school me on Kernals

How do you install one, same as any other zip file flash?
What are the different options for an incredible?
I am currently running the a 2.2 leak and will be flashing to the newest leak once the dust settles on all the different version popping up. I do need WiFi tether working too. I don't care about getting some great score on a benchmark app, just want to see what kernals offer to a normal user.

Yep, installed just like any other zip.
We have Hydra Kernels and Kingklick Kernels
Hydra - http://forum.xda-developers.com/showthread.php?t=701282
Kingklick - http://forum.xda-developers.com/showthread.php?t=760050
Both of them support wireless tether, its just a matter of reading up on them and choosing which one you personally prefer. I use the Kingklick BFS #1 Kernel.

Is there any major difference between hydraulic and king?

you'd have to read the change logs. They both run various OC and undervoltings to save battery life while maintaining performance.
I've ran hydra .3, .5, kingklick 1,2,3 and so far KK #3 has worked the best....can finally get ~24 hours out of one charge on stock battery.
Best would be to nandroid backup and see which one works for you the best.

Best Kernel for OC+Battery save.

I searched the forum, but so far I haven't found anything conclusive.
My question is, which is the best kernel in terms of OC possibility and battery saving?
I like the Kernel from the DK froyo RoM but the fact that I cannot overclock past 528 MhZ bothers me.
Note: I am currently on the Nightly CM7 Kernel which seems to drain the battery rather quickly and for some reason does not see my wifi hotstop -_-
Any suggestions?

Im on CM7 nightly to (#152).
Battery is a BIG problem! Also When charge gets to 80% the green charge light goes on?
I think it kernel related!
I also want to overclock to 710 Mhz at the minimum!

Indeed the cm7 kernel has some big problems. So far i've found out that with it you cannot connect to wifi hotspots, cannot detect wifi hotspots, it drains the battery too fast, and usb debugging doesn't work...
Nevertheless, I have replaced it with the one in my sig, but am still opened for suggestions for a better kernel.
The default kernel from DK Custom Froyo v 4.5.1 was good, but it didn't allow OC.

Thats interesting guys, I've been looking for a ROM for my wildfire, but my main concern is BATTERY LIFE.
I thought CM7 was supposed to increase battery performance? Should I be looking somewhere else? I'm just after something a little more responsive, stable, and an increase in battery.

Results vary widely. I am getting impressive battery results with CM7 (~3 days, with moderate usage), and I am very happy with it. However, on an initial install of CM7, battery life is terrible, but, after 1-2 discharge charge cycles, it somehow automatically fixes (calibrates) itself.

ah, thats great news, I was hoping for longer battery life
CM7 does seem to be the most popular ROM and has the most development. I'm sure I can live without Sense, but it is tempting to try some of the tweaked Sense ROMs to keep things looking familiar. Any recommendations on that?

JokerDroid is the current favorite , seeing its popularity. But the only one I have extensively tested is WildPuzzle 2.2.1, and, I liked it a lot. So, you might want to consider that as well. (With a new kernel, not the included one)

awesome, another one to test on my list
I've already downloaded Jokerdroid, no reason to change the kernel on that one?

No, it already includes the nFinity kernel.

Really appreciate all your help 3xeno!
So I'm now running JokerDroid, which has the nFinity 2.6.32 kernel. Would there be any benefit to dropping the nFinity 2.6.35 into it?
Also, with regards to overclocking, is there any way to control the overclocking that is built into the JokerDroid ROM?
I'm thinking of minimising the overclock, to try and get the best battery life.

I don't think so. Besides, I think 2.6.35 is Gingerbread only.
You can use an app called SetCPU to change the OC values, and add new profiles as well. The dev has uploaded it on XDA in a thread somewhere (Just search for it, you should find it without any issues)

ah, great. Yes I found the SetCPU app, but I wasn't sure if using that would conflict with the settings built into JokerDroid.
Guess I'll leave it set as it is for the moment, then mess with the settings in SetCPU if I feel I need to squeeze more out of it.
Thanks again!

cm7 works great! Have gone 3 days without a charge

Is there any Kernel with OC and WiFi working that doesn't cause copyBit errors?
I'm currently on nfinity-mc4 and it just messes up logcat completely.

