Each rom has its own kernel so dont fear you do not have to manually change anything yourself. Just update the rom.
Going from 2.2 to 2.3 I would do a clean wipe and not just cache and davlik. Do a search for Caulkins format all which would be very helpful when going from Froyo to Gingerbread. It will give you a clean slate to start with
Please note Caulkins format all is a zip file that wipes all data on your phone. Then you can install any rom you want and usually has less issues. Also you may have GPS issues when going from 2.2 to 2.3. Try and read up on this stuff prior to flashing so you know what your getting yourself into..

^^^^ He is right. Every ROM has a kernal already. Untill you learn more about switching them I wouldn do it yet, you could break or brick something.

Ok, well if I switch my Rom will the kernel change automatically?

Yes, a new kernel is bundled with the ROM

Correct me if I'm wrong, but at this point I don't even think there are any custom kernels to install on 2.3 until the source code is released (if ever)...

Dont take this the wrong way but if you are unsure if a kernel comes with a rom I suggest you do a lot of reading up before flashing. Custom kernels are just that custom and flashed separately. Also certain kernels are for sense and different ones are for AOSP. Please try and understand that first before just flashing away. Asking questions may or may not be the way to go up in here.
I SUggest reading the stickies and threads done by people like toastch, caulkins xhausx and others similar to them. They have experience and a good track record as far as I am concerned

You are correct. There are, however, kernels with a few tweaks if I remember correctly, fixing Wi-Fi and maybe another issue (4G I think, not sure)

[Q] Help with Sense to ASOP ROM

I have searched the XDA site and the internet and I cannot find an answer. I am a newbie and I have been trying to find an answer for the last 3 days. Here is what I am trying to do:
I am looking to install a rooted Sense ROM on my Sprint HTC EVO. The phone is already rooted and I am running CM7. My question is, can I just flash a sense ROM coming from a AOSP ROM like CM7 or is there a different way I have to put a sense ROM on the phone?
Second part to my question: Do you reccomend a particular (Rooted)sense ROM?
Thanks in advance.

No different way..Just wipe data and cache. I'm using Eternal Prophecy and I like it...good battery life.
Yes. You can flash it just like any other rom Just put the zip on your sd card and go into recovery. Be sure to wipe everything. Even 2 or 3 times. I can't link it because im mobile but search for the vr superwipe. If coming from an aosp like you are you may have to apply the gps fix to get it working again. And as far as recommendations, I would go for Myn's twopointtwo or Koni's Elite III. If you want the look of stock without all the bloatware go for the Sprint lovers rom.

You probably didn't find a straight answer because you don't need to do anything special to flash from an AOSP ROM to a Sense ROM. Make a nandroid backup, wipe everything, and flash away.
Now your question about which Sense ROM to flash, I'm sure there's plenty of threads on that. The most stable Sense ROMs are still Froyo (2.2) w/Sense 1.0. But there's plenty of Gingerbread w/Sense 2.0 or 3.0 alphas and betas. If you don't want to be a tester I wouldn't mess with them. Just go to the Devolopment forum and pick a ROM with the most replies and most recent revision. That's how I started. That way you know you have an active developer and userbase.

[Q] Noob Question lol

What is a kernal and what does it do? Is it any different than a ROM? And how do you flash/install a kernal. I've flashed a few roms on the past few phones but I still have no idea what a kernal does.....any help appriciated..
You install a kernal simply by wiping caches,(cache and dalvik cache). Custom kernals allow you to do things a stock kernal wouldnt allow. There are some great developers of kernals here on XDA. You really just need to Search the forums for all of your answers, even google it. Once you do learn what a kernal is,you will be able to enjoy the full, or almost full, potential of your phone. Good luck!!
In a nutshell a kernel is the "heart" of the OS. It's really simple to flash. You start by making a nandroid that way if something goes wrong you have a backup, then wipe cache/dalvik 2x each, after that you can flash the kernel. It's a rinse and repeat process.

Quick question. I see that they are labeled like [sense] and [AOSP]. If I'm running MUIU as my rom right now, would I use an AOSP Kernel or does that matter.

Definitely matters. You need an AOSP kernel like Tiamat or Savaged Zen. I had good luck with Tiamat, but I'm running the stock kernel at the moment.

It wouldn't be a good idea to you a Sense kernel on anything besides a Sense ROM, or you will get a boot failure. I believe that MIUI use AOSP kernels.

[Q] ICS

What ROM is able to be a daily driver with the defy for T-Mobile?
BUMP........
Can someone please just tell me what ROM is a stable driver for ICS on the regular TMO Defy?

I've read parts of each thread but there is no thread with a sum of all the roms and up to date info. It is impossible to read through 1000 pages to determine which rom is usable. Why can't someone just help someone out?

