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.

Hi there! I'm new to the forum and to android as well.
As you can guess I'm a proud owner of SGS
Since my SGS sucks a bit (random crashes, reboot, RFS) I'm interested in taking the maximum out of it, and I have some questions.
What is the difference between kernel and a rom? As far as I know from Linux and OS theory, kernel is the layer between the user (applications) and the hardware. I also know that most of the ROMs have kernel in them. Then what else the ROM contains?
What is firmware? Is it used a synonym for kernel/rom?
Is it worth installing custom kernel/rom on SGS? I'm a bit paranoid in those things and have some fears about the issue.
Is there a way to install some good kernel (like speedmod) and naked ROM (not someones mod, i.e. a stock android ROM without any additions from third party developers)? Is it hard to make my own ROM based on stock ROM (without touching the kernel, even tough I looked at the code and read books about the linux kernel, I dont yet consider my self a guru to be able to make my own kernel for android), just the modification and custom applications?
Thanks a lot guys!
Everyone has a kernel - even if you don't mod your phone at all. It wouldn't work without one!
Now, if you flash a ROM, you change the whole system including the kernel. If you flash a kernel, you're only changing the core piece of your system.

A rom is a full firmware .
A kernel is the bit at the base level between processors and OS .Or just as you said .
Is it worth installing custom kernel/rom on SGS? I'm a bit paranoid in those things and have some fears about the issue.
YES but its at your risk though SGS is relatively un brick able .
Simplest upgrade would be via Rom Kitchen and build your own rom .
Choose base rom kernel modem and CSC to suit plus themes and apps .

The kernel in android is essentially just a customized Linux kernel. The ROM is basically the application layer and the framework. Usually ROMs include kernels, but you can flash a different compatible kernel.
Firmware usually refers to either all the basic software on your phone (minus the apps) or the ROM, csc and modem.
You can definetly flash a custom kernel onto a stock ROM, which will improve performance a great deal even without a custom ROM. Find instructions aplenty here on XDA.

By un brick able you mean that its hard to brick it, or if I brick it its hard to un brick (fix) it then?
Also I'm having a hard understanding, if kernel is the thing that manages the hardware and also responsible for lagfix then kernel is really what matters for the performance of the phone. How a ROM could improve phones performance?
Also one more questions:
As I understand CSC and modem are connectivity related files (3G internet, APNS etc) right? So its better not to touch them when flashing custom ROM/kernel?
Thanks a lot again!
JJEgan means it's really hard to get to brick your SGS.
The kernel is responsible for the proper functionality and cooperation between hardware parts. As for SGS, it is a common belief that Samsung's RFS is not as robust or "agile" as ext4 FS. Thus, converting RFS to ext4 should increase device's performance (the time needed for the read/write operations to take place is decreased). BUT, in order for the device to function properly, the kernel MUST support ext4 as a file system format otherwise it won't work anymore (This could happen after installing a stock kernel on a device that uses some filesystem apart from rfs). Samsung's stock kernel does not, so you have to replace it, if that's the case.
(E.g. If you format a USB drive under Windows 7 with "exFAT" as its filesystem, you won't be able to access it through Windows XP for example, because XP does not support "exFAT" - Different kernels & Different OS version ).
Yes, CSC and modem.bin are what makes your device a TELEPHONE, too Connectivity issues between your operator and your handset depend on those files. If you can find the latest COMPATIBLE modem file, then go for it.
Thanks for the explanation!
As for CSC and modem, by compatible you mean the same version (XXJPY for example)? How do I know they are compatible with my phone?
Thanks a lot again!
the CSC doesnt have to match the baseband. for exapmle, you can have XXJPY baseband and XXJQ1 modem. (thats what i used to run)
its all about finding the right modem for your region, you want to make sure you get good connections dont ya ? modems affect SMS, Calls, Data, WIFI, so on.....
so you want the right one. If you go to rom kitchen, you can see all the modems and what region they cover
Thanks!
But is there a way not to touch the CSC/modem when flashing custom kernel/ROM? I'm really afraid to mess with those.
Also could someone refer to this question:

Think of the kernel as the drivers and the ROM as the OS. If your drivers are from 1987, windows 7 wont run well, if at all. However, you can have the newest 2011 drivers installed on Windows 95....same thing. Kernel and ROM must be well suited and work together for a good experience.

