Hey y'all,
I'm going to feel like a bit of an idiot writing this given I've been using the XDA forums for close to 2 years now, but why should I install a custom 3rd party kernal?
I've unlocked my bootloader (finally) to get android 4, and as I understand I can now install custom kernels if I so wish. I'm not too bothered about the process or requirements for doing it, I'll cross that bridge if/when I get to it xD
I understand it can really mess up your system too, so why should I mess around with it for only (minor?) Improvements?
Also, why do custom ROMs have their own kernels? How does a ROM interact with a kernel?
I'm sorry if these is a really stupid questions. Just one of the few things I've wanted to ask for a while now :')
Any good replies will be rewarded with internet cookiez!! Or a click of the like button, you decide and write which you want in the reply xD
Thanks in advance guys

Using custom kernels with custom roms enhance tha rom cos most custom roms work more better on custom kernels...
A custom kernel can be pre-rooted, support OC, vpn support & many more... Some Custom kernels re better dan stock kernel is terms of battery life, smooth & respond!
Messing with tha system can help alot by removing bloatware which slows tha phone & occupy spaces & also customize yur mobile to yur taste!

For the most part, using a custom kernel or the stock kernel is better for a variety of reasons. Mainly, the custom kernels are usually always better than the stock they are based on. They generally run smoother and faster. Yes they are definitely improvements, whether they are small or big, they are still improvements.
Depending on if you are going to use CM roms or even AOKP roms, over stock roms (roms based on stock firmware) will depend on the need of a custom kernel. If you want to run CM or AOKP then yes you will have to use a custom kernel. If you are just running a stock rom, whether it is based on stock or it is the stock firmware, then you dont necessarily need a custom kernel, the stock kernel will work.
But if you want my input, then i would say go for a custom kernel anyway, even if you are on stock. The benefits out weigh the drawback if you can even call them drawbacks.
Hope I've helped,
Cheers,

The way I see it is like this.
Suppose you get a PC with a BIOS and OS locked.If you can flash a newer/modified/improved BIOS along with a tweaked OS,wouldn't you do it sooner or later?!

The X10's flash mode is hard coded in.. so if you set up the flashtool, you can always revert back to a stock original or branded rom. Even if you crash in the middle of rom install, you still have the ability to go back using the flash tool or SEUS repair.
Most roms are a continuing project and in different phases of it.. some are from scratch and some are ports from other phones, all roms have different abilities and perks to running them. CM7 roms give extended system tweaks, and MIUI roms are almost a totally different framework altogether, but they are very smooth.
Kernels are the linux system behind it all, some roms will wipe the original kernel and replace it.. or if you go through the amazing process of unlocking your bootloader, you can have the actual kernel itself replaced.. the perks of this are mostly for overclocking & undervolting to get better performance and/or battery life.
I find no matter which dirrection I go with a rom or kernel, it always seems to have its significant advantages.. If you run into a jam feel free to PM me and I will try and guide you in what ever your venture is, I think I have installed every rom at 1 time or another lol.. best of luck!
even if u brick it can be easily resolved to the normal state...only sometimes it becomes a big pain in a** !! else its cool to go around flashing !!!

basically what are the benifits of custom roms compared to stock kies roms ?
i currently have rr 2.2 rom but appart from the looks and animations etc.. is there a difference in performance/ battery compared to stock?
its been a while sinse i have been on stock so i cant remember what it was like and i just wanted to know are custom roms more better in terms or speed/battery/power etc..

custom rom do come with there own pro's and con's u have to check the changelog of that rom to see whats different in it also some apps which do require root previlage wrks fine with custom roms rather than stock one's
stock roms do have better batt life compared 2 custom ones at the cost of customization with there dull and boring looks
thanks for your reply i guess its just finding the correct balance between customization and battery life then. cheers
go with custom
I had the exact same thoughts when i first decided to flash a custom rom.
Personally i would now flash a custom rom at the drop of a hat, however as the previous comment said there are pros and cons.
do some research on roms with functionality that you require and you'll find one you want to flash no doubt.
hope i helped
i am now running CM9 and its so smooth and looks amazing, a millions times better than stock in almost every way!
Check out the ROM and the comments which people have wrote. Some of them may be good and others may be bad.. you'll be able to work out the missing features of the custom rom bother you or not ^__^ That's how I work out whether to install the ROM XD Most ICS ROM's have their benefits and cons, Gingerbread would be considered the most stable Hope this helps you

What about if I install a custom kernel, but keep my stock rom? Is there any benefit at all?

It's the ROM, not the kernel, that determines if MHL fully works.
Apparently video works with AOSP, but not full mirror of the display.
However, if you want full mirroring, you'll need to be on a stock Samsung based ROM.
That said, you can still run a custom kernel, such as Siyah or SpeedMod, and MHL will still work as long as you remain on the Samsung based ROM.
I'm currently running stock XWLPX with Siyah 4.1.4, and MHL works fully for me.
I am not really too good with this kind of stuff... so bare with me if what i say doessn't make much sense to you guys
I don't want to try different roms yet... wanna stick to stock rom for couple weeks to try it out since i had been waiting for it for months.. but I want to overclock it + add some mods like beats audio etc... I have flashed beats audio but wondering if there are any mods for minor improvements on the stock rom?
I've tried looking through the develoment section but other then beats audio everything requires flashing roms...
and if i flash a kernel does that mean i would get all the mods on that kernel but keep the stock rom?
Thanks guys!
You can try out Carbon booster for those kinds of mods,you onky need to be rooted and have cmw flashed

If you stay stock your ROM is not deodexed. And for many mods to work you need to be. Still there are many things you can do. There are apps on google play which does many things similiar to some of our mods.
One app is called "Power Controls". It is a widget that does everything the 15 toggle mod can do.
You could try a number of launchers. Launchers will give you many features, tools, animations, and themes.
You could install the app "PowerTool" from flapjaxxx. Allows you to reboot into recovery, bootloader, download mode, and the normal.
It all depends on what you are looking to do. That is the thing with android. There is so much that can be done and so many ways to do it.
Hi,
I have been away for a long time here. Been using checkromhd v6 since then. This is a GB rom.
I thought maybe its time to get me a new rom.
I come here and see al these new features : mali, vsync, aroma, dualboot .....
Isn't there a romguide or something? Because this all is getting very difficult.
On gingerbread I think it was easier.
There where lesser option which made it easier to choose. There where also fewer cooks for the SGS2 back then.
If anybody can help me a bit coming up to speed with al this new stuff, I would be very thankfull.

