stability.

Well, I follow AOSP kernel development a little bit. If I were you, I'd start by flashing a kernel built within seven days of July 20th cuz it seems every two to three weeks, kernel commits render older roms useless. If you don't follow AOSP commits in the more popular rom or kernel threads then I suggest staying away from custom kernels cuz they move quickly. Custom AOSP kernels built on 8/13 won't work on older roms for example.
Edit: I got July 20th cuz LiquidSmooth was last updated on July 20th btw. Just to be clear.
Good advice. I don't follow the aosp commits but I did have the same thought and flashed an older version of BMS (I really want to give it some burn) didn't work... I'll try an older build of lk too just to see where I am.
Really hoping 4.3 somehow resolves this issue for me.
Thanks for your help.

Hope so too. I'm trying out Slim Bean beta 2 with BMS kernel from 8/15 and it's working great performance wise. I'd even suggest trying newer 4.3 rooms (CM, Unofficial CM, PA, etc) just for a couple hours and trying your hand with a custom kernel from 8/13 or newer. Or trying a newer 4.2.2 nightly with a custom kernel. For BMS, I believe GideonX said that 7/30 is the last JB 4.2.2 kernel he's made.
How long would you say you waited before flashing the kernel? I usually flash rom, reinstall my apps, set up home screens, then flash a kernel. Maybe 20 minutes between rom and kernel flash cuz of habit.

I'm using catacylsm rom+franco kernel
If I want to flash another rom, do I need to flash back to catacylsm's kernel and flash the new rom?
Thanks!
Hi,
No, no need to flash back the stock kernel before (or the one from Cataclysm rom). Since you'll flash another rom you do a full wipe (clean flash), it will be enough.

Atm i have elementalx kernel installed and thinking about switching to franco when i install a new rom. I am on stock rom and will probably flash to Slimkat, will i just have to flash Rom + google apps and then elementalx/franco?
Read the op for slim. If it says to flash gapps then you'll need to do that. Then flash the kernel
