Premise

This guide is made exclusively for the Xbox 360 DVD player versions LiteOn 83850C v2 is LiteOn 93450C. They are the last readers, those used for all consoles produced from July-August 2009 onwards, for which it will be necessary to carry out the whole firmware dump to successfully complete the change.

The method described, called MRA, it works up all versions of LiteOn, included 74850C is 83850C v1 for which, however, there are much simpler procedures that you can find online.

The main purpose of the change is to get the unique key (along with other info) of the DVD player from the original firmware and use the key obtained to create the modified firmware iXtreme LT + and write the latter in the reader to read the backup copies.

The method described, we reiterate well, requires some skill in welding and cutting the tracks on the PCB of the reader and we strongly advise against continuing if you have never used a soldering iron and if you do not have the right tools.


What is needed

* SoftwareWindows XP with .net framework 2.0 or later (Download Net Framework 3.5). Or Windows Vista with .net framework 3.5 SP1. Or Windows 7 (already includes the .net framework) .PC with port Serial Ata (SATA), and a Serial Ata cable.JungleFlasher is iXtreme LT + firmware (JungleFlasher and Firmware LT + Download) Use the "Run as Administrator" option (in Italian: Run as administrator) for operating systems other than Windows XP x86.* ToolsA cutter, fine-grained sandpaper (optional), a brush appropriately modified if it is not already included with the flux, a switch, one 22 Ohm 1/4 watt resistor (if you don't find it, it's fine even by 1/2 watt) and finally thin wires.Welder thin point, pond thin, fluxing (optional but recommended), all as in the image below, available on ebay for around 25 euros.

Production date and reader version

To continue with this guide, necessary identify the DVD player version of the console you are in possession of. First check that the production date on the back of the console is of July or August 2009 or next one; all the consoles produced from that period have a reader LiteOn.

If you are not sure, remove the front interlocking part of the console and check that the wires present in the small hole shown in the center of the image are actually yellow color (the yellow wires indicate that it is a Philips LiteOn).

(img 3) Yellow threads indicating a LiteOn reader inside the Xbox 360

Disassemble the Xbox 360

Once we have established with certainty that our console has a reader LiteOn, we must make sure that the LiteOn version be 83850C or 93950C.

For disassemble completely L'Xbox 360, refer to ours tutorial detailed with images is video: Unmount Xbox 360, Guide with Photos and Videos

Now it is possible to read the specific version and date of production of the reader:

Preparation for the MRA Hack

Completely disassemble the reader LiteOn. Remove the cable SATA and the power cord of the reader. Unscrew the indicated screws with a Phillips screwdriver and cut the small white sticker:

Follow the images and enlargements to properly disassemble the card from the reader.

It will be enough, bring back every block that holds the data cable, as you see in the red boxes, remove the screws 1 is 2, and bring back the tooth that holds the card in place.

Very important tip: for each weld, to make the task easier, use the flux and, to apply it precisely, use a small brush to which you have cut most of the bristles, leaving only two.

(img 7) Brush modified to spread the flux precisely

That said, let's move on to soldering wires on the switch.

To the contact in correspondence with the position "OFF?Of the switch, we weld the wire which you see in green with the photo 22 Ohm resistance. At the other end of the resistance we weld another cable which will then be welded to the board in turn.

To the contact that is in the center we weld another wire (always see photo) of black colour which will then be welded to the back of the board and finally, to the contact in position ?ON?We weld a red wire. At this point, the welds on the switch side are complete.

(img 8) Switch or diverter with lever, with cables and resistance already welded, Do not panic, what you see in the picture is a plexiglass support that I built to indicate the On-Off status, and to have a greater comfort !

Let's now move on to clean the tracks on the side rear of the card where we are going to weld our wires. To do this, you can use thin sandpaper as they do in many, or, for greater precision, use a small knife with rounded blade; rubbing it slowly and repeatedly, with a little bit of manuality, you will get a perfect result by going to remove the green insulating part until you get to the original color of the slopes in copper. Perform this operation in the points you see in the image, those where the copper is visible.

(img 9) Cleaning of the tracks and cuts to be made on the card

Now we have to proceed to to cut (with a cutter) the slopes, in the points indicated in the figure (img 9). Always refer to the image above for the cut on the pad (the rod) and the one in the center of the image. Pay much attention because these tracks will then be rebuilt later, so avoid creating too large grooves.

Let us arm ourselves as a welder and proceed to weld the wires to the points shown in the figure with very little water (img 9 and img 10)

Let's start with the welds on back of the card (img10), prepare a cable of about 10 centimeters, peel the ends of the cable and weld on the board as in the image below the red wire to create a bridge.

Continue with the welding of the wire that starts from the central position of the switch, to understand the black wire that must be welded on the back of the board in the point you see in the picture.

(img 10) Part rear. Bridge (red wire) and solder switch board as you can see in the picture under the black wire to be clear!

