WARNING: This will void your warranty. Do so at your own risk. If done properly the risk is almost zero. Owners of the Liteon SOHW-812S can upgrade their single layer burner to a SOHW-832S burner with a firmware upgrade. Only downside is that you will then need Nero 6 to burn dual layer disks. Saw this on a video but since it was made (a couple of weeks ago) there has already been another firmware upgrade. 1/ Grab OmniPatcher for LiteOn DVD-Writers . As the firmware has already been updated I'm not sure if you will need the new tweak file found at the same page. Won't hurt grabbing that as well. Not sure where it fits in though. It simply goes into the omnipatcher folder replacing the one that is already there. (It contains a readme file)[/edit] 2/ Grab theDR8VS0A.zip. 3/ Also get dvd info pro if you want to compare the before & after results. 4/ Install dvd info pro now to see the 'before'. a/ Install & open OmniPatcher. Put the latest tweaks in the omnipatcher folder[/edit] Load the firmware using the 'Load' button. b/ Click 'Apply recommended dvd media tweaks'. c/ Tick 'Fix the "Dead Drive' blink / Enable cross flashing. d/ Click 'Save As' then name you new firmware update file. e/ Open the new firmware file, READ the warning. f/ The target drive is your 812S. Click 'Update' & wait for it to finish. g/ OK. Now it is time to reboot. f/ Open dvd info pro & see the 'after' result. You now have a SOHW-832S dual layer burner. Happy burning.
