Auto Tool: Unpack Repack Rom Android

With Android 15 (Vanilla Ice Cream), Google is introducing and mandatory VABC (Virtual A/B Compression) . This means ROMs will become even more fragmented:

Tool-Tree supports both root and non-root devices for ARM64 architectures. It places ROM files in /sdcard/TREE and APK files in /sdcard/TREE/APK , with root paths at /data/local/TOOL for APKs and /data/local/TREE for ROMs when rooted. It includes add-ons for ROM and APK editing.

For users who prefer command-line tools, Magisk's magiskboot binary offers precise control. The unpack command ( magiskboot unpack boot.img ) extracts the kernel, ramdisk, DTB, and other components. After modifications (e.g., replacing the kernel or editing the ramdisk), run magiskboot repack boot.img to reconstruct the image. The tool automatically detects compression formats and preserves special headers like those used by MediaTek devices.

Repacking is the most critical stage. It requires precision; one wrong byte in the metadata can result in a "bootloop." auto tool unpack repack rom android

If dealing with dynamic partitions, the tool will rebuild the super.img file ensuring the combined size does not exceed the physical partition limits of the target device.
