Kernel question - EVO 4G Q&A, Help & Troubleshooting

I rooted mu wife's evo lastnight using unrevoked3. Went awesome. She wants to keep stock rom for now but I wanted to flash her a custom kernel. I have an epic so I'm a little confused on the evo kernels. First off what is a good kernel fir stock rom? I saw the kernels and there are alit if options to choose from between havs and no havs. I wanted to overclock her phone a little bit but from all the threads I read on here a lot of people are against it. Why is that? I know obviously worse battery but I'm overclocked on my epic to 1.4 and my battery life is pretty good cause I also undervolted it. So what kernel di you guys recommend for stock rom. Should I flash a havs or havs not? Thanks for the help guys. I appreciate it. I'm really trying to learn the evo.

Personally never had to overclock my evo. I run CM7, but as far as sense kernels, net achy have the best reviews, and I would go for havs, since it has like a built in setcput to regulate voltages, and help her battery life.

Yeah that's the kernel I was looking at. I'm just having a hard time deciding what subtype to try. I read an awesome article stickied at the top in the development section about the differences but I wanted some user input. It said some phones can't handle havs?
Sent From My Evo Killer!

Yeah, some phones do well with havs while some don't. Same goes with kernels, my phone may act better on one while yours runs like crap. Its mostly trial and error, but start with one that is more-havs. Then theres sbc, (superior battery charging) aka trickle charging. Its pretty controversial right now since 6-10 people out of thousands ruined their batteries with it. You'll definitely get WAY better battery life but be prepared to buy another battery in a year or so ($5 for stock on amazon).
Personally I would try netarchy's 4.3.1-cfs-havs-nosbc and see how it does.

You did state that it was your wife's phone, right? If she is not a techy, all she will care about is that it works. I would leave the default kernel in place and see how she "feels" about it....LOL...If she happy, leave it as-is.
As for what kernel to recommend, definitely a Netarchy kernel as the others have stated. I would start with the toastmod 4.3.2 noHAVS noSBC noUV and then go from there.

I agree and I'm not interested in overclocking it. With the right combination of rom and kernel, I am able to get my EVO to be as fast as I need it to be without sacrificing stability.

Exactly...CM7+Tiamat kernel for me, additionally 100mv undervolted, smartass governor at 128/653...never had a problem.

No my wife isn't techy at all. She doesn't have a clue. She just doesn't like all the bloatware on the phone and finally she asked my hoe to get rid of it. Lol. So she let me root her oho e and then she told me what she didn't want. I might just leave stock kernel on there for now. Her battery is great and she honestly doesn't care about anymore performance. Thank you all for your help. You have really helped me understand the evo a little bit more. I want to buy one myself to just play around with and flash. You guys have so much mire to play around with. The epic is definately limited. I've flashed everything there is to on the epic at least once. Lol.

personally I underclock my evo to save battery, i don't know your wife but chances are she would be better served by a UV then an OC. As for my pick for best stock kernel its htc #15 kernel with sbc found in the sbc thread. by the way what is your evo killer? certainly youre not referring to the epic?

I understand And you're very welcome. I know it is tempting to take her phone and use it for all its worth, but your wife, if she is like mine, would have a cow. My wife has a G-2 and I would love to root it and flash a custom rom among other things, but she could care less about things like that and it drives me crazy....LOL...Still, pushing the issue is not worth sacrificing a peaceful coexistence. You're married so I know you know what I'm talking about.......Anyway, take care and enjoy your weekend.

[Q] simple, hassle free ROM for a friend - Suggestions please

Just rooted my friends Evo and removed some bloatware and optimized things a bit. However he still wants more speed and battery life (closer to what i have with my undervolted, overclocked Droid X)
So it looks like I'm gonna install a full ROM on the phone. However he isn't tech savvy, so it needs to be straight forward to use, with no significant bugs that he's gonna notice and complain about.
Please throw out some suggestions.
bump for this. He started bugging me about flashing a ROM on his Evo again
Does he want a sense Rom if so then go for fresh, myns, or calks. If he wants aosp then go for ofc cyanogen

I just got my evo as well. Ive always preferred the stock htc sense roms. I used nfinitex's stock roms on my hero only for a slight overclock to 691/710mhz.
with the evo, i dont NEED an overclock so I just rooted the stock rom and flashed clockwork. Once i removed all the bloatware and what not, everything is all good. im happy with the performance and the battery life. i just bought a stock battery for it to keep with me if i have a long day.

