I had all my phones before my 9s running custom kernels because i could tweak many things about performance and battery life but this phone seems to have most of that already because of the sd720g and large battery. Is there any reason to try to install a custom kernel?
If there's a compelling reason, which custom kernel do you recommend for miui-based ROM or other custom roms?
After many attempts to find a kernel that can make my phone better than stock miui-based roms I have come to an important conclusion. There is no benefit in flashing a third party kernel at least on official miui or other roms based on miui. Custom kernels on miui have bugs that developers didn't quash before moving on to make the kernels aosp compatible. I noticed significant variance in the performance and stability of my phone running miui. On stock miui-based roms the performance is consistent whether you are using the phone normally or using benchmark apps. On benchmark tests the stock kernel always gets highest scores consistently but using custom kernels you get big fluctuations and none of the scores ever reaches the level of the stock kernel.
People using aosp and lineage based roms highly praise custom kernels so they might be better than the kernels their roms ship with. I haven't flashed any aosp rom on my phone nor do I have plans to do so. This roms have some serious inherent issues that I'm not willing to get bogged down with as my phone is my daily driver.
I hope this thread helps anyone who is wondering about kernel flashing (on curtana) as I was before embarking on the journey to find out for myself since I got no replies.

Always better to wait official source kernal As long as your phone ( daily driver ) "Always Official for Best experience". Thanks for your detailed feedback
Did you use Pixel experience Recovery ? If you did, Could you provide me your experience with it, please?

I have flashed Roms and Radios, but have not yet flashed a Kernel. Does this mean that my T-Bolt is using the stock Froyo Kernel, or was the Kernel replaced each time I flashed a Rom? Thanks in advance for your replies!
Each ROM comes with it's own kernel. Usually the one it comes with is the best fit but not necessarily. Not all kernels will work with every ROM. See your favorite ROM's thread to find out about kernel compatibility.

Thanks for helping me to better understand this!
If you're using gingerbread, there's only 2 kernels available for flashing. Imoseyon's, and Dreamkernel. Most will use one of these two. Synergy and Gingeritus3D use Ziggy's, which are generally custom built for the ROM and are the only kernels that will be fully functional with these ROMs. It is possible to extract the kernels from one of these ROMs and use it with another, but you will have issues with it. Unfortunately, Imoseyon hasn't been terribly up to date with his kernel, which is the source for dreamkernel and Ziggy's. Ziggy has been building kernels for years now and has kernels out for 4 or 5 devices and currently has the only custom kernels that are fully functional with the latest GB leak. I've toyed around with extracting it from Gingeritus3D Beta6, but frankly, I don't have the time or interest since Chingy's ROMs have been my daily drivers for about 2 years now. I do have an older Ziggy kernel that was extracted, and if you want to play with it, I can send you a download link.

Good point. Too bad AOSP makes me wanna bore holes in my head. Every time I pick up a phone with AOSP on it its set up different and works different! ...but its what the girlfriend likes so I flash the crap and walk away. I really need to get her doing it herself!
I know that the overclocking possible is pretty low (I've heard 1.1Ghz is really all it can manage).
But i'd still like to try. I'm running a custom ROM currently and know it involves flashing the kernel.
Does that require a wipe or anything? And are all kernels compatible with custom ROMs? Thanks to anyone to answers..
The only kernel with 1.2Ghz overclock is doomkernel. I used it before at 1.2Ghz and no problems came up as I only use it when I'm playing heavy games.
All kernels should be compatible to all custom ROMs, except for FXP CM7 which requires it's own custom kernel or DoomKernel FXP-CM7 and requires an unlocked bootloader.
The same goes for Luke's MIUI ROM(and all that's based on it), it requires Luke's custom kernel, or DoomKernel for Luke's MIUI.
Other than that, they should work good with any custom kernels/ROMs. And no, installing a custom won't wipe anything. But it is recommended to wipe the cache and dalvik cache after installing a custom kernel.
i think the x10_029e_Th Kernel also has 1228mhz overclocking. But yes i heard somewhere the safe value is around 1.1Ghz.
Okay thanks. I have another question:
I've looked, and a lot of people recommend the TEAM ROM. But there's also the Th ROM.
I was thinking of changing off the MIUI one I'm on now. Which of those two would be best? I'm looking for performance

I am running the ThGO2 v7.5 ROM atm, i find it extremely smooth. TEAM is pretty good as well, how about you try out both of them and be the judge of it yourself as i don't find much difference in the roms unless there is major lag or something.
Well I'd love to try both, but I hate having to wipe all my data and stuff all over again.
What's the differences really? Just in a nutshell.

