Old blockchain.info wallet from 2014 and before -16,17,19 words precovery phrase

[pizzdaniel]

In 2013 and 2014 I had some blockchain.info wallet ... In time I lost emails and identifier, I totally forgot about. Recently I fund the mnemonic, aka seed aka recovery phrase. Wowww I was very happy. But my happy was not for long. The recovery phrases are NOT standard long, like 12 or 24 words, the phrase contain 16, 17 and 19 words + this words are NOT in the BIP39 wordlist.

blockchain info support not answer to my help request. I read on internet, reddit, bitcointalk, etc - that blockchain before 2014 used totally other wordlist (not the standard bip39 wordlist) and script to create this mnemonic (seed)

any help and ideea would be appreciated how can I restore the btc address and private key from this old blockchain info's non standar bip39 wordlist ?

thanks for reading

Have you accidentally visited and tried this page of blockchain for its legacy wallet recovery https://login.blockchain.com/wallet/forgot-password. I'm sure it would help.

[edit] Seems you have a weird numbers there, can you tell us if what is the numbers of your recovery seed exactly?

Invalid Checksum whats blockchain info recovery say when i inter my old recovery phrase

Would you answer my edited post above?

can you tell us if what is the number of your recovery seed exactly?

Have you tried to double check the spelling of the words as well? You might put some misspelled words.

[pizzdaniel]

yes, have 5 seed, because all my brother had his blockchain account
seed contains as i said 16,17,19 words

I doubt that seed that was generated for the blockchain.info's wallet back in the day was the standardized seed. It was more like a random set of words generated that uniquely identified a wallet's private key and not directly associated with it. Support is still your best bet. How many bitcoins are we talking here anyway?

[pizzdaniel]

support dont respond ... i think we had 4-5 btc for sure

[Potato Chips]

Patatas is right, what you need is their aes.json file as the keys lie there.

If found, import them here: https://login.blockchain.com/wallet/import-wallet
Then the recovery phrase comes into play if you don't know the password. You can use the link on the first post for that, but I see that there was an error??? errr... hmmm I guess let's worry about it after you find the files.

16, 17 or 19 words can't be a SEED unless the excess words are customized extensions like Electrum implemented.
But still, you said that "these words" aren't belong to BIP39 word list (really, all of them?); It's not a SEED then.

There's only one Bitcoin-related wallet generator I know (address & private key pair) that can make use of any word and any number of words: Brainwallet.
It's pretty popular during that time, you might have created a brainwallet and imported the private key/address to blockchain.info before.

Does Brainwallet ring a bell?

afaik that phrase can be used only to recover forgotten password, and you will still need to remember wallet identifier
but you said it returns "Invalid Checksum", so perhaps you mistyped or lost one of the words?
btw... is this the mnemonic you get when creating the account or the address?
I asked, because my note shows there are 2 different phrases for my old blockchain account,
one for wallet recovery and another for paper wallet I created there

it's not a seed phrase, they called it as "Wallet Recovery Mnemonic" to work specifically only on blockchain site
this random length mnemonic exist for wallet created before HD wallet becomes standard wallet on the site

do u know how do you recover the paper wallet with just the 12 words? is it the same as recovering a blockchain. com wallet?

That's the same link OP mentioned in the first post and it didn't worked, he said it returned with "invalid checksum".

Then one or more words are wrongly written down. there areabout 50000 words for each to change.

we have written a brute forcer for it. if you still need help then pls reach out.

I have long had a couple of abandoned wallets that were opened on blockchain.info in 2014.  Then, before them, the devs of this wallet came up with a seed phrase consisting of 16, 17, 19 words.  In my case it is 17 words.  I decided to try to restore access to these old accounts, although there is very little on them, maybe only ~ 1000 - 2000. sat.   But I was just wondering if I could get access to them and find out the real seed phrase to these 12-word in mainet accounts.  I used a service to find the wallet number and password, which is discussed above in this thread.  But I don’t remember, it seems like I didn’t report any of my email to blockchain.info at that time.  I don't remember at all?  But even if I sent them an email address, it was still lost.  So, on this specified service, I reset 2FA and entered a new email in the appropriate column, to which I naturally have access.  Then I received a notification that the recovery process had started.  And another message that the recovery process can last up to 2 weeks.  

Actually why am I writing in this thread.  I'm running an experiment and will report here how this recovery system in blockchain.info works.  How does support work and will I need to contact support again or several times.  Will support respond and what will they say?  And will I eventually be able to restore access to this custodial wallet?  I did all this yesterday.  So far there has been no response from blockchain.info.  When I enter my wallet number and password, it says that I need confirmation by email (to which I do not have access).  So far it's a vicious circle.

I doubt if support will help you out to recover the account
Having access to the original email would be much helpful, as you would just search up messages from Blockchain.info. That's what I did back then, even when I had forgotten my wallet ID, and it was right there in my inbox.

If changing an email address was that easy without access to the original email, just imagine how many people's accounts would get hacked. That right there would be a serious security loopehole.

It appears blockchain.com can at least tell you the registered email address in your account? so keep pushing onto that  

Remembering the creating date is now important as the support told me they can help me and will send me my old emailadress
if i prove that the wallet id is by me by naming the date or the wallet creating date.

I wonder if you have the json file (wallet backup file) with you? From what I saw, blockchain.com barely provides help when it comes to legacy accounts so if you don't have that, your chances are much more slimmer than before. They also advertise the wallet as non-custodial so I guess they can take a "we're only a software provider" stance or something similar.

So, on this specified service, I reset 2FA and entered a new email in the appropriate column, to which I naturally have access.  Then I received a notification that the recovery process had started.  And another message that the recovery process can last up to 2 weeks.  

Sorry it wasn't clear to me but what was the specified service? keychainX? or this--https://login.blockchain.com/wallet/forgot-password?

He's talking about their 2FA Reset form, here: https://login.blockchain.com/en/#/reset-2fa
After filling-up the form, it will show the user this message:

So, on this specified service, I reset 2FA and entered a new email in the appropriate column, to which I naturally have access.  Then I received a notification that the recovery process had started.  And another message that the recovery process can last up to 2 weeks.  

Unfortunately, it's requesting for the associated email and not any other email address.

And their Email Authentication isn't their 2FA service so the reset 2fa page isn't going to do anything for your account.
It's only a mandatory authentication whenever you login using a new IP address, all their users has to do that to log-in (so much for being a non-custodial wallet)

Of course I don't  .json.  Apparently it would be easier with this file.

Yeah, https://login.blockchain.com/wallet/forgot-password

Yeah!  You wrote everything correctly.  
It was through this link that I reset the 2FA authentication.  
However, of course, I do not have access to the old email that was used during registration.  
All I have is a 17 word passphrase and I know exactly when the wallet was created.  On the other hand, a cryptocurrency wallet service provider such as blockchain.info or Blockchain.com must develop rules of action in case the owner of the wallet loses access to the email from which he would have been registered.  This is a fairly common everyday situation.  

So I'm trying to figure out how to restore access to this custodial wallet using devs Blockchain.com.  I wrote in a letter to support the wallet id and the exact date of its creation.  And I wrote to them that I had 17 words of a passphrase "seed"?.
By the way, the service you specified from Blockchain.com allows you, knowing 17 words, to recover both the wallet id and password for logging into the wallet.  

I haven't received a response from support yet.  
But I will continue the experiment and report the results here in this thread.
