Restore SeedVault Backup This guide assumes you have been backing up your GrapheneOS using SeedVault in a WebDAV mount that you mounted using DavX5. After initial setup, install DavX5 and re-mount the original WebDav share you previously used to perform the backups. In your phone dial pad, dial *#*#7378673#*#*   in order to bring up the SeedVault restore screen. Enter your SeedVault Recovery Seed words and pick the backup you wish to restore.
