So my apologies for asking this question. What i am looking to do though is improve over all experience for my brother with his phone. Ideally and this is me talking in reference to what i have seen in the Fascinate community. I want a good daily driver that is going to improve over all performance and have the ability to over clock and under volt possibly a different radio as well. I see the Tiamat Kernel but correct me if i am wrong that is only for AOSP roms. I personally love the idea of AOSP but for my brother the phone giving issue in any way is not a option. Again based off the Fascinate Dev community i know our touchwiz based roms in comparison to the AOSP stuff is much more manageable in case anything arises. I only hope that somebody in the community here who reads this is familiar with the Fascinate and can better help my decision. Thank you in advance.
Edit** Just noticed that nitsuj17 is a dev here so hopefully he can chime in. His roms on the fascinate were perfect for daily driving and stability.
Most of the Sense ROM's don't need to be overclocked and undervolted. Most of my favorite have custom kernals modded for the ROM. I've tried overclocking, but it seems to work better with the kernal that comes with it.
AOSP, i enjoy overclocking and undervolting. However, i think testing is the most important thing.
Drellisdee has the best kernel for sense #21 IMO. Nitsuj "m" Rom is an amazing stock modded Rom.. I received excellent battery with that kernel and Rom... Then I always OC/UV to 1.3Ghz and -50mv on all voltages with that kernel

Awesome appreciate it guys. Did all the work tonight and did what faehsemc said. Man downgrading to 2.3.3 was a pain.Only issue i am having now is i can't get android wifi tether to work is this a known problem of sorts? The devices trying to connect continue to try to get a ip address.
I haven't had any issues with tether.. I use wireless tether 2.0.7

ahhhh i was trying to use one of the beta builds. i will try to do that before my brother leaves. thank you again.
I use what is in my sig at stock clock speeds with smartassv2 gov and UV -100 across the board. My phone takes UV like its nothing but if I OC over about 1.3 or 1.4 it locks up within 5 min.
I would like to say that i did undervolt it. No offense to the developer of incredicontrol but it could use a better GUI. Correct me if i am wrong though but you have to use incredicontrol in conjunction with something like voltage control. I figured voltage control would have done the overclocking and voltage setting but it will only do the overclocking, governor, and scheduler stuff. I think setcpu does it all but given that it is my brothers phone i didn't purchase the app. Like i said though the only issue i was having was wi fi tether. So as someone mentioned above he was using the 2.xx version versus the 3.xx betas. If someone can confirm whether or not which version of wifi tether is broken or not i would greatly appreciate it. I don't want to clutter the forum with another thread.

now keep in mind i am the noobest of noobs in modifying phones. i have an Epic 4g and haven't even touched the surface on it's potential apparently from reading through this forum.
my question is (before i start doing anything else to my phone) what exactly does a custom kernel do for your phone?
also what exactly does a custom rom do for your phone?
I am currently running a rooted Epic 4g w/cwm and i am on the DK28 build.
what else does everyone reccomend for me to get the full experience from my phone? (in the way of a custom kernel and custom rom, since i am pretty affluent to most apps at the moment)
Well a custom rom is usually optimized for speed and responsivenes. All roms are different since devs usually put there own mods and thems in. Some are completely stock temed others are themed fully. Depends on what your tastes are. As for kernals they're usually overclocked and undervolted which means it'll be overclocked to 1.2 or 1.3 ghz and run at the same power level as 1ghz or less. Usually gives faster phone with beter response and overall speed. (Opens apps quicker) hope this gives a little insight. I'm personally running epic experience 2.0.07 and genocide kernal overclocked to 1.2 ghz.(not undervolted at 1.2 ghz only at 1ghz so battery suffers a bit). Waiting for next epic experience release.

that does help tremendously! i had most of it figured out but i wanted to be sure as to what they meant. i appreciate the help and i will be trying the rom and kernel you suggested!
No problem man.

