A corrupted flash can leave the Chromebook entirely unresponsive (no power, no display).
Firmware is not one-size-fits-all. Using a ROM meant for a Bay Trail or Braswell Chromebook on an Intel or ARM-based device will cause a hard brick. Always cross-reference your exact Chromebook board name and processor generation with the supported hardware lists provided by firmware developers.

Security experts note that .bin files are not inherently executable on Windows, but once you run an included .exe file, you could be infected.
It is not a mainstream consumer app, but rather a specialized tool for users who have converted their Chromebooks into Windows or Linux machines. Key Features Firmware Management
While tools like CBWinFlash offered significant utility in the past for Windows-on-Chromebook projects, the community has largely shifted toward modern Linux-based live USB environments. These live environments handle firmware modifications with significantly higher stability and fewer multitasking-related OS interruptions than executing commands inside an active Windows operating system.
