Since various applications use BIN files for multiple purposes, you may be able to open some BIN files but not others. For example, some apps allow you to save and load BIN files, while others reference them when the app is running. I don’t want to compile the file or make it actually run, just want the bin file out of it. Thanks popey for explaining why just copying the .bin file didn’t work.

The -5 flag makes strings search for 5 or more printable characters in a row. We use |head at the end to limit the output of the command to first 10 lines found.

  • It’s always a good idea to only download .bin files from trusted sources and to use caution when stock ROMs opening them, as they may contain potentially harmful code.
  • Similarly, if the .bin file is a disk image, you may be able to open it using a virtual drive app.

  • RepRap, Marlin, and Klipper are all very popular choices when it comes to choosing a firmware for your 3D printer.

Any TRX style firmware image format should that uses squashfs-lzma as a root
file system work fine. Firmwares that use regular zlib squashfs or unsupported
file systems will work if the steps that extract the file system and rebuild the
file system are tweaked.
