Can anyone please get me the "virgin" UCKK6 kernel designation/name using CPU Spy? I am looking for someone with a phone that has never been rooted and has never changed the stock ROM. I have rooted and changed ROM's myself and am trying to get it back to a like new state and want to see if the kernel version I have matches a "virgin" phone.
Thanks!

Virgin zImages are in my Return-to-Stock thread in Development.
Thanks. That's what I used to restore my phone. I was just double checking the kernel designation after it had been updated to UCKK6, as I believe your return to stock uses UCKH7. I'm kind of anal that way.
By the way, you rock! I appreciate all the time and effort you put in here. I have spent way too many hours reading your posts.
The one you want will include the following essential info:

Afternoon all,
First of all I would like to point out I am a complete Android noob I make no secrets about it, have been a iPhone user for a few years with Blackberrys prior to that, so everything is new to me.
I decided to opt for the SGS2 for my newest phone upgrade and after a week or so of use the battery was terrible (holding only 6-7h max). I read through endless threads on rooting/custom ROMs and the likes and decided to try VillianROM 1.4, to help improve the battery.
Managed to sucsessfully install it with no major dramas.
However, I think I may have the wrong CFroot kernal installed. After installing the villianrom, one of the last parts is to update the root kernal, it stated to use XWKF2. mine currently states:
Baseband version - I9100XXKF2
Kernal Version - 2.6.35.7-I9100XWKE7-CL215725
Is this correct?? If not can someone point me in the direction where to download the correct kernal.
The phone is working fine at the moment and the battery is vastly better compared to how it was. I have noticed a problem with the music player, it seems to crash mid way through songs and re-boot, has anyone else had this issue? or could it be as a result of the incorrect kernal?
Thanks in advance,
Shakey
p.s - loving my Android experience so far and dont think ill be going back to Apple any time soon
I would leave well enough alone if its working .
However the VR rom instructions say .
If you are installing from another ROM, or stock ROM, you need to be using the CF-Root kernel, as applicable for your current ROM. You can find CF-Root and
instructions at http://forum.xda-developers.com/show....php?t=1103399
When using this ROM, I suggest the XWKF2 CF-Root kernel, from post 4 of Chainfire's thread.

Thanks for the quick reply jje.
It does seem to be working fine, apart from the music player issue, ill put XWKF2 on and see if that fixes the issue.

I just want to root my S2 but don't want to encounter any glitches and issues that some people seem to be having with these different Kernels. My stock Kernel is UGKG2.
Bell Canada Galaxy S2 Released July 21st 2011
Model Number GT-I9100M
Android Version 2.3.3
Baseband I9100MUGkG2
Kernel version [email protected] #2
Build Number GINGERBREAD.UGKG2
Unlocked from Bell and using on Rogers.
It seems the 3 different KG2 Kernels that are currently available are:
CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip
CF-Root-SGS2_JP_XSG_KG2-v4.1-CWM4.zip
CF-Root-SGS2_XX_OXA_KG2-v4.1-CWM4.zip
What one should I use? I don't want to experience network issues or any weird glitches. Will there be a stock UGKG2 coming out in the near future that I should just wait for?
Am I even asking the right question? Please excuse my newbiness. I've been reading through hundreds of posts and it's just making me more confused. I've tried SuperOneClick but it hangs at Step 5.
I'm not sure I understand this whole rooting thing. From what I gather, to root you have to use a different Kernel. And it's that Kernel that is giving you root privilege? Yet I see people saying something about CF Root. I think I'm way off somewhere...
Thanks.
Ok, let me start this off by explaining something.....
The rom letter versions are actually based upon 5 letters, not 3. There are several variants of KG2. Basically, the Samsung naming convention is as follows:
Model name: I9100M
Provider/Area: UG (Bell/Virgin/Sasktel)
Rom Version: KG2
Now, the rom version can get broken down into each letter as well...
K = 2011
G = July
2 = 2nd version that month.
All area's roms are developed completely separate from each other...
Ours is UGKG2. Which is unavailable for download from the Samsung servers, so we're not able to actually get back to stock, or make any kind of custom firmwares/kernels based upon it.
All the other ones, including ZS, JP, and XX are completely different roms and kernels than what we have on our Bell phones.
The KG2 that either of those 3 kernels are based on are either 2.3.4 roms or different 2.3.3 roms. So, matching that is no different than installing a KG1 or KG3 or any KF* CF-Root kernels. ChainFire has not made a CF-Root based upon UGKG2 yet, so no matter what one you install, it's not based upon our rom, meaning you can basically install ANY CF-Root Kernel and as long as your phone still works with it, it doesn't matter. All the roms are completely different and the naming convention has nothing to do with each other unless all 5 letters/numbers match up.
Personally, I'm waiting for our stock rom to be released for warranty return purposes before I flash one of the root kernels.
However, if you're willing to take the chance, I suggest installing a 2.3.3 kernel as that's the UGKG2 Android version.

