problem flashing liteon aoa1 74850c drive

[adamdl81]

Ok first off here is what I am using.
ck3 lite
probe v1 and 2
gigaware usb to serial adapter
liteon aoa1 74850c
via 6421 with viaraid renamed in sys32


So my problem is this. I have successfully flashed several liteon drives to this point. My buddy gave me his box to flash and I said no problem. Plugged everything in opened JF drive showed up. comport showed up. clicked get key and got bad serial data msg. Went to ck3 tool got invalid key when using probe. tried the old faithful r707 bridge with screwdriver and got a key. however apon multiple dumps the keys didn't match it was different everytime. I went back to JF and tried the bridge and got bad serial data. Does anyone have a idea as to what it may be? I have replaced my ck3 lite and probe still having the same issue. Since I am using the lite i only have the serial cable option. My XPS doesn't have a serial port so I am using a gigaware usb serial adapter. This has worked on previous flashings and I have since replaced this as well. I'm starting to lose hair and sleep over this drive. Been through 100's of posts and tried just about everything. Including probing the r52 hole next step is to try to get the key from motherboard. I would prefer not to have to go that route though.

Use a spare drive, and flash one of the key's into it, if it doesnt work, try the other.

If one of them work's, then use that key and build a CFW for the drive, and flash.

Thanks for the help. I have tried that a couple times with no luck. Everytime i dump for the key in ck3 tool it's different. I have about 50 different key so far. tried flashing 10 to a backup liteon. which I was able to extract the key from with no issues. none have been the right one so far. Drive still plays originals when hooked up. but with all the different keys im getting. im starting to wonder if something is corrupt as jungle flasher says bad serial data everytime and no 2 keys being the same in ck3 tool.

im not understanding this

dump for the key in ck3 tool

no 2 keys being the same in ck3 tool.

just use jungle flasher and
see what jungle flasher tells you about the keys

i may not be understanding what you are doing

i think i also read that there was some of the very last 74oo dvd drive that in fact had the 8300 firmware
im not 100% on that
i cant find what i read about that know.
