Rooting with stock kernel? - AT&T Samsung Galaxy S II SGH-I777

Hello all,
To begin here are the current specs of my At&t Samsung Galaxy S2:
Model Number: SAMSUNG-SGH-I777
Android Version: 2.3.6 (yes, i have done OTA update from 2.3.4)
Baseband Version: I777UCKK6
Kernel version: 2.6.35.7
Build number: GINGERBREAD.UCKK6
So now onto the reason for this post, I have spent several hours...several months uptil now trying to fully understand the rooting process for the At&t Samsung Galaxy S2 and I have a few questions around the entire process that i would like to get some concrete input on.
My objective behind rooting is only to get SuperUser access and be able to remove all of the at&t/samsung apps i dont need or use, and to use apps like titanium backup to backup all my stuff...i dont plan to ever install anything custom on my sgs2 as the stock rom is sufficient enough for what i do on the phone (at the moment).
with that said:
1) is it possible to keep everything stock and just but just enable the SuperUser access, if so, can some1 point me in the direction of what all i need to achieve this?
2) (if #1 is achieved and ) if i just root the phone by keeping everything stock, is there a posibility that my flash counter on sgs2 will get incremented? ( i am aware that there is a method to undo/reset the flash counter back to 0 ("NO"), but i would like to avoid incrementing it to begin with).
thanks for your input!

Hit my return to stock thread - includes a prerooted system image with stock kernel for UCKK6.
Prerooted system images don't trigger the custom binary count.

thanks, i have studied ur post in detail actually, and then for some odd reason, i drifted off onto other threads where i got a bit concerned about the binary flash counter...
Edit: re-visiting your post, i know that it was the thread by creepyncrawly that got me in the concerned stage

[Q] Safest and easiest way to root?

Apologies in advance I am new so some of these questions may be retarded:
First of all I am using:
Samsung Galaxy S2 GT-I9100
Android Version 2.3.3
GINGERBREAD.XWKE7
I would like to root my device to use Chainfire 3D (to play THD games) and other ROMS
What would be the easiest and most stable way to root in order to use a variety of roms and upgrades? I am afraid to 'brick' my device and I was reading through chainfire's updated kernel thread: http://forum.xda-developers.com/showthread.php?t=1103399 but got confused with some of the terminologies and the number of files available for download.
The Lite'ning Rom v1.3: http://forum.xda-developers.com/showthread.php?t=1095274 seems simple enough to use and uses XWKE8.
I would also like to know if it’s easy to revert back to stock after the device has been rooted. Is it necessary to keep wiping your device and backing it up when installing new ROMS or reverting back to stock?
I would also be very grateful if someone could explain some terminologies regarding Kernels, Odin, Superoneclick any other general info would be appreciated!

Not sure what how to root KG2 2.3.3

I upgraded my firmware today on my UK T-Mobile SGS2 today, but lost the root I had in the process. I was previously having a really annoying 'lag' that would make the whole phone jerky and unresponsive and that seems to have cleared up after this upgrade. I'm really keen to do the rooting properly this time... as I'm guessing it was a problem of incompatability that cuased the jerkyness problems I was experiencing before.
From the Chainfire rooting thread I see that there isn't a rooted kernel that is for KG2 and Android 2.3.3
CF-Root-SGS2_XX_OXA_KG2-v4.1-CWM4.zip - Is for 2.3.4
These files aren't labeled as being 2.3.3 or 2.3.4 - does anoyone know:
CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip
CF-Root-SGS2_JP_XSG_KG2-v4.1-CWM4.zip
If you were in my position, what would you root with?
My current phone details are:
Modellnummer:
GT-I9100
Android-Version:
2.3.3
Basisbandversion:
I9100BOKG1

