I have several Boron devices that returned after being deployed in the field for a few months, but they are now showing 10 red blinks, indicating an assertion failure. I attempted to restore them using the JTAG, but unfortunately, I have had no success. The failure consistently occurs when loading the bootloader file. Is there anyway to bring them back to life even if I need to buy a better JTAG. It appears the internal MCU flash is corrupted.
