I am sure most of you are aware of this already but there are goodies for us starting to show up in Rom Manager. Makes downloading the Roms a lot easier.
There are also a few kernels available.
This is starting to get exciting!
Thanks to all the Devs for making this stuff available.
+1
jt1134 and Deodexed have their latest and greatest up there.
Among the fine kernels and roms released, you'll find rom insyalls of VZW visual VM, Extended Softkey Backlight, Disable BLN, and other goodies.
Many thanks to jt1134 and deodexed for making their stuff even easier to play with. (God help us all...)
I see two entries for kernels in jt1334's list;
"Stable Voodoo Kernel 11/02" and
"Stable Non-Voodoo Kernel 11/02"
Can anyone provide additional details on these 2 kernels? What they contain, etc?

They basically contain all the latest goodies with the exception of overclocking.
while in recovery it only goes halfway and then stops and says unable to verify whole signature any suggestions?

You need to use Clockworkmod recovery not stock recovery.

Hey anyone that's got some noob time, I was curious what exactly is a kernel, why are there different kernels, when to know if you need to use a different kernel and lastly instructions on how to flash a kernel. I am pretty experienced in dealing with my phone and I'm capable of bringing my phone back from ANY software brick with ODIN and I have been flashing ROMS for about 5 months. I recently was reading up on the Epic 4g forums because I was going to root my epic when I buy it and I noticed much more about kernels in the epic 4g forums. Any knowledge would be appreciated! Thanks!
Roms, Basebands and Kernels, a basic overview
The baseband is only the 'radio' part of the phone that makes the calls, the 3G and Wifi connections, GPS connections, etc. As you thought, it is totally separate from a ROM. Updating a ROM will not update a baseband and going back to an older ROM will not 'downgrade' the baseband either. Upgrades to a baseband my improve signal strength, call quality, maybe have software tweaks to improve battery life while on 3G/Wifi, etc - things like that.
Kernels are the core software code that allows CPU to over-clocking and controls voltage controls. Think of it like Bios settings on your computer (PC, that is)..that's really all they do. Now, a kernel can be completely separate from a ROM, but a new ROM contains a kernel in it so it will run. So, a kernel can be both separately applied from a ROM, but is also part of a ROM.
The ROM is basically everything else but the apps and the two things above. It's actually the OS, as well as any stock apps that come with it - and any new improvements, features, etc. The increasing build numbers reflect bug fixes, known issue solutions, feature improvements, etc...thing of them like windows service packs and/or any software update.
Some of the other phones modifying the kernel may be done more because the phone design and limitations
Hope that helps
Very helpful, I was sure to click thanks. I'm curious how to change the kernel on my phone and when should i consider changing it. Do I use ODIN to change the kernel? Also can any kernel work with any ROM? If not, how do I know which ROMs a specific kernel is compatible with?

Most kernels can be flashed just like a ROM, very few require ODIN and if it does the dev will specifically say so. Also not every kernel works with every ROM. However they are usually made to work with any ROM base don a version number. For example if a kernel is made for 2.2 than all ROMs that are made from 2.2 will work with it. The version number a kernel is meant to be used with is always in the OP of its thread.
And one last thing, if it is a kernel that has to be flashed via ODIN could someone give a step by step? I've got return to stock via ODIN memorized and I've done it plenty of times but not sure about the procedure for kernels.
Put the kernel in the PDA do not repartition, On a side note, when you are flashing things especially adding new kernels etc, It is better to go to recovery manually and do it from there. Sometimes the custom stuff or CWM have conflicts and it doesn't flash and you have to go odin back......... that's been my experience
so just use adb to get to stock recovery and then choose install packages? forgive me for my extreme detail

Have you been using 2.2.1 ROMs?? I always have to ODIN from 2.2.1 ROMs cause I can't wipe data from CWM on them. So when it gets to that part of flashing the ROM it freezes

