About custom kernels - Nexus S Q&A, Help & Troubleshooting

I am a complete noob and I am so confused. I want to install the matr1x kernel. Do I have to have a custom rom? I don't really want a custom from. HELP

Are you unlocked and rooted with clockwork mod? You'll need to be first.
Flashed matrix kernel over stock ics myself a while back and worked fine. Just wipe dalvik cache in recovery first though.

I have done that.
Will I lose any data. Btw. Which version? Cfs or bfs.
What kernel do you recommend.

You shouldn't lose any data. CFS is aimed at multi-tasking, and BFS is more aimed at single-tasking, games, etc. CFS is everday normal use. If you do heavy gaming or other heavy single process stuff then go for BFS.
I hope this clarifies it some for you.
Matrix kernel is fine.

Also make sure you are flashing the correct Kernel for either GB or ICS. 11.5 I think is the latest for GB and 17.5 for ICS.

Flash voodoo kernel to stock ROM question...

Hey all,
I have a NS4G that is rooted with an unlocked bootloader. The only other thing I want to do is use that color enhancing voodoo mod for "richer" color on the screen. I noticed, however, that you need to flash a kernel that supports it.
Would I be able to do that now, or would have to load another ROM first? Just curious, as I would prefer to keep the stock interface...
Thanks a TON,
Matt!

You can flash the kernel now. Just wipe cache and dalvic cache before flashing it.

Netarchy for stability,Matr1x and Trinity for more performance and better battery life.

The only kernel I've had any luck with is the Matr1x series. Currently running v9.5 (the latest) and it's running great.
Smooth, stable, quick, and easy on power consumption. Supports Voodoo, bln, deep idle, etc.
NS4G NSCollab Sprint 1.0.51, Matr1x 9.0, Shady Arctic Blue Theme
Thanks guys....
That really cleared everything up.... I went ahead and flashes the CFS version of Matr1x 9.5. For good measure, I wiped the cache partition and the dalvik cache 3 times each before installing Matr1x from the SD "card." Now i'm off to tweak....
Thanks again,
Matt!
D'Oh! wrong section, please ignore.

[q] my screen is black afer installling kernel!!

I just installed the [Kernel]CM7 [2.6.32.45] on my phone with CM7 already installed. when I turned on the device after the LG logo my screen turns black?!! What coulfd be the issue...I apologize if i come off as a idiot....
You installed what kernel???
From who?
From where?
Cm7 rom has a stock kernel, so you must have flashed a custom kernel, did you check to see if it was compatible with cm7??
Yes its this kernel [Kernel]CM7 [2.6.32.45]. I downloaded from XDA and it says its compatible with CM7. When i rebooted the G2x from CWM the LG logo showed up and then went to a black screen
Just enable USB connection and put a different kernel on ur phone and flash it. Ur phone obviously can't handle the kernel

Which CM7 Kernels could the G2x handle fo.....Im new to the whole kernel thing & im tryna get some help & I want to get more power from my phone.
Each kernel is different for speed, battery life, experimental... so on and so on. Every chipset is different in our phones some can't handle certain kernels.

So what kernels would work on any G2x?? Thanks for the tip idk all our chip sets are different.

Don't forget to wipe cache, wipe dalvik cache, then flash kernel, then run fix permission, reboot, enjoy

Sounds they are referring to Faux's Kernel...
You have to match them up properly as CM7 just went through a few kernel changes and the Custom Kernel developers have to make them compatible. I think Faux has .44 out which is supposed to work...
Then you also have 4 options from Faux: Pre-OC/UV or Stock Speeds; and CM and DS battery drivers.

[Q] What's your favourite ICS ROM?

Hello NS community! I exchanged my Desire for my fiancee's NS and now I'm flash happy.
I intentionally did not ask what the BEST ROM was to avoid a flame war, so please share what you find to be your FAVOURITE ICS flavour.
Until now I tried CyberGR-MOD v1 but it was very unstable for me so I was unimpressed. Next up on the flash list are CM9 Alpha 18 and Peter Alfonso's ROM.
Suggestions?
Peter Alfonso ICS
Thanks, for now I'm running CM9 Alpha18 and seems to be quite stable.
I just flashed bixies' ROM last night and it seems to be very stable so far.
IMO, the real fun with Nexus S is the kernel, we have many great kernels for you to play with

Do tell!
Currently I'm using Matr1x-cfs_v14.0Matr1x-cfs_v14.0. OCed at 1460 and no FCs, no reboots, no freezes, just buttery smooth performance.
Slightly off-topic, but I have to say I'm terribly impressed withe the Nexus S - it's a very powerful device.

