    A dirty flash keeps system data from the previous ROM. If the ROMs are not compatible with each other, you'll run into problems.

    A flash of rom over existing rom without wipe is known as dirty flash, generally followed for nightly or daily builds. You also need a set of gapps with backup script to survive dirty flash.

    Dirty Flash = Flashing over current ROM
    Clean Flash = Wiping EVERYTHING to make way for a new ROM.

    Dirty flash - wipe cache and dalvik, flash ROM and gapps

    Clean flash - wipe cache, dalvik, data and system, flash ROM and gapps

    A dirty flash will land you in deep trouble with the law (and with general society as a whole), whereas with a clean flash, you'd be considered an oddball.

    I always do a clean flash even if it's the same ROM... Takes away the headaches of trying to figure out the problems of a dirty flash.

    Someone should make a post explaining common terms floating in the forum....like seriously. Not everyone here is an expert.
    This thread was helpful by the way.

    I hear that... I'm feeling the pain again trying to dirty flash from CM12.1 to CM13. Themes always seem to break something for me. The same thing happened when I went from 11 to 12. Looks like I'm gonna bite the bullet and just clean flash it!

    clean flash isn't really clean to be honest you still have left over from existing apps.