Actually if you are flashing a three file firmware with odin, PDA is the ROM, which in this case usually includes a kernel.
If you are flashing a kernel alone onto an already installed ROM, then the kernel is put in the PDA field.

Gingerbread needs a different kernel than Froyo, right?
every firmwarerelease (JVQ, JVP, JVR, JVS, etc..) has its own kernel version.
but with talondev im not sure, cuz there is no distinction between the kernel versions.
with all other custom kernel releases you have specific kernel versions.
yep 10 charrrrr

Actually most custom kernels can work with any firmware build for the same version, froyo or gb. Some devs may base a kernel on a specific firmware, but they usually work on all.

I Have Rooted my Note with Odin and are on kernel KK5.. Im thinking of install a new kernel and getting a custom rom for improve the speed, battery and hopefully no lag after reading different topics here, its pretty hard too choose? anyone know for sure whats the best out?
Look at them all, read the responses, then pick one. There is no such thing as "best".
Agreed!
Its what best suits your needs. CF-Root may be considered as the most stable and close to stock as possible with just Root.
That may be what you want to start with.
The best ones are: of your considering and best choice to fit your device
yes there is not a best rom (never ask about which is the best rom)
there are different roms
some uses some devices/cpu drivers/controllers/governors some not, some are lighter some are more heavy
some looks quite similar to stock and some others are completely different
some boost speed others boost battery usage
i think that for make a good choice 1st element is to see who made the rom: there are some devs who have been tweacking/writing roms for years on older devices and have a strong strong reputation
2nd element very important is to check the comments of the people who tried it on the threads: read 1st page of the post and then go to last page and read the 10/20 last replies
usually for noobs like you and me the best is to go for a well tested rom without 2 many problems
i wouldnt dare to install cyanogenmod 9 so far....
anyway if i were you i would try the rocket rom vers 20 and then upgrade to rocket rom 21
this rom has a long development and its quite reliable
being .21 version many bugs have been amended and the dev is very active and nice.
2 go for reliable rom as beginner is the most intelligent choice!
hope to have been helpful

Hi, my name is g4ndr1k and I'm a flash addict.
I've tried almost every ROM and now I am on DarkyROM. Hopefully it would be my last before ICS.
My other favorites are Cassie's, CheckROM, KingDroid and Romow.
For giving a precise answer (of course, only IMHO):
CheckRom v5 with either CF Root oder SpeedMod Kernel.
But, in general: use what suits your needs best. How? take a look at every ROM.
Honestly as of now the custom ROM's dont really stand out that much compared to the stock ones, on a day to day basis with a blind test no one can tell the difference.
I was looking for smoothness, stability and the minimum lag without changing a lot in UI, stock LA4 deodexed with fm 2.0 kernel was my best choice after trying several roms, I'm satisfied with what i have before the ICS comes out.

if you already rooted and installed CWM recovery, then no need to flash using Odin.
just copy Zip (ROM) to SD card and reboot in CWM recovery then flash.

Im actually starting too wonder if id used Odin.. This is the package i used: DooMLoRD_v3_ROOT-zergRush-busybox-su
but anyway, i dont think i have CWM recovery installed, i have downloaded Rom Manager, but when i push the Flash ClockworkMod Recovery. I can only choose between a few samsung choices like SII but no Galaxy Note?
Currently on rocket 21 but id highly recommend checkROM v5. Seems the most stable with superb performance and battery. Flash abyss kernel 3.5 and overclock and undervolt to 1600. Guarantee you'll love it. With checkrom you can install missing Samsung apps from kitchen and a variety of mods to suit your needs. Would recommend ics keyboard if you use fingers to type or swype if you use the pen a lot.

