I rooted my S2 on receipt near release. I am now updating it fully and trying to install a true stock kernel. Whatever kernel I use though, the info about the phone kernel still seems to show that it is modified in some way. For example after a Kies upgrade I still showed [email protected] Likewise after installing XXKE4 of the official kernel thread I am now showing [email protected]
Is there anyway to get a truly clean kernel back on the phone?
[email protected] = Android signature it has nothing to do with rooting .
Flash a stock kernel or stock firmware and its truly clean .

If i reflash the official firmware, upon initial boot up it will show trying to load csc xxx fail than succesfully loaded multi csc something like that..
My question is, will that be a give away that we have played around with rom flashing? Becoz im planning to return my phone which is running custom kernel...just want to make sure everything will go back to stock.
Thanks

Surely this is still going to be a warranty issue though

Hi all,
A quick question on how easy to roll back (un-root) and put back the stock ROM?
My current ROM is stock Telstra ROM. (just bought the phone today)
PDA: DVKF4
PHONE: DVKF2
CSC: TELKF3
Build Info : Jun 21
I know how to roll back a HTC Desire - by installing the RUU image from HTC or use the PB99IMG.zip install method to remove "root" and put back into std ROM.
I have yet to root my SGS2. Reason to un-root and go back to stock ROM is for warranty purposes. you never know what will happen (for example, my desire decides to dies on me yesterday, had to put back stock ROM to submit for warranty claim).
thank you in advance

Very easy basics are install stock rom removes root and use usb jig to clear custom rom counter .

if i do not install any custom rom, therefore, the usb jig is not required, right?

Nope. Jig is only required to clear the custom Rom counter, in case you have to claim warranty and return the phone to Samsung. And also to force the phone in Download mode, if something bad happens while flashing custom ROM etc.
hey cad,
Made any headway here?
I just bought an SGS2 from Telstra as well and I have a similar phone to yours.
PDA: DVKF4
PHONE: DVKF2
CSC: TELKF3
I too would like to retain the stock kernel, firmware and csc.
If we root with an insecure kernel, how do we go back to stock kernel if it's not downloadable?
Could we just flash another kernel if we are making a warranty claim and hope they don't check?
I assume CSC is where all the Telstra crap is stored and once we get ROOT, we should be able to back this up out of \system

Usual is flash a relevant stock rom or older stock rom and update via Kies.

Hi all I new to all this so could someone point me in the right direction...
1. I need a noob friendly guide to explain what rooting is.
2. How to root.
3 what is odin and all the tools required to root and flash custom firmware.
Video tutorials would be healpful. Im comming from a HTC HD2 but it feels like the explanations were easier to find.
Thanks in advance.

Pity my official firmware is not listed

(please excuse any typographical errors)
Guys,
Recently ditched my Desire HD which I've had alot of fun with for (what I considered to be) a far superior phone but basically got a little fed up with the display after catching a glimps of the SGS2's screen, haven't had the HD on since!
Although I considered myself adapt at flashing and rooting, I have to admit to finding myself a little confused here as to what exactly I can do with my phone. Yep, I've searched, nope, I don't want flamed, just need a few things cleared up then I'm off to have some fun!
Details from my phone...
PDA: I9100XWKF3
PHONE: I9100XXKH3
CSC: I9100CPWKD1
I'm rooted using CF matched Kernel and have remained on that, does no harm as far as i'm aware except for yellow triangle at boot..
I'd like to go from 2.3.3 to 2.3.4 too and wondering about what to flash and what would fit, my CSC is Carphone Warehouse would that be correct? How important is it to match CSC?
Regards Baseband, doesn't really matter does it but no harm in trying modems is there?
And firmware, thought about Frankenstein XXKF3 or 4 or am I getting things totally wrong? Think it's the WK to XX and not sure what impact that'll have.
And on that note, does the firmware version stiplulate which ROM I can load? So if i go to 2.3.4 (XXKH3 or 4) am I then limited to flashing only XXKH3 or 4 ROM's? Does it matter what I flash over my phone? I've also read that some ROM's contain Kernels and may have to flash a stock kernel after flashing the ROM to match firmware or even re-root?
Actually the more I read back on that, appears I know nothing at all and that's not even funny! Even went back to the original SGS forums in the hope that I'd find what I need there.
I know that unless I move back to stock (which I am at the moment), Kies wont off the eventual 2.3.4 update but to be honest I'm not fussed as developers and cooks here do a much better job and that's experience from my HD days.
I have flashed MIUI as that's the ROM I used longest on the HD, loved it but quickly went back the more I satrted to read and to be honest, would prefer to stay stock for a while and get used to the phone, is that do-able with a flash from the developers forum?
So does the ROM have to match the firmware I'm currently using, can I upgrade to 2.3.4 firmware, choose a kernel of my choice and any rom?
Obviously not picking something up, hopefully someone has the answer I need without the links to pages read allready, want to start having some fun and soon!
Cheers!

