4. Download presynced blockchain and unzip to this folder https://github.com/numuscrypto/numuscore/releases/download/1.0.1.3/num_db_250151.zip
5. Start your updated wallet and wait for full synchronization
6. After full resync you need to correct your wallet file balance , to make it open Help -> Debug Window -> Console and put repairwallet command to the console.
