Difference between ROM and Kernel?

Hello,
Sorry for this very basic question, I am just wondering what is the difference between a Kernel and a ROM? I see in the development forum there are lots of new Kernels, what are these actually optimizing except underclocking or undervolting (understand that terminology). I am also wondering if the Kernels are specific for the original Nexus One 2.1 Android or can you install for example Modaco or Cyan ROM and then a different random Kernel?
Thanks!

To my understanding, a kernel is what directly interacts with the hardware. Every OS has this, but it's more customizable on our phones since it's based on Linux. The Rom contains the OS itself, and the software and file structure therein. The kernel even can tell the OS how fast the processor goes and how much juice to use from the battery.
Hope that makes sense, as I'm no expert. You can mix and match the two as far as I know. I've mixed them, anyway.

Halorin,
Based on what you said, with my stock vibrant ROM 2.1 JI6 update, it is possible to change the kernel or install another kernel (like the CM kernel)?

That is really a question better suited to the rom 's development thread, but in general yes you can flash a different kernel. Some kernel/rom combinations work better than others, but you really wont know until you try. Get comfortable with nandroid backups and start trying out different kernel combinations until you find one you like.

Usually most custom roms will include a kernel but they usually have tweaks like coding for 720p, oc, and audio tweaks and what not. Alsways do a nandroid back up and start exploring. When flashing kernels always wipe, I think their are exceptions but its best to wipe just in case. Browse XDA, download a kernel from your phone browser, rom manager install from SD, should be in your downloads folder, backup and wipe, repeat until your phone does what you want.

which is the better to install???
Thank you your post..
but i can't understand clearly.
so.,
which one is better to install NewRom / Kernal. for android phones.

Neither one is better it just depends on what you want to do.
If you want to totally change over your phone to look and function differently then you need to flash a ROM if you just want to keep the same look but want to enable lets say overclocking then flash an overclocked kernel. If it has to do with the hardware mostly then it's probably something that the kernel can change. Although like mentioned above if you flash a ROM most of the time it will come with a custom kernel.

What he said.
ROMs and kernels are two separate things that have two separate functions. Neither is better than the other, but they do complement each other.

I know both Dude Random21 and codesplice have gone into this, but to try and give a bit more info...
The kernel is kinda like the nervous system of the body. It directly interacts with the hardware (which is how it is able to adjust CPU speed) and it is what allows the ROM to function.
The ROM is the rest of the body. Every other aspect of the phone. In fact, most ROMs include custom kernels. Various ROMs give you various features/enhancements/bugfixes. You will probably notice the biggest change in your phone if you load a custom ROM. Most people load the custom kernels to help with battery life as a lot of them allow you to lower the phones minimum processing speed from 245Mhz to 128MHz.
The ROM can change so many different aspects of how the phone works. There is CyanogenMod which is based off of stock Android with a lot of tweaks, bugfixes, and new features added. There is also MIUI, which is similar to the iOS style (not the same, but much closer than stock Android), and then there are a ton others out there.

Then which Rom is best for my samsung galaxy s???
so i am using froyo.jpjpg on my galaxys.
i want to flash new Rom with upgaraded to gingerbread.
can i flash only rom../ kernal also.
which is best Rom for samsung galaxys.
cynogenmod, miui, .?????
battery drain is very fast now ian running rom/kernal.

Start by going to the forum for your phone.

Nandbackup + Rom & Kernel
One question: when I do a backup with CWM, it is the Nandroid backup you talk about, correct...? Same thing? So, if I do a backup with CWM, it's a backup only of the ROM, or also the stock Kernel...? Imagine that I do a Rom (GingerDX for example), and flash with a custom Kernel.... If things go bad and I do a restore from my backup (stock) CWM, what do I restore? Rom, or Rom + (stock) Kernel...?

Yes, a backup that is done in ClockworkMod (or Amon_RA) is considered a nandroid backup. And this takes a complete snapshot of your system. Your ROM, your kernel, your apps and your data are all inlcuded. The only thing that isn't included is the fat partition on your sdcard. So if things go bad and you restore your nandroid backup, it will go back to however it was when you made the backup.

thanks a lot. reading this thread clear up a lot of things

Hi!
I am currently running Lite'ning ROM 6.1. XXKH3 Kernel version 2.6.35.11-ninphetamine-2.0.5+ [email protected] #20 on SGSII. Phew.
I've tried a lot of ROMS including MIUI, villain, galmetMIUI ICS version . I like Lite'ning ROM because it gave me the least (virtually Nil) problems (FCs/ reboots) and has almost all the features I need (TV-out that's missing from MIUI, good camera with panorama mode, Recording mode in phone). However I miss the CIFS feature. Is it because the kernel does not support it? Can I get CIFS support if I flash another kernel? Any suggesstions on which Kernel should I flash? I realise that this ROM is pretty old now so Can I get additional features with a newer Kernel.

