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.

[Q] htc evo overclocking

Is there a good solid kernel I can use to overclock my urevoked forever rooted evo. I've done a lot of searching and can't seem one that let's you use wimax WiFi or the camera. Help Is much appreciated.

Why not ask your question in the actual Q&A section?
http://forum.xda-developers.com/forumdisplay.php?f=652

I just use SetCPU on stock and use their perflock disabler. Its a little harder to configure for actual overclocking, but if you need to do any underclocking, you disable the perflock after every boot and have profiles set up. You could probably find the right settings to do overclock too, at least, I think you can.

Sorry I posted in the wrong spot. Newbie but tryin hard here. Finally rooted froyo and trying to make the best of it. When I try to disable it tells me wrong kernel. I had it oc'd yesterday but all sensors and camera were disabled. so I reflashed my original rom. I'm looking for a stable kernel that allows OC and is fully functional on my froyo Rom

I'm using the netarchy kernel 2.6.32 (bfs version). Everything is stable and fast overclocked to 1.15. I'm not sure how stable it is beyond that point. I tried 1.267 (cranked it all the way up), but that was definitely too much.

Thanks. I'm now running solid and stable at 2.22 ghz with all features of Evo working perfect. snappy!

i hope you meabn 1.22ghz

Yeah, 2.22 would probably blow up the phone! lol. Seriously though, it gets pretty hot when overclocking at 1.2 GHz, Can't imagine going too much higher without having serious damage occur.

Yeah I meant 1.23. I haven't ever had any heat issues yet. BAttery last longer too with my current profile setup. Amazing.

[REQ] Stock Rom that allows us to keep root

Im looking for a stock rom with no changes to it that allows me to keep root. I Looked through all the older threads in development but it seems there have been updates and such. Right now I am running CM 6.1 and it seem my batt is dying way faster then it did on a stock rom. I'd like to compare them and such. If anyone has one or can point me in the right direction i'd be happy! Thank you!

Yes, I am experiencing higher drain as well. Search the development section for cr_mod, look for the CR_Mod OTA 1.35.something. It's the rooted stock ROM with a wireless tether built in, OTA update and all. That's what your looking for. I flashed dumfuq's OC 4.0 kernel over the stock ROM and got better battery life than the stock HTC kernel, so I also recommend doing that. I'm on cm6.1 stable now, so I can easily modify themes, since it's AOSP based, and also so I can use the gingerbread latin_IME keyboard, since you need at least froyo to do that.

Hey thanks! I went back for about 8 hours and hated it. Im back on CM 6.1 and im getting terrible battery life still. IDK, I am going to try and reformat my SD card and reflash at a full battary etc. I migh ttry the kernel, but, I really don't want any OC of any kind, just maybe a lower standby setting, something in the range of 50mhz while the screen is off or something.

I cant see how formating an sd card could help. Anywho, cm 6.1 has the oc kernal already built into it. You dont need to flash any kernals, just use setcpu to adjust the speed.

50 MHz is too low. 245 is the lowest option

I said try flashing dumfuq 4.0 over it because I THINK, not positive, but I was speculating that cyanogen had modified the kernel slightly that was causing a battery drain issue, because I stopped having so many issues with it when I flashed dumfuq's 4.0 kernel over it. Sounds weird, but it helped. I still have an occasional glitch where something is holding a wakelock on the system and it won't go to sleep, which is really annoying, and I think I traced it back to the music app, but still not sure there. I've been off of the charger for over an hour, with just 11 minutes of screen on and screen is 71% of the usage while cell standby is 11%, that's what makes me think flashing dumfuqs 4.0 fixed it. Cyanogen must've made a modification.
So, also @ the OP, go into spare parts battery history and see what is using it. If "running" is up above like 30 or 50% then you have something holding a wakelock, go to partial wake usage, and look at the app or UID that's got the wakelock. Rebooting normally gets rid of the lock for me, like I said, haven't quite figured it out yet.

Alternate Kernel recommendations for CM 7.1

Hello there,
So as the title says, does anyone have some Kernel recommendations me?
As you probably know I'm running on CM 7.1 stable with 12.54.60.25U_26.09.04.11_M2 radio if that even matters, and the default kernel which comes with CM 7.1.
I've seen a lot of people around here use LorDModUE kernel. I don't exactly know much about kernels so I have no idea how one kernel would perform in comparison to another or even how it would effect the functionality of the phone in general.
So what made you want to change your kernel in terms of performance and features? Which features stood out to you most and why?
Thanks a lot for any help on this matter!
Cheers

No one can help me out with this topic here?

I used Lordmod Kernal 8.5 BFS when i used CM7.1
hope this helps

It's your phone, your expectations, your needs, your time.
Backup, flash, test.
Didn't like it? Restore backup.
Wanna try another? Flash again, test.
It's fun, you will see.

Some people experience issues with a bfs kernel where their internet will stop working after a while until they toggle their connection on and off. Installing a cfs kernel will fix this. If you have no issues though and have all the options you want, then their is no need to change it unless you just want to test out other ones. As stated, some prefer one over another.

Hmm yes I do like messing with my phone haha, though I only have one so it's my main phone. Can't be having too much fun just in case it decides to give me lemons .
Does flashing Kernel require wiping data? I guess that's not such a big problem since I have TB to help me out in that department but it would save a lot of trouble if one did not have to wipe data every single time.
Cheers

Oh that would suck wouldn't it? I've heard BFS > CFS right? Does it really make a noticeable difference? I was going to go try out BFS anyway since it sounded a bit more interesting.

Thanks for this! Glad to know it's CM7.1 friendly.
EDIT: Sorry for the double-post! Thought it would automatically combine like I've previously experienced, guess not.

Yup... That's about right.. LordMod 8.5 BFS pretty much gave me the best performance out of the ones that I tested while on CM 7.1
And yes.. although I haven't experience a very significant difference.. BFS is a performance enhancement over CFS according to LordClockan.. He's the kernel guru so I believe him!

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.
