[Q] Sprint Lover's Rom..Best Kernal for it?

Hey all,
I just flashed Sprint Lover's ROM and I was wondering what is the best Kernal for this Sense ROM? I really like the stock look, but I would love to improve some performance under the hood.
Any help would be great!
Thank you very much!!!

I always use Netarchy's kernel, but what may be good on one phone may also be bad on another phone. I suggest flashing different kernels and testing them out.

Go Here for his kernels. I use Netarchy Toastmod - 4.3-cfs-havs-more-sbc and so far it's worked amazing on the various ROMs I've used (including Sprint Lovers) but it's worked best for me on Myn's ROMs.

I think I'm gonna flash this kernel tomorrow, but maybe the nosbc so I don't fry my battery... Have you had any issues with the battery with the sbc? And do you use SetCpu with the kernel?

No, and no
Don't use SetCPU with a havs kernel. If you go with one of his nohavs kernels then by all means use SetCPU as you wish. Another thing, just from my personal experience (though it may be different for your phone) the CFS kernels work far better than the BFS kernels. There's a guide around here that explains the difference.
As far as SBC goes, I haven't had any issues yet. I've been using a battery monitor to watch what's going on with my battery and haven't seen anything wrong with it. Another thing I do, just as a small precaution, is not let the phone charge 6-8 hours over-night. I'll let it charge to 100% then let it sit for about 2-3 more hours and call it quits. Don't know if that really does anything, but it makes me feel better so eh.
I know the military (I'm in the Army) uses Lit-ion batteries and trickle charges them without having any of them blow up/fry, however they do lose their ability to hold a charge over time. The fact that they do it, and the only problem has been lifespan of the battery is what convinced me to try an SBC kernel. Just choose whichever you feel comfortable with. It's all preference really.

Netarchy Toastmod - 4.3-cfs-havs-more-sbc is the best from my personal experieince...good battery life and makes choppy roms run a lot more smoothly

I've been using that one with no-sbc and it's worked great with the conservative profile. HAVS just deals with what voltage the processor uses at any given time/frequency so you can indeed use setcpu with it. It's the kernels with the built in smartass governor or ROMs using other battery tweaking scripts that don't always work well with setcpu.
And trust me, the military does not trickle charge their li-ions and they only run them at 4.10 volts to extend their life (depending on battery, always less than volts than their commercial counterparts). This I know for certain.

Anyone have a link to the stock kernel
Sent from my PC36100 using XDA App

Guys quick question, with the above mentioned kernel. What frequency does if use when you turn off the screen? I want if to use the lowest possible, does the kernel do it automatically or should I use something like the overlook widget?
Also, can someone please provide instructions how to update the kernel, I haven't looked at the link yet so If there's instructions there that fine.
Thanks

wifi errors
i just flashed to netarchy kernel to my evo. cfs, havs no sbc. when i try to connect to wifi it says error. i used kernal manager to flash the kernal. is there anything i can to do to get the wifi back or do i need to go back to the stock kernel. i am running sprint lovers ROM. any suggestions.

update. when i flashed manually everything worked fine. maybe the kernel manager program has an issue with wiping the cache. not really sure. just thought i should let everyone know.

I would use the stock #15 HTC Kernel but with SBC. Link is in sec post here..
http://forum.xda-developers.com/showthread.php?t=876590

I've been using netarchy 4.3.4 cfs more havs aggressive sbc with no problems. Amazing battery life and very responsive.

Netarchy's kernels are very stable,if you're up for it try a sbc kernel,great battery life.

sbc
i was just reluctant to try an sbc because of the horror stories i have heard about frying the battery. i guess when i feel lucky i will try it.

[Q] what is a kernel?

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

Help with FPS and scrolling laginess, TIPS?

Hello all. I wanted to see if tips could be posted on how to increase scrolling laginess and increase fps in things like video and games. I bought my wife the shift and Ive noticed its alot better at mobile gaiming and video playback/recording.
Ive rooted and installed myns warm two point two along with netarchy-toastmod 4.3.4 cfs havs more nosbc.
Ive overclocked to 1.2ghz using setcpu and left the governor on smartass. (no profiles)
These seem to have made a visual improvement, but I want/need more.
So my questionis are...
Is there specific kernels that will help get the results Im looking for? (Im more insterested in performace, but would like batterly life is possible)
Are there any hidden tips that can be done via command line etc that will change things to allow for a better fps performance?
ANy help, links, etc will be appreciated. Ive been searching for weeks already just to get myself rooted/romed/kerneled.

The Shift has a better processor and a better GPU. I don't think you're going to be able to match it by overclocking. There are ROMs that tend to be a little smoother than others (MikFroyo 4.6 is nice), but there's only so much that can be done with the hardware. The Evo itself is almost a year old, and the QSD8650 SoC it uses has been available since Q4 2008.

As bkrodgers said, the Shift has better hardware than the Evo. My roomate has one, and that thing really is smooth, even on the stock rom. It nailed like 1400 or something like that on quadrant, not even overclocked on a stock rom. The only changes I ever make to my phone that affects the scrolling is the kernel. My phone doesn't like havs, the voltage scaling makes it unstable, and it lags severely, on any havs kernel. I get the smoothest experience out of my device from a kernel that has no havs and isn't undervolted. Of course, you get bettery battery life out of a kernel with havs, if your phone can tolerate it. Every phone acts differently on different kernels, which is why there are so many to choose from. So you can find the one that's 'just right' on your device. It takes a little playing around and kernel swapping to find the right combo. And as far as I know, basically all the kernels that have been available for a good number of months now, have the fps fix already baked in. When the Evo's first came out, FPS was capped at 30fps. Since then, all the custom kernels allow for it to go much higher than that, sometimes up to 60fps. I don't believe there's much more you can do with that.
Also, for what it's worth, you might want to try out an AOSP rom. They have much less crap in them, and they tend to run very very smooth (in my experiences). Not to talk down on any sense rom, as I also love sense, and 99% of the time and more than happy on whatever sense rom I happen to be running at the time. Fortunately, the Evo has quite a few selections on roms and kernels, so there is quite a bit of playing around and tweaking you can do, in search of the perfect setup.

thanks I'll probably try miks rom to see how that goes.
I understand about the hardware and that the shift has a better cpu, but is there anything else other than what I have already done to make everything nice and speedy UI wise? I think the biggest culprit is the app drawer being clunky. (like this on the shift as well) No settings in linux that can help there?
Oh and kernels. Ive tried 2 of netarchy-toastmods kernels and havent really noticed a difference. Both have had havs. Should I stay away from these type of kernels to get better visual performance?
ANy other tips on which kernels youve tried and noticed better ui results?
ah yes the elections are great. lol I guess I'll have to try a non havs kernel to see how they perform along with the senseless roms.
Thanks all

You're welcome. Just bear in mind, that if you do try out an AOSP rom, that they have different kernels to use. You must use a kernel that was made for AOSP on an AOSP rom. So don't go trying a netarchy kernel on an AOSP rom
Also, I didn't have as good a luck with net's 4.3.4 kernel's as I did on the 4.2.2 or 4.3.2. Also the 4.1.9 kernel's worked great for me. For some reason, the newest one's don't give me the best performance.
As far as tweaking things using ADB, I don't think there's anything you can do FPS related. I believe there are ways to adjust the undervolting in a kernel, using adb, and things like that. But as far as I know, the FPS is what it is at this point, although it will vary from kernel to kernel.

Best rom/kernal combination

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!
Sent from my PC36100 using xda premium

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?

[Q] Best Daily Driver Rom & Kernel

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
Sent from my Incredible 2 using xda premium

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.
