Sorry for being even later, but after flashing a RM, the phone can take 10-15 minutes to finish booting. It has to generate an additional file for each app in the phone and, depending on hoe many there are, and whether you included the CSC file n the flash or not (not including it leaves all your files intact) ... You may start seeing "Updating 1 of 250" ... "Updating 2 of 250" If you see that, go for a long leisurely lunch and hope it'd finished when you get back. (And plug in the charger or PC - you don't want to run out of battery during a ROM flash.)
