So you already have iXtreme firmware 1.5 on your Xbox 360 drive, and need to update to 1.51? It’s not that hard. I did it the night iXtreme 1.51 was released, and it was a pretty easy process. I updated my Liteon DG-162s drive without issues.
First I recommend download and reading through this PDF – Jungle Flasher 1.51 Tutorial

Download the iXtreme 1.51 firmware here.
For this, I still used the CK3 Connectivity kit, which in my opinion, makes it easier for connecting it to the computer, getting the key, etc.
If you are using the VIA 6421 card, make sure you remove the drives first. Okay, let’s do that. Right Click My Computer, select properties, then click on the Hardware tab. 
Click on “Device Manager” and scroll down to “SCSI and Raid Controller”, click the + sign to expand the list. Right click on your VIA card, and click “Disable”. When prompted with a yes/no message, click yes to disable it.
Now you have to remove the driver viamraid.sys, which is found in C:\windows\system32\drivers. When you find it, just right click, and delete the file. After you delete it, go back to the device manager, and right click your via card, and enable it. Next, reboot your pc.
After you have rebooted, go ahead an install the PortIO32 drivers. Just click on PortIO32.exe, which is in the same folder as JungleFlasher ( if you haven’t already downloaded JungleFlasher, do it now – JungleFlasher 0.1.55)
Another side note, is that JungleFlasher requires the .NET 2.0, get it here.
Now you can go ahead, and hook up your drive, making sure it’s turned off to your pc. Theirs no need to have your PC turned off when you plugin in the SATA cable to your drive.
Once you have everything hooked up, the first thing it to power on the drive, open the tray, then turn off the power. Next you want to push the drive tray in, half way, then power the drive back on.
Now you can go ahead, and open up JungleFlasher. When you’re at the main screen, click on the DVDKey 32. Find the correct I/O Port and Com Port. It should be listed as PLDS DG-16D2S. Just in case your PC freezes during the Erase process, write down with I/O Port your drive is connected to.
Now theirs two ways you can go about this, you can use the “Dummy from Ixtreme” button, or, if it make you feel more safer, you can go about the same process if you were dumping the key from a stock Liteon drive, getting the key, inquiry, identify, and dummy.bin files. It doesn’t matter.
Let’s just get the “Dummy from iXtreme” button, and save as prompted. JungleFlasher will prompt you if you want to auto-load the firmware. Make sure your firmware for the drive is placed in the folder “firmware”. Click yes to auto load the firmware. When that completes, click the button, “Save to File”.
Now, the next phase is to erase the drive. Make sure that you’ve completed all the steps above, you’ve read over the PDF Tutorial, and feel comfortable proceeding.
During the erase process, if for some reason your PC freezes, don’t worry, you’ll still be able to continue flashing your drive after you reboot.
Now as long as you haven’t quit or closed JungleFlasher after you got your key, you should be good to go. If you did, make sure you have the correct I/O Port listed. Again, it should be shown as PLDS DG-16D2S. Now, let’s proceed. In JungleFlasher, click on the MTK Flash 32 tab, then click on the Lite-On erase button. Don’t be scared, do it 
When prompted to continue, click yes. You’ll now be presented with another warning message. It’s telling you, that after it’s been erased, you need to power off then on, in a quick cession.
When you see the following status as shown below, go ahead and run the power cycle. If for any reason during the erase process, your computer freezes and you start splurring kuss words, no worry, just go ahead an reboot your pc.
Now your drive is erased, you should be able to see that it is shown under Drive Properties as “Drive in Vendor Mode”
Oh, if you had to re-boot your pc, lets get you caught up. Go ahead, open JungleFlasher and go tot he MTK 32 tab. When there, make sure you drive is powered on, and select the correct I/O Port. It wont say it found anything, so I hope you wrote down what I/O Port you were in. If you didn’t, just go through each one following the next step.
On the right hand of the screen, there is a Flashing Task section, click on Intro / Devide ID. This will load your erased drive. It took me about 20 minutes after I had to reboot my pc due to it freezing. Just click that button (sorry, don’t have a screen shot for that, trust me, it’ll work). Also, since you had to reboot your pc, you’re going to have to go back to the FirmwareTool 32 tab, load the dummy file, and create your hacked firmware again. It’s pretty easy, if you need more specific help on this, just post a question in the comments area.
Now you’re all caught up, lets write to the drive.
When the process is complete, click the Outro / ATA Reset button, which will then reset your drive, and display it’s properties. To tell you the truth, I don’t think I clicked that button, and mine still worked fine. But for sakes of sanity, click it to be safe.
