Hey,
So sorry for what probably seems like a dumb question. I'm usually a Vibrant guy, but I'm helping a buddy out with a G2/looking at the feasibility of getting one myself. I know at least for the Vibrant our normal kernels don't play nice with our version of CyanogenMod 7. I was curious if the same held true here? Or can I flash any kernel? Also, I see that there are different types based on the type of ROM, which is a new thing to a Vibrant owner. So can anyone recommend me a kernel? I'm pretty decent on flashing and all that, and recovering a brick (at least with my Vibrant). Basically I want the best bottom-line performance. I don't need extra bells and whistles, just a nice high clock frequency. Thanks!

If you're looking for a kernel for CM7, the kernel included is quite snappy though I personally run pershoot's kernel as he undervolts and has some other tweaks which improves responsiveness *and* battery life, at least for me.

CM7 already comes with its own custom kernel (which also supports some overclocking), so no need to flash a separate kernel if you don't want to. But as already mentioned, pershoot's works well too.
You can't flash any kernel. Some are Sense specific, and some are for non-Sense ROMs. Flashing the wrong one for your ROM can apparently brick the phone, so read thru the threads for the ROM and kernel you are interested in, to be sure. The ROM developer will usually have kernel recommendations, or you can see what kernels users of that ROM have tried.
Like stated above you will need to read the instructions and notes on the kernel thread. CM7 has special requirements. Other Roms don't need. but be very careful on what you flash!
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?
HI, i am new to this coming from iPhone..i have the AOKP rom for my atnt galaxy s3. I am wondering what is the deal with kernels? like what is the use of them? i am guessing the rom comes with it, but should i load the kernal like this one here:

Kernals can change how the phone performs severely as well as add features. They can also affect battery life, speed, and how smooth your phone is.

so for example since i am running the AOSP ICS rom, and there is AOSP kernel available for download, so i get that? and what is the order of installation? since i already have the rom installed and been using it
I suggest you stick to the kernel the rom's include until you understand fully what it is.
So to add to this, I learned many ROMs include a kernel. We don't always have to go out, install a ROM and a Kernel. In most cases it is if someone made some custom tweaks to a ROM kernel or stock kernel that you would reflash it. Please correct me if I'm wrong, still reading and learning.
To use a car analogy, I think of the phone hardware as the mechanical parts of the car, the ROM as the electrical system in a car and the kernel is the computer taking all the signals from the electrical system and telling the hardware what to do. Rooted ROMs can take advantage of connections already built into the phone but maybe turned off or disconnected in a stock ROM. Non-stock kernels can direct the traffic of electrical signals (like a stop light), change those signals, modify what hardware those signals control or even how the hardware behaves for a given signal. It may be a bit simplistic, but the best way I can explain it. A touch-wiz ROM and AOSP ROM will have different electrical connections, so they must have kernels made for those connections.
okay so I have been hearing a lot about kernels lately and while I am no noob (some might disagree with this sort of question) but I would like a rock solid definition of what a KERNEL is. I understand them to be the essential backbone files of a rom. What prompted the question is that i have been reading a lot about battery life and how different kernels affect battery life etc. so how is it that the kernel actually works with the rom?
thanks so much

Heres a good link to learn about kernels
Kernel info
The best way i seen it put was, think of the kernel as the engine and the rom as the body of the car. The body of the car (rom) just makes the car look nice and user friendly. Now when we talk about the engine (kernel) simply put red lining the engine will get you to go fast but burn gas. Keeping the rev down low will make you run slower but saving lots of gas. Thats just one way to look at it, rpms being the cpu anyways.
Dont know if that helps you, thats just hoe i first understood it
Another handy link about Kernels... http://www.androidcentral.com/android-z-what-kernel
Hi!
Do you know what ROM is the fastest (with better performance) for our Nexus? I don't care if it is Stock or Custom, all I want is the better performance/battery life rom possible.
I am now with CM11 unoficial by playfulgod and I like it because it is 4.4, but the phone takes too long to open the apps and lags a little bit in fast transactions....
EDIT: I also don't care about the version, 4.4, 4.3, 4.2, 4.1, anything... the changes are minimal from 4.1 to 4.3 and 4.4 has its pros and cons
Flash and find out. Thats your best option.
Edit: Wrong section. Sorry. How the h*ll did i end up in Galaxy Nexus section.
I'm using CM official nightlies and find it quite good. I found 4.3 faster but like others have said it's a case of trying different rom / kernel combinations. What works well for me night not be much good for you and vice versa. A lot of different factors come into play. Apps used, background apps etc.

