[Q] Simple kernel question. - Nexus 7 Q&A, Help & Troubleshooting

Hi all.
I have a stock, rooted Nexus 7. I have flashed plenty of ROMs on my Droid phone...
Am I correct in assuming that I can flash a different kernel, say to underclock/over clock my CPU/GPU without having to flash a new, nodded ROM like CM10? I am interested in some tweaking, but I am running CM7 on my phone-- so stock JB seems just fine to me!
Any advice would be much appreciated!

Of course! Many people choose to stay on stock with a custom kernel.

ROM and Kernel

Hey guys have just installed taboonay's Rom on my Acer and so far it is not too bad. I am using AOKP on my Galaxy Nexus which is awesome, is there anything similar for the Acer. Also does anyone use Franco's Kernel at all? If not, what is a good one?

With ICS, there is only 1 OC/UV kernel, and that is by EZTerry. With kernels, each is specific to the device&OS, so you really can't swap kernels around. You can find EZTerry's ICS kernel easily in the Dev forum.
AOKP? At one time there were a couple folks tried doing a Kang but they were using a non-GPL kernel, so they were not allowed to post here.

Best rom for nexus s?

Hi all, there are many roms un development section but i m confused which one to flash...can someone help me? Which one is the fast smooth JB rom? And with which kernal?? Currently using PA2.54 very slow...

There is dozens of this exact thread in the Nexus S forums. A few active and talking right now in this very sub forum. Its all a matter of personal opinion. Do some searches, read some reviews, flash and try and base your decision by your use cause no one uses their phone the same way with the same signals.

You seem new to roms, its probably best for you to start out with this combination:
ROM: Cyanogenmod 10 Nightlies
Kernel: Default CM10 kernel
or
ROM: Rasbeanjelly
Kernel: Trinity kernel
Also heres a popular list of roms and kernels
ROMs: CM10 Nightlies, Slimbean, Blackbean, Rasbeanjelly, Strawberry
Kernels: Marmite, Matrix, Trinity, Air
You can find all of them here.

You need to wipe everything (except sdcard) if you're moving from a different rom (PA)
Just do a nandroid/titanium backup and everything will be fine.
Here's the link to stock, rooted, deodexed 4.1.2 rom: http://d-h.st/t7o

CM10 is your best bet, other ROMs like Rasbeanjelly+Trinity is also good too but it's more likely a gimmick imo.
Definitely start out with CM10. I just recently got into flashing custom ROMs on my Nexus S (was rocking stock for a long time), and CM10 + Marmite kernel (smartassV2, cfq, 200/1000) is my preferred setup.
I've also tried my luck with Slimbean and Strawberry 4.1.2, but both of them always had little annoyances that you simply don't have to worry about with CM10. That being said, the AOSP-based ROMs like Strawberry and Slimbean do run very smoothly. I do plan on trying out AOKP, however, as it has a TON of customization options and appears to be pretty polished overall.
Slim Bean is the best rom for me, but I can customize everything so I have no problem. For most people it's better to use CM10 and the Jelly Bean 4.2 gapps.

Both the ROM and kernel can have an effect on gaming performance. Try testing out another kernel to see if anything improves.
Like I said earlier, I highly recommend Marmite for the Nexus S. It has great performance and battery life.

Hi, I just rooted my Nexus S (Mobilicity) the first time and I have some question here:
1. Should I just install this CM10 nightly cm-10-20121115-NIGHTLY-crespo.zip (seems to be the latest) ?
2. I found gapps 4.2 here ]highonandroid.com/android-apps/googleapps-4-2-for-android-jelly-bean-roms-gapps/, Can I use this for CM10?
3. Do I need to flash radio for CM10?

1. Yes, that's the latest nightly. Should be very stable, as far as I know.
2. DO NOT download that gapps file. The one linked in that article has the old, ugly prototype keyboard and has force closes up the anus. You can search this forum for better packages of the 4.2 Google Apps, but they are all still a little too buggy or incomplete for my tastes.
3. No need to flash a radio. CM will not overwrite your current one.

in my experience, the best combo is:

Kernel AirKernel stable r2
the battery life is very good, there is no lag and with new ADW launcher, homescreen and drawer are very smooth

[Q] Does a custom Rom come with a Kernel?

Does a custom Rom come with a Kernel?
My specific case :
Nexus 7 32Gb Wifi
Android 4.1.2
Rom : PA 2.54
Kernel : Franco 3.1.10
My plan is to update to PA 2.99Beta6 which is based on Android 4.2.
I'd like to know if I'll also need to flash a new kernel as part of the upgrade process or if the PA 2.99Rom also includes the required kernel.
My guess is that it will be included with the Rom but figured it wouldn't do any harm to ask.
PMSL, how on earth do you think a ROM would actually work otherwise without a kernel.
Sorry but.... #facepalm

My fear was that a Rom might use or expect the stock kernel, cheers for the answer though.
With that in mind, I wonder why Roms don't tend to ship with custom kernels. Franco's seems to be widely preferred to stock.

most roms that are actually developed ship with custom kernels(like cm for example). roms that are just compiled from aosp source that have some mods added usually use the default android kernel(or stock roms with added mods). also, many roms ship with other custom kernels included. anyways, many others prefer trinity kernel

