Warning to all Lite-On burner owners… DO NOT UPGRADE YOUR FIRMWARE! I own a LTR 32123S (32 Speed) burner and last night I downloaded the latest firmware from Lite-on and immediately installed it Guess what it did? I can no longer backup SafeDisk V2 CD’s. I tried to do it on numerous occasions using different games without success. Even the games I have so successfully backed up before, now refuse to copy correctly or as before.

Yep!! I fell into that trap also.

The good news is that it is possible to revert back to your original Firmware.

When I have the new hacked Firmware to revert I'll post again and email it if anyone needs it.

From what I gather, all you have to do is use a hex editor on the firmware and change the first value to that of a newer version, then you can update to an older firmware version...

However some people are reporting that they can still do SD2 just fine with the latest firmware.

And how would you do that if you're not proficient in hex, hmm?

I've checked both the EXE and the BIN files and cannot see a date code anywhare obvious.

Using [b][url=********wald.heim.at/sherwood/530742/dvd/mt/mktflash_138.zip]MTKFLASH.EXE[/b] on drives using the MediaTeK chipset one can extract the BIN file from the drive and reflash another one (as long as it's the same model number). It's been done before, check at the bottom and the next page of [b][url=***********.cdrinfo.com/forum/topic.asp?TOPIC_ID=4579]this post[/b]

All you need now is someone with the same drive as yours (soory I don't), unflashed, the MTKFLASH.EXE utility to read the Flash Rom and have it sent to you

. You'll need MTKFLASH.EXE as well with a bootable diskette to flash the drive in pure DOS. I'd say it's easier than attempting to modify the firmware file in HEX...

Celtics right about the procedure.

The Flash will fail if you try to flash with an earlier version.

Ultra Edit 32 has been used to modify the first entry of the Firmware.

Once you have the original 32123S Firmware then this original Firmware is edited. The first entry of the Firmware is modified to indicate its an updated Firmware.

The drive is then Flashed with the Hacked version to fool the drive into reverting back to the original Firmware.

I know what I mean anyway
