Okay guys, now the explanation what i've done:
I flashed the normal CWM as BOOT.img, cause flashing as recovery partition didn't worked.
When u do that, make sure u have all files u will need (root.zip, maybe CFW) ALREADY on your internal sd, because adb is broke because it's not the recovery parition, it's your boot system now.
Also you will need the superboot.img from here
In case u got ur recovery menu working , root and CFW flashed, turn off your phone and restart in bootloader by pressing Power and Volume DOWN. Than either flash superboot, if no custom FW was applied, Or flash boot.img from your CFW you've flashed seconds ago. Then reboot and wait a moment.
You can ignore that red label in the bootscreen, just wait until your phone botted up and enjoy root, or your CFW.
Any questions left?
