i think problem is in RETU N2200. bcz RETU generate these regulated voltages...
like 1.5, 1.8, 2.8, 4.7V

I think your problem not retu because VRCP1 &VRCP2 is generated for network,if vcore=1.4,vcorea=1.4,vio=1.8,vddr_ape=1.8,vdram=1. 8,vrfc=1.8,vr1=2.5 are present then your problem not Retu not Tahvo,but flash,ram,rap3g.
But pay attention to vrfc=1.8 it make connection between Retu & rap3g.
