It seems that I have 2 user ID: My error. Will keep this one.
Trying to use the information I got so far.
In this order:
Create a new "Virgin" bitcoin instance.
Disable Pruning
Run a full update.
Try a dumpwallet import.
Is this recommended procedure.?
I wonder what the real purpose for creating a dumpfile is. It clears the wallet so what can you use a dumpfile for (except import).
it would be nice to have a possibility to recreate a wallet.
Maybe someone has already created a useful tool that uses a dumpfile as input? Except "importwallet"
