I'm having issues when trying to upgrade firmware of my DNR-322L ver A2
Currently I was able to upgrade from 1.2 to 1.4b01 and then to 1.50b03
After that, no other firmware allows the device to be upgraded.
i've tried already these ones with no success and I get the same message all the times: FIRMWARE UPLOAD FAIL, TRY AGAIN
