With X360USB PRO you don't need CK3 Pro drivers, you don't have to use any COM ports (if you don't want the "no Com Ports" message showing up when you boot Jungle Flasher then simply save and run this reg file) and you don't have to have any PortIO stuff installed so no F8 or Driver signing disabled or any of that crap any more (simply tick the USB Only button and all the PortIO stuff gets disabled / ignored) - just ignore all that as it's the old way of doing things - X360USB PRO takes care of ALL of it.

The following tutorial will take you through the simple process of communicating with a Liteon DG-16D4S DVD Drive using Jungle Flasher and an X360USB PRO adapter. It doesn't matter what firmware you have on your drive - this method will work regardless.


  • Xecuter X360USB Pro (You MUST Update to at least v18 Firmware using at least v0.12 of the X360USB Update Tool or Slim key extraction will not work)
  • DVD Drive Power source (the tutorial uses an Xecuter CK3 Pro)
  • Sata Cable (Supplied with X360USB Pro)
  • USB Cable (Supplied with X360USB Pro)
  • Latest version of Jungle Flasher (Must be v0.1.81 and above)
  • X360USB PRO Windows Drivers
  • Windows XP / Vista / 7 - 32bit or 64bit (Can work on a MAC also if you use Bootcamp or VMWare)
There are two versions of the Liteon DG-16D4S, the 9504 and the 0225. This guide covers the 9504. To find out which version of Liteon drive you have simply look at the label and you will see "FW Ver.: XXXX"


AUX Power Cable

The X360USB PRO comes with an AUX Power cable. This is NOT to be used unless it is required. Your X360USB PRO will function with no problems on 99% of USB ports as they have a 500ma output. A tiny amount of USB ports only carry 100ma. The AUX Power is supplied as a worst case scenario for those instances (you would plug it into a USB capable power supply unit such as the iPod's power brick). DO NOT use the AUX Power cable if your computer supports 500ma as you may cause damage to your X360USB PRO. The best way to test is it just set everything up to see if drivers install, jungle flasher detects the drive etc.

Here is an example of the Liteon DG-16D4S DVD label. As you can see we have highlighted the F/W version - in this case it is the 9504.

Before you connect everything you first need to install the X360USB Pro Drivers. These are signed and work in Windows XP / Vista / 7 both 32bit and 64bit. Download the small driverpack and plug in the X360USB PRO USB Cable. When it asks for the drivers simple point to the files you saved and they will install with ease. You are now ready to hook everything else up.

It's very easy to hook up your Liteon DG-16D4S to your PC. Simply connect the DVD power supply (in this case the Xecuter CK3 Pro) to the DVD drive (take care to make sure it is fitted the correct way - the wrong way can damage your drive) and to a molex power cable from your PC or from an external Molex power supply. Then connect the SATA cable from the DVD drive to the X360USB Pro, and then connect the USB cable from the X360USB Pro to a USB port on your Netbook/Notebook/Laptop/Desktop computer.

Remember that you need to be running at least v18 of the X360USB PRO firmware, and that needs to be flashed with at least v0.12 of the X360USB PRO Update Tool. If you don't the latest JF will not work with Slims.

OK we are ready to begin:

1. Load up Jungle Flasher and...

(1) Select the MTK Flash 32 Tab
(2) Make sure the I/O Port is set to 0x000
(3) The X360USB pro should be detected as Primary Master and the Firmware version will be displayed (in this case it is Ver 0.18)
(4) The Liteon DG-16D4S should be detected and ready to work with :)
(5) Slim should be auto detected. If it isn't - select it.

NOTE: If you have updated to the dashboard 2.0.13146.0 then your fw version will now be 0272. If you have updated to dashboard version 2.0.13599.0 then your drive is now locked and you need to follow the same procedures as the 0225 and 0401 drives.

2. Now we need to put the drive into Vendor Mode.

(1) Click the Slim UnLock button
(2) The drive is now in vendor Mode

3. Now to read the firmware from the drive. Simply click on the Read button.

4. You will be asked to save the firmware file. I just created a directory called 9504 in the JF folder on the C: drive and saved it there.

5. The following part of the guide is solely to show 3rd party tools working with the X360USB PRO. You must own any game that you backup and we do not condone any kind of piracy and this is purely for educational purposes only. We do not provide any of the LT Plus firmware files and they are not provided or included with Jungle Flasher so do not ask for them. Once the drives firmware has been read Jungle Flasher will ask you if you want to auto-load the LT+ iXtreme firmware. Click Yes.

6. Everything is now loaded into Jungle Flasher and you are ready to go. Let's explain whats happening on the screen at the moment.

(1) The source buffer is loaded with the firmware from your Liteon Slim drive. It shows here that it is 9504 Stock Firmware
(2) This is your DVD key - always keep this safe !
(3) This is the LT-Plus firmware auto loaded into the target buffer

7. Now you are ready to program your drive. Goto the MTK Flash 32 tab and click the Slim Unlock button again.

8. Now click the Write button.

9. As you can see there are more complex steps to this process than Phat drive methods. All the key / inquiry / serial areas are being verified to make sure your flash is as safe as possible. When everything is good to go it will say "Authorised !"

10. Success ! From beginning to end with a X360USB PRO it should take no more than 60 seconds :)
