  • Industrial embedded devices – Legacy medical displays and automotive infotainment systems rely on USBUtil recovery.
  • Educational purposes – Teaches low-level NAND flashing without JTAG or expensive programmers.

Newer tools like stm32flash (open-source) and dfu-util offer similar functionality, but they lack the graphical simplicity and bad-block management of USBUtil v2.2 rev1.0 EN. For many technicians, it remains the go-to first aid kit for bricked STi devices.
