Help please for firmware update 1-0-1-0 G:LITE-ON DVDRW SOHW-1633S BPSA

Hello, can you help me please,
when i execute the official Window flasher firmware BS0Y.EXE for LITE-ON SOHW-1633S download from
there is the message :

No matched drive detected !
This utility is only for LITE-ON DVDRW SOHW-1633S drive.
Detected drives :

(when i burn a dvd-r with this drive , NeroCD-DVDSpeed show me :
“recorded with SONY DW-D22A BPSA” )

Can i flash the file BS0Y.EXE with flashfix.exe and run it ?
Will it update my drive with out any problemes ?
I’m a little bit scared :confused:, can someone tell me with surety that it will work with no probleme ?
Or should i make a crossflashing ?

Thank you.

The firmware in your drive is an OEM version, that’s why the official LiteOn flasher don’t work.
You can use the unscrambled BS0Y firmware from the CodeGuys,

or, even better, upgrade (crossflash) your drive to a 1653 by using this firmware

I was a happy user of CS0T in my 1633 from the moment it was available until the drive died a few months ago.

Tip: Backup your firmware using the Flash Utility provided on the forum. And if you decide to go to a SOHW-1653S, also be sure to back up your EEPROM. :flower:
