First of all, as I'm new here, let me say that I like your work and I find this forum awesome. And also I'd like to apologize in advance if the answers to my questions seem too obvious for most of you, as I don't have any experience in DVD writing at all (I didn't own a DVD writer until yesterday). That being said, here comes the problem ...
I bought a TEAC-W58G-A, and after I read a lot of posts in here the first step was to change the firmware to LiteOn 812S USOJ. This worked with LtnFW without problems, the drive identified at boot time as SOWH-812S and worked fine. After that I noticed a new firmware revision (USON) on liteonit.com.tw. I downloaded it and executed the file. Surprise: it tells me that there are no applicable drives in the system and it also shows me a list of the drives in the system. It looked something like this:
L is a virtual DVD drive created with daemontools, D is a pioneer DVD-ROM,
E is the W58G-A (now 812S) and F is a Teac W52E CDRW. As you can see the program didn't show any identification string at all next to the drive letter (this also happend with LtnFW)
Ok, so it didn't work like this. I extracted the firmware from the package with XFlash-X and started to update it with LtnFW. It seemed to work for a while (the green LED on the drive was flashing) but after some time it hanged and I had to reset the system. Of course, after this the DVDRW drive was not recognized anymore, so I had to use mtkflash to put it back on line. After flshing the original firmware with mtkflash the drive worked again and I tried to flash USON again, but the result was the same. Anybody has any idea why this happened?
Also, while flashing USOJ from LtnFW in windows I noticed that the drive LED was blinking green until some point, when it blinked red for a fairly short amount of time, returning to green after that. LtnFW reported that everything was fine with the firmware upgrade. Is this a normal behaviour?
Thank you for your help.
Note: I also updated the bootcode.
