Titanium Backup has been updated to v5.5.1.1

  • Fixed bogus “insufficient free storage space” notification during scheduled/widget job. It mostly happened after upgrading TB, because SuperSU de-authorizes apps (by default) after upgrades.
  • Fixed FC when backing up Wi-Fi networks if one of them had no SSID defined.
  • Updated translations.
