If your camera does not detect the firmware upgrade file on its SD card, or if you want to downgrade the firmware version, create an empty text file named force_fw.txt at the root of the SD card, next to the firmware.bin file.

I have followed your setup and tried an updated firmware with the latest firmware available here, and the result is that my cam is not booting anymore. Could you please let me know how to enter in boot/recovery mode, or even a factory flash mode.
And you should take care to the firmware file, may be there are hardware revisions you don't know.
Please help...
