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!
So right now I'm running Task650s AOKP with Siyah Kernel, but an old version, thats still Android 4.0.4. In addition, I only have CWM 5. A lot of the KK ROM threads say that CWM 6 is required (and some JB ones imply the same thing, or tha I need JB bootloaders), but the one I want to flash (PACMan) doesn't have such a warning, but I'm still a bit apprehensive. Will I be fine if I just wipe, flash PACMan + GApps and reboot? Or is there an intermediary step I need like flashing a new kernel, and if so which one do I need?
Thanks guys

Well pacman isn't based on kitkat so I think you're good to go, the newest nightlies for that are still based on jellybean right? Or has it changed? I haven't downloaded one in a like two weeks.

Yes, you will be fine, as long as you install a JB kernel first (either STI or AJK 4.9 AOSP). I would suggest you install Milestone 1 (the download link is labeled PAC Release), instead of the nightly. Nightlies have a reputation for being finicky at times, so if you want stability you'd be better off sticking with known stable releases.
And don't forget to flash the gapps either, or you'll run into other problems.

Alright, sounds great. Thanks for the help, I'm downloading now.
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?

Well that's what I thought, but why then would I be using an OMNI kernel (3.0.64-OMNI-g5f47648) when I have flashed the last three AOKP nightly ROMs that have come out? Or am I missing something here?

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.. ??
Yo! What do you guys think is the best combination to get reasonable battery life and good performance? Im getting 59k on antutu using AICP ROM and stock kernel. Do you think i could get more with some custom kernel ?
I am just using stock since Pure Android is what I want, with ElementalX kernel. Using ElementalX on my Nexus 6, Nexus 9, and GPE HTC One M8 and love it. I look forward to Xposed working with Android 5.1 and N9 being updated. I used to flash ROMs, but on Google devices Xposed is more then enough.

I'm on Dirty Unicorns with Fire - Ice kernel. Insanely stable and the most functional of the ROMs I have used.
As far as just running a kernel, yes you certainly can just flash the kernel w/o changing to a different ROM. But what's the point in that??

Sorry when you asked the question, I didn't realize you were already on a non stock ROM. AICP already has it's own customized kernel. Yes you can flash any other custom kernel in place of the one which comes with AICP.
I have a Samsung Galaxy S2 which I am using for 5.5 years. Some months ago, I upgraded my phone to Android 4.1 (Jelly Bean) (Using Kies). Officially, that is the last update for my phone. But I still want to upgrade via custom ROM.
The configuration of my phone:
Chipset: Exynos 4210 Dual
CPU: Dual-core 1.2 GHz Cortex-A9
GPU: Mali-400MP4
Internal: 16 GB storage, 1 GB RAM
Battery: Removable Li-Ion 1650 mAh battery
Display: 16M Colors, 4.3 inches Super AMOLED Plus capacitive touchscreen,
480 x 800 pixels, 5:3 ratio (~217 ppi density)
Which version of Android will run smooth in my phone ? Will upgrading slow down my phone?
Please help ! Thanks a lot.
Normally, the best performance is reached by stock ROM - there only are exceptions at Samsung.
In general, the newer the ROM, the more resources it needs. I think the best performance is possible with Android 4.4 KitKat. Marshmallow was faster than Lollipop in my experience, Nougat is slower than the both previously mentioned.
So if just the speed counts, try KitKat, if you also want a newer Android, go for Marshmallow. This is just my personal opinion.
i stay on Ehndroix , more fluid and good for games and battery without kernels. slim KK

It depends on your needs.
I use my phone mostly for phoning (by mobile data or telegram), mailing, chatting and surfing. I did not install any g-apps. For me Android N is very smooth and reliable.

Does anyone know if there are KitKat or Marshmallow ROMS available that are patched for the KRACK WiFi vulnerability?
Currently running LOS 14.1 on 7.1.2 and the latest nightly has been patched for KRACK, though performance is not as smooth as I had (Naively?) hoped

Hi,
Upgrading your phone to the latest version might cause some instabiltity and performance issues, but it entirely depends on the rom and kernel that you'll flash. Most Kitkat based roms will do good, currently using this one and so far no issues at all.
Regards,
Thank you for the suggestion. I am currently using this custom Nougat-compatible kernel, what is the process to flash an older KitKat compatible kernel and ROM (I.e. going backwards from 7.1.2 to 4.4.4)

You can do a complete wipe then install, although I only tested this on LOS 11 so I don't know what result it will give on other ROMs...
You can also repartition your phone storage then install a Kitkat compatible recovery then install the ROM that you like.
I'm planning to test the downgrade using LOS 11, downgrading from LOS 14.1
How do I repartition the phone storage?
Do you have any suggestions for a KitKat compatible recovery and kernel?
Thanks

You can repartition your phone by using lanchon's repit method but make a backup of your internal storage first. As for a Kitkat compatible kernel, you can flash Saber's DorimanX kernel for LOS14.1 and use TWRP recovery from the IsoRec thread.
You can also flash LOS11 without repartitioning, just make sure you have the latest recovery on your phone to avoid encountering problems.
I have the latest TWRP recovery. What would be the difference be in flashing LOS 11 without partitioning, as opposed to using lanchon's repit method before flashing?

There's no big difference really, it's just that some ROMs don't support different storage formats such as ext4/f2fs (and sometimes, the modded preload too)
If you have the latest TWRP recovery, you can flash LOS 11 right away - just don't forget to do a full wipe.
Just to clarify that I have correctly understood your instructions:
Flash Dorimanx kernel for 14.1
Flash LOS 11 ROM
Thank you kindly ^_^

You don't need to flash DorimanX if you have the TWRP recovery, just flash away.
Hope you enjoy your new ROM!
Is a full wipe:

/partition
and Dalvik?

Root is disabled by default in LOS 11, to activate it you need to go to:
Settings -> About Phone then tap the Build Number seven times
Once it's done, press the back button and select Developer Options, scroll down a bit and find the Root Access option, then select "Apps" or "Apps or ADB" (depends on you, there's not much of a difference anyway)
Thank you
Do you have any CPU governor suggestions (InteractiveX?) and frequency suggestions?
