How to restore backuped Themes (.bak file)?

[Neria]

Hello,
Before reinstall my phone I made local backup (settings, messages, contacts and themes). After new ROM instalation I put my backup file into "Allbackups" folder and then I loaded it directly by my phone. Everything was imported correctly, but for some reason my phone didn't restore any theme. In my backup folder there is a file named Motywy(com.android.thememanager).bak, so it is here. How can I restore it from .bak file?

If this method does not work, you can change to another method. Transfer the local backp files to the computer first, and then import it from the computer to your phone.In this way you can restore the backup easily.As for transferring files from the computer to the phone, you can try the MobiKin Assistant for Android, which can connect the phone to the computer and allow you to transfer files from computer to device.
