[Q] (Q) ROMs and Kernels

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!

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!

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?

ROM comparisons

Hi guys I'm pretty new to the world of Android after going through several generations of iPhones I got bored and love my GS2. Now I see that there's a bunch of roms to choose from and I was curious if there were any websites that specifically review them. In a non biased way. In reality I'm looking for the ROM that has the best battery life but is hard to know based on the individual room descriptions. Thank you in advance and thank you developers for giving us so many options.

Your best bet would be to skim the ROM threads and make a decision on which rom will suit you best based on pros and cons that users report. The number of hits each thread has gives you a vague idea of the popularity of a specific rom. Really the only person that can make unbiased reviews on these roms is you because in the end the "best rom" is entirely up to you and your specific needs

FLASH THEM ALLLLLL
Honestly, all the roms here are quick and smooth.. my DD (daily driver) right now is dewizzed + faux kernel + gideon's script (incredible battery life)
I chose dewizzed because of the simplicity of it.
people say that synergy has good battery life with dewizzed, but you might encounter a few lag stutters here and there? not sure.. im actually testing it right now.
Okay now if you want it to be more stock, i recommend Juggernaut rom, that's probably the best touchwiz rom out right now.. battery life good but not as good as dewizzed.
If you want to see what an android is capable of in a theme category, check out thursday's rom, Tuesday. I played with it for a couple hours but the purple was too much for me. great rom though.
Haven't really tried any of the rest. good luck and welcome!

Since i got my gs2 about a month ago, i flashed the bombaridier 3.5 rom and i never look back.
If battery life is ur top priority this rom iss for u. I easily get 18-20 hours with moderate use everyday. Plus its stable and fast. All i have done is put the ics theme and thats it
Give it a try, u wont regret it
Sent from my SGH-T989 using XDA App

If you want a site that reviews roms and gives some good advice and tricks for the gs2 then go to galaxys2root.com they have stuff for all versions. Btw i am not afilliated with the site at all, i just use it to see the roms before i flash them

ROM comparison topics are not allowed in XDA
it discourages DEVelopments
and also fuels a lot of trolling

[Q] What ROM/Kernel should I use?

So I am not a huge veteran with ROMs and such, and I would like to know of a good ROM and kernel to flash on my GS3.
I use my phone mostly for web browsing, e-mail, light gaming, reading, and listening to music. I like the look of Touch Wiz, but I'll try anything. I would prefer a clean ROM, as in one with no bloat what-so-ever. And I have no idea about the kernel, whatever would work good with the ROM would be nice.
I would appreciate links, and thanks for reading.

This thread will most likely be closed, as the productiveness of a ROM and Kernel depend on usage. (How good a ROM is cannot really be judged, as it varies for everyone.) However, I am ready to provide some guidance. I like TouchWiz and its features, but I have found AOSP to be more responsive. For example, in my case, swiping through homescreens or the app drawer seems to be quicker for me on AOSP. I have also found better battery life on AOSP. You lose many features like the eye tracker when switching to AOSP. For me, that wasn't too big of a deal. So here's my current setup:
ROM: SlimBean Build 3 4.2.2
Kernel: dkp 4.2.x
Kernel Settings Adjuster: Trickster MOD
My goal when installing a ROM/Kernel is maximum battery life with good performance. I am not a heavy user, so I am undervolted -75MPU (I believe MPU is the correct unit) each step and I underclock at 1080MHz. At these settings, I still experience a smooth, quick performance along with a great battery life. With the dkp kernel, I use Trickster MOD (Refer to links above for link).
Good luck on finding what you're looking for! There are many great devs here on XDA. All of their ROMs and Kernels provide the best experience with your device! It all just depends how you use your SIII! Have fun!

Thank you very much, as well as the other poster. I had narrowed it down to 3 ROMs, and I chose to flash AOKP, if not I will try Slim Bean, which was my second pick. Very useful thread there, and once again thanks.

I just this phone lil over a week ago first samsung device and I couldnt be happier!! There's so many kick a$$ roms for this phone im not an aosp guy at all.. Im rocking The peoples rom now and I love it its super smooth and battery life is great:good:

Try out M.O.A.R or Wicked Sensations or The People's ROM

What's the best OOS4 kernel?

Thoughts?

My thought would be that you should move this thread to Q/A thread.
This thread is for development
No idea about the kernel as I don't use oos4

Blu_spark or ElementalX

Kernels are development - this is where users come to get them, and seeing 5-6 different ones doesn't offer a comprehensive comparison, so this thread would serve as that. You read this, and then pick the kernel - all in one place.. But if mods think it should be moved please move it i don't know how

No such thing as a best kernel since everyone uses their devices differently and has different apps installed. Definitely not the place for this forum.

Try all of them, there is no such best. I can say there is a minor difference between Franco, Bluspark, Ex kernel etc. They all cherrypick(not sure it this is the right word) each other and make slight modifications and that makes kernels unique, I had a good experience with Xceed, Render and Franco.

EX Kernel For sure

There is no answer to your question. Best kernel for me may be the worst one for you

Personally, I think this isn't even a legit question as there many variables, such as personal likes and dislikes and desired goals. Some people would rather have a kernel for speed, while others may want increased battery life and yet others may want a little of both. I guess the answer is whichever one you like best.

Useless thread...
There is no best kernel.
You chose a kernel which fits best to your needs.
This is just like asking "whats the best color?"

This thread likely needs to be moved to Q&A.
That being said, I myself would really appreciate some input on pros and cons of well known kernels kind elemental X and Franco vs the stock OOS kernel, since performance isn't something that needs improving IMO on this device. What and how other benefit is there?

Like I said it is all subjective, but if you take the time to read, the information is listed by the OP

You could give the moxie kernel by bedalus a try. He implemented a nice feature where you can set a threshold to make your battery charge to a certain percentage. This is because, if you always charge your phone to 100% the battery degrades quicker.

Lol I liked this "what's the best color?"
I think you people should try Ex . Been using Ex for a while and it seems quite stable.
People say Blusparks is good but for me it was never , maybe its just me.

My sig normally is always updated with a setup working fine on a semi business phone. franco.Kernel is rock solid and the BEST SOT!
