[Q] Air Kernel for Nexus S - Nexus S Q&A, Help & Troubleshooting

Hi,
Today I installed xenon HD ROM on my Nexus S and later changed the kernel to AIR Kernel. There were 4 Kernels on (Air Kernel Weekly #311 for NS - 4.2.X & 4.1.X JB) for Other ROMs. namely Blue, Blue NHBM, Voodoo, and Voodoo NHBM. I basically did not know what they mean. But when i tried installed all other ROMS gave me problems being very slow and laggy. Some how only Voodoo worked okay. But some how Voodoo gives a yellowish tinge to my screen ( which doesn't appeal much to me). Can anyone help?
When going through some battery related threads on XDA some one mentioned that the combination of XenonHD and Air Kernel weekly is the best for battery management and speed. I did tweak with the processor speed to 1400 as MAX and tried various modes like performance, ondemandx, intellidemand, etcetc...but all are creating problem (laggy and slow processing).
Can any one suggest me alternate Kernels? which is optimal for the Xenon HD ROM?

Make sure to flash a CM-based kernel when using XenonHD.

[Q] combining stock ROM 2.3.4 with netarchy kernel

hi guys, i would to ask your advice..
right now, i'm using stock ROM 2.3.4 in my Nexus i9023 and i want to try to flash the netarchy kernel, most of people said it is the stable one.
my question, is netarchy kernel compatible with the stock ROM? is there any issues about combining stock ROM with netarchy kernel?
thanks

yes
no
as long as you follow the proper instructions on how to install it, it will work fine
I was running that setup for a while. Really stable plus better battery with undervolting.
Hey guys,
I've also installed NetArchy 1.3.7 CFS with my stock ROM 2.3.4 (i9023 model). I'm using the default settings (i.e. on demand CPU governor, max 1ghz, min 100 mhz). I didn't undervolt yet. So far my experience with it:
- recording video causes stutter and frame / audio drop at points. This is certainly a show stopper for me since the whole point to install netarchy was to be able to use Voodoo and record proper concert audio but now the video itself can get screwed in less than 60 seconds into a recording
- Battery consumption while idle seems pretty good... (sometimes getting 8 mA consumption according to battery monitor)
- Battery consumption when active seems pretty intense.. checking my e-mail with K-9 and firing up Facebook will start eating 300 mA).
So my first gripe is with the video recording. I'm already using the best CPU performance I can and I certainly don't want to overclock when the stock kernel was working fine (except for the sound). I might try other kernels (namely Trinity and Matrix to see what happens) but I like the stability of Netarchy though... in 1 week with it I only had 1 random reboot
Has anyone been experiencing the same ?
Netarchy is the most stable kernel. Mai ly because it takes the least amount of risks.

[Q] Question about custom kernels

I bought a nexus S yesterday (the 9023 version), so I unlocked the BL, applied the CWR and flashed the 4.0.4 stock.
However, I feel the phone has more to give (more speed). Also, I suspect that the wifi signal is weak. Which kernel should I apply? I was wondering if I apply the air kernel, but the overclocking to 1.4 ghz kind of "scares me". But I see that OC is applied in other kernels. So, is it provely safe or something?
Also, if in the future I want to go back to stock kernel, all I need to to is flash an official OTA update again (too lose the root and the custom kernel)?
thanks in advance to all!
The custom kernels really can extract more juice from the NS. Try the ones that fits best for you, IMHO the best ones are Steve Garon's, Air Kernel and Franco's.
You can manage the clocks and voltages with NStools, and you don't need to use a daily 40% overclock. These things you can test, each device responds differently to overclock. I'm have a i9023 and actually using 1.32 GHz, it's pretty good.
Also, the feel of responsiveness comes not only by the clock, but also for SD speed and RAM utilization. Franco kernel comes with stock clocks, but the speed when oppening an app or scrolling the photo gallery is very good.

Many thanks for your reply.
Maybe you can point the key advantages of those kernels in your opinion?
The main advantages for me are:
- More controls for clock scaling, you can define how your device will scale up or down the clocks in response to use
- Franco, Steve Garon and Air kernel have tweaks for SD card performance, the responsiveness when opening apps is better
- Steve Garon applies a 10% overclock in the bus, some applications that are GPU bound become more smooth, like browser (facebook and google reader too!)
- Steve Garon's and Air kernel implements methods for lower battery consumption when idle, even with overclock you can achieve the same battery consumption
Personally, my device is now much better than with stock kernel.