I know this is a really noob question, but what is a kernel? I see them all over the developer section when i look for roms, but i have no clue what it is (sorry if this is a bumped thread).
I also wanna know cuz i would like to use the right kernel to my incredible....
Sent from my Incredible using XDA App
A kernel is the bridge between the hardware (for example processor, memory, nand) and the software (the ROM). This is why changing the kernel can have such a huge impact on battery or speed. For example, one kernel can tell the processor to work its butt off, which decreases battery, while another will tell the processor to relax, increasing the battery life but decreasing speed. Since every processor is made from different silicon, not every kernel fits all phones.
Also, in kernels another important thing is the task scheduler. The Brain **** Scheduler (BFS) basically has ups and downs in performance but the Completely Fair Schedulare (CFS) is pretty much consistent in performance. It's hard to explain. I personally prefer BFS over CFS. Also, if you want higher quadrant scores, use BFS.
Hope this helps.
Thank you so much!
AOSP or Sense - it matters to the kernel
Noteworthy when flashing a kernel -
AOSP ROMs require AOSP kernels, Sense requires Sense kernels.
Same story with Froyo or Gingerbread ROMs, either AOSP or Sense.
Bootloops happen when they get mixed.
Great explanation, thanks- I was too embarrassed to ask, so I used the search...and here it was! finally I have a clue

On the piggy website, I'm unclear which kernel is for my incredible?
The kernels meant for the incredible have "-inc-" in their title. I believe the most recent ones end with "-041011".
holy crap there a lot of choices. Any guidance? I don't see anything listing descriptions of anything.
This would likely suit you best:
http://www.ziggy471.com/2011/04/10/beta-kernels-10-apr-11/
Ztest-INC-BFS-HAVS-041011
has brain f*ck scheduler and HAVS for custom voltage set. note this is his latest kernel release but it is also labeled beta. So if you have any weird issues with it you may want to check out an earlier release.
-- As always I have to jam in my favorite kernel (chad's incredikernel) if you haven't tried it out yet then I can only suggest that you do.
Cheers

In going back and forth, I've personally found the performance of Chad's 12/23 kernel and Ziggy's 4/10 kernel virtually indistinguishable. Some devices don't respond well to the hybrid adaptive voltage scaling (HAVS) or the settings he's implemented and will be more stable using static voltage scaling (SVS), which is the standard kernel. IncrediControl works on this Gingerbread kernels so I'm assuming it would work well on his Froyo kernels for adjusting the voltage without a script. Any decent clocking app will handle the speed. But the script guide he has is very useful and might be worth playing with if that's your thing. If you have any questions for him, he's best found at infectedrom.com these days.
Wow thanks! I enjoyed scripting on y Eris so I will look at that
Since i have everyone here, is there a stock rom that has all that blistered removed? I can adb shell and remove the stuff but I was just curious.
I'm pretty sure that this question has been posted alot of times but I need help deciding on a decent rom and a kernal which would go with it that has everything working and has the best battery life as well. I will probably get CM7 but idk which kernal will go best with it.
I also need help changing the LCD density of my screen. Before I switched to my EVO I owned a HTC HD2 and had pongsters hyperdroid on it which had lower LCD density allowing everything to be smaller on the phone.
Those are my questions please help. Thank you!

