(Chromebook Windows Flash Utility) is a specialized open-source software tool designed to update, back up, and flash custom Coreboot BIOS/UEFI firmware directly from within a Windows environment on supported Chromebook hardware . Originally developed by the prominent independent developer CoolStar , this utility acts as a specialized graphical user interface (GUI) wrapper around low-level hardware flashing mechanisms—such as the Intel Flash Programming Tool (FPT)—eliminating the need to boot into a temporary Linux environment just to manage or update full ROM firmware on cross-platform "Chrultrabook" modifications. If the process is interrupted, your computer could
