| May 23, 2012 at 6:20 | comment | added | ingorichter | Yes, I'm currently extracting everything from BackupManagerService to read the contents of the backup file. It's a good amount of work, but I need my data back... | |

Since you know the password, you can derive the key and decrypt the data. So it's still doable, but not particularly easy... | |
