Hey guys. I just got my unlocked S2. After looking around I like the default apps and stuff. Kies Air is awesome too. If I flash do I lose those apps? Am an experienced user. And think yeah but dunno. Worth flashing a ROM? stock stuff is nice.

I have been thinking the same to!
Hello there. It depends on what you are flashing. There are two kinds of roms, those based on official sammy roms and ASOP roms (like cyanogen) which are clean and built from scratch. If you don't want to lose the other apps I recommend you flash a rom based on official sammy roms or just root because usually ASOP roms don't contain much and they can't use any sammy based programs/apks.

Well for some reason with this phone I like Samsung apps. So no ASOP this time. Weird. Well what are some good Samsung custom ROMs?

Yeah, I like them too. You could try:
Lite'ning Rom
Exynos Extreme
Criskelo Rom
I've tried these and they're good. Samsung goodness but faster and snappier. Enjoy flashing.
Basics are you root if you need root it does not make your phone go faster .
Custom roms may or may not wipe apps its all in the description of each rom .
Little performance difference between custom and stock rom .
jje
Root- It's a must imo.
A Custom ROM- Depends on how mad you are about them. I am not.
I agree just root with cfroot if you like the stock apps etc.
Personally I think KI8 is worth a look.

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

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

Highly customizable. You can overclock, undervolt, theme, use different launchers. To me they're faster too.

What about if I install a custom kernel, but keep my stock rom? Is there any benefit at all?
To clarify: I'm on i19100 4.0.3 which I've recently rooted. Thinking of installing Siyah 3.5.2 but for now I want to keep my stock (Bell) ROM. What do I stand to gain when I get the Siyah kernel, if anything? Or is the kernel really *only* just a prerequisite to get a custom ROM?
Thanks!

with siyah 3.5.2 installed u can be sure that no brick bug for u

But there's already no brick bug on 4.0.3 right? So... what exactly would I gain with the Siyah kernel?
The only thing I can think of is CPU/kernel modding

One BIG reason I'm on stock ROM and KERNEL is that currently no custom Kernel supports MHL (please correct me if I'm wrong)
For me this is a big problem as I'm always watching movies and playing games on my TV with my phone

It's the ROM, not the kernel, that determines if MHL fully works.
Apparently video works with AOSP, but not full mirror of the display.
However, if you want full mirroring, you'll need to be on a stock Samsung based ROM.
That said, you can still run a custom kernel, such as Siyah or SpeedMod, and MHL will still work as long as you remain on the Samsung based ROM.
I'm currently running stock XWLPX with Siyah 4.1.4, and MHL works fully for me.
Hi I would like to ask whether rooting the phone is the same as unlocking bootloader. Thanks!
No, it's not.
Rooting allows you to view and edit system files.
Unlocking the bootloader allows you to install custom (non-official) kernels.
So rooting my phone and unlocking the bootloader is 2 different issue?
Or does rooting my phone actually unlocks my bootloader as well?
Rooting does not unlock bootloader.
Unlocking bootloader can help root your phone (installing a pre-rooted kernel, for example).
Is it then possible to install a custom firmware without unlocking the bootloader or will there be problems if I install a custom firmware without unlocking the bootloader.
These two custom ROMs are the only ones that can be installed without unlocking the bootloader.

OK THANKS! SHALL GO CHECK IT OUT And can I ask, does the phone by itself already have a kernel? If it has, what is the use of installing another one?
Stock ROMs have their stock kernels.
Custom kernels can add some features, such as (for example) the chance to overclock the CPU. Almost every custom ROM needs a custom kernel to work properly.

Wrong. Custom ROMs do not need custom kernel to *function or work properly*.
The custom ROMs are installed at the Read Only Memory of your phone.
For that, you need to use an installer which has to be somewhere outside the Read Only Memory. Only such location on your phone is the kernel. So a custom kernel does nothing but adds an installer outside the Read Only Memory (that is the CWM Recovery).
Now to intall a kernel, you need an installer outside of your Read Only Memory as well as the kernel. That's the PC, and the installer is Flashtool. So, flashtool is used to install custom kernels on your phone.
Note: The two ROMs which can be installed on locked bootloaders are exceptions to this rule.
Thanks,
Rick

If it were like you said, any custom kernel could work with any custom ROM, as long as it has a Recovery to flash the ROM. There are different custom kernels because there are different ROMs, and each custom ROM works only with one or more custom kernels, but not with everyone. If you were right, one single kernel with recovery would be usable for every custom ROM.

Yea. It would be. Infact it is.
However, ROMs like CM9, which are NOT based on the stock ROM will not be able to work on the stock kernel. It will require a kernel which has been designed specifically for CM9. On the other hand, we had seen MiniCMSandwich, which looks like CM, but is based on stock ROM. This will work on any kernel that has a custom recovery. MESA, Rage, X, Stock Exteneded and so on...
So, to put it in other words, suppose you plan to flash an HTC Phone ROM as it came in the HTC device on your Xperia Device. You plan to just change the drivers. You will need a kernel which is designed for the HTC ROM.
But, if you, on the other hand, start with the Xperia ROM and change the aspects of this ROM into the HTC ROM's, you can make the ROM work on any of MESA, X, Rage or extended.
Thanks,
Rick

Stock extended, yeah. Try to run MiniCMSandwich on Gingerbread stock extended kernel. Will it work? Of course not. All the kernels you named are based on stock ICS kernel, so it's simple to run ICS based ROMs on them. This doesn't mean that every kernel with recovery can make them work

