Ok I spent all night looking for LDW-811S firmwares and I finally found them all.
out of these I was able to patch the updater to downgrade from a newer version..
This one has encrypted string section will need to decrypt it or find the proper code segment..
these two i need to trace some more to get them working
the place you can download the frimwares is
Reason I went through all this trouble is because i noticed that the HSOR has problem reading dvd's even ones i have burnt in the past with the same drive..
its a weird type of error even.. some of the cd can be read like text files or a section of the cd like maybe one cd image but not the whole thing makes it feel like part of the disc is corrupted but its not my other drive can read it fine..
I went from HS0R to HS0K and was able to read dvds correctly again..
hope this helps a few people..