I am new to this forum,so first let me introduce myself.I am a doctor in india.
I bought this phone last year and like most users i was really disappointed with it. Intially it was froyo and then with extreme difficulty I updated to lg stock Gingerbread using its update too.I think the tool itself was buggy like most lg stock ROMs.
Anyway updating to gingerbread was a bad experiance .Too much lag in doing even basic phone use ,forget a smart phone experiance.Anyway not explaining in detail all the problems ,we all know it.
Was waiting for Official ICS release,so never thought of Unofficial ROMS since wud have made it difficult to update to stock ICS by company.
But last weak finally decided to try CM based ROMS and after some research decided to try Temasek CM7 based unofficial ROM build 132,
I must say what an experiance I had.From awesome to wow ,i am short of words to describe it .
So here i must thank everyone involved with XDA and especially cynogenmod and Temasek in perticular.
Thank you Temasek
Thank you XDA
Thank you cynogenmod
You all have made this ****ty phone into a delight to use .
I have installed " n " no of applications and still there is no lag and there is no shortage of RAM(and LAG due to IT) even after i week of using it ,which i used to have with stock gingerbread.
I must say i had been a noob and XDA and all you developers have made me into a mobile phone expert rooter ,flasher, etc.
I had few issues which i wud like to discuss,thanks in advance to anyone who helps me solve these.
I had flashed temasek CM7 build 132.and I had thought it wud also flash latest temasek kernel but it seems it didn't.
It now has kernal version [email protected] # 1
Mod version CM7-20120809
I basically want
1.A kernel with voodoo sound support
2.Ramhack
3.Good battery performance with 3G on.
4.Camera mod if possible.
Temesek could you give a small tutorial on variour kernels made by you,I looked various log changes made by you on p990 kernels but i am very confused.
Also what is difference b/w OC and uv etc
I have spent two days installing various applications on your ROM, so obviously will not like to do factory reset,data reset ,cache reset etc
before flashing any new kernel made by you.Kindly provide some suggestions on what i shud do.
Symbiosis kernel looks promising too but again don't want to wipe anything basically reinstalling all applications all over again.Any suggestions.
And yes I am sure you people in XDA wud soon release a fully functional ICS and even a jellybean based ROMS.So Now with my experiance i can say dont eeven want a LG stock ICS or jellybean even if they release it,untill then I wud stick to this wonderfull ROM by temasek
Thanks everyone and all the best to developers in their efforts on developing a fully functional ICS /jellybean based ROM.Hope to see it soon.
Hi if you already have temasek ROM installed on your phone you can flash latest symbi0sis kernel 1.1.2 without loosing any data! just flash the kernel via cwm and boot the phone - done
also symbi0sis is based on temasek kernel, works perfectly with temaseks ROM
after kernel install u can open the app GuesteOC and enable the ramhack with your preferred size in MB

Thanks for quick reply stefan.
So does that mean i dont need to do data/factory reset or cache reset before flashing symbiosis kernel or any other kernal .I have tons of app's installed ,don't you there can be bugs if i dont do a factory/cache reset before flashing symbiosis kernel.Its written in most threads that kernel flashing is similar to ROM flashing ,so data/ cache rest is advisable.
Where can i find GuesteOC app or can i use terminal emulator method as described in some threads

Np just flash the kernel without any wipes. it will wipe dalvik cache automatically. i guarantee you it won`t break your apps.
GuesteOC is included and will be installed automatically. no need for command line, everything as simple as possible with symbi0sis kernel!
if you try other kernels you might need to wipe dalvik cache first if they dont do automatically!
also u can do a backup in cwm first so if something goes wrong you restore the backup with all your apps.
Thanks stefan i will apply your Kernel today itself.Hope it solves everything ,Voodoo sound support ( i have the app with me) ramhack and good battery life too.Will post back if i face any issue.and offcourse my compliments
Also another question to you .You have said CWM backup/Restore .I did the same 3 days back before installing temasek ROM.But had forgotten to keep backup of some important SMS messages so tried to restore original stock LG ROM through CWM back up/and restore.
I Had a real shock it said that i had restored everything but my LG started rebooting again and again just stops at LG logo everytime.Even recoery was not accessible.So i had a torrid time going through variuos XDA thread .NVflashed stock froyo ROM and then flashed temasek ROM.
The only thing i missed was that i pressed backup/and restore straight from CWM app instead of going through manual recovery doing data/cache wipe and then restoring from Backup image.
Can you through some light on the serious issue that i had