That made everything clear. Thanks man. I'm new to the xda but already flashed a new rom that overclocked my CPU to 1.5 and my HTC Sensation 4G Is running so much better right now. However I wish i knew how to thank people... because i see the thanks meter but cannot find where to thank from.

The rom didn't overclock your phone. The kernel did. READ. You came to the MT4GS forum starting up a storm for people not giving you a direct link to the regular MT4G. How is it you cant find the freakin' "thanks" button? THERE'S A FREAKIN' THANKS BUTTON IN EVERY FREAKIN' POST. OPEN YOUR FREAKIN' EYES.

[Q] Kernel Vs rom - which have the most impact ?

Hello people.
I've been here for 3 months, reading, downloading and learning allot about our great machine and the android system. The one thing i cannot understand is that : people writing allot about the smoothness and fastness of their system. some says this is the kernel, some says this is the rom they installed. What part of smoothness is the quality of the rom and what part is depended on the quality of the kernel ? how many times have your read here "smooth and fast" on the responses of people, not matters if that rom or kernel ?
hope someone can clear this up for me.

A rom includes the kernel .
A rom is the whole OS just like win 7 is an OS .
Kernel is the bit that communicates with the OS at base level between CPU and other components and the OS .
Both have a part to play .
jje

I understand that, but i saw some responses of people, after changing their kernel, says : "ohh.. this is smooth.. and etc..".. how u can tell that this is the kernel ? maybe just by rebooting your phone it gets smoother like when you do it to your computer :}
The only thing i can spot is maybe the sound quality (like on voodoo sound).
how much the stability of your phone depends on the rom itself or the kernel ?

Well it's a good start to get your hands dirty and cook something.

in my opinion, kernels are basically very identical in the sense that they all convert the file system from rfs to ext4 which they just call "lagfix"
all other extras are dependent on developers on what they want to add.

Again, I am not a developer but a user. On the basis of my experience and reading, I would say there are two misconceptions here: (1) roms and kernels are not the same. Many roms embed a kernel as part of the package but both the kernel and the modem are distinct elements that may or may not be packaged within a rom -- the rom may be pre-packaged with a kernel and a modem, or these may be discrete components in and of themselves. (2) kernels are definitely not all identical, especially in terms of source code and modifications, which is the genesis of the dispute on xda which has seen the departure of at least one kernel developer. Compare this list:http://forum.xda-developers.com/showthread.php?t=966646 for kernels with this list for custom roms http://forum.xda-developers.com/showthread.php?t=886000
Most kernels require development, i.e. coding, whilst most roms are a packaging of existing applications and their organization within the framework of the firmware. The phone functions most effectively and efficiently when the kernel and the rom are complimentary. Problems arise when the kernel and rom are not 100% on the same page.
Last element is then the theme which is the visual display of the rom: again there is a separate thread for themes as one can use any number of themes with most roms.

Linus developed the kernel that was passed on then an operating system was laid on top of the kernel .Giving Linux/GNU

Do roms devs do any coding to their roms? i.e. actually changing the coding of the framework etc or do they mearly just "rearrange" things? If not why not seeing as kernel devs actually do some coding to their component.

They do. Start up script is the most common example. Resizing the SD card read partition is also a common feature in many roms (the default read partition is quite small, hence slow media scanning speed.) It also takes quite a bit of effort to make sure that all the features introduced in the rom does not conflict with each other. (Over scroll glow, CRT shut down, extended power menu, etc.)

thank you for the clarification: my choice of words was not as clear in my original post and is no way was intended to diminish the task of compiling and developing a rom -- I also recognize that many tweaks can be approached from changes in either or both the rom and the kernel, but there are elements that are distinct to each.

[Q] Odexed or Deodexed?

Flashed loads of stock and custom roms and currently running stock JVH chainfire rooted.
I'm toying with the idea of flashing a deodexed rom and if I do will probably start off on a stock rom from Ramad - certainly before moving onto a deodexed custom rom.
Question is: is it worth it? I've read the technical differences between odexed and deodexed, but what are the ACTUAL benefits.
Please no replies from people who haven't done it just quoting the same technical information we can all read.
Very interested from those who have - why? why not? what are the performance differences? pros and cons?
I found a thread from April but interested now to hear from all the gingerbread users
thanks

The biggest advantage is you can install themes and various other mods (i.e: different lock screens, extended menus, enable hidden options, and many more..).

