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.
Sori m jst new here..jst b0ught my f0ne 2 m0nths ago. Flashed r0m: gingercrime ITA, flashed kernel: ver 2.6.35.14 v6. And iv overclock my fone 245-710Mhz, smartass. fone: lg optimus one, running on gingerbread 2.3.3
Many thanx xda developers..!!
Hi, guys.
To save everyone's time, I'll try to keep this as simple and to the point as i possibly can (which for those of you who know me, is a bit hard... lol). I also want to thank each and everyone of you who takes the time to answer in advance.
So, apparently, Samsung rolled out GB for TPH sometime around last week or so. However, KIES refuses to update my phone, for whatever reason (I suspect it may have something to do with when I tried Darky's ROM, which messed up the product code, but it may be something else entirely). No matter what I do (including a factory reset to stock TPH 2.2.1, which is what I have now), the "upgrade firmware" option is not available.
I've just about had it on waiting, so I'm ready to take matters on my own hands.
I'd like to install either the stock TPH 2.3.3 firmware (I9000XWJVH/I9000OXXJV9/I9000XXJVO/I9000XWJVH) (I'm missing a download link, though), or finally move on to something a bit better, like 2.3.4 with the following characteristics:
- Near stock (some ROMs I've seen are way too customized, I actually don't mind most of the stock stuff, including apps people don't like using, like AllShare and similar);
- UV and UC-ready;
- English and Portuguese input (Swype included) and menu languages;
- Preferably, Portugal-compatible CSC, (standard PT-available modem seems good in terms of battery life, so no special requirement there);
- If available (wishful thinking), SIP and Skype integrated in the dialer (I believe SIP was a 2.3 feature, right?);
- Full Market access;
- Easy to upgrade, if possible.
Also, I'm perfectly OK with a 2-step approach (like loading 2.3.4 and then a custom kernel).
OK, I think that's about it. With so many ROMs available, I get lost on the different features, so I need help from people more experienced than me.
So, fire away, guys. What are your options on this one? And again, thank you in advance!
Miguel
Check out the following links:
1 SIP integrated for deodexed Gingerbread ROMs from Samsung (2.3.3 & 2.3.4)
2 [CWM and Odin][Latest ROM: XXJVQ, UGKG3, XWJVN] Deodexed stock firmware collection
3 Juwe's Smart Edition > v5.3 XXJVR Based On Official Android 2.3.4 <
4 Juicy Ginger 3.1
5 XXJVR HYBRID v 2.0
6 MilkyS MOD
Skype in my knowledge is not integrated in to the dialer in any of these.
OC/UC/UV all are kernel features and all the custom roms have good kernels. Best OC/UV kernels are Semaphore,Talon & Galaxian. U can use neldars SGS kernel flasher to change rhem any time for a mix'n'match.
The last 3 are custom roms with all the essential apps, full market access, SIP integration and most of the stock apps.
I think Hybrid will be a good choice for you as its heavily loaded.
Milky Mod has swype in many languages.
Check them out and hope you find your pick. Hope this narrows down ur choices.
P.S - My favorite is Juwe's Smart Edition! Ultra stable, Smooth & Fast
Thanks, DonVito!
That is A LOT of information to get through, all right! I'm checking the pages to see about supported languages, but right now MilkyS seems my best option, especially because it seems the only one where Portuguese is a Swype language, and it may be installed directly over Froyo.
I'll check it out, and also the apparent absence of a product code on my phone (which may be why KIES refuses to upgrade my firmware, and a proof messing with Darky's ROM might not have been such a good idea...). I'll probably try re-setting my product code to TPH and check KIES, but I'l probably go ahead and jump directly to 2.3.4 , these custom ROMs seem to be very good.
One last thing, though: given my current firmware (I9000XWJVH/I9000OXXJV9/I9000XXJVO/I9000XWJVH, I forgot to specify this one is not the current stock TPH GB firmware), which firmware should I get from Samfirmware? There are WAY too many options, and I simply cannot get the hang of translating standard Samsung firmware codes to the SGS firmware packages...
Again, thanks for the input!

Hi everyone.
I still Have Nova ROM v8.
But i've been paying attention to the ROM Thread, and i see that 2 main ROMS stand out, Zeus and Marvel.
I wanted to know which one of this is the more stable and better one.
Comparing Nova to Zeus , and Nova to Marvel , which one of them got better battery life?
regarding performance which one of those 3 is better?
Best regards,
bullseye
Install zeus v3n.