I Had a real shock it said that i had restored everything but my LG started rebooting again and again just stops at LG logo everytime.Even recoery was not accessible.So i had a torrid time going through variuos XDA thread .NVflashed stock froyo ROM and then flashed temasek ROM.
The only thing i missed was that i pressed backup/and restore straight from CWM app instead of going through manual recovery doing data/cache wipe and then restoring from Backup image.
Can you through some light on the serious issue that i had

Maybe it had to do with different file system (ext3 stock / ext4 temasek) -- afaik you need to flash back2ext3 or something when you want to go back to original stock ROM. However I have never done that (going back to orig stock). Next time best use "SMS Backup & Restore" (available in market) for backing up and restoring SMS after ROM change!
Good luck with the new kernel I'm sure everything will be fine.

I am new to this forum,so first let me introduce myself.I am a doctor in india.
I bought this phone last year and like most users i was really disappointed with it. Intially it was froyo and then with extreme difficulty I updated to lg stock Gingerbread using its update too.I think the tool itself was buggy like most lg stock ROMs.
Anyway updating to gingerbread was a bad experiance .Too much lag in doing even basic phone use ,forget a smart phone experiance.Anyway not explaining in detail all the problems ,we all know it.
Was waiting for Official ICS release,so never thought of Unofficial ROMS since wud have made it difficult to update to stock ICS by company.
But last weak finally decided to try CM based ROMS and after some research decided to try Temasek CM7 based unofficial ROM build 132,
I must say what an experiance I had.From awesome to wow ,i am short of words to describe it .
So here i must thank everyone involved with XDA and especially cynogenmod and Temasek in perticular.
Thank you Temasek
Thank you XDA
Thank you cynogenmod
You all have made this ****ty phone into a delight to use .
I have installed " n " no of applications and still there is no lag and there is no shortage of RAM(and LAG due to IT) even after i week of using it ,which i used to have with stock gingerbread.
I must say i had been a noob and XDA and all you developers have made me into a mobile phone expert rooter ,flasher, etc.
I had few issues which i wud like to discuss,thanks in advance to anyone who helps me solve these.
I had flashed temasek CM7 build 132.and I had thought it wud also flash latest temasek kernel but it seems it didn't.
It now has kernal version [email protected] # 1
Mod version CM7-20120809
I basically want
1.A kernel with voodoo sound support
2.Ramhack
3.Good battery performance with 3G on.
4.Camera mod if possible.
Temesek could you give a small tutorial on variour kernels made by you,I looked various log changes made by you on p990 kernels but i am very confused.
Also what is difference b/w OC and uv etc
I have spent two days installing various applications on your ROM, so obviously will not like to do factory reset,data reset ,cache reset etc
before flashing any new kernel made by you.Kindly provide some suggestions on what i shud do.
Symbiosis kernel looks promising too but again don't want to wipe anything basically reinstalling all applications all over again.Any suggestions.
And yes I am sure you people in XDA wud soon release a fully functional ICS and even a jellybean based ROMS.So Now with my experiance i can say dont eeven want a LG stock ICS or jellybean even if they release it,untill then I wud stick to this wonderfull ROM by temasek
Thanks everyone and all the best to developers in their efforts on developing a fully functional ICS /jellybean based ROM.Hope to see it soon.

