I’m about to switch my outdated Samsung tablet and smartphones to LineageOS. But I want to make a backup of my device, including the OS and everything, in case something goes wrong and I need to flash the original OS back into the device.
How do I proceed? I think I need to do a Nandroid backup or something? Is that correct?
i’ve heard good stuff about Swift Backup and Neo Backup. but personally i’m on android 8 and 11, still using titanium backup since it works well enough.
Thanks, I’ll take a look.
If you ever want to restore on a newer Android (at least I needed this on lineageos with android 15 or 16), you need to fix SELinux permissions on the data files. This is the script I use after restoring, but before starting the app. Maybe it helps.
#!/bin/bash # Fix restored file permissions by copying permissions from parent directory set -euo pipefail if [ "$#" -ne 1 ]; then echo "Usage: $0 /data/user/0/<appname>" exit 1 fi APP_DIR=$1 SEL_CONFIG=$(getfattr -d -n 'security.selinux' $APP_DIR | grep security.selinux | cut -d'=' -f2- | tr -d '"') find $APP_DIR -exec setfattr -n security.selinux -v "$SEL_CONFIG" {} \;
