  We study evolution of the braneworld Kerr--Newman (K-N) naked singularities,
namely their mass $M$ , spin $a$, and tidal charge $b$ characterizing the role
of the bulk space, due to matter in-falling from Keplerian accretion disk. We
construct the evolution in two limiting cases applied to the tidal charge. In
the first case we assume $b$ = const during the evolution, in the second one we
assume that the dimensionless tidal charge $\beta \equiv b/M^2$ = const. For
positive values of the tidal charge the evolution is equivalent to the case of
the standard K-N naked singularity under accretion of electrically neutral
matter. We demonstrate that counter-rotating accretion always converts a K-N
naked singularity into an extreme K-N black hole and that the corotating
accretion leads to variety of outcomes. The conversion to an extreme K-N black
hole is possible for naked singularity with dimensionless tidal charge $\beta <
0.25$, and $\beta \in (0.25, 1)$ with sufficiently low spin. In other cases the
accretion ends in a transcendental state. For $0.25 < \beta < 1$ this is a
mining unstable K-N naked singularity enabling formally unlimited energy
extraction from the naked singularity. In the case of $\beta > 1$, the
corotating accretion creates unlimited torodial structure of mater orbiting the
naked singularity. Both non-standard outcomes of the corotating accretion imply
a transcendence of such naked singularity due to nonlinear gravitational
effects.