[Q] Opinions: best sense rom/kernels for battery?

hey guys im sure you get these a lot.
anyway, Ive been running CM6 for awhile now but found out my hometown has 4G coverage now and where i go to school will get 4G in about a month, so I have to make the switch to sense for obvious reasons. Im not huge on performance because frankly i'm not looking to blow minds with benchmarks on quadrant, the phone is fast as **** no matter what so im looking for the best battery life. a must for me is that they keep the theme relatively stock as well, some people arent graphically inclined no offense...
also looking for a good stable kernel with good battery life.
currently running burnt droid with baked kernel #6. heard fresh was good on battery but i think his site, geekfor.me, is down, can someone confirm this?
thanks a lot for your opinions
I don't have 4G here, so I can't say for sure how much 4G affects the battery on this rom, however I've been using Ava-FroyoV10. I do know that the 4G works. I have used it once while I was traveling through a few towns that did have it.
Besides 4G, I do use my phone pretty averagely. In my opinion anyway. I'm usually constantly texting, checking up on eBay using their app, having it plugged into the radio in my car for music, or reading up on engadget. Using Wifi or 3G were applicable. My phone lasts from, about... 8:30AM to around 9 or 10PM. I get a good day's use out of it with Ava-FroyoV10.
I don't use any kernel. I did used to have Netarchy's, however the Ava's stock kernel feels better with the phone. You do not get to adjust your CPU Voltage with the stock kernel.
Your best bet is to surf the Roms and Kernels. Find which one you like best, and stick with it.
Myns warm works pretty well for me with the stock kernel.
plus its a damn good looking rom

[Q] Best ROM With Simple with Working 4G and And Great battery for GF.

hey guys i just rooted my GF phone and wanted to see what good rom you guys recommend for my GF use all she cares about having working 4G and good battery cause stock battery sucks...and simple no bells and wishtles maybe like wifi tethering and thats about it...PLEASE HELP there are so many ROM to chose from!!
Try ricsim's turbo stock great battery life fast and bugless and looks completely stock
Sent from my EVO at the edge of Hell
I am going to have to take a different opinion on this. I would recommend Myn's TwoPointTwo. Myn has done some extensive work throughout the rom to help with battery life. For the excellent battery life that everyone speaks of, flashing a kernel may be necessary, but that is up to you. The biggest selling point for Myn's rom is the support in the thread for his rom. You can almost always ask something and your guaranteed an answer 5 minutes later.
Now do they both come with 4g enabeld ad wifi tethering app and maybe flashing a kernel is risky I want a rom that's all in one...radios....kernels yo know the whole plate...and thank for he relplies keep it comming
Sent from my SPH-D700 using Tapatalk
Myn has all features working 4g,3g, tethering, you name it. And the stock htc kernel is what he packages in his roms, but the latest haven't been bad at all. But I just prefer to get 26 hours of use on one charge. So it depends on how much she wants out of her battery.

Well, currently I am running:
-Myn's warm TwoPointTwo RLS 4 which is the newest release.
-On top of that I flashed the Ziggy Beta 12/14 CFS Kernel.
Personally, I would just get her onto the rom,and have her try out the rom just as is and see how she comes out with batter life. From experience I can tell you the battery you get will reflect on the way your settings are on the phone itself. Like i said earlier, have her test out this kernel thats already in the rom and see how she comes out. Kernels are like women, you have to try out a few before you can find the one that works the best for you.

Nope, pretty solid rom.
Myn's hands down right now, for the best looking (Damn it's pretty), best FULLY functioning, best battery rom, IMO anyway.
HTC should have hired MYN for the overall appearance and UI experience, instead of the crap they tossed together with Sprint.
Another vote for Myn 2.2!!! Best ROM I have ever used.
I gotta agree, I'm using twopointtwo RLS4 and I get 20hours out of my phone with average usage and 10hours with heavy usage.
Without a doubt, Myns is the way to go. I don't think ill ever use anything other than myns( for my daily driver, still like to check others out). Every release is rock solid. Delay no further. And btw, the kernel it comes with, HTC 17, gives my phone the best battery life. I've tried all if ziggys and most of nets. They all ran great, fast, and smooth for me, but the stock did the best overall.

[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.

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.

Epic New Rooter, Few Questions

First things first, i'm not new to rooting I have an Evo 4G and love it, my wife has
an Epic and is having a lot of issues with battery life.
She's not an advanced user but definitely enjoys a lot of the features her phone does have to offer (Facebook sync and custom ringtones to be specific).
I was wondering if anyone could recommend a good stable ROM for me to install to her phone and verify that it can be done after using this rooting method...
http://forum.xda-developers.com/showthread.php?t=770388
Thanks in advance.
Do you want to stick with 2.1, or do you want to go up to unofficial 2.2?
For 2.1, I would suggest Syndicate ROM. For 2.2, if you don't want to mess with the ext4 conversion, I would suggest Bonsai4All 1.1.4.
Sticking with 2.1 and Syndicate...
Anything extra I should know before rooting?
If you're going syndicate it will be perfect. Smooth and extremely stable. I was loving it but I had to be nosey and try the unoffcial 2.2 and am each day getting closer to 2.1. Having insane texting issues with the dk28 modem.

Make sure you get an overclocker to go with syndicates xtreme kernel....
Overclock widget is nice and free, but as far as syndicate goes, I've had much better luck with the paid app setCPU. Plus its more flexible and you can set up the right over/under clocking conditions so she'll never have to worry about it, while providing her better battery life and performance

I'm all for going the tweak method since my wife has a similar issue. But for 20 bucks you can get a 3500mAh battery on ebay from china and avoid the blame when her Facebook wont sync or someother unrelated issue. I have been down this road. I put my wife on midNIGHT 2.9 and it gives a pretty good jump in battery life...but had to suffer the wrath when the contacts didn't sync the same. So trust me if your wife isn't into this stuff...take the easy route. I did...put her back to stock and now she can't blame you for Android issues...haha.