Thank you Electroz.
I'll wait and keep an eye out for ChainFire to come out with a stock one for us then!
Another thing that confuses me is this:
People are talking about using one of the Kernels to root and then reverting back to their backed up Kernel while still maintaining root? Is that possible?
ie.
I pick a 2.3.3 KG2 Kernel, root and then use a backup of my UGKG2 again? Then all is good? And I'm rooted? Probably not eh?
That works in theory. However there is no way to root without flashing over our stock kernel. So until our firmware is available on the Samsung servers, we cannot go back to the stock UGKG2 kernel if we overwrite it with a "root" kernel.

I'm so glad I found this thread. My SII is my first Android device and I was looking on rooting it but I'd rather wait for a way to revert back to stock kernel before I do so. Can others who have rooted their phones please tell what kernel they have used?
Flash CWM kernel and root using SuperOneClick, or flash Dark Core 1.4. That's what I used on mine. Downside is the original kernel hasn't popped up in the net yet, so there's no going back til it does.
If you need to get rid of the yellow triangle you'll need to use the download mode jig to wipe the flash history.

If you can live with the yellow triangle (or can jump through a few hoops to remove it) then just flash one of the custom kernels. I'm using Niphetamine and it's been spot-on.
I just registered on this site to freaking thank you Electroz.
Your post answered pretty much all of my questions.
Wow. So did I! I'd like to add one question though. What brought me here is that I have HORRIBLE Battery life with my SG2. Had it for 1 week, and I'm usually down to 40% by lunch time. And that's with what I'd consider light to moderate use. There's definetly something wrong, and I was thinking that it was the firmware version that I had.
Probably wrong thread for battery life question, but it is somewhat related to the firmware... so can it be that, or could I have a defective battery?
I also have a Bell SGS2 with Kernel UGKG2.
Loaded an insecure Kernel and I rooted it.
Unlocked it with Galaxy S unlock app. (The Galaxy S2 unlock app didn't find the code)
Used it for 2 days on Fido's network with the insecure kernel. Battery life was horrible. It'd be completely drained by 4-5pm. (about 8-10 minutes calls, about 30 minutes internet, about 30 txt messages) Yellow triangle was there.
I also couldn't use Kies from PC. It wouldn't recognize my phone.
So, I re-flashed with stock XXKG2 kernel since ours (UGKG2) is no where to be found. I know it's not the same, but at least, it's the same build. Insecure kernel is an old build (with all those problems that are now corrected with more recent builds).
After flashing with XXKG2...Triangle gone.
Battery life is greatly improved from insecure kernel. Same usage, still have about 15-20% when it's time to sleep and recharge.
I can also connect to Kies on PC now.
I think it's the best solution for now for the people like me who absolutely need root to unlock asap.
I'll flash the stock UGKG2 once it's out.
EDIT:
By the way, re-flashing to a stock kernel after rooting (in my case XXKG2) doesn't remove root.
Just flashed my buddy's i9100m with CF-Root XXUG2 kernel and it booted with a yellow triangle in boot screen, and went into the system
I guess it worked as I can see SU on it.
thats a great explanation on the first post thanks alot, i was wondering if anyone here could make a backup with clockworkmod from a rooted galaxy s2 that still has the UGKG2 on it and post it so i could get access to the baseband file and use it as a restore, that would be very appreciated!!!
im getting the worst reception, cant even send text messages outdoors!
and forget about data.... all i can use is wifi

could u or your friend post a backup so that i can restore from it?
I have also flashed my phone with XXKG2 Kernal, and so far so good. I am also using Canada's version of the phone. I wished that I would have read the forums better before I did as I failed to make a backup. Seeing as this is my first Andriod phone I didnt know any better. With the exception of some GPS lock issues everything has been great.
Keep up the good work XDA devs, you guys rock! I have really learned alot creeping these forums the past few days.
Thanks from Canada,

Confused...
I'm not a n00b but also can't call myself a pro, but I was hoping that since it's related to this thread in theory, I could get a heads up or something.
I haven't been able to figure out how to update my S2 at all, following stock build and no hacks at all on my phone and it is not rooted.
M#: GT-I9100M

I don't know about on the SGS2 yet as I just bought the phone about 2 hours ago. But I just came from the SGS Captivate, and I had these same kind of issues with battery on CM7.1 custom ROM.
I found that flashing a new modem greatly improved my battery life, I went from being completely dead by about supper time (with light-moderate usage), to over a full day usage.
On that note though with the custom ROMS they are missing drivers to turn apps off supposedly so I don't know if that will come into play, but it would be something to look into if the issue still persists.
Since I can't post in the main thread in the development section, I wanted to make sure I have the right kernel for the CF-Root process after reading the post I've quoted at the bottom of this post.
My phone is on Android 2.3.4 and XWKI4.
The latest rooting kernel that I seem to be able to get from the CF-Root thread is: CF-Root-SGS2_XW_NEE_KI4-42-v4.2-CWM4.zip
That seems to have CWM4 in it so I'm worried that I'll have the same problem as the poster below, (since he is also on KI4)?
Thanks in advance.

