I have a noob question regarding flashing a custom ROM with the HOX+
1) Do I always have to flash a kernel when flashing a rom? If not or if so what are the benefits of doing this.
Thanks all. I look forward to being able to help other users as I lean more.

from my experience with flashing a few ROMs, the kernel, usually but not always, included in the ROM.
some ROM like AOSP/AOKP for our device don't include the kernel.
I'm a noob myself so dont take my words for it :laugh:

You don't need to flash kernel every time you flash custom ROM as long as your kernel is compatible with the ROM. For example: if you already flash nik3r's elite kernel, you can switch to every sense ROM without flash kernel again. But if you want to flash AOKP/AOSP/CM ROMs, you need to flash spesific kernel, which is maxwen's blade kernel.
Thanks perfect explination

While on my old Sensation, i often flashed diffrend roms, but never a Kernel that was not includet in the rom.
From what i have read in this forum, youd could increase the batterie time, if a custom kernel is flashed.
The tutorials for flashing a kernel are well writen, so i don't see a problem here. And yes, i am aware, that i nee to unlook the bootloader to flash a custom kernel.
My question is, how to chose a kernel? For what information do i have to look?
And for understanding. Do i have to flash another rom to get a custom kernel running, or could i stay on the stock rom and try the kernel itself?
Does a custom Kernel mean, i loose some of the functions that are in the stock kernel /rom or do have all kernel the"basic" functions of the stock kernel and just have addional functions and optimization?
Thanks for your time and help.

You don't need to flash custom kernel to increase battery life.
All you need to flash a custom kernel is unlocked bootloadr. Be sure to save DRM keys if bravia engine is important to you.
Then look for a custom kernel for stock roms, and custom stock tom too if you wish, or you can choose a non-stock based rom abd kernel.
Can i Flash a ROM without unlocking bootloader?
What are the best ROM's you Prefer?
if, What ROM You Are now Using?
If i Flashed a ROM, Will i see a Significant Speed Up?
Why You Flashed a ROM?
Thank you so Much, i'm noob in flashing roms etc.

For your information custom rom has so many features and tweaks to improve stability and performance so you decide what you need and what you don't need

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.

So I've tried a bunch of different ROMs (CleanROM, Alliance, Beans, CM, OMNI, "Stock", probably more), but I've never really understood kernels. It seems some custom ROMs have a kernel built in (or several to choose from via Aroma), while others do not. Right now I'm running AOKP (4.4.2) with the kernel from OMNI (3.0.64-OMNI-g5f47648), presumably because that was the previous ROM I flashed with a kernel. I'm not too concerned with customization, more with stability.
I've been having a few minor bugs and crashes and I'd like to try perhaps the stock kernel to see if that might help, but I have some questions:
1) Does it matter when flashing a kernel whether the ROM is TW or AOSP?
2) Are there multiple versions of kernels that correspond with the Android version of the ROM?
3) What's the best/easiest way to flash a kernel, presumably through the custom recovery like a ROM?
4) Where can I find the stock kernel? I found this thread (http://forum.xda-developers.com/showthread.php?t=2610870) with the stock MJ9 kernel, but going back to my first two questions I'm not sure if it would work with my current ROM.
Thanks ahead of time for any insight anyone can provide.

1) Does it matter when flashing a kernel whether the ROM is TW or AOSP?
Yes. TW and AOSP kernels are different.. The only one, that I believe, that can be used with both is Devil kernel for Dual Booting
2) Are there multiple versions of kernels that correspond with the Android version of the ROM?
Yes. Usually every version of android that gets updated.. the kernel does as well
3) What's the best/easiest way to flash a kernel, presumably through the custom recovery like a ROM?
Yes you can flash kernels through a custom recovery. Most of the time they are included with the Rom that you flash. A lot of the custom ones out have flashable zip for you to flash them through a recovery.
4) Where can I find the stock kernel? I found this thread (http://forum.xda-developers.com/showthread.php?t=2610870) with the stock MJ9 kernel, but going back to my first two questions I'm not sure if it would work with my current ROM.
No this will NOT work with a AOSP rom.. The kernel will be specific to that ROM and every other TW 4.3 ROM, but NOT AOSP

Thanks for the explanations, that helps tremendously. I'm confused now, however, because several people on the AOKP thread (http://forum.xda-developers.com/showthread.php?t=2453566) claim to be on "stock kernel". Is there a stock kernel for AOSP that I'm missing?

Well that's what I thought, but why then would I be using an OMNI kernel (3.0.64-OMNI-g5f47648) when I have flashed the last three AOKP nightly ROMs that have come out? Or am I missing something here?

Maybe he uses that kernel.. AOSP kernels, I believe are pretty similar.. I may be wrong, I am by NO MEANS a kernel guru..I would open you zip of your ROM (AOKP) and take a peak.. if there is a boot.img than it flashes a kernel.. and if your says OMNI then thats the kernel the dev has used..
Stock
If I'm on the stock rom and want to go back to the original kernel can I just restore the boot img in recovery?

Should be able to if you back it up previously.. but make sure it is same rom.. TouchWiz for TouchWiz.. AOSP for AOSP

Thank you sir. It worked just fine.
I have a noob question, I'm currently using n3bula 3.9 custom rom and it's been running fine for a while. I noticed that users chose the agni kernel whereas I chose the stock one. So my question is, is it possible to flash just the kernel from recovery without losing my data? I've spent so much time and effort customizing my phone, therefore, I just want to change the kernel. Any help will be appreciated. Thanks.

I would think that as long as it doesn't break anything you should be fine. Probably do a backup first if you're worried about it.
Thanks for the response Michael, however, that was the response I was dreading! I'm actually worried I'll lose my WhatsApp and Viber accounts because even if I backed up my data, I'd still have to register my old WhatsApp and Viber numbers all over again which I don't have anymore.. ??
Hello! I'm currently on stock OOS 3.1.4 with TWRP and I want to install Lineage or RR 5.8. Do I need a custom kernel? On this posts says "Linux 3.4.x". It's the same with stock kernel? I'm a little noob on this, haven't installed kernels before. Thank you!
Hello .
Ahh your first rom . Hope yours goes better than mine xD mind you it was slightly harder to flash when I did it
(LG Optimus) that's how long ago it was.
Normally kernels are bundled with roms. So you don't have to worry. In 4 years on this forum I've never flashed a kernel for the use of a rom. There are plenty of kernels you can flash after if you like. But normally if you flash a kernel before flashing a rom. Rom will override your kernal
Hope I've helped .
Give me a Thanka if I have
