[Help] Rooting + Custom rom - Galaxy S II Q&A, Help & Troubleshooting

Hey guys,
I have just need some help.
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?

Yes, u can flash it and the Kernel (philz) that comes with that rom will replace ur Siyah kernel for sure but u wont loose ur root
it will not have any effect on u though
do follow the install instruction for a successfull flash of the rom.
Cheers!!

Thanks, it works!!

u mean stock GB rom or the custom One?
if its stock GB then dwnld the firmware(GB) and flash thro ODIN instead after following the ODIN flash instruction of the same.
if its custom GB rom then u can flash the same thro CWM after reading the installation procedure in the OP of that rom thread

Okey , all is workin great , thank you for fast respound
Im was afraid because it is my friend phone
Actually you don't need root/custom kernel to flash a rom.
1. Get this
2. Get the rom zip you want
3. Place both in external sdcard
4. Go to stock recovery (when phone is off, hold home + power + volume up button)
5. Flash the first zip (recovery)
6. New recovery opens
7. Do a backup to be safe
8. Wipe data/cache or factory reset
9. Flash the from zip
8. Reboot
9. If you need to go back to ICS do a restore
With this method you will not have the yellow triangle or custom binary

[Q] Rooting 4.0.4

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

[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

just flash the Siyah kernel v4.1.5 or v5.0.1(tar file for ODIN) using 'ODIN' on ur PC to get proper wrk'ng CWM app installed on ur phone
Then use Siyah's recovery to flash any custom rom of ur choice

Xperia mini pro root CWM Recovery after

Hey guys long ago I rooted my xperia mini pro and put CM 9 or 10 then I went back on Stock then again i put some radom kernel and and rom, then i wanted to put a rom here from te forum but when I put the kernel and try to go to recovery it wouldn't start the recovery the screen is just black
So i went back to stock !
now my question is how do I root again X_X
and how do I put CMW reocvery, because I want to put this : http://forum.xda-developers.com/showthread.php?t=2220537
maybe you can find here what you search
http://forum.xda-developers.com/showthread.php?t=1842366
and 4.1.2 is not ICS its JB
Since u tried cm, I am sure ur bootloader is unlocked.
So the easy way to root now would be to flash any custom kernel. It will be prerooted.
If you still want ti retain the rooted stock rom
Flash kernel and flash stock excluding kernel
Or flash stock and then flash kernel

Yes most (I believe all) custom kernels will have cwm ( or twrp,) so yes.
Try goin to dev section and find the list of kernels in stickies and find a jb kernel.

[SOLVED]Flashing CWM recovery on S2

HI
I have Galaxy s2 with android 2.3.5. I want flash OMNI 4.4 rom on it..but before that I want to flash latest CWM recovery on my S2. And also my S2 doesn't have root access So the problem is
Can I flash latest CWM recovery when my S2 have android 2.3.5. ? or should I update official ICS from OTA before flash ?
(I'm planning to use ODIN to flash 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.
