1-root with cf-root for you firmware using Odin.
2-boot into recovery and do a cwm backup or use the cwm app that installs with cf root to do the same.
3-if you want to go back to stock flash the original kernal using Odin and use a download mode jig to reset counter to hide flashing.
4-if you use a custom rom restore backup then do the above step.
You can find plenty of how-to's on any if the above points on this forum or by Googling it.

Ok. To flash the original kernal you will need to get it from the intratech thread. He had them all I think. This will remove the custom kernal and, assuming you are still on stock firmware everything is stock again.
As for the jig, when you flash a non stock kernal, there is a counter which shows when you go into download mode. Samsung put this in to see if you had flashed anything if you return it for warranty. The jig plugs into the phones USB/charging port and clears it so Samsung knows ****. I bought one off eBay for $2 delivered.

[Q] Does rooting require exact same kernal? Galaxy s2

I am new to the android .and bought my first galaxy s2. I will follow the s2 one click root to root my phone. I need to know if I need the same kernal as my device? My original kernal is JPKG5. do I need jpkg5 insecure kernal and then a jpkg5 secure kernal to root my phone? Or can I change my kernal to some other kernal of my choice?
my galaxy s2 gets pretty hot if I play intense games like asphalt or star legends, it even gets hot if I use mobile internet like EDGE (i guess its 2g internet nott sure) and browse the internet. The battery life sucks. I keep wifi, gps off and it last like 7 hours if I use mobile internet. Heard a different kernal might help.
One last question, what is the purpose of titanium backup? Do I get to restore my phones original self back again easily? Like will it unroot itself and return to the original gingerbread rom if I decide to change to cynogenmod? If titanium backup does not do that, then how can I unroot my phone and then get back to my original gingerbread rom?
Thanks alot for your help...

Welcome to Android I am not sure about the kernel. The purpose of TB is that you can backup all your apps and data and if you flash a new custom rom you can use TB to restore all the apps and data. Its a very powerful application. You can always flash the original stock rom downloaded from Intratechs thread http://forum.xda-developers.com/showthread.php?t=1075278. Then you will have an unrooted phone. Beware of the custom counter!!

If you are international S2 (i9100) user use CF-Root instead SOC:
http://forum.xda-developers.com/showthread.php?t=1103399
Dont use CF-Root or SOC if you are AT&T user, there is specific threads on how to root AT&T devices.
CF-Root is 1 step only, this means for a non experienced user like you (as it's your first android device) less chance to screw up something.
Follow carefully the instructions.
Be sure Kies installed but NOT running (kill kies process) because kies block odin = semi bricked phone.
Takes about 30 seconds

im a bit confused, all those stock kernals in that link u gave are kernels and rom? Like if I have cynogenmod rom installed in my fone and then flash my phone again using one of those stock kernels/roms, I would be flashing back from cynogenmod to gingerbread 2.3.3 (JPKG5)?
Also what is the custom counter?

sorry for the multi reply post, dont know how to quote 2 messages in one reply...
Cf-root seems like it will limit me to only one kernel, is it a fact? Is it possible for a gs2 user to use any kernel he desires? because I would like to use a better kernel than jpkg5 but stick to the original gingerbread rom 2.3.3. Then mod it to stop loading the so called bloat somehow using an app. Plus I found cf-root to be a little confusing, can u help me understand this? Cf-root will use the kernel inside the phone and leave it intact plus give me root? Or will cf-root change my kernel permanently?
Thanks for all the trouble everyone, if its ok ill ask more questions if I get stuck, but will try my best to figure it out myself first...thanks again...

If you flash one of those ROMs you will flash from cyanogen to your original. The custom counter counts how many times you flash a custom rom / kernel - it can be a problem if you have to send your phone in for repair. Read more about it.

cf-root is an original kernel with root+cwm inserted. No it dosnt lock you to a single kernel, its just the most easy way to root your phone while keeping your stock rom. When you are rooted you then can flash any kernel or custom rom you want.
You only need to pickup the same (ex: kh3, ki4, kf1 etc..) for the root process, this to have full compatibility during root with the stock rom on your phone, but after successfull root you can flash any kernel/rom for the s2

[Q] Help! How to remove CWM from S2

Hi,
I just got my Android and happened to Root it with a firmware containing CWM because I really had no clue as to what it was. Now I would want to be able to remove this icon CWM from my phone. I have tried flashing the kernel to no avail. Please help me with a step by step procedure to remove it since I'm absolutely new to Androids. My S2 runs gingerbread 2.3.6. I did check the web but am so confused with all the options provided.
Thanks in advance.
flash stock rom usin odin simple
It is strongly recommended to back up stock ROM before u give try to Custom ROM.
*#1234# - Check your Firmware version before u do Rooting and make a note some where
You can use those information to download your STOCK ROM from many website (google them)

Since you are rooted, use any file explorer with root access and delete the cwm manager.apk.
Second option is use root un-installer and uninstall the cwm manager

in some Firmwares CWM is included in system applications, so cant simply uninstall it, you can use Titanium backup application to uninstall system apps,
But before uninstalling better you learn more about Rooting and the functions of this app and other root apps. This is a very usefull app in the rooted and Clockwork mod installed devices, for rebooting into recovery easily, kernel flashing, backing up of the Rom ect..
you can have informations from below sticky thread as well as from my signature links.

Thanks guys for your prompt responses. I will try and flash the stock rom and let you know if it work. Thanks again

Will they charge me (even if my device is under warranty) because i have installed CWM?
Do I really need to remove CWM? If yes, how??

Yes you will need to remove root so flash Sam firmware with mobile Odin and don't root. Now back to stock. :thumbup:
Or send it in and report bk

Thanks for replying andrewwright!! (you too "theunderling"!!:angel
I haven't actually installed CWM yet and came here to clear my this doubt.
Why Sam Firmware (if Sam = Samsung) while my device is XOLO q800? Can I take a backup of my my stock firmware in some way because XOLO is not a popular brand and I won't get much support(stock firmware) over internet.
Also, I read somewhere that particular firmware corrosponds to a particular chipset(mine is MT6589), is it true??
I would really appreciate if you can provide a link for reference where I can read further or otherwise some people will keep yelling here "noob......noob"

Restore to stock firmware.

Guys,
I know that theres a lot of topics about this over the forum, but I couldnt find one that is up to date.
Im running the remix rom 1.7 and Id like to restore my phone to factory state.
Could someone direct me to the best way to do this?
Thanks in advance
Sent from my GT-I9100 using XDA
That depends on whether you just want the stock rom to use it or to send it in for repairs.
If you just want a stock rom to use: Just flash a stock firmware with Odin and there you go.
If you need a S2 in its "original state":
1.) Flash an older bootloader and use a USB-Jig (see the USB-Jig thread about that) to set the Custom Rom Counter back (oh I forgot: There's also the possibility to use the "Triangle away"-app instead of a Jig)
2.) Flash a "full" (Pit File, PDA, CSC and Phone) stock firmware with Odin

Go to sammobile.com,
Download a stock ROM closest to that of the OS you want (GB, ICS),
Put file in PDA section of Odin,
Flash ROM,
If your custom binary counter is not zero, buy a USB Jig off eBay for like £2,
Your done.

Search the forum for the answer this is a common problem. You will need Odin. Since you have bricked your phone install a custom Rom and Kernel. You will not go back to stock!!

What firmware was you using when this happened. You've sounds like it's recoverable. If download mode is all you can get your probably get best results by downloading official firmware from Sam firmware and extracting it then flashing the zip file in odin via PDA section. All the best.

I don't remember exactly my firmware but it was 4.0.3 and I haven't installed 4.0.4 but I did have CM10 just before I did restore from CWM and now I did factory data reset, this happened.

Flash a stock Rom via Odin. Wait till your phone boots up. Go back to Odin install a custom kernel (i recommend siyah kernel). Backup your stock Rom, then install a custom Rom. There is a lot of tutorials to tell you exactly how to do this process. If you need help at any point of this process just send me a message and I will give you a detailed walkthrough. You should be fine though!!
Goodluck

How about from the intratech's thread? And is the Odin flash failing risk big with the situation I have right now?
I've used odin A LOT and never had a problem. I only ever use the PDA section and never touch anything else because I don't understand it. I can't comment on intratechs thread as I've never used his software. Any custom ROMs are normally flashed via CWM.

This is because you flashed a wrong kernel for your phone.
# Quick question:
Is your phone on Gingerbread, Android 2.3.x or ICS (Ice Cream Sandwich), Android 4.0.x?
# If your phone is on ICS, then download and flash this kernel via Odin: www.gokhanmoral.com/public/files/siyahkernel/v3.0/Siyah-v3.5.2.tar

# If your phone is on Gingerbread, then download and flash this kernel via Odin: gokhanmoral.desean.net/siyahkernel/v2.6/Siyah-v2.6.14.tar

Thanks for that.
I have the I9100BVLPH stock ROM from T-Mobile UK on my phone so I downloaded the correct Chain Fire kernel (CF-Root-SGS2_XX_OXA_LPH-v5.2-CWM5.tar) from http://forum.xda-developers.com/showthread.php?t=1103399 and this caused the phone not to boot.
Thanks for the link to Siyah, I used the v4.1.5 kernel and it worked great.
Hello there.
I'm in a bit of a trouble so I need some help. I've bought an S2 for my wife from a guy (in Ireland).
The phone was locked on Vodafone so I tried to root it maybe I'll be lucky to unlock it with out paying nothing. So, the phone is on Gingerbread with a BUKJ3 kernel. I've downloaded last night a CF root but by mistake I took a KG3 instead of KJ3. After flashing with Odin 1.85 I got stuck on the boot screen with the yellow triangle.
This morning I've downloaded another kernel as in KJ3 flashed with Odin, the phone is starting but no network coverage, I tried with different Sim cards but nothing so I went in recovery mode and wipe/format data, system, dalvik and cache as factory reset as well. Since that moment the phone won't boot, it gets stuck on the boot screen and yellow triangle.
I can go in recovery mode and download mode with no problem but I can't make it start.
I reflashed the kernel, I don't know what to do and tomorrow is my wife's birthday and I was trying to surprise her with a nice phone but instead looks like she is gonna get a brick ( I hope not)
Thank you guys for any help.
Go to sammobile and get something like unbranded XWLP7 stock rom....flash via odin
Then use rachmats ics rooting guide
Backup efs folder and make nand backup
Then get unlock app(by helroz or chainfire)

Thank you for the reply. I don't mean any disrespect but for the last 3 hours I'm looking over kernels and forum and my brain is really wired now maybe.
I've had a look at sammobile but I can't find what you've recommended. A more specific link will be more than helpful.
Thank you very much anyway. If I'm getting advises it means I didn't bricked the phone so I might be able to fix it.
Once again thank you.
You just go to sammobile,then register,then firmware and files,then put the info in the 4 fields
eg
Smartphone
Android
Gt-i9100
Then uk/ire XEU (or vodafone or whatever..but unbranded better)
Then youll see a list about firmware version and their release date
Eg
Lpt 4.0.4 ics jul 2012
Lp7 4.0.3 ics apr 2012
So download lp7 4.0.3 and flash with odin.
Then use the rooting guide in my sig
Then do the other things I said.

Thank you very much. In the mean while I've managed to find exactly what you've said in your answer. I've choose the gingerbread version of the ROM cause that was what the phone had when I've bought it.
SO, now is it safe to go on ICS like I did half an hour ago with that Gingerbread rom?
Thank you and sorry about the noob question, never used an Samsung, only HTC.
Yeah just do what I said.......not what you think!.

Did it, thank you very much. The phone start but somehow I've lost my IMEI number and base band. I must be really unlucky.
I've read that Odia can help in this matter but if anybody has any idea, I'll be happy to make a donation for getting back the IMEI number.
Once again thank you very much.

It's always about read read more.... And don't flash anything unless you are 100% sure...

People contact Odia when theres a problem with their efs folder/no backup.
But you should have a backup and a nand backup.
I had the same problem yesterday and I restored efs folder/restored nand backup.....which got it back.
So try that or theres a thread about "restore imei in 9 easy steps".

I know I was stupid enough not to read before flashing, but now it too late to think about that.
the thing is I've never used a galaxy phone until these days and I wasn't aware of all this things and I don't know how to restore this NAND backup IF I have one, as I didn't make any backup before flushing. I hope I'll get some help from somebody and as I've said, a nice donation will be on the way to the helper.
Try GSII repair app.But you have to be rooted.
