The same works for Nexus 7, but there is a difference, the lockscreen.password_salt is not located in /data/data/com.android.providers.settings/databases/settings.db, but rather in /data/system/locksettings.db, table is locksettings.
P.S correction, Nexus 7 works the old way (just salted sha1/md5) so indeed that's Samsung-specific. Apparently I had bug in my script to validate the algo.