The problem i have is i need to upgrade to 2.3 now my phone checks as a V10D does this mean i can't install the V20x ROM's due to them not being compatible?
Ideally i wanted to keep with my stock ROM and just update but i installed CWM so i can't do that and looks like i'll need to flash to a non-carrier ROM which i have heard causes issues due to people removing all the stock apps from LG etc.
So can i even install the V20x's or are those a no go and how long before we get a nice clean near stock ROM with root because i'm really not a fan of the ICS look

1) i might be wrong, but i dont think it would be a problem if youre flashing up from v10(froyo) to v20(gb)
2) problems arising from custom roms are not directly caused form removing stock lg apps, usually it arises from the extensive tweaking and modifications the dev applies to make the rom better
3) if you want just a rooted stock v20 you could probably ask the devs nicely or sth since they based their own roms from the stock v20 (well most times) or you could prob try asking Nooby for his nandroid
4) if you want to install a custom rom but dont like the ics look there are a few options actually,
- Redy's Repack of the Official v20n
- Zeus's stock ui is pretty close to stock gb (sans the blue themed icons)
- There is also Achyut's Prada Themed Rom

There are still a lot of bug my friend WIFI adress doesnt show up, battery drain is faar to high, laags sometimes, freezes sometimes,... You will still notice this. So a stock ROM will at least until now be the better choice, although I also use CM, cause I like the look

Hi there!
I must say I'm very disappointed with my 2 year old Galaxy S I9000. Reboots, stuck, UI bugs etc.
I tried any possible 2.x.x ROMs (gingerbread). It works fine ~2 months, then start to randomly reboot, lag and etc.
I'm thinking about moving to ICS or JB (??) ROM. Preferably clean ROM from Google with/without 3d party developers modifications (without any samsung crap, or touchwiz or whatever). I though about CM9 but now I read that Slim ICS is better and more stable.
The first thing I need from a phone, is to be a PHONE! i.e. send and receive calls and sms. WiFi and 3G is very important, GPS is very important. Those are the important-mandatory-must-have-must-work things.
Secondary things I want from a phone is to be a decent photo camera (rarely take videos, but not going to give up on this feature), music player, support for external sd card.
Languages does not matter to me, I use English interface. Ability to support RTL languages correctly will be a bonus. Preferably a clean ROM without any forced application (like custom launchers or etc, give me the opportunity to select my launcher please) OR a ROM with pre installed application but with ability to remove them.
Any suggestion to any ROM and kernel combinations will be appreciated!
Thank you a lot!
You can try downloading two roms at a time and put that in your root of sd, so in case 1 fails to qualify you can quickly switch to another rom thru recovery. I'm using aokp for my nexus, maybe its good for galaxy s too.. it depends on personal taste.

Try the latest CM9 stable rom release. Much more reliable than Sammy stock roms imo
I9000 CM10 nightly
I would recommend CM 9.1 as well. It works great and is really stable.
Sent from my Gameboy Color
If you want good battery life, stability and performance, try CM9 Stable, even better is SlimICS. From JB roms CM10 nightly... (also good ICS roms are eg. AOKP, TiramiSlim, RemICS...)
Thanks! I think Ill go with CM9 (with stock CM9 kernel) and as backup option Ill have Slim ICS on sd card.
Other suggestions will be appreciated!

I recommend JB C-RoM BeaN v1.3.4 (the latest v1.3.5 is for release already). All system applications you mentioned above are working fine, super fast and smooth, no lags. Also no Samsung Apps. Google Apps are in a separate Zip file so you can choose to install them or not.
I'm using this RoM now and I can say this is the best RoM I have ever used compared to GB, ICS, and other JB Roms I've flashed.

Very good for daily usage...

Either Gamerzrom v11 (Gingerbread) or Team nyx rc5 (ics). I'm on gamerzrom v11 and I'm waiting for v12.:laugh:
I would have to submit my vote for Gamerz v11. I have been using it for a really long time and have had no issues. Right now I'm almost at 7 days battery life with data turned off when I don't need it.
I'm looking for a list of stock G800F roms which are bloatware free and not branded in any way. So far I have tried only one, South East Europe (SEE) which is downloadable from sammobile and is completely clean from any branding or bloatware. Which other ROMs are like this?
So far I've found the following clean stock ROMs. The list is getting updated as I test, feel free to contribute.
- South East Europe (SEE) - as stock as it gets, default language is English and can be changed during initial setup
- Germany (DBT) - no branding at all, 3 apps that can be uninstalled, default language is German and can be changed
searching for this too!
Slim6 in ROM section is for F variant. It is very light Samsung free, Google free. You need GAPPS to get Google Play for that ROM. It's really smooth and pretty much everything works.

what about battery stats or camera bugs? is it solved in slim6 rom?? did you find any bugs or is completely stable? thanks
I didn't have problems with camera but I don't use it a lot. Battery life is okay but this is custom made so expect it to lose power a bit faster. However it's so much smoother than what Samsung made that you won't believe your eyes.
its important for me that the standard camera works fine, read everywhere about fc crashes ans so on...

As far as I know it works fine on untouched version, but he made another version that's 2.0 atm and I heard that one has problems but if you install custom application for camera you're good. As always these are custom ROMs so you need to accept risk and be ready to screw around if things go south but from my expirences it's pretty good.
