How To Flash CWM With TWRP Already Installed??

view story

http://forum.xda-developers.com – I recently installed the CM10 Unofficial ROM on my tf201 and the SU keeps denying Titanium BU and any other (su)app I try to use...this CM10 ROM came with TWRP as the recovery and I want to revert to CWM and flash a different ROM because I've had nothing but problems with this one... how can I flash CWM over TWRP? I never liked using TWRP for some reason...all I ever have is problems with it... (HowTos)