So should I install nFinity 2.6.32 or this one with its useless filesystems? The upstream arco repository is gone and I'm not going to compile one from kernel.org for my primary phone
And can I use ClockworkMod 2.5.0.7 to install? My phone has S-ON and stock 2.2.1 rom (rooted, of course).

Best current ROM/Kernal?

Hi all,
I'm a new Nexus user and I was just wondering what is currently the best ROM and Kernal people are using. I put Android Revolution HD on my Nexus a few days ago and it's running great. I keep hearing people talk about Cyanogen or the Franco kernal though.
Are the performance improvements that much better, or should I stick to Revolution? I don't require a lot of personalization in terms of how things look. I'm quite happy with the stock look of the phone. I just want all the "behind the scenes" improvements like better battery life and loading times. What's the best setup in your experiences?
Thanks!

I've played around with several of the roms and kernels, with mixed results. It seemed like some roms and kernels would get me crazy performance, but really crappy stability.
The setup I'm running now is a cleanly wiped install of GummyNex 0.8.1 found here, or more directly here OnDemand governor is giving me respectable battery life. When I'm running short, I'll switch to Conservative. I've been meaning to set something up in Tasker or Setting Profiles to do it for me.
And Google apps found here, also more directly here
The kernel I run is Trinity, found here
If you haven't done so already, I found awesome performance improvements by opening the egl,cfg file in /system/lib/egl/, and deleting the first line- usually "0 0 android". Then going back into the egl folder and deleting both the .bak file some editors create, and the "libGLES_android.so" file. This is an ICS tweak that alleges to eliminate CPU rendering. I know there's an option in developer tools to "force GPU rendering", but apparently that doesn't quite cut it.
Anyway, that's my 2 cents, and it's blazing fast and stable. Averaging around 3800 in Quadrant.

Thanks! Revolution HD already does GPU rendering so I'm not to worried about that. I guess I'll just stick with that since it's basically stock with a few performance tweaks. I'm not big on instability :/.
The Trinity kernel looks interesting though... Is the overclock safe though? And does it drain a lot of extra battery?

Revolution HD is based on 4.0.2 so many kernels will not work because they are based on 4.0.3 and 4.0.4. I highly recommend you use a rom that is based on 4.0.3 AOSP (Such as GummyNex or AOKP). 4.0.3 has better stability/battery/performance tweaks anyway. If you want a better selection of Trinity's kernels go here. TNP1344-ANY-384-aelp (dated Feb 27th) is really nice. If it gives you bootloops up the voltages by 50 or 100.

aokp.27 + glados.v.1.18 OR leankernel.v.2.4.0 (both are stable as a rock)

Alright, I'll try Open Kang I guess. I'm so new to this... Sorry for all the questions :/.
It seems like a hassle to reinstall all your apps often so that you can switch to a new ROM . Does this need to be done every time the device changes its firmware version?

Well... you can always backup your apps with Titanium Backup, and save all your preferences (such as Nova Launcher, Minimalistic Text, etc.) and then reload that. And usually if you stick one one Rom and then an update comes from that rom, you don't have to wipe data (just cache & dalvik cache). But if you're switching Roms, then yes, you have to reinstall all your apps.

with titanium pro its a matter of minutes, saves your app-data also, so you don't loose your highscores. but as was mentioned before, updates go through without factory-reset most of the time once you're settled.
btw, aokp is perfectly stable.

I'm running gummy with the latest lean kernel and love it. Battery life is great and performance is top notch. Big fan of team gummy. I get a solid full days use regularly. usually around 20% when I plug it in after 16 hours of use and I use it fairly regularly, wifi, 4g, txt, web, etc.

Anybody Returned to Stock after trying different mods and Kernels? Tell us about it.

Hi,
I have played with my Gnex for the Past 4 months (Released Dec 8th in Canada). I have installed many mods, kernels, ROMS (Currently on AOKP MS3 and Francko Kernel MS1). I love the utilities provided by these custom apps, but I keep having stability problems from time to time and its getting a little bit disapoint.
* My Juice Def apps gets killed and settings are reset.
* I only see 50% of the pic when people call me.
* Volume is at max, but cant hear my music because of ambiant noise (to tell yuo hoe low the volume becomes)
* I Dont know how to use he Undervolting and Overvolting of the CPUS, and I dont realy care (Too technical for me)
* Whatever ROM is used, it still sucks my battery. Juice Defender is very good at doubling my battery life.
These are some reasons that I might bo back to STOCK KERNEL and ICS.
For those of you who returned to STOCK, Did you miss all the tweaks ROMS and Kernel gives you? Do you notice a different in speed?
Thanks.

