Why would you flash 3.0.0.5 through ROM Manager, and then flash 3.0.0.6 manually? Why not go straight to 3.0.0.6?
three reasons. 1) i do not recommend using CWRM to flash permanent recovery images. I've see too many people on Cyangoen's web page have problems with just flashing it via CWRM. 2) He can do it with the Flash'd Script that True-blue made and by pass the ADB commands completely. Some people are unfamiliar with them 3) he can create a nandroid prior to upgrading in case something goes south.
