The Hardware Tool Emergency Boot Firmware Recovery Utility
Only use this utility to restore hardware tool boot firmware to its factory state.
Use only if your hardware tool no longer functions on any machine.
The debugger may need to be forced into recovery boot mode (reprogrammed) in rare
situations. For example, if none of the LEDs are lit when the debugger is connected to
the computer.
YOU MUST USE MPLAB X IDE V5.05 OR GREATER TO USE THE EMERGENCY
RECOVERY UTILITY FOR THE MPLAB SNAP.
Carefully follow the instructions found in MPLAB X IDE under the main menu
option Debug>Hardware Tool Emergency Boot Firmware Recovery. After the Warning
screen, select MPLAB Snap.

If the procedure fails, try it again. If it fails a second time, contact Microchip Support at