Why can't you just wait to let the devs finish their work? All ROMS are kind of pre-alpha status, so if you want to have a reliable phone, stick with your stock software. Elsewise try experimenting and find the ROM fulfilling your needs!
PRE-ALPHA? I didn't know they were all Pre-Alpha. Which one is the closest to daily driver but doesn't have every bell and whistle? I have a Defy as a secondary phone and want to give ICS a whirl.
Thanks

From my own experience I can recommend Epsylons' build from 19-March

Ok and then is anything else necessary to get it working, IE new kernel, etc.?
Epsylon3's build from 19.03 is for the Froyo Kernel. You can use this kernel only with the Defy (green and red lens), not with Defy+. For Defy+ you need a build for the GB kernel (the latest being the one from 18.03 by quarx).
So, if you have a Defy and you're on the Froyo kernel and CM7 you can simply flash the 19.03 ICS build after wiping data, cache and Dalvik cache (and after flashing ICS wipe cache and Dalvik cache again). You'll also need to flash the new ICS gapps.
I assume you are familiar with rooting, 2ndInint, CWM and so on?! If not follow this thread: http://forum.xda-developers.com/showthread.php?t=1216982
Otherwise you should start over with this:
Flash a fixed sbf with Froyo from here: http://forum.xda-developers.com/showthread.php?t=966537.
Install CM7 (latest stable) from here: http://forum.xda-developers.com/showthread.php?t=1553782
And afterwards CM9 from here: http://defy-cm.net/defy-cm9-nightly/
And don't even think of porting all your apps with Titanium to CM9 - this can give you lots of trouble. Just make a clean install. If you have any trouble just use the forums' search function 99% of the questions you may want to ask, have been asked and answered already. Don't be lazy
Read the threads next time 90% of them tell you the state in the 1st post, if you would read them you would know, why ask the same question a hundred times, it clogs the forum

Need help picking a ROM / kernel

I've rooted my HTC Evo 4G (not LTE). I tried to set up a swap partition and learned that i need a different kernel. Regardless of whether or not i use swap memory, I'd still like to find a good ROM/Kernel. I'd love ICS, but they all say that 4g and the camera doesn't work yet. I have trouble finding the most up to date information. Recommendations on ROMS / Kernels / combinations?

That's akin to asking what car with what engine is the best. You'll get 100's of different answers, so here's mine
Decks Reloaded v.44 with Mason .15 kernel...see my sig.
Veyka will close this thread soon... No doubt about it. Just flash them all and see what YOU like best!

Okay, I found the kernel ... now I need to find the rom, right? because if I flash the kernel into the stock rom it will freak out ... so it's just a matter of executing two zips from recovery, the rom then the kernel? or am i forgetting something?

As long as the kernel matches the stock rom you can use it. It needs to be a git gingerbread sense kernel of you are on 2.3.3 or 2.3.5 stock if you're on 2.2 stock needs to be a froyo kernel. If you go to something like cm7 or decks reloaded, anything aosp based make sure you use an aosp gingerbread kernel. If you try ics and want a custom kernel or jb make sure to use matching kernels or you'll end up in a bootloop and need to reflash the rom to fix the kernel
Edit: when flashing make sure to do the proper wipes. For a rom wipe everything but the SD card, for a kernel or a modification wipe only cache and dalvik cache. When flashing a rom and a kernel at the same time, wipe everything but SD for rom then wipe.cache and dalvik and flash the kernel

Yes cm7.2 is a rom, I always used tiamat 4.1.0 on cm7.2. The kernel will add different governors, clockspeeds for overclocking, change the scheduler and allow for undervolting. The kernel is what allows the rom to talk to the hardware and vice versa, it contains all of the drivers for the hardware.

[Q] Kernel Question

Hey guys I want to make sure I'm safe when switching from rom to rom, and I am just confused about kernels. I understand that different kernels pertain to certain roms (AOSP, CM, TW, etc..), but what I don't understand is do all roms contain kernels? So will I always be safe switching from one rom to another, or do I need to make sure the roms come with the required kernel and how? So confused .
Thanks for the help.

AOSP has its own kernel and will most likely come with a kernel when you flash a AOSP ROM that goes for CM also. If you are just jumping from one TW to one TW rom you can just use the STOCK kernel. I know the JEDI ROM comes with its own SABER kernel and PERSEUS you have to flash yourself. Both these kernels are TW kernels so do not flash it to a AOSP kernel. This will result in a boot loop.
Thanks! Def appreciated. I was looking at Jelly beer and it said in the OP, make sure you have the correct recovery/kernel so I don't really know where you're supposed to get the CM kernel from. Ill just make sure to read carefully, and always ask first i guess.
Flashing PA 3.1 now, wish me luck!!!

haha yeaaa just read through everything. I have converted to TRWP recovery.
but PA 3.1 should be nice! I use alot of the samsung apps so I keep to the TW roms
I'm having great results with Vanilla RootBox and the SoapKernel
Hey and always just do a backup. That way doesn't matter what happens you can always restore.
