sdat2img

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

Requirements

This binary requires Python 2.7 or newer installed on your system. It currently supports Windows, Linux, MacOS & ARM architectures.

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

Usage

sdat2img.py <transfer_list> <system_new_file> [system_img]
  • <transfer_list> = input, system.transfer.list from rom zip
  • <system_new_file> = input, system.new.dat from rom zip
  • [system_img] = output ext4 raw image file (optional)

Example

This is a simple example on a Linux system to Extract system.new.dat

~$ ./sdat2img.py system.transfer.list system.new.dat system.img

This is a simple example on a Linux system to Extract vendor.new.dat

~$ ./sdat2img.py vendor.transfer.list vendor.new.dat vendor.img

OTAs

If you are looking on decompressing system.patch.dat file or .p files, therefore reproduce the patching system on your PC, check imgpatchtools out by @erfanoabdi.
