Is it possible to unpack this firmware for ZXIC chipset device?

I tried to unpack it with binwalk but wasn't successful and I saw this information:

  • Are you using the -e flag?

  • ok, thanks for your answer, must i need to use Linux to do it, because jefferson can't install on Windows with python. And when i use binwalk -e it shows this image, but we can't find uboot.bin, z-loader and others files. ![binwalk output](i.stack.imgur.com/dKBjl.png)

Install jefferson, which is unpacker for jffs2 file system used in your image, if it is not installed yet, and run binwalk -e -M firmware.bin -C [result folder]

I checked this with your firmware, works fine. If you have problems with your run try to update your binwalk and other utilities it uses.

  • -M flag is for "matroshka" mode, it will unpack everything potentially unpackable inside the already unpacked images.
  • -e is for extraction
