[Q] The safest way to root Galaxy SII i9100? - Galaxy S II Q&A, Help & Troubleshooting

Hi there,
Please could someone post relevant information on how to root the Galaxy SII, I have searched a lot of threads and can't seem to find a reasonably safe solution to my question. People say its not possible to root a Galaxy SII lately due to a hardbrick bug in the chip. Please could someone enlighten me on this topic and tell me if it's safe or unsafe. I will post the details on this thread to the best of my knowledge.
Ok here goes;
Model number: GT-I9100
Android version: 4.0.4 (ICS)
Baseband version: I9100XXLQ6
Kernel version: 3.0.15-I9100XWLPT
Build number: IMM76D.XWLPT
Also, I have installed the eMMC brickbug check app from the play store and here is the result i was given;
Brick Bug ? No. Sane chip (no idea what this means but I'm guessing my chip is safe to just flash any Kernel?)
I am just looking to root for now and possibly flash a custom ROM in the near future but at the moment I am happy with the stock firmware but I just want to be able to use Titanium Backup, Superuser & ROM Manager but i am unable to do so until I have rooted my Galaxy SII.
I'm not new to any of this because I previously had a ZTE Blade which I rooted & flashed custom ROMs myself, this was a walk in the park compared to the Galaxy SII. On threads which I have browsed through, some people state to use Siyah Kernel, would this be safe to flash through Odin? Or maybe I could use CF-root.
thank you for reading my post & I'd be so grateful if someone could provide links and/or instructions. Much appreciated!

http://forum.xda-developers.com/showthread.php?t=1746794, use that, method 1 always works.
oh and if you just wanna be 100% you wont be affected by brickbug, just flash siyah kernel through odin, that will give you root + CWM recovery
In my opinion, you should go for siyah but pick whatever u prefer

Thank you Poroto, I will probably try the method 1 posted by Phil3759. That looks kind of safe but I'll read through that thread you posted first before I decide. I really appreciate your help

No worries, just remember not to wipe anything on stock 4.0.4 kernel under any circumstances.

Be careful with the kernel you flash, be sure its compatible with your device. (google is always a good friend)
About "how to" topics, I suggest you do a search on the "general" and "q&a" categories, there I'm pretty sure you'll find a variety of guides and tutorials for new users.
Best kernel and rom don't exist, its all about what you need and what you're prepared to sacrifice/do in your device. Some roms have bugs that other don't, some are faster but drain more battery, and so on. So try them yourself (remember what I said about compatibility, and also do backups).
I hope this helps.
hi tnx for the reply are you also using a not international version??
No, I'm using the S2 international version, but in the past i've had other regional models (other devices, not exactly s2). So I know what I say when I say to check compatibility first and do backup.
Devices may differ from hardware to partition sizes and other stuff. Try googling your actual kernel or find out what rom is that, its a start.

look for siyah kernel, i believe it is version 5.0.1 then install it with odin. but first, you have to know how to use odin. you can learn that by googling how to use desktop odin. make sure you install samsung kies on your computergood luck.

Build number: IMM76D.WBLP5
I've looked around the net, havent found anything about rooting this version/build number combination.

You don't need no combination. Search on how to root ICS. Hint: "si%@h k&^n&1".
Sent from my digital submersible hovercraft.
This might help you.... try it http://galaxys2root.com/galaxy-s2-root/how-to-root-galaxy-s2-i9100-icsandroid-4-0/
Thanks , Yeah I wasn't sure because searching for how to root the SII I saw pages like, "how to root XXLQ5" So i was wondering if baseband versions or build numbers have different ways of going about rooting them

You may check this website
There are also many useful information about your phone.
Why are you linking people to guides on other sites ?
It's a bit hard for other people here to help this person with that method if they get stuck (as if you're going to be around 24/7). I'm certainly not even going to look at anything related to rooting on another site for that reason, plus chances are the information has been lifted from here anyway.
There is a wealth of information on this subject on this site, please refer people to that in future rather than info off site for such a basic query.
