[Q] Kernel Questions - Nexus S Q&A, Help & Troubleshooting

Guys i have two question..Whats the difference between All other ROMs and Custom IO control (CM tweak)
links from https://docs.google.com/spreadsheet/ccc?key=0AntDDKv-lS6IdEt6NWVkX01vNmpfbEh4MHo4eDRCbXc#gid=0
And the second one is to flash the kernel i must first flash kernel and then the rom or first the rom and then the kernel??Thnx

Cm tweak is for cm based ROMs, all others is for, well, all others. Flash kernel after flashing ROM.

How i will find which roms are CM based?

Read the thread about the ROM you are interested in. If I'm not familiar with a ROM, i generally read the first page and the last few pages. That way I see what the dev says about it, and see more recent reviews/comments about the current version

[Q] [i9020-T] Trinity UV Kernel Flashing

Hey everyone I'm kinda new to the whole kernel flashing business and I'm trying to flash the UV Trinity kernel to my Nexus S. From what I've read I only need to flash the zip from recovery without having to do any sort of wiping. The main problem when I tried this is that the phone went into a boot loop and wouldn't go past the boot animation for the kernel. I'm not sure if it's because the kernel is based off of 2.3.4 and I'm currently running CM-7.0.3. Morfic's thread indicated that the kernel was made for CM7 so I don't know what's going wrong here.

You have a ROM based on 2.3.3, meaning it's not compatible with a kernel made for 2.3.4.
Try flashing the latest cm7 and then the kernel.

Would it work if I tried a CM7 variant that's based off of the 2.3.4 source? I'm going for a stable phone and unsure about the nightly builds at this point. If not I'll probably just wait CM to update and release the rom.

it should work on any 2.3.4 cm based roms.

[Q] Custom Kernel

Hi my skyrocket is currently running 4.0.3 ics leaked rom, and I was wondering if i could flash custom kernel on ics rom, or would I have to stock gingerbread to use custom kernel. I just do not want to get bricked etc. Thank you.
It depends on the ROM, if it's SKY ICS or some other modded Samsung rom, then you pretty much have to stick with stock, or do some research because I don't really know what Kernels are available for it. Maybe someone with more knowledge will chime in...
If it's AOSP based (CM9, AOKP, Chimaira, etc), then the only other option I know of is InstigatorX's kernel, which seems to work quite well. Pick a stable version, since the latest has issues with the camera. The stock kernel for CM9 is also quite good, but the CPU governors added in Instigators are great for saving battery.

You can flash cymbaline. Don't try to flash instigator's cm9 kernal you aren't using an aosp rom. Cymbaline fits your deal nicely. You'll dig it.

Other Kernels for [ROM][ICS][IMM76L] CyanogenMod 9 by ivendor - beta 2 ( I9001 )

Hello, i have downloaded and flashed my I9001 with [ROM][ICS][IMM76L] CyanogenMod 9 by ivendor - beta 2. I have a question about that rom. Can other kernels be installed using that Rom so that it can be overclocked and thus resulting in more performance. Im asking that because that Rom is quite perfect( ignoring the camera problem which after 5 pic gets jammed!). It would be nice if other kernels could be used. Im looking foward to know about it. Thanks in advance and cheers

You shouldn't use that kernel, it's very outdated. The only ICS kernel that is updated frequently is the CastagnaIT Kernel. I would recommend to use that one if you want OC/UV support

Custom Kernel

I have downloaded CM 10 from get.cm and installed it on my galaxy tab 2, and flashed it through recovery. Does flashing the ROM means I am using CM kernel or I have to download the kernel and flash it manually?

You will be using the CM kernel

Besides the CM kernel, are there any other kernels who offer a smoother transition to the higher CPU speeds or more governors?
You will use CM kernel. Coz they are only match with CM ROM .

[Q] Cyanogenmod: Safe to flash a Kernel...?

Hi everyone,
I know this is probably a really nooby question, but im running the most recent nightly of cyanogenmod and i noticed it has its own kernel under About Phone. I would like to use faux kernel instead. Is it safe to flash faux kernel over the top of it or will it mess things up? Thanks guys!
All ROMs have kernels. They can't work without one so this makes the rules of changing kernels with cm no different from any other Rom.
You're right though, it's a really nooby question. I'm not trying to offend but not knowing this means you're not ready for flashing kernels. Please read the sticky threads in Q&A and general to bump your knowledge up to the next level first
Fyi, cm use CAF kernels only so you can only Flash CAF kernels.

you can flash any kernel you want.. but it doesnt mean that itll run. cyanogenmod uses caf for source, the moved away from aosp. so you can flash and run kernels based in caf, not aosp. faux kernel is an aosp kernel, so if you flash it you wont boot up.
Yeah, but only flash kernels for the n5. Flashing something else can brick it. If it's a caf based rom flash a caf kernel.

Ive read the stickies. I wanted to be cautious because im new to cyanogen and i didnt wanna mess anything up. I was using Cataclysm with Faux so I didnt need to know about CAF kernels back then. Thanks for your help anyway