If you are going to root then flash a custom Rom, then I wouldn't worry as the Rom will be based on 2.3.4 probably.
If you want to stay stock, then you could follow my route, CF-Root then flash VillainRom which is based on 2.3.4 and as close to stock as possible with a few tweaks to improve things such as battery life.
Hope this helps
Ideally I'l like to be able to get future official updates through Keis - and I would lose that if I switched to Villain rom right?
I also wondering if I'm going to flash a custom ROM, might I as well flash a more recent Samsung one like KH3? Looking at Villainrom it says there are problems with the stock browser and stock SMS.
Piecing together info from other threads I saw that someone said that you can flash a rooted kernel and then flash back your original unrooted kernel and it will stay rooted. Is this true? If so, perhaps I could flash a rooted kernel (either a 2.3.4 or a 2.3.3 for KG1 or KG3 (close to my rom), and then flash back my current KG2. Thing is, how do I get my current KG2 kernel off the device before I overwrite it with a rooted variant.
Sorry if my questions are a bit basic or confused. I'm still trying to get to grips with all this. Thanks for the patience!
1. Yes you will lose updates through Keis but the custom Roms are based on the most up to date anyway.
2. Don't think you can restore your kernel and keep root afaik busybox etc are baked into the kernel
3. Yes there is a lag problem, it is to do with odexing/deodexing (don't ask me) but there is a flashable fix if you search the thread. Villain Tweaks app should help with the SMS I think.
4. Find your firmware/kernel on Intratechs thread and download it and keep it safe. When you root you will replace the current kernel. If you need to go back then you can flash the original through odin.
Well, since it seems going with a full flash is the only way of rooting with my current officical setup, I'm gonna try KH3 and see how it goes. I'm quite relctant to get into custom romming because I don't normally have the time to deal with the inevitable problems (so I hear), but I do need to be rooted. Wish me luck! and thanks for your help.

[Q] Questions about rooting from a very new Android user

First off, I'm completely new to this and wish to root my new sgs2, and I've done some reading on the forum about this but got some questions (or want to confirm what I think I know) before I actually go ahead with the process. I apologize if it's something others have already asked, but I would really hate for anything to happen to what has become my new baby...
I mainly just want root access on my phone as I've come across several apps and what not that required root access.
My phone's status right now:
Android version: 2.3.3
Baseband: I9100XXKG1
Kernel Version: 2.6.35.7-I9100ZSKG2-CL361136 [email protected] #6
Build: GINGERBREAD.ZSKG2
I found (http://forum.xda-developers.com/showthread.php?t=1103399) about CF-Root. It seems like a lot of people recommend this method to root, so I thought I may try it out. Before I do though, I wanted to know:
- Just rooting my phone will not prevent me from receiving any new updates to my phone via Kies, right? (E.g. a new firmware or version comes out in the future...)
- What do I need to do if I wish to unroot in the future?
- For this method, this should be the one I should download and use right? (it's the closest one I found matching my current kernel): CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip
Again, sorry for asking what may be pretty simple questions, but I really appreciate everyone's help!
Hi,
You can follow this (http://knowmydroid.com/guide/root-samsung-galaxy-s-2) step by step guide to root your SGS2.
1) Yes, rooting your phone means you cannot use KIES anymore. Its highly not recommended
2) Download any official firmware from SamFirmware.com and flash via ODIN
3) You can flash the KH3 version of CF-Root as well.

Hello,
you will still receive updates via KIES.
Unroot is possible with SuperOneclick. I have not tried so far. Every new firmware overwrites root. So if you root with ODIN and flash the rooted Firmware to the original one, KIES will allow to upgrade.
You could also use ODIA's insecure original kernels and use the ones provided from INTRATECH to have the original back on.
Never tried CF myself.
This phone is practically impossible not to root! Read everything thoroughly and take the dive, see you on the other side

Thanks~
Thanks for all the help! I did take the plunge ... and have no regrets!
I used CF's way, and have flashed back to my original stock kernel afterwards (courtesy of INTRATECH). Everything seems to be happy so far.
And now.. time to have some real fun with the phone
Thanks again everyone!
I also recently rooted with the CF-Root method. Congrats from a fellow HK/Taiwan phone user.

[Q] ZSKF4/ZSKI3 Device Root?