It has been feeling very smooth, at least in the few hours I've used it. We'll see how it goes.
AOSP+ and Matrix 14 cfs gives me a great combination of performance and battery life. I tried ICUP too and it gives great performance but battery life is better with Matrix.
So is CM9 smooth and stable enough to be used as my everyday ROM? Also, are there any posts or wikis about all the different kernels, guides on flashing and their pros and cons? My last dev device was a Blade and there weren't nearly as many different kernels and options available for that. Oh, and does CM9 come with a kernel..I don't need to flash anything else?

Yes CM9 comes with it's own kernel. It's a mod on the 3.0.8 kernel. CM9 been running on my phone for 6 days now without a single reboot and FC.

What I normally do is:
* do a full wipe (system, data, cache) if you are flashing a different ROM
* flash ROM first, reboot to make sure it runs properly
* flash kernel, wipe dalvik-cache (or also cache, just in case)
Always flash a ROM that says it supports your phone model. Also make sure that if you're using ICS ROM then flash an ICS kernel. On the other hand, if you're using GB ROM then flash a GB kernel.

Kernels what to use and what they do?

Well I'm still fairly new to this and looking to learn a bit more . I am pleased with my current Hellfire 2.1 now I'm looking to exntend my battery life to the best I can and I was told this can be done with kernels, Soo I was hoping I could get some suggestions and anything that could help me out understand this a bit more.
I am currently using some Faux Kernel that came with the current Hellfire phoenix release.
Lot of people say to use Trinity with this Rom but no one says why nor in the xda page of this kernel say much about what it does, I like to be well informed before doing any changes.
also how do you install a kernel just download and install from zip from clockworkmod recovery like everything else? or is there certain steps to it?
First off this should be in the Q&A...

I'm currently testing the trinity kernel, The 1.1ghz one for the better battery. Using hellfire phoenix 2.1 so far its the rom I've enjoyed the most.
Any other kernel that anyone could recommend for the best battery performance I could get I'm pleased with the stock performance of the tegra 2 I have no need for overclocks.
Harsh kernel is the best. Flash it and see for yourself

Morfic's Trinity ELP if your phone can handle it as it varies phone by phone. But I also use Faux123's kernels and they work well enough.

Don't flash it because you're using a GB based ROM...

When choosing a kernel you should first know that they all are, in the most basic sense the same, but have little tweaks that make them all different. I know that the Trinity kernel has the Voodoo sound driver built in that is much better than any other driver. Also when choosing a kernel you need to just try a few and see how stable they are as not all phones are created equal. Some can handle the Trinity kernel and some can't (and same with all others). When you find one that works well with you just stick with it. And, as I like to say, to each his own.

overclock cm9

So i just installed cm9, and my phone can only go to 1188mhz so how do i over clock because i know the sensation can go to 1.6
Install system tuner and try to raise the value. If not, install a kernel compatible with cm9 and u should be good.
On some of the early nightlies I was able to use faux123's 005b3 asop kernel and overclocked to 1.78. I only used it on a couple of the early nightlies. I tried flashing it a few days ago and got bootloops. I think that was on nightly 01, maybe 30.
Stock kernel works fine for me. Overclock will probably be available sometime down the road. Someone on cm9 dev thread is running faux's kernel now, apparently without problems. I guess YMMV, or maybe that should be MMMV.
Isn't there a kernel less than 1.78 like 1.67 or something. A 1.6 kernel should be ok and u don't need to turn it up to max.

For CM9, faux is the only one that maybe works as far as I know. There is a mod over in the dev forum that overclocks to 1.5, I think. Haven't tried it, so I can't verify.
cm9 was great, but it wasn't stable yet and couldn't be over clocked
so i tried aokp that wasn't as good the screen looked too small and spaced out, but yo ucould over clock. And unfortunately without me knowing my phone was backing up my apps, ON MY DATA, so i owe virgin about 200$ now =_= for using 70$
In the end i went back to arhd, do yo uguy have any recommendation.
Use faux kernel 005b3 it will over clock it to 1.728.and it is stable and will run great.I have been running it for 5 days no problem.

First make double sure the kernel is compatible with your rom and operating system and firmware . Then wipe cash.and dalvik cash, then flash like a rom. By downloading the Kernel to the root of your SD card and flash through recovery. I like 4 ext recovery. After wiping you install from SD card then reboot. Hope this helps.
Of course do the download first, then wipe, then flash
