Ledger Nano, one lost word of the 24

[Kelman]

Hi all,
I have a problem :
- I resetted my Ledger Nano S by putting 3 times the wrong password.
- I do have the list of word, and have 23 of the 24 words (yes this is weird but that's the problem).

So I know 23 of the 24 words, but I'm stuck to know what the last word is, and I'm not really sure about its position in the whole list...

Does someone have a solution for this?

Thanks,
kel

You'd want to explore this[1]. It's not a huge issue as long as its only one word. You should run it on an offline computer as far and possible and assume the seed to be compromised once you've found the correct word and transfer the funds into a newly resetted Ledger wallet, with the seed correctly written down of course.


[1] https://github.com/gurnec/btcrecover Oof I linked the wrong one. See below.

-snip-

That particular GitHub has not been updated in over 3 years. There is an active development fork of that software available here: https://github.com/3rdIteration/btcrecover/. It provides more features, more wallet support, and is optimized to run faster. It also has more thorough instructions and guides for users who might not be entirely sure what they are doing.

Here are the instructions you want to run the seedrecover.py part of that software: https://github.com/3rdIteration/btcrecover/blob/master/docs/Seedrecover_Quick_Start_Guide.md

You will need ideally the master public key from your wallet, or if you don't have that, then one of the first used addresses on that wallet. Download and run offline, follow the instructions, supply your xpub or address, supply your 23 words (in order), and let it run.

If that's all too complicated, than an easier method may be to use this: The FinderOuter, a bitcoin recovery tool (v0.5.0 2020-09-17)

I don't think it supports the case where you do not know which location your word is missing from, but with only 24 possibilities you can just run it 24 times until you find the correct one.

[bob123]

As long as you are sure that the order of the 23 words is correct, you are fine.
btcrecover is what you are looking for to bruteforce your mnemonic code.

If you need help getting btcrecover to properly run, feel free to ask. But do not reply to PM's asking for your mnemonic.

Hi guys,
Thanks for your quick answers.

I'm not a computer expert but understand what I need to do. I had found the first version of BTCrecover and managed to run it on MacOs,itbut did not help me get the missing word.

I tried to install the latest version, with python 3.9 but the "installations" procedure lacks a few things...
I'm actually experiencing this issue :

When I try do insert this command.
pip3 install -r requirements.txt

It tells me : ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'

So I can not continue with it, do you know how to do it?

The commands that I find here seem to not work correctly : https://github.com/3rdIteration/btcrecover/blob/master/docs/INSTALL.md
Is it because I installed python 2.7 before so it the 3.9 is not used by default? when I type "python3" in my terminal, it says it is not found...

If you could help me it would be great!

[ranochigo]

When I try do insert this command.
pip3 install -r requirements.txt

It tells me : ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'

So I can not continue with it, do you know how to do it?

Shouldn't be the case, you're specifying pip3 as the package installer.

I think this is an obvious question but, are you in the correct directory? Is the requirements.txt inside your directory?

[Kelman]

Hi, I think like you said that the repertory was wrong.
Now I tried to install it and it says the following (huge) error message :

Do you know what could be done?

[HCP]

what happens if you just use the command:

Code:

pip3 install coincurve

Do you get the same error?

If that's all too complicated, than an easier method may be to use this: The FinderOuter, a bitcoin recovery tool (v0.5.0 2020-09-17)

I don't think it supports the case where you do not know which location your word is missing from, but with only 24 possibilities you can just run it 24 times until you find the correct one.

It does not support it yet, since I'm still working on issue #9 haven't been able to add any new features.
Recovery is quite fast though (~1 second for 1 missing word), the whole thing (2048 * 24) shouldn't take more than 10 seconds if the path is hardened which I believe it is for Ledger Nano.

Hi all,
I have a problem :
- I resetted my Ledger Nano S by putting 3 times the wrong password.
- I do have the list of word, and have 23 of the 24 words (yes this is weird but that's the problem).

So I know 23 of the 24 words, but I'm stuck to know what the last word is, and I'm not really sure about its position in the whole list...

Does someone have a solution for this?

Thanks,
kel

Btcrecover can do this but you have to know at least one of your addresses on your ledger that was previously used.

It also has some compilation errors with Python3 so you could also try with python2.7 which is much more stable.

There are 3 main branches of btcrecover that works differently. 1 for python2.7 one for python3 and one which is modified for segwit.

So depending on your computer setup and target address you should choose accordingly.

if you need a visual guide you can view a video of this guy, it gives a pretty good step by step if you are stuck

It does not look to be difficult, as long as you are sure of the order of the rest of the words.
I may prepare a simple program which may check it, but you will need to know 'derivation path' (account number?) and address used (preferably the first one).

And here you are:
https://github.com/PawelGorny/lostword
Requires java of course.
Very simple program, could be improved in many ways, but not today Slow, but works. If your case is simple, it will help, if not - let me know, I will modify it.
I have tested with examples from https://iancoleman.io/bip39/, using first address from derivation path m/0/0.
Here you may download compiled .jar, or if you do not trust me, you may download sources and compile on your computer.

Hello everyone,
Thanks for your kind answers.

I tried several options and finally managed to make it work with BTC recover.
The actual issue was that the script of BTCrecover is not encoded for Mac OS, so this needed a few adjustments to make it work.

@PawGo : Your option was easier to use, but unfortunately did not find my missing word, I don't know why.

Thanks again and have a great day,
Kel

The actual issue was that the script of BTCrecover is not encoded for Mac OS, so this needed a few adjustments to make it work.

Any chance you could be a bit more specific as to what was needed to make btcrecover work? It's a Python script, and Python is cross-platform, so the script shouldn't really have needed any mods to be "MacOS" compatible.

Unless it was just that the version of Python that is included in MacOS is incompatible with btcrecover? For instance, there were "breaking" changes made to Python v3 that can cause issues with scripts designed for Python v2
