I don't recommend downgrading firmware, that shouldn't be needed. I'd have thought that if there were an issue with resync on 4.2.31 we'd have seen many posts on that here by now.
The OP already followed the rest of your advice, so I think the next step is to test the new disk (since it might simply have failed).
