[Q] Where has kernel development gone?? D: - Epic 4G Q&A, Help & Troubleshooting

Sooo its been a while since i have seen any new MTD kernels besides one for CM9...anyone working on anything??

Because CM9 is where it is at.

And they probably feel they have taken the kernels on TW EL30 MTD as far as they can go. Earthbound may have a newer MTD kernel on his IAP sight.

I don't get this. If custom kernelss have integrated many performance enhancing features then why do we keep needing new ones? Isn't it a good thing if we've gotten everything we need out of them and can just use the phones? I mean if someone finds something else that can be done I'm all for it, but this sounds more like a flasher addict's cry for a fix than anything else.

If you think about the stock kernel is a custom one too just someones kernel pre packaged is all and to think of it when something doesn't work out and needs tweaking what happens the dev's of the rom tweak the pre packaged kernel.
Seems like just because someone else's kernel doesn't mean they aren't going to do the same thing. Adding stuff to a kernel more features, makes it more friendly and helps in the long end dont you think?

Simple Question.... Re: Kernel

I know I need a Kernel that supports overclocking before I use something like CPUBoost... which one can anyone recommend that is stable and would allow this.
Sorry this is my first time posting in this forum... was using the Eris up until yesterday.
Thanks in advance.

It's all preference, depends on if you are using an AOSP rom or Sense rom. Try them out for yourself and then decide, everyone gets different results.
I'm just throwing this out there we can only overclock our phones a wee bit and it for me at least destroys battery life.

honestly you could probably get away with just installing some of the AOSP kernels floating around the Dev threads...I LOVE invisibleks line of kernels, #28 is a champion for me...but I believe the new Tiamat line of kernels is concentrating on aggressive undervolting...I would give them a try
Might try that... it's weird, coming from an Eris, there's definitely a more professional way about this forum. BUT (big but).... the ROM's seems to be overall more incomplete and I am worried about losing somee functionality. So installing a Kernel would be my best bet I guess.... being I would retain all the functionality of the stock ROM.
Hope I make sense.
Oh the other thing is... when a kernel is AOSP compatible, that means stock ROM also right?

Help with kernel

Im sorry, the samsung set up seems so much more confusing than an htc phone and i was wondering what kernels work with the bonsai rom and maybe if there are any SBC kernels or if anyone recommends any?
Go to the dev section and search for kernels to see what works...as far as opinion, see my signature.
Sent from my SPH-D700 using XDA App
From personal experience, most kernels in the dev section break root with bonsai. If you like the bonsai rom, you're best sticking with the bonsai kernel.

POLL: What is your favorite rom thus far

Just wondering what everyone else likes for a rom. Feel free to tell us your likes or dislikes with your current rom. With the choices we have available to us on this device, I'm sure some are wondering which rom is right for them.... this poll should give people some kind of direction.
EDIT: I must apologize. I must of been tired to miss putting viperROM on the poll list. Don't suppose there is a way to edit that poll is there?
I'm loving Starburst and glad I finally budged out of my curmudgeonly ways off of stock as I wait for CM. It's very full featured and allows tweaking without turning into a theme-fest. I was very surprised with it.
Though I am also preparing my phone to try out some other ROMs today....I'm a big fan of Calkulins work so I'm pretty eager to try that out.
Calkulin FTW
Although to be fair I haven't tried starburst yet. Didnt boot when I tried it but it was my first attempt at a custom ROM on this phone so I am sure I did something wrong

Liking Starburst quite a bit. My phone is fast and reliable, waiting for further advancements before trying something else.
Sent from my SPH-D710 using XDA App
I haven't tried anything besides stock and star burst.I was seriously going to open a thread like this because I'm convinced that caulkin's is probably better. But my phones set up o-soo perfect right now idk what to do. After j see screenies and some themes for caulkin anhd hear good things about battery and smoothness I'm going to hold tight
If you want stable I'd go for this AOSP mod

I cringe when I see other people having problems on other roms, ranging from battery life to stability issues. I'll only leave this for ICS.
Sent from my SPH-D710 using xda premium
No doubt caulkulins roms is the best
Much smoother and faster than starburst or viper

