I just got an OEM 811. The current firmware is HSG1 dated 2003-11-05.
First off I don’t know if this is the latest available but anyway I tried running the HS0E updater but it says I don’t have an LDS-811S. It says I have a DRW-1S81.
I also tried the HSTQ firmware and I get the same error as above.
Is there a way to flash mine with the retail firmware?
