I am having trouble using a back up sync wallet.dat. I sent sync to my wallet and I was having trouble getting it connected so I had to delete it but saved the wallet.dat file. I was finally able to get the wallet to connect to the network and then tried to replace the wallet.dat file but it does not seem to be working. Does anyone know how to fix this?
if you have synced wallet you can try this command line key one by one until issue will be resolved (you must backup your "wallet.dat" before):
-rescan
-reindex
-salvagewallet
