My LDW-851S crapped out recently, and had the GS0P firmware on there. It basically can detect the drive and even read the disc label, but cannot read any of the data on the disc. I'd like to try to downgrade my firmware to GS0K or any previous one to see if it will fix my problems. RPC1 seems to be down, and the mirror does not list any firmware for this drive except the latest one. I've already tried reflashing with the stock firmware of the latest one and no go. Please help if you can provide the older firmware for this drive. Thanks.
