Title: Upgrading to Bitcoin Core 0.16 Post by: Bacchusm on May 02, 2018, 10:33:23 PM I used to use a old Bitcoin Core and it crash. I kept the wallet.dat file. It is only 88 Bytes.
So I d/l the new Bitcoin Core 0.16.0 and when I try to replace the wallet.bat in .16 it crash with file: wallet/wallet.cpp, Line 550 Expression: copyFrom && "Oldest wallet transaction in range assumed to have been found." then it says 'Abort', retry ignore. Any help would be appreciated. 1. Ignore crash the programs 2. Retry 'this Application has requested the Runtime to Terminate it in an unusual way' Contact support. Thank Bacchusm Title: Re: Upgrading to Bitcoin Core 0.16 Post by: achow101 on May 03, 2018, 03:08:55 AM I used to use a old Bitcoin Core and it crash. I kept the wallet.dat file. It is only 88 Bytes. Your wallet.dat file is most definitely corrupt and does not contain any key data if it is only 88 bytes. An individual key is much longer than 88 bytes. The keys don't even exist in this file so there really isn't anything for you to even attempt to recover.Title: Re: Upgrading to Bitcoin Core 0.16 Post by: Bacchusm on May 03, 2018, 07:17:33 AM I used to use a old Bitcoin Core and it crash.

I guess the correct size would be around ~200kb.
You might try out pywallet (https://github.com/jackjack-jj/pywallet). Even tho it is no longer maintained it still works pretty well with old wallet files. Pywallet will try to dump all private keys inside your wallet.dat.

Pywallet will try to dump all private keys inside your wallet.dat. I tried pywallet and didn't get it working, when trying to figure it out I came across this : wallet-key-tool. that had a good GUI, so I dumped my wallet.dat , and I can export it to MultiBit.key, multibit.Wallet or bitcoin-core Dumpwallet.txt I have exported it to all three. I like using Bitcoin-Core. How can I import any of these to it. Thanks Again!

Open bitcoin core Go to Help -> Debug -> Console Unlock your wallet.dat (if there's a passphrase) Code: walletpassphrase passphrase 600 Then Code: importprivkey "5Privatekey" Title: Re: Upgrading to Bitcoin Core 0.16 Post by: Bacchusm on May 04, 2018, 07:58:22 PM How can I import any of these to it.

Title: Re: Upgrading to Bitcoin Core 0.16 Post by: HCP on May 05, 2018, 08:29:11 AM Start at top or bottom of the list, it isn't that important... the import thing if you're going to import multiple keys at once, is to use the "false" parameter after every importprivkey command except the last one... like this:
Code: importprivkey "KpriVatEyKeyNumBer1" "" false Adding the false parameter stops Bitcoin Core from automatically rescanning the blockchain for transactions related to the newly imported key... this can take quite a few minutes (if not hours) to complete, so you only want to do it after you've imported the last key... otherwise you'll have the long wait after EVERY importprivkey! |
