Well, if you are already rooted there's another way how ton install cwm recovery.
1) get terminal emulator from play store
2) copy cwm recovery.img to sdcard
3) run terminal emulator app and execute commands
$ su (allow root access for terminal emulator when asked)
# dd if=/storage/sdcard1/recovery.img of=/dev/recovery
That's it. Turn off phone and turn it on while holding Volume+. Should boot into recovery.
If that doesn;t work, get ADB and use "adb.exe reboot recovery" while phone is turned on.
You must have USB debugging in development options for this to work.