Just wondering if anybody could populate a list of kernels that would work with this radio and rom that was just released. Currently on the stock kernel that comes with the Tbolt fresh out of the box, couldn't find any other threads (including the OP which this new stuff was released on) that listed specific kernels that were compatible. Thanks in advance for the help!
Sidenote: If the compatible kernels listed had links next to them providing the details and benefits/differences between each would also be helpful in my choosing one, thank you.
One last thing (sorry I'm a noob lol), is there any specific order required between the flashing of radios/roms/kernels? Like: Flash new Radio first, then Rom, then Kernel. Or are they pretty interchangeable as long as they are compatible? Again, thank you for your help.
Someone more experienced just informed me that all new Roms come with kernels in them! LOL I am such a nooblet sorry for the post. However, it would be nice to know which kernels are compatible in case someone wanted to switch kernels but use that Rom still.
All kernels for Sense will work... if you can, find the ones using anykernel updater so my RAMdisk stays intact.

After I rooted my phone, I simply installed Bionix 1.3 on it and that was it.
Do I NEED to install a kernel? What does that do exactly?
Everything has been running fine on my T-Mo Vibrant with the Bionix, but would the kernel help in any way?
Thanks.
Read the ROM OP. A kernel is usually prepackaged. Understand your ROM first, then start working with different kernels. Go to the Bible stickied in the forum and you'll see links to all the kernels.
Kernels come with all custom roms. With Bionix roms, they all come with a stock + Voodoo kernel. Its is a stock kernel that has the Voodoo lagfix built in and comes preactivated. Custom kernels have more tweaks and features than the stock voodoo kernels, like Voodoo sound, Overclocking and Undervolting abilities, and more. I advise you research the advantages and disadvantages of installing custom kernels. Until you have done your research about them, i suggest you stay on the stock+Voodoo kernel for now. Once you think you're ready for a custom kernel, please choose one that is up-to-date and was built to work on Froyo roms, like Bali, Bali-X, Bullet, and Immortality.
Okay, so my question then is, with the Bionix them, if I wanted to install Bali 1.8v
http://forum.xda-developers.com/showthread.php?t=1043947
Would I just do that via Clockwork Mod, then reinstall the Bionix ROM?
Or would that be too messy and possibly screw something up?
Thanks Mr. Apocalypse
You can flash kernels through CWR or SGS Kernel Flasher (in the market). Thing is, the I agree with Mr Apocalypse, you need to be reading and checking out things or your next post will be, "I bricked my phone, how to I fix it?"
This is directly from the OP of the Bionix ROM thread.
Optional Kernels:
NOTE:
Team Whiskey is not liable and takes absolutely no responsibility for any damages. Overclocking your phone adds additional stress to your hardware, so please understand the risks involved before you decide to overclock. Not all devices overclock the same, so please test the different clock speeds and see which one works best for you. Many times, certain devices will not accept an overclock at all. If you fall into this category, you will have to flash back to a stock kernel.
(all of these kernels have been compiled from official Vibrant 2.2 source code. They are include voodoo sound, voodoo color, and bln support. Bionix-v 1.3.1 already included the necessary apps for these features. Test these optional kernels and see which one works best for you!)

After you flash Bionix, then flash Bali. You can do that in ClockWorkMod Recovery or SGS Kernel Flasher, i prefer to use CWM Recovery because sometimes the app doesnt install some special files that are needed for things like BLN to work. But either way is ok, just dont reflash the rom afterward or you'll be back on the stock+Voodoo kernel
Bali is a great choice, drhonk builds those rock solid.
I'm not really sure I understand and maybe someone can help me to, but the appeal of CWM to me was the ability to flash a ROM without needing a PC. However, most of the ROM's in the dev section say that a kernel flash is required and the utility requires a PC. The appeal of being able to flash a new ROM at any time is lost since I need to wait until I'm at home with my PC. If a kernel flash at the PC is required for most ROM's then why CWM at that point?
I'm realizing as I write this that the answer is likely that it's easier for a noob than adb. I still ask the question in the event there is something else I'm missing.
Also, before I get 30 hypersensitive replies about not appreciating the devs work and I should dev something myself if I don't like it please know that this is not intended to criticize the work of the devs. I'd just like to know if there is something I'm missing or maybe that I'm misunderstanding that a kernel flash is required when I read the releases.

