Thanks to MRA at XBH, based on his great idea, we have developed a kit allow you to extract the key from 83850 V2 and 93450 without soldering.
This is the picture of the kit:
Overall diagram:
The advantage of this method is, you only need to rejoin 2 points on the PCB. Other methods involves at least 6 points, I mean you need to remove paints on at least 6 points, and you need to solder on at least 6 points on your Liteon DVD PCB. Our method only involves 2 points. The advantage is very clear. Even if you want to solder, our method is better for sure.
This is the steps to extract the key without soldering:
(You need DOSFLASH 1.8 or higher, Jungleflasher 1.67 or higher and ixtreme 1,6 firmware template for your version of DVD drive)
Step 1:
Remove the DVD PCB from your DVD drive, locate the Area of Interest:
Step 2:
Make a V shape cut at the R101 trace and cut the trace at location B, use a multimeter to make sure the cuts are good:
Step 3:
Prepare the key extractor kit, insert the 22 Ohm resistor to the female headers and pogo pins to the headers:
Attach the alligator clip to DIYGADGET's DVD power adapter:
Step 4:
Hold the 3.3v pogo pin to the point B, hold the resistor pogo pin (connected to GND via a 22 ohm resistor), then turn on the DVD adapter and launch DOSFLASH:
DOSFLASH will show status 0x72:
Step 5:
Then while keep the pogo pin on point B, but carefully lift the pogo pin from point A to disconnect it:
Then click 'Read Firmware' on DOSFLASH, then you will have your firmware:
Do it multiple times to make sure everything is right. You may want to do a binary comparison between each dumps.
Step 6:
Now we need to rejoin the cut trace.
Use Silver Conductive Wire Glue, do NOT use carbon based wire glue, they are not thick enough may mess you your pcb:
Put tiny amount of the silver conductive glue on the broken trace, remember tiny amount, you can add more if needed:
Let it dry for a few hours, use a multimeter to make sure the traces are back to original status, this is very important.
Then put the PCB back to the DVD housing.
Step 7:
We need manually spoof the firmware, you need jungleflasher 1.67 or higher, you need the ixtreme 1.6 template, google it.
Launch Jungleflasher, click open target firmware, select the firmware you just dumped from your liteon:
Then copy the key to your clipboard:
Then click 'open target firmware' button again to load the ixtreme firmware template for your version of liteon:
Then click manual spoofing:
In the dialog box, delete the default key and paste it with your own key copied from the previous step, then click ok:
The click 'Save to file' to save the spoofed firmware:
Once you have done that, you can follow the following tutorials to flash the spoofed firmware to your liteon:

Troubleshooting:
If you got status 0x80, 0x52 or 0x51, turn off your dvd power adapter for 5 seconds and turn on again, it may change to 0x72.
If the above does not work, try to replace the resistor to a lower value, e.g from 22to 20, or from 20 to 18, from 18 to 16 and try again. Do not go below 16.
If your PC freezes when you turn on your DVD power adapter, you can do it in DOS (use DOSFLASH 16bit version in DOS), or change your SATA driver to UNIATA driver as mentioned in the following tutorial and the do it again:
