Hi im using Samsung Galaxy S2 rooted stock ROM ICS 4.0.3 ,
GT i9100
baseband version : I9100DDLPA
Kernel version : 3.0.15-i9100XWLP7-CL340913
Build number : IML74K.XWLP7
I have a noob doubt ...Does installing Custom Kernel removes the user data +apps ??
And my whole settings ?? Or is it just like Rooting my phone ( Doesnt affected anything-even my BG image :laugh: )??
Please help me ....Im planning to Install Siyah Kernel since many of them using it and its awesome kernel itseems ....Googled
Is Siyah compatible for my version ??
Please Help me XDA
No, all your data is safe... until something goes wrong and you will be forced to wipe your data/factory reset. But this are rare incidents.
Just put few kernels in your internal sdcard card root folder, be sure that kernels are properly downloaded (verify md5 signature) and flash it with cwm or mobile odin. You can also use odin on your computer but binary counter will be increased.

The thing is i dont have CWM so only installing custom Kernel .....I only have stock recovery .....Clockworkmod is not available in CWM website it says the download is not available now ...Im looking to install CWM6 ......
The imp reason for installing custom rom is to get CWM6 .....
Is there any way to flash custom kernel without CWM and Odin ?? With stock recovery ??
Or please suggest me anyway to install CWM without installing custom kernel for S2 i9100
Mobile odin (free version will be enough), if your phone is rooted.
Select kernel with cwm build in (Siyah...) and flash.

custom ROM/KERNEL cannot be flashed thro Stock Recovery ma8. for that u need a wrk'ng CWM Recovery.
U can flash the .tar file of siyah v4.1.2 using ODIN from ur PC, u will get the latest 6.x.xx recovery installed along with it.
Use Odin on your pc and flash the .tar archive of the Siyah Kernel (4.1.2 or 4.0.1).
Unless something really rare happens, this shouldn't affect your user data. Remember to wipe cache and dalvik after flashing the kernel (you will have CWM just after flashing).

Installing a new kernel doesn't affect any of your settings.
You should wipe cache and dalvik cache to ensure integrity, stability and no program errors

Flashing with Odin is easy and preferred by most ppl, but I don't wont to have a yellow triangle and incrased binnary counter (never had it). I preffer tools or ways more complicated but still safe to root or flash. I'm using Odin only when I want to perfectly debrand phone or wipe him to factory state with stock firmware.
But S2 is so user friendly that it is a sin to rape him with Odin all the time. All you need is:
1. Fake recovery to root any ICS based stock firmware
2. Mobile Odin (or something like that) to flash custom 'preclockworkmoded' kernel
After that you can, and you should, flash averything from cwm recovery (all .zip based files) or tools like Hellcat's kTool or Chainfire's CWM tool or mentiobed before Mobile Odin (to flash anything you want - .zip .tar .bin wit md5 hash or without it)
Use Odin only when you don't have another choice. You will not be bored by drivers, data connections, is it see or not see by explorer or Odin, etc.
It is mobile gadget, use it's wireless power.
Even for data transfer there are great aps (AirDroid, ES File explorer, Solid explorer etc.).

I've stuck by the Siyah kernel for the better part of this year and always held it in high regard.
If you're keen, I encourage you to dabble with ExTweaks for a solid day as the outcomes can be very useful. Namely, improved performance and better battery stats

Root with CF-Root in stock recovery + Back up your existing kernel
Full Un-CF-Root and Restore your previous kernel
No need to a PC, no Odin, no Yellow Triangle or counter
Only one file flashed in stock recovery
Credits to Chainfire: http://www.chainfire.eu/
If there is one popular root method, it is for sure the CF-Root kernel one.
So, do not miss the original CF-Root thread here: http://forum.xda-developers.com/showthread.php?t=1103399
Advantages of CF-Root kernel are:
Keep a stock based kernel
Add Root with Chainfire SuperSU
Get insecure kernel for developers (Root acces for ADB in recovery)
Get permanent CWM5 and Chainfire CWMManager application
Get customboot.sh support
Click to expand...
Click to collapse
Original releases need to be flashed in odin, so you need a PC.
After flashing in odin, you get a Yellow Triangle and increase your custom flash counter. You need a special application called Yellow Triangle to reset these.
If you end up with a bootloop after flash (this can happen if you flash the wrong kernel) or you want to change your mind, you have to look for your previous kernel to flash it back
Unrooting needs you to flash a full ROM in odin, simply flashing previous kernel will not remove root.
In this thread, I got rid of these issues, putting the CF-Root kernel in a zip that can be flashed directly as an update in stock recovery.
The CF-Root files included here will backup your existing kernel to external sdcard (Kernel_Backup.img)
Later, you can restore your Kernel_Backup.img and fully unroot using the attached CF-Unroot file
CF-Root + Backup existing kernel files:
- Download the CF-Root zip file corresponding to your Kernel.
- Put the CF-Root zip file on your External SD (needed for stock recovery).
- Boot into stock recovery (volume up+home+power), and select "apply update from external storage".
- Select the CF-Root zip file from external SD
- It will backup your current kernel to Kernel_Backup.img file on the external SD and apply CF-Root for your kernel

CF-Root-SGS2_XW_NEE_LPX-v5.6-CWM5
CF-Unroot + Restores your Backup Kernel from SD Card
To completely remove CF-Root without having to flash a full ROM in odin, use the attached CF-Unroot.zip file
It will restore your Kernel_Backup.img file from external SD and remove all root files and CWM Manager application
It is unsigned as you are supposed to only use it on CF-Root Kernel when you have a Kernel_Backup.img made with previous method
FAQ / Fix for common issues
After flashing CF-Root kernel, you end up with no root access:
This is not caused by my script, but can happen even under odin when you flash many kernels
If it happens to you, just run the attached CF-Root-Fix.zip attached here. It will put superuser and cwmmanager application in /system
You used my CF-Unroot.zip file without the Kernel_Backup.img file in ext-sd
You should have read the instructions!
But do not worry, the script should now abort and nothing is done
You can use the CF-Unroot script to flash any kernel over CF-Root kernel
Just extract the zImage or boot.img file from the kernel you want to flash and rename it to Kernel_Backup.img
It can be useful to quickly try some kernels. Keep in mind that mobile odin can also directly flash zImage files.
A last one reserved for FAQ / uploads
Done

No, this part is easy. Can be helpful for many people not having PC, or when you're on the road, flash a ROM and want a root...
I am looking to make CWM permanent... but this moves me to custom kernels, while all my guides were about keeping stock kernel
Also, it will need a kernel build for each kernel version, no other way till now. So people will need to rely on me to build each kernel. Not sure I have the time for such a support.
Looking to release only a few kernels maybe.

Yeah CF-Root is most popular because it was for long the only reliable method, but since Rachmat3 came with the injection and you polished it to current state of art perfection makes it little bit obsolete Why to bother with insecure kernel (and till now with counter increase and yellow triangle [not anymore as sorted by you again ]) when you can do it in such easy and noob proof way?

Insecure kernel is useful for dev purposes and also to recover phone in some circumstances
CF-Root also comes with fixed cwm and a cwm manager, useful for dev and crazy flashers.
Also, i forget to mention customboot.sh and init.d support
So, depends on each one and its needs

Temporary busybox is now extracted to /tmp instead of /sbin. This could cause later scripts with /sbin/busybox to fail

Previously, if you used CF-Unroot without a Kernel_Backup.img file on external sdcard, root files were deleted and you were instructed to flash the CF-Root fix file. Now, if you forget to put the Kernel_Backup.img file, script will abort and no changes are done

Searched forums, only similar thread is for Galaxy Tab. I'm assuming it's not relevant enough for me to follow it directly.
If possible, explain it like I'm 5:
What is the safest way to install a custom ROM? (Ideally, I want to install CM9 and later CM10 when it is more stable). I've seen people saying to flash Siyah kernel first, then do whatever afterwards. How can I do this? Almost a complete noob here, what buttons do I press in Odin and what procedure do I follow to flash a safe kernel then a custom ROM.
NB: USB is a little buggy, on-device flashing preferred for that reason.

Yes,, you need to flash a custom kernel.
1. First post your full ROM details
2. Can you confirm that you have ROOT access?
3. If your USB is buggy, you still flash Siyah kernel using mobile Odin, or the temporary CWM recovery. Root access is needed.
Thanks for the really fast reply.

1. Stock 4.0.4 from samsung; Kernel version 3.0.15-I9100XWLPT-CL941023
2. 100% have root access. Running Droidwall (which is working) among other things
3. I'm unsure if it's the phone, USB port or drivers which are buggy.
Is it possible to get a definitive procedure to flashing Siyah with mobile Odin? (presuming it's safe to do so). After that, is it safe to just flash the full CM9 ROM with CWM?
The safest way to avoid the emmc bug is to flash a custom kernel. Like siyah or dorimanx. If you have root access, and CWM, you can install one of them. Do you have CWM? well then follow these steps.
-Download a custom kernel. Eg the .ZIP file of the latest version of siyah kernel for S2 from gokhanmoral's site.
-Store it in your internal SD card on your phone.
-Boot into recovery. ( Vol-up + Home + Power button )
-Go to: install zip from SD -> install zip from internal SD
-select the kernel's zip file
-select 'yes'
Let the phone reboot once your done. You should have a custom kernel and no chance of the emmc bug bricking your phone.
The reason I suggest using CWM rather than Odin, is incase you have a faulty usb port, that might pose a problem while installing via Odin.
Hope this helps.

I have root access but no CWM. When I originally rooted the phone the sole reason was for droidwall.
Is it safe to install CWM and flash a custom kernel as long as I don't do any data wipes?
Can I install a custom kernel and have the phone as is (without noticeable differences) until I flash a custom ROM?
What happens to SuperSU and it's settings when I flash a custom kernel (and will I still have root access)?
Finally, if anything screws up what is the recovery procedure? I don't have a copy of this kernel/firmware as I installed it as an OTA update.

You can make a nandroid backup with cwm. That will create an image of the current state of your phone to restore incase necessary. Just make sure u have a custom kernel and follow steps mentioned in the guides on this site and you shouldn't need to worry

I've installed Mobile Odin (v3.35)
I've installed FlashKernel (v2), there was a v1 higher up the page but I'm going to assume that v2 has some bug fixes or other updates (please correct me if I should be using FlashKernel-I9100-v1 rather than v2.
Now, I'm not sure where to go: Should I install CWM or flash straight to Siyah kernel. CWM seems safer since I can do a backup and hopefully have some access if anything goes wrong.
How do I flash CWM with Mobile Odin? Which flash (mode? partition? not sure about terminology here) do I choose (Kernel, ..., etc) and probably importantly: which version of CWM should I be using? I've seen many threads talking about CWM4/5/6. Are they simply updated versions? designed for different kernels/android versions? Are there any specific versions which try to mitigate the superbrick bug?

Flash Siyah kernel straight using mobile Odin. It comes with a permanent CWM recovery too.
Todays almost all kenels are safe
so resure yourself
And be careful, when you flash rom in recoverymod
if. battery is off when flash rom, your device have hard brick
so you must have change your main board

Siyah kernel flashed and working perfectly. Didn't realise how instant it would be. Thanks again to everyone, this community is friendly and helpful.
I'm just wondering as I'm in the same boat as the OP was once in.
When it comes to choosing the Kernel does it matter if its JB based or ICS because I'm on the stock ICS rom.

You don't have root access, right? Flash a custom kernel with Odin (like Siyah), but make sure it's compatible with your firmware. So if you're flashing Siyah, flash the version (v4 and/or v5 is what I thought) that's meant for ICS, otherwise your phone won't work.

Actually I used another method that allowed me to gain root access, but I'm on stock kernel and rom. I kind of feel safer when flashing a kernel and rom from recovery.
So say I use Siyah ICS for my Stock ICS rom, If I wanted to flash a JB rom like the one leaked from samsung would I need to also flash the Siyah kernel for JB too?
I have I9100T as well and 4.0.4 on it, what do I do? Will Siyah work for me?
Hi to all seeking assistance because i cant update my kernel to SiyahKernel S2-v5.0i planning to dual boot it with Ressurection Remix Rom my current configuration for my phone is as follows, thanks in advance
Unit: Samsung Galaxy S2 GT-I9100T
Rom: cm-9.1.0-galaxys2
Kernel: CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5
How is anyone supposed to help with absolutely zero information from you ?
We need to know exactly what you've done/are trying to do/what steps you're following, at what stage it's not working, etc, etc. In other words, as much information as possible. People here aren't mindreaders.
I was trying to update to this kernel Siyah-s2-v5.0i-CWM i have used Odin, but it fails.

Cause odin uses tar files not zip files... Try flashing the zip file in cwm recovery..

Before i do the flashing in cwm recovery should i delete some stuffs first like devlik cache? or i just flash it right away from cwm recovery

Normally it's not necessary when you flash only a kernel. However if you do that (up to you) it will not be harmfull for you phone.
What I do always before flashing a kernel is wipe cache and dalvik cache (even as I said it's only optional).
However it's one important rule: When you are on stock ICS 4.0.4 rom /kernel and your eMMC chip is brig bug susceptible then better not to wipe anything but as soon as possible to flash a safe custom kernel like PhilZ-CWM6, Siyah or Dorimanx.
My friend wants me to flash custom rom to his s2.I have xperia x10 and galaxy nexus with me.Both i have flashed.So i have some experince with flashing but i dont see bottloader unlocking here or one click root ad all so i wanna confirm the steps here beore i do anything stupid
so are these the steps:
1.Root your stock phone with CF-Root 5.6 from http://forum.xda-developers.com/showthread.php?t=1103399
2.Then copy GT-I9100 Resurrection Remix JB v3.1.3 from http://forum.xda-developers.com/showthread.php?t=1436854 to the sd card
3.Get into cwm recovery and flash this rom after a clean wipe
4.Flash Dorimanx 7.44 after a reboot
Is this it?

Yeah, all good but, have you read this?
Is your device a GT I9100? Are you on 4.0.4? Got the brick bug? You know siyah is a safe kernel?

The thing is where you're flashing from.
And yes, only 4.0.4's kernel's dangerous.

If you want to go from stock ICS to stock JB you have no need to root.
All you do is simply reboot into download mode (Power on using Volume Up + Home + Power) then flash the JB md5 file via ODIN.
Once you have flashed the file you may find system wont boot into rom (this is normal). Just reboot into download mode and flash latest version of Siyah kernel (.tar file) which will be Siyah v6 beta4 (or above). This will give you cwm recovery, better battery life, root access, SU etc.
Go and have a look at some topics/search etc, All the info you need is already on here and if you try and take some shortcuts you may run into problems or even possibly brick your device so take some time and learn.
PS. Yes the eMMc brick bug is part of stock 4.0.4 kernel so just dont go into stock recovery. You can also brick device by your flash process getting interrupted so make sure you have drivers installed correctly (install kies) and taht you're not running any other programs while flashing and also that you have at least 55% battery.
It's a very good thing you are reading before getting the bad boy you intend to flash.
See the thing about this bug is when you make a back up, wipe things up from the recovery, and flash via oding. Once you do the wipes, you are kinda screwed.
Now, you got a couple of choices here:
1) Your device arrives with 4.0.4 ICS, flash siyah kernel (I'll get you off the hook).
2) Arrives with 4.0.3, you are good to go, no danger.
3) You can try mobile odin, it flashes with its own kernel and, apart from being fast, it's easy.
4) If you get a gingerbread version, you good as well.
That being said, I'd advice you to play with it for a couple of days instead of flashing right away.
Check out some videos, read something about ExynosAbuse (It'll get you rooted with one click) and revolv around the q&a section looking for "not to do list".
good luck and remember, keep on reading.

Thanks a lot for all your help
the ressurection remix rom i downloaded came as zip file.I can flash it from cwm itself right?
and regarding the kernel im a bit confused between siyah and dorimanx .I know it depends on phone but what would u suggest?ur personal choice
and i need one more help.I need a vanilla jb rom.Not too much bloatware and with less bugs as possible and tweaked for performance and battery.The problem is net speed is very very low...trust me..i cannot try most of them unless i wait for weeks.So if anyone can suggest i can download that alone and do

I am about to install the international S2 JB ROM, and want root. The solution I have seen so far is the Siyah Kernel (6.0b4/5).
My question is this: If that kernal installs root, will I lose root if I change back to the official kernel that is inside the Firmware download (zImage)? What I might need is the CF-Root kernel, but I can't find it for JB (yet). Is it just a case of waiting for this?
I'm not familiar with ADB but am willing to teach myself, if this would help once I change to the siyah kernel (have looked at the quick root guides here: http://forum.xda-developers.com/showthread.php?t=1075278) but all the downloads are flagged by both Chrome and Avira if I do decide to continue past the chrome warning)

after installing siyah kernel v6.0b4/5 by flashing the tar file of the same thro ODIN ur phone will be rooted with the latest CWM recovery installed.
if u flash back the original kernel (zimage) again thro ODIN u will not loose ur root but it will be limited in its functionality

Thank you very much for your quick reply. I see now, the recovery seems to be part of/linked to the kernel. But I should still have superuser for use of titanium backup?
The only question I asked is: Do I keep root/busybox/cwm recovery
Lol of course you'll lose root and cwm, common sense. You will be flashing a new ROM package, new everything.
The only way to keep root (doesnt actually keeps, roots while flashing) is mobile odin.
I've found the answer, I do keep root, you were wrong.

Thank you very much, by "limited functionality" I assume you mean that there will be no cwm recovery, still that's good enough for me Thanks again
