I just recently discovered that i had a GUIminer that i installed in 2012. I also had Bitcoin Core with several wallet.dat files. I have been unsuccessful in running a full node as my computer and connection are slow. Two of the wallets i cant dumpwallet because the passphrase is incorrect. I was able to dumpwallet one of them and there are 25k+ addresses. Most Change=1, Script=1 all with the private keys. I uploaded the master key and have checked many addresses but the all say zero. I have a watch only address with 18btc that i cannot unlock.
Ive tried pywallet for andriod but run into bin/sh error In python. Ive tried it all. Really need some help finding these balances.