Do restores this way
1>wipe data/factory reset
2>wipe cache partition
3>flash back2ext3
4>restore
Upgrade your cwm recovery to 5.0.2.0 or 5.0.2.8 (non-touch cwm)

Thanks everyone all issues solved ,and i knw now whuy i bricked my phone while restoring back.
Stefen your kernel is awesome.Perfect combination for temasek's ROM
I think i will stick to this ROM for a while,untill temasek or someone comes out with a fully functional ICS/jellybean based ROM.Will never flash stock LG ICS's based ROM even if LG bring it out(Hope LG release it soon that shud provide d missing drivers that we urgently need).
Temasek your ROM is d "project butter" for me.I dont feel d need to wait for jellybean ROM.And yes i already have cwm 5.0.20 version recovery installed.
Hello, I recently bought myself a new Galaxy S i9000 for mostly multi-media purposes. I was looking for a smartphone that would suit my audiophilia needs and after lots of googling I found out that this is just the phone for that, so I bit the bullet and bought an unlocked one
Came in the mail today and I need your help with this! I've had androids before so I am somewhat familiar with the ecosystem, however since I joined the galaxy S bandwagon quite late, I'm REALLY behind on Roms and such.
Obviously, since I bought such an old device, I had my reasons; which are music. I'm gonna root this soon and I wanna install a rom with these sort of features.
I need a rom thats:
-Smooth as it can be
-Has the Voodoo Sound Kernal (according to everybody, that's how one unleashes the full potential of the sound)
-....won't get rid of my unlock
I don't care for customization, games, social media, etc. I just want a rom that's smooth, responsive, and has voodoo so I can enjoy my music on the go
Thanks!
If you want to go for custom ROMs then CM 10 all the way, its nighty so is still has bugs. But is good enough for daily usage. And damn is smooth I will never go back to GB or anything else...
You can try also CM 9, there is a stable version. Look for it in the development section.
This phone once unlocked, will never lock again!! unless you want to

CM10 Definitely LOOKS smooth, but is it fast and responsive? I've seen youtube videos (the very few there are) of single core phones that can only handle CM10 somewhat OK....they are somewhat smooth, but unresponsive when it comes to opening apps and menus (lots of loading and stuff). So is CM10 for this phone fast as well as smooth?

JB Custom Rom C-RoM Mix or C-RoM BeaN are highly recommended. You won't get disappointed with these Roms.
I've tried several Custom Roms, but i found C-RoMs to be the best, very fast, smooth, responsive, and stable.
This JB Custom C-RoM was benchmarked by Ratborg to be the fastest JB Custom Rom.
The kernel (Semaphore) supports Voodoo Sound.

Wow this is great, thanks alot friend!
Umm, but could you help me out I've flashed ROMS before but I've never flashed a kernel ever. How do I safely and efficiently do that? I just rooted my device and am now running stock 2.2 . How do I go on about flashing the kernal and the Rom? This looks amazing!

The Rom contains the Kernel already, so unless you want to change or upgrade the built-in Kernel that's the time you have to flash it.
Flashing of Rom or Kernel usually can be made through CWM by going into Recovery Mode.
If you're coming from Gingerbread, the safest procedure is to flash an ICS CM9 first before this recommended C-RoM (which is based on CM10 and AOKP), this is to avoid getting your IMEI invalid.
During flashing of a Rom, you will have to re-flash twice or sometimes 3x before getting successful due to Android system and Partition Layout differences.
Don't forget to backup your important database and applications via Titanium Backup or GoBackup so you can restore them back after successfully flashing the new Rom.
Good luck and enjoy flashing.
Try this configuration, i have it my self... it runs really well, is not unresponssive at all, maybe some hiccups but overall is good.

Alright so this ROM contains the "sephamore" kernal with voodoo sound itself? Cool! Um, so I first flash a CM9 ROM, and then from there flash this?

Yes the Rom contains Semaphore kernel and yes you have to flash CM9 first and from there flash C-RoM.
Semaphore kernel supports vodoo sound but i think you have to install an application that produces the voodoo sound itself. I'm not sure but you have to further research on this.
