Thanks for the links, I'm going to study it.

But I still don't know where to copy the backup file to my computer :-(



So change - I succeeded.
I am now in this chapter:

RECOVERING FROM PROTOBUF WALLET FORMAT

But something is wrong:

kamiil@vitasekk10:~$ cd bitcoinj/tools
kamiil@vitasekk10:~/bitcoinj/tools$ ./wallet-tool
./wallet-tool: line 19: gradle: command not found
kamiil@vitasekk10:~/bitcoinj/tools$ ./wallet-tool reset --wallet=/tmp/bitcoin-wallet-decrypted-backup
./wallet-tool: line 19: gradle: command not found
kamiil@vitasekk10:~/bitcoinj/tools$

How are you getting on with using Ubuntu?

I followed the instructions - I installed Ubuntu from the Windows Store.
But I still don't know where to copy the backup file to my computer :-(



kamiil@vitasekk10:~$ openssl enc -d -aes-256-cbc -md md5 -a -in bitcoin-wallet-backup-2014-08-18 > bitcoin-wallet-decrypted-backup

If there are no transactions: any chance you have the wrong backup?



I hope I have the right backup.
If I make a backup before buying bitcoins, do I always need to make a new backup?

In your wallet, try going to Options (three small dots at the top right) and click on "Request to legacy address". Then hit the share button and look at the address which pops up. Does this match any of your old addresses?

When I do this twice in a row, the old address is always different.

First:
113EEBvAoP16AZtmsL6UjUdtvCxY8xdNYM
Second time:
18QRDZbjEbmPojspNqvEMsBpgmMxmwjwL6
Third:

What step you are now following? Is that the "RECOVERING FROM BASE58 KEY FORMAT" or "RECOVERING FROM PROTOBUF WALLET FORMAT" or are you still decrypting the wallet?

Still decrypting the wallet. I don't know where to upload the backup file. I have Windows (C: \ ..) and installed Ubuntu on Windows. I'm sorry, I'm an amateur in Linux.


Anyway I found an old guide and maybe it can help you [HOW-TO] Export seed and private keys from your Bitcoin Wallet for Android


Thank you, I'll look into it

Does the new address in the restored wallet being with "1", or with something else ("3" or "bc1")?

The new address is "bc1qve5gf6juven........"

That is OpenSSL encrypted Base64 data. The initial string U2FsdGVkX1 decodes to "Salted_". This is normal for a backup from Schildbach's Bitcoin Wallet.

When you open the wallet file with your Bitcoin Wallet app, are you prompted for your password? Do you get an option to choose an address type or derivation path?

Yes, I am prompted for a password. I know the password. Nothing more to choose from.

/path/to/wallet/bitcoin-wallet-backup-2014-08-18

But where should I copy the file to disk if I have Windows with Ubuntu installed?
By the way - thank you for your willingness!

I am not an expert in Bitcoin Wallet (for android), but it is possible that something has changed during 7 years, it would be necessary to check release notes.
Maybe they by default work now on (Native)Segwit, not on old 1xxxx format? No idea.
Did you protect wallet with PIN?

Anyway, they say you may manually restore private keys from backup file (scroll to the bottom):
https://github.com/bitcoin-wallet/bitcoin-wallet/blob/master/wallet/README.recover.md
You may try to use their tool (preferably being offline).

As you receive WIF, you may probably easily import it to any other client, mobile or desktop.


Thank you, I tried it according to the instructions, I got to the DECRYPTING paragraph.
I have Windows, I have installed Ubuntu, but I do not know how to enter the path to the file in the command line :-(

What happens when you restore the wallet? When you say "you don't see anything", do you mean the app can't find the wallet file to restore it, it finds it but won't restore at all, or it does restore but shows you an empty wallet? If it doesn't restore at all, does it give you an error message? If it does restore, do the addresses in the wallet match the addresses you have above? Do they begin with "1" or do they begin with something else?

If you are going to go down the route of dumping your raw private keys, then you should preferably be doing this on an offline computer for security reasons.


Now I've renewed my wallet. I waited a long time for 60 months to load.
Now I see mBTC 0.00 - so the wallet is empty.
No error message.

The wallet address is different and there is a comment that this address will change after each transaction for security reasons.

In the first post I wrote incorrectly what my backup file "bitcoin-wallet-backup-2014-08-18" contains

It correctly contains the following:
U2FsdGVkX1809I / daCCv4Qor7gyUZNvp00Z3Z5TMpJKSRpvDVs1wxikwES5UiKeU0Z4R ....



and many other characters

Thank you.
Yes, I secured my wallet with a password. I know the password.

Hi.
Let me ask you a question.
I set up my wallet in 2014, I think it was Bitcoin Wallet software from Google Play.
I bought a 0.05 BTC.
I made a backup (bitcoin-wallet-backup-2014-08-18)
The address is 1MV2No1t2VAyoKhXAKNzGFyZmcXiNfjdB3.

Unfortunately, when I restore this backup in the new version of Bitcoin Wallet software, I don't see anything there.

Is there any way to get back to my bitcoins?

The file "bitcoin-wallet-backup-2014-08-18" contains a number of characters:

1MV2No1t2VAyoKiXAKNzGFyZmcXiNfjdB3
149cen8AKLfWrfhpWS5cHnBFZLkfXSDZoK
13bCDmpKyccq8fx8ZTnsDSBrjs2MLcCQ98


(I intentionally changed a few characters so that it would not be misused)

Thank you very much for any advice
Kamil
