Did you try downgrading after a reset or sign out (anything but a full recovery one) while on 4.20? I don't think that one is completely safe due to the dictionary DB changes.
P.S. I can confirm that downgrading works if you originally upgraded from a version below 4.20 and haven't manually deleted the dictionary table.