Thanks.
My current favorites are Trinity and Matr1x cfs. Steve Garon's kernels were phenomenal, but he's recently retired from nexus development.

[Q] Best rom and kernel combo?

Dear Nexus S users,
I tried alot of roms with my NS i9023 but I still haven't found the best rom + kernel combo..
I wanted to know what you think is the best rom or kernel or even both.
right now I use the latest Pixel Rom with Matr1x 19.0 kernel.
It works great but I still think I can get more out of my NS..
Thanks .
Hmm..im just using bugless beast rom..just satisfy even with stock BB kernel
Sent from my Nexus S using Tapatalk 2
Bugless Beast or AOKP are the only ones that seem to work for me without any issues. I've stuck with Simple Kernel since it's pretty close to stock and is the only one that hasn't frozen my phone up(my phone is temperamental apparently). . Best bet is to experiment. Not all phones are the same and results vary, as you can clearly see from my phone!
Thanks guys, I'll try the Bugless Beast
Androxide 2.0 with Trinity kernel works great. The kernel comes with a preset color configuration that has made the whites actually look white. And its great performance wise

4+ hours of on-screen use with the settings in my signature.
Nexus S (GSM i9020a)
GummyNex (4.0.4 - 102)
Matrix Kernel (CFS - 19.0)
Lionheart tweak (1000/100)
Deep Idle (Off - Noop)
So far oxygen with teuv for battery.
Anyone have good rom/kernel suggestions for battery life?
Using aokp and air kernels.

I'm now on the new rascream sandwich, with Eugene's Sppedy-7, and am loving the combo so far. Cheers!
cybergr v11 with weekly air kernel 4.0
HI guys, IMHO, best combo-duration is Androxide 2.0 - Matrix 19.0 (LIVE OC, DEEP IDLE ON).

Same rom but with AirKernel 4.0 Stable, Smartassv2/noop, 100/880mhz (liveoc 110%) & DeepIdle.
Right now using latest bugless beast with franco kernel..
I love matr1x kernel...but get some laggy when playing temple run...
will switch back to matr1x after reach 10 million for temple run..haha..
anyway franco kernel is damn fast..
150 hours without reboot dan still fast no lag...

stable ICS rom?

Hey guys, I bought myself a Nexus S one month ago and I've flashed about 15 different ICS ROMs. Is it just me or are there almost no stable ICS ROMs? All of them had random reboot issues apart from AOKP and CM9. I had no reboots on AOKP but the clock got stuck every 2nd day, so my phone wouldn't wake me in the morning which is even worse. CM9 I liked a lot, but I couldn't phone in the hands free mode (don't know the propper name of it in english) because the mic wasn't loud enough. Currently I'm on ras cream sandwich and it reboots while i'm listening to music which is really frustrating. Oh and before i forget, I always flashed matr1x kernel and used smartass governor, no OC.
Is there any stable ICS ROM apart from CM9 and AOKP? Or can i fix the other bugs?
Thanks in advance!
Your problem is the kernel, not the rom. My phone also reboots while listening to music in the undervolted matrix kernel. Stay with rascream and flash the _thalamus kernel and see how stable it is. That kernel is really stockish and stable. If you don't want to flash you could try to raise your voltages to stock values in nstools. Some phones like undervolting, some not. ;-)
Verstuurd van mijn Nexus S met Tapatalk
hm I didn't know matrix kernel was undervolted, I thought that's only the case with trinity TEUV kernel by default well I'll try another kernel for the time being and see how that goes.
Yeah. Some of our phones can't handle the voltages mathkids kernel supplies outta the box unfortunately. Either adjust them back to the stock ones or search for another kernel. I prefer either thalamus or Simple Kernel. I just recently flashed the latest version of the former and its great. You can try Air kernel if you want a few more governors and whatnot.

Like.. that's what STOCK is all about.
The people that made the phone are the most interested in making a stable ROM, no compromises.
Most stable and fast rom
Try APEX ROM 1.1.2 (latest release), that's what i'm using until aokp milestone 6 comes out. there is no lag, no reboots (just if u OC too much),...
Slim rom with no tweaks is smooth. Try it and u will not regret it.
Good luck
Vs Nexus S 4G
MIUI roms are very stable these days.

