What's new
Starting from Liteon firmware version 83850 V2, there has no easy to extract the key. Thanks to MRA at XBH, he figured out a way to extract the key with lifting the legs of the chip. However, it still requires soldering wires on the PCB.
In this tutorial, we are going to show you how to extract the key from a 83850 V2 or 93450 without soldering anything on the PCB.
Tools required
You will need access to 3.3V and GND, thus you need our own brand of DVD power adapter, which has easy access to 3.3V and GND.
- XBOX 360 case opening tool with TORX bit. Buy from [here] or [here]
- Access to your PC's native SATA port, or a PCI to SATA card. A VT6421A powered PCI to SATA card works best. USB to SATA convert does NOT work. Buy VT6421A PCI to SATA controller card from [here] or [here]
- A XBOX DVD power adapter. Buy from [here], [here], [here], [here]
- TIAO's 83850V2 and 93450 Solderless Key Extractor. Buy from [here] or [here]
- Dosflash 1.8+ [download] and Jungleflasher 1.67b+ [download]
- ixtreme 1.6 Liteon templates, check xbins.org
To make your life easier, we have created a package, contains the XBOX 360 Connectivity Kit V3 and 83850 V2 and 93450 lite-on DVD drive key extractor.
OK. Let's get started!
Remove the Liteon DVD PCB
The first step is to remove the Liteon DVD drive from your xbox 360, if you don't know how to do that, you can google it.
Once you have the DVD drive removed from your XBOX 360, remove the cover and then locate the two screws and remove them:
Then unlatch the three flat cables as shown in the pic:
Now you have the cables removed:
Carefully remove the PCB from the DVD drive housing:
Make two cuts on the PCB
Close up of the PCB:
We will be working on the circled area in the above picture. Here is a close up of the AOI.
As you can see from the above picture, we need to make two cuts (A and B).
First, use a utility knife, carefully remove the paint above the PCB trace at A and B:
Then, use a sharp utility to make a V cut at point A and straight cut at point B, do NOT cut too deep, and be gentle. You may want to practice before you make the real cut. For point A, it is recommended to make the cut as shown in the pic, in the middle of the trace. The purpose of this cut is to isolate the pad from the 3.3V line and also keep the 3.3V line connected. For point B, just make a straight cut as show in the pic below. Again, be gentle and practice many many times before work on the PCB!!!
OK, the result:
If you have a multimeter, it is recommended to check you have isolated the pad from the 3.3v line and you have broken the trace at point B. If you don't have multimeter, then it is still ok, but you will have to make sure it is done correctly.
