[Q] Flashing New Kernel - T-Mobile Samsung Galaxy S II SGH-T989

Hi I was wondering what is the best Kernel for the T-Mobile version of the SG2 when it comes to battery like and performance. Right now I am running CM10 4.1.2 and its stock kernel that comes with the ROM. I am fairly new to this whole process so if I flash a new kernel do I have to wipe everything or just the cache? Please help me. Thank you

You shouldn't need to wipe everything but I do if I can. Ocd.
Also, some ROMs are not compatible with all kernels and vise versa. There is no best kernel IMO. Just test em out.

Like said before, there isn't a best kernel. But read through the threads and but can see what each one does and it's problems.
I would recommend lightning zap but u have to do some digging in the pages. It's stable, best performance and battery life
Also u don't have to wipe anything but it's recommended to flash after a new rom flash

[Q] Noob Question lol

What is a kernal and what does it do? Is it any different than a ROM? And how do you flash/install a kernal. I've flashed a few roms on the past few phones but I still have no idea what a kernal does.....any help appriciated..
You install a kernal simply by wiping caches,(cache and dalvik cache). Custom kernals allow you to do things a stock kernal wouldnt allow. There are some great developers of kernals here on XDA. You really just need to Search the forums for all of your answers, even google it. Once you do learn what a kernal is,you will be able to enjoy the full, or almost full, potential of your phone. Good luck!!
In a nutshell a kernel is the "heart" of the OS. It's really simple to flash. You start by making a nandroid that way if something goes wrong you have a backup, then wipe cache/dalvik 2x each, after that you can flash the kernel. It's a rinse and repeat process.

Quick question. I see that they are labeled like [sense] and [AOSP]. If I'm running MUIU as my rom right now, would I use an AOSP Kernel or does that matter.

Definitely matters. You need an AOSP kernel like Tiamat or Savaged Zen. I had good luck with Tiamat, but I'm running the stock kernel at the moment.

It wouldn't be a good idea to you a Sense kernel on anything besides a Sense ROM, or you will get a boot failure. I believe that MIUI use AOSP kernels.

Kernal ??

Is it necessary to flash a Kernal after flashing a custom rom ?
I am thinking of flashing CM 9 or Liquid Rom. Which is the best kernal to flash with them.
-The correct spelling is kernel.
-It is not necessary to flash a new kernel with a rom. In general roms will package the stock kernel unless they note otherwise.
-I am personally a fan of leankernel because of the mission statement behind its development and the accessibility and speed of its update cycle.
Nope. Custom roms have kernels included, so you are not required to download a separate kernel. However, some kernels run better (ie, more fluid, less heat, reboots, etc) than others on the same device. It all depends on the silicon in your phone. If you plan to run cm9, I recommend sticking with the default kernel. If you're going with Liquid, use imoseyon's leankernel (the default) or franco kernels.
Edit: BTW, I highly recommend franco's kernel app, especially if you are new to the scene. It can download & install either franco or imoseyon kernels, making kernel flashing stupid easy. It also lets you overclock & undervolt, change governors and tweak color settings. And it is the easiest way to keep up with nightly/experimental builds. Not to mention it shows your support and encourages more development.

i say try them all, but for cm9 i recommend fugumod.

Thanks you all for your suggestions ...
finally going to try Liquid Smooth 1.25 (http://forum.xda-developers.com/showthread.php?t=1555667)
along with Franco.Kernel (http://forum.xda-developers.com/showthread.php?t=1367341)
...... One last question Which Franco Kernel to flash there are Milestone 2, Milestone 1, Nightly ??? Whats the difference between them ?
Also when installing extras for liquid smooth do i need to wipe everything again .. I am new to this flashing stuff
and does Liquid Smooth comes with a kernel if so which one ?
Latest milestone is the most stable. Nightlies are experimental. And no need to wipe.

@cldwar
Liquid + franco is a great choice. Liquid is an extremely polished rom. Very, very smooth with absolutely ZERO lag (it is called Liquid Smooth for a reason) and lots of customization & tweaking options. franco kernel pushes the smoothness to another level. Liquid & franco are both awesome devs who have been tinkering with android for a long time, and they both know their stuff.
Liquid comes with imoseyon's leankernel, which is a solid kernel (obviously, or Liquid wouldn't have included it in the rom). imoseyon is another well-known & respected dev that churns kernels at a dizzying rate. He must develop in his sleep. A lot of people prefer his leankernel, and you really can't go wrong with it. But like I said before, it really depends on your device. Your phone picks the kernel, not you. Milestones are the most stable versions. Nightlies are bleeding edge experimentals with the latest patches & tweaks that may or may not improve battery or performance. Since you are new to flashing, you might want to go with milestone 2 for a few days and see how it feels. On the other hand, you could jump in balls deep and go with the latest nightly/experimental
And you don't need to wipe anything before flashing the extras package.

doesn't matter,
infact if you flash yakju then you will get OTA as well. if you are in japan you can flash a japan radio on top of the rom.

