Corrupted Litecoin Wallet.dat

[Cameltoemcgee]

wallet.dat was fine, have multiple copies of it. then i reinstalled windows, afterwards i copied the entire litecoin folder that i backed up before the windows reinstall back into %appdata% roaming, and installed the latest version  of litecoin-qt... now it thinks its corrupted

Additionally, found a thread that mentions how to fix corrupt wallets...

tried using https://github.com/gavinandresen/bitcointools fixwallet.py and it doesn't run properly

the error i get is: "Skipping tem of type minversion"

Running dbdump.py --wallet Comes up with "Skipping tem of type minversion" after showing all the keys and stuff, last few lines of output below.

Thanks bitpop,

Managed to dump the private keys and whatnot, so i know i haven't lost all my coins, but i'll be buggered if i can work out how to import all the dumped keys into a new wallet.dat that works...

pywallet spits out errors when i try

Cheers!

Try the debug window and manual rpc command

Hi Guys,

Gonna resurrect this one. I thought i had dumped the litecoin backup... apparently not though. tried importing a private key, and it spat out an error. running the dump command again i realised i was dumping an unencrypted bitcoin wallet! FAIL!

I tried using the below command to dump my "corrupted" litecoin wallet.dat

pywallet.py --dumpwallet --otherversion=48 --datadir=C:\litecoin > dump.txt

no go, i still have the version of the blockchain that i copied off before the reformat and install of windows along with multiple copies of the same wallet.dat but it spits out the following whether i try it in the current litecoin directory with a new blockchain and old copy of the wallet.dat, or the backup copy of the blockchain and wallet located in C:\litecoin.

ERROR:root:Couldn't open wallet.dat/main. Try quitting Bitcoin and running this
again.

I definitely don't have LTC or BTC running and permissions look fine on the folder... has anyone seen this before?

Its getting to the point now i'm willing to pay a decent reward if someone can help me get it back... .2 BTC or 10 LTC if i can get into my wallet!

After reading through the debug.log i found the following reference to  db.log

2014-01-13 12:27:12 init message: Verifying wallet...

the db.log file referenced shows the following...

to another without clearing the database LSNs, or by removing all of

Hopefully someone much smarter than i am has some idea of whats going on here.

For anyone that has been following this thread, I got my wallet back... luckily, google keeps file revisions on its google drive, i had a previous revision of the encrypted archive i back it up to up there.... replaced the wallet.dat with that and its all good.

If i didn't have it, my wallet would have been gone. done and dusted.

Don't make the same mistake as i did which was simply copying the wallet.dat whilst litecoin-qt was running!!!!

Phew!

thanks to those of you who tried to help me out!
