Salvaging a broken wallet.dat with 3M leafs!!Ok, I had done something wrong and I broke my original wallet.dat, and original leafcoin-qt client would not salvage it. So after a bit of googling I tried pywallet[1] and after a bit of experimentation I came up with the following solution and it worked!!
1. Copy the broken wallet.dat onto a usb stick or sd card or whatever you like (but not an encrypted filesystem!), in my case, it's on a 8GB USB stick on /dev/sdc1.
2. As root type:
# ./pywallet.py --recover --recov_device=/dev/sdc --recov_size 8Gio --recov_outputdir=.
Enter the passphrase for the wallet that will contain all the recovered keys: <passphrase in the new recovered key>
Enter the possible passphrases used in your deleted wallets.
Don't forget that more passphrases = more time to test the possibilities.
Write one passphrase per line and end with an empty line.
Possible passphrase: <passphrase in the old broken key>
Possible passphrase:
Starting recovery.

The new wallet ./recovered_wallet_1390767057.dat contains the 201 recovered keys
This *should* work and keep all your lost coins!
3. Change ownership of the recovered_wallet_*.dat file and copy it into your ~/.leafcoin/wallet.dat (
MAKE A BACKUP COPY OF THE EXISTING ONE IF YOU HAVE ONE).
# chown <user> recovered_wallet_*.dat
# su - <user>
$ cp ./recovered_wallet_1390767057.dat /home/<user>/.leafcoin/
Now as the user:
$ cd .leafcoin/
$ cp wallet.dat wallet.dat.bak
$ cp ./recovered_wallet_1390767057.dat wallet.dat
$ leafcoin --salvagewallet
(Note: I'm using leafcoin in the leafcoin-qt Debian package that I made public, otherwise, leafcoin-qt should work).
Voila! leafcoin scans the wallet again and displays 3M Leafs as available again!
4. Now all I have to do is send them over to my new wallet (for some reason it doesn't accept the passphrase I gave it above, but I hope to figure this out soon, good news is that I didn't lose 0.3 BTC worth of Leafs