Well it differs from phone to phone. My phone is good with Matrix kernel. Might be one of the best custom kernels to run for my phone if not the best. Matrix isn't a compromise for my phone.

For several days I'm with Slim ICS and Matr1x and I have no problems with random restarts. No OC and no tweaks!
Try CyberGR ROM
I have installed CyberGR ROM and I have not suffered any reboot. I followed one by one all the steps of the development part and I'm quite happy with it.
Good luck.
Well, if you really want stable, get Stock 4.0.4. I'm on 1100+ hours on uptime without a single reboot... The only thing I've done to the stock 4.0.4 is getting root.
I would also like to know. from my own experience, stock 4.0.4 is best, but can CM9 very be made that stable? I'm running it now with ink kernel and no tweaks and it seems slightly laggy :/ should I flash brainmasters tweak pack?

Bugless Beast hasn't given me any issues. I've rebooted to flash other kernels but the only two kernels that have given consistent performance are Simple(stock with bln) and thalamus. Once I get my new battery, I may see how long I can go without rebooting. But if you want rock solid, go with stock ROM. Hell, my cousin has an EVO 4G and has almost 1200 hours up time. Lol.

AOSP+ definitely belongs to this category. Stock with a few useful modifications.
You should try AOKP again
I know you've already used AOKP but you should try/flash it again. I'm sure that the clocking was freezing because of some flashing issue.
Go to this link and download the milestone-5 version (m5) of AOKP. Also, you should use this rom with matr1x v19.5 cfs.
Milestone means that it's stable, so you shouldn't have problems with it. I use this rom and matr1x 19.5 on my daily device and haven't had any problems nor reboots. Great performance and great battery life too. Besides that, the rom is highly customizable.
Apart from stock, Have you tried BuglessBeast? Very stable. No need to flash any custom kernels.
if ur using ra scream use one of the trinity kernels. its super stable, super smooth, and long battery life
im using this black ice rom, in love with it .. shud try

I searched the internet and apparently I'm not the only one with that problem. I tried AOKP twice (i think build 32 or something and m5), always with matr1x kernel. Could this also be a kernel Issue?
I don't know that much about Android, but what I found out in the past days is that my Nexus S can't handle UV. I also get very high Android OS battery usage sometimes but I don't know why. High meaning Android OS once used more battery than display even though i had 2h screen on time. I suspect it's got something to do with titanium backup not restoring apps correctly, but that's just a stab in the dark.
Currently I'm on Apex v1.1.2 with stock kernel. No random reboots so far. I didn't restore apps via titanium backup (which was a pain in the ass). So far Android OS seems to use way less battery than before. But yesterday I had something like SOD when received a call while using TuneIn, so I had to pull the battery and call back. Not what I call stable.
I know that's a lot of text and probably also a bit OT sometimes but I hope some of you will read it , I'm not really a flashoholic and I'm getting sick and tired of switching roms, but I need my phone to be reliable. I'm really tempted to just switch back to stock ROM with stock kernel at the moment...
the things I'd really like to have is bln, notification toggles and stability.

Best Kernel

What do you guys think of the best Kernel for our Oneplus 6?
For me it seems like the Flash Kernel works the best but i would like to hear your opinions
Edit:
I listed my Stuff in an Excel Spreadsheet, currently running Radioactive.
Obviously each kernel is unique in its blood sweat and tears. Just try them all and leave em on for a few weeks. Usually the older toolchains have better battery and more stability in my testing. The benefit of certain kernels are exculsive CPU scaling governors modded by the developer. Currently running pappschlumpf's Smurfkernel with smurfutil battery profile spectrum on havoc nightly. I look for stability though and for stock OOS all kernels run pretty solid. One thing you need to be sure is that the kernel manager is locking frequencies otherwise I find a kernel that allows this. Lately I've had some trouble on blu kernel

Ive tested Stock, Elemental X, Franco and Flash Kernel in Idle Drain per Hour and Antutu Score
and Flash got almost as much as Stock in Antutu while only using 2.9% per hour
100% radioactive kernel
