i always wipe... with all the files that are getting changed, that's what i would suggest... wiping cache/dalvik should be fine...When going from one dynasty theme to another can I just flash over it? Like if I wanna come back to this from banana
i've had issues in the past with dirty flashing so i just make sure it's all clean each time i flash a theme!
i will say that all the files are the same with just the changes in colors... so you should get away with dirty flashing w/o issue!
