IIB compactifications enjoy the possibility to break GUT groups via fluxes without giving mass hypercharge gauge field. Although this important advantage has greatly motivated F-theory constructions, no such have been constructed directly in terms of M-theory G 4-form. In note, we give a general prescription for constructing G-fluxes. By using stable version Sen's weak coupling limit, verify their connection with fluxes. We illustrate lift number examples, including compact SU(5) × U(1) model explicit realization doublet-triplet splitting. Finally, prove an equivalence conjectured earlier work as by-product.