To be honest, and maybe this means I'm a ****, but when I read about people having all kinds of problems with a rom or a kernel or a mod or anything my first thought is automatically "they probably fncked something up."
A vast majority of the times this is, in fact, the problem. I'm on my 8th? 9th? Android device. I hack 'em up to pieces. I try to be a good boy and read everything thoroughly...but I don't. I skim for the important bits. If I screw something up it's usually pretty obvious, then I fix it, then it works. I have never actually had a ROM that has destroyed my battery life (I have with experimental kernels, but, to be expected), I have never lost 3G function, I have never gotten unfixable bootloops, I have never killed my wifi or 4G to where a full wipe and reflash didn't bring it back...never. For years now I have been hearing some wild problems from people and never actually experienced any of them for myself in a way that wasn't fixable, by myself.
I have gotten better battery life, faster internet, working youtube, faster wifi (the 'wifi n' mod on Evo4G), etc etc etc.
I don't know, I'm always skeptical of people claiming a rom or kernel are screwing things up when there are other people with no problems at all.
Alpha and Beta roms notwithstanding, lol
viper for some reason not on here..
but anyway, my vote is for viper. Need to try Calkulin more though
yeah.. where's viper? I think the rom is quiet good.. and nobody 's seems to complain much on his thread..

How are ROMs different?

So I'm just wondering what makes all the ROMs different? Specifically all the TW ROMs. I understand that each dev uses different tweaks and stuff but what are they exactly..? What are the different things tweaked that make a ROM different and maybe even better than other ROMs? And if a certain tweak makes the ROM better then why don't all ROMs have the same tweaks and edits?

There are barely any major differences in TW ROMs besides preference of kernel

See, that's what I was thinking because I've tried like every TW ROM at least once and to me battery life is almost always the same and so is performance. The only differences I ever feel is depending on the kernel. And I also feel like some ROMs go better with a certain kernel then others do.
But other than the choice of kernel I don't see any difference. So not to discourage anyone or diss anyone or anything like that but why do people even make TW ROMs and claim that their ROM is better if all are actually the same kinda?

Aww, I miss the viperRoms
There's a lot of times themed APKs, which sometimes requires modified XMLs and modified PNG files.
There are some extra scripts in system/etc/init.d and lines in build.prop that optimize speed by making things mount faster or making it possible for more applications to be open.
Also, there can be modified framework to add features or change look and feel or speed. Ex: on HTC devices, the framework can be modified to get rid of the paginated app drawer on Sense. Can't think of any specific Samsung examples because I've never made tweaked stock ROMs but mostly do ports.

A lil help getting around.

So I'm getting the t-mobile gsii soon. I currently have the epic 4G. I looked in ur dev section and seen a lot of ROMs but noticed that from the titles I didn't see any 4.2.2 ROMs, is there any? I'm expecting yes, since my epic 4g has a handful of them already.
Do you guys have slimbean? If not, any recommendations for the closest ROM to slim?
And your kernels support voodoo sound correct?

EDIT: so I found some 4.2.2 roms and even slimbean.
I'm still a lil confused about the kernels tho.
There's different kernels for stock tw, jb 4.1.2 and 4.2.2? Do they have
And another thing is the radios, are they like modems?

Kernels come with the ROM. Most of the time it can stay where its at and you'll never know the difference. For a 4.2 ROM, i'm partial to AvatarROM. And we have 10.1 nightlys posted on the page as well. If you want stability, 4.1 is the best choice ATM. Jedi Mind Trick JB v4 is a great choice. (look at me... Plugging all these ROM's. lol) Its super stable and you can swap out kernels if you need to. It doesn't have a theme engine in it yet, but the avatar rom does have themeing though. Your chice. IDK about the Voodoo sound. That kinda died with GB. The new ROM's have Beats audio and the DSP manager. Does better than Voodoo. Radios are like modems, yes. They can be swapped out but need to be compatible with your kernel in order to function properly. UVMC6 comes with most ROM's but I like the radio from the Note2, UVLG3. Most ROM's can utilize a Kernel Tuner and an app called Trickster MOD from the playstore. You can set idle frequencies and make it so only one core runs until a load is placed on the phone. Real battery saver. And make sure your flashing the right Gapps packages for the ROM. 4.2 Gapps won't work with 4.1 even though they are both JB. Hope that helped. Any other questions, PM me.

Yup, thanks. That was almost everything I needed to know. I'm not a total nube so I understand how everything works, its just you guys have some things different than what I'm used to from the Epic 4G forum. I've rooted this device before so I shouldn't have a problem with that and I'm familiar with a few of your ROMs such as Avatar, but I'm going to have to try some new ones to see what I really like. Thanks for you reply tho, ill probably have more questions once I actually get the phone by the end of this month.
