# Magisk Uninstaller

# by topjohnwu

# This script can be placed in /cache/magisk_uninstaller.sh
|
||||
# The Magisk main binary will pick up the script, and uninstall itself, following a reboot
|
||||
# This script can also be used in flashable zip with the uninstaller_loader.sh
|
||||
#
|
||||
# This script will try to do restoration in the following order:
|
||||
# 1. Find and restore the original stock boot image dump (OTA proof)
|
||||
# 2. Restore ramdisk from the internal backup (ramdisk fully restored, not OTA friendly)
|
||||
# 3. Remove added files in ramdisk, modified files are remained intact. By doing so, Magisk
|
||||
# will not be started at boot, but not removed clean enough
|
||||
#
|
||||
# Finally, this uninstaller will remove all Magisk related files
|
||||
# (The list is LARGE, most likely due to bad decision in early versions
|
||||
# the latest versions has much less bloat to cleanup)
