Crossflash my SONY DVD RW DW-23A to LiteOn SOHW-1653S



Dear All

Freash newbee here so a big hello to everybody.

I have a Sony DW-23A version CYS1 Firmware. that I need to cross flash To obtain more current up to date Firmware Sony DW-23A has no other updates available.

I need to make it think it is a LiteOn SOHW-1653S
The CodeGuys Web Site ( has detailed information on crossflashing Sony DW-23A to LiteOn SOHW-1653S.

but I keep coming up with 7 downloadable firmware files, of which I have identified 3 … but I have no idea which one of these files I should use to crossflash my drive.

Here are the 3 choices … but I am unsure as to which version of Firmware I need

Download 1653S CS0T FB:
Download 1653S CS0T FBD:
Download 1653S CS0T FBDX:

Hopefully I can get some help from an experienced hand on this site

Kind Regards



@ corrie9090,

Welcome to the CD Freaks Forum.

I believe Forum Member Sony0 over at The Firmware Page Forum ( explained what the three LiteOn SOHW-1653S version CSOT Firmwares provide. Also Forum Member Sony0 provided a CD Freaks Forum posting Web Link concerning the LiteOn SOHW-1653S version CSOT Firmwares. It appears from your above posting that you have not reviewed the below referenced Forum posting that Forum Member Sony0 provided for you.



Yes you are correct on that score … but clearly I am not understanding this
when ever I burn DVD’s I just use nero and everything just happens … burn speeds etc just never entered my mind

Now I am faced with a choice that I do not really understand … that is why I am here since this is the site that contains the firmware

I expect that otheres viewing this post would find the answers very obvious … but I am afraind I am not in that catagory


Ahh … just seen his “personal choice” reply i.e sony0


I agree with the poster that has directed you to the right place and the right person for your questions.


I All

My crossflash was a success and apologies for my post in this codeguys forum … I had to be as sure as I could be since this crossflashing can be a can of worms

my Sony DW-23A now says it is a LiteOn SOHW-1653S which I think must be a + result … now all I have to do is understand imgburn ( I will never ever attempt to drag & drop ) … and my drive use should improve from here on in




No need to apologise, it’s always better to ask and do it right than to do something wrong because you didn’t ask. :wink:
