[Android Q&A, Help & Troubleshooting] mmortal03:
On these backups, after running "perl backupdecrypt.pl --nocompress backup.ab test.tar",

I then run "perl tarfix.pl test.tar | tar xv", and I get a bunch of garbage as output (see below). I've tested this both on Windows and on Linux, with the same result, so it isn't a platform issue. I'd post over in the applicable tarfix.pl thread, but I don't have 10 posts yet to be able to do so.