Sounds like you're overall not happy with your experience.
If all of these cool tweaks are making it so you can't regularly use the phone like you like it, just return to stock. Its not worth sacrificing your enjoyment of the phone just to get some cool tweaks.

Problem is.. I dont really remember how its to run a stock phone. :S

same here..i also would like to go back to stock..

Then do it! No one's stopping you. There is no shame in returning to stock lol. Its okay.

I want back to stock for a day and changed my mind.... main reason that I don't like the stock is lack of toggles and overall smoothness. Oooo and you have no idea how often I use search icon on navbar . Also this is my main way of communicating with people. Voice actions are brill testing and calling is very easy with this. Someone will say that I can do that from search bar .... yes but 9 out of 10 times I'll miss tapping the icon ....

Did I return to stock? Well, after successfully compiling my first ROM (AOSP 4.0.3) I found out that my backups were deleted so I had to reflash some stock images from Google. I'm having enough fun playing with the phone on my own...I can be patient to see what improvements other ROMs come up with.

I am running AOKP MS3 and have been flashing the latest Franco kernel. I had the same issues as you and a full wipe and reflash solved all of those issues. Hope this helps you!

1. I use juice defender too and I NEVER saw it getting killed. The settings do reset everytime you flash something even if you don't wipe cache but that's the developer's problem no the roms/kernels. The solution is simple : just backup your settings from JD's status tab and restore it after you flash zips in recovery.
2. Well known issue with m3. there was a fix zip floating around but you should just update. m3 is not anymore stable than the newer aokp builds. b26/27 are very stable but just wait a few days and m4 will be out for sure.
3. I'm not sure what you mean by that. Are you saying you can't hear the music at 100% volume? Does it go away with stock kernel? then it might be franco's volume hack. Try leankernel 2.4 if you want something lean, fast, with GREAT battery life and without all the extra bells and whistles. you need to go to rootzwiki.com to dl leankernel.
4. You don't need to undervolt with gnexus and even if you do, it's completely pointless. It causes instability and the battery savings are negligible.
5. Wipe data and cache and flash leankernel 2.4 and aokp b26 (or m4 when it comes out). You'll lose all your settings but I think this combination will keep you happy for along time.
6. I used JD Ultimate for a long time and after a lot of testing on leankernel 2.4, I find it completely redundant.

I'm back to stock (stock launcher too).
It's because I've never had any real problem with stock in the first place. No battery drain, no dropped calls, no sluggish interface and everything works. Then the most important thing is I LOVE the simplicity feel that stock offers so I've decided to go back to stock.
Nothing against custom ROMs.

This is why after you root its always good to Nandroid your stock rom.
The only thing i like about stock is that i know its not going to fail me and i know i dont have to always mess around with tweaks and other things.. it just does what it was meant to do..
Custom roms seems to always have problems with different kernels or maybe the ROM is just in beta.. or a tweak is causing something else to break..
But we also have some good custom roms base off of stock with nothing too much added.. like Android Revolatuion.. No diss towards other roms tho.. just people dont want to always have to change or fix something

It all comes down to personal choices really.
To me i tried AOKP rom with Franco kernel and it really rocked. But then i went back to stock since 4.0.2 with XXKK6 gives me good battery life and its rock stable.. no issues. i do have to give up a lot of customizations but i can live with it. no problem.
The reason i don't want to install custom roms yet is that i would go crazy with flashing roms and it would be addicting so right now i just want to stay away..i would get bored after trying all new roms.. so right now STOCK.. just want to savour the beautiful Galaxy Nexus as is.

I went back to stock on Sunday. I was checking to see if wallet would work on stock but it didn't. When it booted up stock the first time I was like:
http://troll.me/images/snape-dafuq/dafuq-is-this-****.jpg
When I got my phone it was stock for about 5 minutes. AOKP FTW!

