Hi, I’ve been following alot of the messages on various firmwares, and “upgrading” your older Lite-on to 48x writer via Mtkflash, and the appropriate firmwares, the plus and minuses, that sort of thing.
Quick story, I have a Lite-on LTR-40125S, for a number of months now. The last time I had upgraded the firmware was to ZS0A. Didn’t think much of it, after all, newer firmware, better performance, right? With ZS0A, that is true, I haven’t had a single problem with it.
So, I get looking, and find hey, there is ZS0J available! Great, I say, and oh look, is says it is compatible with more media. Sure why not, flash that sucker. Well, big mistake, I got about 6 coasters from it, all from using Sony CD-R’s, rated 32x, and I had burned them as slow as 24x just to be sure. Some were more or less readable, actually they all “worked”, as in came up with the install menus, but checking them with Nero, they had several errors, and a couple failed, and wouldn’t read further. So I try with Maxell, and Memorex…they both did ok, so I’m thinking my Sony CD’s are to blame. Well, back when I was using ZS0A, I had burned a few of the Sony’s, (same type), and so I dug the discs up and tested them with Nero again. No errors! Well…couldn’t have been the Sony’s, maybe it was the ZS0J flash that was to blame?
Finally, I decide I’m going to go back to ZS0A, and with the help of Mtkflash (great program BTW), and after I had converted the .exe file to .bin, and did the whole process again, thanks to OC-Freak for his little collection of older roms, and thank God, because Lite-on had taken down the link to ZS0A, I reflashed my drive, burned some Sony’s at top speed, 32x rated like before, checked for errors in Nero, and viola, NO ERRORS this time.
I’d have to conclude, ZS0A is probably the most compatible flash, I have used several types of media in it no problem, and zero errors too. If your getting errors, no harm in going back, you can do whatever you want with Mtkflash.