Not exactly sure what you mean by LCD density but I can help with the ROM kernel question.
As far as a ROM goes the best way to find the right one is to do 2 things.
1. Make a list of things you are looking for in a ROM. Stability, 4G, HDMI, Wireless Tether, etc. Then check out ROMs that contain stable versions with those features you emphasize.
2. Get flash happy. Flash a ROM, test it for a few days to a week and then flash another one. If you find yourself coming back to one specific ROM over and over again then that is probably the one you should stick with.
Check out this thread for some ROM ideas: http://forum.xda-developers.com/showthread.php?t=951057
A few ROMs that I didn't see mentioned in there are Myn's Synergy, Salvage-Mod, Sinister, Savaged Zen, and Swag.
As far as kernels go you have to remember a basic rule. Sense ROMs get paired with sense kernels and AOSP ROMs get paired with AOSP kernels. Then you do the same thing you did with the ROMs.
1. Make a list of what you want in a kernel. HAVS, SBC, overclocking, undervolting, etc.
2. Get flash happy and test which kernel matches your ROM the best with what you are looking for.
I know that may not be the exact answer you are looking for. But ROMs and kernels are all about personal preference and daily usage trends. each one has pros and cons that different people may or may not like. Check my ROM/kernel combination. It fits my usage habits, constantly using it at home and barely use it when out of the house, but it may not fit the way you use it. Experiment and have fun.
And here is a thread about kernels: http://forum.xda-developers.com/showthread.php?t=894880
Quite personally, I would suggest MIUI. If you're not into that kind of thing, I would suggest Deck's, who updated to stable yesterday!
Kernel, I would say Tiamat 4.0.8.
Look up Vipermod. Check my signature. Most phones can at least handle a -50 undervolt for the Tiamat mentioned above.
I would suggest the flashable GPS fix in my signature. Locks on quite accurately.
You may have a lot of cell standby drain. Check development section for a thread about Radio wakelock combination.
Best way to change the density would be to edit the build.prop but there are apps in the Market. Just search density changer

Then you will be able to find out what you like.
AOSP is always a winner for me.
Oh, and make sure you Nandroid.
I agree with both posts above, you have to try out roms for yourself since in every rom post you will see someone saying this is the best rom they have ever hadand battery life is super. Your question has been asked a million times before but like that millions of answers that were given it all boils down to personal choice.
I run AOSP with an sbc kernel but Lord knows you may find people here who would dispute the use of an sbc kernel. LCD Density apps are in the market or just use google for help. Sorry this is not a definitive answer but honestly just find a rom you like and give it a shot....
Thanks for all your answers time to get flash happy!

For me the best combo of performance and battery life has been SavagedZen and CM7. Completely transformed my perception of just well the evo should perform. Basically no compromises, Fast AND great battery life.
I'm using MikG 2.56 ROM with Aggressive Freedom kernel. Holding up pretty good.
For me the best combo is Decks Rom 1.3 + SavagedZen Kernel + Vipermod
I can get about 16 hours on MikG 2.56 (stock kernel) with moderate use. Damn near perfect ROM.

Which version of CM7 are you running? I'm on the 219 nightly and it kind of meh. I've tried savaged Zen with CM7.1 and it was good but my battery didn't seem to last as long during use so I decided to move on to other kernels. Are you running any supplementary battery apps?
Merry Christmas everyone! I hope everyone received all the tech goodies we wanted for Xmas!
I've noticed that most of the ROM's available in the development section already have an Overclocked Kernel and also UV options. I personally would rather use a stock kernel, or a custom kernel that is not overclocked. Right now I don't see that available from what I've searched for.
There are a couple ROMs I'm interested in running, but both install a new OC kernel. Is it possible to strip the kernel from the ROM before installing? And if so, does anyone know a tutorial for doing so, or is it as simple as opening the archive file, stripping the kernel out, and rezipping the file?
I know there are apps like SetCPU to change the clock speed on an OC ROM, but I really don't want to depend on software to keep the OC from occuring. I hope I was clear enough in my post to get the point across lol! Thanks for any assistance gents (and ladies).
Franco's kernels don't have OC

Thanks Josh! Appreciate your input. I am still interested in the other option as well, stripping the kernel from the ROM.
I am not sure how to repackage the from after you do that, but if you extract the rom the kernel is called "boot.img" and you can flash it in fastboot so you can basically flash any kernel you want on any rom

Just curious why you wouldn't want an OC/UV kernel, you're getting better performance and better battery life, no downside imo.

I honestly just don't like to OC my CPU's. In the long run it will decrease the life of the CPU.
Besides, if you have a great AOSP ROM to run, there really is no need to OC at all. Any performance boost from the OC comes at the cost of shortening the life of the CPU.

I've run Intel chips at 40% OC for a decade at a time, with little impact.
I don't expect my Nexus, with or without <20% OC, to last me nearly that long.
Just sayin'....
