Thanks. I think that the problem is resolved.
My tools were working fine, my brain wasn't.
Flash meta_clean, flash manmod, flash:
Code:
edl /w /psuper manmod.img
edl /w /psuper /s2048 odm.img
edl /w /psuper /s4096 product.img
edl /w /psuper /s1236368 system.img
edl /w /psuper /s7295944 system_ext.img
edl /w /psuper /s8239792 vendor.img
(You know you can just copy/paste that whole block in one fell swoop?)
It might even boot normally (if you wipe misc).