Kernal?
I have been researching the many different kernels out there all day. I have been running GummyNex ROM's since I rooted my GNex. I really do like the options he has. I forget which version, but the battery life was amazing (which included the baked in kernel). I flashed to .0.9 and recently 4.0.4 1.0.1 and the battery life is like a V-12 Lamborghini. I just flashed a Franco Kernal and am hoping this fixes my battery drain issues.
Something has to give......

Use liquid rom with Franco milestone built ... gave me a 4+ hour screen time. Don't know why but the nightly version reduces battery life
Sent from my Galaxy Nexus using XDA
I'm running Liquid 1.3 and am using Franco nightly #143 and, so far, my battery life is really great. I was at 89% after 2 hours. I also want to try Milestone 3, that just came out yesterday and see how it performs.

[Q] franco.kernel vs stock 3.0.8

What are the differences?
I'm using Android Revolution HD 3.0.0 now and in the description mike1986 claims that stock 3.0.8 kernel is the best so far but with so many people using franco's kernel it must be better or am i wrong?
Also, will flashing franco.kernel on Android Revolution cause any bugs etc? (I'm kinda new to this whole flashing kernels part)
(If there are better roms do not hesitate to recommend me one and please tell me what's better if thats the case )
Thanks in advance!

I can not list the differences for you exactly just go to franco's thread. There are many advantages to flashing a custom kernel. The kernel devs work hard to make the kernel's better than stock in many ways. You'll get extra features and extended battery life for sure out of a custom kernel. Stock better? I dont think so! Flashing a kernel after a rom is the way you have to do it but, ya some settings might not work if the kernel dev had done things differently from the rom dev.
give it a shot if you dont like it you can always reflash your rom package to restore the roms kernel.
before flashing a kernel (or reflashing your rom after flashing a custom kernel) wipe your dalvik cache
so many people around here have a boner for franco but I always highly recommend GLaDOS kernel its imo the best and most advance but to each his own

Good Kernel and Rom

Hello dear Community,
i am owning a GN and i Rooted it about 2 weeks ago.
So now my problem is i tryed some Roms and Kernels.
But i wasnt happy with theese.
To much bugs or to fast Battery drain. And instable.
So my question is which Kernel and Roms are good?
I prefer:
Good - High Battery perfomance
Stable.
Can have a good design.
And a lot Functionality.
My GN is GSM. With Maguro.
Im Actually using PARANOIDANDROID.
Sry for my english, thats scool english
Ant thanks a lot for all replies
PARANOIDANDROID is a good ROM but a little Alpha imho. I recommend the following in order of quality and support. I'll recommend Franco nightly kernel with either LiquidSmooth 1.35 or FoxHound 0.6. I'd recommend BAMF but if you go to their thread for support, they got some real douches in there.
Well thank u for ur reply.
I am not a pro but a newbie at flashing roms and kernels.
But i wanna try ur Variation.
Can u explain me how to Install them?
thanks a lot

Me too.
Liquid 1.35 and Franco kernel gives great battery life and pretty good options and stability
AOKP milestone 5 & Franco gives options and stability, though the battery life does not match liquid.
To flash these ROMS, go to their threads and download rom and latest gapps(pls check if reqd or included in rom) onto phone.
Reboot into recovery
Take a complete back up
Factory reset
Wipe cache
Wipe dalvik
Flash new rom
Flash gapps if reqd
Reboot phone
Sign into google
Reboot phone
Wait a few mins
Reboot into recovery (if flashing kernel)
Wipe dalvik
Wipe cache
Flash custom kernel
Reboot phone
If using Franco then download the Franco paid app to get the best from the kernel.

Nightlies are the beta version of the kernel updated for testing on a regular basis. Always download the latest one. In that u have 512 gpu (overclocked) & 384 gpu. Try 512 first if it works for you without any issues (try with a game) then great, else flash the 384 version which is more stable.
If you want complete stability then go for milestone 3.

Paranoid android kernel and adding diff kernels

Hey guys, running paranoid 2.53 on my Verizon nexus. I have read all the stories before getting the phone that batt life is not great. Agreed. So I wanted to play around as I have never changed kernels before.
One thing I was wondering is what type of kernel is included in this ROM. Another thing is I got the Franco kernel updater. I have been reading for days on xda and such what a kernel does, how, why and such but I haven't found any answers regarding Franco or lean kernel w pa 2.53. Can I just DL and flash right from the app or is there a process to get a new kernel and which do u guys prefer. I want battery life over perf but I don't want a sluggish phone. Is there also a way to backup my stock kernel other than a complete nandroid. Would I backup boot and the system image. Im using twrp 2321
Thanks for any Advice and thoughts
