Hi. My LG BP50NB40 has just arrived, and it's reading a red cross next to "MT1959 Platform:" in SDFtool
Obviously, can't read or write firmware this way. Fix?

If its an 1.00 revision then its is mt1939 and a bu20n internally and unable to flash. Don't try flashing it with the other flashers as it will just brick.
