My Surface Pro 3 died last October which had my bitcoin wallet on it. I forgot that I had any. I had bought them a (long) time ago for about 10 euro if I remember it correctly. But since the hardware crash of my sp3, the rate went up. Way up….

I decided to look into my backup and try to restore my wallet to see how much I had and how much it’s worth today. I had multibit classic in the beginning and upgraded to multibit HD 0.5.x back then. During the move from classic to HD I forgot my wallet words and only had my password and the backup AES wallet files.

I started my first recovery attempt on may 30th, but failed because I had no wallet words.

My second try was last week as I found this GitHub repo with a python script which can extract words from a backup file if you have the password. Sort of brute force “attack”. https://github.com/gurnec/decrypt_bitcoinj_seed

So I installed python 2.7.x alongside with 3.6 which I already had. and ran the PowerShell script.

I had a Windows 7 style backup by the way of my Win10 device and had to navigate to “C:\Users\myUsername\AppData\Roaming\MultiBitHD” and restored the full content of that folder to a new folder on my desktop. Please do not forget to check the box to have the original folders restored. Otherwise it will replace files with the same name and path references will be broken.

But somewhere in the mutlibithd is the rolling backup which you can restore once you have your password and wallet words…. so I thought.

But the amount stayed unconfirmed. So it’s useless. I have seen a lot of people with this exact same issue. Some moved away from multibitHD just because of this. The solution was not that obvious. It also did not work for everyone.

I had to downgrade to MultiBit HD 0.1.1 https://multibit.org/releases/multibit-hd/multibit-hd-0.1.1/

and renamed “C:\Users\myUsername\AppData\Roaming\MultiBitHD” to “C:\Users\myUsername\AppData\Roaming\MultiBitHD-old” and re-restored the wallet with the password, wallet words and backup file.

It is weird to have the old 0.1 version, but I am glad that it is confirmed again and in my wallet. Now I can step away to alternative wallets.


Good luck!
