This is really "confusing"...
1st let me quote from Svenson in thread (3rd page) http://forum.cdfreaks.com/showthread.php?s=&threadid=91091&highlight=eeprom
"*) The Ldw851fp program will modify a LiteOn provided firmware update program to allow it to load the 851 firmware into the 451 properly. You?ll have to look around for this program, but it?s easily found.
*) Every time you want to upgrade the firmware of the drive with the newest 851 firmware from LiteOn you will need to run the patch program as the EEPROM is not changed and the upgrade programs will recognize it's not an 851 drive no matter what firmware is currently in it. "
As far as i've known and found out, Ldw851fp removed the checking of official win-update.exe. It also adds 8x burning for some medias. But no matter what, the hacked update.exe will do nothing on the eeprom!! Am i right??
My friend just bought a new 451s(GSB6) with no update/upgrade, all original. And he bought this crappy media AN31 that i wouldn't even touch!! However, he said the burn is perfecly fine at 4x and it plays very smooth in his ps2. So, i was thinking what the heck is wrong with mine!! Even though i've read hundreds of threads on no-good burns on crappy medias, but i've also heard many sucessful cases!!
So i changed back from 851@GS0A to 451@GSB6. Then I used ltnflash124.exe to compare the firmware bin with my original GSB6 backup with the fc command, differences showed up, then i used my original GSB6 with ltnflash124.exe and then back it up and compare thme again. Still, SAME differences showed up. Anyway, I've read something like this somewhere, and it's pretty normal!!??
Which surprised me was when i compared the eeprom with my original, differences showed up!! WHAT?? How could this happen?? What have i done wrong?? What changed my eeprom?? Please help...
So, i flashed the eeprom with original and burned a data dvd with the cheapy media DVSN at 4x. And the dark circle is gone and the disc reads fine!!
SO, WHAT changed my eeprom, Ldw851fp??
