I just downloaded new bootloader Firmware to my FRDM-KW40Z board and the board now appears dead, it did flash LEDs before I copied the new firmware.

The Firmware I donloaded was k20dx128_frdm_kw40z_cmsis-dap.bin from http://cache.nxp.com/files/32bit/software/k20dx128_frdm_kw40z_cmsis-dap.bin 

How can I recover my board?

Kindest Regards,

Carlos
