LTR-16102B IBM OEM firmware

Hi, I need a little help with identifying my firmware.
I know that I have a Lite-On drive “LTR-16102B” it was purchase as IBM OEM “IBM P/N 24P3630”, my firmware is “OUS3”, as you can see it is not according to usual Lite-On numbering system as “OS0J” or “OS0K”,
First off all does anybody knows which Lite-On firmware is equivalent to mine. Can I use the usual updates to update my firmware, and how can I do this, because the install program don’t “like” my firmware and refuses to install. (Should I do this in DOS)

you can make it with MTKFLASH to the original liteon :smiley:
