[Q] Best ROM+Kernel combination? - Nexus 9 Q&A, Help & Troubleshooting

Yo! What do you guys think is the best combination to get reasonable battery life and good performance? Im getting 59k on antutu using AICP ROM and stock kernel. Do you think i could get more with some custom kernel ?

I am just using stock since Pure Android is what I want, with ElementalX kernel. Using ElementalX on my Nexus 6, Nexus 9, and GPE HTC One M8 and love it. I look forward to Xposed working with Android 5.1 and N9 being updated. I used to flash ROMs, but on Google devices Xposed is more then enough.

Im using AICP5.1.1 Rom on my N9.. Is it possible to just flash the elemental kernel without messing with the rom itself?

I'm on Dirty Unicorns with Fire - Ice kernel. Insanely stable and the most functional of the ROMs I have used.
As far as just running a kernel, yes you certainly can just flash the kernel w/o changing to a different ROM. But what's the point in that??

Can you please explain me that? Im still a noobie I tought that just by flashing elementalX kernel on my N9 I could improve AICP and overall tablet performance. I guess im totally wrong xD

Sorry when you asked the question, I didn't realize you were already on a non stock ROM. AICP already has it's own customized kernel. Yes you can flash any other custom kernel in place of the one which comes with AICP.

benifits of custom roms ?

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.

cheers guys i guess custom seems the way forward, just need to research the changelog of each rom that takes my fancy
thanks again guys !!
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!

with siyah 3.5.2 installed u can be sure that no brick bug for u
and u can flash any custom ICS or JB rom with it

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.

[Q] Will the new ota help make custom roms more stable?

I was just wondering if now that there is a 4.4.2 ota out for the DNA that it will make the custom roms more stable? I updated to it and kept root and it doesn't seem to be any different and I hate the stock ui. Want to go back to a custom Rom but they all seem to have some issue or other that gets old over time so I end up crack flashing everything on here every few days haha.

Yea I saw that a couple days ago. Guess I worded it wrong. Now that the droid has a stock 4.4.2 will the developers be able to take whatever parts they need from it to fix the bugs etc on custom roms? Or will the DNA having the 4.4.2 radio and kernels etc will it make the custom roms such as the m7 and m8 ports and Google editions of 4.4.2 more stable?
HTC did in fact release the 442 kernel source, so new 442 Roms will be stable and I can fix z and my beast mode kernel

4.4.2 Sense based ROMs definitely should be much better. The CM based ones probably not a big difference.

[Q] Ignorant Kernel Questions

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?

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.. ??

[Q] GPE and ElemntalX Kernal

Hey I just wanted to know if it was ok to flash GPE 4.4 and ElementalX Kernal? I'm looking for good battery life and have had nice luck with this set up - Mahdi Rom and ElementalX on my Nexus 5, which is my work phone. Also, could you provide a link to GPE 4.4 because i'm not sure if i'm looking in the correct thread. Thanks so much .

Yes it is perfectly fine to flash a GPE ROM with ElementalX kernel. On the link part, all I could find is this but I don't believe it's 4.4.4. You can look yourself if you like, I was just trying to give a quick response since no one else did yet.

[Q] Best kernel for LineageOS?

Hello, I was wondering which is the best kernel for Android N that gives out good customizability and battery life.
Currently using official LineageOS 14.1 (obviously) 20171011 Nightly + Saber's DorimanX Kernel v13.0b005.
Thanks!
You are currently using the latest and final version of the only custom LOS kernel available for the i9100. So you're choices are stick with it for a while or switch to the vanilla LOS kernel on your next update by just not flashing the DorimanX one.
You can still do some very basic tuning on the vanilla LOS kernel but it's pretty locked down, for stability reasons I suppose.

Thank you. I might be sticking with that for a while, as I also tried Skyline's kernel but I found that DorimanX is much more stable.
One more question, can I revert back to any CM12.1/13 ROM without doing any other specific work? (ex: repartitioning the device)

if you already have the repartition and last Isorec only makes the wipes and install the new ROM with their gapps
