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.

[Q] Best rom for optimus 2x

Hello guys
I got an optimus 2x, and was planning to root it, or whatever you call it From day one, I was really dissapointed with the LG stuff, it got better with launcherPro, which made my homescreen much much faster and smoother. I think this phone has enormous potensial, but bad software. Therefore, since I am new to this forum, I am looking for the "best" root or rom thing for it. Maybe there is many different versions, but I like things clean, simple, fast and smooth. thats what she said.
Anyway, I've seen a friends rootet xperia, and he said he got some new UI with folders and stuff. I dont mind this, only it is good, and maybe it will be customisable still?
Problems Ive had with the phone: Random shuttdown, ugly apps like facebook for LG and antivirus etc. Buggy lockscreen. Battery goes to 0% when it randomly shuts down.
Is it wise to get 2.3 on the optimus 2x? I would love some inputs from you guys also, what you like the best and some general experience. Will I be able to update my phone when im rooted, like from the settings options from the phone? dno if this is important or not.
Anyway, links would be appriciated to official threads or direct links to your recomended roots/roms. Thanks

I have no experience with this, so a HOWTO guide or a youtube vid would be nice. Ive only done jailbreaking on 3.1.2 on 3gs

Cm7 is still in a nightly on the o2x but it has alot of bugs, i think. Mdc fr17 is very stable and fast, it's 2.2.2 though

If you want a clean, simple, fast and smooth ROM like you said ide go for the Modaco Fr17 Vanilla version -
http://android.modaco.com/content/l...om-rom-for-the-lg-optimus-2x-vanilla-edition/
This is also extremely stable as its based on the stock ROM but with all bloatware removed, also read some of the pinned topics on the links below, this will show you all you need to do.
http://android.modaco.com/category/506/lg-optimus-2x-2x-modaco-com/

For bleeding edge stuff, hope on the CM7 nightly train, but don't complain if it crashes.
If you want stability, then try the MoDaCo stock based ones.
You don't need much of a tutorial to do it, use SuperOneClick to gain root, grab ROM Manager from the Market and use that to install ClockworkMod Recovery... download the ROM you want, wipe & install (also via CWM if you don't want to fiddle)

Hi
If you don't want to install a custom ROM:
have a look at this thread http://forum.xda-developers.com/showthread.php?t=1037751
-Install latest firmware and baseband for your region (or another region if you prefer)
-root your phone
-Install ROM Manager from Market and install ClockWorkMod Recovery from there
-Install dexopt fix
Now that you have a good base, look in market for an app to uninstall system apps (I have used Root Uninstaller). To completely remove system apps I think you need to remount /system rw, else you can freeze apps for easy restoring if you mess up.
I would also recommend installing launcherpro from market (replace home screen and app drawer) and google stock lockscreen http://forum.xda-developers.com/showthread.php?t=1033776&highlight=aosp+lockscreen

Thanks for the help guys. Im gonna try the Modaco Fr17 Vanilla version. I have an exam tmrow and will therefore not try it out until the afternoon. I also have to read some, and learn the difference between root and boot, and some of ur advance words havent found a real guide yet, but have the iso and all those other folders that was in the Modaco Fr17 Vanilla version.
great fun

I think the phone drain battery too fast in 2.2 (official rom)
I loose 40% of battery within 6 hours without using anything (when I'm sleeping during a night)
That's why I change to use 2.3 and I found that the battery problem is gone
I loose 1% in 12 hours.

I'm also new to the fun world of android. I've learned alot by simply reading threads and using google to explain som of the terms Read the roll up thread very thorougly, explains alot.
I'm now using CM nightly #31 and it's been very stable for me.
Just do some backups and start toying around with your phone, it's fun!

..but I like things clean, simple, fast and smooth = cyanogenmod!

So far, from temasek is the best.. he got a custom kernel too.

My Opinion,
Android 2.3 from teamsek. It is just brilliant.
Android 4.0 from xxMrHyde + Nova Kernel is quite good keeping in mind the state of ICS on the 2X.

then when they want to go further flash a Custom Kernel (for CM7 i think the best one is Etana)
after that take what ever you want! Try, try and try.

Me too, it's the best ICS Rom i've ever seen, no lags, super fast (@1ghz!) and IMO completely stable, just some little bugs.

Just bought (waiting for delivery) P990, any tips?

Hi chaps,
I just managed to brick my TG01 trying to get WP7 on it (can't believe it, have flashed endless WM ROM's and had Android running on as well without issue :-( )... so I have done a bit of a knee jerk and quickly bought an LG Optimus 2X to play with until I can figure out how/if I can fix the TG01.
Obviously I've read reviews and seen feedback, and hoping I don't get a dodgy one.. but I've bought my brand new sim free for £199 from Amazon so should give me some protection if it's broken.
Any tips other than doing the 2.3 update ASAP? (until ICS official comes out)

Root it and flash a custom rom!
Stock rom sucks really, really! It's slow, buggy etc. Also, don't download the OTA update, because froyo is easier to root with Superoneclick.

Which ROM is considered the one where everything actually works on it? (Obviously people have preferences, but I'm new to this section).
Will rooting and flashing a custom rom stop me from upgrading to the official ICS later?

I think temasek's CyanogenMod KANG is the best rom available, especially combined with Vadonkas KANG kernel.

If you root it and flash CM on it, you'll obviously won't be able to get the official ICS update. But the truth is, LG is so 'great' that you likely have to wait until next year to get the next OTA. So the best thing is to root. Also, in a few weeks hopefully, CM9 will come out which is based on ICS.
I believe that you can find those apps in the market.

A tip? Buy a Noreve Leather flip for it .. they rule
Aside from that: Can I just flash the newest temasek KANG (what does KANG stand for anyway?) and the newest KANG kernel you mentioned? Or do they have dependencies that could brick the P990? And what about the other business (rils and whatnot?).
And is it as simple as rooting it (I managed with Superoneclick with the latest OTA), installing rom manager, let rom manager install cwm (will that work? I also see temasek has a KANG CWM folder in this repository), boot into cwm, wipe everything and flash the temasek rom, and after than, repeat the same with a kernel zip?
The dependencies and sequences confuse me most. On the DHD I put ICS on, the ROM came with a working kernel. But in that Temsake KANG thread it says:
"Flashable zip for Stock CM Kernel with Voodoo Sound - for p990 only (Optional)"
For a CM kernel? So do I need this installed first somehow? All very confusing for newbies to flashing like me...

The latest temasek KANG with Vadonkas KANG kernel won't brick your phone. Many people use this combination and no one has bricked their phone so far.
A great CM KANG is nothing else but a CM rom but then developed by developers outside Cyanogen Team. They use Cyanogens source code and improve or change it anyway they want. KANGs are also more stable than normal nightlies.
So Vadonkas KANG kernel is just a kernel he improved/changed using source codes from others.
Note that temasek's kang standard comes with 218 RIL. You can change this manually with the GetRIL app. Basically you don't have to change the bb. Also, Vadonkas KANG kernel comes with voodoo sound so don't worry about that.
Then flashing:
1. Reboot into recovery
2. Backup rom
3. Wipe everything.
4. Flash rom.
5. Flash kernel
6. Flash Google Apps
7. Done, reboot.
If you come from cm, then you don't need to wipe everything, just cache and dalvik. Also, if you want to update your kang rom (temasek), you can just flash it over your previous rom.

Thanks .. again "Boot into recovery" means I have to install CWM with rom manager first? I never installed CWM, so I'm not quite sure about that (on the DHD, the rooting ace hack thing did install that asfaik). And which gapps zip do I have to flash?
And maybe something about the RIL: I have no idea what it is. All I realize is, that it somehow has to match the kernel? or the hardware version? Or your area? I'm a bit confused on that as well, sorry.
EDIT: Ok ... Radio Interface Layer. A driver to the hardware's radio hardware? But that's static, so why all the various versions?

Haha no problem.
Yes you need to install CWM with rom manager first, preferably the most recent one.
Just the latest Gapps, you'll find them in the CyanogenMod wiki.
RIL has to match with your baseband so you'll have the best possible signal and minimal battery loss. The reason for al those versions is because of the fact that most countries have its own RIL. The app wil notify you if your bb and ril match. If not, flash another, if so, keep it that way .
Note: when you're coming from stock rom you need to wipe everything so also make titanium backup, just in case...

Hm ... okay ... CWM is on it, done from Rom Manager, selected the LGE Optimus "x.... booted into it ... but it says it can not mount my SDCARD (large 32 GB thing, which works inside Android .. but oiccasionally seems to behave a bit difficult.).
EDIT: Trying another SDCARD now ... an old Samsung 8 GB. Hm nope ... it can't mount that 8 GB card, either They're just ordinary FAT32 formatted cards. Guess I'm stuck for now. Could there be something wrong with the CWM Version? Rom Manager did ask about the model, but I selected the correct one I assume.
EDIT2: It seems ROM Manager is not really flashing cwm? And that booting into it from Rom Manager causes the SDCARD moutn isssue due to soemthing called "redirector"? I tried getting into CWM by all kinds of fingerpress combinations I read about ... but nothing seems to work so far.
EDIT3: Seems working now ... Power + Volume Down ... like HBoot. It also sees the sdcard now, if you directly boot into it ... let's continue this journey....
EDIT4: Arrived. Tamasek ROM + Lower Power Kernel + Gapps. Now to find out what's better than stock ROM

For those not comfortable with flashing custom rom, flashing a custom kernel may be good enough. I am using Horsepower SR2 with stock rom, took away many useless apps with root uninstaller, it is so much more damn smooth then the original, more responsive too. Played Need For Speed those kind of games, totally no lag.

Excellent... picking up some ideas already (like being able to just flash a new kernel for example ) Might do that as don't want to lose functionality.
Whatever I do I will use it at stock for a week or so, to check the phone is stable (I will probably update to latest software from LG first though to be honest).
I have also ordered a 3500mah extended battery and case cover. £4.99. Something tells me it's going to be cack, but thought i'd give it a go (I've read about the whole battery calibration thing and needing to be rooted etc, so I'll ask about that at a later time). I just was not going to pay something like £75 for a mugen 4500mah battery that was even bigger. I believe mugen could easily fit three battery in parallel (including circuitry) in a 'T' shape to give the phone a thinner profile with a bigger battery. If I was able to get a battery cover that was a little bigger and fit, I would give it a go (I've wired a fair few batteries up recently). But I digress..

That's probably the worst you can do to check if your phone is stable LG ROMs were known to boot themselves etc, although I'm not sure if this still is the case. I didn't lose any functionality with flashing and it runs smooth as a baby tush. There's even a kernel using less power etc ...

lol @ the "worst thing you can do" comment
What I meant is.. see if the phone has any problems, and see how it runs in general. I doubt LG would replace a phone with an alternative ROM if it goes wrong.
Also, without a baseline I can't determine how good an alternative ROM is. Also, with alternative ROM's on the TG01, I lost things such as being able to send/receive MMS's for some bizarre reason, and I see people saying things like "this app doesn't run, but does on stock", "no 3G vid calling on non-stock ROM"... so it's not as clean cut as you make out. I'm no stranger to hacking things about to get them to work, I'm a Dev in my job
Appreciate the advice guys, thank you

Well... it has arrived :-D Trying to decide whether to turn it on before attempting to fix my TG01, as the battery charger arrived today as well lol.
EDIT: By the way.. I have just plugged it in to do a long first charge. Is it ok to turn it on whilst it's charging and play with it? lol Also.. it's a "Made in Korea" version, not sure if that matters?
Update: Well, I've updated my phone with 2.3.4 from the official site. And so far, I'm really liking the phone Everything is super smooth, the screen is nice, and the battery life seems good so far. I only lost 5% battery last night over about 7 hours, and that's on the stock rom with the battery not calibrated on anything fancy being done, and 3g/data still on etc.
'So far' it seems like a solid phone Really don't like the way the back cover comes on an off though, that is a really poor design.

HAPPINESS!! What MOD makes you device happy, Post Here!

Since I got my o2x i have been customing and upgrading trying to find its happiness and i can honestly say I have!!! My o2x is currently whizzing around like its on an overdoze of speed. I am a heavy user, I use my o2x for everything and I sometimes feel sorry for the poor thing. I have tried lots of customs roms and kernels but this worked so well for me I have to talk about it so here it goes.
If you are still reading I assume you have already rooted your device and currently have a stock rom on it, if not please don't ask me as I am not a developer and I am sure you know how the internet (google search) works. This is what worked for me and if it doesnt for you I am really sorry but find your own happiness.
Right to business:
1. Get on CM7 latest nightly
2. Follow Temasek http://forum.xda-developers.com/showthread.php?t=1421425 and get kanged
3. Swiftextreme kernel (wish that developer comes back to xda ) http://forum.xda-developers.com/showthread.php?t=1325183
3. Match RIL with get RIL (725 v10d, Europe) worked for me
Voila your o2x is now a superphone on speed, if it works for you, you will feel the difference.
Keep your tweaks (kangs and kernels) in a folder where you can easily update and recover. You will have to repeat the steps when updating kang.....no wipe necessary.
FYI: please note that I am a user and not a developer and I cannot be held responsible for your device....READ INSTRUCTIONS properly and always BACKUP before flashing (cos it makes people get a better view lol....sorry had to).
Does it work for you? Dont thank me thanks to all the great developers of the android community who are priceless and make priceless contributions.
Post your device's happiness. What is working for you?

Congrats! Our phone is really great when rooted and flashed a custom rom and kernel on it...
One thing is... SwiftExtreme is really outdated and you should try another kernel like:
Ironkernel:
http://forum.xda-developers.com/showthread.php?t=1359307
Vadonkas KANG kernel:
http://forum.xda-developers.com/showthread.php?t=1427646
These kernels are I think better than swiftextreme

Enjoy in your new phone. You wont regret that

i know swiftextreme is outdated and thats what shocked me....i have tried ironkernel and it constantly crashes and for some reason Vadonkas kernel not working for me, phone doesnt boot nothing. I am on swiftextreme now and it is extremely stable quickly switching between apps. I can be gaming, tethering and replying to my messages everything, which with ironkernel it would start lagging and rebooting but this is really stable. Vandonkas look good and I might give it a go

Hmm these kernels should work with the latest kangs

what about camera? is it good? did you compared it with one on stock rom? IMHO low quality camera is the only, but huge disadvantage of custom roms that are not based on stock.

Yeah I know but for some reason just not working for my o2x. Wud be great to have a more up to date kernel but swiftextreme works really well. I'll keep following updates see if I get lucky

Camera is really good on cm7 plus I prefer it to stock for de hard keys option.

Congratulations, I'm really happy with my 2X too
My set is:
MIUI Moon101 + the last vadonka kernel + bb 824
The difference with the stock ROMs is really huge.

even though swiftkernel is outdated I think it is the most stable, using with latest wajkiui (2.1.20) vadonka looked interesting but my phone is constantly crashing with it :S, anyone else have the same with lastest wajkiui?

I totally agree with you, I've never had my phone this stable I don't close apps no more just switch between them. I hope it manages with the newest kangs.

I'm very happy with the following set:
- Leaked V20o with FD fix, my own battery mod, camera mod etc.
- HP SR2 Kernel
- Performance Pack V9
- very smooth V20o SQLite Libs for better scrolling
- some other mods like Supercharger etc.

cant agree with you.
i have tried cm7 and miui. both were wonderful, no complains. works perfect, looks great. except camera. maybe i need some camera mod or something else?
i'm attaching two photos. one with miui rom other with this one: http://forum.xda-developers.com/showthread.php?t=1410662. can't you see difference? both made in same conditions with same battery cover.

[Q] Are CM7 roms fullly functional?

Tonight I'm getting a new LG O2X, and I've been reading about roms and stuff. I decided to install the CM7 Kang RC1 with Etana OC kernel, but first I'd like to know if I'm going to miss features like the front camera in skype/tango, or if the app "LG Touch LED Notifications" will work, which looks very useful because of the lack of a notification led.
If that kind of features don't work, I'll probably stick to a stock based rom. Thanks in advance!

No. To have perfect combo between stock and CM7 I use Hybrid ROM.
But 1080p playback is not working for me. Anyone knows why? On stock rom (2.2.2) i worked i think.

this one?
You mean this one?

I kinda have the same question, adding something else: how's the support for the Tegra video card? If we go out of the stock rom do we lose any performance over graphics and stuff?

Unless you run a modded kernel that allows OC; there isn't much of a difference between stock and CM when it comes to performance gains (+- since stock has a lot of crap that tend to slow down the device, but can be removed of course).

Temasek's CM7.2 UNOFFICIAL Build + IronkrnL 48MB RAM hack - everything is fully functional.

I installed that rom, build 100 and everything is working perfectly I installed ETaNa kernel just because I read people recommending it but I'm still not sure about what the kernel does besides allowing overclock (which I haven't done because I haven't felt it's necessary). Any other advantages?

Just want to confirm, Temasek knows his ****! : )
I was at first rather careful with ROM's and installed CM7 stable (1 year old ROM) on my LG 2x, just to see how it will work. After few months of good use (everything working just great) I suddenly couldn't enable data & 3G networks on the device. Then battery started to show weird issues, like phone will turn on itself and show that it's charging.
10 minutes I go I gave it leap of faith and installed latest Temasek's CM7 RC2-102, MIND BLOWN. Not only it works OOB without ANY issues, fixing the battery and data problem, installation just UPDATED my current ROM to Temasek's build, which means I didn't lose any settings, apps or ANYTHING.
Just install Temasek's builds, you won't regret it.
BTW, how to donate to Temasek, I couldn't find DONATE button?
Cheers!

Thank you.
No one rom is perfect. Soon you will find something not working or something u don't like. Overall cm7 is a very good rom.
Btw I don't ask for donations so u wont see any donation link.
Thanks.

everything is fully functional on cm7 since the fm radio was fixed (and that was a LONNNNGGG time ago)
only things that can be glitchy are the completely NEW features them devs are makin up
and no you dont loose any kind of graphics performance or w.e when going to cm.
yes, front camera also works...

Well, I think video calls don't work, as that is a function of the stock telefone app, but I might be mistaken.

not only you dont lose, but you also gain... best stock rom+best stock kernel vs best cm7 rom+best cm7 kernel cm7 wins everytime by a big difference, and in graphics some cm7 combos even boost your fps's a bit

Go for Django Manouche stock rom, all works, crap LG apps gone and aroma installer, if cm temasek
