If you are referring to the CF-Root post, then you didn't do it right. Not trying to be mean or a jerk... but if you followed the instructions to the letter, then you would have root, and you would have CWM recovery.

1: rom manager dont work on GS2
2: if you flashed cf-root using odin you should have cwm and cwm menu and Su in files when you reboot.
3: when you say recovery not working what do you want to do?

---

Did you flash the appropriate kernel?
I had the exact same issue when I first rooted my phone using superoneclick. I then did a cf-root and everything worked well so there is something you must be doing wrong...

When i boot into recovery it gives this error "E:falied to verify whole-file signature"

---

This might seem a stupid question but i'll ask it anyway.
Do you have a Galaxy S2? As your current device sig shows an HTC.

toggle off the verification option.
get the file again as it might be currupted.
file should be cwm compatible zip.

Dude try to install from the very beginning
Make sure you have all the drivers installed on your PC (install kies for this first)
DOwnloaD ODin
Exit Kies if its running in background
ON your MObile
Factory Reset it from settings
Let it boot
Enable USB debugging from developers options
Download 4.03 official roms from SAMfirmware
Install using ODIN
Search for an appropriate CF root kernel..
install it AFTER you have an updated new rom installed completely
DONOT install CWM from any external sources as its already in CF root kernel
WHen you boot after installing the rom go to SU and update it
then go to CWM and grant permission

You realize he started the thread 7 days back, and yet he replies today with how to do basic stuff..... its better for him to learn first, believe me its much better for him that way otherwise he is sure to brick

---

AFter YOu root it using CF root there is no need to install ROM manager and CWM from it....CWM automatically comes with CF root...
After installing rooted kernel just go to recovery mode
1. Switch OFF
2. Hold volume up + menu + power button