Hey all,
I'm a beginner in this rooting society, moving over from jailbreak development on iOS. I am wondering how I would be able to root a Galaxy S2 with model/kernel number ZSKF4 running 2.3.3.
Not sure if this is the proper place to put this, but I've searched everywhere and no place is providing an insecure/original rom for rooting with this kernel number on the file name.
Can somebody help me?
Many thanks,
Nicholas
UPDATE: Anyone know how to root ZSKI2 running on 2.3.5?
Root + CWM .
http://forum.xda-developers.com/showthread.php?t=1103399
Read the post in regard to versions /kernel matching first .
jje
Thank for your reply.
Many guides like the one you gave me, requires kernel matching first, but really, I'm entirely lost in this matching process. Can you give me some heads up on what to choose using my specs I list below?
My Galaxy S II:
Model Number: GT-I9100
Android Version: 2.3.3
Baseband Version: I9100XXKE4
Kernel Version: 2.6.35.7-I9100ZSKF4-CL280225
Build Number: GINGERBREAD.ZSKF4
If you can help me, I will be very grateful.
Thanks a lot!
Nicholas
Instructions in the post are .
Don't worry too much, just find the matching download and use it. What if there is no matching download ? You can ask me to make one, but I can tell you right now, I very very rarely make CF-Root's for kernels on request, unless it is the very latest kernel that has been released by Samsung. In the latter case, be sure to let me know. If there's no match and I'm not making one, try finding the closest match. You should treat "KG1" as a number, but instead of 1-9, we have 1-9, A-Z (where A would be 10, and Z would be 35). "KG2" is really close to "KG1", "KF1" is not close to "KG1" at all.
You want then a KF4 kernel from post 5 .
jje
This one from post 4 should do it: CF-Root-SGS2_ZS_OZS_KF4-v4.0-CWM4.zip
You have a HK/Taiwan phone? If you install Kies you should be able to upgrade to the official ZSKG2. Although that is still 2.3.3 so not much difference there.
Yes, I have a HK/Taiwan phone,
Thanks guys,
So if I have ZSKF4 right now, I'll use "CF-Root-SGS2_ZS_OZS_KF4-v4.0-CWM4.zip"?
If I upgraded to the latest ZSKG2, will there be any difference comparing to ZSKF4? because you said its the same 2.3.3.
Okay, well after looking at the instructions, I got a little freaked out of how long it actually is, and was pretty worried if I do this, I would get a triangle at boot because I'm using Custom Kernel? Also I heard that many people don't want to use CF-Root because there's a higher risk of bricking comparing to SuperOneClick that I used to root my Galaxy Tab 7. So, I checked on something else.
http://forum.xda-developers.com/showthread.php?t=1125414
Thats a one click rooting app for the S2, but what is this "Flashing an Insecure Kernel" and how do I get this kernel for either ZSKF4 or ZSKG2? I prefer the most easiest way so that I wouldn't run into a huge risk of bricking this device. Thanks for all the help on CF-Root above, but would you guys happen to know what exactly is going on in this link?
http://forum.xda-developers.com/showthread.php?t=1101671
That contains all the insecure kernels for the S2 one click rooting application. Which one do I choose if I have ZSKF4 or ZSKG2?
Thank you everyone for helping me,
Nicholas
Rooting with CF-Root is very easy, just start up Odin, click the boxes like it says in the instructions, and it's done in less than a minute. You can use the other method, but if I were you I would just go with CF-Root because 1) so many people have done it and 2) at least you know one person (me) who did it on their HK/Taiwan phone and came out fine (and I was a complete root noob at the time).
I think whether you upgrade to ZSKG2 first depends on why you want to root. If you are rooting so that you can install a custom ROM, then no need to upgrade to ZSKG2. Just root your phone and install the new ROM and you're good to go.
But if you want to keep the Samsung firmware and only rooting so that you can run certain apps or do certain mods, then upgrade to ZSKG2 through Kies first, then root. There is nothing really bad about the Samsung firmware. I run Cognition 1.5.1 + SpeedMod, but it's mostly just for the fun of it. I don't do anything on it that I couldn't do with rooted 2.3.3 Samsung firmware.
And yes, you do get the bright yellow triangle at startup. There are ways to remove it, but I haven't tried. I like the triangle, it's like a little badge of honor for power users.
Yeah, I'm only rooting for just certain apps that require root/superuser requirements. Other than that, I won't put a load of mods on.
So, if I go to Kies, upgrade to ZSKG2, then I begin rooting, would I be using:
CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip
But the thing that scares me is that it says "ZS_OZS_KG2: Untested", does that mean it would be risky to do it?
Hey just noticed in the General forum that the official ZSKI2 is out - and its version 2.3.5 to boot. Check it out: http://forum.xda-developers.com/showthread.php?t=1281717
Yeah the "untested" means the author did not try it personally (can't really expect him to test every kernel from every region). I used it and it worked fine -- that's all I can really say.
Oh wow, that looks pretty cool....
I'm sure I can update to that, which I will, but, does this mean I have to wait for another rooting procedure?
I have a crazy "OCD" that I have to always stay up to date haha. So yeah, if I do this, logically if the CF-Root is able to root it, I will have to wait for a person to make the ZSKI2 kernel insecure version?
Actually, okay, when I upgrade to ZSKI2 kernel, which "CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip" do I use? I don't see a ZSKI2 kernel anywhere...and I'm assuming I can still use CF Root to root at 2.3.5?
You can use a version that is close -- in this case I think XX_OXA_KI3 is the best match. It will probably work with the ZSKI3 firmware -- but I have not tried. (Sorry I mistyped the name in my earlier post, it is ZSKI3 and not ZSKI2.) If you want to be safe then yes you will need to wait until there is a rooted ZSKI3 kernel that you can use.
If you plan to install a custom ROM, then it does not matter what kernel you use for root, since the custom ROM will generally come with its own rooted kernel and it will replace whatever you had before.
For some reason, Kies isn't letting me update.
It says: "This version of this device cannot be updated"
Do you know why this is happening?
By the way, I noticed when I plug in my phone to Kies, I see under CSC, in brackets are (KOR). What does this mean and does it affect any rooting?
UPDATE: I know what KOR means, it means it's a Korean region based device. Is there any difference to what I may be able to update to in Kies or any rooting differences?

