Optiarc BD -5840H 1.M5


I have a BD-5840H, it can read CD with DVD, in addition to BD, I confirm that the firmware problem. But I can not use BINFLASH for processing. OPG is mc-10182. I hope for help, because it was my job, andSony Optiarc to cease operations, so I was willing to pay for it.
I know that this is a place of interest, I do not know how to do it. Please forgive me
