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.

Who is running OMGB 1.1.1? I am thinking about switching kernels and wonder what is compatible with that ROM? Also, how risky is it to switch kernels. People keep telling me you can ruin your phone.
Thanks!

Are you currently using the rom and if so, what is wrong with the default kernel?

Rooting can ruin your phone. A bad flash can ruin your phone. The good thing about flashing kernels and I've flash a lot of them, you usually can go back into recovery and flash another one if your device doesn't play well with a particular one.
I am currently running CM7 and. Kernel 2.6.37.4 cm. Looking to switch today

I hear ya. I'm itching to flash it right now, but my wife and one of my sons are enroute to Orlando and I don't want to flash a rom that I'm uncertain of in case I need to contact them or vice-versa. I haven't had a "home phone" in years. We all have smartphones..lol
I went ahead and flashed this rom and then added my 3rd party apps and I must say that i am impressed. It is stable and everything appears to work as it should. I did notice a bug where when you add a pattern lock, the default lock screen no longer displays, not even after a reboot. I just finished making a nandroid backup of it and will definitely use this rom. This is shweeeet!
You can flash an AOSP kernel. The SBC kernels can ruin your phone. I am using tiamat nonsbc aosp kernel with this rom.
Thanks for the info guys! I ended up flashing OMGB rom and like it so far. Do I flash that kernel over the rom then? Do I just find the kernel in one of these threads or is it on ROM Manager?
Thanks
Hello,
I'm a newbie and I'm running android 2.2, HTC stock kernel WITH mikfroyo V4.4. and I wanna change Roms preferably Evo Zone which runs gingerbread 2.3.3. Do I have to change the kernel and the Rom or just the Rom. Please help. thanks

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)
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.
Hey there, I'm still fairly new to the custom Android stuff and I had a question about ROMs that isn't too clear to me.
Let me start off by saying I have made a nandroid backup, and I have flashed ROMs before on my HTC One X, but I recently switched to the S III because I was unhappy with the < 200 MB of usable RAM.
I am currently looking into trying 2-3 ROMs, AOKP, TuchMi, and maybe CyanogenMod 10, mostly because I am unhappy with the stock battery life.
From what I have been able to gather, the kernels for AOKP and TouchWiz based ROMs are incompatible, and it is not recommended to mix them up.
Here are some of my basic questions:
1) TuchMi and AOKP come with kernels inide them, are they automatically installed when I flash the ROM?
1a) If they are not automatically installed, what happens if I mix up the ROM/kernel?
2) Does a nandroid backup also backup the Kernel?
stock kernels work great for me always

If they already come with kernals then they will be automatically installed when flashing them in CWM recovery.
On my previous phone nandroid backups did not back up the kernal but on the S3 it looks like it may be backing up the kernal as it does state that it is making a backup of the boot image. My old phone never did receive official cwm so maybe this was a feature they added later.
Remember when changing kernals to ALWAYS wipe cache/dalvik cache before using a new kernal.

Yes kernels usually come with aokp and cm 10. tuch uses stock. During nandroids I believe that the kernel is backed up. I have flashed different ROMs including aokp, and then applying ktoonsez kernel and then restoring back to stock rooted with nandroid. Mixing ROMs and kernels can get ugly... sometimes unsupported also. Just make sure you make nandroid backups.
Try aokp and then ktoonsez' kernel. Wicked combo.
Also, what carrier are you with?

I am with AT&T currently, I will try the AOKP -> ktoonsez kernel tomorrow . Part of me still wants to use TuchMi though for the battery life and I will miss some of the Sense apps... mostly the Phone app.
Ah OK. I am with ATT also. Let me know if you need any assistance. The aokp ROM and toonsez kernel should get very nice battery stats. Mine is doing pretty well.

I have a couple of newbie questions I Hope someone can answer. I'm rooted and using the pegasus kernal. I looked at the kernal page for my phone and saw that the Matrix Kernal was AOSP only. What does that mean? I was also wondering about modems. Is it safe to flash then with the stock rom, or do you need something else before flashing s modem. Thanks for any advise.

AOSP = Android Open Source Project. So matrix kernel will only work with roms that using AOSP. Example: Cyanogen Mod, Carbon Rom, Pac Man Rom...etc..
Its safe to flash modems using the stock rom. You can do it on AOSP as well.
Thank you
Thank you for your help.
