Hi,
I have stock firmware with root acess and CWM. I plan to do a backup of it and install a custom ROM. Say later I would like to go back to the stock firmware which I have already backed up, will that be a problem? Or do I need to do something special?
Make backup using CWM and you will be able to get back whenever you want. But if you want warranty back, the rom flash counters must be set to zero.
Google "triangle away" program.
As above and any CWM backup requires stock kernel to replaced rooted kernel after.
Simple is use Triangle Away then flash a stock rom.

You can use something like MyBackup pro to backup your apps & stuff, but you won't get an 'image' of your setup like you will with a Nandroid backup done in CWRecovery. Or you could probably use Kies I guess (not sure about how this works though, have never used Kies for anything).
Best way to go would be to install CWM then do your backup before you go making any other changes to your phone (like flashing a custom rom). This will give you a backup of your setup as close as possible to it's original state (tho obviously rooted).
If you want to go back completely to stock (no root), all you'd need to do would be to download your original firmware from somewhere like Sammobile.com (until Intra gets his stock firmware collection up and running again) and flash that in Odin. Or you could get the latest stock firmware available for your phone/carrier/country with Checkfus (PC app, search for it on here/Google) flash the tarball you download in Odin.

Don't think CWM backs up your stock recovery just everything else, to revert back to stock recovery you would just have to flash stock firmware but lose root in the process.

Just as addition to MisthaBungle:
1. Flash a kernel containing CWM recovery (such as CF-Root).
2. Create a Nandroid backup in recovery mode (or use CWM Manager app if available).
If you want or have to restore your stock system, you can restore this Nandroid backup, but you will have to flash the stock kernel afterwards in order to replace the insecure/custom kernel containing the CWM recovery.
Alternatively you can do it like bubba949 described:
Just download and flash the latest officially released stock ROM to your phone, if you want or have to go back to stock.
I recommend to do a Nandroid backup before flashing a new kernel/ROM, just to be sure that you are able to go a step back in case something does not work.
So you will have an additional option ;-)
Thanks all of you for your assistance. I'm doing well with my phone since root.

Hi,
i've just installed the Resurrection remix rom on my phone but unfortunately the banking app that I use a lot doesnt work with it for some reason. How do I go about restoring my phone to the stock ICS and kernel... I do still want to keep root access, though.
This is the kernel I originally flashed it with
CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5.zip
all help will be greatly appreciated
I should add that I tried to restore from the back up that I made in clockwork recovery but the app cant find it so I'm thinking the back up didnt work properly!
Anyone?

Using cwm wipe, if possible, format system partition, after that flash using Odin.
Learn how to use Odin, get file from sammobile, or check fus

you should find everything you need to know in this thread
http://forum.xda-developers.com/showthread.php?t=1075278
Did you make a nandroid backup in CWM? If yes, just boot to recover, do a full wipe and do a restore.
If not, go to receovery, do a full wipe, turn off phone, flash the firmware you want thru odin. Let it boot. Power off again, go into download mode, flash a rooted kernel, let it boot and then flash the original kernel with CWMManager from within the rom.
Thanks guys... all sorted
I'm planning to flash Siyah kernel on my stock firmware (Samsung 4.0.3). In the Siyah thread it says it includes a CWM image. I inspected the Siyah flashable zip and I only found a zImage file. Is the recovery included inside it?
Please confirm that I can return to stock using the method below, im still a noob
* To restore counter I can use TriangleAway app.
* Should I wipe anything before returning from Siyah to stock?
* Then i flash stock firmware through Odin and the counter wont increase since its Samsung firmware right? Does flashing the official firnware also give me the stock recovery?
Is this all that I need to know ?
Should I worry about backing up EFS before flashing the Siyah kernel or perhaps before returning to stock?
Thank you very much! All answers appreciated!

If are on stock ROM now, you will have to flash SiyahKernel as tar file with Odin.
And yes, CWM recovery is included in the kernel (zImage).
Before flashing, you should backup everything important. Just to be on the safe side.
Some EFS backup tools require root. If you find one which works without root, then you should backup before flashing.
Otherwise make the EFS backup (and a nandroid/system backup in CWM recovery) after flashing SiyahKernel.
Then use TriangleAway app to remove yellow triangle and rest the flash counter.
When flashing stock kernel after SiyahKernel, you don't need to wipe anything.
You can wipe data, if you want to do a factory reset, or you can do the factory reset later (on stock) too.
And yes, after flashing stock kernel, you will be back on stock recovery.

I was going to root my S2 today as I have had it for a while and want to root and update my rom or install a custom rom. CF hasn't made an insecure kernal for KH2. A few users had the same problem and used KH3 as stated by CF but some ended up running into difficult problems and some had no problem.
Should I use KH3 to root or should I use another method. I only want to root gingerbread so I can back up app data. I might then factory reset and update the stock rom or flash CM10 and then restore the app data.
Try using siyah kernel, same process...flash via Odin but with siyah there is a .zip and a .tar make sure you choose tar

Firstly, CF-Root doesn't use insecure kernels, it uses modified kernels, but thats OK. Here is a link to a one click root solution made by a reputable developer: http://forum.xda-developers.com/showthread.php?t=1125414
Scroll down the first post and you shall find the instructions. I believe the second post has a link to all the insecure kernels, including KH2 (I checked), and if you scroll down that link a little more, you shall find your original KH2 kernel to flash back to stop the yellow triangle showing at boot, but if you are immediately flashing a custom ROM, that is fine.
This method however will not grant you ClockWorkMod so you can flash a kernel such as Siyah Kernel, make sure to download the GB kernel, not the latest ICS kernel! Here is a link to the GB kernel: http://www.gokhanmoral.com/gm/2012/03/19/siyahkernel-v2-6-14/
Flash this using Odin. Put the .tar file in the PDA section on Odin once you have put your phone in download mode, killed off any Kies processes on your computer, and click start. This will add a new custom kernel to your phone, granting you ClockWorkMod Recovery, allowing you to flash a custom ROM.
Before progressing any further, back up your phone by booting into CWM (home button + power button + volume up button).
Also, download EFS Pro: http://forum.xda-developers.com/showthread.php?t=1308546 This tool backs up your EFS folder which contains your IMEI which can be damaged easily when flashing custom ROM's and you don't want to do that!

What if I want to just update my S2 to the latest stock rom and not have a custom rom. Do I have to flash back to the original kernel to be able to update the stock rom? Once I update to the latest stock rom, will my phone still be rooted or will I have to root it again?
You would have to root it again. But Chainfire should have all the modified kernels for 4.0.3 ready for your use anyway.

So after I flash the insecure kernel to root my phone (gingerbread), shall I flash back to the original kernel?
Sent from my GT-I9100 using xda app-developers app
Yeah it stops the yellow warning triangle being displayed at boot. Your custom flash counter will increase but it can easily be reset by buying a USB jig off eBay.

So I should flash back to original kernel and then update to ics and then root again?

Or just flash Siyah kernel via Odin and then flash a custom ROM which should automatically root your phone. If not, just find a CF-Root kernel for your firmware and all shall be good.

There isn't a CF-Root Kernel for me which is why I created this thread to ask for the second best method to rooting a gingerbread S2 or if I should use KH3 CF-Root Kernel to root. I'm only rooting so I can back up app data using titanium. This is my first time rooting and flashing and I was going to root using CF-Root until I couldn't find a modified kernel for me.

Hi All
Please let me explain in detail:
1. I had original ICS and flashed CF-Root with ODIN
2. Flashed new JB-Polland with ODIN
3. Lost root access and CF apps
4. Re-flashed CF-Root, CF apps and root access granted
5. Opening CWM i get the following msg: "This version of CWM should be used with CF-CWM v1.1" Now from reading other posts, i think this error is due to CF-Root not supporting JB.
Therefore what are my options?
1. Can I flash a new root over CF-Root, that supports JB.
2. Do I do the triangle away and try to clear CF-Root
3. Any other suggestions?
Thanks in advance guys.
Whenever I'm flashing a ROM, I flash over the previous one.
I installed CF-Root, flashed MIUI, didn't like it so flashed CM10, didn't like it so flashed to stock again then reset my flash count to 0.
Or use it as is. Everyone who uses CF-Root with JB gets that message. You can still perform backups, updates and ZIP installs through CWM recovery.
Thanks Sleepycat, I didn't realise you could keep using it. Part of the message says some features have been disabled.
Running backup in recovery mode now and seems to be going sweet.
Thanks Guys
its just the app that's incompatible, not CWM itself.

Depending on what you are flashing, what is on the phone will be "overwritten". For example if you flash a kernel you will replace just the kernel, if you are flashing a full rom, everything that the rom contains will overwrite its equivalent in the phone (which is why you needed to reflash the root).
If you want to ensure you can get back to original state you needed to have done a nandroid backup at the beginning from which to restore later.
Hope this helps
