[Q] Rooting 4.0.4 - Galaxy S II Q&A, Help & Troubleshooting

Hi..I went through all the guides and stuff..I wanted to install a custom rom on my phone..n I am quite new with this phone..But I have installed custom ROMs on my previous xperia arc s..so i am familiar with the procedure..the only thing m a little confused and worried about is how to root my phone..I am on 4.0.4 and have read that mistakes may lead to hardbricking of my phone..so i wanted to be careful about it..
Now the confusion I have is that while some users have advised to get a CWM recovery and rooting to be done first and then Siyah kernel to be flashed as in the following guide..
http://forum.xda-developers.com/showthread.php?t=1501719
Also some have advised to flash a siyah kernel straightaway through ODIN without doing the above procedure..
I wanted to downgrade to 4.0.3 before going for a custom ROM just to be safe..I wanted to flash the leaked JB XXLSJ based custom ROMs on my phone..so I just wanted help and clarity on which method is better and also I am not sure if Siyah yet works with XXLSJ ROMs..so what is the kernel that I need to flash and all..

You don't need to downgrade to 4.0.3, root, flash CWM recovery and then SiyahKernel.
After flashing SiyahKernel on your 4.0.4, your phone will be rooted and you will have CWM recovery. And SiyahKernel is "safe" from brick-bug.
Just flash latest SiyahKernel (v5.0.1) and then you should create a nandroid backup in recovery - just to have a complete system backup of your current ROM.
Then you can flash the custom ROM in CWM recovery - stick to the installation instructions of the ROM. You may have to wipe data/do a factory reset.
Good luck !

Hey thanks a lot..btw after rooting and getting CWM i can flash siyah directly from the CWM only right..or is Odin better?

Oh and one more doubt..i dont have an external sd as of now..can I do the update through internal sd storage or USB storage as they call it??

You can flash Siyah Kernel via ODIN or CMW whichever you want.. yes you can use USB Storage in CMW

Siyah.zip=cwm
Siyah.tar=odin
You can also use mobile odin

Cool as in not overheating ???
a wipe and flash of stock rom will remove custom rom .
Root and custom roms void warranty and have a slight risk of bricking the phone .
But are usually recoverable .
You need to read the faqs and guides and understand the CM9 instuctions first .

to flash cynogen rom first u have 2 root ur phone please find the thread in original devlopment section regarding the same
u can reflash ur stock rom by dwnld the releavant .tar file adn flash the same thru odin
You can re-flash the stock rom, but just be sure to know which one is your stock rom. Go to settings, about phone and record the info there to be safe. Also back up your current rom using CWM.
There are always some risk in flashing a rom. Some people dont read instructions and cause problems on their phone, some people flash a rom not built for their phone (i9100 VS i9100G), etc.
Yeah i have rooted my device with cf-root. Thanks guys , i'll read some guides about cyanogenmod and flash it.
If your are currently on GB stock rom, Cyanogenmod developer recommends to install ICS bootloaded first,
You should be able to reflash your Stock ROM veriosn from ODIN, as well as custom roms from CWM...
What is bootload? o.o
My current firmware is ICS LP7

No they say to have below some specific ics boot loader, no mention of upgrading your gb boot loader, unless they changed it.
Plus I yet to had any issues with the latest ics or gb bootloaders..

I think he meant boot loader.
But since you already have ICS, you won't need it. Just take the latest CM9 nightly (or ROM based off it), and flash (you'll have to wipe cache data and dalvik too eventually). Make sure you make a full backup of your current stock ROM through CWM as well.

I refer this guide actually : http://forum.xda-developers.com/showpost.php?p=20841817&postcount=1
I dont know its outdated,
as others are sharing their experiance that you could flash CM9 straight away from your CWM since you are already on LP7 with ICS Bootloader.....
I don't get it... What is a bootloader?. I mean when i flashed with ICS LP7 i didn't put a file on bootloader. I just loaded the PDA .tar file and flashed it..
Soo that means that i have to reflash the stock rom with bootloader?

