Hey everyone!
I just deleted wallet.dat file from PC. And recovered several old wallet.dat files. I'm trying to dump/access by pywallet by --dumpwallet and --recover (i already install pip, twisted, zope, bsddb). Useless unfotunately.
If i use --dumpwallet (code: python --passphrase='pass' --otherversion=48 [LTC wallet] --datadir=C:\pathtowallet --dumpwallet), everytime i get error:
ERROR:root:Couldn't open wallet.dat/main. Try quitting Bitcoin and running this
again.
The error you are getting (Couldn't open wallet.dat/main) indicates that PyWallet is unable to parse your "wallet.dat" file as a wallet file. It's possible the file is corrupted beyond PyWallet's ability to simply read/parse it as a wallet.dat file. This is not uncommon in the case of recovered files that may have had parts of them overwritten.I just deleted wallet.dat file from PC. And recovered several old wallet.dat files.

If i use --recover (code: python --recover --recov_device=C:\Path\wallet.dat --otherversion=48 --recov_size 10Gio --passphrase='pass' --recov_outputdir C:\Path\foundkeys):

Again, it seems like the wallet.dat file you are attempting to recover is damaged beyond PyWallets ability to recover the keys from it. I've run this on a known "good" wallet.dat and get:Read 0.0 Go in 0.0 minutes

If I try and damage the file (deleted last half of the file), it still works... even randomly replacing large chunks of data with random text still works:

Note how the number of possible encrypted keys is different (looks like I deleted a few!
)... I was even able to delete the file and PyWallet was still able to "recover" it from the usb stick:Code:

So, if it isn't working, then either your recovered "wallet.dat" isn't actually a wallet.dat or it is really corrupted.
Also, how "new" were the wallet.dat files? Pywallet can sometimes have issues with newer wallets due to wallet file format updates in more recent versions of "Core".
