[Q] Different TW-ICS Kernels - Benefits - Samsung Epic 4G Touch

Hello everyone. I have a question about all of those new kernels that are popping up rapidly in our community for ICS. I'm a pretty advanced phone user and I've been around the community for awhile so I know what a kernel is and things like that.
But anyways, I've been using EL26 fastboot stock CWM and EL29 stock CWM kernels before that to flash anything from ICS using Mobile Odin. Lately I've seen a ton of new kernels pop up and I'm wondering about their benefits.
Agat63's Repacked Kernels
Team Win Recovery Project Kernels
ReactiveDisorder's Kernels
I believe all of them are repacked with Recovery (I haven't tested them yet so I may be wrong) and they're all TW-based.
Could anyone explain what makes each of their kernels different and the benefits they offer? Do they bypass the emmc lockup or not? Which one is the most safe? I don't see how any of them could be drastically different because they aren't custom kernels since we don't have the ICS source yet.

Well for one thing, Agat's most recent repacks have some mileage on them with regards to being safe for flashing roms and wipes.

TWRP recovery/kernels are also known safe. There is a CM9 and TWiz version. I would stay from RADs repacked kernels.

Agat's and TWRP (for GB, ICS and CM9) both have code in place to basically prevent the edify scripts that were causing the EMMC bricks to even start. They are both safe for flashing.
ReActiveDisorder kernels blocked the wipe data option that was the primary source of the bricking. But it has been discontinued.
There is a safe CWM repacked kernel for CM9 and there is supposedly one on the works for AOKP.
For the most part what you are seeing are just stock kernels packed with a custom recovery. The really awesome kernels will be rolling out right as source hits.

SGH-I747 Kernel flashing 101

So I have got a question that maybe many others have yet to voice or address (maybe it's just me, and I am delusional). In any event, I am not new to rooting and flashing ROMS. I am also familiar--at least conceptually--with what the kernel is and what it does. For the purposes of this post however, I should mention that I have not ever flashed a custom kernel and am unsure as to why one would or why there is more than one floating around. I have been vacillating back on forth between stock and custom kernels....it seems like in order to flash this ROM you need this Kernel, or that ROM flash that Kernel. I want to learn and to know. I would really appreciate feedback on this.

Kernel's are installed or "flashed" in the same manner as a custom ROM, either through CWM or Odin. Kernel's just add an extra level of customization, most people use custom Kernel's for overclocking although they also have many other uses.
Kernals can also highly affect battery life and the speed of roms. The kernal has to match the kind of rom. Samsung kernals go with samsung/touchwiz based roms. Aosp kernals go with aosp based roms like cyanogenmod and aokp. There are a few jellybean kernals and those will work for the current jellybean aosp based roms. Samsung will eventually release their own jellybean update and when that happens expect to see jellybean samsung kernals made for roms based on samsung jellybean.

List of kernels that support custom boot animations.

I haven't seen this so I was wondering if we can put together a list of kernels that support custom boot animations. Go ahead and flame away if you think this is the dumbest thing you've ever heard. But if you agree... let the list begin.
For ICS
agats kernels
Sleshepic kernels
Kuban kernels
*FH13 repacked with agats recovery
GB
Hitman kernel
Rogue kernel
That's all I have right now. Lol and any other kernel that has bootanimation support in the op's description.
*just remembered the new kernel.

How do i use a rom with any kernel?

Hey all, i've been running through ROMs here going back and fourth trying to find the best one for me. And so far i love a couple of ROMS, but the only ROM where i get data speeds that are good is Snipers Lightweight ROM using EL29 modem and agats fl27 repack kernel. I want to be able to use this Kernel and modem on other ROMS (the blu kuban for instance), but it seems most of ROMs require a certain kernel. Is there anyway around this? so i can use whatever kernel i want on any ROM?

I don't think so. As you know, a kernel is like the base and the bridge between hardware( CPU,etc...) and apps. So if the rom isn't made for a specific kernel, the phone won't boot up
Yes you should be fine. The aroma installer included in Lightweight even has several different kernels to pick from, as they're all for ICS TouchWiz (like Blue Kuban ROM).
Now, if you're using a repack (like fi27), you won't have all the extra tweaking/over/underclocking options like you would from a custom source-built one. But if all you really care about is data speed then there should be no problem.