I dont know the ICS package you flashed had an ICS Bootloader already...
I just gave you the link for Original CM9 developers guide...
Just wait for others recommendation who have already flsahed CM9 from CWM....
Hmm thanks . But i have read in the guide that i can flash it with odin , do i still need the bootloader?

[Q] Rooted S2 but no CWM?

Hi,
This international S2 came out of the box running a stock ICS 4.0.3 and appears to have root access, also has "SuperSU", however it has the stock recovery mode.
I'm interested in replacing the stock recovery mode with CWM so that I can install custom ROMs but my device is already rooted and I'm quite confused about this, should I just go ahead and flash a CWM kernel?
And also,
Do I have to match the kernel to the ROM that I'm going to flash (AOSP, AOKP, XXLSJ)?
Thanks.
Just flash Siyah, Dorimanx,... with Odin.
And yes some Roms doen't work with some Kernel. For example I had problems with Siyah and CM10.1

I got a s2 4.0.4 (no root) and would like to install the disaster custom rom.
Because i have 4.0.4 and can brick my phone i need some helps/tips..
So as i understand i need cwm to flash the custom rom.
To get cwm i need root. Well, which root methode should i use?
I want one with cwm and supersu in it.
Oh, and after i have root on the 4.0.4 and flash the 4.1.2 custom rom do i keep my root?

Just dwnld the 'Siyah kernel v4.1.5 or v5.0.1' (tar file for ODIN) and flash the same thro 'Odin' on ur pc.
It will automatically Root ur phone and install 'SuperSu' and latest CWM recovery for u.
then using the cwm recovery of siyah kernel u can flash any custom rom of ur choice.
after flashing the custom rom based on 4.1.2 u wont loose ur root
ps- once u install custom kernel like siyah ur phone will be safe from the 'Brick Bug' issue for sure
Flashed the Siyah Kernel.
About to flash custom rom
but got one finally question.
The custom rom; http://forum.xda-developers.com/showthread.php?t=1498017
Says it has philz kernel or whatever
so can i still flash it? and does it change my kernel?
Does it have a effect on me?

it will not have any effect on u though

Of course you can, there are a couple of threads/posts about it. You just need to read them.
And don't worry about the bootloader.

Can i get a conform instruction on how to do this?i prefer not to do this with odin..because i already have a custom recovery...my recovery is CWM 5.0.3...do i need to upgrape my recovery first?
So you want to flash it via CWM, that's a completely different question.
You can also search for that.
Don't wanna flash with odin?
Mobile Odin might be the best tool for you.

i already search for it...i found
1. Stock rooted deoxed rom 4.1.2 <<< -- to install this i need CWM for JB
2. Root on stock recovery <<<< -- to install this i need stock rom and stock recovery
3.CWM on stock recovery <<< --- to install this also need stock recovery
-stock rom and recovery mean using odin...and i dont want to use odin...
From all thing above..i need to know how to do this with ICS CWM that i already have....IF there is anyway pls let me know...
sorry for my bad english...
can at least give me a link to where this instruction on how to do this??
Check out Mobile Odin.
And I think you want the deoxed ROM via CWM.

Step 1 - flash CF kernel which is appropriate to ur baseband with Odin
Step 2- Flash cutom rom what ever u want
Step 3 - Flash Gapps..
Thats all :good:
You can flash CWM and then the custom ROM now itself, without upgrading to ICS. Just make sure you flash the correct rooted kernel for your baseband version. Don't directly flash any CWM or use ROM manager. Good luck!

My details
Baseband version - I9100BUKI1
Kernal Version - 2.6.35.7-I9100BUKJ3-CL647431 [email protected]#2
Build number - GINGERBREAD.BUKJ3
So can anyone give me correct CWM recovery to my S2 ? (I just want to flash kitkat rom.. )
And you can't search for this why exactly ? You've been here more than long enough to know how things work.
Flash Gustavo's kernel first and then follow instructions on the omni thread for flashing as a first time user.
Search around and you will find everything here itself.
I'd suggest flashing the latest stock rom via Odin, ms1 I believe. Then flash philz kernel. Then boot into recovery, (while your new rom cwm zips are on your SD card) format system, preload, data and cache. Then flash the omni rom zip, and the correct gapps, and any other mods you would like.
