CONFIRMED! Here's the way I did it. I downloaded just as tydas described above. Created a startupdisk in Windows XP. (Right clicked on floppy in My Computer and Format - then clicked on MS DOS startup disk and formatted). I then had to delete the Keybrd2.XXX, Keybrd3.XXX, EBD2.XXX, EBD3.XXX (where XXX is the extension I don't remember) files to make room for a backup .bin file. After creating the disk, I copied mtkflash.exe and Xs0U.bin to the floppy.
1. I rebooted by floppy.
2. Made a backup of the bin file by typing (MTKFLASH_"1"_R_/B_/M_backup.bin) "_" are spaces.
********** The number "1" is for the drive being on the Primary Master IDE Channel***********
(I suggest you read the details for another type of drive on the CDFreaks site).
3. Rebooted as told.
4. Wrote the new bin by typing (MTKFLASH "1" W /B XS0U.bin)
5. Rebooted as told.
Step 2, making a backup, took a while, around 3 min, and writing, step 4, took a minute or so. That's it! Now I have an LTR-32123S.
Edit: A couple things CDFreaks said:
1. Not to boot up any CDROM drivers. Delete them off floppy if you formatted some other way than I have.
2. Put the drive to Primary Master.
3. Don't forget to do step 2 and backup.
4. Be careful! I have a Verbatim 321240AL X8S2(at startup). It was flash type: SST(SST39VF040) when I backed it up.
