451s firmware GSB5?

I bought Liteon 451s last week. It came with firmware version GSB5. Anyone know anything about this version? I haven’t seen it anywhere else…

Might be bad because it isn’t listed in Liteon pages. I have done some testing with cd-rw disks and results are very poor with Nero and Recordnow(large damaged areas and some unreadable parts)

What is the simpliest way/program to backup the original firmware before upgrading?

this should help

Yeah, use LtnFW.

Send me your backup if you don’t mind.
