  In the literature, motivated by the observed peculiar neutrino mixing pattern
and a preliminary experimental hint for maximal Dirac CP phase (i.e., $\delta
\sim 3\pi/2$), a lot of flavor and CP symmetries have been proposed to help us
understand and explain these experimental results. However, for some
flavor-symmetry scenarios (see section~3.1), the leptogenesis mechanism is
prohibited to work as usual. To tackle this problem, in this paper we have made
an exhausitive study on the possibility that the renormalization group
evolution effect may induce a successful leptogenesis for these particular
scenarios. Our study provides some complementarities to the previous related
studies in Refs. [26, 27, 28] (see section~3.2).
