In the framework of Multiple Point Principle (MPP), where the existence of the two degenerate vacua of the Universe: the first, ElectroWeak vacuum with $\approx 246$ GeV ("true vacuum"), and the second at Planck scale $\sim 10^{18}$ GeV ("false vacuum"); we investigated the gravitational black-hole-hedgehog's solution with magnetic field contribution in the GraviWeak unification model described by $f(R)$ gravity. We have considered the phase transition from the "false vacuum" to the "true vacuum" and confirmed the stability of the ElectroWeak vacuum. The "false vacuum" defect configurations for the black-hole-hedgehog have given a global monopole and this monopole has been "swallowed" by the black-hole with core mass $M_{BH}\approx 3.65\times 10^{18}$ GeV and radius $\delta \approx 6\times 10^{-21}$ GeV$^{-1}$. The horizon radius of the black-hole-hedgehog is around $r_h\approx 1.14 \delta$.
