We tried extracting and loading the Vu+ file like is done with the Duo2. It will not work for some reason. Still looking for why it does not work like that....
Reload the backup and see if the time date gets restored.
You may save the lamedb file in etc/enigma2 before you reload the backup, then reinstall it after you reload and everything that you have scanned will be there.
You can do the same thing with the settings file in etc/enigma2. The settings file contains all of the receiver settings and the antenna settings.
Use FileZilla to copy and transfer these files. You will need to reboot in order to change the lamedb file, and you will need to hardboot by turning the power off (unplug or use rocker switch on back) after you transfer the settings file.