Confused. You can run ROMs with the stock kernel. IMHO, stock kernel> any custom kernel. My experience, custom kernels create different problems.
Kernel enthusiasts tend to be a little... too enthusiastic. They tend to ignore the problems and measurebate about supposed battery life or performance.
My best combination is AOKP ROM for the features and stock kernel with a couple performance tweaks in the developer settings.
Now I just go about using my phone to enhance my life rather than the other way round.
YMMV, and it is your life, of course.

I agree 100%.

I never had any issue with AOKP. But I use stock kernel. Custom kernels are for those who can live with a phone not working 100 % and alarm clock fail to ring in the morning. If you want the best of the best for the Gnex, flash AOKP, and nothing else. And don't mess with performance settings.
And btw. The only ROM that ever randomly rebooted on me, was stock ROM. How is that for a laugh?

Stop using Juice Defender. It sucks or it has some serious bugs on Nexus I don't know. Stock everything I had juice defender on and strange things were happening. Touching screen would do nothing, apps would close on their own. When I took it off everything was fine again. Juice defender was recommended to me by someone else. So oh well, seems he was luckier than me running it. Fast forward a week, I got interested in ROM's, now running AOKP with Fugumod kernel and thought hmm maybe give juice defender another shot. Within 1 day I removed it. AGAIN, apps crashing, touches not being recognized, slowness switching screens. I say Juice defender stinks or has lots of bugs. My battery life is just fine with AOKP and Fugumod. Right now my Nexus is perfection. I can quickly get in and out of apps and there is no slowness or anything. I can't see myself ever going back to stock.

I'm running stock 4.0.4 with no issues.

I'm debating going back to stock.
Came from 4.0.2 stock to AOKP 1-30 milestone + franco.
The new ROM is nice and all, but like every 15-30m I get randomly disconnected from the network and takes 15s to reconnect. It's semi-tolerable but I hate things like this.

why was music app missing from AOKP rom Milestone 3? who do you get it back?

no offense meant, but if you are asking this question I would advise holding off on flashing any kernels and get more comfortable with just flashing roms first -- Roms are more pre-packaged and you can build your comfort level by trying out a series of roms prior to messing with the kernel which is a more powerful and inherently more influential element to your phone's operation

Appreciate the input I have flashed many roms but i allways go back to stock, i flashed a kernal earlier but i went back to stock kernal because im scared of burning my processor, not quite sure how safe undervolting and overclocking is, and ya im a noob just got my first android phone about 2 months ago and just rooted it last month.

I haven't tried faux kernel but ktoonzes will be OK left stock processor wise, it won't burn out your processor. Plus you will benefit from his built in tweaks. As far as over clocking/ undervoting ( oc/uv) if you go too far your phone will either freeze up or reboot, so don't use any "set at boot" options until you know your phone will handle it. I use ktoonzes kernel with no oc just the lower frequencies and a mild under volt for battery savings with no ill effects.

thanks for seeing the comment in the way it was intended! seems you have going about things the right way: everyone's phone will accept OC differently, some operate fine at higher levels, others not -- Faux does not post "recommended" levels for this reason, asks that you make adjustments in small increments and use your phone to see how it handles the changes. It is very much a trial and error. I had an older S1 that was wonderfully resilient and would take any setting and still function -- I lost it long before it had a chance to get damaged, My own sense is the phone itself is robust and hard to actually kill -- my earlier caution was more to prevent you jumping in the deep end too soon.
I have tried both Faux and the KT747 kernels, presently running just stock which is in itself a pretty decent kernel.

I tried Ktoonz and it made my playstore act weird and not connect and error out and such.
So I reversed back to my backup image with the rom's initial kernel that was installed with it.
I only find Kernel's being useful for OC or Dual Booting if you need/want the fun with that.
Otherwise find an amazing rom like Serenity or WanamLite or something if you want more customizability
OR a stock rom whichever one suites you better.

Perhaps your voltages and/or settings were too much for your phone to handle. When it gets out of hands, apps will FC a lot and phone will usually freeze or reboot. If you didn't edit the settings, I don't think the kernel left at default settings would affect the Playstore's connection.
