I'm using CM7.0.3 as my rom and my kernel is the default cyanogen one.
Good enalogy by Xandermpls. Kernels set the boundries of what your processor speed is

The built-in CM kernel is really good.
If you're not having issues, there's no need to switch around with kernels. Some different kernels claim better battery life, better performance, etc. but I'd say the buil-in CM7 is really solid as far as stock kernels go.
Its kind of like radios, CPU profiles, etc.. Everyone's got a different one that works "best" for them.
I believe the kernel is like an interface between the hardware with the software, which is why incompatible/development-stage kernels have broken WiFi, bluetooth, etc. It's also why different kernels allow for different CPU controls - voltage, speed, governors, etc. Some kernels also have memory management tweaks, among many other things. I personally stick with the stock CM7 kernel as it has never given me anything but great performance and good battery life, but if I were to try a different AOSP kernel I would only trust pershoots.
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 everyone, my Incredible 2 just arrived and I'm about ready to root it and flash a ROM. I first wanted to try the CM7 stable build because they're "official" developers in my opinion, but I read some posts and there seems to be some issues with various small things. I looked at the nightlies and those still seem to have issues as well. Then I looked over here at the CM7Kangs, but something seems to tell me that CM isn't completely stable in itself. Whether it does or doesn't have Sense, etc. I'm just interested in a new ROM that is stable and fully functional (cameras work, GPS works, etc). The main reason for flashing a new ROM is because I don't want all the bloatware that comes with this thing, and even if it isn't cutting edge, I'm sure it can be faster than stock. Any suggestions guys?
EDIT: I hear Skyraider Zeus/MIUI are good. I found Skyraider Zeus 1.3 on the internet, but what versions of MIUI are stable? I hear this ROM has good reviews too
http://roms.miui.us/ 1.12.9 is stable an totally functional works good with areoevans .7 bfs kernel

This is skyraiders link which is a top notch sense rom.
Skyraider's roms are top notch. All the current cm7 kangs work without flaws. Miui12.9 is awesome. Also look into condemned sense rom, any of nits work, alot of people are running mikrunny 3.5
Sent from my Incredible 2 using xda premium
Thanks! Just wondering, is Skyraider Zeus overclockable? I looked at the post and the only kernel it mentions is the "HTC OTA update". IIRC, you need a special kernel to OC, don't you?
Also, my question above is the same for the MIUI 1.12.9 ROM. Can it be OC'd? is it fully stable on the non-aeroevan kernel?
Yes you can us dres kernel found in development forum for skyraiders and miui I recommend using areovans kernel due to stock kernel can cause a few issues (low in call volume and for some data is not reliable)
Sent from my Incredible 2 using xda premium
another vote for SkyRaider Zeus. if you want a ROM you can set and forget, this is it. everything works, except for Verizon's wifi tether in the "quick launch", but that's it. it's just as reliable as stock or better, has tons of features and extras built in. a lot of thought, and time went into this, it is truly a complete Sense ROM.
never tried AOSP ROMs so i can't comment.
good luck in your search. at least try Zeus, you won't be disappointed.
I personally haven't tried miui so I wont comment on that. There are plenty of great roms out there. I am currently using the latest cm7 nightly as my DD (#134 I think?) with excellent results! I cant remember seeing any issues since i flashed it. I am going on nearly a month with zero issues. Before this rom I tried out New To Root's Incredible 2 HD RLS v1.1 which was also a flawless rom from my experience. I had no luck with the RC releases of cm7 but I know of others who love them.
I like to run sense from time to time but I always go back to aosp for the customization possibilities it offers.
In the end, none of us can tell you what the best rom for you is. I can say that in general if you want a rom that you can flash and forget about it you will probably want to go with a rom that has been around for a while, preferably one that is in RC or Final status.
My advice is to try a few so you can see whether you like miui, aosp, or sence. Once you figure that out then just try a few of that type to find one that suits you.

