ADB Download All Files - A dirty shell script to adb pull all readable files using adb pull & base64

If you are reverse engineering a hardware Android device, and was to see what interesting files you have read or executable permissions over, then this will mirror all touchable files.

adbfs-rootless is great, except it shows unreadable files by the adb user.

Script

This script is the also found in ./adb-haul.sh
