This wallet I just restored has no transactions any earlier than maybe block 800k. Well, I told the wallet to refresh from 80k by accident. It's taking forever to scan. I don't want to just let the computer refresh forever. Is the 80k located in some config file that I can edit? Or is there a command I can enter to tell it to start at 800k?
The most straightforward (and probably convenient) way is to, like user36303 said, exit the wallet and restart the process with the correct blockheight. There is currently no command to alter the restore blockheight after you have already entered it. Furthermore, I personally don't think it would be worth to implement such a thing, because the reward is not worth the amount of work that has to be put into it.