Stock GB is to Stock ICS is same as Stock Xperia ICS is to Stock HTC ICS. They are different ROMs. Completely.
The ROMs have instructions according to which it behaves with the kernel. These instructions are all same for kernels that are based on stock ICS. So if you want to try any ROM that is based on stock ICS and such kernel will do.
But CM, GB, HTC ROMs and so on, are completely different.
Say you want to port an HTC ROM to Xperia ICS. You can do the following (I am taking example of the bootanimation file)
1. Simply change the bootanimation.zip file at /system/media of the stock ICS ROM.
So your ROM is based on the stock ROM itself. You just change the files, not the way the files are accessed. You do not even change the way the kernel is accessed. So any kernel based on stock ICS *with recovery* will do.
2. Change the whole Read Only Memory Partition.
This makes all the files replaced, the way HTC has made the ROM. This time you will need a kernel *again with recovery*, built to be accessed by the very specific ROM.
Thanks,
Rick

I'm new to the world of Android and am loving my razr maxx. Right now I am using stock 4.1.
It is in my nature to tweak and customize and thus the prospect of using a custom ROM is enticing..... but a few questions.
1. What are the advantages over using stock jelly bean? disadvantages?
2. It seems like there's a plethora of different custom ROMs on this site. How do you go about choosing one? CM seems to be pretty popular... Why?
3. How do I learn to flash it correctly so I don't screw up my phone? I realize there's a plethora of info on this forum but sometimes it's overload and it's hard to find what I need to know.

Hi, The advantages of using the stock rom is that is more stable (sometimes) than a costum rom,but the custom maybe is more fast and smooth and have a better customizable expirience..
i suggest the cm 10.1 becose it's very fast,up to date and realy customizable....
One of the best thigs with the razr is that you can install 5 system at the same time,so you can try different rom without delete the stock one
You have to;
Get root http://forum.xda-developers.com/showthread.php?t=2230140
install a costum recovery https://play.google.com/store/apps/details?id=com.projectlense.bootmenu.manager&hl=it

I think all device with bootloader locked have an recovery like this,but safestrap or boot menu manager are only for some motorola device
So I've tried a bunch of different ROMs (CleanROM, Alliance, Beans, CM, OMNI, "Stock", probably more), but I've never really understood kernels. It seems some custom ROMs have a kernel built in (or several to choose from via Aroma), while others do not. Right now I'm running AOKP (4.4.2) with the kernel from OMNI (3.0.64-OMNI-g5f47648), presumably because that was the previous ROM I flashed with a kernel. I'm not too concerned with customization, more with stability.
I've been having a few minor bugs and crashes and I'd like to try perhaps the stock kernel to see if that might help, but I have some questions:
1) Does it matter when flashing a kernel whether the ROM is TW or AOSP?
2) Are there multiple versions of kernels that correspond with the Android version of the ROM?
3) What's the best/easiest way to flash a kernel, presumably through the custom recovery like a ROM?
4) Where can I find the stock kernel? I found this thread (http://forum.xda-developers.com/showthread.php?t=2610870) with the stock MJ9 kernel, but going back to my first two questions I'm not sure if it would work with my current ROM.
Thanks ahead of time for any insight anyone can provide.

1) Does it matter when flashing a kernel whether the ROM is TW or AOSP?
Yes. TW and AOSP kernels are different.. The only one, that I believe, that can be used with both is Devil kernel for Dual Booting
2) Are there multiple versions of kernels that correspond with the Android version of the ROM?
Yes. Usually every version of android that gets updated.. the kernel does as well
3) What's the best/easiest way to flash a kernel, presumably through the custom recovery like a ROM?
Yes you can flash kernels through a custom recovery. Most of the time they are included with the Rom that you flash. A lot of the custom ones out have flashable zip for you to flash them through a recovery.
4) Where can I find the stock kernel? I found this thread (http://forum.xda-developers.com/showthread.php?t=2610870) with the stock MJ9 kernel, but going back to my first two questions I'm not sure if it would work with my current ROM.
No this will NOT work with a AOSP rom.. The kernel will be specific to that ROM and every other TW 4.3 ROM, but NOT AOSP

Maybe he uses that kernel.. AOSP kernels, I believe are pretty similar.. I may be wrong, I am by NO MEANS a kernel guru..I would open you zip of your ROM (AOKP) and take a peak.. if there is a boot.img than it flashes a kernel.. and if your says OMNI then thats the kernel the dev has used..
Stock
If I'm on the stock rom and want to go back to the original kernel can I just restore the boot img in recovery?

Thank you sir. It worked just fine.
I have a noob question, I'm currently using n3bula 3.9 custom rom and it's been running fine for a while. I noticed that users chose the agni kernel whereas I chose the stock one. So my question is, is it possible to flash just the kernel from recovery without losing my data? I've spent so much time and effort customizing my phone, therefore, I just want to change the kernel. Any help will be appreciated. Thanks.

I would think that as long as it doesn't break anything you should be fine. Probably do a backup first if you're worried about it.
Thanks for the response Michael, however, that was the response I was dreading! I'm actually worried I'll lose my WhatsApp and Viber accounts because even if I backed up my data, I'd still have to register my old WhatsApp and Viber numbers all over again which I don't have anymore.. ??