Well I've never even used a smartphone before other than when occasionally using my brother's iPhone 4, so the interface won't be a big deal. I'll adapt and enjoy whatever I end up using. I just want to use something that's stable (in the sense that it's fully featured and nothing randomly messes up) and fast. Skyraider Zeus and the various CM7 kangs seem to accomplish this. I'll have to think harder on which one i want to use. The CM7 kang i'm looked at is by Condemned Soul. I can't really post in that forum yet, so I'm using this thread as a way to get this type of information.
The CM7 kang that he made is already able to OC I believe because of the CM kernel...so that's a plus because I'd really just want to flash the phone and enjoy using it. I like tinkering with stuff, but I don't want to constantly worry about flashing/unflashing and causing instability. I need this phone to last until the next upgrade. The thing is, "Sense" seems really interesting. People say it looks nice and has lots of features, but I've never really experienced these features anyway, so maybe I should go with CM7.
I always hear people talking about how stable MIUI is, but that has not been my experience with MIUI at all. I have tried MIUI three or four times on a few different android devices each time following the install instructions exactly. Wiped factory reset, dalvik, permissions battery stats etc. all the default ROM install stuff.
Each time MIUI boots up fine and works well for about 3 hours and then randomly reboots and glitches forcing me come back to the stable CM7 version.
I really want to like MIUI, but my experiences seem to be very different than most people.
Interestingly enough, when I googled the word "issues" on Cyanogenmod's stable forum, they mentioned stuff about Skype having problems with audio that was fixed in the non-stable nightly #134. This is why I am wondering if CM7 is truly stable or not. I'm not sure how to track errors/issues, so I don't know what the nightlies have improved upon, and I definitely don't know what the kangs improve on/fix.
If you like tinkering with stuff I'd say you could go the CM or MIUI (AOSP) route. But this phone is not going to be as good as other phones that are running aosp. It was made to run sense.
Fully featured is also going to set you back, do you mean fully featured as in being able to use it as a world phone? GSM Capabilities?
If so you're going to have to run stock or close to stock.
Me personally, I like sense. MikRunny 1.01 here. Fast, stable and everything works. Except for GSM though.
cstone1991 had it right though, you have to run them to see which one you like best. Everyone is going to have their own opinions on which ROM runs best and again each phone is going to run ROMS differently as well.
For ROM's you're going to basically go through different bases like this.
AOSP ROM's like CM7, MIUI
Sense 2.1 ROM's like Andybones stock or skyraider zeus
Sense 3.0 ROM's like Virtuous
Sense 3.5 ROM's like MikRunny
Each base has different features, different feel. You'll also have the ability to theme them differently as well.
Try the ones that interest you the most, run them for a few days each and see which one fits you the best.

I like tinkering with stuff, but only to a point. I don't like to constantly have to "re-do" things that don't have to do with the tinkering process (IE: Flashing over and over). What makes the phone able to run "Sense" instead of AOSP? I'm not aware of the whole Sense vs AOSP bit. If I could get some solid info on why I should run Sense instead of AOSP, I'll run Skyraider Zeus most likely, etc.

What I mean is that I don't need "extra" features or anything like that. I just want the phone to work the way it's supposed to....such as GPS and the camera(s) working. I don't want to have to sacrifice something I use often in order to gain speed. World capabilities aren't a big deal to me for sure. I don't know what "tethering" is so that whole bit isn't too important either.

Thanks for this huge list. What's the difference between Sense 3.5 vs 3.0 vs 2.1? Yes, the obvious answer is that one is newer than the other. I heard Sense 3.5 has issues with the camera being upside down, etc. So I'd probably stick with the Sense that came with this phone (Sense 2.1 probably)

The drivers are mostly what's different. Because HTC uses sense originally, Sense is going to be what works the best. It's not that it can't run AOSP but that sense is going to run without problems because that's what it was made to run.

All the features work in most ROM's like that. Some ROM's (Mostly AOSP) have issues where the camera is stretched (front facing cam on miui). You're not really losing anything on other ROM's it's just that they work differently.

Sense 2.1 has the older stuff, it's probably going to be the fastest out of the rest of them because it has the least amount of stuff in it. This is what comes on the phone stock and what Skyraider runs.
Sense 3.0 incorporated new features like a new lock screen, new weather app, weather animations, sounds, display features, dial pad, messaging. It's running more stuff so in order to run correctly you would have to use a rom that's optimized.
Sense 3.5 is the newest and also has different features but it's very close to 3.0. Just about everything is the same that you can see but there are differences behind the scenes. Also there are no camera issues unless someone puts out a ROM that was quickly thrown together.

I say you skip 3.0 altogether and run either 2.1 or 3.5. Anything is better than stock with all the bloat so try skyraider or andybonesstock.
If you wanna try 3.5 go with MikRunny 1.01 and in the display turn off the 3d widget features. See how that runs on your phone, It's flawless on mine, I get no lag but again different phones run differently.
Alright I've decided to go with Skyraider Zeus thanks to reading all of this. Thanks for all of the help. I don't plan on flashing a new kernel onto Skyraider Zeus, so whether the stock SZ kernel can OC or not doesn't matter to me.

I don't think you will need to over clock. I haven't needed to on this phone. I have tested it and all it did for me was reduce battery life and improve benchmark scores. I haven't been able to tell a difference in actual usage whether I run at 1ghz or 1.8ghz so I opt for better battery life. The only rom that I benefitted from overclocking on was one of the really early ICS builds.

