1  Bitcoin / Bitcoin Technical Support / Re: Btcrecover error with Electrum wallet on: December 11, 2019, 03:57:18 AM
One of my thoughts was to try and see if there was any way to convert my electrum wallet.dat into another wallet (specifically one supported by btcrecover), and dump the wallet.dat from the new wallet into btcrecover. I have not had any luck so far.
That's not possible unless someone were to write a completely custom piece of code that was able to:
1. Decrypt the electrum wallet
2. Extract either the seed or private keys
3. Import those into the wallet format of another wallet

Given you don't have the password to the wallet file, you're going to fail at the first step of "decrypt the electrum wallet"... if you had the password, you wouldn't need to convert the wallet file.

My other thought was to see if there was any way to write custom unisource code to fit the parameters of the unsupported wallet. Again i am very new to all of this so i apologize. There is almost $1400 on this wallet, so I am really hoping to get into it. I have already contacted dave several times and he has not responded.
You could try logging an issue on the btcrecover github issue register as Abdussamad suggested, but the original developer isn't very active these days (last commit was 22 Dec 2017 Shocked Shocked Shocked)




SOLVED
I opened the wallet in notepad and changed the seed version to 11, presto! Got btc to work!
or just try editing the btcrecover code and changing the btcrpass.py file... https://github.com/gurnec/btcrecover/blob/master/btcrecover/btcrpass.py#L1630

So, on the copy of btcrpass.py that is on your computer, find the code that looks like this:
Quote
       if wallet.get("seed_version") not in (11, 12, 13) and wallet_type != "imported":  # all 2.x versions as of Oct 2016
            raise NotImplementedError("Unsupported Electrum2 seed version " + unicode(seed_version))

And just add "18" to the list of seed_versions and see what it does... like this:
Quote
       if wallet.get("seed_version") not in (11, 12, 13, 18) and wallet_type != "imported":  # all 2.x versions as of Oct 2016
            raise NotImplementedError("Unsupported Electrum2 seed version " + unicode(seed_version))

I haven't tested this, so no idea if it will work or if it will blow up your computer! Tongue


NOTE: you should be working on a copy of your wallet file... not the original!!
2  Bitcoin / Bitcoin Technical Support / Btcrecover error with Electrum wallet[SOLVED] on: December 09, 2019, 07:31:53 PM
So I have recently been attempting to crack the lost password on my Electrum (seed version 18) wallet.dat. The seed and the password were lost about 3 years ago, But i recently came into possession of the wallet data. Now I installed all the proper programs.

(python 2.7/pycrypto/scrypt/google protocol buffers/Windows GPU acceleration for Bitcoin Unlimited)

when i run the cmd line C:\Users\****\Desktop\coins\btcrecover\btcrecover-master>python btcrecover.py --wallet wallet.dat --token token.txt

I receive this error on response

"NotImplementedError("Unsupported Electrum2 seed version " + unicode(seed_version))
NotImplementedError: Unsupported Electrum2 seed version 18
"

Now im assuming that just means my wallet type is unsoported. Im slightly new to a lot of this stuff so I'm not 100% on where to go from here.

One of my thoughts was to try and see if there was any way to convert my electrum wallet.dat into another wallet (specifically one supported by btcrecover), and dump the wallet.dat from the new wallet into btcrecover. I have not had any luck so far.

My other thought was to see if there was any way to write custom unisource code to fit the parameters of the unsupported wallet. Again i am very new to all of this so i apologize. There is almost $1400 on this wallet, so I am really hoping to get into it. I have already contacted dave several times and he has not responded.

If someone is able to help me figure out btcrecover I would be more than happy to share some of my coin.

Here is a screenshot of the error

Thank you!

EDIT;
I fixedthe issue and got btcrecover to work on electrum2 wallet. Simply drag and drop the wallet.dat file into notepad, ctrl+f "seed_version" change whatever your seed version is to 11. Presto!

-snip-
I did, wallet.dat was unrecognized

Had the same issue, probably best to contact btchris, they wrote btcrecover.
On it, thanks for the advice!

So dave responded, he informed me that Electrum wallets are currently unsupported, and they hope to add support before the end of the month. I spent about 3-4 hours setting up btcrecover, but when i launch it on my pc the command screen immediately closes.
You have to use it through the command line. You cannot just double click the exe file.
I have a very large list of possible passwords and or phrases that may be contained within the password.

If Dave doesn't respond, you can try recovering the password yourself with btcrecover, however it will be more difficult and involves a bunch of reading to get it set up and running...

The wallet had a rather unusual format, I did some testing with your software and it did not recognize the wallet format. Maybe the OP can get in touch with you, Id rather not share the data I copied here without their consent.

I did, wallet.dat was unrecognized

I can send links with the original wallet.dat

No there is no flag that appears so the seed must still be there.
My password is no longer than 15 characters.
And is more than likely either 8 or 10.
I have a very large list of possible passwords and or phrases that may be contained within the password.
I am 90% sure that these phrases I have will contain the password.
If not, and I did make a unique password, it will be no longer than 8 characters (very very unlikely it's unique)

Thank yiu for notifying me.
I have removed the wallet data.
I have already sent Dave an email at wallet services.
So far no reply, but thanks for the tip!

Looking for somebody who knows how to run brute force scripts, I created a wallet 1 year ago, and have since lost the seed and password.
I recently re installed Electrum onto my PC and the program loaded into my old sead by default, i hadnt noticed this until after I purchased 0.19 Btc and had them deposited into my wallet. I no longer remember this password and did ot store the seed. If anybody can break in, I would be happy to share 0.09!
