PreCentral: Use Save/Restore to backup additional system files and images (homebrew)

Save Restore Misc OS Backup filesThe WebOS Internals' homebrew app is great to in case you ever need to webOS Doctor you device, swap it out with a new device, or even transfer data between a phone and TouchPad. Typically, Save/Restore will save files that are tied to specific applications, such as progress in your games, specific stock quotes set up in a finance app, or settings/preferences for apps. However, there are a lot of other miscellanous files that you may find throughout webOS that are not tied to specific apps, but you would still like to save. These can include changes that you have made to the or , the background for the phone dialer, or even the database files that contain some system data (e.g. cookies.db, database.db). While you would never want to restore those database files after a device swap or webOS doctor, it would be nice to restore those personalized image files.

Since this is not your typical Save/Restore function and does involve some additional homebrew knowedge, it's not automatically added to the list of supported applications within the app. But, there a little easter egg within Save/Restore that will allow you to backup or restore these files as needed. The easiest way to accomplish this is to use Internalz Pro, by Jason Robatille, which is available in both Preware or webOS Quick Install.

  1. Open Internalz Pro
  2. Navigate to /media/cryptofs/apps/usr/palm/applications/org.webosinternals.saverestore/contrib
  3. Tap on the "org.webosinternals.deviceinfo" script and select "Copy". Find "/var/svc/org.webosinternals.saverestore", highlight it and then choose "Select" to copy it.
  4. Now, you can open up the Save/Restore app, wait for the data to load and choose "Save Application Data". Scroll down until you find "Misc OS Backup files" and ensure that it is toggled to "ON"
  5. Once you run that script, you will have all these files backed up to the USB drive on your webOS device. 
  • Be aware that when it comes time to restore these files after a device swap or webOS doctor, you will need to follow the directions above on the new device before you run the restore with Save/Restore in order to add that script to the app on the new device.

If you would like to see what files this script backs up (and have some knowledge of how to read save/restore scripts), you can or you can view it on the .

      Hi,
      My TV is driving me nuts!
       
      I keep getting reminders for programs starting for programs I don’t watch or have never watched and 2. The tv even switches on for scheduled programs that I haven’t set.. actually I have only ever set one program reminder and that has now been deleted.
       
      I can’t see any programs in the reminder page or anywhere in the tv programmer?
       
      Short of resetting the tv I don’t know what else to try? And I don’t really want to do that until I know how the tv ended up like this? Plus I don’t want to have to reload and sign in to all my apps 😬

      Anyone have a problem with this app running on LG 4K TV?
      iPlayer app constantly buffers or locks up
      I switch to NOW TV box (not app) & can watch  iPlayer without an issue.
      Also NETFLIX & other catch up apps  work without any buffering or locking.
      Interested to hear your thoughts....

      I have been struggling with the Tidal App on my LG C1. You play music, but it random stops playing. Both on Wired connection and WiFi connect. I basically can't listen to any full song, without the audio randomly stopping.
