LG L90 does not find backup on the phone
So I made a backup and putted it on my micro sd, and then from the sd to my computer where there is now a 2,5 GB file called (.lbf), thats the backup.
I then putted the backup back on my internal memory on the phone. When i open the recovery option in LG Backup app, the file is nowhere to be found. When i make a new backup on the phone (just a test backup from 2 MB), that one does appear in the recovery option. So how do i make the other one appear, is it broken? I have made 3 backups on the sd and all of them don't work when i put them back on internal memory.
