comment Is there a way to look inside and modify an adb backup created file?
I'll give it a try. Thanks for the further investigation on this. I'll let you know the outcome of my exercise.

The error that I got during restore was different. There was always the issue restoring the contacts database. Hm, if the archive is now corrupted, do you know a good way to repair it? I know that this sounds silly, but I'm moving away from my original issue. Now there is a way to examine the contents of the backup but I'm still unable to restore the backup. I'll see if I can find a good zip repair. Thanks for giving it a try on your Nexus collection.

I created it with my Galaxy Nexus which runs 4.0.4.

Thanks Nikolay! I took your source and tried it with my backup file. Luckily it shows the same misbehavior like my implementation: both implementations are unable to read the backup file and create the plain tar file. The error that I get is java.util.zip.ZipException: invalid stored block lengths. Now I need to find way around this issue.

Since I'm not a crypto expert, it took some time until I figured out what was missing. Yes, I took the BouncyCastle provider and the PBKDF2WithHmacSHA1 SecretKeyFactory that Google provided as a patch to the BouncyCastle implementation. Now I'm able to decrypt the file, but I haven't yet started to extract something from the backup.

Wow, I'm impressed with your analysis. I extracted some code from BackupManagerService into a simple groovy script, but when I run the program the result is always the same: wrong password entered! I created a new backup with a simple password, but the password verification failed again. Currently I try to follow the program as described above to find my mistake.

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...

Thanks! That's at least a starting point to look inside the file. Would have been easier if I hadn't provided a password for the backup.
