Let F/Q be a CM field where p splits completely and r¯:Gal(Q¯/F)→GL3(F¯p) a continuous modular Galois representation. Assume that r¯ is non‐ordinary and non‐split reducible (niveau 2) at a place w above p . We show that the isomorphism class of r¯|Gal(F¯w/Fw) is determined by the GL3(Fw) ‐action on the space of mod p algebraic automorphic forms using the refined Hecke action of Herzig, Le and Morra [Compos. Math. 153 (2017) 2215–2286]. We also give a nearly optimal weight elimination result for niveau 2 Galois representations compatible with the explicit conjectures of Gee, Herzig and Savitt [J. Eur. Math. Soc., to appear] and Herzig [Duke Math. J. 149 (2009) 37–116]. Moreover, we prove the modularity of certain Serre weights, in particular, when the Fontaine–Laffaille invariant takes special value ∞ , our methods establish the modularity of a certain shadow weight.
