The Bousfield-Kan (or unstable Adams) spectral sequence can be constructed for various homology theories such as Brown-Peterson homology theory BP, Johnson-Wilson theory E(n), or Morava E-theory En. For nice spaces the E2-term is given by Ext in a category of unstable comodules. We establish an unstable Morava change of rings isomorphism between ExtUΓB(B,M) and ExtUEn∗En/In(En∗/In,En∗⊗BP∗M) where (B,ΓB) denotes the Hopf Algebroid (v−1nBP∗/In,v−1nBP∗BP/In). We show that the latter groups can be interpreted as Ext in the category of continuous modules over the profinite monoid of endomorphisms of the Honda formal group law. By comparing this with the cohomology of the Morava stabilizer group we obtain an unstable Morava vanishing theorem when p−1∤n.
