[Q] New to nexus devices, kernel compatibility question - Nexus 7 Q&A, Help & Troubleshooting

Pretty simple one, Google search couldn't find me anything.
Since the device is built on AOSP, are there any compatibility issues with kernels and CM?
I'm used to being on touchwiz devices, and obviously only AOSP kernels would work with CM builds, not touchwiz ones.
I'm assuming that any kernel would work with CM, but I just wanted to be sure.
To that end, are there ANY compatibility issues with kernels and ROMs listed here?
Thanks in advance!

yeah all kernels work with all roms. i dont know if anything bad would happen, but i would advise against installing a 3g rom on a wifi nexus 7 and vice versa.

not really 4.2 kernel wont work for 4.1 and vice versa you should be careful when flashing kernels

Yeah, most kernels are listed for what they are compatible with. Keep your eyes peeled.

A question about ROMs and Kernels

Ok, so I've rooted and flashed rasbeanjelly from the nexus4root(dot)com website.
I've set everything up, down loaded apps I want etc, however I've heard that trinity kernel is very good with this ROM, if I'm wrong and there's a better kernel correct me. So how do I install the kernel? Same way I did the ROM? Is it compatible? Do I have to wipe everything? Is there a better kernel to use?
Thanks a lot for reading.

Just flash the .zip in recovery, no need to wipe anything. There's no 'best' kernel so your question about better kernels could easily get 20 different replies.
Ok thanks for your reply, what about compatibility? I've heard that if ROMs and kernels aren't compatible it can brick your phone

As long as the kernel and ROM you download are for the N4 it should be perfectly fine. In the future with new releases of Android there may be some issues, but devs usually make it pretty clear in the OP what you risk by flashing your phone.

rasbean and trinity are very compatible
as are all the other nexus 4 kernels.

(Q) Is There Any 4.3 ROM Truly Stock JSS?

I am looking for a completely stock 4.3 rom that is JSS, that is odexed; which means no theme capability.
Basically I want a stock factory image of JSS. So I can use jss kernels. And etc...
All I see are deodexed with some features implemented. If possible I would like to know if there's a version of this or not? Because I do not see one.
Sent from my Nexus 4 using xda app-developers app
Reason why i ask this is because all these roms' have bugs and issues where as the stock factory image does not.

If you used cm10.2 you can odex it with odex.me and I can upload that apk if you want. Cm is basically stock with a few improvements.

I don't want the improvement because those improvements involved bugs and problems any CyanogenMod build is always buggy there's not one single build that's a hundred percent perfect.
There are a few stock ish JSS roms however most of them still implement their own kind of features which I don't want. All I want is the stock image of JSS kind of like JWR OTA.

there is no actual stock JSS image. JSS is source only right now. You can only get the image for JWR. If you want JSS so badly, ask a developer to cook the rom for you without root. Only way is to compile from source.
This will probably be the closest you'll get. It has no root but has the Google apps replacing the AOSP ones so it's as close to a factory image as you can get. I'm about try it myself as I prefer to have 100% stock as well

Issue solved please close

Hey guys I just rooted and installed a few custom ROMs on my n4. When I install a custom 4.3 kernel on any 4.3 ROM I get ridiculous flickering issues. It never happened on stock and only happens on custom ROMs when flashing another kernel. Am I missing something obvious? I have searched for an answer but have come up empty. Any help would be appreciated cuz I really would like to run Franco or faux ( my two favs from my Gnex days). Thanks a lot guys
Edit: sorry I meant to put this in q and a mods feel free to move

Flash the proper kernel for you ROM hint there are two different builds for 4.3
Sent from my Nexus 4 using xda premium
I did flash the correct kernel. At least I think I'm running cm 4.3 (jss15j) and I tried flashing faux's latest 4.3 kernel. If that is for some reason incorrect which faux or Franco would u recommend?
Edit. Ahh I see what u mean by two different builds. Thanks I thought there was only one build on 4.3

Kernel question

Hello guys,
Iam new to the Nexus 4 forums. I have experience with other phones with flashing etc. I have a couple of questions:
I flash a kernel(zip) after I flash a ROM. That seems to me the right way. The flashing seems going right but after restarting the phone somewhat stutters, its no lag or something like that.
Iam running PA with now the regular kernel but when I flash Franco or Neo kernel it happens.
Anybody a idea what i am doing wrong?

For PA use jwr kernels. Not jss. Neo and Franco both have two versions. Jss and jwr.

There's also this zip which allows Jss kernels to be used in jwr roms.

which unofficial cm11?

There are some cm11 daily builds for our devices. Which one do you recommend to use? Thanks.
İ think you dont use cm11.. İ suggest psx rom.. Fast, smooth ve stable.. You should try it..you will like it
Sent from my Nexus 4 using xda app-developers app
I second this question. I've seen around 5 unofficial CM11 builds. Of those, which one is good?
Side question, so far, which 4.4 ROM works the best?
Sent from my Nexus 4 using xda app-developers app
İ am using psx kitkat rom.. While i using 4.3 i was using. My favourite is psx rom.. Exactly you should install and live speed
Sent from my Nexus 4 using xda app-developers app
the "what is best" topics aren't really allowed on this forum.
OP is asking about CyanogenMod, not PSX.
You should use Euroskank, it's the next closest to official ÇyanogenMod.

Most of them are going to be nearly identical unless the builder has added their own changes. I personally use these, just make sure you choose the ones tagged 4.4, as the poster also does 4.3 and 4.2 builds on a nightly basis.
I'd recommend building your own, if you're capable.
I normally flash whichever one is the most recently compiled. Got to have the latest version right? On the odexed version by Bruce and i think it's the best performer bit i always like euroskank. Always had features before they are merged