Sorry I may have picked up on your question wrong, but many developers, well in fact most would use custom kernels, some prefer stock, stock kernels are generally very stable but quite limited in what they can do, for example take the pretty amazing Siyah on Galaxy S3 which gives you the ability to dual boot different ROM, s, i had AOSP as my main ROM and a Samsung ROM as my secondary ROM which was great for a while but they novelty wore off for me as I really only used the AOSP ROM, not to mention over clocking , etc, etc, etc.
I use Trinity Seven kernel on the Nexus and i find that the tablet seems to charge faster than with the CM kernel that comes with Liquid Smooth ROM.
Hope that answers some of your questions anyway

Stock ROM and kernel play well together. Other than that no one can tell you, everyone has different tastes. Everyday we see these threads and the answer is the same, just try any and all that interest you.

Faux Mainline Kernel
Paranoid Android Pie 3.1
Genuinely the best combo i have ever experienced.
So smooth, lightning fast and like 4 days on battery.
TRY THIS COMBO
Although I'm tempted to try Omega soon !
I have had my N7 since pre order and I can't begin to tell you how many ROMs I have tried.
Dirty AOKP is the best I have used...bar none! Very fast, smooth and extremely stable. It has a very involved DEV who offers great support. It offers a choice of seven or eight kernels that you can choose when flashing. The latest build has Tablet UI that you can install without rebooting.
If you like your brother at all you need to let him try this!

Definitely dirty aokp with Franco kernel or m-kernel. Or rasbean is always a good choice.

This Rom runs really smooth & stable. I'm using it since Dec12 and no FC. With M-Kernel its amazing.

[Q] Advice for a ROM

Hi guys...
I have a N7 16Gb from october and I think thare's not a real reason to change the rom on this device...except the tablet ui and the general fun to make it!
Well...
I'm not here to ask you guide etc. but an advice.
What custom rom do you advice? many talk about Paranoidandroid but I try it on an old Galaxy Scl and it was pretty horrible and unstable...but on nexus seems the rom most supportend and with much more feature...
Or I'm attracted by the Dirk AOKP that seem pretty good....
Beside this....it's difficult also the kernel decision...
Franco Kernel? or M3 or Trinity? I'm not interested in overclock...
thanks to all in advance
no one?
No one is answering because there are a ton of these threads asked all the time. There is no best Rom or Kernel. Try searching and see what features you like or what sounds interesting and then just install it and see for yourself.
I personally like the Omega 3 kernel, OC is optional and it has just about every scheduler/governor you could possibly want. Performance and battery life are pretty much on par with the other top kernels. I haven't tried any ROMS mainly because the 2 I flashed ended up boolt-looping. So I am using the stock with some pretty major tweaks. I am a DEV on other sites and once I jump through the hoops to be able to post in developer forums I will be posting my own ROM. OC is for people who don't know how to optimize. *cough*

Modaco custom ROM (currently version Jr13) is light, mostly stock, extra features that help me are- prerooted, enhanced power menu, tweaked youtube app for video preload, enhanced quick settings panel, comes with gapps etc.
Modaco cyanogenmod custom ROM (currently version r4) consumes more processing power, based on CM 10.1 so has all its features, prerooted, more enhanced power menu(with screenshot and extended desktop options), tweaked youtube, enhanced quick settings(devoid of vol control), comes with gapps, comes with cyanogenmod file manager etc.
MCR Jr13 and MCMCR r3 are interchangeable with dirty flash so I get to retain all my apps.
M-kernel (currently a33 version) gives me ample undervolting option (lp, cpu, gpu, ram), and I can set minimum brightness with rootdim, so I can extend my battery life.

Don't know why people make thread to ask others what's best rom, kernel... Answers will be different from users and depends what they prefers, so it'll be difficult to make a choice because every answers won't be the same. What I did when i wanted to choose was reading threads and try by myself to see what I liked. Sorry if my answer will not help you to choose but it's the best i can advise you. Hoping you find what best suits you.
Phone: GT-I9100P

Xenon
Im usin Xenon HD its a 4.2 rom (aokp base) and it's very customizable for your likes. You should give it a try.:cyclops:
If you are doing any ROM other than stock, I suggest AOKP for sure. It has a ton of mods for your ui and allows a lot of customizing. Make sure you get 4.1.2 milestone version and get your gapps as well or you won't have necessary files. Hope this helps look in the aokp official thread for download

thanks to all...
all advices are really usefull to understand the mod world...
I was intent to install an AOKP rom, but I don't really understand the difference...
I would like to try the the paranoid but i think is AOSP...
for AOKP I don't know what rom to try...I see the Dirty AOKP but I'm not sure....
There's also one called smooth ROM check it out, you should search YouTube to see if you like it. personally I'm back to the to the 4.1.2 stock rom because on aokp it wasn't allowing me to install some APK's from the play store that i really wanted. it said they werent compatible with my device when I knew they were compatible with n7.. I wish there was a way around that but nobody on here would tell me if there was or not when i posted a thread asking... anyways hope you find what you are looking for and I do suggest checking YouTube first for custom Roms for nexus 7 before flashing over hella different ones it would take less time, peace and good luck!
