+# 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
