Fairphone updater app doesn't stop crashing. Unable to open it and to update

@Es_Ter You might have to install Fairphone OS 1.8.7 again. By doing so, also Backup & Restore would be installed again and, hopefully, work afterwards.

@toganeger Titanium Backup is there to backup apps, not to delete them! :wink: On a serious note: Titanium Backup should not delete anything on your phone.
