Extracting system.new.dat.br

Requirements:

• system.new.dat.br
• system.transfer.list
• sdat2img.py

The first layer is composed of Brotli compression:

$ brotli -d system.new.dat.br

You should now have a system.new.dat file, up next: converting to an img with sdat2img:

$ sdat2img.py system.transfer.list system.new.dat

You should now have a system.img file that you can mount:

$ sudo mount -t ext4 -o loop system.img /mnt/tmp
