# Pull prop settings from image files using AIK
# ipdev @ xda-developers

# Originally (and still) written to grab needed/useful props for use with MagiskHide Props Config module
# by Didgeridoohan @ xda-developers
# https://forum.xda-developers.com/apps/magisk/module-magiskhide-props-config-t3789228

# To pull props from a boot or recovery image file requires unpacking the image.
# This script relies on Android Image Kitchen (AIK)
# by osm0sis @ xda-developers
# https://forum.xda-developers.com/showthread.php?t=2073775

# To use.
# Install AIK
# Copy the boot and/or recovery image file(s) into the AIK directory
# Copy aik_mHideGP.sh and mHideGP.sh into the AIK directory
# Copy extra prop files into the AIK directory (optional) (See Update Note below.)
# Run aik_mHideGP.sh
#
# This will run the unpack and mHideGP scripts on all image files in the directory.
# Merge the generated mhp files into mHide-printslist-DATE.sh.
# Remove all the generated mph files.

# If used with another method, make sure to make changes in the script(s) accordingly.

# Update Note.
# This script now supports additional prop files.
# It will also look for files ending in: build.prop default.prop prop.default or getprop.props
# in the same (AIK) directory.
#