Reply (lt_ler):
As I do not trust your signature, please post your current ROM and kernel versions.
Then it is a lot easier to recommend a corresponding CF-Root kernel which will root your phone.
you have the correct cfroot for the version you have posted..
other poster did not read or know what he was doing.
IV4.4.KI4tar does not exist.
Honestly, pretty much any of the CF-Root kernel versions will work.
I realize that people like to keep the same kernel as the stock ROM and that this is the philosophy behind it, because I am one of them, but in reality, the kernel version itself doesn't change enough to make any significant difference.
Try it out. Flash any version with any Stock ROM.
Bet they all work. I tried a few (not all) and they all worked fine.
Thanks

Thanks. I'm just getting started on all this, so apologies if I'm being a bit dense
I understood that using the same version (KI4 etc) would be useful in avoiding the "yellow triangle" thing where you have to do some fiddling about re-flashing with the same version ID. I could probably just about manage to recover from a situation like that, but I'd rather not take any more risks than I have to (being a noob at this).
Since Cosmic Blue has confirmed that I have the right kernel, I'll use that and keep fingers crossed. One day when I get better at this I may be more adventurous!
Thanks to both of you for the help
hello,
my sgs2 is still "untouched" - I mean it has its factory kernel and is not rooted yet.
but I plan to root it...
but before I do that, I wanted to know, if it is possible to save my original stock kernel (e.g. via odin?) before I flash e.g. a CF-Kernel (by chainfire)? So that I can return to my very own original stock kernel which was delivered by samsung for this device... is this possible?
I know there are some stock-kernels available to download, but I'd rather want to backup my very own and put it back on the device, if I want to return to this kernel (unroot, etc.)
PS: here's a post where I asked accordingly if it's possible to safe my very own stock-rom... I'd appreciate your help concerning this topic also very much!
thank you very much!
Hi,
I just rooted my SGS2 last night and I had the same question as you.
As long as you get a kernel which matches yours or as close as it matches yours it should be fine. I flashed an insecure kernel because I used s2root (which works brilliantly!) and then ran s2root, and then flashed my original kernel back using odin3. The kernel is exactly as it was before I rooted and I still have root permissions. If you don't flash your original kernel back after rooting, you will see a yellow triangle under your boot logo.
Here is the guide to s2root: http://forum.xda-developers.com/showthread.php?t=1125414
And here is the list of unstable and original kernels: http://forum.xda-developers.com/showthread.php?t=1101671
If you can't find your kernel version listed there, try the link provided at the top of that page, and you should find yours (I found mine buried in there, both insecure and original).
To check your kernel version, go to Settings > About phone > (kernel version).
Enjoy rooting!

hi chris,
thank you for your quick response. but my real question was if it is possible to backup my very own stock-kernel which is installed at the moment (from samsung)... I don't want to download a "original" kernel but instead use my own backup - if this is technically possible - which is my question in this thread.
I understand what you mean, I wondered if I could do this too.
I have looked around and found this 'app' which allows you to back up your current kernel, and then you can restore it later on (well that's what I assume it does!)
The only thing is that it is called SGS Kernel Flasher, so I'm not sure if it works on the SGS2. It was posted last year so perhaps there is an updated version?
(www)dotaddictivetipsdotcom/mobile/backup-restore-and-flash-samsung-galaxy-s-kernel-with-sgs-kernel-flasher/ (sorry it won't let me post outside links!)
The only thing is I think you may need root access to perform any type of kernel back-up?
I'm not sure, but I just know that when I re-flashed the kernel that matched my original one back, it was exactly the same, so I can't see how Samsung could tell the difference.
I'm sorry I can't be of more help, I dug around on the internet and it was all to do with flashing new kernels, so perhaps it can't be done?

Hi all,
Ive got the stock version of 4.04 that came installed on my phone, I have rooted to remove all the annoying bloatware.
My current kernel is 3.015-611327-user [email protected] #1 SMP preempt from may 2012.
BaseBand Version I9300XXLEF
I was wondering what kernels are worth updating to, for better performance on the stock rom?
Reason why I want to change the kernel is because a friend just got an S3 and his phone seems a little more responsive (hes running all stock and stock kernel).
Any advice or suggestions are appreciated

download all the available kernels
flash each one . run it for a full day or
discharge cycle and compare it for yourself.
things to thjunk about
battery life
performance benchmarks are fun but more look at things like browsing switching apps and so on.
ui lag
remember everyone uses their phone different and want something diff
