I recently found two old backup files from an Android Mycelium backup (~2013) which contain a non-trivial amount of bitcoin.
The trouble is that I no longer can find the 15 character password/checksum character associated with the private key that is being requested when I scan the private key into Mycelium.
What are my options? 15 characters should be brute forceable, right? Any advice much appreciated.