YOU ARE POINTING HIM TO A NEXUS 4 ROM! :banghead:

all roms give the fastest and good performance.. its all depend on you.
so far after 1 week experiments.
i use gnex + extended battery + slimkat 4.4.1 + A.S.K.P kernel + odexed + run perfomance scripts + tweak build prop = superb. already 4 hour screen on... with over 50% balance battery..
galaxy nexus i9250
I have just flashed Gummy's 4.4 rom just trying it out from BelieveRom. I was looking for something faster with some of the new features and this had most of them. Real smooth so far with steady battery use on stock kernel. Will try some other kernels to see if it will add the butter.
I'm running swordrune10's cm11 its pretty good

Care to lay out all the tweaked build prop, performance scripts? How big is this extended battery? Is it the one from Verizon that Samsung made or is it one of those big 3,000+ sized ones that makes the phone super thick? seeing 4 hours of screen on time and only half battery used seems too good to be true.
thanks guys!
I will try a few roms here and give you the feedback later
The performance were only good on 4.1.2

im use the super big extended battery.. 4000 mah.. its big but worth it.
i dont like to use power bank as alternative.
im using pure performance™ scripts.. but carefull in scripting, it may cause overwrite the existing build.prop.
additional of using performance control. apk> download from fdroid repo. its seem to be easy to use for tweaking ram performance. especially for noob likes me.
sorry for my bad english..
galaxy nexus i9250
Thats pretty nice. It seems way big for me though. I'm not a make the phones a slim as you can kind of person, but i do like a happy medium.
Vanir is pretty smooth and fast. Battery isn't greatest but performance kicks ass on my toro. 4.4 flies but still has black boxes
Yes, Vanir is very smooth. But the most important is to install custom kernel. For now the best are ASKP and Mpokang SuperRAM. If you install one of these kernels, i think every ROM will be smooth.
I suggest to try MetalOmni - very fast 4.4 ROM.
ITS ALL YOUR OPINION. FLASH AND FIND OUT. These threads arent even allowed. And on top of that: how would you feel if you had put alot of effort into making a ROM and people dont like it because its "slow". Just try and find out seriously. Youre maybe the 100th with this thread. This will probably be closed in a couple of days.

well, then I will have to flash all the roms there are to see for myself which one is the best in terms of speed. considering that there are at least 5 different roms just for 4.4 and for 4.3 (and previous) there are much more roms... I would need to flash about 20 roms (or more) and test them at least a day or two to see which ones are better... By my calculations, I will need at least 1 month. Considering that android isn't my life, I have many other things more important to do, I will spend more than a month doing that testing thing...
So, do you really think I can test them all for myself? Shouldn't I ask here for names of the best roms in terms of speed that many members have tested? This way I will only test the 3/4 most mentioned, not the all 20. I know that the developers do a lot of work in their roms, but there are ones better than others for many things, I don't think the developer of rom X would mind if I prefer the rom Y from other developer because it is faster. Maybe the rom X has more options and other things, but lacks in speed, so the developer of rom X isn't interested in making a rom for speed, it isn't inferior to the other rom, just different.
If this thread is locked, even finding it unfair and kind of stupid, I don't really care. I already got a few opinions and I'm testing some roms here. Thanks a lot for the ones who helped me and aswered this thread.

Well, you got me curious.
I am currently testing SlimKat ROM and it looks fast enough for me.
Unfortunaly, it's still on beta (4.4 KitKat), so you might expect a few bugs.
Still, it's a good ROM, in my opinion.