To all you who responded and to the OP - thanks!
This thread has been very helpful, I just got my Inc 2 last week and looking forward to trying out some new ROMS.
I've read that the stock kernel changed with the OTA updates (I'm on 2.3.4)
Does that limit which of the ROMs I can run?
Are there better ROM managers than others when it comes to this phone and the ROMs available for it?
Thanks.

The fact that you're on 2.3.4 means you need to use a downgrade tool and go down to 2.3.3. Then you'll use software called "Revolutionary" to get root, etc. If you search for "nat3mills" on youtube, and look under his videos for incredible 2 stuff, he has step by step tutorials on how to do all of this. That's what I'm going to do. Hopefully XDA doesn't penalize me for referencing this youtube user. Good luck!
EDIT: Also I'd like to ask everyone, since you feel there is no point in overclocking, is there a way to undervolt with any of these ROMs? Specifically SkyRaider Zeus/CM7 (asking because these seem to be the two common choices for people, and I figured this thread could now be used as a good reference) My logic behind undervolting is that if you can overclock it drastically on stock voltage (which is what I assume SRZ and CM7 are on) then you can probably keep it at stock clocks and undervolt it for better battery life/temperatures.
EDIT #2: Ok I was just looking in CondemnedSoul's CM7Kang thread. Apparently there is an app called Incredicontrol that let's you mess with voltages. Just to make sure, CM7 in itself only has the ability to control clock speeds (under/overclock) and not voltages, right? This means that Incredicontrol is necessary to mess with voltages?
from my understanding; if you OC and UV you gain nothing, if you UC and UV you conserve battery, if you OC and OV you make your device faster but perhaps introduce instability.
i've been reading tons of threads, clock speeds and volting included, and i have made the decision to not O/UC nor O/UV because my phone works great as it is and i do not care about benchmarks and my battery life is acceptable as it is.
if you really want to know more, set aside some time (hours) to search and read thread after thread on these topics and make your own educated decision based on the debates other members have participated in.

Uhhh, you're looking at things the wrong way completely. Having less voltage whether something is overclocked or underclocked is ALWAYS better. If you increase the clock speed and have the voltage less than stock, it's a complete WIN WIN situation unless it introduces instability, but this is something you test for. Some people Overvolt to Overclock even further, but increasing voltage is not ALWAYS necessary. Keeping speeds at stock, but UNDERVOLTING helps battery life. Finally, overclocking but keeping stock voltage is the best combination for actual speed. Increasing voltage reduces battery life much more than simply increasing clockspeed.
This is how things work for desktops, and I'm sure it applies to everything else, including phones.

Not necessarily...desktops and laptops and phones (hardware in particular) is built to run within certain voltage limits. Undervolting CAN help but not in all situations, and especially when running at max-min frequency can cause major instability in a speed-step cycle.
It is usually safe to undervolt a little bit with most hardware - but radios in general can be affected by voltage. Test all hardware with stress testing to ensure it is safe FOR YOUR PARTICULAR PHONE.
Background : MS in Computer Science (Heavy Unix Background)
To keep the thread on track - this phone was meant to run with Sense 2.1 - if you sync multiple email accounts or run many apps (buggy or not) you should probably stick with Sense 2.1. If you arent a demanding mobile phone user try anything else. I wish the AOSP builds were more compatible with HTC - and if AOSP isnt integrated into any HTC phones in the future I may switch to another manufacturer.
Are there any advantages/disadvantages for using a stock kernel vs a custom kernel? Thanks for the responses.
Sent from my Modded Classic Evo... It's easier this way.
Stock kernel usually does'nt clock over 998MHz and you are'nt able to over or undervolt the kernel for better battery life.Also on custom kernels there are more governor options(smartass,etc.).Custom kernels can go up to 1118MHz sometimes higher,depends on the CPU.

I am aware of those differences. Basically, I'm wondering why I see so many people wanting to use a stock kernel (especially the one in the new OTA) and I was wondering why. Like what are the advantages of using the stock kernel over a custom kernel? Is it more stable? Are there any other things I may not be thinking of that would make a stock kernel a better choice? Thx again!
Sent from my Modded Classic Evo... It's easier this way.
I would think stock kernels to be smoother because they are designed for that particular rom/build,when a custom kernel is designed to run on different roms/builds,then when roms are updated or changed,the custom kernel does'nt,unless changed by the developer,hence the lag and FC's.I hope thats the answer you were looking for.
Custom kernels are made universal for several devices and roms. Although they yield benefits over stock, sometimes they can be unstable on certain setups. like mentioned above stock is made specifically for said device bout somewhat limited, though very stable