It's still possible to install themes on odexed, but not all themes are compatible (Read carefully ).
As for performance.. odexed is supposably slightly better from what I've heard, but I can't tell any difference myself (running odexed JPH atm).

You sure? If odexed is "better" why go to the trouble of flashing deodexed ?

Hi Mossy,
I've been toying with a few deodexed roms of late and honestly, there's not really any noticable difference in feel or performance.
The main benefit has already been mentioned, and that's more compatibilty with custom themes and such.
Some say deodexed has better memory management after the caches are built. Would you or I as a user notice this? Probably not.

OK....thanks guys, appreciate your comments

Rooted Ace: To keep or not to keep (Stock ROM)

Alright. I've searched the forums for 4 hours trying to find different answers to my questions and I haven't had success in all. So, in case I'm that much of an idiot for asking a question that's been answered 1000 times, I'll be happy if you point me in the right direction instead of "politely" asking me to use the search button .
My GF bought an Ace which we were unable to root until we stumbled across the fact the 5830M differs from other models in some ways. We finally got it done yesterday with the help of this thread (I should add the her sole intention of rooting the phone was to expand her Ace's internal memory to be able to install more apps). and we are supposed to partion her SD card (32GB) today. However, after going through so many threads, and deciding CWM will do the partition, we are now unsure about wether we should switch ROM's or keep stock.
So, my question is: Is there any disadvantage of having a rooted phone with its stock ROM? Or better yet: Is there a reason as to why I SHOULD change ROM's?
Thanks in advance.

Hey there,
At this time, there are 3 custom ROMs that are truly different: Razodroid, Retribution ROM and the rest of the deodexed ROMs (2 or 3, I believe).
Let's take each on its own:
Razodroid offers the following:
EXT4 File System
Link2sd
New lock screen
Hard root
Bravia engin
14toogle
Galaxy SII CloCk
New icon pack
Custom bootanimation
Defult *ICS* theme
Ext4 script
Msg limit increased n skins added
Tweaks added
Miui music player added
New google play
All apps updated
New tw Modded
Busybox(latest)
New Launcher
ICS keyboard
Deodex
Zip Aligned System Apps
Sign all apk n zip
Swipe To Clear Notification
Battery saver Tweak
Better Performance
Battery Life increased
Faster SDCARD Read/Write Speed
Click to expand...
Click to collapse
In other words, it will bring you a slight performance boost, more juice, a different look and some (currently buggy/not so smooth) new features such as swipe to clear or 14 toggles.
Retribution ROM has less features. It's mostly about performance, but it's still in a beta stage, so there's more to come:
Smooth Scroll Mod
Build.prop tweaks
Flash Player pre-included
Beats Audio Mod pre-included
Updated libs and modules for better perfomance
Completely ad-free

Click to collapse
Both of these ROMs come along with Rafael's kernel, which adds support to init.d, iptables and cpu governors, among other features. They're useful for running scripts at boot, using firewalls (e.g. DroidWall) and changing the phone's governor (as the name suggests).
Last comes the deodexed ROMs that have no additional features. As any deodexed ROM, they remove odex files, giving you some extra internal space (at the cost of a slight performance hit) and allow easier theming, allowing you to get, for example, an ICS (deodexed) theme for the S5830I (it's made by rajrocks, search for it if you're interested).
To sum it up, there are no disadvantages of having a rooted phone with the stock ROM. Actually, you have almost no reason to get a custom ROM unless you're interested in the new features they bring, especially that performance/battery tweaks can be applied using scripts or manually without needing a custom ROM, if you know what you're doing.
EDIT: You should however consider getting Rafael's latest kernel for the reasons mentioned above: http://forum.xda-developers.com/showthread.php?t=1818830

Very detailed answer. Thanks!
TBH, I think we'll just keep the current ROM (if it was up to me, I'd be tweaking the hell out of the phone) seeing that it isn't really necessary. If we do, we'll be picking option # 1.
Thanks again.

The only disadvantage of installing a custom rom (i think) is the bigger chance of losing your phone's warranty

[q] not a single good rom ?

IS there any good roms for this phone seriously ?
every rom i try has alot of bugs and problems and devs release updates every 6 months and most of them drop the development for the phone anyway
i cant find a single rom that combines performance with battery without sacrificing the LED notification abilities !!!

