🎯 Quick Start

# Extract firmware
samfwtool extract firmware.tar.md5 -o output/

# Analyze firmware
samfwtool analyze firmware.tar.md5 --security --deep

# Modify boot image
samfwtool modify boot.img --extract-kernel --extract-ramdisk

# Repack firmware
samfwtool pack output/ -o custom_firmware.tar.md5

# Compare firmware versions
samfwtool diff firmware_v1.tar.md5 firmware_v2.tar.md5

# Generate OTA package
samfwtool ota --base firmware_v1.tar.md5 --target firmware_v2.tar.md5
