📱 Extracting Files from an Old Android Phone to macOS using ADB

Connecting an approximately 10-year-old Android phone (likely Android 4–6) to a MacBook is tricky, because Google has barely maintained the official Android File Transfer (AFT) app for years and older devices often only support MTP (Media Transfer Protocol).

This guide explains how to copy all accessible files from an older Android device to a Mac using ADB (Android Debug Bridge).
It works even if your device is 10+ years old, as long as you can enable USB debugging.

1. Prepare the Android Device

thomashartm

#!/bin/bash

# Check if the correct number of arguments is provided
if [ "$#" -ne 2 ]; then
  echo "Usage: $0 <source_directory> <target_directory>"
  exit 1
fi

SOURCE_DIR=$1
TARGET_DIR=$2

thomashartm

#!/bin/bash

set -e
# Enable -x only for debug purposes
#set -x

# Retrieves a JSON parameter from SSM and output them as key/values
# ./create-env.sh -p <system manager param name>
# Write the output to .env.local
# ./create-env.sh -p <system manager param name> > .env.local

thomashartm

 #!/bin/bash
 
 # usage:
 # ./remove-terragrunt-state module.s3_bucket ../../../
 
 TOKEN=$1
 SOURCE=$2
 
 terragrunt state rm $(terragrunt state list  --terragrunt-source ../../../ | grep $TOKEN) --terragrunt-source $SOURCE
