Hello,
I've been frequently checking the web for the official JB update and everything i've always have read is that it will be released soon, not OTA yet so I'm going a bit desperated about having JB on my s2. I'm actually on 4.0.4 official (yeah, the brick evil kernel) and I'm pretty happy with it but I'm very curious about all those 4.1.2 custom ROM's roaming around the net.
What's your advice for this ROM's? Are they worthy to install them at this point in my device? Are they fully working with all the JB functions? Or at this point should I wait for the official ROM and give chance the community to work in ROM's based on it?
Greetings, any advice/hint will be much apprecciated.

Fully working now, yes.
Now go out and do some reading so you can take your pick.

Well regardless of what above poster says, no they are not fully working. However the bugs that are present are not serious and most people will not come across them.
However I would HIGHLY recommend that if you flash the leaked stock rom or a custom one based on it you will need to flash Joboo kernel as it fixes the most annoying bug which is the lock screen delay which is really bloody annoying. It also increases battery life as Philz kernel is bad for this. You can also freeze non-needed stock apps to increase life more.
By the way incase you didnt know, since you have 4.0.4 stock you dont need to worry about the brick bug if you simply flash a custom kernel like Siyah instead of keeping stock.
Okay, they are not fully working I guess. I can always be wrong.
Still, reading time.

Yeah, actually I did know that I could flash Siyah to avoid the brick risk but I just wanted to do it all at the same time, I mean, root -> flash Siyah ->jump to another custom ROM. That's why my question about waiting for stock 4.1.2 for more stable ROM's before flashing and rooting :victory:

You dont need to "root" and then flash Siyah, Siyah gives you root.
If coming from stock rom/kernel all you need to do is....
Flashing custom rom:
Flash Siyah kernel via ODIN
Reboot into custom recovery
Wipe data/factory reset
Flash rom zip (and gapps if using CM based rom)
Reboot device.
Note that flashing a custom rom will come with its own kernel so it replaces Siyah.
Flashing Stock Rom:
Flash stock rom via ODIN
Flash compatible custom kernel
Note: If you using leaked JB you should use nothing but the Joboo kernel. If flashing GB or ICS rom you should use Siyah.

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.

cheers guys i guess custom seems the way forward, just need to research the changelog of each rom that takes my fancy
thanks again guys !!
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!

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.
H all
I've had quite a bit of experience with modding my old SGS. I have recently acquired a S2
Anyway it's running stock 4.0.4 can i just go ahead and flash SiyahKernel? Then i can install a custom
rom (MIUI). Or will i have to root before flashing Siyah?
Not a complete noob lol.but seems a little different to the old S
Cheers
Siyah is an already rooted kernel, so as soon as you install Siyah on ur device, u'll also get root.
Try flashing a safe kernel asap, since your stock 4.0.4 is highly dangerous when it comes to wipe data. In fact, your device will get an instant brick if you wipe.

I'm looking to update from Android 4.0.4. My SGH i777 is rooted from last year.
I have the clockwork mod recovery installed from last year. Using AOKP I think.
There's ROM's for 4.3 but I don't see any kernels posted here. Can someone point me in the right direction? Apparently the sg2 has left the limelight for a while now.
Once I get the kernel updated, does anyone have any good ROMs to recommend?
Thanks
ps You guys are an awesome community.
Which rom is a personal matter. You should try them yourself to see what you like. If you want Samsung Touchwiz based firmware, the latest version will be 4.1.2. To get 4.2.2 or 4.3, you will have to go with one of the AOSP based roms.
Since you have a custom kernel with CWM Recovery, just pick the firmware you want to try and flash it in recovery. You don't need to install another kernel first.
Wait, so all I have to do is pick another ROM? That's it? No firmware update?

firmware update? no. Whether 4.0.4 or 2.3.whatever, you already have have root/cwm; all that's left is a some recommended housecleaning*, then flash whatever ROM you want.
*either:
rom-cleaning-script
or:
factory reset
+format system
Mind = blown. Thanks so much guys!
In my experience with custom ROMs, I found that ShoStock3 v4.0 and UCMD8 v2.2 COOKED give the best battery life and stability, but I use the stock kernel for ShoStock and AJK v4.9 for UCMD8 COOKED. CM/PA/AOKP have given me subpar results in terms of stability and, most importantly (for me anyway), battery life. This is not to say that those other ROMs are bad, but for me, those haven't been working out. Your mileage may vary. Just my $0.02.

So you're looking for a rom. The rom you use will all depend on the type of software you like. If you like touchwiz, I recommend Shostock 3 4.0 or the Cooked Rom. If you're looking for a AOKP Android 4.2.2 rom, then I would use the Resurrection Remix rom, but remember, all roms differ on every phone. Not everyone gets the same results. I wouldn't use a 4.3 rom because its fairly new and pretty unstable on some phones, but if you really want to, I got the best results on the Carbon rom, but the battery life wasn't so good. Also, a lot of the 4.2 and 4.3 roms require you to flash gapps, which are the google apps for you phone. If you're looking for kernels, the usually come with the rom you download, so you don't really need to get a kernel. If you really want the extra customization and tweaks, there are some kernels out there, including AJK, Jeboo, and STI, that you can flash. I personally use AJK on a lot of my roms because I found it to be the most sucessful. I am running Shostock 3 with jeboo kernal right now. Shostock 3 has good performance, stability, and battery life and is touchwiz. So yeah, keep all this in mind when flashing a kernal. You don't to connect your phone to the computer or anything to flash a kernel. If you're rooted, you just have to have the rom in your phone storage or SD card and go into clockworkmod recovery and flash. Hope this helps and good luck on finding a rom that's right for you!
Hi everybody.
As stock ICS has better performance than stock JB, to update to CyanogenMod from stock 4.0 is better than do it from stock 4.1?
Excuse me if this question is answered in the forum, I don't find it.
Regards.
Those are two different subjects.. There's no relation between a stock rom's performance, and the speed of 'better way' ro flash a custom rom. However, there are things to think about when coming from stock 4.0.4., but I assume you've read the guides and seen them (brickbug etc.). Good luck.
Thanks for your answer.
For your reply, I understand to install stock 4.1 and then install CyanogenMod is less problematic than install it from stock 4.0, ¿right?
I don't have the phone yet.
I will read more & more before install CyanogenMod in this device (I readed about installing problems with this cellphone at CyanogenMod's Wiki).
Thank you again.

You just have to search for information about the brickbug that can appear in 4.0.4. Read about it and avoid it, than it is 'safe' to flash any custom rom (it always contains a risk of course).
May I ask you why you would want to flash CM immediatly? Stock JB works very good on the SII.

While maybe it's very good for you, it isn't good for me. Stock ICS was acceptable for me, but Jelly Bean sucks.

Maybe I used a S2 but not my S2.
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

Thanks for the explanations, that helps tremendously. I'm confused now, however, because several people on the AOKP thread (http://forum.xda-developers.com/showthread.php?t=2453566) claim to be on "stock kernel". Is there a stock kernel for AOSP that I'm missing?

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.. ??
