Review — "Auto Tool: Unpack/Repack ROM (Android)"

Overview

⚠️ Real Risk: Flashing a repacked image that appears successful but breaks OTA updates or corrupts userdata due to mismapped inodes.

• While it can extract super.img, rebuilding a valid super.img that flashes correctly on VAB (Virtual A/B) devices often fails.
• The tool sometimes doesn’t set proper group and extent metadata, causing “Invalid sparse file” in fastbootd.

Cleaning Tools: Built-in "debloat" scripts to remove system apps.

Once unpacked, the ROM is "open." This is where the user performs: Debloating: Removing pre-installed system apps.

• Odin flashable (Samsung)
• Fastboot flashable
• TWRP flashable ZIP

Sparse Conversion: To save space and ensure compatibility with flashing tools, the raw image is converted back into a "sparse" image.