[Q]Update from 2.3.5

So, i need to be super careful as this is the wifes phone.
Model number = GT-I9100
Android Version = 2.3.5
Baseband = I9100XXKI3
Kernel version = 2.6.35.7-I9100XXKI3-CL577579
Build number = WanamLite.KI3.V3.0
We bought this phone off local forums a while ago, and it seems to me that it's already hacked to a degree at least. custom rom already?
It's got CWM(v2.0 CF-Root 4.1) on it already which i can boot to through an app on the phone and manually... (ClockworkMod Recovery v4.0.0.2)
It also seems to have superuser installed? (su binary outdated notification, currently 3.1.3) i assume i have root as well?
So question is.. from here.. how do i update to latest version of CWM and android etc WITHOUT stuffing it up and ending my life as i know it?

Download the laatest jb custom rom from Xda which ever android version you want like 4.1.2, 4.2.2, 4.3 and put it in your ext/internal sd card and go to recovery mod and do a full wipe as you are coming from GB and flash your rom.
Don't firget to follow the procedure which was mention on the rom thread which you are going to flash.
Good luck
The phone is currently running a custom rom. You need to ask yourself the question 'Do I want to upgrade to a more recent custom rom (I'm sure there are recent WanamLite builds if that floats your boat), or do I want to upgrade to a recent stock rom & maybe leave the phone rooted ?'.
If you want to upgrade to a custom rom, go to the development sections, read up on some roms & try some out. You should be able to flash these with the CWM version that's currently on the phone; but as always though, read/follow the particular instructions for flashing the rom in question which are always on the first page of the thread devoted to the rom & are always very clear/simple.
If you want to 'upgrade' to a recent stock rom, get one for your country/carrier from Samfirmware, and flash it with Odin (How ? Thread stickied near top of Q&A has instructions). If you then want to re-root the phone (if you flash a stock rom, you'll lose root), again, in that same thread there's instructions on how to do so easily (there are also guides stickied near the top of the General section).
Thanks guys.. just wasn't sure if it was that simple or not
I'd like to update her phone to the newest custom vanilla android rom as possible (not samsung)
will go searching now.. (was looking at NEATROM)
What's this Aroma stuff?
And do i need to update to a newer CWM at all?
EDIT: Ok.. well all done.. seems to be good
It is simple;if everything goes to plan.But anything can go wrong with stuff not working.
Backup your efs folder and make a nand so you can get back to where you started.
Then read the rom thread for install advice and bugs etc.
And Mistahbungle could accomodate your wife if you muck up her phone......lol

ok.. no idea what the efs folder is... but i did do a backup through CWM first anyway..
But everything seems to be ok so far..

You dont need to know what it is,although you can research it if you want.Just backing it up can prove vital if you need it.
A phone is a bit handier if it can make calls......lol
