TinyCLR Config v2.3.0.1000 crashes when connecting to FEZ Flea

When trying to update a FEZ Flea with TinyClr Config to update the firmware to “SITCore-SC13-Firmware-v2.3.0.2000”, I got an error message that the firmware could not be loaded and now TinyClr crashes when trying to connect to this FEZ Flea. Trying to connect in loader mode will also produce the same result.

How can I solve this problem?

With other FEZ Flea the firmware update works

Put the board on loader mode using ldr pin. Erase all then update the firmware
