# 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 with the following:
|
|
# 1-1. Find and restore the original stock boot image dump (OTA proof)
|
|
# 1-2. If 1-1 fails, restore ramdisk from the internal backup
|
|
# (ramdisk fully restored, not OTA friendly)
|
|
# 1-3. If 1-2 fails, it will remove added files in ramdisk, however modified files
|
|
# are remained modified, because we have no backups. By doing so, Magisk will
|
|
# not be started at boot, but this isn't actually 100% cleaned up
|
|
# 2. 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)
|
|