I've seen comments saying "the best rom" in every rom OP
If 'you' don't like it, it's your view. But don't ask for the best rom as its a violation of xda rules. I hope you get my point and I'm not being rude.
There are many great roms out there, try them for a week or so and then see what's good and what's not, help the dev by reviewing it honestly(not being biased like 'this rom is nothing like xyz rom') this way the dev will help you get a better rom.

First off - respect others work. Everyone puts a lot of effort in the ROMs.
1. The ROMs for SP are nearly bugless, only stock based ROMs have stock Sony bugs.
2. Of course - updates are released every 6 months - how is that possible if PA, AOKP, PAC, FXP CM are weekly-built, and we also have daily-built CM nightlies. Also who dropped support for a ROM? Last time it happened for OmniROM. After that no one dropped ROM support.
3. All ROMs for SP are nearly on par when it comes to battery and performance.
4. You can get the illumination bar features with Illumination Reciever + Illumination Bar Notification apps
5. Why do you put these exclamation marks in your sentences?

try PA or PAC, smooth,fast , great battery life and stable

2 words: thread reported
please respect the work of others and be patient

Also according to the XDA Rules asking for "What is the best ROM" is not allowed here
~~ Regards

hahahahaha you people are being aggressive and rude and i didnt say the "Best" anywhere i said a good rom
and no there are no good roms and i have used every single rom in the development thread and i know every developer and because i respect them i didnt mention their names but i know everyone who doesnt release a single update and leaves the rom to rot or just drops the whole development
everyone is just sensetive when it comes to respecting developers

4. Okay, I can agree, but it's proprietary Sony technology so it can't really be used in CM without weird tricks.
3.Stock is pretty fast starting from .205 update. Eat battery? It depends on that how you flash the ROM, I can easily get 3-4+ hours screen on time.
2. I won't even comment about that, your ignorance totally killed me.
1.FC Festive? Custom ROMs based on AOSP are way stabler than stock ROMs.

i bet that ill find a developer who will comment right now saying that he does this for free and he has a life and he is busy and we should be gratefull
if you are busy and you are doing this for free then why you started it from the beginning ?
just drop the project and delete your thread instead of making us FC everyday and sink in bugs

@aliiahmed.20
I tried AOKP, PAC, PA, CM10.2, CM11, Stock odexed and deodexed, and also ExistenZ from the first version(based on 4.1.2). So yeah, I didn't try them.
Well, looking at your posts I thought you were dirty flashing from stock to CM11 and other ROMs, because with your issues it's impossible that you clean flashed everything.
And about the developers and their work - they can't do that, why? Because people like you will complain about no updates, bugs and no support...

Well, you wrote the correct steps earlier, but you didn't include formatting /system, so in the flashing process some files were left intact thanks by updater-script backuptool.
Anyway, it's not just about the correct or incorrect way. It just seems like a user mistake for me...
Let's end this discussion now, I don't want to fight with anyone about why custom ROMs on their phones perform worse than for happy majority.

Yes, happy majority on(for example) CM/PA/PAC that enjoys the smoothness, stability and battery life of these ROMs(ofc you will argue about that these ROMs have no updates, no support, ppor battery life and performance, but as I said, the discussion about that is ended).

I dont even know why we are wasting our time on you...Pls buy another phone,leave us alone.However, I doubt that even the note 3 will be good for you,as you are lost in space and time.eXistenz was updated 1/7/2014,that was 1 month and almost 2 weeks ago,not 3 months.The reason it wasnt updated is that there is no reason for it to be updated at the moment.The illusion that you put yourself in is false and broken,as only ROMs which arent complete need updates every day,or if they added new features.All stock based roms give you the latest SONY UI,and if you dont like them,SONY isnt the right company for you.None of us notice lag on it,or on any custom rom.I dont know what your complex brain expects from a phone this good.If you arent satisfied,try unlocking the bootloader,and installing FXPCM11,that rom is blazing fast,but the bootloader unlock is the price for it.I am honestly using NexusCM11,and it is fast and smooth as butter.try following install instructions completely,and the ROMs wont lag.You cant just pop a thread,with a goal of insulting people who do much more for their property than you.If you think they all suck,you can make one yourself,so we can admire your ambitions.But the bigger chance is simply that you can not be satisfied,even if someone gave you a xperia z2/galaxy s5/note 3 or the lg g3.You would always complain.But I have an idea!
Care only for performance?
Buy a Nokia phone from the previous century,those things dont lag,and can be used as weapons to smack someones head off.
