sdat2img

Convert sparse Android data image (.dat) into filesystem ext4 image (.img)

This is a C++ equivalent of the original sdat2img tool, which was originally written in Python by xpirt, luxi78, and howellzhu.

Note: newer Google's Brotli format (system.new.dat.br) must be decompressed to a valid sparse data image before using sdat2img binary.

Requirements

This project requires clang to build. Please ensure that clang is installed on your system before attempting to build the project.

• [system_img] = output ext4 raw image file