Yes! You missed this thread
All the latest roms are using Faux kernel anyways, Flash once, and then you can use CWM to flash any multiple roms you want
The ONLY time you NEED to flash a seperate kernel is when going to a totally different build. Examples:
Sense 3.0 to Sense 3.5
Sense 3.5 to Sense 3.0
ICS to Sense 3.0
ICS to Sense 3.5
Sense 3.0 to ICS
ICS to Sense 3.5
...etc
Other than that the kernel that you use is still pretty much stock.

This is true, but each successive release says that a kernel update is needed. I am assuming that this includes not only those freshly flashing the ROM, but also those flashing from a ROM's previous version. Are they incompatible from version to version? Basically, if I'm bored while out and wanted to flash a ROM then flash the kernel later are there risks?

This looks great! Since T-Mobile just throttled my data for the remainder of my billing cycle I will have to follow the thread and then give it a try later when I have WiFi. Thanks for the link.
Thanks Binary. That makes sense. No pun intended. So then the boot.img a dev includes with the packaged ROM is more or less a suggested kernel to best optimize their ROM and not that there are features of a ROM that will not work?

That depends on the kernel that the developer includes.
If it's a faux edition then there are a few tweaks however it's still stock.
All features should be accessable in the rom as long as you are using an unsecured kernel.
If I was to install, say, the Liquid Smooth ROM onto my i717 (I have a good amount of experience with flashing ROMs, so that much I know,) specifically, the KitKat version, it lists kernels in the download links. Would these kernels be included with the ROM files themselves, i.e. install at the same time as the ROM, or would I have to flash the kernel separately before flashing the ROM? Thank you VERY much in advance

The thread should tell you if the kernel is baked into the Rom our not but the stock kernel usually comes with it. I'm pretty sure you're talking about a beefed up kernel tho. You'll just have to read the thread and if you're still not clear about it, ask in that thread to be sure.

there is always a kernel included with a rom. most alternate kernels are made and or flashed to combat a side effect or incompatibility with some folks devices. its not that provided kernel doesn't work, just that every device is different and the alternates can sometimes be more compatible.
however, I would suggest you give the original kernel a chance to settle, at least a day if not two. if it just flat out is not working for you, then flash an alternate onto the rom. wipe you caches ( not factory) flash kernel by itself and your good
never want to discount reading here as Gimmeitorilltell suggests. reading educates you and puts you in a better position to help yourself first.

In general stick with the kernel that comes with a ROM unless you have a reason to change, like stability, overclocking, etc... but you do flash the kernel after the ROM; anytime after the ROM flash really. You don't need a clean flash before kernel switch.
The dev probably did not test his/her ROM with every kernel possible so if you want support your best bet is to be on the kernel included. For the 1st install of a ROM if you are unsure you should definitely use included kernel; as sometimes you just can't predict what changing it will do.
That said there many of us do switch kernels when installing updates, I certainly do. There are not alot of kernels for our phones as only a dedicated few devs continue to support the Note but you have a few choices. All kernels I've seen allow performance/governor control to some degree. If you read through the various ROM threads you'll find that some kernels are preferred by users but for the most part kernels like Uber work well with most ROMs.
P0llution's ROM patch allows you to switch kernels after flashing a ROM (BeanStalk, LiquidSmooth, etc....) and even before 1st boot. It also has patches for various KK problems. It is in the Beanstalk thread 1st post.
Thank you so much for your replies! Installed LS and flashed Uber kernel and running with no issues.
