Re: Help needed recovering old wallet from bitcoin qt (around 2016)

Code:

walletpassphrase yourwalletpassword 600

And then after that use this command below to dump the private key

Code:

dumpprivkey yourBTCaddress

I tried this before without success.
BT core throws this error

Code:

15:44:53
BerkeleyDatabase: Error -30974, can't open database wallet.dat (code -1)

and the db.log says corrupted db

Code:

B_ENV->log_flush: LSN of 1/116917 past current end-of-log of 1/38105
Database environment corrupt; the wrong log files may have been removed or incompatible database files imported from another environment
PANIC: DB_RUNRECOVERY: Fatal error, run database recovery
wallet.dat: unable to flush page: 24
PANIC: fatal region error detected; run recovery
PANIC: fatal region error detected; run recovery
PANIC: fatal region error detected; run recovery
...

I am working always with a copy of my backed up wallet, so I can't break anything.

But no idea how to fix the db issues...

If I need to extract the keys manually, is there a step by step guide somewhere?

Best regards and thanks for the help.