Now let's move on to top of the card. We weld the contact cable in position "OFF?Of the switch, so to speak the one with the resistance as shown in the photo (img 11). Next, we weld the red cable connected to the switch contact in position ?ON"On the other contact 3.3 Volts, always on the front of the card (img 11).

(img 11) Part higher. Two welds, from switch to card, as you see in the picture, the green wire with the resistance, and the red wire to the 4 pin starting from the left of the lower row.

With the welds we have finished. Now that everything is ready, we can continue and read the reader firmware.


Connect DVD player to PC

What we need to do at this point, connect the DVD player (ie the card on which we have sold everything) to the PC. The reader will also go powered.

The solutions to power it they are two:

(1) power the player through the console (Img12).

(2) use a specially created kit that can be purchased online (Img13).

With the kit everything is much easier because you can completely remove the reader from the body of the console and work only on that.

(img 12) power supply via console (p.s. It is an example, the reader still mounted!).

(Important: leave the video cable connected to prevent the console from turning off every 5 minutes, if the player is powered by the console)

power supply reader via console

Connect with a cable Serial ATA the reader to a SATA port on the PC, continuing to feed it through consul or through the kit. Turn on the console or press the power button on the kit.

Position the switch in position "OFF", turn on the computer and start up JungleFlasher, the program we will use to read and write the firmware. If you haven't downloaded it go here Download JungleFlasher.

Reading the firmware via JungleFlasher

You can ignore the error "Can't install PortIo32 / 64.sys driver!"And the message"No comports found during enumeration?Which are not indispensable for this guide and for the modification of the LiteOn 84850C is 93450C.

With the'switch set to "OFF", the reader must be recognized by the program; move to the tab MTK Flash 32. Select one of the SATA ports from the I / O Port (the one where the reader is connected, you can also go to attempts) and click on the "Refresh?, As shown in the figure. Below, the DVD player will be indicated with the acronym PLDS, name DG-16D2S and firmware revision.

At this point we need to turn off the power to the reader and to do this simply turn off the Xbox or turn off the reader using the kit.

Position the switch on the position "ON", without turning on the player again (without starting the console or kit). Press as indicated on the image, the button Intro / Device ID.

At this point press YES on the window that will come out. In this way the program continually tries to send commands to the reader to get the Vendor Mode and have it correct status.

resend command

Only now can you feed the reader again. Immediately afterwards, the program should stop. We check that the flash memory has been correctly identified as shown in the figure (note also the writing Driver in Vendor Mode on the left).

Caution! If it is "Unknown type"In the chip properties, press again Intro / Device ID without turning off the player. The screen should therefore be similar to the one shown in img 15before continuing.

Once the flash memory has been correctly found, we place the switch back in position "OFF". We press on READ and if all went well, we have the dump of our firmware!read firmware from liteon

Save the complete dump on the hard disk Lite-OFW.bin so obtained when the program asks for it.save LiteOFW firmware


Writing iXtreme LT + firmware

The firmware will be loaded automatically in "Source", In the tab Firmware Tool 32. You can always load it later by clicking on "Open Source Firmware", Always in the same form Firmware Tool 32. To the question "autoload firmware …" you can answer no, if you have not previously put the firmware in a directory inside JungleFlasher.

Now we have to build the iXtreme LT + firmware for our console. Click on "Open Target Firmware?And select the iXtreme LT + firmware related to the reader in your possession (you should have already downloaded it, otherwise go to iXtreme LT + download).

Click on the central button "Spoof Source to Target"To copy the key from the original firmware of the reader to theiXtreme LT +.

(img 16) Firmware spoof

JungleFlasher-spoof

Move to the tab MTK Flash 32 and press the button WRITE to write the iXtreme LT + firmware in the LiteOn reader!

(img 17) Firmware writing successfully performed 🙂

JungleFlasher-write-firmware

Now that we have the firmware modified on the player LiteOn, we must reconstruct the tracks that we have previously cut with the cutter.


Reconstruction of the slopes

If you reassemble the reader at this point, it will no longer work and a red LED will flash on the console. We need to rearrange things as they were originally.

The success of this procedure depends on how much attention you have paid in making the cuts on the slopes.

Desolder the cables that you used in the procedure, both those connected to the switch, both the bridge and the red wire running from one track to the other. Then refer to the image of the runway cut (img 9) and, using the soldering iron, place one tin ball in order to connect the two separate estermits. Pay attention to the cut on the pad: it is sufficient that the tin is in contact with the pad.

Close the reader by performing the reverse procedure explained above and close the console. Reconnect everything and enjoy the modification of the console with LT + firmware which will also allow you to go online with your backup copies.


Conclusions

The procedure is not for everyone, but with a little effort and practice with the welder you shouldn't have big problems. If something should go wrong, for example in the reconstruction of the tracks, the important thing is to have obtained a perfect dump of the original firmware of the LiteOn player (with the key associated with your console); in case you can always replace the original reader with another LiteOn.
