Rommanager , CWM on SGS2 - Galaxy S II Q&A, Help & Troubleshooting

Hello XDA-community,
I've rooted my Samsung Galaxy S2.
Model : GT-L9100
Android version : 4.0.3
Baseband : L9100XXLPW
Kernelversion : 3.0.15-L9100XWLPD-CL524746 [email protected] #3
Build : IML74K.XWLPD
I've read that I could get CWM on my phone by installing ROMmanager.
When I go in ROMmanager and use the option to install CWM.
It freezes around 95% , the app stops and give the option to quit rommanager.
After restarting Rommanager I see that i have "succesfully"installed CWM , but when I click on the start recovery my phone Freezes which only stops by pulling the battery.
What should I do to get CWM running.
There is a halve CWM on my phone , which I don't know how to remove.
And how do I get a working CWM since I need it for installing ROMS.
Also I dont trust ROMmanager atm so is there another app which could flash a rom , or is there a way to fix the rommanager?

Run away from ROM manager, it's not fully compatible with our phone.
You need ROOT access inorder to get CWM recovery.
Visit this THREAD for the safest rooting method
then flash this Siyah or Speedmod via CWM recovery in order to have a permanent CWM recovery (optional)

I am following the guide that you send me.
I've installed the CWM , but when I continue CWM blinks for a second resetting to the first option.
I have still acces to my phone or whatéver

I've found out that using the volume buttons makes it reset , but the touch screen works.
Now im backing up my phone and install root files.
But i get a message no sd-ex found and can't install the rooting file

If you try it before flashing a custom kernel, your device will be bricked. It's a known issue. don't try it before flashing a custom kernel
good luck

@Jokesy - Just a quick info..Even i did a backup using CWM backup and it was successful. I am on stock ICS 4.0.3 XWLP7.
I think the phone would get bricked if you try backup using CWM on a phone that has stock ICS 4.0.4. Correct me if i am wrong here.

You are partially right.
**If you're trying to do a ROM backup in CWM recovery**
1. Yes, the phone will be bricked if you are running stock ICS 4.0.4 ROM with stock/stock-based kernel
2. No, even if you 1. is applicable to you but you have a sane emmc chip.
-The only reason why I don't want people to risk it even after confirming their emmc chip is sane, is because I want them to be 100% safe.
I'll juststop here because Other points might lead to greater confusion.