[Q] Can Any Kernel Work With Any Rom?

Hi I am new to rom and kernel flashing, and I am interested in flashing the ElementalX 1.1 kernel on AOKP. I love AOKP, and I am way interested in the swipe-to-wake and double-tap-to-wake features of ElementalX 1.1.
What kinds of things do I need to know about compatibility between kernels and Roms? Can you typically use any kernel with any rom?
Loving the Nexus experience and looking forward to learning more!
They often can but not always.
Android versions need to match.
Usually you can flash any kernel on any ROMs but if its a CM based ROM and you flash a custom kernel then slimport features sometimes don't work or some times you flash a custom kernel then the boot animation gets cut and turns black it doesn't really matter I have done lots of flashing and I would say that every kernel can be a flashed with any ROM without problems I am currently on CM kang and using kernel elemental x and everything runs smooth..hope this help click thankksss
Don't just slap any kernel to your device you might seriously brick it.....learned this lesson when I had an Atrix4G.....

Nexus devices are different then the Atrix4G. You can not seriously brick it by flashing an incompatible kernel. Even having no kernel will not prevent you from accessing the bootloader and recovery.

[Q] please help

Hello all. First I want to thank everyone for still being around to help, especially on such an old device.
Anyway, I recently bought one of these and got it rooted via odin. Currently that's all I've done to her. I have been looking over this forum, android forums, and Google in general prior to posting, I want to solve problems on my own, but when I can't, I'm not scared to ask for help. And I need help with a few issues. I will seperate them, to make answering them easier.
1) is twrp not available for this model?
2) if not, the only other recoverys I can find is Phils TouchWiz, and ClockworkMod recovery touch 5.8.1.5. I wouldn't think these are the same, which is suggested? Also Phils Touchwiz was last updated (that I can find) to 4.1.2 which is where I currently am, am I want to go to 4.4
3) I only see 2 ROMs listed on here, and 1 is one of the ones I was thinking of using in Dirty Unicorns. The other I was thinking about was CyanogenMod. Which of these two is suggested?
4) I have no service on this phone, as its my tinkering device. The only thing I need to work is WiFi. That being said, do I need to flash a new modem?
Do I need to flash a new kernel?
Thanks for any help you can throw me. I know there are lots of tuts for all these questions, but frankly they are all very old, and this stuff changes by the day...
1. Yes but this device has recovery and kernel built in together, this recovery is only for flashing / wiping, other than that, it is not usable with other custom roms unless the devs build it to use that
recovery along with the kernel.
2. It's the same as question 1, For Touchwiz Jellybean, you'll need a recovery kernel that supports the android version and firmware, otherwise it wouldn't work or boot up, Agat's Source GB27 for GB27 Touchwiz ROMs. Or specific AOSP Kernels for certain kernel build updates ( versions are compatible with the build date of the ROM's Original Kernel, meaning it only works on certain ROMs that are updated with the same kernel build, for example, A custom 0.0.25 will not work with stock 0.0.26 because there was a major update change in the kernel that'll make 0.0.25 not usable on it. If you use a kernel based on a specific date on an AOSP ROM that frequently updates the kernel, it may not boot up. )
3. The AOSP ROMs that are being updated at the moment are the Teams that do Nightlies. So Cyanogenmod is the only AOSP ROM that's being updated weekly for this device, I have not checked on the other ones.
4. No need to flash a modem if you don't have data service, however it may help either way when using WiFi due to dropped connections, stability etc. For AOSP, use any ICS modem, for Touchwiz, use the same android firmware modem.
Flashing a new kernel is not needed unless you don't like how the stock kernel performs whether if it's power saving or performance. AOSP kernels are kind of limited as the ones out now work with different build dates of the ROMs, Touchwiz has a couple, but Agat63's Source Kernel is recommended by everyone for GB27.