I think just basically the visual features are different. The performance as i said i don't notice much difference but TEAM does offers their app "Appman" which basically shows you all updates for their roms etc and different roms include different apps which i can't remember specifically which apps are included in which rom. So just try them out, i don't think you would be disappointed with any.
Okay. I was reading the Th one, said you have to backup APN? Is that data?
And I also saw three different builds for that one (stock, CM, and some other one). What are the differences there? CM has "Super speed" next to it, is that a faster ROM?
quick question,
basically what are the benifits of custom roms compared to stock kies roms ?
i currently have rr 2.2 rom but appart from the looks and animations etc.. is there a difference in performance/ battery compared to stock?
its been a while sinse i have been on stock so i cant remember what it was like and i just wanted to know are custom roms more better in terms or speed/battery/power etc..
thanks

custom rom do come with there own pro's and con's u have to check the changelog of that rom to see whats different in it also some apps which do require root previlage wrks fine with custom roms rather than stock one's
stock roms do have better batt life compared 2 custom ones at the cost of customization with there dull and boring looks
thanks for your reply i guess its just finding the correct balance between customization and battery life then. cheers
go with custom
I had the exact same thoughts when i first decided to flash a custom rom.
Personally i would now flash a custom rom at the drop of a hat, however as the previous comment said there are pros and cons.
do some research on roms with functionality that you require and you'll find one you want to flash no doubt.
hope i helped
i am now running CM9 and its so smooth and looks amazing, a millions times better than stock in almost every way!
Check out the ROM and the comments which people have wrote. Some of them may be good and others may be bad.. you'll be able to work out the missing features of the custom rom bother you or not ^__^ That's how I work out whether to install the ROM XD Most ICS ROM's have their benefits and cons, Gingerbread would be considered the most stable Hope this helps you

Highly customizable. You can overclock, undervolt, theme, use different launchers. To me they're faster too.

What about if I install a custom kernel, but keep my stock rom? Is there any benefit at all?
To clarify: I'm on i19100 4.0.3 which I've recently rooted. Thinking of installing Siyah 3.5.2 but for now I want to keep my stock (Bell) ROM. What do I stand to gain when I get the Siyah kernel, if anything? Or is the kernel really *only* just a prerequisite to get a custom ROM?
Thanks!

But there's already no brick bug on 4.0.3 right? So... what exactly would I gain with the Siyah kernel?
The only thing I can think of is CPU/kernel modding

One BIG reason I'm on stock ROM and KERNEL is that currently no custom Kernel supports MHL (please correct me if I'm wrong)
For me this is a big problem as I'm always watching movies and playing games on my TV with my phone

It's the ROM, not the kernel, that determines if MHL fully works.
Apparently video works with AOSP, but not full mirror of the display.
However, if you want full mirroring, you'll need to be on a stock Samsung based ROM.
That said, you can still run a custom kernel, such as Siyah or SpeedMod, and MHL will still work as long as you remain on the Samsung based ROM.
I'm currently running stock XWLPX with Siyah 4.1.4, and MHL works fully for me.
Hey y'all,
I'm going to feel like a bit of an idiot writing this given I've been using the XDA forums for close to 2 years now, but why should I install a custom 3rd party kernal?
I've unlocked my bootloader (finally) to get android 4, and as I understand I can now install custom kernels if I so wish. I'm not too bothered about the process or requirements for doing it, I'll cross that bridge if/when I get to it xD
I understand it can really mess up your system too, so why should I mess around with it for only (minor?) Improvements?
Also, why do custom ROMs have their own kernels? How does a ROM interact with a kernel?
I'm sorry if these is a really stupid questions. Just one of the few things I've wanted to ask for a while now :')

Using custom kernels with custom roms enhance tha rom cos most custom roms work more better on custom kernels...
A custom kernel can be pre-rooted, support OC, vpn support & many more... Some Custom kernels re better dan stock kernel is terms of battery life, smooth & respond!
Messing with tha system can help alot by removing bloatware which slows tha phone & occupy spaces & also customize yur mobile to yur taste!

For the most part, using a custom kernel or the stock kernel is better for a variety of reasons. Mainly, the custom kernels are usually always better than the stock they are based on. They generally run smoother and faster. Yes they are definitely improvements, whether they are small or big, they are still improvements.
Depending on if you are going to use CM roms or even AOKP roms, over stock roms (roms based on stock firmware) will depend on the need of a custom kernel. If you want to run CM or AOKP then yes you will have to use a custom kernel. If you are just running a stock rom, whether it is based on stock or it is the stock firmware, then you dont necessarily need a custom kernel, the stock kernel will work.
But if you want my input, then i would say go for a custom kernel anyway, even if you are on stock. The benefits out weigh the drawback if you can even call them drawbacks.
Hope I've helped,
Cheers,

The way I see it is like this.
Suppose you get a PC with a BIOS and OS locked.If you can flash a newer/modified/improved BIOS along with a tweaked OS,wouldn't you do it sooner or later?!

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.