The stickies in the general section have guides to everything right from upgrading from GB to ICS and rooting,dual booting, flashing, etc.
Only thing missing there is details on the latest updates on cm10 and build 4. In brief, the roms based on these two will not run on earlier kernel versions..coz of the new Mali drivers you mentioned.
Aroma basically makes installing a ROM simpler with the help of a GUI. kinda like the installation wizard you have on windows PCs.

Everything is pretty scattered even for people who are sort of on the lookout and have tried various newer ROMs.
Dualboot is a feature in custom kernels, at least Siyah that I know of, where you can have more than one ROM installed and choose at boot time which one to use. I gather that its mostly useful for people wanting to try the experimental builds of Jelly Bean and have a stable Ice Cream Sandwhich.
Aroma is an installer which is sort of a second step after a CWM flash, and before an install, and allows you to choose via checkboxes which extra options you might want. This is up to the ROM maker as for what selections you might have. Examples are sometimes which kernel, which Samsung apps that aren't included in the ROM, etc.
I don't know what mali and vsync are but I would guess that vsync has something to do with graphics and maybe with the experimental Jelly Bean builds.
The only really important thing I can thing of is, as always, to do a nandroid backup before starting anything and possibly since you have Gingerbread you might need an older Kernel on hand with older CWM for a recovery back to Gingerbread... This needs to be addressed by someone who can clarify and it might also be necisarry to flash a newer kernel and CWM that will allow you to enter a recovery mode that will be compatible with newer ROMs but I don't know if this is the case or not. Again, this needs to be addressed by someone more helpful.
More important than the above is that, since you've apparently been out of the loop for a while, there's been a bug that can render a hard brick on some devices depending on various hardware components and the version of CWM used for flashing. There's a sticky thread about this but the safest thing way to go about it, as I understand, is to just not flash a 4.04 ROM but use a 4.03 one. I've used both and prefered the options available in 4.03, for my needs, as far as mods go.
Also, as for Jkay's work, some ROMs incorporate that and some incorporate similar features but aren't near as feature rich. As with Gingerbread there's only so many ROMs that he's done the work for and it now requires not just flashing of a framework, as was in Gingerbread, but purchase of the app from Google Play that will allow you to customize the settings. The thread is here http://forum.xda-developers.com/showthread.php?t=1667846
As for theming, its easier to choose a ROM that has it done already and is compatable with Jkay's framwork (assuming you want those things). You can, use a stock ROM, theme it, install Jkay's framework and it will work quite well but its more work. Vertimus themes are very popular but the site navigation is confusing and will definately be daunting. It would be necissary to read first before making any changes (themes or tweaks) deviating from initial setup. The easiest thing is just to choose something, assuming you want it, already themed and tweaked for Jkay's app to work in advance. Wanam builds seem pretty popular for this and as for the hard brick bug possibility with CWM on 4.04 ROMs, you can probably follow the current Wanam build download into his site and find his forum, search for a 4.0.3 ROM (LPG has played best with my particular handset) and make sure its for the SGSII as people often build for more than one phone and it would be a shame to flash an SGSIII ROM (or something else) on accident, for example.
My recommendation, in summary, is not to worry about dual booting or those other things for the moment, do nandroid backup if you intend to upgrade, find out if you need to have older CWM to downgrade (a flashable one at that in case you get stuck at a boot loop) or a newer one to upgrade, then keep it simple and choose an already themed and Jkay tweaked (you'lle have to buy the app) ROM that isn't a 4.0.4 build of Android, but 4.0.3, and to stay with Samsung based ROMs as a starting point. From there you can get a feel for for things and decide if you like the theming or if you want flash something else with stock Touchwiz, if dual booting is worth the trouble, and then bother to read about the other things you mentioned that I wasn't able to answer... so basically, keep the upgrade simple and then go from there and quite frankly if that means a stock upgrade to unmodified Samsung firmware then so be it.

If they've been updated to run on ICS by the game devs..they will. You'd have yo check that out on the game's page. But since a factory reset is recommended when going from one android version to another you might not be able to save the app data..ie, current state of the game on GB and then resume on ICS.

Custom roms generally have little or no bloat and tend to be fast, almost lagless, however you can get broken features, especially with the S3 because the devs lack Exynos sources. Some examples are if you go from anything other than stock ICS to an AOSP rom you will break NFC, in at least 4.2 roms some video streaming is broken, and there can be various others.
All you can do is read the features lists and known issues to see what the rom can do and what is broken.
The flash counter is a counter in the bootloader, everytime you flash a none stock rom through Odin, or root the counter will increase by one. The counter can be reset with the TriangleAway app by chainfire.
You can use a custom rom that has just been deodexed without any add on and remove what you dont want .

Deodexed = stuff from the odex file is compiled into the app. Eases up themeing but slightly worsens performance.
Though after flashing a rom of your liking you can always do what old man slaphead did: reodex the system