firmware is read by the last three letters KF3 is what you currently have.
there is no problem upgrading to KH4.

no your not limited to flashing any rom, you can mix and match arounding to your needs and preferences.
after rooting they reflash the kernal to get rid of the yellow triangle, there is a tuturial for that chainfire's rooting thread, 2nd post.
So does the ROM have to match the firmware I'm currently using, can I upgrade to 2.3.4 firmware, choose a kernel of my choice and any rom?

no the rom does not match the firmware, yes you can upgrade to 2.3.4.
yes you choose the kernal and rom that you prefer.
All roms contain a kernel .
CSC is not really required as long as you enter the settings for your network manually but stick to cwm or xeu for UK ..
CSC are not upgraded and are often much older than the rom version .
KH3 probably the best current modem .
Rom is the whole firmware kernel modem OS etc .
You can have a KF2 firmware and swap kernel to KH2 and modem to KG2 in theory and it will work most of the time for varying combinations .
USB jif is better than flashing kernel to remove warning triangle as it also resets rom counter to zero
Me >>Cognition 1.51 rom based on KH3 and i have KG2 modem and no CSC .
Kernels have swapped just the kernel about four times on this and swapped and tried every rom on here .
Rom backed up using Nandroid via CWM recovery and apps backed up using Titanium pro .
Even a failed boot is usually recoverable with ease on SGS2 .

Hi,
I want to install cognition s2 rom on my galaxy s2 but first I wanted to know how can I go back to the stock rom if I happen to dislike the custom rom? I searched but couldn't find a concrete answer.
Thanks
Standard Method is flash a stock rom .
Reset custom rom counter to zero with usb recovery jig .
Stock Roms .and csc

Ok so maybe you can explain to me what's the difference between a rom and a kernel/firmware? Because I only see kernels on the page you sent me =)
Also, does it matter which phone/modem, csc I flash? If so how does it affects my phone?

a kernel is what directly interacts with the hardware. Every OS has this, but it's more customizable on our phones since it's based on Linux. The Rom contains the OS itself, and the software and file structure therein. The kernel even can tell the OS how fast the processor goes and how much juice to use from the battery.
from the link that JJEgan gave you, u just pick the one you want and flash with odin...thats all you need to do

Ok get it but lets say I want to upgrade to 2.3.5, I understand that I have to flash the KI3 rom right? But do I need to flash the whole package (pda, phone/modem and csc) or just the kernel intratech posted?
lol sorry but I'm a total newb on android

A kernel is not the firmware
so flash as instructed with whatever 2.3.5 upgrade you are using .
jje
if you want 2.3.5 then you have to flash the whole package, just download one of the files from that site and flash in odin under the PDA bit
Well I've googled quite a few key words to see if I could get the answers to my questions and I haven't found too much yet. I have a Bell Galaxy SII that's rooted 2.3.3 Android version. I ended up flashing my kernel long ago as well which gives me the yellow triangle now I don't care about that but i want to make my phone like it was when it came out of the box. I have the original firmware and kernel. What im confused about is there is Odin to flash this and that and then there's dumping the files on your phone and using Clockwordmod. what's the difference? which should I use and what do I flash first? the original Kernel then firmware? or other way around? or does it matter? youtube is nice and all but it shows customs unroots for branded S2's not mine which is Bell im having issues with my tethering disconnecting me from my computer so I think it's best if I revert back to factory since all I do is make phone calls and tether. Thanks guys

No as you have just flashed an original kernel .
Reset custom rom counter with USB Jig .

the moment you flash a stock rom it will contain the stock kernel so you would lose root and all the custom stuff you had, basically what you have is an out of the box device

perfect thanks im just messing around right now with going back stock to see if that fixes my issue with getting Disconnected when I tether now I wrote all this info down so I can go back and forth over time and experiment with different roms
most of the custom roms do not support tether which sucks, but yeah its part of the fun to flash stuff over and over
agreed with above posters, flash it over and over again until you fully understand how the flashing really work
my sgs2 download counter has reach 16 because I was affraid to use cwm flash, so i went back and forth from original rom to custom rom
Hey Guys!
I just bought the mighty S2 and am loving it.
Baseband version: I9100DDLPA
Build Number: IML74K.XWLP7
I tried rooting my phone with ODIN and CF_ROOT method. This is the file version i used.
CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5.zip
Now after rooting, my phone booted automatically. When i tried restarting, it was getting stuck on the yellow triangle.
I then downloaded the other kernel and tried flashing that too with ODIN.
CF-Root-SGS2_DX_XTC_LP7-v5.4-CWM5.zip
But alas..
Then i downloaded the official ROM for my country and flashed it with ODIN. Fixed my phone. Below is the firmware i used.
GT-I9100_INU_I9100XWLP7_I9100ODDLP9_I9100DDLPA
This runs on ICS 4.0.3. I see that there's one more ROM of my country thats 4.0.4 on samsung-updates.
So my questions are as below
1) Which CF_ROOT version do i use to get my stock firmware rooted?
2) Is 4.0.4 any better than 4.0.3? Where do i find the changelog?
3) Can I flash a firmware of ANY country? Does it matter if I flash the firmware of my neighboring country?
4) Where do i find the stock kernel for my Firmware?
5) Does flashing the official firmware flash the stock kernel along with it? Meaning will it remove the Siyah-s2-v4.1.5 i am currently running :cyclops: ?
6) If 5 is yes, and if i need to by chance send my phone to the service center for warranty, and also if I am running a custom rom, will flashing the original firmware of my country + removing the yellow triangle + resetting the counter bring it back to warranty? ;P
7) Is there a way to try a ROM from the SD card without actually flashing it?
I seriously gotta parcel a crate of beer for the one who answers my questions.. One all set, I am in for trying out a custom ROM!

1 I don't know I use siyah kernel to root although there are full instructions in chainfires thread.
2 4.0.4 is better than 4.0.3 as it's an upgrade , use Google for change log.
3 yes you can flash any countries rom for your device.
4 in Stock rom. Just reflash the ROM to stock kernel, but this will loose root access.
5 yes. Correct.
6. It will remove triangle but you need triangle away app to reset counter. Credits to chainfire
7 no not that I know of.
Sir can I suggest you read the sticky threads in this forum. There are many excellent guides, advice, tips and information. You would do well to read them to save bricking your new device.

Hi Handsy. I am doing that. Thats were i learnt how to root n stuff but it failed. Hence used Siyah kernel and automagically got Root access
Anyway regarding point number 4, i didnt understand what you meant. DO I reflash the entire 350MB firmware just to get the stock kernel??

Yes to get stock kernel re-flash the whole stock rom. There is a method of extracting the kernel from the zip file but I've never tried it. Easy and safe to re flash whole rom package.

I noticed that flashing the firmware didnt make a single change to my phone. The apps and settings were totally intact. Will installing 4.0.4 too be the same? Also i heard about this brick bug on our phone. Does that happen while only wiping data/cahche using CWM? Is there an anther way of wiping data/cache/dalvik etc? other than factory reset for the bug

When moving between like firmwares (same number) you often do this without wiping data however when upgrading or down grading a full wipe is necessary. To avoid brick bug only wipe with a custom kernel eg siyah etc
